1. (g o f)(5) = 4
2. (f o g)(3) = 2
3. g(f(4)) = 2
4. f(g(2)) = 0
EXPLANATION
1) (g o f)(5)
It is important to note that:
(g o f)(5) = g ( f(5) )
And so, we will find the value of f(5), then use that to find g (f(5))
f(5) is the value of f(x) when x is 5.
=> f(5) = 3
=> g(f(5)) = g(3)
g(3) is the value of g(x) when x is 3.
=> g(3) = 4
Therefore, g(f(5)) = 4
2) (f o g)(3)
That is f(g(3))
g(3) is 4.
=> (f o g)(3) = f(4)
f(4) = 2
Therefore, (f o g)(3) = 2
3) g(f(4))
f(4) = 2
=> g(2) = 2
Therefore, g(f(4)) = 2
4) f(g(2))
g(2) = 2
=> f(2) = 0
Therefore, f(g(2)) = 0

The side of a cube is measured as 11.4 centimeters with a possible error of + - (positive and negative) 0.04 centimeters. Give an estimate for the possible error in the value of the volume of the cube.
Answer: _________ cubic cm
Answer:
The volume of a cube is given by the formula V = s^3, where s is the length of a side of the cube. In this case, the length of a side is 11.4 centimeters with a possible error of + - 0.04 centimeters.
To find the possible error in the value of the volume of the cube, we can use the formula for the maximum error in a product:
max error in V = |V| * (max error in s / s)
where |V| is the absolute value of the volume, and max error in s is the maximum possible error in the measurement of the side.
Substituting the given values, we get:
max error in V = |11.4^3| * (0.04 / 11.4)
max error in V = 538.516 * 0.00351
max error in V = 1.89 cubic centimeters (rounded to two decimal places)
Therefore, the estimate for the possible error in the value of the volume of the cube is 1.89 cubic centimeters

about travels in the following path. How far north did it travel? Round your answer to the nearest 10th of a mile
Answer:
19.1 miles
Step-by-step explanation:
The situation given represents a right triangle.
Thus, we would use trigonometric function to find how far north the boat travelled.
Let's represent how far the boat travelled north with "x".
Thus:
Reference angle = 23°
Opposite = x
Adjacent = 45 miles
Apply TOA:
Tan 23° = Opp/Adj
Tan 23° = x/45
Multiply both sides by 45
45 × Tan 23° = x
x = 45 × Tan 23°
x = 19.1013667
x = 19.1 miles (nearest tenth of a mile)

a. For this experiment, define the event that represents a "success
b. Explain why x is (approximately) a binomial random variable.
c. Give the value of p for this binomial experiment.
d. Find P(x-3) e. Find the probability that 2 or fewer of the 8 adults do not work during summer vacation.
Answer:
(a) The event that represents success here is the percentage of adults who do not work at all while on summer vacation.
(b) X is a binomial random variable.
(c) The value of p for this binomial experiment is 0.30 or 30%.
(d) P(X = 3) = 0.2541.
(e) The probability that 2 or fewer of the 8 adults do not work during summer vacation is 0.5518.
Step-by-step explanation:
We are given that in a school it is found that 30% of adults do not work at all while on summer vacation. In a random sample of 8 adults, let X represent the number who do not work during summer vacation.
Let X = the number of adults who do not work during summer vacation
(a) The event that represents success here is the percentage of adults who do not work at all while on summer vacation.
(b) The conditions required for any variable to be considered as a random variable is given by;
The experiment consists of identical trials.Each trial must have only two possibilities: success or failure.The trials must be independent of each other.So, in our question; all these conditions are satisfied which means X is a binomial random variable.
(c) The value of p for this binomial experiment is 0.30 or 30%.
(d) The above situation can be represented through binomial distribution;
\(P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,......\)
where, n = number of trials (samples) taken = 8 adults
r = number of success = exactly three
p = probability of success which in our question is % of adults who
do not work at all while on summer vacation, i.e; p = 0.25
SO, X ~ Binom(n = 8, p = 0.30)
Now, the probability that exactly 3 adults do not work at all while on summer vacation is given by = P(X = 3)
P(X = 3) = \(\binom{8}{3}\times 0.30^{3} \times (1-0.30)^{8-3}\)
= \(56 \times 0.30^{3} \times 0.70^{5}\)
= 0.2541
(e) The probability that 2 or fewer of the 8 adults do not work during summer vacation is given by = P(X \(\leq\) 2)
P(X \(\leq\) 2) = P(X = 0) + P(X = 1) + P(X = 2)
= \(\binom{8}{0}\times 0.30^{0} \times (1-0.30)^{8-0}+\binom{8}{1}\times 0.30^{1} \times (1-0.30)^{8-1}+\binom{8}{2}\times 0.30^{2} \times (1-0.30)^{8-2}\)

A garden table and a bench cost 670 combined. The garden table costs 80 less than the bench. What is the cost of the bench?
The bench costs $375, and the garden table costs $295. Together, they amount to $670, with the table being $80 cheaper than the bench.
Let the cost of the bench be x. Then the cost of the garden table is x-80. The sum of the costs of both items is $670. So we have the equation: x + (x-80) = $670.
Simplifying this, we get 2x - 80 = $670 + 80 2x = $750 x = $375. So the cost of the bench is $375. The garden table costs $375 - $80 = $295. A garden table and a bench cost $670 combined.
The garden table costs $80 less than the bench. To find the cost of the bench, we can use algebraic equations. Let the cost of the bench be x. Then, the cost of the garden table is x - 80.
The sum of both costs is $670. Using this information, we can form an equation: x + (x - 80) = $670. Simplifying, we get 2x - 80 = $670 + 80. Solving for x, we get x = $375.
Therefore, the cost of the bench is $375, and the cost of the garden table is $295.

←
The height of the object is at least 1000 feet from seconds to seconds.
Check the picture below.
so the parabolic path of the object is more or less like the one shown below in the picture, now this object has an initial of 1240 ft, as it gets thrown from the ski lift, so from 0 seconds is already higher than 1000 feet.
\(h=-16t^2+32t+1240\hspace{5em}\stackrel{\textit{a height of 1000 ft}}{1000=-16t^2+32t+1240} \\\\\\ 0=-16t^2+32t+240\implies 16t^2-32t-240=0\implies 16(t^2-2t-15)=0 \\\\\\ t^2-2t-15=0\implies (t-5)(t+3)=0\implies t= \begin{cases} ~~ 5 ~~ \textit{\LARGE \checkmark}\\ -3 ~~ \bigotimes \end{cases}\)
now, since the seconds can't be negative, thus the negative valid answer in this case is not applicable, so we can't use it.
So the object on its way down at some point it hit 1000 ft of height and then kept on going down, and when it was above those 1000 ft mark happened between 0 and 5 seconds.

The function
f(x) = 5sqrt(x + 13) + 5 has an inverse f ^ - 1 * (x) defined on the domain x < 5 Find the inverse. x >= - 13
The inverse function: \(f^{-1} (x) =\) \((\frac{x -5}{5} )^{2} -13\)
The inverse is defined on the domain x < 5 and x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5.
What is a function?A function is a relationship that exists between two sets of numbers, with each input from the first set, known as the domain, corresponding to only one output from the second set, known as the range.
Given function is; \(f(x) = 5\sqrt{(x + 13)} + 5\)
To find the inverse of the given function, we first replace f(x) with y:
⇒ \(y = 5\sqrt{(x + 13)} + 5\)
Subtract 5 from both sides:
⇒ \(y -5 = 5\sqrt{(x + 13)}\)
⇒ \(\frac{(y -5)}{5} = \sqrt{(x + 13)}\)
⇒ \((\frac{y -5}{5} )^{2} = x + 13\)
⇒ \((\frac{y -5}{5} )^{2} -13 = x\)
Now we have x in terms of y, so we can replace x with f⁻¹(x) and y with x to get the inverse function:
f⁻¹(x) = \((\frac{x -5}{5} )^{2} -13\)
The domain of the inverse function is x ≥ 5, because this is the range of the original function, and we were given that the inverse is defined on the domain x < 5. However, we must also exclude the value x = 5, because the denominator of the fraction \((\frac{x -5}{5} )^{2}\) becomes zero at this value. Therefore, the domain of f⁻¹(x) is x > 5.
We were given that x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5. Therefore, the domain of the inverse function becomes the range of the original function, and the range of the inverse function becomes the domain of the original function.

We can rewrite sin⁸x in terms of first powers of the cosines of multiple angles as:
sin⁸x = 1/128 (35 - 4cos²x + 40cos⁴x - 64cos⁶x + cos⁸x)
What is power reducing formula?Trigonometric functions raised to powers can be rewritten using double-angle, half-angle, and Pythagorean identities in power lowering formulas. Equations can be made simpler using them, and trigonometric expressions can be precisely determined.
We can use the power-reducing formulas to rewrite sin⁸x in terms of cosines of multiple angles as follows:
sin²x = 1 - cos²x (first power-reducing formula)
sin⁴x = (sin²x)² = (1 - cos²x)²
= 1 - 2cos²x + cos⁴x (second power-reducing formula)
sin⁶x = (sin⁴x)(sin²x)
= (1 - 2cos²x + cos⁴x)(1 - cos²x)
= 1 - 3cos²x + 3cos⁴x - cos⁶x (third power-reducing formula)
sin⁸x = (sin⁶x)(sin²x)
= (1 - 3cos²x + 3cos⁴x - cos⁶x)(1 - cos²x)
= 1 - 4cos²x + 6cos⁴x - 4cos⁶x + cos⁸x
Now we can substitute the expression for sin⁸x into the given expression and simplify it:
1/128 (35 - 56 cos2x + 28 cos4x - 8 cos6x + cos8x)
= 1/128 (35 - 56(2cos²x-1) + 28(4cos⁴x-3cos²x) - 8(8cos⁶x-8cos⁴x+cos²x) + cos⁸x)
= 1/128 (35 - 112cos²x + 56 + 112cos⁴x - 84cos²x - 64cos⁶x + 64cos⁴x - 8cos²x + cos⁸x)
= 1/128 (35 - 4cos²x + 40cos⁴x - 64cos⁶x + cos⁸x)
Therefore, we can rewrite sin⁸x in terms of first powers of the cosines of multiple angles as:
sin⁸x = 1 - 4cos²x + 6cos⁴x - 4cos⁶x + cos⁸x

TV=
All sides of a rhombus have equal measures, so TU = 8. Since a rhombus is a parallelogram, and the diagonals of a parallelogram bisect each other, WU = 10. The diagonals of a rhombus are also perpendicular, meaning they form right angles. Using the Pythagorean theorem, you can find the length of TX. (TX)^2 + (WX)^2 = (WT)^2. Substituting in known values, (TX)^2 + 25 = 64. Solving gives you TX = the square root of 39. TV is double the length of TX, so TV = 2 times the square root of 39.

Answer: The answer to your question is C. Brainliest?
Step-by-step explanation:
For the first square, we can multiply both the numerator and denominator by 5 to get an equivalent fraction with a denominator of 60:
2/12 = (2 x 5) / (12 x 5) = 10/60
For the second square, we can multiply both the numerator and denominator by 4 to get an equivalent fraction with a denominator of 60:
2/15 = (2 x 4) / (15 x 4) = 8/60
Now, we can add the two fractions:
10/60 + 8/60 = 18/60
Simplifying this fraction by dividing both numerator and denominator by 6, we get:
18/60 = 3/10
Therefore, the total shaded area in the diagram is 3/10 or 0.3 in decimal form.

For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the value "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.
We are given that the factored form of 30.8n+8.4 is a(11n+3).
To find the value of a, we can expand the product a(11n+3) and equate it to the given expression 30.8n+8.4.
Expanding a(11n+3), we get:
a(11n+3) = 11an + 3a
Equating this to 30.8n+8.4, we have:
11an + 3a = 30.8n + 8.4
We can factor out an "a" from the left-hand side:
a(11n + 3) = 30.8n + 8.4
Now we can see that this is the same as the given factored form, so we can equate the two expressions:
a(11n + 3) = a(11n + 3)
This is true for all values of a and (11n+3), so we can conclude that the value of "a" is simply 30.8 divided by (11n+3):
a = 30.8/(11n+3)

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 48 ft, find its length and width.
Formula we use,
→ P = 2(L + W)
Then the value of L and W is,
→ P = 2(L + W)
→ 48 = 2(2x + x)
→ 2(3x) = 48
→ x = 48/6
→ [ x = 8 ]
Then the width will be,
→ W = x = 8 ft
Hence, the width is 8 ft.
Now the length will be,
→ L = 2x = 2(8) = 16 ft
Therefore, the length is 16 ft.

Answer:
8 pounds of cheaper candy,
17.5 pounds of expensive candy
Step-by-step explanation:
Let's define some variables. Let's say the amount of pounds of candy that sells for $2.20/lb is x, and the $7.30 is y. Now we can write some equations!
x + y = 25.5
\(\frac{2.2x + 7.3y}{25.5} = 5.7\)
We can start substitution. We can say that x = 25.5 - y. Plugging this into our second equation, we get:
y = 17.5
Plugging this in, we find that:
x = 8.

(A) delta h(t) = 32
Step-by-step explanation:
Average rate of change delta h(t) is given by
\(delta \: h(t) = \frac{h(b) - h(a)}{b - a} \)
at t = 0, h(0) = 80
at t = 2, h(2) = -16(4) + 64(2) + 80 = 144
Plugging in the numbers
delta h(t) = (144 - 80)/(2 - 0)
= 32
