Answer:
A and B: slope = 0
S and T: slope = undefined
Step-by-step explanation:
To find the slope of the line that passes between a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of two points into that formula and simplify.
1) Let's try this with the first problem. Substitute the x and y values of (4,5) and (-3,5) into the formula, then solve:
[tex]m = \frac{(5)-(5)}{(-3)-(4)}\\m = \frac{5-5}{-3-4} \\m = \frac{0}{-7} \\m = 0[/tex]
So, the slope of the line between A and B is 0.
2) Do the same with the second problem, substituting the x and y values of (3,-6) and (3,-9):
[tex]m = \frac{(-9)-(-6)}{(3)-(3)} \\m = \frac{-9+6}{3-3} \\m = \frac{-3}{0} \\[/tex]
However, we can't divide by zero. So, the slope between points S and T must be undefined.

A sphere has a radius of 12 inches. What is its volume
Answer:
26899 in³
Step-by-step explanation:
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 12 in, then the volume is V = (4π/3)(12 in)³, or approximately 26899 in³
Please help due soon!!
Answer: [(3/4)π] in² or (0.75π) in²
Step-by-step explanation:
Here, we are asked to find the area of a sector. So we are going to use the formula: A=πr²(θ/360)
--------------------------------------------------------------
Given
r=3 in
θ=30°
Solve
A=πr²(θ/360)
A=π(3)²(30/360)
A=9π(1/12)
A=[(3/4)π] in²
A=(0.75π) in²
Hope this helps!! :)

the Anser un the Fire one is B and the answer on the 2nd one is A
please look at picture. i will give brainliest to the correct answer!!!
Answer:
N = 30
Step-by-step explanation:
30 divided by 10 is three. Three plus three equals 6.
If the radius of a circle is 3, calculate the diameter.
also can anyone please explain how to do this? i would really appreciate it.
Answer:
The diameter would be 6
Step-by-step explanation:
the radius is half of a diameter, so you would have to double the radius to get the diameter
d=2r
=2(3)
=6
The diameter reaches across the circle, while the radius reaches only half way, so you would have to double the radius to get the diameter (2r)
sorry if this doesnt make sense
take care, stay safe, be careful, and live

OC. 5 quarters, 2 dimes, 3 nickels
OD. 6 quarters, 2 dimes, 2 nickels
Answer:
its C :)
Step-by-step explanation:
so 5 quarters is 1 dollar and 25 cents then add 2 dimes its 1 dollar and 45 cents then u add 15 because of 3 nickles and so it makes it 1 dollar 60 cents
Find the approximate length of the line AB PLZZZZZZZZZZZZZZZZZZ HELPPPPPP
Answer:
Approximate length of line AB is 8.6
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (8, 2)
Point 2 (xB, yB) = (3, 9)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^2 + (yB − yA)^2
Solution :
Distance between two points = √(3 − 8) ^2 + (9 − 2) ^2
= √(−5) ^2 + 7^2
= √25 + 49
= √74
= 8.6023
Distance between points (8, 2) and (3, 9) is 8.6023
hope this helps and is right :)
Answer:
First choice
12.0
Step-by-step explanation:
Make a right triangle, drawing straight lines, down from point A and left from point B. Use the pythagorean theorum to solve.
I will use "x," "y," and "z" as sides of the triangle as to not confuse between points a and b.
Line AB is line z
x^2 + y^2 = z^2
8^2 + 9^2 = z^2
64 + 81 = z^2
145 = z^2
(find square roots of both)
12.0416 = z
i just want some help please :( I’m tired of all these links .

Sandy invest $35,000 into a business. If she on 16% of the business, what is the total work for business?
A national study report released by the Center for Studying Health System Change (HSC) in 2010, indicated that 20.9% of Americans were identified as having medical bill financial issues. Many people in families with problems paying medical bills in 2010 experienced severe financial consequences from their medical debt, with about two-thirds reporting problems paying for other necessities and a quarter considering bankruptcy, the study found. What if a news organization randomly sampled 400 Americans from 10 cities and found that 90 reported having such difficulty. A test was done to investigate whether the problem is more severe among these cities. The result of this test is ________.
Answer:
The result of this test is 0.2156
Step-by-step explanation:
Given the data in the question;
The proportion of Americans having medical bill financial issues is ;
p = 20.9% = 0.209
CLAIM;
The problem is more severe among the cities
so
H₀ : p = 0.209
H₁ : p > 0.209 { this is our claim }
population n = 400
number of people that reported difficulty x = 90
so
sample proportion p" = x / n = 90 / 40 = 0.225
Test Statistics;
z = [ (p"-p) / √( (p(1-p))/n ) ]
we substitute
z = [ (0.225 - 0.209) / √( (0.209(1-0.209)) / 400 ) ]
z = [ 0.016 / √0.0004132976 ]
z = [ 0.016 / 0.0203297 ]
z = 0.787
P-VALUE
p-value = P( Z ≥ z )
p-value = P( Z ≥ 0.787 )
p-value = P( Z ≤ -0.787 )
from normal distribution table;
p-value = P( Z ≤ -0.787 ) = 0.2156
p-value = 0.2156
Therefore, The result of this test is 0.2156

A 40-meter-long blade of a wind turbine makes one complete revolution in 10 seconds. To the nearest tenth, the linear velocity of the blade is meters per second.
Answer:
25.13 m/s
Step-by-step explanation:
Linear velocity = Distance / time
The distance = Circumference of turbine = 2πr
Radius, r = 40 m
Circumference= 2 * π * 40 = 251.327
The linear velocity is thus :
Circumference / time
= 251.327m / 10s
= 25.13 m/s

How can you determine the part of an hour that is 15 minutes?
Answer:
You'll need to convert the minutes part to hours. 15 minutes times 1 hour per 60 minutes will make the conversion to hours and minutes will cancel out. 0.25 hours times 60 minutes per 1 hour = 0.25 hr × (60 min/ 1hr) = (0.25 × 60) min = 15 minutes.

A circular pool has a
circumference of 65.94 ft.
What is the pools diameter?
Answer: 20.989353895 or round it up to 21
Step-by-step explanation:
If we want to find a diameter of a circle and given a circumference, we divide the circumference by pi
so 65.94 divide by pi = 20.989353895

Answer:
None of he choices are correct. Now before you say I'm wrong, look at any one of the unknown angles. You can plainly see that they each are greater than 90 °.
x = 120°
Step-by-step explanation:
5 sides
(180 x 5) - 360 = 540° total of interior angles
540 - 90 - 90 = 360° total for the 3 unknown angles
x = 360/3 = 120°
