Answer:
the same number of teachers as students were surveyed...im not exactly sure
Step-by-step explanation:
(100/70)*56 = 80
56 is 70 percent of 80
<h3>
Answer: g = -2</h3>
======================================================
Explanation:
We will use the slope formula
m = (y2-y1)/(x2-x1)
Plugging in the given items leads to
-5 = (g-8)/(6-4)
Now solve for g
-5 = (g-8)/(6-4)
-5 = (g-8)/2
-5*2 = g-8
-10 = g-8
-10+8 = g
-2 = g
g = -2
We have (6,g) turn into (6,-2)
The two points (4,8) and (6,-2) are on a line of slope -5.
-------------------
As a way to check, we'll find the slope of the line through (4,8) and (6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-8)/(6-4)
m = -10/2
m = -5
The answer is confirmed.
F(x) = -4(-1) - 5
f(x) = 5 - 5
= 0
Good luck! :)
Answer:
- 5 min: 3,029,058
- 10 min: 3,398,220
- 60 min: 10,732,234
Step-by-step explanation:
The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).
