Answer:
c=13 and a=20
Step-by-step explanation:
Here you need to use the Pythagoras theorem :
c²=a² + b²
c = √a² + b²
c = √(12)²+(5)²
c= √144+25
c = √169
c = 13
2) c²=a²+b²
b= √c²-b²
b= √(29)²-(21)²
b = √400
b = 20
In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation
Answer:
f(- 5) = 13
Step-by-step explanation:
Substitute x = - 5 into f(x)
f(x) = - 3x - 2 , then
f(- 5) = - 3(- 5) - 2 = 15 - 2 = 13
66
Difference means subtract. So, 101-35=66
Answer:

Step-by-step explanation:
we have

Solve the quadratic equation to find the zero's or x-intercepts
Remember that
The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
the solution is 
Using the formula for simple interest, it is found that he paid $119.87 in interest.
The<u> simple interest formula</u> is given by:
- E is the amount of interest earned.
- P is the principal(the amount of money invested).
- I is the interest rate(yearly, as a decimal).
- t is the time, in years.
In this problem:
- Borrowed $2,700, thus

- Interest rate of 3.5%, thus

- From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is

Thus, the interest paid was of:

$119.87.
