we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

How to find the dimensions of the large rectangle?

First, we know that the large rectangle is the smaller rectangle rescaled, with a scale factor k = 4.

This means that each dimension of the smaller rectangle must be multiplied by 4 to get the correspondent dimension on the larger rectangle.

The dimensions of the smaller rectangle are:

l₁ = 12in

w₁ = 8in

Then the correspondent dimensions of the large rectangle are:

l₂ = 4*12in = 48 in

w₂= 4*8in = 32in

Now, the area of the large rectangle is given by the product between the two dimensions, we will get:

A₂ = 48in*32in = 1,536 in^2

Then, we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

1) $400 interest is earned on a principal of $2,000 at a simple interest rate of 5%
Kitty [74]

Answer:

4 years

Step-by-step explanation:

I = $ 400

R = 5%

P =$ 2000

I = Prt

400 = 2000 * \frac{5}{100} * t

400 = 20 * 5 * t

400 = 100 t

\frac{400}{100}=t

t = 4 years

Use Synthetic substitution to find f(3) and f(-4) for f(x)=x^4-8x-11
brilliants [131]

Answer:

46 and 277

Step-by-step explanation:

Given

f(x) = x^{4} - 8x - 11 ← substitute x = 3, x = - 4 into f(x)

f(3) = 3^{4} - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46

f(- 4) = (-4)^{4} - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277

Seventeen members of Tim's family are going to an amusement park during the week of their family reunion. Adult tickets cost $34
baherus [9]

Answer:

c.

Step-by-step explanation:

Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.

We have $34x + $31.5(17 - x) = $558.

$34x + $31.5(17 - x) = $558

$34x + $535.5 - $31.5x = $558

$2.5x = $22.5

x = 9

Hence the answer is c.
