ANSWER

$\cos(y) = \frac{4}{5}$

EXPLANATION

From the mnemonics SOH-CAH-TOA.

We want to find the cosine of y

CAH means cosine ratio involves adjacent over the hypotenuse.

$\cos(y) = \frac{adjacent}{hypotenuse}$

From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.

$\cos(y) = \frac{64}{80}$

$\cos(y) = \frac{4}{5}$

A circle has a radius of length r. If you mark off an arc on the circle of length 2r what is the measurement of the angle that s

Inessa05 [86]

A full circle has a circumference of 2πr and an angle of 2π radians.

Set up a proportion:
2πr - 2π rad
2r - x rad

$2\pi r \times x = 2\pi \times 2 r \\
2\pi r x=4 \pi r \\
x=\frac{4 \pi r}{2 \pi r} \\
x=2$

The answer is D. 2 radians.

What is the product of -2x^3 + x -5 and x^3 – 3x?

lana66690 [7]

(-2x^3 +x -5) * (x^3 -3x)
= x^6*(-2*1) +x^4*(-2*-3 +1*1) +x^3*(-5) +x^2*(-3) +x(-5*-3)
= -2x^6 +7x^4 -5x^3 -3x^2 +15x

Kisachek [45]

Answer:

3 shirts, 6 shorts

Step-by-step explanation:

A total of $264 is spent during shopping on shirts and shorts

Each shirt costs $24

Each shorts cost $32

Therefore the quantity of shirts and shorts bought can be calculated as follows

24× 3= 72

32×6= 192

192+72= 264

Hence 3 shirts and 6 shorts were bought
