A rhombus and a square have one and the same side of 6 cm. The area of the rhombus is 4/5 of the area of the square. Find the he

Arada [10]

You will find the area the square and then find out what 4/5 of that area is.

A = bh
6 cm x 6 cm
A = 36 square cm

4/5 of 36 square cm
4/5 x 36
28 4/5 square cm

The area of the rhombus is 28 4/5 square cm. Use this to solve for the height of the rhombus.

A = bh
28 4/5 = 6 x h
6 6
h = 4 4/5 cm

The height of the rhombus is 4 4/5 cm.

Use the function below to find f(4). f(x)= 1/3•4^x

kenny6666 [7]

Answer:

f(4) = 85 1/3 or 85.333...

Step-by-step explanation:

To find f(4), you must substitute 4 in place of x whenever x appears:

f(x) = $\frac{1}{3}$ * $4^{x}$

f(4) = $\frac{1}{3}$ * $4^{4}$

Next, simplify the exponent:

f(4) = $\frac{1}{3}$ * 256

Finally, multiply:

f(4) = 85 1/3 or 85.333...
