Image is missing, so i have attached it.
Answer:
AC = 10sin 40°
Step-by-step explanation:
From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.
Thus, since we want to find AC;
We know that in trigonometric ratios; opposite/hypotenuse = sin θ
In the diagram, θ = 40° and AB = 10
Thus,
AC/10 = sin 40°
Multiply both sides by 10 to get;
AC = 10sin 40°

Answer:
$350
Step-by-step explanation:
This is because in order to pay fees equal to $350 per month when doing haircuts, she would have to do 25 haircuts which equal $350 since 14 x 25 or 14 * 25 is 350.
Substitution:
350 = 14x
/14 /14
25 = x
Answer:
43750 pesos
Step-by-step explanation:
The first thing is to establish the formula in this case as it is a normal distribution is as follows:
z = x - m / sd
where x is the point value, m the mean, sd the standard deviation and z is the z score, we can calculate the z score by means of this 4% and it is found in the normal distribution table.
for 4%. z = 1.75
replacing:
1.75 = (70000 - m) / 15000
m = -1.75 * 15000 + 70000
m = -26250 + 70000
m = 43750
therefore we have that the average is 43750 pesos
Answer:
Step-by-step explanation:
In a static position, the sum of the forces is always 0.
so:
F1 = 480 N
F2 = -600 N
F3 = ?
F1 + F2 + F3 = 0
480 - 600 + F3 = 0
F3 = 120 N (the answer is positive, so the force acts in the same direction as F1)
