What is the slope of the line that passes through the points (9, -10) and (14,5)?
Write your answer in simplest form.
Answer:
3
Step-by-step explanation:
so you have to use the equation
y2 - y1 / x2 - x1
to find the slope
now all you have to do is substitute
-10 - 5 / 9 - 14
-15/ -5

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(9,\:-10\right),\:\left(x_2,\:y_2\right)=\left(14,\:5\right)[/tex]

Answer: Choice D
181 grams
======================================================
Explanation:
First we need to find the volume of the tennis ball
Since the diameter is d = 6 cm, it divides in half to a radius of r = 3 cm.
[tex]V = \text{volume of a sphere}\\\\V = \frac{4}{3}\pi*r^3\\\\V \approx \frac{4}{3}*3.14*3^3\\\\V \approx 113.04 \ \text{ cm}^3\\\\[/tex]
This leads to
[tex]\text{density} = \frac{\text{mass}}{\text{volume}}\\\\D = \frac{M}{V}\\\\M = D*V\\\\M \approx 1.6*113.04\\\\M \approx 180.864\\\\M \approx 181 \text{ grams}\\\\[/tex]
What is 89% of 260 sec?
pls help
Answer:
3.85666667 minutes of 260sec
Hey there!
89% of 260
= 89/100 of 260
= 89/100 * 260/1
= 23,140 / 100
= 23,140 ÷ 20 / 100 ÷ 20
= 1,157 / 5
= 231 2/5
≈ 231.4
Therefore, your answwr should be: 231.4

Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Answer:
Step-by-step explanation:
Image result for Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.
The price of the pants after tax is $35.31
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Price of the pants before tax= $33 and tax rate as 7%
Thus 7% of 33=2.31
Thus price after tax is equal to $33+$2.31=$35.31
Hence, The price of the pants after tax is $35.31

Which graph represents f(x)=−2cos(4πx)?
Answer:
the last one (bottom right)
Step-by-step explanation:
4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2
so, we only need to look, where the function reaches -2.
it should be at x = 0, x = 0.5 and x = 1.
Suppose the monthly charges for cell phone plans in the U. S. Are normally distributed with a mean of $62 and a standard deviation of $10. What is the proportion of cell phone plans charging less than $42 a month for service?
Using the normal distribution, it is found that 0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 62, \sigma = 10[/tex].
The proportion of cell phone plans charging less than $42 a month for service is the p-value of Z when X = 42, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{42 - 62}{10}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.

4. A cube has a volume of 64 m². What is the cube's surface area?
12 points!!! <333
Answer:
Surface area = 96 m^2
Step-by-step explanation:
Let's cube root the volume to find the length of one side of the cube.
[tex]64^\frac{1}{3} = 4[/tex]
Therefore each side is 4 m.
Surface area of one side = 4x4 = 16
A cube has 6 sides.
Total surface area of the cube = 16*6 = 96 m^2
