B (6,0)
C (-6,-5)
D (12,-4)
E (0,1/4)
Answers
Answer:
Step-by-step explanation:
recall that perpendicular lines have slopes that are opposite reciprocals. if u don't know what opposite reciprocals are, according to study.com they are, "The term opposite reciprocals refers to two numbers that have opposite signs and are flipped fractions of each other." for example, 1/2 and -2 are opposite reciprocals.
also recall that the formula to find the slope of a line is m=y2-y1/x2-x1
to solve this problem, we need to go through all of the options and find the slope of that line using the given point and point (0,4). After that, we need to check if that slope is equal to 1. One is the opposite reciprocal of -1, and -1 is the slope of the equation y= -x+4. if the slope is equal to 1, the line will be perpendicular to the line y= -x+4.
lets do the math now:
option a)
m=y2-y1/x2-x1
m=12-4/6-0
m=8/6
m=4/3
this line isnt perpendicular to y= -x +4 cuz the slope is 4/3, which isnt equal to 1
option b)
m=y2-y1/x2-x1
m=0-4/6-0
m=-4/6
m= -2/3
this line isnt perpendicular to y= -x +4 cuz the slope is -2/3, which isnt equal to 1
--------------
ok girl i dont wanna do all the rest of the calculations. just keep doing the same thing with all the other options until you find something that has a slope of 1.

the y intercept was the only tricky part
Answer:
f(x)=1x-8
Step-by-step explanation:
slope: 0-(-7)/ 8-1 = 7/7= 1
eg. (1,-7)
-7= 1 -y int.
y int. = 8
therefore:
f(x) = 1x-8

Find the values of p and q given that x⁴ + x³ - 7x² + px + q is divisible by (x - 1) and (x + 2)
Answers
Answer:
p = - 5, q = 10
Step-by-step explanation:
If f(x) is divisible by (x - h) then f(h) = 0
Here
f(x) = [tex]x^{4}[/tex] + x³ - 7x² + px + q
dividing by (x - 1) with h = 1 , then
[tex]1^{4}[/tex] + 1³ - 7(1)² + p + q = 0, that is
1 + 1 - 7 + p + q = 0
- 5 + p + q = 0 ( add 5 to both sides )
p + q = 5 → (1)
Dividing by (x + 2) with h = - 2 , then
[tex](-2)^{4}[/tex] + (- 2)³ - 7(- 2)² - 2p + q = 0 , that is
16 - 8 --- 28 - 2p + q = 0
- 20 - 2p + q = 0 ( add 20 to both sides )
- 2p + q = 20 → (2)
Subtract (1) from (2) term by term, thus eliminating q
- 3p = 15 ( divide both sides by - 3 )
p = - 5
Substitute p = - 5 into (1) and solve for q
- 5 + q = 5 ( add 5 to both sides )
q = 10

work.
Part B: How much will Kylie pay for the shoes after the discount? Show your
work.
Answers
Answer:
Part A: $13.76 saved. Part B: $55.04
Step-by-step explanation:
Part A: Set a proportion up d/68.8 = 20/100
100·d=100d 68.8·20=1376
100d/100 cancels out
1376/100=13.76 so $13.76 was saved
Part B: 68.80-13.76= 55.04 so $55.04 was what he paid.

The body temperature in Fahrenheit of a sheep is modeled by the equation T=0.6sin(π28(t−9))+101.6, where t is the number of hours. To the nearest tenth of a degree, what is the temperature of the sheep when t=3? Do not include the units in your answer. NOTE: The angle is in degrees.
Answers
Answer:
101.6
Step-by-step explanation:
The temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.
Given that,
The body temperature in Fahrenheit of a sheep is modeled by the equation,
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
where t is the number of hours.
Now, substitute t=3 into the equation;
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
Since, [tex]sin(\dfrac{\pi }{28} (- 6)) = - 0.5637[/tex]
Therefore, the temperature of the sheep when t=3 is:
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
[tex]T = 0.6 \times - 0.5637 + 101.6[/tex]
[tex]T = 101.24[/tex]
So, the temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.

x=6
Answer:
Since x = 6, the equation only has one solution.
Step-by-step explanation
You have to solve the equation first.
Let's solve your equation step-by-step.
4 ( x + 1 ) = 3x + 10
Step 1: Simplify both sides of the equation.
4 ( x + 1 ) = 3x + 10
( 4 ) ( x ) + ( 4 ) ( 1 ) = 3x + 10 (Distribute)
4x + 4 = 3x + 10
Step 2: Subtract 3x from both sides.
4x + 4 − 3x = 3x + 10 − 3x
x + 4 = 10
Step 3: Subtract 4 from both sides.
x + 4 − 4 = 10 − 4
x = 6
Answer:
x = 6
Did you know that an unopened 355 mL can of diet Dr. Pepper will float in a lake? That's a fact! However, it's also a fact that an unopened 355mL can of regular Dr. Pepper will sink in that same lake! Based on these two facts, which type of soda is the least dense? Explain your answer.
Answers
Answer: An unopened can of Diet Dr. Pepper is the least dense.
Step-by-step explanation:
For a solid object to float in a liquid, it must be less dense.
Let's associate the density of Diet Dr. Pepper with x, Dr. Pepper with y, and lake water with z.
Because of the above fact, x < z, and y > z. Thus, x < z < y, and x < y.
Hope it helps :) and let me know if you want me to elaborate.
