Maya would like to invest her money in a savings account. The function A(t)=500(1.015)t represents the amount of money Maya will have in her savings account after t years. How long will it take Maya to have $800 in her account? Round your answer to the nearest tenth of a year.
Maya will have $800 in her saving account after 31.6 years.
Function representing the amount of money in Maya's saving account,
[tex]A(t)=500(1.015)^t[/tex]
Here, [tex]A(t)[/tex] = the final amount
[tex]500=[/tex] Initial amount
[tex]t=[/tex] Duration of investment
If the final amount in her saving account is $800,
Substitute the final amount as $800.
[tex]800=500(1.015)^t[/tex]
[tex](1.015)^t=\frac{800}{500}[/tex]
[tex](1.015)^t=1.6[/tex]
[tex]\text{log}(1.015)^t=\text{log}(1.6)[/tex]
[tex]t[\text{log}(1.015)]=\text{log}(1.6)[/tex]
[tex]t=\frac{\text{log}(1.6)}{\text{log}(1.015)}[/tex]
[tex]t=31.57[/tex]
[tex]t\approx31.6[/tex] years
Therefore, Maya will have $800 in her saving account after 31.6 years.

Answer:
1.6 ounces of cheese
Step-by-step explanation:
To make 6 slices of pizza, 9.6 ounces of cheese is used.
Therefore,
6 slices = 9.6 ounces of cheese
To find the ounces of cheese for 1 slice,
1 slice = 9.6 ÷ 6
= 1.6 ounces of cheese
What single decimal multiplier would you use to decrease by 1% followed by a 1% increase
Answer:
0.9999
Step-by-step explanation:
Original: 1
decrease by 1%: 1 * (1 - 0.01) = 0.99
followed by a 1% increase: 0.99 * ( 1 + 0.01) = 0.99 * 1.01 = 0.9999
Ginger buys lunch at school every day. She always gets
pizza when it is available. The cafeteria has pizza about
80% of the time.
Ginger runs a simulation to model this using a random
number generator. She assigns these digits to the possible
outcomes for each day of the week:
Let 0 and 1 = no pizza available
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available
Answer:
The estimated probability that Ginger will eat a a pizza everyday of the week is;
D. 8/10 = 80%
Step-by-step explanation:
The given parameters are;
The frequency with which Ginger buys launch = Everyday
The percentage of the time the cafeteria has pizza out = 80%
The outcome of 0 and 1 = No pizza available
The outcome of 2, 3, 4, 5, 6, 7, 8, and 9 = Pizza available
Therefore, we have the;
Group number [tex]{}[/tex] Percentage of time pizza available
1 [tex]{}[/tex] 80%
2 [tex]{}[/tex] 80%
3 [tex]{}[/tex] 80%
4 [tex]{}[/tex] 80%
5 [tex]{}[/tex] 40%
6 [tex]{}[/tex] 100%
7 [tex]{}[/tex] 80%
8 [tex]{}[/tex] 100%
9 [tex]{}[/tex] 80%
10 [tex]{}[/tex] 80%
Therefore, the sum of the percentages outcome the days Ginger eats pizza = 0.8 + 0.8 + 0.8 + 0.8 + 0.4 + 1 + 0.8 + 1 + 0.8 + 0.8 = 8
The number of runs of simulation = 10 runs
The estimated probability that Ginger will eat a a pizza everyday of the week = (The sum of the percentages outcome the days Ginger eats pizza)/(The number of runs of simulation)
∴ The estimated probability that Ginger will eat a a pizza everyday of the week = 8/10

Find the 44th term.
PLZ HELP
answer : 226
difference : 5
‘0th’ term : 6
rule : 5n + 6
if n = 44
220 + 6 = 226
Answer:
a₄₄ = 226
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 16 - 11 = 21 - 16 = 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = 5 , then
a₄₄ = 11 + (43 × 5) = 11 + 215 = 226

What is an equation in point-slope form for the line that contains the points (-1, 4) and (11, -6)?
Answer:
The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]
Step-by-step explanation:
Given points are;
(-1, 4) and (11, -6)
We will find the slope of the line through the given points.
Slope = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{-6-4}{11-(-1)}[/tex]
m = [tex]\frac{-10}{12}[/tex]
m = [tex]\frac{-5}{6}[/tex]
Point slope form of a line is given by;
[tex]y-y_1=m(x-x_1)[/tex]
Putting the point (-1,4) and slope in the equation
[tex]y-4=-\frac{5}{6}(x-(-1))\\y-4 =-\frac{5}{6}(x+1)[/tex]
Hence,
The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]

predicted to buy two or more pairs? If 107 customers buy more than two pairs,
did more customers than normal buy two or more pairs?
Answer:
84 Customers

2) Solve each problem with right angle at C:.
a) Find all sides and angles when B = 67º and c=16.
b) Find all sides and angles when b= 2 and c=6
Answer:
Step-by-step explanation:
a.)
<A = 90 - 67 = 23* A = (a^2 + 14.72^2 = 16^2) = a = 6.25
<B = 67* B = (sin67 = b/16) = sin67*16 = 14.73
<C = 90* C = 16
b.)
a = (a^2 + 2^2 = 6^2) = a = 5. 66 <A = (cosA = 2/6) = 70.53*
b = 2 <B = 90-70.53 = 19.47*
c = 6 <C = 90*

Which expression can you use to find the total price of 5 concert tickets
(from Iready)
Answer:
5t + 2
Step-by-step explanation:
Given that :
Total cost of ticket = t + 2
t = price of one ticket ; the constant digit, '2' is the service fee.
The service fee being a constant amount during the purchase of concert ticket will be paid per service transaction done.
To purchase 5 concert ticket, total cost will be :
Ticket price for 5 tickets plus a service fee
5 * ticket price plus a constant service fee
5 * t + 2
5t + 2
