Answer:

"x = 4.38, −0.38"

Step-by-step explanation:

The equation to solve is a quadratic:

-3(x-2)^{2}+17=0

We take -17 to the other side and divide by -3 and solve by taking square root and be sure to take + and - solutions:

-3(x-2)^{2}+17=0\\-3(x-2)^{2}=-17\\(x-2)^{2}=5.67\\x-2=+-\sqrt{5.67} \\x-2=+-2.38\\x=2.38+2=4.38\\x=-2.38+2=-0.38

Hence, the solutions are x = 4.38 and -0.38

I WILL AWARD BRAINLIEST!! PLEASE HELP!!
dimulka [17.4K]

Answer:

the absolute value inequality in the form |x-b|c that has the solution set x≤−9 or x≥−5. lol jk

Step-by-step explanation:

|x−b|=c

Since we need three conditions that need to be met, we will opt for presenting three different expressions as a solution.

Case 1

One solution: x=−9

One expression that satisfies this condition is

(c = 0, b = -9 )

|x + 9|=0

|-9 + 9|=0

Case 2

All numbers such that x≤5

The solutions that satisfy this case can be found in the attached picture below, (they were obtained with a mathematical solver.)

Case 3

All numbers such that x≤-14

i pretty sure this is it.

Marjorie needs to calculate how much water a cylindrical tank will hold. The tank is 9 feet high and has a diameter of 5 feet. H
aniked [119]

Answer:

The volume of the cylindrical tank is 176.625 cubic feet.

Step-by-step explanation:

Given : The tank is 9 feet high and has a diameter of 5 feet.

To find : Marjorie needs to calculate how much water a cylindrical tank will hold ?

Solution :

The volume of a cylinder is V=\pi r^2 h

The diameter is d=5 feet

The radius is r=\frac{d}{2}

r=\frac{5}{2}=2.5 feet.

The height is h=9 feet.

Substitute the value in the formula,

V=3.14\times (2.5)^2\times 9

V=3.14\times 6.25\times 9

V=176.625

The volume of the cylindrical tank is 176.625 cubic feet.
