Given f(x)=3x^2-2x+k, and the remainder when f(x) is divided by x-3 is 35, then what is the value of k?
compare the divisor x-3 with x-a which will give a=3 and then use remainder theorem.

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12Side = 23 unitsStep-by-step explanation:
STU is an equilateral triangle. And:
ST = 2x - 1SU = 5x - 37TU = x + 11All sides are equal. Then take one pair and solve for x:
2x - 1 = 5x - 373x = 36x = 12Substitute x to find the side length:
2x - 1 = 5x - 37 = x + 11 = 2316. A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental?
A. 75.00 + 160.00x = 760 00
B. 75.00x - 160.00 = 760.00
C. 75.00 - 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

You survey the students in your class to find out what kinds of movies they
like to watch. The students were given the following choices: Comedy (C),
Horror (H), Drama (D), Action (A), Romance (R).
The following were the results of your survey:
C, C, R, R, D, R, H, H, C, A, A, R, A, A, A, R, R, H, H, H, C, H, A, R, D, D, D, D, H, R
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%
I hope this helped I did my best to help.
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]

Eight bowls cost $160, but Adrien wants only 5 of them so how much does he have to pay?
Answer:
$100
Step-by-step explanation:
you have eight bowls so you divide 160 by 8 and you get 20 so each bowl is 20 so 5x20=100
Answer:
100
Step-by-step explanation:
First, calulate the cost of each bowl, so, 160/8=20
Next, calculate how much total it costs, so 20x5, which the answer is $100
What is the slope intercept ?
Please help me !!
Answer:
y=mx+b
Step-by-step explanation:
Answer:
slope=3, y-intercept=1
Step-by-step explanation:
slope is rise/run, so if you rise 3 and run 1 on the line, you get 4 for the slope, the y intercept is where the line crosses the y-axis, in this situation, it crosses it at (0,1).

How would I find the difference of 7/8 - 1/3 ?
Answer:
[tex]\frac{13}{24}[/tex]
Step-by-step explanation:
We have two fractions and are being asked to subtract them.
7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.
So what is the LCM (Least Common Multiple) of 8 and 3?
24.
Therefore :
[tex]\frac{7 * 3}{8 * 3} - \frac{1*8}{3*8}[/tex]
[tex]\frac{21}{24} - \frac{8}{24}[/tex]
[tex]\frac{13}{24}[/tex]
Answer:
13/24
Step-by-step explanation:
1. Common denominator:
common denominator = 24
multiply bottom and top so from 8 to 24 is 8x3, so multiply by three and what you do to the bottom you do to the top so,
7/8: 8 x 3 = 24 and 7 x 3 = 21 so the new fraction is 21/24.
Do the same to the other fraction: 1/3 multiply top and bottom by 8 because 3 x 8 = 24.
1/3 = 8/24
Now just subtract:
21/24 - 8/24 = 13/24 (There is your answer)
-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

Answer:
m=s+0.50
3m+2s=23.95
Step-by-step explanation:
Answer:
m-s+0.50
3m+2s=23.95
Step-by-step explanation:
the first one is defining m in terms of S
the second is solving
I know they didn't ask but here is the solution:
so in this case you would replace 3m with 3(s+0.50)
Find the 14th term of the geometric sequence 2, 6, 18,
The geometric sequence is starting with 2 and multiplying by 3 every time. We can get the rule of this sequence by...
If 2 is a_0, 6 is a_1, 18 is a_2, etc.
a_n=2*3^n
For the 14th term, which is a_13, the value is 2*3^13.
Using a calculator because I'm too lazy to calculate 3^13 sorry, we can get.
3188646
The required 14th term will be 3188646 in the given geometric sequence.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
The geometric sequence is given in the question, as follows:
2, 6, 18,...
We have to determine the 14th term of the given geometric sequence.
As per the given geometric sequence,
The first term a = 2.
The common ratio r = 6/2 = 3
14th term = arⁿ⁻¹
Substitute the value of a = 10, r = -2, and n = 12 in the formula,
14th term = 2(3)¹⁴⁻¹
14th term = 2(3)¹³
14th term = 2(1594323)
14th term = 3188646
Thus, the required 14th term will be 3188646.

Sam has already worked for 27.7 hours this week. He washes cars, and can wash a car in 2.5 hours. He wants to work over 60.2 hours this week.
The question is incomplete ; we could calculate the least number of cars he can still wash for the week expressed in inequality form.
Answer:
x > 13 ; 13
Step-by-step explanation:
Given that :
Anticipated work hour for entire week = 60.2 hours
Hours worked = 27.7 hours
Rate of car wash = 2.5 per hour
Hours left to work for the week :
60.2 - 27.7 = 32.5
Hours left / unit rate of car wash
32.5 / 2.5
= 13
Hours worked +( hours left * unit rate) > anticipated hours
27.7 + 2.5x < 60.2
2.5x > 60.2 - 27.7
2.5x > 32.5
x > 32.5 / 2.5
x > 13
Hence ; Sam could still wash over 13 cars this week

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.

Evaluate: log6 1,296
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] then
let [tex]log_{6}[/tex] 1296 = n
1296 = [tex]6^{n}[/tex] = [tex]6^{4}[/tex] , thus
n = 4
