let
(hypotenuse ) c = 10 in
(perpendicular) a = 8 in
(base) b =?
By using Pythagoras theorem
c^2= a^2+b^2
(10)^2 = (8)^2 +(b)^2
100 = 64 +(b)^2
100- 64 = (b)^2
36 = (b)^2
√36 = b
6 = b
hence b= 6 in

Question #2, show how you know
Answers
Answer: Choice B is correct.
==================================================
Explanation:
We are told that the derivative function f ' (x) is positive for all real numbers x. This means that f(x) is increasing for all real numbers. An increasing function goes uphill as you move from left to right. This rules out choices C and D.
We're also told that the integral of f(t), from t = 4 to t = 7, is equal to 0. Because f(x) is increasing, this must mean that some portion of f(x) is below the x axis and some portion is above the x axis when focused on the interval of [tex]4 \le x \le 7[/tex]. This allows us to rule out choice E since there are no portions that are below the x axis here.
At this point, the answer is between A and B. We can rule out choice A for similar reasoning we did with choice E. This time, there is no portion that is above the x axis. We need a negative area (below the x axis) to counterbalance with a positive area (above the x axis) so that the two areas cancel out and add to 0. That doesn't happen with choice A.
The only thing left is choice B so that must be the answer. We have a portion below the x axis and a portion above it, so it's possible that these two areas cancel out to add to 0. Since we don't know the actual f(x) function, it's impossible to tell whether that happens or not.

Step-by-step explanation:
Complementary angles are angles that add up to give us 90°.
Since <A and <B are complementary angles, it implies that:
m<A + m<B = 90°
If m<A = 35°, therefore:
35° + m<B = 90°
Subtract 35° from each side
m<B = 90° - 35°

Advise your mother on how much she should withdraw from her bank at the end of each year for the duration of the desired life span? [10 marks]
Answers
Answer:
You'll need to look at the attached formula.
Annual Payout = 500,000 * .12 * (1.12)^15 / [(1.12)^15 -1]
Annual Payout = 500,000 * .12 * 5.4735657593 / [ 5.4735657593 -1]
Annual Payout = 500,000 * .12 * 5.4735657593 / [4.4735657593]
Annual Payout = 60,000 * 5.4735657593 / [4.4735657593]
Annual Payout = 73,412.12

A model predicts that the population of a certain town was 10,000 in 2001. The model also
predicts that each year for the next 5 years, the population p increased by 8% of the previous
year's population. Which equation best represents this model, where X is the number of years after
2001, for X < 5?
Answers
Answer:
The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]
Step-by-step explanation:
Exponential equation for population growth:
The exponential equation for population growth, after x years, is given by:
[tex]P(x) = P(0)(1+r)^x[/tex]
In which P(0) is the initial population and r is the growth rate.
A model predicts that the population of a certain town was 10,000 in 2001.
This means that [tex]P(0) = 10000[/tex]
8% yearly increase.
This means that [tex]r = 0.08[/tex]. So
[tex]P(x) = P(0)(1+r)^x[/tex]
[tex]P(x) = 10000(1+0.08)^x[/tex]
[tex]P(x) = 10000(1.08)^x[/tex]
The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]

Answer:
5
Step-by-step explanation:
If you subtract the same thing from both sides, and you are left with 0 = 0, there are infinitely many solutions.
5x + 5 = 5x + ____
Subtract 5x from both sides.
5 = ____
What do you need on the right side, so that when you subtract the same number from both sides you end up with 0 = 0? Answer: 5.
5 = 5
Subtract 5 from both sides.
0 = 0
Let's go back to the original problem, and use a 5 in the blank.
5x + 5 = 5x + 5
Subtract 5x from both sides, and subtract 5 from both sides.
0 = 0
Since 0 = 0 is a true statement, the equation is true for every value of x.

Answers
Answer:
P(25 < x < 37) = 0.77
Step-by-step explanation:
Given - If a Variable has a normal distribution with mean 30 and standard deviation 5
To find - find the probability that the variable will be between 25 and 37.
Proof -
Given that,
Mean, μ = 30
S.D, σ = 5
Now,
[tex]z = \frac{x-\mu}{\sigma}[/tex] ~ N(0,1)
Now,
P(25 < x < 37)
= [tex]P(\frac{25 - 30}{5} < z < \frac{37 - 30}{5} )[/tex]
= P(1 < z < 1.4)
= P(z < 1.4) - P(z < -1)
= 0.9192 - 0.1587
= 0.7605
≈ 0.77
∴ we get
P(25 < x < 37) = 0.77

2x(1) 2x - 6y - 2z = -18 (2) -2x + y + 2z = 3

In a study of housing demand, a county assessor is interested in developing a regression model to estimate the selling price of residential properties within her jurisdiction. She randomly selects several houses and records the selling price in addition to the following values: the size of the house (in square feet), the total number of rooms in the house, the age of the house, and an indication of whether the house has an attached garage. These data are stored in the file HousingDemand.
A. Estimate and interpret a multiple regression equation that includes the four potential explanatory variables. How do you interpret the coefficient of the Attached Garage variable?
B. Evaluate the estimated regression equation’s goodness of fit.
C. Use the estimated equation to predict the sales price of a 3000-square-foot, 20-year-old home that has seven rooms but no attached garage. How accurate is your prediction?

Answers
Answer:
Step-by-step explanation:
The total cost for the laptop for 3 years is $1174.20.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Cost of the laptop when purchased = $780
Daily cost = $0.36
Number of days in 3 years = 3 × 365 = 1095 days
Cost for the laptop for 3 years = 1095 × $0.36
= $394.20
Total 3 year cost = $394.20 + $780
= $1174.20
Hence the total cost for the laptop is $1174.20.
