Below is the graph of a trigonometric function. It has a maximum point at
(1/4pi,-2.2)
and a minimum
point at
(3/4pi,-8.5) what is the amplitude
Answers
Step-by-step explanation:
Amplitude is the distance between the center line of the function and the top or bottom of the function.
The amplitude is half the distance between the max and the min, so
Amplitude = 1/2(max - min)
Amplitude = 1/2(-2.2 -(-8.5))
So amplitude = 1/2(6.3)
= 3.15

D.

Answers
The Consumer Price Index for the year 2 be 116.11.
How do we calculate Consumer Price Index?This is calculated by adding together a sampling of product prices from a previous year.
We then add together the current prices of the same products and divide the total of current prices by the old prices, then multiply the result by 100.
Given data
Year 1 = $9
Year 2 = $10.45
Year 2 / Year 1 = $10.45 / $9.00
Year 2 / Year 1= 1.6111
CPI for year 2 = 1.61 x 100
CPI for year 2 = 116.11
Therefore, the Option D is correct.

Write an equation modeling the change in elevation c after s seconds.
Answers
Answer:
c=-2.5s
Step-by-step explanation:
The equation modeling the change in elevation c after s seconds is
c = -2.5s
Given,
A mountain climber descends a cliff at a rate of 2.5 ft/second.
We need to write an equation modeling the change in elevation c after s seconds.
How do we represent elevation and descent?Elevation means going up so we take it as a positive distance.
Descent means going down so we take it as a negative distance.
Find the rate at which the climber descents.
2.5 ft = 1 second
Find the equation that represents the descents c in seconds.
We have,
2.5 ft = 1 second
So,
s x 2.5 ft = s x 1 seconds
2.5 s ft = s seconds
This means,
In s seconds we will have a 2.5s distance descended.
We can write this as an equation:
c = change in elevation
c = - 2.5s
Thus the equation modeling the change in elevation c after s seconds is
c = -2.5s

Kylie found 25 rolls of indigo ribbon and teal ribbon. Each roll of indigo ribbon was 1 meter long and each roll of teal ribbon was 4 meters long. If Kylie found 64 meters of ribbon in total, how many rolls of each color did she find?
Answers
Given
No.of green ribbon rolls used=4
No.of purple ribbon rolls used=8
Length of ribbon in one green roll=90 feet
Length of ribbon in one purple roll=60 feet
In order to find the difference in total green and purple ribbon used, we have to calculate the total length of the ribbons used.
Total length of green ribbon=Number of rolls*length of ribbon in one roll
=4*90
=360 feet
Total length of purple ribbon=number of rolls*length of ribbon in one roll
=8*60
=480 feet
The difference between the total length of green ribbon and purple ribbon=480-360
=120 feet ..

If their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.
Taxable incomea. Taxable income:
Taxable income=Gross income - Total taxes due

WHO CAN FILL IN THE VALUES OF THE TABLE. i dont understand. please, please help.
If you can also tell me what "employment-to-population ratio" is, what "labor force participation rate" is, "unemployment rate" all using the values of the table, i will make you brainiest.
Answers
Answer:
Total Population = Young & Institutionalized + Working Age Population
Working-Age Population = Labor Force + Not in the Labor Force
Labor Force = Employed + Unemployed
Total population = 400
Working Age Population = 300
Young & Institutionalized = 100
Not in Labor Force = 100
Labor Force = 200
Employed = 150
Unemployed = 50
Employment-population ratio = (Employed ÷ Working Age Population) x 100%
= (150 ÷ 300) × 100%
= 50%
Labor force participation rate = (Labor Force ÷ Working Age Population) x 100%
= (200 ÷ 300) × 100%
= 66.7% (nearest tenth)
Unemployment rate = (Unemployed ÷ Labor Force) x 100%
= (50 ÷ 200) x 100%
= 25%

explain why it takes more 1/9s than 1/6s to make a fraction equivalent to 1/3
Answers
Answer:
1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3
It takes more 1/9 than 1/6 to make a fraction equivalent to 1/3.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To make a fraction equivalent to 1/3, we need to multiply both the numerator and the denominator by the same non-zero constant. Let's call this constant "x". Therefore, the equivalent fractions are:
1/3 = (x1)/(x3)
To compare how many 1/9s and 1/6s are needed to create this fraction, we need to find the value of "x" that will make the denominators of 1/9 and 1/6 equal to the denominator of 1/3, which is 3.
For 1/9, we can find x as follows:
1/9 = (x1)/(x9)
Multiplying both sides by 3, we get:
3/9 = (x3)/(x9)
Simplifying, we get:
1/3 = x/9
Multiplying both sides by 9, we get,
x = 3
Therefore, to make a fraction equivalent to 1/3 using 1/9, we need to multiply both the numerator and denominator by 3.
Now let's look at 1/6. We can find x as follows:
1/6 = (x1)/(x6)
Multiplying both sides by 2, we get:
2/12 = (x2)/(x12)
Simplifying, we get:
1/6 = x/12
Multiplying both sides by 12, we get:
x = 2
Therefore, to make a fraction equivalent to 1/3 using 1/6, we need to multiply both the numerator and denominator by 2.
