A quantity with an initial value of 390 decays exponentially at a rate of 8.5% every 9 weeks. What is the value of the quantity after 42 days, to the nearest hundredth?
Answer:
Step-by-step explanation:
The initial value = 390
It decayed at an exponential rate of 8.5% for 9weeks which is also 63days
Decay exponential rate after 42days will be:
8.5% = 63days
x% = 42days
8.5% ×42days = 63days×x%
357 = 63x
x = 357/63
x = 5.666%
Hence after 42days it would have decayed by 5.666% of it initial value.
That is 5.666% of 390
5.666/100 × 390
0.056×390
= 22.0974
To the nearest hundredth 22.10
Hence the value left will be 390-22.0974
= 367.9026
To the nearest hundredth 367.90
Answer:
The answer is 367.57

joe deposits $1500 in an account that pays 3% annual interest compounded conitiniously how much will joe have in his account after 5 years
Answer:A = 1500e^(0.03 * 5) = 1500e^(0.15)
use definition of logarithm
0.15 = ln(A / 1500)
0.15 = ln(A) - ln(1500)
ln(A) = 0.15 + ln(1500) = 0.15 + 7.313220387 = 7.463220387
Step-by-step explanation:
The amount of money Joe would have in his account after 5 years is $1742.75.
Given the following data:
Principal, P = $1500Interest rate, R = 3%Time, T = 5 yearsTo determine the amount of money Joe would have in his account after 5 years.
Mathematically, an interest that is compounded continuously given by the formula:
[tex]A = Pe^{rt}[/tex]
Where:
A is the future valueP is the principal.r is the interest rate.t is the time in years.Substituting the given parameters into the formula, we have;
[tex]A = 1500 \times e^{0.03 \times 5}\\\\A = 8000 \times e^{0.15}\\\\A = 1500 \times 1.1618[/tex]
A = $1742.75

“A Wok in the Park” charges a $100 set-up fee plus $12.50 per person. “Chop Chop Catering” charges $15 dollars per person.
Write a equation in the form y=mx+b for both companies
Answer:
y = $100 + $1.50x
y = $15x
Step-by-step explanation:
Given that :
A Wok in the Park charges :
Setup fee =$100 ; per person = $12.50
Chop Chop Catering charges :
$15 per person
Writing equation for the amount charged by the 2 services in the form :
y = mx + c ;
A Wok in the Park ;
Setup fee =$100 = c = intercept ; per person = $12.50 = slope = m
y = $100 + $1.50x
Where x = number of persons. ; y = amount charged
Chop Chop Catering charges :
$15 per person
y = 0 + $15x
y = $15x
x = number of persons. ; y = amount charged ; intercept (c) = $0
Choose the correct description of each system of equations (Problems 2 & 3). F consistent and independent H consistent and dependent G inconsistent J inconsistent and dependent 2. X + 2y = 7 -2x – 4y = -14
Answer:
Dependent.
Step-by-step explanation:
The system of equations we got there is dependent. This is because they are both basically the same equation, so the graph of both of them is just the same. We can get one equation from the other:
x+2y=7
if we multiplied both sides of the equation by -2 we would get:
-2(x+2y)=-2(7)
-2x-4y=-14
This means that the system of equations will have infinitely many answers.

If AX) = x2 + 2x + 3, what is the average rate of change of AX) over the interval (-4, 6]? OA 51 B. 40 OC. 31 OD 20 OE 4
Answer:
E
Step-by-step explanation:
The average rate of change of A(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 4, 6 ] , then
f(b) = f(6) = 6² + 2(6) + 3 = 36 + 12 + 3 = 51
f(a) = f(- 4) = (- 4)² + 2(- 4) + 3 = 16 - 8 + 3 = 11 , thus
average rate of change = [tex]\frac{51-11}{6-(-4)}[/tex] = [tex]\frac{40}{10}[/tex] = 4 → E

To get the perimeter, you add all the lengths of the sides together.
To get the area, you do A=hb * b / 2, which is 60
Answer:
The answer is at the bottom!!
Step-by-step explanation:
A= b * h * 1/2
24 * 5 =120
120 / (1/2)=60
60= 24 * 5 * 1/2
P = a + b + c
P= 13 + 24 + 13
P=50

(4x-1) /2=x+7
4x-1 all over 2 = x +7
Answer:
x = [tex]\frac{15}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x-1}{2}[/tex] = x + 7 ( multiply both sides by 2 to clear the fraction )
4x - 1 = 2(x + 7) ← distribute
4x - 1 = 2x + 14 ( subtract 2x from both sides )
2x - 1 = 14 ( add 1 to both sides )
2x = 15 ( divide both sides by 2 )
x = [tex]\frac{15}{2}[/tex]

An artist uses 18 colors on an art palette to paint a picture. This is 72% of all the colors on the palette. How many colors are on the artist’s palette?
Answer:
He actually has 25 paints.
Step-by-step explanation:
This is because you take 18x100(100 is the total % under 72 because 72 is out of 100) that equals 1800. then, you take 1800 and divide it by 72. That is because 72 is the actual number that we already have. You would get 25 after dividing. hope this helps:)
Answer:
25
Step-by-step explanation:
Think the number is x
So
According to the question
The equation is
x×72%=18
x×72/100=18
x×18/25=18
x=18×25/18
x=25
So
There are 25 colours on the artist's palette
