What is the inverse of the function f(x) = 4x + 8?
Answer:
h(x) = (1/4)x - 2 which is choice A
Step-by-step explanation:
Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.
f(x) = 4x+8
y = 4x+8
x = 4y+8
x-8 = 4y
4y = x-8
y = (x-8)/4
y = x/4 - 8/4
y = (1/4)x - 2
h(x) = (1/4)x - 2

A publisher reports that 55% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 280 found that 51% of the readers owned a laptop. Make the decision to reject or fail to reject the null hypothesis at the 0.05 level.
Answer:
We fail to reject the null hypothesis, we accept H₀
Step-by-step explanation:
Population proportion p₀ = 55 % p₀ = 0,55
Sample size n = 280
Sample mean p = 51 % p = 0,51 q = 0,49
n*p and n*q are both bigger than 10 therefore we can approximate the binomial distribution to a normal distribution
Test Hypothesis
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p ≠ p₀
Significance level is α = 0,05 but we have a two-tail test then
α/2 = 0,025
z(c) = - 1,96
Computing z(s)
z(s) = ( p - p₀ ) / √(p*q)/n
z(s) = ( 0,51 - 0,55 ) / √(0,51*0,49)/280
z(s) = - 0,04 * 16,73 / 0,5
z(s) = - 1,34
Comparing
z(s) and z(c)
- 1,34 < - 1,96
| z(s) | < | z(c)|
Then z(s) is in the acceptance region, we accept H₀

W. Altus is climbing 3000 ft to the top of a mountain. The temperature was
60°F when he started, but he expects it to drop 3.6° with each 1000 ft of
elevation gain. Find the expected temperature after each 1000-ft gain.
Answer:
The temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.
Step-by-step explanation:
Given that W. Altus is climbing 3,000 feet to the top of a mountain, starting at a temperature of 60ºF, which decreases 3.6ºF every 1,000 feet of elevation, to determine the temperature every 1,000 feet of elevation, the following calculations must be performed:
0 feet = 60ºF
1,000 feet = 60ºF - 3.6ºF = 56.4ºF
2,000 feet = 56.4ºF - 3.6ºF = 52.8ºF
3,000 feet = 52.8ºF - 3.6ºF = 49.2ºF
Thus, the temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.

Answer:
X=2
Step-by-step explanation:
If the smaller triangle's base is 1.5ft and the bigger triangle's base is 6ft then in order to find x you have to find how much bigger the big triangle is compared to the small triangle in order to do that you have to divide 6 by 1.5 (6÷1.5) which is 4 now you know that the bigger triangle is 4 times as big as the smaller triangle now to find X divide the 8 by 4 (since the 8 is on the same side as the X only the 8 is on the bigger triangle) which is 2
Two right triangles will be congruent under a variety of scenarios besides HL. One of which is the following:
If the hypotenuse and an acute angle of one right triangle are equal,respectively, to the hypotenuse and an acute angle of another, then the right triangles are congruent. (Use the two triangles below, mark them up and then
decide on which congruence theorem will prove that the two are congruent (SAS, SSS, ASA, AAS or HL).
Explain why this must be true.
Answer:
Step-by-step explanation:
Both the triangles will be congruent by AAS property of congruence.
It has been given in the question,
Hypotenuse and an acute angle of both the triangles are equal.One angle of both the triangles measure 90°.Property of congruence A-A-S (Angle-Angle-Side) states,
"If two angles and a non-included side of one right triangle are equal to the corresponding angles and side of other triangle, then triangles will be congruent."
Therefore, by the property of AAS property of congruence, given right triangles will be congruent.

A farmer raised a watermelon that weighed 20 Lb. From his experience with raising watermelons, he estimated that 95% of the watermelon's weight in water. Question: In pound's how much water of the watermelon is water.
Answer:
19
Step-by-step explanation:
5%= 1
95%=19
The water is 95% of the total weight of watermelon. Multiply 95% by the total weight to get the weight of the water.
water = 95% × 20
water = 0.95 × 20
water = 19
The weight of the water is 19 lbs
