Answer:
Original Value= $361.21
Step-by-step explanation:
Giving the following information:
The value of the savings bond increases by 3% each year. One year after it was purchased, the value of the savings bond was $515.
<u>To calculate the original value of the bond, we need to use the following formula:</u>
OV= PV/(1+i)^n
OV= original value
PV= present value
i= increase rate
n= number of months
OV= 515 / (1,03^12)
OV= $361.21
Answer:
Part A: 64 (right-side 3th cell) and 7 (left-side 4th cell)
Part B: 5 hours- $45; 6 hours- $54; 8 hours- $72
Part C: $5 more
Step-by-step explanation:
Explanation for Part C- We know that if she works 5 hours mowing lawns, she will earn $40. But, when she works at the theme park we use the ratio given to find out how much she earn per hour. In her case she earns $9 for every hour she works at the theme park. now if you multiply that by 5 we can find out how much she earns in 5 hours which is $45. This is $5 more than what she earns mowing lawns for the same amount of time. Here we can conclude that Barbara earns $5 dollars more working at the theme park for 5 hours rather that mowing lawns.
If you can please name me the brainliest that would be much appreciated. Thanks and Good Luck!
The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.
I am going to assume that the equation was supposed to be
Answer:
It is a polynomial. It is a binomial and it has a degree of 5.
Step-by-step explanation:
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables so will be considered a polynomial.
A binomial is a polynomial with 2 terms.
The degree of a polynomial is the highest exponent in it which in this equation is 5.
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
