Exponential equation has tow major types
exponential decay
f(x) = a(1.16)^xexponential growth
f(x) = a(0.84)^xWhat are exponential equation?Exponent-based equations in which the exponent or a portion of the exponent is a variable are known as exponential equations.
This is a type of function that are of 3 main parts
the starting or initial value
base function
the exponents
Atypical example includes: f(x) = 300(1.16)^x
the starting = 300
the base = 1.16
the exponents = x
A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decay or exponential growth, and so forth.
The base is what determines exponential growth or decay

On Wednesday 72% of the customers who bought gas at a gas station also bought a hot dog. There were 25 customers in all who bought gas.
Answer:
18 People bought hot dogs
Step-by-step explanation:
The question is not complete, but I’m assuming you need the number of people who bought hot dogs.
25 customers bought gas.
72% of them also bought a hot dog.
So thE number of customers who bought hot dogs are 72% of 25
=> 72/100 * 25
=> 0.72 * 25
= 18 people

In two similar triangles find the ratio of corresponding sides if the areas are 50cm²and 98cm²
Answer:
5:7
Step-by-step explanation:
The areas of two triangles are 50cm²and 98cm².
We need to find the ratio of corresponding sides. It can be calculated as follows :
[tex]\dfrac{s_1}{2_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{50}{98}}\\\\=\sqrt{\dfrac{25}{49}}\\\\=\dfrac{5}{7}[/tex]
So, the ratio of corresponding sides are 5:7.
A mountain climber took 2 minutes to rappel down 60 feet. Which equation shows the correct calculation to show his movement per minute?
Answer:
–60 ÷ 2 = –30
Step-by-step explanation:
Calculation to determine the equation that shows the correct calculation to show his movement per minute
Using this formula
Speed rate = Distance / Time
Where,
Distance=-60 ft
Time =2 min
Let plug in the formula
Speed rate = -60 ft /2 min
Speed rate = -30
Based on the information given we were told that the climber rappel DOWN which is why the distance was negative.
Therefore the equation that shows the correct calculation to show his movement per minute is –60 ÷ 2 = –30

George tells you that when variables are in the denominator, the equation
2/3+5/x=8/9 becomes unsolvable. George explains, "There is a value for x that makes the denominator zero, and you can't divide by zero." Demonstrate to George how the equation is still solvable and explain your reasoning.
Answer:
X can equal 22.5
Step-by-step explanation:
I've set up the equation below:
[tex]\frac{2}{3} +\frac{5}{x} =\frac{8}{9}[/tex]
With this equation, as any addition equation goes, we assume it to be like this:
A + B = C
so
C - A = B
that means,
[tex]\frac{8}{9} -\frac{2}{3} =\frac{5}{x}[/tex]
The easiest thing to do is to make 2/3 have the same denominator as 8/9, we do this by...
[tex]\frac{2}{3} *\frac{3}{3} = \frac{6}{9} \\[/tex]
So...
[tex]\frac{8}{9} -\frac{6}{9} =\frac{2}{9} =\frac{5}{x}[/tex]
We now know that 5 over x equals 2 over nine. We can determine x by cross multiplying as follows:
[tex]\frac{5}{x} =\frac{2}{9} \\2x = 45\\x=22.5[/tex]
So, x is 22.5, making the equation indeed solvable.

D). 280.65
(I'd really appreciate it if you could show me how you got your answer and why it works like that. I'm a bit stumped on how to do this part)
A ten-minute mile is 62% of a factor so you'd use this mans weight and then multiply it by .62. (174)(0.62)=107.88

Gerald has a bag of 10 colored balls: 3 green, 3 red, and the rest yellow. He randomly draws two balls, one at a time without replacement. Find the probability of drawing at least one yellow ball.
Answer:
2/3
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that there are 10 balls of which 3 green, 3 red, and the rest yellow
Number of yellow balls = 10 - 3 - 3 = 4
Probability of picking a;
Green ball = 3/10
Red ball = 3/10
Yellow ball = 4/10
If two balls are picked without replacement, the probability that one is at least yellow will be

Look at the two-dimensional net shown.
A rectangular pyramid. The rectangular base has a length of 10 meters and height of 3 meters. 2 triangular sides have a base of 10 meters and height of 6.4 meters. 2 triangular sides have a base of 3 meters and height of 8 meters.
Which statements are true?
Check all that apply.
The solid formed by the net will be a rectangular pyramid.
The solid formed by the net will be a square pyramid.
All four triangular faces have an area of 12 m2.
There are two sets of opposite congruent triangular faces.
The base has an area of 30 m2.
Answer: Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.
Step-by-step explanation: The volume of pyramid A is TWICE the volume of pyramid B.
If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),
V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³
The new volume of pyramid B is EQUAL to the volume of pyramid A.
Line d is parallel to line c in the figure below.
Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6.
Which statements about the figure are true? Select three options.
A.Vertical angles prove that Angle 2 is congruent to angle 5.
B. In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
c. Vertical angles prove that Angle 3 is congruent to angle 6.
D.The triangles are similar because alternate interior angles are congruent.
E.In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
F.The triangles are similar because corresponding sides are congruent.

Answer:
m<QPR = 25
Step-by-step explanation:
The sum of <RPS and <QPR make up 40 so:
8x + 7 + 9x + 16 = 40
17x + 23 = 40
17x = 17
x = 1
m<QPR:
9x + 16

Mr. Martin had 7 eggs. He used half (½) of these eggs plus one-half (½) another egg to make an omelet. He then used half (½) of what was left plus half (½) another egg to make a batch of cookies. Finally, he used half (½) of what was left plus one-half (½) an egg to make a meatloaf.
Answer:
Number of eggs used to make meat loaf = 1
Step-by-step explanation:
The total number of eggs used to make omelet =
[tex]\frac{7}{2} + \frac{1}{2}\\\frac{8}{2} \\4[/tex]
The total number of eggs used for making cookies
[tex]\frac{3}{2} + \frac{1}{2} \\\frac{4}{2}\\2[/tex]
He is now left with 7 -4-2 = 1 egg only
So he uses this one egg to make meat loaf
