Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
Answer:
-31
Step-by-step explanation:
since x+5 is a factor then
x=(-5)
f(-5)=-5×3-4×2+3×-5+7
=-15-8-15+7
=-30-1
=-31
Answer:
2⁻⁴
Step-by-step explanation:
0.0625 = 1/16 = 1/2⁴ = 2⁻⁴
City A is 25% less than population of city B. So city A's population is 75% of city B
<h3>
<u>Solution:</u></h3>
Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,
A = 0.75B can be written as,
city A = 75 % of City B
Thus city A's population is 75% of city B
Answer:
3
Step-by-step explanation:
The highest degree amount or exponet amount is the power of a equation.
3 is the highest exponet so it is 3.
