Answer:

Step-by-step explanation:

This question really threw me at first, even after graphing the equation I still didn't believe the answer.

(8^1/3) ^2 = 4^x

8^2/3 = 4^x Any fractional power is a root function

x^1/2 = square of x or √x

x^ 1/3 is the is the cubic root of x or ∛x

My first thought was to multiply the 1/3 times 2 (the square).

It is more oblivious if you find the cubed of 8 and then apply the square

(∛8)² = 2² = 4 so 4 is equal to 4^x 4 = 4^x if x =1

What is the volume of this stack of blocks if each block measures 1 centimeter on each side ?

zlopas [31]

The volume of a cube is just cubing one side (1 times one times 1). So you just count up the cubes I guess!

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph.

dangina [55]

Answer:

Step-by-step explanation:

y=2x+4

slope=2

y- intercept=4

$slope=\frac{rise}{run}\\2=\frac{4}{run}\\run=\frac{4}{2}=2\\$

so draw a line through (0,2) and (2,8)

Answer:

1) $65\textdegree$

2) $44\textdegree$

3) $107\textdegree$

4) $82\textdegree$

Step-by-step explanation:

1) Since the whole angle is $180\textdegree$ , and to find the other angle, which is labeled as $x$ , you subtract $115\textdegree$ from $180\textdegree$ :

$180 - 115 = 65$

$x = 65\textdegree$

2) Since you already have two angle measures $46\textdegree$ and $90\textdegree$ , you add them up and subtract it from $180\textdegree$ to get the angle measure for $x$ :
