Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fxg)(-5). a. -59 b. 3 c. 26 d. -6

DedPeter [7]

Answer:

Step-by-step explanation:

The given functions are:

$f(x) = - 2x - 7$

and

$g(x) = - 4x + 6$

$(f \times g)(x) = f(x) \times g(x)$

$(f \times g)(x) = ( - 2x - 7)( - 4x + 6)$

When we plug in x=-5, we get:

$(f \times g)( - 5) = ( - 4 \times - 5 + 6)( - 2 \times - 5 - 7)$

$(f \times g)( - 5) = ( 20 + 6)( 10 - 7)$

$(f \times g)(5) = ( 26)( 3) =7 8$

Find cos B exactly if a = 15, b = 11, and angle Cis a right angle

astra-53 [7]

Answer:

Final answer is $\cos\left(B\right)=\frac{15}{\sqrt{346}}$ which is the last choice.

Step-by-step explanation:

In triangle ABC, we have been given a = 15, b = 11, and angle C is a right angle.

Now using those values, we need to find the exact value of cos B.

Apply Pythagorean formula:

$AB^2=AC^2+BC^2$

$AB^2=11^2+15^2$

$AB^2=121+225$

$AB^2=346$

$AB=\sqrt{346}$

Now apply formula of cos

$\cos\left(B\right)=\frac{BC}{AB}$

$\cos\left(B\right)=\frac{15}{\sqrt{346}}$

Hence final answer is $\cos\left(B\right)=\frac{15}{\sqrt{346}}$
