Answer:
For any exponential function in which the base is less than 1, it will be an exponential decay situation. In this problem, the base is 0.97. The amount that the base is less than 1 ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.
Step-by-step explanation:
The formula for exponential decay is y=a(1-r)x.
r is the decay rate.

Hope I helped!
The solution is Option G.
The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 2/3 ) x 15% x 2000 be equation (1)
On simplifying the equation , we get
A = ( 2/3 ) x ( 15/100 ) x 2000
A = ( 2/3 ) x ( 15 ) x ( 20 )
On further simplification , we get
A = ( 2/3 ) x 300
A = 2 x 100
A = $ 200
Therefore , the value of A is $ 200
Hence , the equation is A = $ 200

9514 1404 393
Answer:
7 1/8 yd
Step-by-step explanation:
The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.
P = 3·(2 3/8 yd) = 6 9/8 yd . . . . . 9/8 = 1 1/8
P = 7 1/8 yd
The perimeter is 7 1/8 yards.

Answer:
y less than or equal to 2x+1
Step-by-step explanation:
Move the slope to the other side and cancel the 4 on the y to get only y. Whatever you do on one side you must do on the other.
Answer:
y≤2x+1
Step-by-step explanation:
slope intercept form= y=mx+b
-8x+4y<=4
-8x+4y≤4
Add 8x to both sides
4y≤8x+4
Divide both sides by 4.
y≤2x+1

Jane spends about 1/6 of the day sleeping. How many hours in a day does Jane sleep? How many hours in a week?
Answer:
Jane spend 4 hours in a day sleeping, and 28 hours in a week.
Step-by-step explanation:
In 1 day, there are 24 hours. 24 multiplied by 1/6 is 4. I know this because 24 x 1/6 = 24/1 x 1/6 = 24/6 = 4/1 = 4.
In 1 week, there are 168 hours. 1/6 multiplied by 168 is 28. I know this because 168 x 1/6 = 168/1 x 1/6 = 168/6 = 28/1 = 28

The Maxwell family goes out for dinner. The price for the
meal is $90. The sales tax on the meal is 7.25% and they
also want to leave an 18% tip. What is the total cost of the
meal?
Answer:
$113.90
Step-by-step explanation:
Find the cost of the meal with sales tax:
90 x 0.075 = 6.525
Add that to the original cost of the meal:
90 + 6.525 = 96.525
Find the cost of the tip:
96.525 x 0.18 = 17.3745
Add the tip to the meal price:
96.525 + 17.3745 = 113.8995

GIVING 50 POINTS AND BRAINALIST FOR DA RIGHT ANSWER >:>Jordan has 300 pieces of candy. He gives Adrian ¼ pieces, 10% was given to Darien and he gave his little brother 25 pieces. Explain in writing (typing) how to find the number of pieces each person received then explain in writing (typing) how to find the number of pieces Jordan has left. (Remember to write 5 or more complete sentences)
Answer:
170 pieces leftStep-by-step explanation:
There are total 300 pieces of candy.
Adrian gets 1/4 of total
Multiply the total number by 1/4, to find the number Adrian gets:
300*1/4 = 75Darien gets 10% of total.
10% is equal to 10/100 = 1/10. Multiply 300 by 1/10 to get the number Darien gets:
300*1/10 = 30The little brother gets 25 pieces.
Number of pieces Jordan has given:
75 + 30 + 25 = 130Number of pieces left:
300 - 130 = 170 pieceswhich equation is true? 0.9 = 9/100 , 1.9 = 9/100 , 12/10 = 1.2 , or 18/9 = 0.2?
Answer:
12/10=1.2
Step-by-step explanation:
You just move the decimal one place value to the left. so 12÷10=1.2 which is the same as 12/10=1.2

If f(x) = 5 + 4(x - 4)?,
what is f(7)?
Answer:
Let's solve for f.
x=5+4(x−4)f(7)
Step 1: Flip the equation.
28fx−112f+5=x
Step 2: Add -5 to both sides.
28fx−112f+5+−5=x+−5
28fx−112f=x−5
Step 3: Factor out variable f.
f(28x−112)=x−5
Step 4: Divide both sides by 28x-112.
f(28x−112)28x−112=x−528x−112
f=x−528x−112
Answer:
f=x−528x−112

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c:c = 39.95 + 0.15(s + r)If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.

Step-by-step explanation:
Forty-five percent of households say they would feel secure if they had​ $50,000 in savings. You randomly select 8 households and ask them if they would feel secure if they had​ $50,000 in savings. Find the probability that the number that say they would feel secure is​ (a) exactly​ five, (b) more than​ five, and​ (c) at most five.
Answer:
0.172 ; 0.0884 ; 0.9115
Step-by-step explanation:
Proportion or those who feel secure, p = 0.45
Sample size, n = 8
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
A.) p(x = 5)
P(x =5) = 8C5 * 0.45^5 * 0.55^3
P(x = 5) = 56 * 0.0184528125 * 0.166375
P(x = 5) = 0.1719248540625
P(x = 5) = 0.172
B.) P(x > 5)
P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)
P(x > 5) = 0.0703 + 0.0164 + 0.0017
P(x > 5) = 0.0884
C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)
Using the binomial probability calculator to obtain a direct solution :
P( ≤ 5) = 0.9115
A bank offers an annual simple interest rate of 6% on home improvement loans. How much would Tobias OWE IN ALL if he BORROWED $12,000 over a period of 3 years?
Answer: $14160
Step-by-step explanation:
Simple interest would be calculated as:
= PRT/100
where,
P = Principal = $12000
R = Rate = 6%
T = Time = 3 years
Simple interest = ($12000 × 6 × 3)/100
= $216000/100
= $2160
The amount that Tobias owe in all would be:
= $12000 + $2160
= $14160
Solve for x.
(x + 5)(x + 4) = 9x + 141
Answer: x=11 or x=-11
Step-by-step explanation:
Answer:x=11 or x=-11
Step-by-step explanation: First, Use the FOIL method.
(x+5)(x+4)=9x+141
First: [tex]x^{2}[/tex]
Outer: 4x
Inner: 5x
Last: 5x4=20
Combine Like terms and write in standard form: [tex]x^{2}[/tex]+9x+20
Set up new equation:[tex]x^{2}[/tex]+9x+20=9x+141
Subtract 9x from both sides: [tex]x^{2}[/tex]+20=141
Subtact 20 from both sides: [tex]x^{2}[/tex]=121
Sqr root 121: [tex]\sqrt{121}[/tex] =11
Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11
