2 tons=4000lbs 3 tons = 6000lbs 4 tons= 8000lbs
The product of two negative integers is positive. (-a) *(-b) = ab True
The product of two integers with different signs is positive. (-a) (b) = -ab False
If two numbers are the same sign, then the product is positive.
a*b = ab -a * -b = ab True
The product of a positive and a negative is negative.
-a * b =- ab a * -b =- ab True
If the signs of two integers are different, then the product is positive.
-a * b =- ab a * -b =- ab False
Answer:
The answer to your question is 39 lb
Step-by-step explanation:
Data
Force = 60 lb
angle = 40°
vertical component = ?
Process
To answer this question, we must imagine a right triangle where the force gave is the hypotenuse, and the vertical component will be the opposite side to the 40° angle.
1.- Look for a trigonometric function that relates the opposite side and the hypotenuse
sin Ф = Opposite side / hypotenuse
- Solve for Opposite side
Opposite side = hypotenuse x sin Ф
- Substitution
Opposite side = 60 x sin 40
- Simplification
Opposite side = 60 x 0.64
- Result
Opposite side = 38.56 ≈ 39 lb
Answer:
Step-by-step explanation:
9^8 to 9^10 involves a change (multiplication) of 9^8 by 9^2 (which is 81).
Over the given interval, f(x) increases by 81.
