9 is what percent of 45?

Answer:

Step-by-step explanation:

Given

f(x) = 4x + 7

so

f(a + h) = 4(a + h) + h

          = 4a + 4h +h

          = 4a + 5h

f(a) = 4a + 7

now by the question

[tex]\frac{f(a+h) - f(a)}{h}\\=\frac{4a + 5h - 4a + 7}{h}\\=\frac{ 5h + 7}{h} \\= \frac{5h}{h} + \frac{7}{h} \\= 5 +\frac{7}{h}[/tex]

hope it helps :)

Answer:

(-3,3)

Step-by-step explanation:

Using elimination:

Multiply the first equation by 8 and the second by 5 which equals

40x+56y=48

-40-60y=-60

Now you add them together

40x+(-40x)=0 so that crosses out

56y+(-60y)= -4y

48+(-60)=-12

You now have -4y=-12

Divide by -4

y=3

Now plug in y to any of the equations

5x+7(3)=6

5x+21=6

Subtract 21 from both sides

5x=-15

Divide by 5

x=-3

Your final solution is (-3,3)

Answer:7

Step-by-step explanation: 3 1/4 is equal to 13/4. When dividing fractions, you switch the numerator and denominator in the second fraction and change the symbol to a multiplication symbol. You then multiply straight across and then divide the top number by the bottom number. The whole number is how many times you can divide it equally

The number of ways Natalie has to choose outfits for her first day school is 28 ways.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

Given that, Natalie is trying to pick out an outfit for the first day of school. She can choose from 7 pairs of pants, 2 t-shirts, and 2 pairs of shoes.

Let 7 pairs of pants be P1, P2, P3, P4, P5, P6 and P7.

Let 2 t-shirts be T1 and T2

Let 2 pairs of shoes be S1 and S2

Now,

1) P1, T1, S1                                      

2) P1, T2, S2

3) P2, T1, S1

4) P2, T2, S2

5) P3, T1, S1

6) P3, T2, S2

7) P4, T1, S1

8) P4, T2, S2

9) P5, T1, S1

10) P5, T2, S2

11) P6, T1, S1

12) P6, T2, S2

13) P7, T1, S1

14) P7, T2, S2

15) P1, T1, S2                                      

16) P1, T2, S1

17) P2, T1, S2

18) P2, T2, S1

19) P3, T1, S2

20) P3, T2, S1

21) P4, T1, S2

22) P4, T2, S1

23) P5, T1, S2

24) P5, T2, S1

25) P6, T1, S2

26) P6, T2, S1

27) P7, T1, S2

28) P7, T2, S1

Other way = 7×2×2

= 28 ways

Therefore, the number of ways is 28 ways.

The amplitude of the function is the range A = 3

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the amplitude of the function be represented as A

Now , the value of A is

The range of the function = Amplitude x 2

And , Amplitude of the function A = | max - min | / 2

On simplifying , we get

A = | -4 - 2 | / 2

A = 6/2

A = 3

Therefore , the value of A is 3

Hence , the amplitude is A = 3

Answer:

m = 4

Step-by-step explanation:

ABCD ~ QRST, therefore, their corresponding side lengths brae proportional. This implies that:

10/m = 22.5/9

Cross multiply

m*22.5 = 9*10

22.5m = 90

Divide both sides by 22.5

m = 90/22.5

m = 4

Let the first angle = x

Let the second angle = 4x

Let the third angle = 2x + 5

All triangles have 180

Equation

x + 4x + 2x + 5 = 180

Solution

Begin by combining like terms

7x + 5 = 180

7x = 180 - 5

7x = 175

7x/7 = 175/7

x = 25

Answer

First angle = x    =          25

Second angle = 4x =    100

Third angle = 2x + 5 =    55

Answer:

?=52 or ?=-52

Step-by-step explanation:

Find the geometric mean:

?=sqrt(13*208)

?=sqrt(2704)

?=±52

So ? can be either 52 OR -52. Keep in mind that since we have an odd number of terms in the sequence, -52 is a possible missing term.

13*4=52, 52*4=208

13*-4=-52, -52*-4=208
