TiliK225 [7]

9514 1404 393

Answer:

59 cm

Step-by-step explanation:

The area is the product of length and width. Using the given numbers, we have ...

A = LW

4779 cm² = (81 cm)W

W = (4779 cm²)/(81 cm) = 59 cm

The width of the window is 59 cm.

Find the range of the function for the given domain. f(x) = 2x - 7 ; {-2, -1, 0, 1, 2}

Studentka2010 [4]

The domain is a discrete set. So we will have a discrete range.

The range is a set containing:

f(-2)=-11

f(-1)=-9

f(0) = -7

f(1) = -5

f(2) = -3

Range = {-11,-9,-7,-5,-3}

Find the cosine of R.

JulijaS [17]

Answer:

$cos(R) = \frac{\sqrt{15}}{5}$

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

$cos(R) = \frac{adjacent}{hypotenuse}$

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

$cos(R) = \frac{3}{\sqrt{15}}$

Multiply the numerator and denominator by √15 to rationalize.

$cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}$

$cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}$

$cos(R) = \frac{3\sqrt{15}}{15}$

$cos(R) = \frac{\sqrt{15}}{5}$
