Answers

Answer 1

Answer:

Step-by-step explanation:

4). This is an exponential function.

5). Let the equation of this function is,

    f(x) = a(b)ˣ

    Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,

    For (-1, 4),

    4 = a(b)⁻¹

    4 = [tex]\frac{a}{b}[/tex] --------(1)

    For (0, 6),

    6 = a(b)⁰

    a = 6

    From equation (1),

    4 = [tex]\frac{6}{b}[/tex]

    b = [tex]\frac{6}{4}[/tex] = 1.5

    Therefore, equation of the function will be,

    f(x) = 6(1.5)ˣ

6). Now the value of f(-4) will be,

    f(-4) = 6(1.5)⁻⁴

           = 1.185

using angle sum property

(x+12)= 35

x= 35-12

x= 23

Answer:

Angles in a triangle are sum up to 180 degrees.

35 + 110 + (x+12)=180

145+x+12=180

Model With Mathematics A photographer is
placing photos in a mat for a gallery show.
Each mat she uses is x in, wide on each side.
The total area of each photo and mat is
shown

Answers

Answer:

a. The possible dimensions of the total area are;

The width of the total area is (2·x + 8) inches

The length of the total area is (2·x + 10) inches

b. The dimensions of the photos are as follows;

The length of the photos are 10 inches

The width of the photos are 8 inches

Step-by-step explanation:

a. Given that the area, A = 4·x² + 36·x + 80

We get;

A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)

Therefore, the possible dimensions of the total area (photo + mat) are;

The width of the total area (photo + mat) = (2·x + 8) in.

The length of the total area (photo + mat) = (2·x + 10) in.

b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each

Therefore, we have the dimensions of the photos are as follows;

The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.

The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.

Find the slope

Answer:

slope = 4/11

Step-by-step explanation:

To find the slope, use delta y/ delta x

(4,6) (-7,2)

(2-6)/(-7-4)

(-4)/(-11)

slope = 4/11

Let m = slope

m = difference of y-values divided by the difference of x-values.

m = (2 - 6)/(-7 - 4)

m = -4/-11

m = 4/11

Jennifer deposits $1,000 into an account that is compounded monthly for 4 years. The account earns 7% interest. What is the ending balance in the account at the end of the 4 years (assuming no new deposits or withdrawals)? SHOW THE WORK PLEASE ​

Answers

9514 1404 393

Answer:

  $1,322.05

Step-by-step explanation:

The compound interest formula is appropriate.

  A = P(1 +r/n)^(nt) . . . principal P earning annual rate r for t years, compounded n times per year

You have P=1000, r=.07, n=12, t=4, so the balance is ...

  A = $1000(1+.07/12)^(12·4) ≈ $1000(1.322054)

  A = $1,322.05

Jennifer's ending balance is $1,322.05.
