Answer: C) tan(pi/56)
=============================================
Explanation:
I recommend using a trig identity reference sheet. The specific identity we will be using is
What we are given is in the form with A = pi/7 and B = pi/8
A-B = (pi/7)-(pi/8)
A-B = pi(1/7-1/8)
A-B = pi(8/56 - 7/56)
A-B = pi*(1/56)
A-B = pi/56
Therefore,
Answer:
Step-by-step explanation:
- 2396 × 78 + 2396 × 22 =
- 2396 × (78 + 22) =
- 2396 × 100 =
- 239600
Second choice- multiply by 12
Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation (plug in) = =
So your slope is
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept
So the answer is A.
Answer:
inches.
Step-by-step explanation:
The level of a lake was 8 inches below normal.
Now, it is given that the water level decreases inches in June and inches more in July.
Therefore, the new level of water with respect to the normal level will be
= - 8 - 1.25 - 2.375
= - 9.625 inches
= inches. (Answer)
