To model this situation, we are going to use the standard linear function:
.
1. Since S represent the total amount of money in the savings account,
. We also know that each week she adds $40 to her account, so the slope of our linear equation will be
; therefore,
. Since she started her account with $750,
.
Lets replace those values in our linear function:
We can conclude that equation that models this situation is: 2. Now to find the total amount after 16 weeks, we just need to replace
with 16 in our equation and simplify:
We can conclude that the amount of money in her account after 16 weeks is $1390
Answer:
14400
Step-by-step explanation:
We have 2 groups of 5 elements each
there is a condition all boys will be ahead always, therefore in the group of boys there are
5! = 5*4*3*2*1 = 120 differents form
And the girls at the same time can change theirs places according to
5! = 120
Then total ways for the line up in the conditions of the statement of the problem are
T = 120*120
14400
I think it’s 975 but I don’t know if I’m right
The area of a sector is 339.336 cm²
The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.
It can be determined by using the formula:
Given that;
- Radius r = 18 cm
- Angle θ = 120°
Then. the area of the sector can be calculated as:
A = 339.336 cm²
