If f(x)=x²-3 x+5 and g(x)=-2 x, find the following composition. (f°g)(2)
(f°g)(2)=__ (Simplify your answer.)
The value of the funciton of function f(g(x)) for x = 2 is that f(g(2)) is 33.
What is a function?The function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
As per the given function,
f(x) = x² -3x + 5 and g(x) = -2x
f(g(x)) = f(-2x)
Since the operation of f(x) is x²-3 x+5.
So, f(-2x) = (-2x)² - 3(-2x) + 5
f(g(x)) = 4x² + 6x + 5
The value of the combined function for x = 2 is
f(g(2)) = 4(2)² + 6(2) + 5
⇒ 16 + 12 + 5 = 33
Hence "The value of the funciton of function f(g(x)) for x = 2 is that f(g(2)) is 33".

A cylinder has a radius of 4 millimeters. Its volume is 200.96 cubic millimeters. What is the height of the cylinder?
Answer:
3.999 millimeters.
Step-by-step explanation:
To find the height of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
Given that the radius (r) of the cylinder is 4 millimeters and the volume (V) is 200.96 cubic millimeters, we can substitute these values into the formula and solve for the height (h).
200.96 = π(4²)h
200.96 = 16πh
To solve for h, we can divide both sides of the equation by 16π:
200.96 / (16π) = h
Using a calculator, we can calculate the approximate value of h:
h ≈ 200.96 / (16 × 3.14159)
h ≈ 3.999
Therefore, the height of the cylinder is approximately 3.999 millimeters.

Consider the following linear program.
Min 3A + 4B
s.t.
1A + 3B ≥ 9
1A + 1B ≥ 7
A, B ≥ 0
Answer:
Minimum z =22 at A =6, B=1
See the graph below variable A is on the horizontal axis and variable B on the vertical axis
Step-by-step explanation:
We can solve using the graphical method
Min z = 3A + 4B
s.t.
1A + 3B ≥ 9
1A + 1B ≥ 7
A, B ≥ 0
Draw two lines using the constraint equations
1A + 3B = 9
1A + 1B = 7
The feasible region for the inequality constraints is the region that satisfies all 4 constraints below
1A + 3B ≥ 9
1A + 1B ≥ 7
A, B ≥ 0
This is the heavily shaded region in the graph. The minimum will be at one of the corner points
There are three corner points on the graph
(0,7), (6,1) and (9,0)
Plug in these coordinate values with A being the first and B being second in the parentheses and see which set of values makes the objective function the minimum
Point (7,0) ==> z = 3(0) + 4(7) = 28
Point (6,1) ==> z = 3(6) + 4(1) = 22
Point (9,0) ==> z = 3(9)+4(0) = 27

There are 96 female staff in an office. If the ratio of male staff to female staff is 3:4, find the number of male staff.
Answer:60 male staff
Step-by-step explanation:
Ok, there are 96 female staff. The ratio of male to female is 3:4. We’re going to use a proportion which looks like this. 3/4 = x/96. X is a variable that takes the place of the male staff since we don’t know what it is. Now, the question is what do we do to get from 4 to 96. So 96/4 = 24, so 4 x 20 = 96. To keep this ratio equivalent whatever you do to the top you have to do to the bottom so 4 x 20 = 96 and 3 x 20 = 60. So there are 60 male staff.

Answer:
x = 30°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so you have ...
60° +2x +60° = 180°
2x = 60° . . . . . . . . .subtract 120° from both sides
x = 30° . . . . . . . . . . divide by 2
_____
Since the triangle is isosceles (base angles are congruent), the angle bisector is also an altitude that divides the triangle into congruent 30°-60°-90° triangles. The measure of the angle marked x is 30°.
1. Your parents took your family out to dinner. Your parents wanted to give the waiter a 22% tip. If the bill was $64.85, how much did your parents pay for dinner?
2. Michael took his son to the Magic game. Tickets for both of them cost $140 plus a $3.50 handling fee. He had to pay 6.5% sales tax. How much did Michael pay in total?
Answer:
1. ROUNDED 64.85 + 14.27 = 79.12
NOT ROUNDED 64.85 + 14.26 = 79.11
2. 143.50 + 9.32 = 152.82 not rounded
143.50 + 9.33 = 152.83 rounded
Step-by-step explanation:
1.
We need to find 22% of 64.85, and we do that by multiplying
64.85 x 0.22 = 14.267
Now we have 2 choices, if you round, the tip will be 14.27, but if you do not round, it will be 14.26. If you aren't sure, round the answer. 64.85 + 14.27 = 79.12 OR 64.85 + 14.26 = 79.11
2.
We will first solve for the total cost of the tickets before the sales tax
140.00 + 3.50 = 143.50
Then, we will calculate sales tax
143.50 x 0.065 = 9.32 not rounded
143.50 x 0.065 = 9.33 rounded
143.50 + 9.32 = 152.82 not rounded
143.50 + 9.33 = 152.83 rounded

Answer:
The interval from -12 to -7
The interval from 6 to 12.
Step-by-step explanation:
The equation is log(x + 9) + log(x 9) = log[(x + 9)(x 9)]. = log(x² − 81)
Here is the equation:
log(x² - 81) = 0.47712
This can be expressed in exponential form:
x² - 81 = 10^(0.47712)
x² = 81 + 3.02343
x² = 84.02343
x ≈ ± 9.1658
The answers are therefore x -9.1658 and x 9.1658.
These intervals are where these solutions occur:
The answer, x -9.1658, can be found in the range from -12 to -7.
- The answer x = 9.1658 is found in the range of 6 to 12.
The appropriate choices are:
- The range between -7 and -12; - The range between 6 and 12.

Triangles A B R and R C A share side R A. A line is drawn from point B to point C and intersects side A R at point P.
It is given that and are right angles, and . Since they contain right angles, ΔABR and ΔACR are right triangles. The right triangles share hypotenuse , and reflexive property justifies that . Since and , the transitive property justifies . Now, the hypotenuse and leg of right ΔABR is congruent to the hypotenuse and the leg of right ΔACR, so by the HL congruence postulate. Therefore, ________ by CPCTC, and bisects by the definition of bisector.
The BR is the perpendicular bisector of AC by CPCTC (corresponding parts of congruent triangles are congruent).
Based on the given information that angles ABR and ACR are right angles, and AB = AC, we can conclude that triangles ABR and ACR are right triangles.
Using the shared hypotenuse AR and the reflexive property, we can determine that side AB is congruent to side AC.
With this information, the transitive property allows us to conclude that angle BAR is congruent to angle CAR. Next, using the HL congruence postulate, we can prove that triangle ABR is congruent to triangle ACR.
This means that side BR is congruent to side CR, and angle BAC is bisected by line segment BR by the definition of bisector.

A certain virus infects one in every 300 people. A Test used to detect the virus in a person is positive 85% of the time if that prerson has the virus and 5% of the time if the person does not have the virus. This 5% result is called a false positive. Let "A" be the event the person is infected and "B" the event the person tests positive. Find the probability that a person has the virus given that they have tested positive find the P(A/B)= Round to nearest tenth of a % Don't include % sign.
The probability that a person has the virus given that they have tested positive find the P(A/B)=0.0045
We can use Bayes' theorem to find the probability that a person has the virus given that they have tested positive:
P(A | B) = P(B | A) * P(A) / P(B)
where P(B | A) is the probability of testing positive given that the person has the virus, P(A) is the prior probability of a person having the virus (1/300), and P(B) is the total probability of testing positive.
To find P(B), we can use the law of total probability, which states that:
P(B) = P(B | A) * P(A) + P(B | not A) * P(not A)
where P(B | not A) is the probability of testing positive given that the person does not have the virus. This is the false positive rate, which is 5% or 0.05 in this case. P(not A) is the complement of P(A), which is 299/300.
Substituting the values, we get:
P(B) = 0.85 * 1/300 + 0.05 * 299/300
= 0.059
Now we can plug in the values into Bayes' theorem:
P(A | B) = 0.85 * 1/300 / 0.059
= 0.0045 or 0.45%
Therefore, the probability that a person has the virus given that they have tested positive is 0.45% or 0.0045 (rounded to the nearest tenth of a percent).

has a circumference of 6 inches. (See Example 2.)
a. The apple has a density of 0.46 gram per cubic
centimeter. Find the mass of the apple.
b. The radius of the apple increases inch per week
for the next five weeks. How does the volume
change during the five-week period? Explain
a. The mass of the apple is approximately 33.879 grams.
b. The volume of the apple increases by approximately 1.454 cubic inches during the five-week period.
a. To find the mass of the apple, we need to calculate its volume first. The circumference of the apple can be used to determine its radius.
The formula for the circumference of a circle is C = 2πr,
where C is the circumference and r is the radius.
Rearranging the formula, we have r = C / (2π).
Plugging in the given circumference of 6 inches.
we get r = 6 / (2π) ≈ 0.955 inches.
Now, we need to convert the radius from inches to centimeters since the density is given in grams per cubic centimeter.
Since 1 inch is approximately 2.54 centimeters, the radius in centimeters is \(0.955 \times 2.54\) ≈ 2.427 cm.
Next, we can calculate the volume of the apple using the formula for the volume of a sphere: V = (4/3)πr³.
Plugging in the radius in centimeters, we get
V ≈ (4/3)π(2.427)³ ≈ 73.682 cm³.
Finally, we can find the mass of the apple by multiplying the volume by the density:
mass = volume \(\times\) density
= 73.682 cm³ \(\times\) 0.46 g/cm³
≈ 33.879 grams.
Therefore, the mass of the apple is approximately 33.879 grams.
b. The volume of a sphere increases with the cube of its radius.
Since the radius increases by 1/8 inch per week for five weeks, the change in radius would be\((1/8) \times 5 = 5/8 inch.\)
Now, let's calculate the change in volume during the five-week period. The formula for the volume of a sphere is V = (4/3)πr³.
Initially, the radius was 0.955 inches.
After five weeks, the radius would be 0.955 + 5/8 inches.
To compare the change in volume, we can calculate the new volume and find the difference:
Change in Volume = New Volume - Initial Volume
Initial Volume = (4/3)π(0.955)³
New Volume = (4/3)π(0.955 + 5/8)³
By subtracting the initial volume from the new volume, we can determine how the volume changes during the five-week period.
Please note that the exact calculation will depend on the precise values used for π and the measurements provided.

Talwar wants to invest R5800 at simple interest rate of 12,2% per annum. How many years will it take for the money to grow to R26100
It will take approximately 28.67 years for Talwar's investment of R5,800 to grow to R26,100 at a simple interest rate of 12.2% per annum.
To calculate the number of years it will take for Talwar's investment to grow to R26,100 at a simple interest rate of 12.2% per annum, we can use the formula for simple interest:
Simple Interest = Principal × Rate × Time
Given that the principal (P) is R5,800, the rate (R) is 12.2% (or 0.122 as a decimal), and the desired amount (A) is R26,100, we need to find the time (T) it will take. Rearranging the formula, we get:
Time = (Amount - Principal) / (Principal × Rate)
Plugging in the values, we have:
Time = (R26,100 - R5,800) / (R5,800 × 0.122)
= R20,300 / R708.6
