An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.
Answer:
The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]
Step-by-step explanation:
Exponential equation:
An exponential equation has the following format:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which A(0) is the starting value and r is the growth rate, as a decimal.
Starting value of 13 and a growth rate of 0.78%.
This means that [tex]A(0) = 13, r = 0.0078[/tex]
Write an equation to model the situation.
[tex]A(t) = A(0)(1+r)^t[/tex]
[tex]A(t) = 13(1+0.0078)^t[/tex]
[tex]A(t) = 13(1.0078)^t[/tex]
The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]
Hafiz has $25. His sister has 1/5 as much as Hafiz. His father has 40% as much as Hafiz. Calculate how much money Hafiz, his sister and his father have in total.
please answer it
Answer:
Step-by-step explanation:
According to question, we know that
His Sister has "1/5*$25 which is equal to $5, and his father has "40%*$25 which is equal to 0.4 * $25 = $10". So, the money Hafiz, his sister and his father have in total
= $25+$5+$10 = $40
Hafiz = $25
Sister = [tex]\frac{1}{5}[/tex]
Father = 40%
FindTotal money of Hafiz, Sister, and Father altogether.
SolutionSister[tex]\frac{1}{5} X[/tex] $25
= $5
Father40% (0.4) x $25

Answer: why do we even need math
Step-by-step explanation:
If cos(2/3x+20)°=sin(2x−10)°, find the acute angles of the corresponding right triangle.
A =
B =
Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50

Last Saturday an accident caused a traffic jam 13 miles long on a stretch of the
interstate.
a. How many vehicles do you think were in the traffic jam if the average car's
length measures approximately 15 feet? Explain your thinking and show all
calculations.
b. Would there be more or less vehicles if you were told there were a large
number of SUVs and trucks present in this traffic jam? Explain your thinking and
show all calculations.
There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.
What is logical reasoning?Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.
Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.
13 miles = 68,640 feet
One car is of 15 ft
Let there be x cars,
15x = 68,640
x = 4576
Therefore, there are 4576 cars in traffic.
If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.
Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

58 is the difference of Janelle's height and 24.
Use the variable j to represent Janelle's height.
Answer:
Janelle's height is 82 units.
Step-by-step explanation:
Let j represent Janelle's height.
It is mentioned that, 58 is the difference between Janelle's height and 24.
Mathematically, we can write it as :
j-24 = 58
We can solve it as follows :
Adding 24 both sides,
j-24+24 = 58+24
j = 82
Hence, Janelle's height is 82 units.

Answer:
The answer is 36
When finding a percentage you would typically multiply the decimal. Example 20% of 100. Multiply 100 x 0.20 = 20
When trying to do the opposite you would do the inverse (opposite) operation. So the inverse (opposite) operation of mulitplication is division.
Example: 20% of what number w is 20? Divide 20/0.20 = 100
Okay now lets solve your problem!
25% of what number w is 9? Divide 9/0.25 = 36
Step-by-step explanation:
25% in decimal is 0.25
9 / 0.24 = 36

On solving the provided question, we can say that - the perimeter chest won't fit next to her bed, thus the answer is no.
What is a perimeter?The perimeter of a form is determined by the length of its contour. A rectangle or square's perimeter is determined by adding the widths of its four sides. In this instance, the rectangle's length and breadth are represented by x and y, respectively. The surface of a form is used to compute its area.
Given here is: In her room, it is 86 inches wide. The width of the bed is 76 inches.
She also wants to accommodate a chest of drawers that is 72 centimeters broad, which equals inches.
=> 90 cm = 24.6546536565 inches
and the space left in her room = 86-76=10 inches
thus, the chest will not fit next to her bed

What if I only know the length of the shorter side consider the triangle equilateral triangle than determine the values of n and m without using a calculator
Answer: An equilateral triangle is a three-sided polygon with three equal sides and three equal angles of 60 degrees each. If you know the length of one of the sides of an equilateral triangle, you can use the formula for the area of an equilateral triangle to determine the values of n and m. The formula for the area of an equilateral triangle is:
Area = (sqrt(3)/4) * s^2
where s is the length of one of the sides of the triangle.
To determine the values of n and m, you can rearrange the formula to solve for s. For example, if you know that the area of the triangle is n and the value of m is the length of one of the sides of the triangle, you can rearrange the formula to solve for s:
s = sqrt(4n/sqrt(3))
Then, you can use the value of s to determine the value of m.
Step-by-step explanation:
if each interior angle of a polygon is 144 . find the polygon
Answer:
Decagon
Step-by-step explanation:
Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees.
For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees.
Hence, the number of sides = the number of vertices = 360/36 = 10.
Answer. Your polygon is decagon with 10 sides (vertices).

Mark and Connie are insure for 80% of the replacement value of their home, which is valued at $245,000. How much is the policy amount on their house?
Answer:

Value of the home = $245000Insurance = 80%Policy amount:
$245000*80/100 = $196000Answer:
$196,000
Step-by-step explanation:
Given information:
Value of home = $245,000Insurance replacement percentage = 80%To find the policy amount on their house, find 80% of the value of the home:
[tex]\begin{aligned}\sf Policy\:amount & = \sf 80\%\:of\:245000\\\\& = \sf \dfrac{80}{100} \times 245000\\\\& = \sf \dfrac{80 \times 245000}{100}\\\\& = \sf \dfrac{19600000}{100}\\\\& = \sf 196000\end{aligned}[/tex]
Therefore, the policy amount on Mark and Connie's house is $196,000.
