Answer:
x = -2
Step-by-step explanation:
Line q is the horizontal line y = 6, so the perpendicular line will be vertical. In order for it to go through the point (-2, 3), the equation must be ...
x = -2
Answer:
41.5 N
Step-by-step explanation:
Torque is given by:
τ = rF
Solved for force:
F = τ / r
The value of r is the distance from the end of the wrench to the center of the lid, which is:
r = (0.089m / 2) + 0.17m
= 0.2145m
Therefore:
F = 8.9N∙m / 0.2145m
= 41.5N
Answer:a=4
Step-by-step explanation:
-4+4a=12
Add 4 to both sides
4a=16
Divide both sides by 4
a=4
Therefore a=4
Answer:
(0,5)
Step-by-step explanation:
If you plug in 0 in all the variables of x, f(x)=0+0+5
We know that f(x) is y...so y=5, while x=0
Answer:
examine the next digit and increase the number accordingly, before dropping the digits of no interest.
Step-by-step explanation:
You round any number by looking at the digit in the place to the right of the one you want to round to. If it is 5 or more, you add 1 to the number in the place you're rounding to, and drop (or zero) all digits to the right of that.
If you want to round this to tenths, you observe that the hundredths digit is 7, which is more than 4. So you add 1 tenth and drop the hundredths digit:
99.87 ≈ 99.9 . . . . rounded to tenths
If you want to round this to units, you observe that the tenths digit is 8, which is more than 4. So you add 1 unit and drop the tenths and hundredths digits.
99.86 ≈ 100 . . . . . rounded to nearest integer
