Answer:

8^1 = 8

So, x has to be 1/4 to make the exponent 1, and to make it equal to 8.

Let me know if this helps!

Instructions: Find the measure of the indicated angle to the nearest degree. ?

Y_Kistochka [10]

Answer:

? = 14

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan ? = 8/33

Taking the inverse tan of each side

tan ^-1 ( tan ?) = tan ^-1 ( 8/33)

? =13.62699

To the nearest degree

? = 14

A figure is a quadrilateral if and only if it is a polygon; biconditional true or false

Afina-wow [57]

I think the correct answer is false. A figure is not only a quadrilateral if and only if it is a polygon. A polygon can have three or more sides. A polygon is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit

A rectangle with vertices A(6, 0), K(0,0), L(0,9), and M(6, 9) is rotated around the x-axis. To the nearest tenth of a cubic uni

koban [17]

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL. From the given data

$KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.$

The volume of the cylinder is

$V_{cylinder}=\pi r^2\cdot H.$

Then

$V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.$

Answer:

x = 7

Step-by-step explanation:

The segment marked 6x is the midline of the triangle, so is half the length of the base.

6x = 1/2(84)

x = 42/6 = 7

The value of x is 7.
