The functions f and g are defined as follows.
f(x)= 1/(x+2)
g(x)= square root of: (x-1)
(a)
State which value of x cannot be included in the domain of f.
(b)
Find the inverse of g(x)
(c) Calculate fg(10)
Answer:
x != -2, x^2 + 1, 1/5
Step-by-step explanation:
(a) It can be understood that nothing can divide 0
thus denominator cannot be 0 meaning x cannot be -2.
(-2 + 2) = 0
(b) y = sqrt(x-1)
inverse meaning we make x the subject
square both sides
y^2 = x - 1
y^2 + 1 = x
inverse = x^2 + 1
(c) composite function:
pass g(10) as domain of f
g(10) = 3, f(3) = 1/(5) = 1/5
Write a general formula to describe the variation:
x varies inversely with the square root of y; x = 6 when y = 64.

The diagram shows the ratio of trees Maeve plants to the trees she harvests.
Thank u
Answer:
Wednesday is 45 to 18.
Thursday is 55 to 22
Step-by-step explanation:
Wednesday: The original ratio was 5 to 2 And the info tells us that the new ratio is ? to 18. To find the first part we have to find how we got from 2 to 18. 2 * 9 = 18. So to find out the first part you do 5 * 9 = 45. We multiply 5 because Thats the original 1st part. We multiply 9 because that's how we got to 18 in the 2nd part. So the answer is 45 for Wednesday.
Thursday: The original ratio was 5 to 2 And the info tells us that the new ratio is 55 to ?. To find the first part we have to find how we got from 5 to 55. 5 * 11 = 55. So to find out the 2nd part you do 2 * 11 = 55. We multiply 2 because That's the original 2nd part. We multiply 11 because that's how we got to 55 in the 1st part. So the answer is 22 for Thursday.
Answer:
The answer is 45 to 18 and 55 to 22 hope this helps

What is the area, in terms of A, of the shaded
region?
Answer:
[tex] \frac{80\pi} [/tex]
Step-by-step explanation:
Area of shaded region = θ/360 × πr²
Where,
θ = 360 - 60 = 300°
r = 8
Plug in the values
[tex] area = \frac{300}{360} * \pi * 8² [/tex]
[tex] = \frac{5}{6} * \pi * 64 [/tex]
[tex] = \frac{5*\pi*64}{6} [/tex]
[tex] = \frac{5*\pi*16} [/tex]
[tex] = \frac{80\pi} [/tex]

Step-by-step explanation:
A has a coordinate of 3.75 because 2.5 × 1.5 = 3.75 and 3.75 is greater then -3
B has a coordinate of 7 because -3.5 × -2 = 7 and 7 is greater then -3
C has a coordinate of 0 because 0 x 0 = 0 and 0 is greater then -3

Solve 1= X^2+3x-16/X^2-6x+8
Answer:
x=1.816298 or x=−1.162524
Step-by-step explanation:
Step 1: Multiply both sides by x^2.
x2=x4−3x3+8x2−16
x2−(x4−3x3+8x2−16)=x4−3x3+8x2−16−(x4−3x3+8x2−16)(Subtract x^4-3x^3+8x^2-16 from both sides)
−x4+3x3−7x2+16=0
(Use quartic formula)
x=−1.162524,1.816298
Check answers. (Plug them in to make sure they work.)
x=1.816298(Works in original equation)
x=−1.162524(Works in original equation)
An 8 kg box is at rest and is pushed for 10 m with a 60 N force. If it's accelerated to 10 m/s, calculate the efficiency of the force.
Answer:
2/3
Step-by-step explanation:
The work done on the box is ...
Fd = (60 N)(10 m) = 600 N·m = 600 J
The amount of energy the box has as a result is ...
KE = 1/2mv² = (1/2)(8 kg)(10 m/s)² = 400 kg·m²/s² = 400 J
The ratio of box energy to energy input is ...
η = (400 J)/(600 J) = 2/3 . . . ≈ 66.7%

Two customers took out car loans from a bank.
Marcus took out a 5-year loan for $10,000 and paid 4.7% annual simple interest.
Gianna took out a 6-year loan for $10,000 and paid 4.5% annual simple interest.
What is the difference between the amounts of interest Marcus and Gianna paid for their car loans?
Enter your answer in the box.
The difference between the amounts of interest Marcus and Gianna paid for their car loan should be $350.
Calculation of the difference;
For Marcus, the interest be like
= ($10,000) (4.7%) (5)
= $2,700
And, for gianna, the interest be like
= ($10,000) (4.5%) (6)
= $2,350
So, the difference is
= $2,700 - $2,350
= $350
hence, The difference between the amounts of interest Marcus and Gianna paid for their car loan should be $350.

[tex]\Large\boxed{\sf I=Prt}[/tex]
where:
I = total interest accruedP = principalr = interest rate (in decimal form)t = time (in years)Marcus
Given:
P = $10,000r = 4.7% = 0.047t = 5 years⇒ Interest = 10000 × 0.047 × 5

What is the equation of the inverse y = x^2 + 4?
Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Enter the correct answer.
Answer:
f(x) = [tex]\frac{1}{2}x+4[/tex]
Step-by-step explanation:
Let the equation of the function is,
f(x) = mx + b
Here, m = slope of the line
b = y-intercept
From the graph attached,
y-intercept 'b' = 4
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]\frac{1}{2}[/tex]
Therefore, equation of the function representing the graph will be,
f(x) = [tex]\frac{1}{2}x+4[/tex]

The average value of a function f over the interval [−2,3] is −6 , and the average value of f over the interval [3,5] is 20. What is the average value of f over the interval [−2,5] ?
Answer:
The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].
Step-by-step explanation:
Let suppose that function [tex]f[/tex] is continuous and integrable in the given intervals, by integral definition of average we have that:
[tex]\frac{1}{3-(-2)} \int\limits^{3}_{-2} {f(x)} \, dx = -6[/tex] (1)
[tex]\frac{1}{5-3} \int\limits^{5}_{3} {f(x)} \, dx = 20[/tex] (2)
By Fundamental Theorems of Calculus we expand both expressions:
[tex]\frac{F(3)-F(-2)}{3-(-2)} = -6[/tex]
[tex]F(3) - F(-2) = -30[/tex] (1b)
[tex]\frac{F(5)-F(3)}{5-3} = 20[/tex]
[tex]F(5) - F(3) = 40[/tex] (2b)
We obtain the average value of [tex]f[/tex] over the interval [tex][-2, 5][/tex] by algebraic handling:
[tex]F(5) - F(3) +[F(3)-F(-2)] = 40 + (-30)[/tex]
[tex]F(5) - F(-2) = 10[/tex]
[tex]\frac{F(5)-F(-2)}{5-(-2)} = \frac{10}{5-(-2)}[/tex]
[tex]\bar f = \frac{10}{7}[/tex]
The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].

ANSWER ASAP The questions on a multiple-choice test each have 5 answer choices.
Which of the following models could you use to simulate the
outcome of guessing the correct answer?
F. spinning a spinner with five equal sections
G. flipping a coin five times
H. spinning a spinner with four equal sections
I. rolling a number cube labeled one through six five times
Answer:
F, spinning a spinner with five equal sections
Step-by-step explanation:
The probability of something is (the ways to acheive the wanted outcome / all possible situations)
For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50
Now, onto the problem.
There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.
F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.
G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.
H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.
I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.

Answer:
(a) The width is 40 inches
(b) It will not
Step-by-step explanation:
Given
[tex]D = 50[/tex] -- Diagonal
Solving (a): H = 30 --- (height).
Find the width (W)
To do this, we make use of Pythagoras theorem
[tex]D^2 = H^2 + W^2[/tex]
This gives:
[tex]50^2 = 30^2 + W^2[/tex]
[tex]2500 = 900 + W^2[/tex]
Collect Like Terms
[tex]W^2 = 2500 - 900[/tex]
[tex]W^2 = 1600[/tex]
Take square roots
[tex]W = 40[/tex]
Solving (b): Will it fit into a 30 in wide cabinet?
In (a) above, we calculated the width of the TV to be 40 inches
This implies that, the width is greater than the width of the cabinet.
So, it will not fit in
