Solve the equation for x. -=7 Answer here

Leviafan [203]

Complete Question:

Solve the equation for x

$x-7=7$

Answer:

$x = 14$

Step-by-step explanation:

Given

$x-7=7$

Required

Solve for x

$x-7=7$

Add 7 to both sides

$x-7+7=7+7$

$x=7+7$

$x = 14$

Hence:

For $x-7=7$ , $x = 14$

What is the volume of the sphere below?

Sindrei [870]

Answer: Option C.

Step-by-step explanation:

The volume of a sphere can be calculated with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

You can observe in the figure that the value of the radius of this sphere is:

$r=4\ units$

Then you can substitute this radius into the formula $V=\frac{4}{3}\pi r^3$ .

Therefore, the volume of the sphere shown in the figure is:

$V=\frac{4}{3}\pi (4units)^3$

$V=\frac{256}{3}\pi \ units^3$

ASAP Find all solutions to the equation. 7 sin^2 x - 14 sin x + 2 = -5

matrenka [14]

Answer:

{-π/2, π/2}

Step-by-step explanation:

Rewrite this as:

7sin^2 x - 14sin x + 7 = 0. Reduce this result by dividing all terms by 7:

sin^2 x - 2sin x + 1

Temporarily replace "sin x" with y:

y^2 - 2y + 1 = 0

Solve this through factoring: (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1

Recalling that y = sin x, we write

sin x = ±1, whose solutions are sin x = 1 and sin x = -1

The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2

and so the solution set is {-π/2, π/2}
