Answer:

Option B, [tex]x =[/tex] ± [tex]9.49[/tex]

Step-by-step explanation:

Step 1:  Add 90 to both sides

[tex]x^2 - 90 = 0[/tex]

[tex]x^2 - 90 + 90 = 0 + 90[/tex]

[tex]x^2 = 90[/tex]

Step 2:  Square root both sides

[tex]\sqrt{x^2} = \sqrt{90}[/tex]

[tex]x =[/tex] ± [tex]9.49[/tex]

Answer: Option B, [tex]x =[/tex] ± [tex]9.49[/tex]

Answer:

Total Platform = 128 ft^3

Step-by-step explanation:

Volume = Length * Width * Height

Left Volume: 2 ft * 4 ft * 3 ft = 24 ft^3

Mid Volume: 4 ft * 4 ft * 5 ft = 80 ft^3

Right Volume: 2 ft * 4 ft * 3 ft = 24 ft^3

Total Volume = 24 ft^3 + 80 ft^3 + 24 ft^3 = 128 ft^3

Answer:

v = [tex]108^{3}[/tex]

Step-by-step explanation:

I'd start with breaking the platform into two parts, the long flat rectangle and then the bit on top. You'll have to add these together at the end!

_________________

So part one: the long piece

formula: v = lwh

dimensions: 12, 3, 2

plug in: v = 12 * 3 * 2

solve: v = 72^3

_________________

part two: smaller rectangle on top ::

formula: v = lwh

dimensions: 4, 3, 3

plug in: v = 4 * 3 * 3

solve:v = 36*3

__________________

now, we add for the total of the entire shape!

final answer: 72 + 36 = 108^3

Answer:

47%

Step-by-step explanation:

First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.

Answer:

applying absolute law

if |u|=a, a>0 then u=a or u=-a

Answer:

Below!

Step-by-step explanation:

Let us consider that 16 + 4 and 2(2w+8) are equal. Then;

This equation can be solved in two ways. Listed below!

Method 1:

Let's simplify the left-hand-side of the equation.

Then, divide "2" both sides of the equation to open the parentheses.

Subtract 8 to both sides of the equation to isolate the variable (w) and it's coefficient.

Finally, divide 2 to both sides of the equation to isolate the variable (w).

Therefore, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Method 2:

Let's simplify the left-hand-side of the equation.

Then, simplify the distributive property to open the parentheses.

Subtract 16 to both sides of the equation to isolate the variable and it's coefficient.

Finally, divide 4 to both sides of the equation to isolate the variable (w).

As said in method 1, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

The leading term is the term with the highest degree, in this case, 5y³

The leading coefficient is the number in front of the leading term, 5

The constant term is a term with no variables contained, in this case, -1

Answer:

  C.  The equation has two valid solutions

Step-by-step explanation:

A rational equation like this is often solved by "cross-multiplying" to eliminate the fractions. When we do that, we get ...

  4(2x+10) = x(3x+1) . . . . . . . multiply both sides by (3x+1)(2x+10)

  3x² -7x -40 = 0 . . . . . . . . . . rearrange to standard form

  3x² -15x +8x -40 = 0 . . . . . . separate -7 into factors of 3(-40)

  3x(x -5) +8(x -5) = 0 . . . . . factor pairs of terms

  (3x +8)(x -5) = 0 . . . . . . . finish factoring

The zeros of these factors are not zeros of the original denominators, so neither of the solutions these give is extraneous.

  3x +8 = 0   ⇒   x = -8/3

  x -5 = 0   ⇒   x = 5

Answer:

y = -x/5 - 3

Step-by-step explanation:

Slope intercept form: y = mx + b

x + 5y = -15

5y = -15 - x

y = -15/5 -x/5

y = -x/5 - 3

Step-by-step explanation:

A. f(x) = -16x² +24x + 16

0 = -8(2x² - 3x - 2) ⇒ -8(2x + 1)(x - 2) = 0 ⇒ x = -1/2, 2

B. f'(x) = -32x + 24 ⇒ 0 = -8(4x - 3) ⇒ x = 3/4

f''(x) = -32 ⇒ f''(3/4) = -32 ⇒ concave down ⇒ maximum

f(3/4) = -16(9/16) + 24(3/4) + 16 = -9 + 18 + 16 = 25

By the second derivative test, the point (3/4, 25) is a maximum.

C. 1. Plot the intercepts. 2. Plug in points. 3. Draw the curve.

Answer:coesm

Step-by-step explanation:

The y intercept is the starting depth of the snow. In this case, it would be 18 inches (aka 1 ft + 6 inches aka 1.5 feet)

The y intercept is the starting value and it occurs when t = 0

S = -2t+18

S = -2(0)+18

S = 0+18

S = 18

At time t = 0, the depth of the snow is S = 18 inches. As t increases, the value of S will decrease.

Answer:

Equation: N = 2M, Shen needs to read 26 novels in 13 months

Step-by-step explanation:

Given : Shen needs to read 2 novels each month.

i.e. In One month , the number of novels read by Shen = 2

Let N be the number of novels Shen needs to read in M months.

Then , N = 2 M

Thus , the equation relating N to M : N = 2 M

If Number of months = 13 , then put M = 13 in the above equations , we get

N = 2(13) = 26

Hence, the number of novels he read in 13 months = 26.
