5 0

Answer:

24a^2 + 3.

Step-by-step explanation:

Substitute 2a for x in the function:

f(2a) = 6(2a)^2 + 3

=  6 * 4a^2 + 3

= 24a^2 + 3.

Simplify the following radical expression :<br> 3√12 × 5√6
Hoochie [10]
3 \sqrt{12} *5 \sqrt{6} = 15 \sqrt{72}.

Simplifying the radical, we have <u />15 \sqrt{72} = 15*6 \sqrt{\frac{72}{6^{2}} } =90 \sqrt{2}, so our answer is 90 \sqrt{2}.

By using trigonometric relations, we will see that x = 9.97°.

<h3>How to find the missing angle?</h3>

First, we need to find the bottom cathetus of the smaller triangle, we will use the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Where:

  • θ = 26°
  • Adjacent cathetus = k
  • Opposite cathetus  = 55ft.

Replacing that we get:

Tan(26°) = 50ft/k

Solving this for k, we get:

k = 55ft/tan(26°) = 112.8 ft

Now, we can see that the longer triangle adds 200ft to this cathetus, so now we will have:

  • angle = x
  • opposite cathetus = 55ft
  • adjacent cathetus = 112.8ft + 200ft = 312.8ft.

Then we have:

Tan(x) = (55ft/312.8ft)

Using the inverse tangent function in both sides, we get:

x = Atan(55ft/312.8ft) = 9.97°
