Daisy making a memory box in the shape of the cube.The total volume is 216 cubic inches.What are the measurements of the length,

Lera25 [3.4K]

Answer:

The length, the width and the height of the box is 6 inches.

Step-by-step explanation:

Given:

Daisy making a memory box in the shape of the cube.

The total volume is 216 cubic inches.

Now, to find the length, width and height of the cube.

Volume of cube = 216 cubic inches.

As, the sides of the cube are having same length.

Thus, the measurements of length, width and height of the cube are same.

Now, to get the side of the cube we put formula:

$Volume=(side)^3\\\\216=(side)^3$

Using cube root on both sides:

$6=side\\\\Side=6\ inches.$

Therefore, the length, the width and the height of the box is 6 inches.

cos (x/2) = -sqrt2/2 in (0,360) looking for two values ?? Can someone please help me I can’t seem to figure out how to solve thi

ValentinkaMS [17]

Answer:

135° and 225°

Step-by-step explanation:

basically you want to find the value of x between 0 and 360 in this equation

cos x/2 = -(√2)/2

assume x/2 as n, so

cos n = -(√2)/2

n = 45°

then remember the quadrant system

0-90 1st quadrant, all is POSITIVE

90-180 2nd quadrant, only SIN has positive value

180 - 270 3rd quadrant, only TAN has positive value

270 -360 4th quadrant, only COS positive here.

so if you try to find negative value look into 2nd and 3rd quadrant that related 45° to x-axis (0°or 180°)

so the value of x is

180 - 45 = 135° (2nd quadrant) and

180 + 45° = 225° (3rd quadrant)

Answer:

m = $\frac{-3}{4}$

Step-by-step explanation:

We are given two points ( -3, 1 ) and ( 1, -2).

The slope formula is m = $\frac{rise}{run}$ = $\frac{y2 - y1}{x2 - x1}$

So, we have $\frac{(-2)-(1)}{(1)-(-3)}$ = $\frac{-3}{1+3}$ = $\frac{-3}{4}$
