Answer:

a = 2, b = - 3, c = - 8

Step-by-step explanation:

Expand f(x) = a(x + b)² + c and compare coefficients of like terms, that is

a(x + b)² + c ← expand (x + b)² using FOIL

= a(x² + 2bx + b²) + c ← distribute parenthesis by a

= ax² + 2abx + ab² + c

Compare like terms with f(x) = 2x² - 12x + 10

Compare coefficients x² term

a = 2

Compare coefficients of x- term

2ab = - 12, substitute a = 2

2(2)b = - 12

4b = - 12 ( divide both sides by 4 )

b = - 3

Compare constant term

ab² + c = 10 , substitute a = 2, b = - 3

2(- 3)² + c = 10

18 + c = 10 ( subtract 18 from both sides )

c = - 8

Then a = 2, b = - 3, c = - 8

Answer: 264.66 lbs

Step-by-step explanation:

120.3×2.2= 264.66

David weight his next weightlifting competition would be 264.66 pounds

Used the concept of measurement unit which states that,

A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.

Given that,

David is traveling to the United States for his next weightlifting competition.

And, His weighs 120.3 kilograms.

Now, Change the weight into pounds as,

1 kg = 2.2 lb

Hence, it can be,

120.3 kg = 120.3 × 2.2 lb

= 264.66 pounds

Therefore, He weighs 264.66 pounds.

The first step of indirect proof of the conditional below

If x2 = 25, then 5’2= 25 and x = 5 is assume 5² = 25.

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Conditions:

x² = 25 then 5² = 25 and x = 5

If we have to prove the above conditions indirectly, we have to prove that x² = 25 using the conditions 5² = 25 and x = 5.

So,

We have to assume,

Step 1:

5² = 25

Step 2:

x = 5

Step 3:

x² = 25

Thus,

One of the Answers is C

Answer:

Reyna Puti sold = 20 bottles

Step-by-step explanation:

Silver duck = Php 10 per bottle

Reyna Puti = Php 15 per bottle

Silver duck sold = 30 bottles

Reyna Puti sold = x bottles

Total sales = Php 600.00

Total = cost of Silver duck * number sold + cost of Reyna Puti * number sold

600 = 10 * 30 + 15 * x

600 = 300 + 15x

600 - 300 = 15x

300 = 15x

x = 300/15

x = 20 bottles

Reyna Puti sold = 20 bottles

Each x-value is paired with its corresponding y-value, which is calculated by multiplying the x-value by 8 and adding 2. For example, when x = 1, y= 8(1) + 2 = 10.

Compound interest is a method of calculating interest where the interest earned on an investment is added to the principal amount, and the interest on the new total is calculated for the next period. This process continues over time, resulting in the gradual growth of the investment.

Answer:

y = -(3/5)x - 6

Step-by-step explanation:

Lets look for an equation of the form y=mx+b, where m is the slope and b the y-intercept(the value of y when x=0).  We are given a reference line of 3x+5y = 15.  Let's rearrange that into standard form:

3x+5y = 15

5y = -3x+15

y = -(3/5)x+3

This tells us that the slope of the reference line is -(3/5).  Parallel lines have the same slope.

So we know the new line must use m = -(3/5) to be parallel.

This leads to:

 y = -(3/5)x + b

Any value of b will still result in a parallel line.  But we want OUR parallel line to go through point (-5,-3).  To find a value of b that would make that happen, enter the given point into the above equation:

y = -(3/5)x + b

(-3) = -(3/5)(-5) + b  for point (-5,-3)

Now solve for b:

(-3) = -(3/5)(-5) + b

(-3) = 3 + b

b = -6

The parallel line that goes through point (-5,-3) is y = -(3/5)x - 6

See the attached graph.

Answer:

Step-by-step explanation:

If function f(x) = 2x2 + 3x – 1 and g(x) = -x, then f(-1)+g( - 1) = -1

To solve this problem, we need to plug in -1 for x in both f(x) and g(x).

f(-1) = 2(-1)2 + 3(-1) – 1 = 2 - 3 - 1 = -2

g(-1) = -(-1) = 1

Now, we can add f(-1) and g(-1):

f(-1) + g(-1) = -2 + 1 = -1


To solve f(-1) + g(-1), we need to first find the values of f(-1) and g(-1) individually.

For f(-1):
f(x) = 2x^2 + 3x - 1
f(-1) = 2(-1)^2 + 3(-1) - 1
f(-1) = 2(1) - 3 - 1
f(-1) = 2 - 3 - 1
f(-1) = -2

For g(-1):
g(x) = -x
g(-1) = -(-1)
g(-1) = 1

Now, let's add f(-1) and g(-1):
f(-1) + g(-1) = -2 + 1 = -1

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/7 is 7/3) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

Answer:

Sentence Fram: I found x-intercept by substitute y by 0 and I found y-intercept by substitute x by 0

x-intercept = (6, 0), y-intercept = (0, -3) ⇒ C

Step-by-step explanation:

∵ The equation of the graph is 6x - 12y = 36

→ Equate y by 0 to find x

∵ y = 0

∴ 6x - 12(0) = 36

∴ 6x - 0 = 36

∴ 6x = 36

→ Divide both sides by 6 to find x

∴ x = 6

∴ The x-intercept = (6, 0)

→ Equate x by 0 to find y

∵ x = 0

∴ 6(0) - 12y = 36

∴ 0 - 12y = 36

∴ -12y = 36

→ Divide both sides by -12 to find y

∴ y = -3

∴ The y-intercept = (0, -3)

∴ Sentence Fram: I found x-intercept by substitute y by 0 and I found

   y-intercept by substitute x by 0

∴ x-intercept = (6, 0), y-intercept = (0, -3)

The equation is given, N(a) = 2.925 sin ( 3.65 ) + 12.18, which models the number of hours of daylight in New York City d days after March 21, 2010.

To solve the equation 11.5 = 2.925 sin (27 d) + 12.18 over the interval [0°, 720°), we need to isolate the sine function on one side of the equation.

Subtracting 12.18 from both sides, we get:
-0.68 = 2.925 sin (27 d)
Dividing both sides by 2.925, we get:
sin (27 d) = -0.2333
To find d, we need to use the inverse sine function (\(sin^{-1}\)) on both sides:
27 d = \(sin^{-1}\) (-0.2333)
Using a calculator, we find that \(sin^{-1}\) (-0.2333) = -13.5° or -0.235 radians (rounded to three decimal places).
Dividing both sides by 27, we get:
d = -0.0087 radians / 27
d = -0.00032 radians (rounded to five decimal places)
To make sense of this answer in the context of the problem, we need to convert radians to days.
One complete cycle of the sine function occurs over 360 degrees or 2π radians. Therefore, over the interval [0°, 720°), there are two complete cycles or 4π radians.
To find the number of days, we can set up a proportion:
4π radians = 365 days - 80 days (March 21 to June 9)
Solving for one radian, we get:
1 radian = (365 - 80) days / 4π
1 radian ≈ 71.3 days
Substituting this value, we get:
d = -0.00032 radians x 71.3 days/radian
d ≈ -0.023 days

The domain of the step function f(x) = [2x] - 1, where [2x] represents the greatest integer less than or equal to 2x, can be determined by considering the restrictions on the input values.

In this case, the step function is defined for all real numbers. However, the greatest integer function imposes a restriction. Since the greatest integer function only outputs integers, the input values (2x) must be such that they produce integer outputs.

For any real number x, the greatest integer less than or equal to 2x will always be an integer. Therefore, the domain of the function f(x) = [2x] - 1 is:

Answer:

Step-by-step explanation:

We can first multiply the 2 and 4 together to get 8.

Wow we already eliminated A.

When you have negative powers, you can just replace it with their inverse and turn the power positive.

For example, 2 to the power of -3  (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).

So we now have 8  (x^4 / yx^2

We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.

For example, x^5  divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.

So we have 8 ( x^2y)
