How do I solve radical equations?​

Answers

Answer 1
radical equation is solved by simply squaring or cubing both sides of the equation. For example:
(2x + 9) =5
(2x + 9)^2 =5^2

Then, continue to isolate the variable:
2x+9=25
2x + 9 - 9 = 25 -9
2x/2 = 16/12
X=8

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?

Answers

Answer:

volume = 13500 [tex]cm^{3}[/tex]

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = [tex]\frac{lwh}{3}[/tex]

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = [tex]\frac{30*30*45}{3}[/tex]

            = [tex]\frac{40500}{3}[/tex]

            = 13500

volume = 13500 [tex]cm^{3}[/tex]

The volume of the pyramid is 13500 [tex]cm^{3}[/tex].

The volume of the square-based pyramid is [tex]13500cm^3[/tex]

The volume of a pyramid is given by

[tex]V=\dfrac{Ah}{3}[/tex]

where

[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]

The area of the square base, [tex]A[/tex], is calculated as follows

[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]

substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume

[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]

Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]

If a circle has a diameter of 23 inches, then the radius will be

Answers

Answer:

11.5 in

Step-by-step explanation:

The radius is half the diameter

23/2=11.5

If a circle has a diameter of 23 inches, then the radius will be 12.5 inches.

What is the relation between the radius and the diameter of the circle?

The radius is half of the diameter of the circle, for calculating radius we can divide the diameter of the circle by 2.

Given that,

The diameter of the circle is equal to 23 inches.

d = 23 inches

It is known that,

The radius is half of the diameter of the circle,

so it can be written in the form expression as:

r  = D/2

D = 23 inches

r  = 23/2

  =  12.5 inches

Hence, the radius of the circle 12.5 inches.

The population of a town is 132,00. The population increases 4% a year. What will be the population in 8 years?

Answers

9514 1404 393

Answer:

  180,651

Step-by-step explanation:

Each year, the population is multiplied by the factor 1 + 4% = 1.04. After 8 years, it will have been multiplied by that factor 8 times. We indicate repeated multiplication like that using an exponent.

  population in 8 years = 132,000 × 1.04^8 ≈ 180,651

Solve the equation below for x in terms of a 4(ax+3)-3ax=25+3a

Answers

Answer:

x = (13 + 3a) / a

Step-by-step explanation:

Given equation:

4(ax+3) - 3ax = 25 + 3a

Open parenthesis

4ax + 12 - 3ax = 25 + 3a

Collect like terms

4ax - 3ax = 25 + 3a - 12

Simplify

ax = 13 + 3a

x = (13 + 3a) / a

4(ax+3) - 3ax = 25 + 3a is equivalent to x = (13 + 3a) / a

what does the a in y=a(1+r)x represent?

Answers

Answer:

The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.

The "a" in the expression y = a (1+r)ˣ represents the initial amount.

What is the expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given, a exponential expression  y = a (1+r)ˣ

The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.

Therefore, the initial amount is been represented by "a" in the given expression.
