Answer:
(7,-1)because it is problem of vector lesson so that we have to use formula of vector
1. You are given PR and RS, so simply add the two measurements to get PS.
28.2+30.7= 58.9
2. Subtract QV from QT to get TV.
78-56= 22
3. Again, Subtract QV from QT to get TV.
74-36= 38
4. Similar to question 1, add PR and RS to get PS.
40+53= 93
The pertinent formula is A = P (1 + r/n )^(nt), where
P is the original amount of money (Principal),
A is the compound amount,
r is the annual interest rate, expressed as a decimal fraction,
n is the # of compounding periods per year, and
t is the # of years.
Here, A = $35000 ( 1 + 0.04/4)^(4*6)
= $35000 (1.01)^24
= $35000 (1.2697) = $44440.71
Answer:
10
Step-by-step explanation:
f(x) = 3x + 1
f^-1 = x-1/3 , it is known as inverse function.
f(3)= 3*3 +1
=9+1
=10
To find inverse,
x=3x + 1
y=3x+1
Exchanging the position or x and y
x=3y+1
x-1=3y
.•. y=x-1/3
Answer:
cost of one cupcake = $2.75
cost of one brownie = $1.25
Step-by-step explanation:
Let c = number of cupcakes
Let b = number of brownies
Equation 1: 5c + 2b = 16.25
Equation 2: 7c + 6b = 26.75
Multiply equation 1 by 3:
⇒ 15c + 6b = 48.75
Now subtract equation 2 from this equation to eliminate 6b:
⇒ 8c = 22
Divide both sides by 8:
⇒ c = 2.75
Substitute c = 2.75 into one of the original equations and solve for b:
⇒ 5(2.75) + 2b = 16.25
⇒ 13.75 + 2b = 16.25
⇒ 2b = 2.5
⇒ b = 1.25
Therefore, cost of one cupcake = $2.75 and cost of one brownie = $1.25
