If Isabelle chooses to read 5 books
with a total of 1260 pages, how much would she earn? And find the equation

Answer: The slope of the line is 6.

You can use the distance formula to find the slope (Y2-Y1/X2-X1). You can plug in any two points seen on the graph into the formula. I will use (0,-1) and (1,5). When I plug in the values, 5-(-1)/1-0=6/1=6. So the slope of the line is 6.

:)

Given the provided coordinates of the points, The shape that is formed is a parallelogram because the slopes of the opposite sides are same.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Divide the difference in elevation between two points by the distance between them to find the percent slope, then multiply the result by 100. The term "rise" refers to the difference in elevation between two sites. The run is the separation between the points. Percent slope is therefore equal to (rise / run) x 100.

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.

slope between (1,1) and (4,4),

m1 = 4-1/4-1 =3/3 =1

slope between (4,-2) and (7,1),

m2= 1+2/7-4 = 3/3 =1

m1=m2

similarly, slope between (1,1) and (4,-2),

m3= -2-1/4-1 = -3/3 =-1

slope between (7,1) and (4,4)

m4= 1-4/7-4 = -3/3 =-1

m3=m4

So, slopes of opposite sides are same that means they are parallel, The shape is parallelogram.

Answer:

A. B = 5

Step-by-step explanation:

Joe:

J(b) = 14b + 7

Will:

W(b) = 7b + 42

Where,

b = number of hamburgers cooked

J(b) and W(b) = amount of time each cook takes in minutes respectively

At what value of b will their cooking time be equivalent?

Equate both functions

Joe = Will

14b + 7 = 7b + 42

Collect like terms

14b - 7b = 42 - 7

7b = 35

Divide both sides by 7

b = 35 / 7

= 5

b = 5

The answer is

A. B = 5

Answer:

the third graph

Step-by-step explanation:

its the only one that has a y intercept of 3 and if you plug in each of the values of x it is correct

The solution of the real matrix A for the fundamental set of solution y' =Ay is given by y1(t) = e^(5t)(cos(3t) − sin(3t)) and y2(t) = e^(5t)(cos(3t) + sin(3t)).

Let A be written as A = P + iQ, where P and Q are real matrices,

Since the eigenvalue is complex, the matrix A must have complex entries.

We have,

Av = λv,

where v = −1 + i is the eigenvector.

(Av)

= (P + iQ)(−1 + i)

= (−P − Q) + i(-Q + P)

= λ(−1 + ii)

= (−5 + 3i)(−1 + i)

= 2 − 8i.

Equating real and imaginary parts, we get two equations,

−P − Q = 2,

- Q + P = −8.

Solving for P and Q, we get

-2Q = -6

⇒ Q = 3

⇒ P = -5

P = 3 − i,

Q = 1 + 3i.

Thus, A = P + iQ

            = -5 + 3i

Now, we can find the real and imaginary parts of e^(λt)v,

e^(λt)v

= e^((5 + 3i)t)(−1 + i)

= e^(5t)e^(3it)(−1 + i)

= e^(5t)(cos(3t) − sin(3t) + i(cos(3t) + sin(3t))).

The real part of e^(λt)v gives a real solution,

so we take y1(t) = Re(e^(λt)v),

y1(t) = e^(5t)(cos(3t) − sin(3t)).

The imaginary part of e^(λt)v gives an imaginary solution,

so we take y2(t) = Im(e^(λt)v).

y2(t) = e^(5t)(cos(3t) + sin(3t)).

Thus, a fundamental set of solutions for y′ = Ay consisting entirely of real solutions is given by y1(t) and y2(t) is equal to e^(5t)(cos(3t) − sin(3t)) and

e^(5t)(cos(3t) + sin(3t)) respectively.

The conditional probability that a student is studying Spanish given that he or she is studying some language other than English is 0.634.

What is conditional probability?

Conditional probability is a metric for determining the likelihood of an event happening provided that another event has already happened.

According to the given question:

From the image we can see the probability of studying different languages.

Given probability of studying no languages is P(none) = 0.59

From this we can find the probability of studying another language using complement rule = 1 - P(none) = 1 - 0.59 = 0.41

It is given probability of studying Spanish P(Spanish) = 0.26

So the conditional probability of studying Spanish

= P(Spanish) / P(Studying another language)

= 0.26/0.41 = 0.634

Therefore  the conditional probability that a student is studying Spanish given that he or she is studying some language other than English is 0.634.

Step-by-step explanation:

From the given resistivities, the largest and the smallest will be as follows:

ρ2>ρ3>ρ1=ρ5>ρ4.

The resistance of a wire is given as,

R= ρL/A

Here, p is the resistivity of the wire, L is the length of the wire, and A is the area of the wire.

Rearrange the equation R = ρL/A in terms of ρ.

ρ=RA/L

Let R be the resistance of each wire.

The resistivity of the wire 1 is,

\(p_{1}=\frac{A_{1} }{L_{1} } *R\)

ρ1= π\(r^{2}\)\(\frac{R}{L}\)

The resistivity of the wire 2 is,

\(p_{2}=\frac{A_{2} }{L_{2} } *R\)

ρ2= 4(π\(r^{2}\)\(\frac{R}{L}\))

The resistivity of the wire 3 is,

\(p_{3}=\frac{A_{3} }{L_{3} } *R\)

ρ3= 2(π\(r^{2}\)\(\frac{R}{L}\))

The resistivity of the wire 4 is,

\(p_{4}=\frac{A_{4} }{L_{4} } *R\)

ρ3= 0.5(π\(r^{2}\)\(\frac{R}{L}\))

The resistivity of the wire 5 is,

\(p_{5}=\frac{A_{5} }{L_{5} } *R\)

ρ5= (π\(r^{2}\)\(\frac{R}{L}\))

Therefore from the above equations, we come to get the resistivities of ρ1 to ρ5. They are: ρ2>ρ3>ρ1=ρ5>ρ4.

Using the laws of cosines we know that to get the ball back to the pitcher, the outfielder must throw it 125 feet.

The square of a side of a plane triangle is equal to the sum of the squares of the other sides minus twice the product of those sides and the cosine of the angle between them, according to a trigonometry rule.

So, it is a given that the distance between the home plate and the pitcher's mound on a softball field is 43 feet.

27° east of the pitcher's mound is the angle at which a ball is struck.

Before an outfielder catches the ball, it travels 162 feet.

Using the law of cosines, we may now:

a² = b² + c² - 2bcosA

When b=43, c=162, and A=27° are entered, we get:

a² = 43² + 162² - 2(43)(162)cos27°

a² = 1849 + 26244 - 12413.4

a² = 15679.6

a = 125.21

a = 125ft

Therefore, using the laws of cosines we know that to get the ball back to the pitcher, the outfielder must throw it 125 feet.

The p-value can be found with the F-distribution table or statistical software. If the p-value is less than or equal to α, then answer is option (a),If the p-value is greater than α, then answer is option (b).

To determine the correct statistical decision based on the given F-statistic, F (3, 12) = 2.72, we need additional information such as the significance level (α) of the hypothesis test. The significance level is a predetermined threshold that is used to assess the statistical significance of the results.

The correct decision depends on whether the calculated p-value, which quantifies the strength of evidence against the null hypothesis, is less than or equal to the significance level (α).

To find the p-value, you would need the F-distribution table or statistical software.

Once you have the p-value, you can compare it to the significance level (α) to make a decision:

If the p-value is less than or equal to α, you would reject the null hypothesis, indicating a statistically significant mean difference.

If the p-value is greater than α, you would fail to reject the null hypothesis, suggesting that there is not a statistically significant mean difference.

Therefore, without the significance level or the p-value, it is not possible to determine the correct statistical decision.

Answer:

To solve for x, we need to isolate it on one side of the equation by performing inverse operations.

11x - 10 + 80 = 180

First, we combine the constant terms on the left side of the equation:

11x + 70 = 180

Next, we isolate the variable term by subtracting 70 from both sides:

11x = 110

Finally, we solve for x by dividing both sides by 11:

x = 10

Therefore, the solution to the equation 11x - 10 + 80 = 180 is x = 10.

To find an explicit formula for the nth term of the sequence satisfying\(\(a_1 = 0\) and \(a_n = 2a_{n-1} + 1\) for \(n \geq 2\),\)  we can use recursive formula to generate the terms of the sequence.

Given:

\(\(a_1 = 0\)\\\(a_n = 2a_{n-1} + 1\) for \(n \geq 2\)\)

Using the recursive formula, we can generate the terms of the sequence as follows:

\(\(a_2 = 2a_1 + 1 = 2(0) + 1 = 1\)\\\(a_3 = 2a_2 + 1 = 2(1) + 1 = 3\)\)

\(\(a_4 = 2a_3 + 1 = 2(3) + 1 = 7\)\\\(a_5 = 2a_4 + 1 = 2(7) + 1 = 15\)\)

From the pattern, we observe that the nth term of the sequence is given by \(\(2^{n-2} - 1\).\)

Therefore, the explicit formula for the nth term of the sequence satisfying \(\(a_1 = 0\) and \(a_n = 2a_{n-1} + 1\) for \(n \geq 2\) is: \\\\\a_n = 2^{n-2} - 1.\]\)
