Answer:

[tex]y=(x-3)^{2} -25[/tex]

Step-by-step explanation:

The standard form of a quadratic equation is [tex]y=ax^{2} +bx+c[/tex]

The vertex form of a quadratic equation is [tex]y=a(x-h)^{2} +k[/tex]

The vertex of a quadratic is (h,k) which is the maximum or minimum of a quadratic equation. To find the vertex of a quadratic, you can either graph the function and find the vertex, or you can find it algebraically.

To find the h-value of the vertex, you use the following equation:

[tex]h=\frac{-b}{2a}[/tex]

In this case, our quadratic equation is [tex]y=x^{2} -6x-16[/tex]. Our a-value is 1, our b-value is -6, and our c-value is -16. We will only be using the a and b values. To find the h-value, we will plug in these values into the equation shown below.

[tex]h=\frac{-b}{2a}[/tex] ⇒ [tex]h=\frac{-(-6)}{2(1)}=\frac{6}{2} =3[/tex]

Now, that we found our h-value, we need to find our k-value. To find the k-value, you plug in the h-value we found into the given quadratic equation which in this case is [tex]y=x^{2} -6x-16[/tex]

[tex]y=x^{2} -6x-16[/tex] ⇒ [tex]y=(3)^{2} -6(3)-16[/tex] ⇒ [tex]y=9-18-16[/tex] ⇒ [tex]y=-25[/tex]

This y-value that we just found is our k-value.

Next, we are going to set up our equation in vertex form. As a reminder, vertex form is: [tex]y=a(x-h)^{2} +k[/tex]

a: 1

h: 3

k: -25

[tex]y=(x-3)^{2} -25[/tex]

Answer:

b=22

Step-by-step explanation:

1 Remove parentheses.

b-11-29=-18b−11−29=−18

2 Simplify b-11-29b−11−29 to b-40b−40.

b-40=-18b−40=−18

3 Add 4040 to both sides.

b=-18+40b=−18+40

4 Simplify -18+40−18+40 to 2222.

b=22b=22

Answer:

f(x) * g(x)

Step-by-step explanation:

Hours worked per week = 45 hours

Weekly salary = $850 plus ;

3.5% commission on sales above $6,500

Given the functions :

f(x) = 0.035x and

g(x) = x - 6,500

and the fact that Joe’s dad sold enough this week to earn commission, which composition function represents Joe’s dad’s commissions ?

Commission = 3.5 / 100 = 0.035

Let his sales for the week = x ; since his sales exceeds 6,500

Hence, sales on which commission is payable is x - 6,500

Hence, commission for the week :

0.035 × (x - 6,500)

f(x) = 0.035 ; g(x) = (x - 6,500)

Composition function:

f(x) * g(x)

Answer:

Reliability= 149.94

Step-by-step explanation:

Field data have indicated that Unit A has a failure rate of 0.0004 failure per hour.

Reliability per hour=1- failure rate

Reliability per hour= 1-0.0004

Reliability per hour= 0.9996

Reliability= rate if reliability * number of hours

Rate of reliability= 0.9996 per hour

Number of hours= 150 hours

Reliability= 0.9996*150

Reliability= 149.94

Answer:

[tex]\sec^2(\theta)=\frac{25}{16}[/tex]

Step-by-step explanation:

Recall what the relationship between cosine and secant:

[tex]\sec(\theta)=\frac{1}{\cos(\theta)}[/tex]

In other words, secant is the reciprocal of cosine.

So, if we know cosine, we only need to find its reciprocal to find secant.

We are given that cosine is:

[tex]\cos(\theta)=\frac{4}{5}[/tex]

Then secant must be:

[tex]\sec(\theta)=\frac{5}{4}[/tex]

So:

[tex]\sec^2(\theta)=(\frac{5}{4})^2[/tex]

Square:

[tex]\sec^2(\theta)=\frac{25}{16}[/tex]

And we're done!

Answer:

v = -5

Step-by-step explanation:

Step 1: Write out equation

-8 + 5v = -33

Step 2: Add 8 on both sides

-8 + 8 + 5v = -33 + 8

5v = -25

Step 3: Divide both sides by 5

5v/5 = -25/5

v = -5

Answer:

Solve

-8 +5v=-33

So 5v=-33+8

(-8 became 8 because we brought it back to the other side to have the v 《5v》 alone and the numbers alone )

5v= -25

So v=-25/5

We simplify -25/5

v=-5

Answer:

84

Step-by-step explanation:

The equation that models this situation is 1110 = 15x + 150 where x = cameras sold (note that this doesn't include the first 20 cameras, we'll add those on at the end). Let's solve for x!

1110 = 15x + 150

960 = 15x

x = 64 so the answer is 64 + 20 = 84 cameras.

Answer:

The answer is below

Step-by-step explanation:

The relative frequency is the proportion of a class or interval within a category. It is represented by the formula:

Relative frequency = frequency / total frequency

The percent frequency is the relative frequency expressed in percentage, it is given by the formula:

Percent frequency = Relative frequency × 100%

Using the formulas above, the table is filled:

The total frequency = 39

Class           Frequency     Relative frequency         Percent frequency

12 - 14                  2                  2/39 = 0.0513              0.0513 × 100% = 5.13%

15 - 17                  8                  8/39 = 0.2051              0.2051 × 100% = 20.51%

18 - 20                 11                 11/39 = 0.2821              0.2821 × 100% = 28.21%

21 - 23                  9                 9/39 = 0.2308             0.2308 × 100% =23.08%

24 - 26                 9                 9/39 = 0.2308             0.2308 × 100% =23.08%

Class           Frequency     Relative frequency         Percent frequency

12 - 14                  2                  0.0513                          5.13%

15 - 17                  8                  0.2051                          20.51%

18 - 20                 11                 0.2821                          28.21%

21 - 23                  9                 0.2308                          23.08%

24 - 26                 9                 0.2308                          23.08%

Answer:

f(3)=2

Step-by-step explanation:

To find f(3), we simply need to find the ordered pair at x=3.

From the graph, we can see that the ordered pair at x=3 is (3,2).

Thus, f(3)=2.

And we're done!

Answer:

probability of randomly selecting an employee who is female and under the age of 25= 0.15

In percentage= 15%

Step-by-step explanation:

There are 300 female employees. There are 80 employees who are under the age of 25

Probabilty of choosing a female employees= 300/400

Probabilty of choosing a female employees= 0.75

Probabilty of choosing an employees under the age of 25

= 80/400

Probabilty of choosing an employees under the age of 25

= 0.2

probability of randomly selecting an employee who is female and under the age of 25= 0.2*0.75

probability of randomly selecting an employee who is female and under the age of 25= 0.15

In percentage= 0.15*100

In percentage= 15%
