Answer:
the answer is four
Step-by-step explanation:
Because first you do 36/4 which gets you to 9 and then subtract it by 5 to get 4!
Answer:
The answer is C
Step-by-step explanation:
Answer:
Please see attached image and all steps below for both parts
Step-by-step explanation:
Task 1
The following system of equations includes a linear equation and a quadratic one:
it can be solved by using substitution in the second equation of the variable "y" by the linear expression of the first equation:
and this product of two factors will e zero when either factor is zero, that is: when x = 0, or when x = 9 [to make zero the binomial(x - 9)]
There are two solutions: x = 0 and x = 9.
When we graph both expressions in the system, we see that the line intercepts the parabola at the points (0, 2) and (9, 11). See attached image.
Task 2
Part 1:
Let's pick 30 as a number larger than 25. 30 can be written as 40 - 10
So we can use:
to calculate its square.
Part 2:
let's choose a=9 and b=10 so we use:
The amount in the account after the daily deposit for 5 days is $5
<h3>How to determine the amount in the account?</h3>
The given parameters i the question are represented as follows
Initial balance = -$30
Daily deposit = $7
Number of days of deposit = 5
The equation that represents the amount in the account is represented as
Amount = Initial balance + Daily deposit * Number of days
Substitute the known values in the above equation So, we have the following equation
Amount = -30 + 7 * 5
Evaluate
Amount = 5
Hence, the amount is $5

Answer:
approx. 251 in³
Step-by-step explanation:
The appropriate formula to use here is V = πr²h. Substituting 2 in for r and 5 in for h, we get:
V = π(2 in)^2·(5 in), or
V = π(4 in²)(5 in) = 80π in³, or approx. 251 in³
