After 12 months for Emma and 10 months for Evie they will have the same amount of money that is $ 2,600

Given:

Case 1 : Amount of money Emma already has = $ 2000

Amount she plans to save per month = $ 50

Thus according to the above data after 12 months Emma would have

12 × 50 = 600 + 2000

this is equal to $ 2600

Case 2 : Amount of money Evie has = $ 1,600

Amount of money she plans to save every month = $ 100

Thus after 10 months she will have 10 multiplied by 100 which is $ 1000

Thus the total amount she will have = 1000 + 1600

which is equal to $ 2,600

Thus after 12 months for Emma and 10 months for Evie they will have the same amount of money that is $ 2,600

Answer:

The best estimate for her earnings is $1200

Step-by-step explanation:

Number of time spent babysitting each week = 21 hours = BBS

Number of time spent dog walking each week = 9 hours = DW

She earns $7.50 per hour for dog walking,

She earns $(7.50+1.50) = $9 for baby sitting,

There are 4 1/2 weeks = 9/2 weeks in July,

Now, for each week she earns 21(9) = $189 from baby sitting

and 9(7.5) = $67.5 from dog walking,

So, for the month of July, i.e. 9/2 weeks, she earns,

9/2(189) = $ 850.5 from baby sitting,

and (9/2)(67.5) = $303.75 from dog walking,

In total for the month, she earns,

850.5 + 303.75 = $1154.25

Hence the best estimate for her earnings is $1200

The explicit solution of the initial value problem y′=y(y−1), y(0)=4 is y = 1/(1-3e^-x).

To find the explicit solution, we begin by separating the variables and integrating both sides:

dy/dx = y(y-1)

(dy/y(y-1)) = dx

Integrating both sides yields

ln|y-1| - ln|y| = -x + C

where C is a constant of integration.

We can simplify this expression by combining the logarithms using the identity ln(a/b) = ln(a) - ln(b):

ln|(y-1)/y| = -x + C

Taking exponential of both sides gives

|(y-1)/y| = e^(C-x)

Letting k = e^C, we can rewrite this as:

(y-1)/y = ± k e^-x

Rearranging and solving for y, we obtain:

y = 1/(1-k e^-x )

We can determine the value of k using the initial condition y(0) = 4:

4 = 1/(1-k)

Solving for k gives k = 3.

Substituting k=3 into the expression for y, we get:

y = 1/(1-3e^-x)

Therefore, the explicit solution of the initial value problem is y = 1/(1-3e^-x), where y(0) = 4.

The graph of g(x) is the graph of f(x) stretched vertically and reflected over the axis.

The correct option is C.

We can compare the graphs of two functions f(x)=x² and g(x)=-2/3 x² by determining their vertices, domain, range, axis of symmetry, and shape of the graphs. The vertex of f(x)=x² is at the origin (0,0), which means that the parabola opens upward and is symmetrical around the y-axis.

The domain is all real numbers, and the range is y≥0. The axis of symmetry is the y-axis. On the other hand, the vertex of g(x)=-2/3 x² is also at the origin, and it opens downward. It is also symmetrical around the y-axis. The domain is all real numbers, and the range is y≤0.

The axis of symmetry is the y-axis, just like f(x).It is important to remember that g(x) is the negative of f(x), which indicates that g(x) is reflected across the x-axis. Furthermore, the stretch factor is 2/3, which makes the graph of g(x) flatter than the graph of f(x) and it is  stretched vertically and reflects over x axis(option c).

Step-by-step explanation:

The value of the identity cos(π/2 + x) = -sin(x). The sum formula for cosine is

cos(π/2 + x) = cos(π/2)cos(x) - sin(π/2)sin(x)

To establish the identity cos(π/2 + x) = -sin(x), we can use the sum formula for cosine and the definition of sine.

Using the sum formula for cosine, we have:

cos(π/2 + x) = cos(π/2)cos(x) - sin(π/2)sin(x)

Now, we know that cos(π/2) = 0 and sin(π/2) = 1, so we can substitute these values:

cos(π/2 + x) = 0 * cos(x) - 1 * sin(x)

Simplifying further, we get:

cos(π/2 + x) = -sin(x)

Therefore, we have established the identity cos(π/2 + x) = -sin(x).

The Correct answer is A. (-4,1) ordered pair generated by this model should be discarded because the values are unreasonable.

In algebra, a quadratic equation (from Latin quadratus 'rectangular') is any equation that can be rearranged in well-known form as ax²+bx+c=0 Where x represents an unknown value, and a, b, and c constitute recognized numbers.

One supposes usually that a ≠ zero; the one's equations with a = zero are taken into consideration degenerate because the equation then will become linear or even simpler. The numbers a, b, and c are the coefficients of the equation and can be prominent with the aid of calling them, respectively, the quadratic coefficient, the linear coefficient, and the consistent or loose time period.

The values of x that satisfy the equation are referred to as answers to the equation, and roots or zeros of the expression on its left-hand aspect. A quadratic equation has at most two answers. If there is handiest one solution, one says that it's miles a double root. If all the coefficients are real numbers, there are both actual solutions, a single actual double root, or two complicated answers which can be complicated conjugates of each other.

Based on the given conditions, Jane has $31, Kevin has $25, and Hans has $50 in their wallets.

Let's solve the problem step by step.

First, let's assume that Jane has X dollars in her wallet. Since Kevin has $6 less than Jane, Kevin would have X - $6 dollars in his wallet.

Next, we're given that Hans has 2 times what Kevin has. So, Hans would have 2 * (X - $6) dollars in his wallet.

According to the information given, the total amount of money they have in their wallets is $106. We can write this as an equation:

X + (X - $6) + 2 * (X - $6) = $106

Simplifying the equation:

4X - $18 = $106

4X = $124

X = $31

Now we know that Jane has $31 in her wallet.

Substituting this value into the previous calculations, we find that Kevin has $31 - $6 = $25 and Hans has 2 * ($25) = $50.

To find the total amount they have, we sum up their individual amounts:

Jane: $31

Kevin: $25

Hans: $50

Adding these amounts together, we get $31 + $25 + $50 = $106, which matches the total amount stated in the problem.

Janet can simplify and solve the resulting equation to find the Value(s) of y.(y^2 - 1)(y + 1) * (y + y^2 - 5) = (y^2 - 1)(y + 1) * (y^2 + y + 2)

To solve the equation y + y^2 - 5 / (y^2 - 1) = y^2 + y + 2 / (y + 1), Janet needs to get rid of the denominators in order to simplify the equation and solve for y. One way to do this is by multiplying both sides of the equation by the common denominator of all the fractions involved.

In this case, the common denominator is (y^2 - 1)(y + 1). So, Janet should multiply both sides of the equation by (y^2 - 1)(y + 1) to eliminate the denominators.

Multiplying both sides by (y^2 - 1)(y + 1) yields:

(y^2 - 1)(y + 1) * (y + y^2 - 5) / (y^2 - 1) = (y^2 - 1)(y + 1) * (y^2 + y + 2) / (y + 1)

By multiplying, we cancel out the denominators:

(y^2 - 1)(y + 1) * (y + y^2 - 5) = (y^2 - 1)(y + 1) * (y^2 + y + 2)

Now, Janet can simplify and solve the resulting equation to find the value(s) of y.

Reaction time refers to the time it takes for someone to respond to a stimulus. It's composed of two components: perception time and decision time.

The time it takes to move your foot from the gas pedal to the brake pedal can be estimated using the formula r=(5 m/s2 )=t1/2 , and the total reaction time is t1+t2. The acceleration magnitude, -a0, can be calculated using this formula: -a0 = Δv/t.

When we use the negative sign in front of the acceleration magnitude, we indicate that it is directed in the opposite direction of motion.

To calculate how far the car in front of you will travel before it stops, use the formula s = vi*t + 0.5*a*t2. The average velocity during this time interval is the displacement divided by the time.

Using the values from parts A and B, the distance you travel before applying the brakes is 44 meters, and the total distance you travel before stopping is 70 meters.

If you do not detect that the car in front of you is braking for one second, you will travel an additional 28 meters.

The recommended safe distance to stay behind a car at 60 mph is 3 car lengths.

The question deals with estimating the reaction time of a driver and the distance one would travel before coming to a halt in an emergency.

It is important to know the reaction time because it can help reduce the number of accidents caused by a driver's lack of responsiveness.

The formula r = (5 m/s2) = t1/2 can be used to estimate the time it takes to move one's foot from the gas pedal to the brake pedal.

This reaction time is composed of two components: perception time and decision time. When a driver detects a stimulus and decides how to react, these two components are used.

The magnitude of acceleration, -a0, can be calculated using this formula: -a0 = Δv/t.

When we use the negative sign in front of the acceleration magnitude, we indicate that it is directed in the opposite direction of motion. This formula assumes that the acceleration is constant, which is reasonable for small time intervals.
The distance that the car ahead of you will travel before stopping can be calculated using the formula s = vi*t + 0.5*a*t2, where s is the distance traveled, vi is the initial velocity, t is the time it takes to stop, a is the acceleration, and t2 is the time it takes to travel s meters.
The average velocity during this time interval is the displacement divided by the time.

To calculate the distance you travel before applying the brakes, use the formula s = vt + 0.5*a*t2. In this case, the distance is calculated using the driver's reaction time, which is t1 + t2.

If you do not detect that the car in front of you is braking for one second, you will travel an additional 28 meters. This suggests that drivers should be cautious and keep a safe distance from the vehicle in front of them to avoid accidents. The recommended safe distance to stay behind a car at 60 mph is 3 car lengths.

The expected amount to be paid by the carnival committee for prices would be $366.80

Step-by-step explanation:

Hello!

Here, we want to calculate the amount of money the carnival committee is expected to pay for the prizes for that booth

From the question, we have 3 categories of prices to be won

To calculate for people that won’t win anything , we simply subtract the percentages of all from 100

That would be 100-32-10-8 = 100-50 = 50%

So now let’s calculate the number of people out of 200 that will win each category based on the percentages

For stuffed toy

32/100 * 200 = 64

Jump rope

10/100 * 200 = 20

For t-shirt

8/100 * 200 = 16

So total price paid for stuffed toy= 3.25 * 64 = $208

For jump rope, we have 1.7 * 20 = $34

For t-shirt , we hav 16 * 7.8 = $124.8

So the total value spent on prices by the committee would be;

124.8 + 34 + 208 = $366.80

⇒ ( x² - 5 )² - 3x² + 15 = -2

Take '3' common factor from the 3x² + 15 so that it get convert into x² - 5 we get,

⇒ ( x² - 5 )² - 3 (x² - 5 )  = -2

Now replace x² - 5 by m to get the equivalent equation,

⇒ ( m )² - 3 (m ) = -2

Given that a raj measures the height of 70 plants which is shown in the table in the image attached below.

The mean is defined as the mean value equal to the ratio of the total number of a given set of values ​​to the total number of values ​​contained in that set.

Firstly, we will find the midpoint of the height by using the formula

(upper limit +lower limit)/2

When h is 10<h<20 then the midpoint is

x₁=(10+20)/2

x₁=15

When h is 20<h<0 then the midpoint is

x₂=(20+40)/2

x₂=30

When h is 40<h<50 then the midpoint is

x₃(40+50)/2

x₃=45

When h is 50<h<60 then the midpoint is

x₄=(50+60)/2

x₄=55

When h is 60<h<90 then the midpoint is

x₅=(60+90)/2

x₅=75

Now, we will find the mean height by using the formula

x=(f₁x₁+f₂x₂+f₃x₃+f₄x₄+f₅x₅)/(Σfi)

Here, f₁=7,f₂=15,f₃=27,f₄=13,f₅=8

and Σfi=7+15+27+12+8=70

Substitute these values in the formula, we get

x=(7×15+15×30+27×45+12×55+8×75)/70

x=(105+450+1215+715+600)/70

x=(3085)/70

x=44.07
