How do you do b and c?
Answer:
b) 18
c) 80.78
Step-by-step explanation:
While we can solve this equation with separation of variables, it isn't necessary. The coffee is originally at 95°, and the ambient temperature is 18°. The top right graph is the only one that shows this trend.
As t approaches infinity, y approaches the ambient temperature of 18°.
yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)
yₙ₊₁ = yₙ + 2 (-0.02 (yₙ − 18))
yₙ₊₁ = yₙ − 0.04 (yₙ − 18)
yₙ₊₁ = 0.96 yₙ + 0.72
When n=0:
y₁ = 0.96 y₀ + 0.72
y₁ = 0.96 (95) + 0.72
y₁ = 91.92
When n=1:
y₂ = 0.96 y₁ + 0.72
y₂ = 0.96 (91.92) + 0.72
y₂ = 88.96
When n=2:
y₃ = 0.96 y₂ + 0.72
y₃ = 0.96 (88.96) + 0.72
y₃ = 86.12
When n=3:
y₄ = 0.96 y₃ + 0.72
y₄ = 0.96 (86.12) + 0.72
y₄ = 83.40
When n=4:
y₅ = 0.96 y₄ + 0.72
y₅ = 0.96 (83.40) + 0.72
y₅ = 80.78

Step-by-step explanation:
one school purchased 18 gallons of blue paint to decorate several of its classrooms. if each classroom needs 1 4/5 gallons of paint, then how many classrooms will get painted.
Answer:
18 gallons of paint could paint 10 classrooms.
Step-by-step explanation:
Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:
4/5 = 0.8
1 + 0.8 = 1.8
18 / 1.8 = 10
Therefore, 18 gallons of paint could paint 10 classrooms.

Answer:
a.(-1,8), (2,9) b. (2,0) (3,5)
Step-by-step explanation:
a.
for (-4, 7) slope is [tex]\frac{1}{3}[/tex]
slope is m=rise /run =rise 1/run3 so to go to the next point
from (-4,7)
rise 1 so now you are at (-4,8) and run 3 and you are at (-1,8)
from (-1,8)
rise 1 to (-1, 9) and run 3 to (2,9)
b
(1,-5) slope is [tex]\frac{5}{1}[/tex]
from (1,-5) rise 5 to (1,0) and run 1 to (2,0)
from (2,0) rise 5 to (2,5) and run 1 to (3,5)

Mia went into a fair with $55.75 in her pocket. She bought a hot dog and drink for $2.975 each and then wanted to spend the rest of her money on rids tickets, which costs $0.95 each. Write an inequality to represent the total where r is the number of tickets purchased.
What is the maximum number of tickets mia can buy or purchesed_______?
Graphs how many rides tickets can mia buy without going over her budget.?
Answer: Maximum tickets she can buy is 52
Step-by-step explanation:
After she bought the fries and drinks she was left with $49.81. If she spent the rest of her money on rides/tickets for the rides then she bought 52 tickets to be exact. 0.95x52=49.40

Monica and her parents spent $170 on new swimsuits. Monica’s swimsuit cost $35. Her mom’s swimsuit cost twice as much as Monica’s. How much did her dad’s swimsuit cost?
━━━━━━━☆☆━━━━━━━
▹ Answer
Her dad's swimsuit costs $65.
▹ Step-by-Step Explanation
Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.
$170 - $35 = $135
Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:
$35* 2 = $70
We will now add Monica's cost and her moms' cost:
$35 + $70 = $105
To find Monica's dads' cost, we will subtract 105 from 170:
$170 - $105 = $65
Her dad's swimsuit costs $65.
Hope this helps!

Answer:
1. sin(x) = a/c; cos(x) = b/c; tan(x) = a/b
2, 3 see below
Step-by-step explanation:
1. The mnemonic SOH CAH TOA reminds you of the relationships between trig functions and sides of a right triangle:
Sin = Opposite/Hypotenuse ⇒ sin(x) = a/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = b/c
Tan = Opposite/Adjacent ⇒ tan(x) = a/b
__
2. The attachment shows the two special right triangles. The 30-60-90 right triangle has sides in the ratio 1 : √3 : 2. The 45-45-90 isosceles right triangle has sides in the ratio 1 : 1 : √2.
These ratios can be used to write proportions that help you find the length of a missing side.
Example:
Suppose the triangle in problem 1 has x = 30°, and a = 10. Then we could find the length of missing side 'c' using a proportion involving the short side and the long side (hypotenuse).
2/1 = c/10 ⇒ c = 20
__
3. In a right triangle, the acute angles are complementary. The side adjacent to one acute angle is the side opposite the other. So the sine of one of the angles is the cosine of the other, and vice versa. This means the sine of an angle is the cosine of its complement, and vice versa.
__
Comment on question 3
The wording of this question is a little strange. Sine and cosine are not complementary. Rather, the angles for which those functions have the same value are complementary.

Avram borrows $14,500 at 5.4% simple interest to open a small business. His bank allows him 9 years to pay back the loan. How much simple interest will Avram have to pay on the loan?
Answer:
Avram will have to pay $7,047 simple interest
Step-by-step explanation:
Simple Interest
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=A.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Avram has a principal of P=$14,500 at a simple rate of r=5.4%=0.054 for t=9 years, thus:
I=14,500*0.054*9=7,047
I=$7,047
Avram will have to pay $7,047 simple interest
Answer:
$7,047 simple interest
