we have the function
Part a
For t=7
substitute in the given function
For t=14
For t=21
For t=28
For t=35
Observation: The values of E varies from -1 to 1, including the zero
Part B
Remember that
The Period goes from one peak to the next
so
Period=2pi/B
B=pi/14
Period=(2pi)/(pi/14)=2pi*14/pi=28
<h2>the period is 28 days</h2>
1.)
Old Number:35
New Number:45
Now, subract the new number(45) from the old number. (35)
45-35 is 10. Now divide the old number (35) by 10.
You'll get 3.5. 3.5%, increase is the answer for #1.
2.) Old: s (students)
New: 36,750
Do 100+5 (Addition because we do not know what the old number is.) 100+5 is 105. Move decimal over twice and you get 1.05. Multiply 36,750 by 1.05.
There were 38,587.5 kids last year.
3.)Since the discount is 15% off, do 100-15=85. Now, move the decimal over from the percent, and that makes that .85. Now multiply 50x.85. You get 42.5, or $42.50. Now the coupon is 10%, So subtract 100-10, giving you 90. Now move the decimal over. .90. Multiply 42.5 (or 42.50) by .90. You get 38.25. You do have enough money.
4.) Subtract 100-15, giving you 85. Move decimal over from percent. .85.
Now you would multiply .85 times k. B should be the answer.
They collected 300 cans in all. I did this by multipying 63 by 100 (6300) then divided it by 21. I hope this helps!
C. in^3 because is you describe the amount of something then you are finding out what the volume is.
Answer:
For f(x) = 2x2 + 4x - 6, the answers that go in this ones box is, x-intercept: (1,0)
y-intercept: 0,–6)
For g(x) = -2x2 + 4x + 3, the answers that go in this ones box is, y-intercept
: (0,3)
For h(x) = 2x2 - 4x - 6, the answers that go in this ones box is, x-intercept: (3,0) y-intercept: 0,–6)
