A large company put out an advertisement in a magazine for a job
opening. The first day the magazine was published the company got 90
responses, but the responses were declining by 10% each day.
Assuming the pattern continued, how many total responses would the
company get over the course of the first 19 days after the magazine was
published, to the nearest whole number?
Answer:
C(19)=12 responses
Step-by-step explanation:
Exponential Decay Function
The exponential function is frequently used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function can be expressed as follows:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The company puts out an advertisement for a job opening. Initially, the company got 90 responses to the advertisement. Each day, the responses declined by 10%.
This is an example where the decay model can be used to calculate the responses to the advertisement at the day t.
The initial value is Co=90, the decaying rate is r=10% = 0.10. The model is written as:
[tex]C(t)=90\cdot(1-0.1)^t[/tex]
Calculating:
[tex]C(t)=90\cdot(0.9)^t[/tex]
We are required to calculate the number of responses at day t=19, thus:
[tex]C(19)=90\cdot(0.9)^{19}[/tex]
C(19)=12 responses

(Sin 5A - Sin 7A - Sin 4A + Sin 8A)÷
(Cos 4A - Cos 5A - Cos 8A + Cos 7A)=
Cot 6A
We use a similar strategy as in your previous question. Rewrite:
sin(5x) = sin(6x - x) = sin(6x) cos(x) - cos(6x) sin(x)
sin(7x) = sin(6x + x) = sin(6x) cos(x) + cos(6x) sin(x)
→ sin(5x) - sin(7x) = -2 cos(6x) sin(x)
sin(4x) = sin(6x - 2x) = sin(6x) cos(2x) - cos(6x) sin(2x)
sin(8x) = sin(6x + 2x) = sin(6x) cos(2x) + cos(6x) sin(2x)
→ sin(8x) - sin(4x) = 2 cos(6x) sin(2x)
cos(5x) = cos(6x - x) = cos(6x) cos(x) + sin(6x) sin(x)
cos(7x) = cos(6x + x) = cos(6x) cos(x) - sin(6x) sin(x)
→ cos(7x) - cos(5x) = -2 sin(6x) sin(x)
cos(4x) = cos(6x - 2x) = cos(6x) cos(2x) + sin(6x) sin(2x)
cos(8x) = cos(6x + 2x) = cos(6x) cos(2x) - sin(6x) sin(2x)
→ cos(4x) - cos(8x) = 2 sin(6x) sin(2x)
Then
(sin(5x) - sin(7x) - sin(4x) + sin(8x)) / (cos(4x) - cos(5x) - cos(8x) + cos(7x))
= (2 cos(6x) sin(2x) - 2 cos(6x) sin(x)) / (2 sin(6x) sin(2x) - 2 sin(6x) sin(x))
= (2 cos(6x) (sin(2x) - sin(x))) / (2 sin(6x) (sin(2x) - sin(x)))
= cos(6x) / sin(6x)
= cot(6x)

What is the image of (6,5) under a counterclockwise
rotation of 180°?
Answer:
(-6, -5)
Step-by-step explanation:
For a rotation of 180 degrees no matter the direction, you just flip the sign. In (6, 5) both are positive so you just change them to a negative.

a number was subtracted from 7 and that difference was the divided by 2. after which the quotient was multiplied by 4. this product was 4. what was the difference
Answer:
Difference is 9-7 = 2
Given number is 9
Step-by-step explanation:
Assume;
Given number is x
So,
Subtracted from 7;
x - 7
Divided by 2
(x-7)/2
Multiplied by 4
[(x-7)/2]4
Product was 4
[(x-7)/2]4 = 4
x-7 = 2
x = 9
Given number is 9
Difference is 9-7 = 2

A cube has a side length of 8 inches. Select all values that represent the cubes volume in cubic inches. A. 8^2 B. 8^3 C. 6 x 8^2 D. 6 x 8 E. 8 x 8 x 8
Answer: B. 8^3; E. 8 x 8 x 8
Step-by-step explanation:
From the question, we are informed that a cube has a side length of 8 inches.
To calculate the volume of a cube, we multiply the length given thrice. In this case, the length of the cube is 8 inches. Therefore, its volume will be:
= 8^3
= 8 × 8 × 8
= 512 inches cubed
Therefore, the correct options are:
B. 8^3
E. 8 x 8 x 8

C. 9
D. 13 1/2.
Answer: D. 13 1/2.
Step-by-step explanation:
1/2*3= 1 1/2 cups of dishwashing liquid.
4 1/2*3= 13 1/2 cups of water will be used with 1 1/2 cups of dishwashing liquid.
Priya noticed in the last activity that between the 2 triangles, you only need to know 4 angles to show that they are similar. She wondered which fourth angle would work to prove that triangle RST is similar to triangle EFG. Draw a sketch of the triangle. Then pick one angle measurement that would prove the triangles are similar. Explain to Pyria why knowing that angle would be enough.
Answer:
Please find attached a drawing of the triangles ΔRST and EFG showing the angles
The angle on ΔEFG that would prove the triangles are similar is ∠F = 25°
Step-by-step explanation:
In order to prove that two triangles are similar, two known angles of each the triangles need to be shown to be equal
Given that triangle ∠R and ∠S of triangle ΔRST are 95° and 25°, respectively, and that ∠E of ΔEFG is given as 90°, then the corresponding angle on ΔEFG to angle ∠S = 25° which is ∠F should also be 25°
Therefore, the angle on ΔEFG that would prove the triangles are similar is ∠F = 25°.
Explain how to use the distributive property to find the product (3) 4 1/5
Answer:
[tex]\frac{63}{5}[/tex]
Step-by-step explanation:
Given expression:
(3) 4[tex]\frac{1}{5}[/tex]
The distributive law is mostly applied to multiplication and division which helps to expand a parentheses;
4[tex]\frac{1}{5}[/tex] can be written as [tex]\frac{21}{5}[/tex]
Now;
(3) [tex]\frac{21}{5}[/tex]
With distributive property, we simply multiply the two terms;
3 x [tex]\frac{21}{5}[/tex] = [tex]\frac{63}{5}[/tex]
Answer:
Rewrite 3 ( 4 1 /5 ) as 3 ( 4 + 1 5 ) . Distribute the 3 to get 3(4) + 3 ( 1 /5 ) . Multiply to get 12 + 3 /5 . Then add to get 12 3 /5

what is 250 to 400 in percentage
Answer:
60%
Step-by-step explanation:
:))))))
step 1 Address the formula, input parameters & values
Formula :
Increase
Initial Value
x 100 = Percent Increase (%)
Initial Value X = 250 & New Value Y = 400
Increase = (Y - X)
(400 - 250)
250
x 100 = ?
step 2 Apply the values in the percentage increase {(Y - X)/X x 100} formula
=(400 - 250)
250
x 100
=150
250
x 100
= 60%
(400 - 250)
250 x 100 = 60%
60 percent increase (%↑) or raise from 250 is 400 or 160% of 250 is 400
Answer:
62.5%
Step-by-step explanation:
Divide 250 by 400 to get 0.625. Then, multiply by 100 to get the percentage, 62.5%.
