Answer:
- V(t) = 25(1.07^t)
- V(t) = 40(1.05^t)
Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
<u>Coin A</u>
P = 25, r = .07
V(t) = 25(1.07^t)
<u>Coin B</u>
P = 40, r = 0.05
V(t) = 40(1.05^t)
You would have to count the faces of cubes after you’ve joined them and then add all the surface areas up of each individual cube . I drew a pic to help you
Answer:
Slope: -4
Y-intercept: 5
Step-by-step explanation:
The slope goes down 4 and over one which means that the slope is -4.
When X is 0, Y is 5
Good Luck!!
Answer:
y = -6x + 30
Step-by-step explanation:
The inicial value you have is $30, so this will be the value of y after 0 weeks, that is, x = 0
After one week, you spend $6, so you will have y = 30 - 6 = 24 when x = 1.
With these pair of values, we can find the linear equation:
y = ax + b
for x = 0, y = 30:
30 = a*0 + b
b = 30
for x = 1, y = 24:
24 = a*1 + 30
a = 24 - 30 = -6
So, our equation is:
y = -6x + 30
Answer:
37.5%
Step-by-step explanation:
you have 8 slices that should represent 100% so 100 divide 8 is 12.5
12.5 multiply by the three red sections you have then you get 37.5%
