Answer:

a(b(5)) = 76

Step-by-step explanation:

Evaluate b(5) then substitute the value obtained into a(x)

b(5) = 5² = 25, then

a(25) = 3(25) + 1 = 75 + 1 = 76

<span>Data:
</span><span>Hypotenuse is 7.5
Opposite of angle x is 6</span><span>

Cosine = Side opposite (S.O) the angle on the hypotenuse (h)

We have:

</span> $Cos (\alpha)x = \frac{S.O}{h}$
$Cos (\alpha)x = \frac{6}{7.5}$
$\boxed{Cos (\alpha)x = 0.8}$

What is the value of (Negative 14 Superscript 0 Baseline) Superscript negative 2? Negative StartFraction 1 Over 196 EndFraction

Nookie1986 [14]

Answer:

1

Step-by-step explanation:

Assuming, we want to find the value of $((-14)^0)^{-2}$

Recall that: any non-zero number exponent zero is 1.

Using this property, we simplify our expression to $(1)^{-2}$ since $(-14)^0=1$

Now using the property of exponents: $a^{-n}=\frac{1}{a^n}$

This implies that: $1^{-1}=\frac{1}{1^2}=\frac{1}{1}=1$

The correct answer is 1
