38 °F is the temperature after 5 hours of time.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that the temperature is 36 °F.
The temperature decreases for 4 hrs
Each hour, the temperature decreases by 2 °F.
1 hour= 2 °F.
For 4 hours it will be 4(2)=8 °F.
So the temperature after 4 hours is 36-8=28 °F.
the temperature rises 10 °F in one hour
28 °F+10°F=38 °F
Hence, the temperature after 5 hours is 38 °F.

Answer:
1st and 2nd options
Step-by-step explanation:
Using the method of completing the square to obtain standard form
(13)
Rearrange the given equation so x and y terms are together, that is
x² + 24x + y² + 30y + 353 = 0 ( subtract 353 from both sides )
x² + 24x + y² + 30y = - 353
To complete the square
add ( half the coefficients of the x/ y term)² to both sides
x² + 2(12)x + 144 + y² + 2(15)y + 225 = - 353 + 144 + 225
(x + 12)² + (y + 15)² = 16
(x + 12)² + (y + 15)² = 4² ← in standard form
with centre = (- 12, - 15 ) and radius = 4
---------------------------------------------------------------------
(14)
As in number 13
x² - 22x + y² + 16y = - 181
Complete the square
x² + 2(-11)x + 121 + y² + 2(8)y + 64 = - 181 + 121 + 64
(x - 11)² + (y + 8)² = 4
(x - 11)² + (y + 8)² = 2² ← in standard form
with centre = (11, - 8 ) and radius = 2

Someone look at the photo and answer I need help
Step-by-step explanation:
To find the composite function, it says
[tex](f \: o \: g)(x)[/tex]
means we put the function g(x) into f(x) so that means it looks like
[tex]( \sqrt{x}) {}^{2} - 4[/tex]
Which equal
[tex]x - 4[/tex]
So that expression above is the answer.
To find the range we must find the range of the inner function ,(g(x) and then see which parts it corresponds of f(x).
The range of a g(x) which is a radical function is all real numbers.
The range of a f(x) which is a quadratic function is all real numbers greater than or equal to -4.
This means for our function to work we can use any numbers as long as it greater than -4.
So we would represent that as x is all real numbers as long as x is greater than or equal to -4
In interval notation this would be
[-4,+ infintiy)

by what number should-15/56 be divided to get -5/6
pls pls pls pls I need your help
Answer:
The desired divisor is n = 21
Step-by-step explanation:
Let that number be n. Then:
-15/56 -5
---------- = ---------
n 6
Through cross-multiplication we get:
(-15/56)*6 = -5n, which reduces to:
(-15)(7) = -5n, or 3(7) = n
The desired divisor is n = 21

When Brad was born, his Grandma put, $1,500 in a new account for him. Since then, the balance of the account, has grown by 6.5% each year with no other deposits or withdrawals. Now Brad is 18 and can withdraw the money. If he decides to wait until his 21st birthday, how much more money will be in the account?
Answer:
$969.04
Step-by-step explanation:
now at age of 18 Brad has 1500 * 1,065^18
at age of 21 he will have 1500 * 1,065^21
if he waits the difference will be 1500 * 1,065^21 - 1500 * 1,065^18 = $969.04
An amount of $292.5 will be more if the money is taken after 21st birthday that that in 18th birthday.
What is Simple Interest?Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Given that,
Principal amount, P = $1500
Rate of interest, r = 6.5% = 0.065
The final amount in a simple interest is,
A = P (1 + rt), where t is the number of years.
After 18 years,
Amount = 1500 [1 + (0.065 × 18)]
= 1500 × 2.17
= $3255
After 21 years,
Amount = 1500 [1 + (0.065 × 21)]
= 1500 × 2.365
= $3547.5
Difference = $3547.5 - $3255 = $292.5
Hence the difference of the amount is $292.5.

The length of an arc AB from the given circle with radius 6in is 15.7in
Length of an arcThe formula for calculating the length of an arc is expressed as:
L = r theta
where
r is the radius = 6in
theta is the central angle = 150 degrees = 5/6π rad
Substitute
L = 6(5/6π)
L = 5π
L = 5(3.14)
L = 15.7in
Hence the length of an arc AB from the given circle with radius 6in is 15.7in

9x^2+ 3x – 2 = 0
Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3

A group of friends were working on a student film. They spent all their budget on equipment and costumes. They spent $737 on equipment, and 33% of the total budget on costumes. What was the total budget for their student film?
Answer:
Budget= $1,100
Step-by-step explanation:
Giving the following information:
They spent $737 on equipment and 33% of the total budget on costumes.
If they spent all their budget on equipment and costumes, then the percentage spent on equipment was 67% (100 - 33).
Then, to calculate the total budget, we need to use the following formula:
Budget= 737 / 0.67
Budget= $1,100

y=-16
Step-by-step explanation:
2(y-4)-5(y+8)=0 (distribute the 2 and the negative 5)
2y-8-5y-40=0 (combine like terms)
-3y-48=0 (add 48 to both sides)
-3y=48 (divide both sides by -3)
y=-16
