Find the solution set for -n^2-12n=0

Solution set is { 0 , -12 }

Step-by-step explanation:

• Solution set for an equation is the set in which the elements of the set satisfies the given equation !

Given equation :-

- n² - 12 n = 0

( Taking n common )

n ( -n - 12 ) = 0

• Either n = 0 , Or ( -n - 12 ) = 0

=> n = 0 , -n = 12

So, n = 0 and n = -12

Solution set is { 0 , -12 }

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
