Answer:
AC = 18
Step-by-step explanation:
Given the question:
<em>In a right triangle, m∠A = 30° and AB = 12√3 (AB is the hypotenuse). How long is AC?</em>
Side AC is adjacent to angle A. Then, by definition of cosine:
cos(A) = adjacent/hypotenuse
cos(A) = AC/AB
AC = cos(A)*AB
AC = cos(30°)*12√3
AC = 18
If you would like to know how many dollars is the increase, you can calculate this using the following steps:
7% of $45 = 7% * 45 = 7/100 * 45 = $3.15
Result: The increase is $3.15.
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
For this case we have the following equation:
a = v ^ 2 / r
From here, we must clear the value of speed.
We have then:
v ^ 2 = a * r
v = root (a * r)
Answer:
the formula for the velocity is:
v = root (a * r)
Answer:
A: radius of the sphere
Step-by-step explanation:
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
