Answer:

-3.5 or -7/2

Step-by-step explanation:

Pentagons have five sides, so 15x+35

15x+35=5

subtract 35

15x+35-35=5x-35

simplify

15x=5x-35

subtract 5x

15x-5x=5x-35-5x

simplify

10x=-35

divide by 10

$\frac{10x}{10}=\frac{-35}{10}$

simplify

$x=-\frac{7}{2}$ or also -3.5

Each face of a cube has an area of 400 cm2. what is the volume of the cube?

dimaraw [331]

A cube is a square shape, so both sides ( length and width) of a face would be the same.

Find the length of the side by finding the square root of the area of the face:

Length = √400 = 20 cm.

Volume is Length x Width X height.

Volume = 20 x 20 x 20 = 8,000 cm^3

Serjik [45]

We know that:

limx→0 sin(x)/x = 1.
and
cscx = 1/sinx
so,
<span>limx→0 x/sinx = 1</span>

50 POINTS!!! <br> Which function is shown on the graph below?<br> See photo

Volgvan

Answer:

C. $y=\sqrt{2x-6}+1$

Step-by-step explanation:

From the graph of the function, we can see that the domain of the function is $x\ge 3,$ the range of the function is $y\ge 1.$

Consider the parent function $y=\sqrt{x}.$

The domain of this function is $x\ge 0,$ the range of this function is $y\ge 0.$

The function $y=\sqrt{2x-6}+1$ has

the domain

$2x-6\ge 0\\ \\2x\ge 6\\ \\x\ge 3$

and the range

$y\ge 0+1\\ \\y\ge 1$

All other options have different domain, or the range, or both the domain and the range.
