What is the cosine of angle F A. 4/5 B. 3/4 C. 5/4 D. 3/5

saveliy_v [14]

Answer: option D

Step-by-step explanation:

Remember the cosine identity:

$cos\alpha=\frac{adjacent}{hypotenuse}$

Given the right triangle DFE shown in the image, you can identify that the adjacent side and the hypotenuse for the angle F of this triangle are:

$adjacent=15\\hypotenuse=25$

Now you can substitute values into $cos\alpha=\frac{adjacent}{hypotenuse}$ and then reduce the fraction.

THerefore you get: $cos(F)=\frac{15}{25}\\\\cos(F)=\frac{3}{5}$

What is the answer to this?

konstantin123 [22]

Answer:

$\huge\boxed{-6}$

Step-by-step explanation:

Since we know the values of a, b, and c, we can substitute them into our expression and get the value.

$-2b + | -3c + a |\\\\-2(6) + |-3(-3) + -3 |$

A negative multiplied by a negative gets us a positive.

$-2(6) + |9 + -3 |$

Adding a negative is the same as subtracting a positive.

$-2(6) + |9 -3 |\\-2(6) + 6$

$-2 \cdot 6 = -12\\\\-12+6\\\\-6$

Hope this helped!

Find the volume of a cube with a side length of 4r3s2.

andrey2020 [161]

Answer:

V = 64 r^(9) * s^(6)

Step-by-step explanation:

The volume of a cube is given by

V = s^3 where s is the side length

V = ( 4r^3s^2) ^3

We know that ( ab) ^c = a^c * b^c

V = 4^3 * r^3^3 * s^2^3

V = 64 * r^3^3 * s^2^3

We know that a^b^c = a^(b*c)

V = 64 r^(3*3) * s^(2*3)

V = 64 r^(9) * s^(6)
