g(n)=n^2-4
h(n)=4n+5
find g°h
Answer: g(4n+5) = 16n^2 + 40n + 30
Step-by-step explanation:
g(n)=n^2-4
h(n)=4n+5
find g°h
g°h is g(4n+5) = (4n+5)^2 + 5
g(4n+5) = (16n^2 + 40n + 25) + 5
g(4n+5) = 16n^2 + 40n + 30

Answer:
[tex] \frac{88}{4} \\ 22 \\ here \: u \: go[/tex]
Answer:
22 cm
Step-by-step explanation:
The angle subtended at the centre by the arc is 90°
This represents [tex]\frac{90}{360}[/tex] = [tex]\frac{1}{4}[/tex] of the circle
The arc length will be quarter of the circumference, that is
arc = [tex]\frac{1}{4}[/tex] × 88 = 22 cm

Given numbers 2 ,5,11, 4.5, 1/10, V3 then
a. Write two prime numbers from the above.
b- An integer root 121
c- A number 25 % of 18
d- An irrational number
Answer:
a. pick two between 2,5 or 11, they are all primes.
b. it's 11 since
[tex]11 {}^{2} = 121[/tex]
c. that's
[tex]18 \times \frac{25}{100} = 4.5[/tex]

How many solutions does this equation have. 3x + 99 = 3 (x + 33)
Answer:
Infinitely many solutions
Step-by-step explanation:
3x + 99 = 3 (x+33)
distribute 3 to x and 33
3 * x = 3x
3 * 33 = 99
3x + 99 = 3x + 99
If the expressions on both sides of the equal sign are the same, then solving for them would result in 0 = 0 meaning that the equation has infinitely many solutions

Find all sets of 2 consecutive positive integers with a sum that is at least 8 and less than or equal to 24.
Answer:
An odd integer is denoted by 2n+1 where n is an integer.
First odd integer = 2n+1
Next odd integer = 2n+3
8 ≦ (2n+1)+(2n+3) < 24
8 ≦ 2n+1+2n+3 < 24
8 ≦ 4n+4 < 24
Divide through by 4
2 ≦ n+1 < 6
Subtract 1 for all three sides:
1 ≦ n < 5
n ∈ {1,2,3,4}
Answer: {2n+1, 2n+3} {1,3}, {3,5}, {5,7

Answer:
Multiply both sides by 6: 4x - 42 = 5
Step-by-step explanation:
(2/3)x - 7 = (5/6)
Multiply both sides by 6:
6*(2/3)x - 6*7 = 6*(5/6)
(12/3)x - 42 = 5
4x - 42 = 5

The area of the regular pentagon is 6. 9 cm2. A regular pentagon has an apothem with length 1. 38 centimeters and an area of 6. 9 centimeters squared. What is the perimeter? 2 cm 5 cm 10 cm 20 cm.
The perimeter of the regular pentagon is 10 centimeters.
Given that the area of the regular pentagon is 6.9 cm2, and a regular pentagon has an apothem with length 1.38 centimeters and an area of 6.9 centimeters squared, to determine what is the perimeter the following calculation must be performed:
(Perimeter x apothem) / 2 = Area 1.38X / 2 = 6.9 1.38X = 13.80 X = 13.80 / 1.38 X = 10
Therefore, the perimeter of the regular pentagon is 10 centimeters.

3 3/22
Step-by-step explanation:
a) he subtracted 5 from a mixed fraction without converting it first
and for 1 1/2 - sign should be there
b) first convert mixed fraction and add the terms in the parentheses
c) 9 7/11 - (5 + 1 1/2)
= (9*11 + 7) / 11 - ( 5 + (1*2 + 1)/2 )
= 106/11 - (5 + 3/2)
= 106/11 - (5*2 + 3)/2
= 106/11 - 13/2
= lcm of 2 and 11 is 22
= (106*2 - 13*11) / 22
= (212 - 143) / 22
= 69/22
= 66 + 3 / 22
= 3 3/22
The farmer bought 2.5 sacks of fertilizer for $2.20 per sack and 4.5 sacks of essential soil for $1.80 for each sack from the supplier. If he gave a $15 bill to the supplier, how much would his change be?
Answer:
$0.50 or 50 cents
Step-by-step explanation:
If he bought 2 and a half sacks of fertilizer for $2.20 that means u multiply 2.20 2 and a half times so first lets divide 2.20 by 2 to find the solution of the "0.5" which is 1.10
2.20 times 2 equals 4.40 then we add the 1.10 so 4.40 plus 1.10 is $5.50.
For the 4.5 sacks of 1.80 we will do the same technique half o 1.80 is 90 cents so 0.90 and 4.5 times 1.80 is $8.10 we then add the 90 cents making it $9.
We then add the 2 totals of $9 and $5.50 which equals $14.50, the change would be 50 cents which in decimal form would be $0.50

The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):
Part A: Describe two types of transformations that can be used to transform f(x) to g(x).
Part B: Solve for k in each type of transformation.
Part C: Write an equation for each type of transformation that can be used to transform f(x) to g(x).
Answer:
Step-by-step explanation:
The graph of f(x) becomes the graph of g(x) if the former is translated UP 18 units. k = 18.
The graph of f(x) becomes the graph of g(x) if the graph of f(x) is translated 6 units to the left. k = 6

What is an equation of the line perpendicular to y=1/5x+2
That contains (15, -4)?
PLS HELP
Answer:
y+4=-5(x-15)
Step-by-step explanation:
Use point-slope form:
y-y1=m(x-x1)
m is the slope
x1 is the x coordinate of the point that the line contains
y1 is the y coordinate of the same point
We are already given the coordinates of the point (15, -4), so we just need m, the slope.
We are given that equation of the line is perpendicular to line y=1/5x+2. Perpendicular lines have slopes that are negative reciprocals of one another. The slope of y=1/5x+2 is 1/5, so all we need to do it get the negative reciprocal of 1/5.
The negative reciprocal of 1/5 would be -5. (switch the numerator and denominator and slap on a negative)
Now we know
m is -5
x1 is 15
y1 is -4,
so plug those into point-slope form: y-y1=m(x-x1)
y-(-4)=-5(x-15)
y+4=-5(x-15) is the answer
