Answer:

Zeros are x = 1.5, -2.5

Step-by-step explanation:

Given function is,

F(x) = 4x² + 4x - 15

      = 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]

F(x) = 4(x² + 2.5x - 1.5x - 3.75)

      = 4[x(x + 2.5) - 1.5(x + 2.5)]

      = 4(x - 1.5)(x + 2.5)

For 'x' intercepts,

f(x) = 0

4(x - 1.5)(x + 2.5) = 0

x = 1.5, -2.5

Therefore, zeros of the given function are x = 1.5, -2.5.

Answer:

The zeroes are: -3 and -2

Step-by-step explanation:

f(x) = x² + 5x + 6

This is the in the format...

ax² + bx + c

To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.

The two numbers are...

3 + 2 = 5 (This is correct because the two numbers add are equal to B)

3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)

You then know that you have ( x + 3 ) and ( x + 2 )

Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.

Here's what I mean by that...

x + 3 = 0

Subtract 3 on both sides...

x = -3

The other zero...

x + 2 = 0

Subtract 2 on both sides...

x = -2

Your answers are x = -2 and x = -3, make sure you always set your answers to zero.

Hope this helps!

Answer:

6 ; 24 ; 5.4 ; 24.6

Step-by-step explanation:

Given that:

Number of samples from each high school = 30

Proportion of students from high school A = 20%

Proportion of students from high school B = 18%

Number of sample A ; n(A) = 30

Proportion of sample A ; p(A) = 0.20

Number of sample B ; n(B) = 30

Proportion of sample B ; p(B) = 0.18

1.)

n(A).p(A) = 30 * 0.20 = 6

2.)

n(A). (1 - p(A))

30 * (1 - 0.20)

30 * 0.8 = 24

3.)

n(B).p(B) = 30 * 0.18 = 5.4

4.)

n(B). (1 - p(B))

30 * (1 - 0.18)

30 * 0.82

= 24.6

Shape of sampling distribution is not approximately normal ;

Both nApA and nBpB are < 10

28.04996

Step-by-step explanation:

a² + b² = c²

(2x)² + x² = 62²

4x² + x² = 3844

5x² = 3844

x² = 3844÷5

x² = 768.8

x =

[tex] \sqrt{768.8} [/tex]

x = 28.04996

Answer:

4(x+4)

Step-by-step explanation:

Find to GCF of 4x+16.

Now factor out the GCF by dividing each term in the expression by 4.

4x divided by the GCF is x, and 16 divided by the GCF is 4.

The equivalent expression is 4(x+4).

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Step-by-step explanation:

Answer:

14.940306992% or 15%

Step-by-step explanation:

To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.

$ 175.90 - $ 149.62 = $26.28

Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.

$26.28 / $175.90

= 0.14940306992

Finally, multiply by 100 and round up to reach a percentage.

Answer:

Hannah sold 4

Kiera sold 6

Total Subscriptions = 10

Step-by-step explanation:

K = number of Kiera subscriptions

H = number of Hannah subscriptions

T = hours

6+K = 4+2H

K = 2H-2

K+H = 10

K= 10-H

substitute for K

2H-2 = 10-H

simplify

3H = 12

H = 4

K = 6

Answer:

The y-intercept of the function and the vertex of the function would change. (III and IV) This answer doesn't seem to be in the answer list (but there is proof for the answers below), though.

Step-by-step explanation:

(Notice that [tex]2f(x-4) = 2(x-4)^2.[/tex])

The domain of the function won't change because quadratics can all take all numbers as their input (which, by definition, is the domain of a function).

The range of the function won't change either, because we have just moved the function with 4 to the right (by substituting [tex]x[/tex] with [tex]x-4[/tex]) and multiplied the graph with respect to the y-axis by 2. The range will stay as all non-negative real numbers.

The y-intercept of the function will change, because for [tex]f(x)=x^2[/tex] it is [tex]y=0[/tex], while for [tex]y=2(x-4)^2[/tex] substituting [tex]x=0[/tex] doesn't give [tex]y=0[/tex]. (Instead, it gives [tex]y=32[/tex].)

The vertex of the function will change, because we have moved the function with 4 to the right and multiplied the graph with respect to the y-axis by 2: the vertex will have at the very least moved to the right.
