Mathematics
1 answer:
Vanyuwa [196]3 years ago

We need to apply trigonometry for easy calculations.

Let Z represent the ramp.

sin x = wall divided by the ramp

Let x = 7°.

sin 7° = 2.5/Z

We now solve for Z.

Z = 2.5 ÷ sin 7°

Z = 20.5137726212

We round off to the nearest tenth of a foot. This means to round off to the ones place.

Z = 21 feet

Done.

G(x) = 4x2 – 3x + 2, find g(2a).
S_A_V [24]

Answer:

g(2a) = 16a^2 - 6a + 2

Step-by-step explanation:

Replace every occurrence of x in g(x) = 4x^2 – 3x + 2 with (2a); it's best to use parentheses here.

Then g(2a) = 4(2a)^2 - 3(2a) + 2

                  =  4(4a^2) - 6a + 2

                   =  16a^2 - 6a + 2 (answer)
