Using the I=PRT formula, you can plug in some things we already know.
We know the principal, which is 43,200, we know the interest rate per year, and we finally know how much time he is going to have his money in there. But, he wants 4 months, and 4 months is 1/3 of the whole year, so we are going to use that to plug it in our formula. Now, we have
This equals to 2016.
But this is not our final answer. 2016 is just the amount of money he earned in those 4 months, not his whole savings, so we add 2016 to 43200 to get 45216
Answer:
5:1 is the unit rate hoping I am right
Area of a rectangle is length times width:
3 to the (2 over 3) power is ∛3²
A=∛81*∛3²
A=3∛3 * ∛3²=3∛3³=3*3=9

Step-by-step explanation:
First exercise:
We have a right triangle with the values of each side an we have to find the following trigonometic functions (taking into account the secant function is the inverse of the cosine, the cosecant is the inverse of the sine):
1)
2)
Then:
3)
Then:
4)
Then:
Second exercise:
5) Here, we are given another right triangle and we have to find the measure of the angle .
So, according to the figure, we can use the tangent function:
Finding the value of :
Answer:
The side length of the large square is √2 times larger than the side length of the small square.
Step-by-step explanation:
Suppose we have a small square (square 1) and a large square (square 2). The area of the large square is twice that of the small square, that is,
A₂ = 2 A₁
A₂/A₁ = 2 [1]
The area of a square is equal to the length of the side (l) raised to the second power.
A = l²
l = √A
The ratio of l₂ to l₁ is:
l₂/l₁ = √A₂ / √A₁ = √(A₂/A₁)
We can replace [1] in the previous expression.
l₂/l₁ = √2
The side length of the large square is √2 times larger than the side length of the small square.
