Answer 1

Replace the range for f(x)

So...

0=4-2x

x=2

4=4-2x

x=0

8=4-2x

x=-2

A painted water tower is shown. What percent of the surface area of the water tower (not including the surface underneath the tower) is green? Round your answer to the nearest tenth of a percent.

Answers

Answer:

43.6%

Step-by-step explanation:

curved surface area (green) is found by circumference multiply by height

[tex]\pi[/tex] x d x h = [tex]\pi[/tex] x (15 x 2) x 12 = 360[tex]\pi[/tex]

total surface area is

blue circle + total curved surface area (blue + green)

= [tex]\pi[/tex][tex]r^{2}[/tex] + 15(2)(8)[tex]\pi[/tex] + 360[tex]\pi[/tex]

= [tex]15^{2}[/tex][tex]\pi[/tex] + 240[tex]\pi[/tex] + 360[tex]\pi[/tex]

= 825[tex]\pi[/tex]

percentage = 360[tex]\pi[/tex]/825[tex]\pi[/tex] x 100%= 22/55 x 100% = 43.63

Using the order of operations, what is the last calculation that should be done to evaluate 4(8 − 6)52 − 6 ÷ (−3)?
4(8 − 6)52 − 6 ÷ (−3)
4(2)52 − 6 ÷ (−3)
4(2)(25) − 6 ÷ (−3)
200 − 6 ÷ (−3)
200 − (−2)

Answers

Answer & Step-by-step explanation:

4(8 - 6)52 - 6 ÷ (-3)

First, subtract 6 from 8

4(2)52 - 6 ÷ (-3)

4(2)(52) - 6 ÷ (-3)

Multiply 2 by 52

416 - 6 ÷ (-3)

Divide -6 by -3.

416 + 2

Add 2 to 416

418

So, your evaluated answer would be 418.

Answers

Answer:

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

Step-by-step explanation:

Points:

(7, 10) and (7, 20)

Slope-intercept form:

y= mx+b

Slope is:

m= (y2-y1)/(x2-x1)= (20-10)/(7-7)= 10/0,

denominator of the fraction is zero, we can't divide by zero, so this line has no slope

----------

It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.

no, numerator is not zero

What is the decay factor in y = 760(0.75)3?

Answers

Answer:

Decay factor is 0.75.

Step-by-step explanation:

The given function is  

[tex]y=760(0.75)^3[/tex]     ...(1)

The general form of exponential decay function is  

[tex]y=a(1-r)^t[/tex]    ...(2)

where, a is initial amount, t is the time period, r is decay rate and (1-r) is the decay factor.

On comparing (1) and (2), we get

[tex]a=760, t=3, (1-r)=0.75[/tex]

Therefore, the decay factor is 0.75.

Examine the following gizmo problem and choose the best answer

Answers

Answer:

C. The answer is correct

Step-by-step Explanation:

One of the rules that applies when simplifying radical expressions, is that, only like radicals can be added together or subtracted from each other. In other words, the radicand, which is the number inside the "√" must be the same for two or more radicals to be added together or subtracted from each other.

In the expression given in the question, step 1 and step 2 are correct, as well as the final answer.

The final answer is correct because only like radicals can be added as 3√19 and 8√38 are unlike radicals. Their radicands, √19 and √38, are not the same, hence, the radicals do not need to be added.

The answer "3√19 + 8√38" is correct.

If f(x) = x^2 - 2x and g(x) = 6x + 4, for what value of x does (f + g)(x) = 0?

Answers

Answer:

x = -2

Step-by-step explanation:

[tex]f(x) =x^2 -2x\:\: and \:\: g(x) = 6x + 4\\(f+g)(x) = f(x) + g(x) \\(f+g)(x) = x^2 -2x+ 6x + 4\\(f+g)(x) = x^2+4x + 4\\(f+g)(x) = (x+2)^2\\ 0 = (x+2)^2...[\because (f+g)(x) =0]\\0 = x+2\\\therefore x = -2[/tex]

Answer:

x = -3 + √5 and x = -3 - √5

Step-by-step explanation:

Combine f and g:

f = x^2  -2x

+g =        6x  + 4

-------------------------

(f + g)(x) = x^2 + 6x + 4

Set this result = to 0 and solve for x:

By completing the square, we get:

y = x^2 + 6x + 9 - 9 + 4, or

y = (x + 3)^2 - 5 = 0

Thus, (x + 3)^2 = 5, and:

x + 3 = ±√5, or

x = -3 + √5 and x = -3 - √5
