Which equation would represent exponential decay?
a. f (x) = 4(1.03)^x
b. f (x) = -2x - 5
c. f (x) = -3(1.02)^x
d. f (x) = 2(.87)^x
Answer:
D
Step-by-step explanation:
The .87 represents that the new value is 87% of the previous value, thus decaying exponentially. B decays linearly and the other two are exponential growth functions.

How do I find out the answer for this equation?
1/72 x 648
Answer:
The answer is 9
Step-by-step explanation:
Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying
[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.

What is the volume of the following shape?
Answer:
[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]
Step-by-step explanation:
We can divide it into two parts:
First, we can fin the volume of the parallelepiped:
h1 = 16 cm
w1 = 2 cm
d1 = 3 cm
[tex]V_{1}=h_{1}*w_{1}*d_{1}=16*2*3=96\: cm^{3}[/tex]
Now, the volume of the second parallelepiped is:
h2 = (8-2) cm = 6 cm
w2 = 2 cm
d2 = 3 cm
[tex]V_{2}=h_{2}*w_{2}*d_{2}=6*2*3=36\: cm^{3}[/tex]
Finally, the total volume will be the addition of these two volumes.
[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]

How many 1 \5 are in 9?
Answer:
45/5 or 45
Step-by-step explanation:
5x9=45 45/9=9
so therefore there are 45 , 1/5 in 9
The number of times a fraction number 1/5 is present in the integer number 9 will be 45 times.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The number of times a fraction number 1/5 is present in the integer number 9 is calculated by the division of the number 9 by the fraction number 1/5. Then we have
⇒ 9 / (1/5)
⇒ 9 x 5
⇒ 45
The number of times a fraction number 1/5 is present in the integer number 9 will be 45 times.

the pot is left over?
Answer: 3/4
Step-by-step explanation:
1/6 = 2/12
2/12 + 1/12 (the brother and the mom’s pieces) = 3/12->1/4
1 - 1/4 =3/4
The supplement of an acute angle is an obtuse angle. True or false?
Vertical angles are always supplementary. True or False?
Answer:
yes, it is true because a supplimentary angle is 180 degrees and if their is an acute angle then it is less than 90 degrees which means you subtract that by 180 and you get a number over 90 and an obtuse angle is over 90 which means the other side of the acute angle is obtuse. And the suppliment to an acute angle is always over 90 degrees

Step-by-step explanation:
Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6) Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%

4. 2 1/2
Step-by-step explanation:
1. You subtract 8-3/4=7 1/4
2. You have to add 2 3/4 hour + 1/2 an hour = 3 1/4 hours
3. You take 3 2/6 - 2/3= to make it easier you want to change the fractions so there the same denominator 2/6->1/3 now it will be much easier to subtract 3 1/3-2/3= 2 2/3
4. Finally you do 8-5 1/2 =2 1/2

11. Trey decides to consolidate his debt and
qualities for a personal loan of $10,000 to help
pay off his current credit. He qualities for an
interest rate of 4.29% and is choosing between
a term of 5 or 10 years.
RATE
TERM
MONTHLY PAYMENTS
4.29%
5 years
$185.48
4.29%
10 years
$102.63
Which term will result in the lowest total
repayment, and how much lower will the
repayment be?
A. The 5-year term would be $1,128.80 lower.
B. The 5-year term would be $1,186.80 lower
C. The 10-year term would be $2,315.60 lowe
D. The 10-year term would be $1,186.80 lowe
Answer:
B. The 5-year term would be $ 1,186.80 lower
Step-by-step explanation:
The repayment parameters of the $10,000 loan Trey qualifies for are given as follows;
The loan interest rate = 4.29%
The monthly payments for the 5 year loan term = $185.48
The monthly payments for the 10 year loan term = $102.63
The total repayment amount for the 5 year loan term, '[tex]A_{5 \ years}[/tex]' is given as follows;
[tex]A_{5 \ years}[/tex] = $185.48 × 5 × 12 = $11,128.8
While the total repayment amount for the 10 year loan term, '[tex]A_{10 \ years}[/tex]' is given as follows;
[tex]A_{10 \ years}[/tex] = $102.63 × 10 × 12 = $12,315.6
The difference between the total repayment for the 10-year term and the 5-year term loan, [tex]A_{10 \ years}[/tex] - [tex]A_{5 \ years}[/tex], is given as follows;
[tex]A_{10 \ years}[/tex] - [tex]A_{5 \ years}[/tex] = $12,315.6 - $11,128.8 = $1,186.80
Therefore, the 5-year term is lower than the 10-year term by $1,186.80
Marks books has an area of 48 in.². The perimeter of the book is 52 inches. what are the dimensions of the book
Answer:
dimensions of the book are 2 in. by 24 in.
Step-by-step explanation:
I assume the book is a rectangle
Let w = the width
l = the length
A = lw = 48 P = 2w + 2l = 52
w + l = 26
l = 26 - w
w(26-w) =48
26w - [tex]w^{2}[/tex] = 48
[tex]w^{2} - 26 w + 48 = 0[/tex]
(w-2)(w -24) = 0
w = 2 or w = 24
if w = 2, then l = 26 - 2 = 24
if w = 24, then l = 26 - 24 = 2
So, the dimensions of the book are 2 in. by 24 in.

What is the area of the polygon in square units?
Answer:
(d) 80 square units
Step-by-step explanation:
As with many composite area problems, this can be worked any of several ways. The attached shows trapezoid ABCE, from which triangle CDE can be removed to get the desired area.
The relevant formulas are ...
A = (1/2)(b1 +b2)h . . . . . . area of a trapezoid
A= (1/2)bh . . . . . . . . . . . . area of a triangle
__
Here, the trapezoid has bases 12 and 2, and height 12, so its area is ...
A = (1/2)(12 +2)(12) = 84 . . . . square units
The triangle has a base of 4 and a height of 2, so its area is ...
A = (1/2)(4)(2) = 4 . . . . square units
Then the area of the desired figure is ...
84 - 4 = 80 . . . . square units

If the ratio of two numbers is9:2and their difference is 63 .Find the two numbers
Answer:
The two numbers are 18, and 81.
step-by-step explanation:
If you divide both sides of the ratio by 2 to get 4.5/1, you can then graph that as y=4.5x, finally you just find two numbers that have a difference of 63, which in this case is 18, and 81.

2g−(−1)=3
Step 1: Simplify both sides of the equation.
2g+1=3
Step 2: Subtract 1 from both sides.
2g+1−1=3−1
2g=2
Step 3: Divide both sides by 2.
2g/2 = 2/2
g=1

Answer:
The two trains are closing the initial distance between that of 280 miles by the sum of their two speeds. 80mph + 60mph = 140 mph. With the speed that the distance between the trains is closing, we can divide the starting distance to find out the number of hours until the trains pass. 280 miles / 140 mph = 2 hours. Since the trains left at 3:00 and will pass each other in 2 hours, they will pass each other at 5:00.
