Answer:
x = 21
Step-by-step explanation:
The parallel lines divide the segments proportionally.
x/27 = 28/36
x = 27(28/36) . . . . multiply by 27 (in your head: (3·9)(4·7)/(4·9) = 3·7)
x = 21
Help lol I’m bad at mafs and I need halp
Answers
Answer:
(A) 5^3 * 5^-4
= 5^(3-4)
= 5^(-1)
= 5^-1
= 1/5^1
= 0.2
Yes, expression has value between 0 and 1
(B) 3^5 / 3^-6
= 3^5 * 3^6
= 3^(5+6)
= 3^(11)
= 177147
No, expression does not have value between 0 and 1
(C) (1/4)^3 * (1/4)^2
= (1/4)^(3+2)
= (1/4)^(5)
= (1^5/4^5)
= 1 / 4^5
= 1 / 1024
= .000977
Yes, expression has value between 0 and 1
(D) (-7)^5 / (-7)^7
= (-7)^5 * (-7)^-7
= (-7)^(5-7)
= (-7)^(-2)
= 1 / (-7)^2
= 1 / 49
= 0.02041
Yes, expression has value between 0 and 1
Step-by-step explanation:
For these problems we need to know a few things:
(1) Powers of like bases, you add the exponent
This means the following:
x^y * x^z = x^(y+z)
Or
x^y / x^z = x^(y-z)
(2) Negative powers can be swapped on the fraction to be positive
This means the following:
x^-y = 1 / x^y
Or
1 / x^-y = x^y
Using these two things, we can easily simplify all the expressions given.

2,037 divided by 39 with the remaining
Answers
Answer:
53 remainder 23
= 53 23/38
Step-by-step explanation:
Answer:
52 with 9 remaining
Step-by-step explanation:
When dividing this, we find that our whole number we are going to multiply with is 52, and if it was 53 it would be over 2,037. So, we multiply 39 by 52 and get 2,028, which is an extra of 9 remaining.
2(6 + 3n) - 4
i need the answer...
.....
Answers
Answer:
See below.
Step-by-step explanation:
2(6 + 3n) - 4 (Given)
12 + 6n - 4 (Distribute)
6n + 8 (Add like terms)
3n + 4 (Divide by a factor of 2)
In case you wanted to solve for n:
2(6 + 3n) - 4 = 0 (Given)
12 + 6n - 4 = 0 (Distribute)
6n + 8 = 0 (Add like terms)
6n = -8 (Substract on both sides)
n = -4/3 (Divide 6 on both sides)

A2. Find y' and y" for y^2 = x^2
+ sinxy
Answers
Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)

Portray the cumulative distribution in the form of a cumulative frequency polygon.d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
Answers
Answer:
a. How many employees accumulated less than 3,000 miles?
The number of employees accumulated less than 3,000 miles= 5
So the number of employees accumulated less than 3,000 miles is 5.
d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.
Step-by-step explanation:
The given frequency distribution representing the number of frequent flier miles accumulated by the employees in a company.
Frequent Flier Miles (000) Frequency
0 up to 3 5
3 up to 6 12
6 up to 9 23
9 up to 12 8
12 up to 15 2
Total 50
a. How many employees accumulated less than 3,000 miles?
The number of employees accumulated less than 3,000 miles= 5
So the number of employees accumulated less than 3,000 miles is 5.
b. Convert the frequency distribution to a cumulative frequency distribution.
We make the cumulative frequency distribution from the frequency distribution by adding up a frequency and all other frequencies below it.
Frequent Flier Miles Frequency Cumulative frequency
0 up to 3 5 5
3 up to 6 12 17
6 up to 9 23 40
9 up to 12 8 48
12 up to 15 2 50
Total 50
d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.

what is equavilent to (10x+7r-r^(2))+(-6r^(2)-18+5r)
Answers
Answer:
−7r^(2)+12r+10x−18
Step-by-step explanation:
Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r
For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r
Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)
Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18
