Hello there! Given the equation, we can solve through a series of steps:
1. Convert
In this step, we convert the mixed numbers to make them improper:
2 x 4 + 1 = 9, which means -4 1/2 = -9/2
4 x 3 + 3 = 15, which means -3 3/4 = -15/4
2. Multiply
Now that we have the improper fractions, we can multiply accordingly:
(-9/2 • -15/4) = -135/8
3. Simplify
Since we have our result, we can simplify to a mixed number:
-135/8 = 16 7/8
Your final answer is 16 7/8. Hope this helps!
Answer:
D
Step-by-step explanation:
An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.
Consider expression D
This will be undefined when
x + 5 = 0 ⇒ x = - 5 ← excluded value → D
Answer:
49.69
Step-by-step explanation:
use Equation for cos15°
cos15°=48y/distance
0.9659=48/Distance
distance=48/0.96592
distance=49.69 yard
A cardboard box rests on the floor of an elevator. The box has a mass m = 3.75 kg and the elevator has an upward acceleration of a
Part a. Select the Free Body Diagram for the system
Part b. Write an expression for the sum of the forces actinv on the box in the y direcion, given that up is the positive y direction. Your answer should be in terms of FN, m, g.
Part c. Write an expression for the normal force FN, that the block experiences in terms of the elevator's accelaration, the block's mass and the accelaration of gravity
Part d. If the elevator's accelaration has a magnitude of g in the downward direction, what would the normal force FN1 be in Newtons? (Numerical value)
Part e. If the elevator's accelaration had a magnitude of g in the upward direction, what would the normal force FN2 ve in Newtons? (Numerical value)
