Answer:
<u>x = 6.4</u>
Step-by-step explanation:
Taking the sin ratio of the angle :
- sin 40° = x / 10
- 0.64 = x / 10
- x = 0.64 × 10
- <u>x = 6.4</u>

Answer:
The answer to your question is: f(0) = 7.07 units
Step-by-step explanation:
f(x) = 2(x)² +5√(x + 2) function
f(0) = 2(0)² +5√(0 + 2) substitution
f(0) = 0 + 5√2 simplify
f(0) = 5√2
f(0) = 7.07 units
Answer:
y = -8
Step-by-step explanation:
y = -10 - x
y = -10 - (-2)
y = -10 + 2
y = -8
Answer:a=-8
Step-by-step explanation:
4+7a=12+8a
So first you want to have the variables on the same side
4+7a-7a=12+8a-7a
This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes
4=12+a
Now there are two ways of doing this.
1. 4-12=12-12+a
You moved the 12 to the left side so you have the same variable on one side
4-12=-8
So then a=-8
Or
2. 4-4=12-4+a
0=8+a
then you would have to subtract 8 to keep 'a' by itself
-8=8-8+a
simplify it
-8=a
