Step-by-step explanation:
Answer:
x=−2
Step-by-step explanation:
Slope = 0.500/2.000 = 0.250
x-intercept = 8/1 = 8.00000
r-intercept = 8/-4 = 2/-1 = -2.00000
Jia has $44,000 in a savings account. The savings collect interest at a 6% annual rate that compounds every year. How much money will be in Jia's account after 2 years?
Answer:
the answer is ieff = 2% - 3.24%
ieff = - 1.24% = -0.0124
Therefore the money left after 1 year would be:
F = 44,000 * (1 – 0.0124)
F = 43,454.4
So the amount of money lost is:
lost = 44,000 - 43,454.4
lost = $545.6

-8>4+2v
How do you do this
Answer:
Step-by-step explanation:
-8 > 4 +2v ; subtract 4 from both sides
-8-4 > 4-4 +2v; calculate
-12 > 2v; divide both sides by 2
-6 > v
TO Know:
apply the same operation to both sides of inequality
if the operation is dividing or multiplying by a negative number change the direction of the inequality

If x+40=? type your answer below.
Part A
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Part B
What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Part C
The pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.
Part D
Search the Internet to find the length of each side of the base of Khufu’s pyramid. Does this length match your calculation?
Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?
Part F
Search the Internet to find the length of each side of the base of Khafre’s pyramid. Does this match your calculation?
Part G
About how much longer are the side lengths of the base of Khufu’s pyramid than Khafre’s?
Answer:
Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

Answer:
All you have to do is multiply 5 and 3 by specific gaps in between new numbers then subtract 30. Keep doing that until you get evenly matched numbers.
Step-by-step explanation:
The answer is 15, it would take 15 seconds for Alan to reach Sasha.

Step-by-step explanation:
4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Write yes or no and explain your reasoning by showing work.
Answer:
YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Step-by-step explanation:
Given
Given that the function f(x) and g(x) are inverse functions.
[tex]f\left(x\right)\:=\:\frac{1}{3}x\:+\:5[/tex]
[tex]g(x) = 3x - 15[/tex]
To determine
Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Determining the inverse function of f(x)
A function g is the inverse function of f if for y = f(x), x = g(y)
[tex]y=\frac{1}{3}x+5[/tex]
Replace x with y
[tex]x=\frac{1}{3}y+5[/tex]
Solve for y
[tex]y=3x-15[/tex]
Therefore,
YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
What is the simplified base for the function f(x) = 2(7272x)?

O 3
O 9
O 18
Answer:
C.9
Step-by-step explanation:
The simplified base for the function given is 9.
What is a function?A function in math is a rule or expression that defines a relationship between one variable (the input or independent variable) and another variable (the output or dependent variable). A function assigns to each input exactly one output.
Given that, a function f(x) = 2(∛27)²ˣ, we need to find its simplest base,
So,
f(x) = 2(∛27)²ˣ
= 2(3)²ˣ [∵ 3³ = 27, ∴ ∛27 = 3]
= 2(3²)ˣ
= 2(9)ˣ
Hence, the simplified base for the function given is 9.

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

Answer:
26% for romance and look in the explanation for other answer
Step-by-step explanation:
So to find a relative frequency you add up everything. so 30 for the results all together then you take whatever it focuses on and turn it into a fraction.
For question F it would be 8/30 or .26%
Then for the next answer the most popular movie genre would be romance at 26%.
Question H is more likely to pick for a movie which would least likely be comedy because its the lowest in the class at 13%
