Answer:
3
Step-by-step explanation:
Because you just have to replace and what would it give = 8(3) -(-5) = 29
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
Answer:
Step-by-step explanation:
A. (b - 10)(b + 10) = 180
-100 = 180
= 280
b = 
b = 2
Your A is correct.
B. 2
- 10 = c
c = 6.733200531 = 6.73 Try rounding to 3 significant figures.
C. 2
+ 10 = d
d = 26.73320053 = 26.7
You are correct in all 3 answers. Perhaps you should try rounding to 3 significant figures for your c and d values.
I hope this helps!! ^-^
Answer:
p=0.125
Step-by-step explanation:
2p+6p=1
Add like terms
8p=1
Divide both sides by 8 to get p by itself
8p/8=1/8
p=0.125
