Step-by-step explanation: I honestly am too lazy to solve but I will tell you what to do. For number 1-5 you need the amount (a) divided by the Tax/Tip/%off/Discount(d). Whatever that number is (t), you subtract that from a to get the total cost which is (c) So in other words - a-d=t a-t=c UWU
Then onto the next ones. Number 6: First you do 11/2800. Thats the 11%. Next you get 67,530 divide that by that last number you got. Then multiply that by 2800. Then there is your answer
Okay so next one Number 7: Same thing as the other one actually -v-
Next answer mate! Number 8: 3400 x4 + (3400/3.5) x 4= ???? You tell me that ;)
We almost doneeee Number 9: 20460 x 5 + (20460/5.5) x 5= ____ Hhehehehe last one mateyyyy
We actually at the last one. Its been fun helping you! :) Number 10: 35000/7 then whatever that is times 5. I enjoyed going back in my little kid brain tohelp you :)
NB- I used the symbol to represent that the 2 means squared. I hope this helps
A). F(x)=3x^2
F(x)=3(-3)^2
F(x)=3(9)
F(x)=27
B). F(x)=3x^2
F(x)=3(0)^2
F(x)=3(0)
F(x)=0
C). F(x)=3x^2
F(x)=3(2)^2
F(x)=3(4)
F(x)=12
D). F(x)=3x^2
F(x)=3(5)^2
F(x)=3(25)
F(x)=75
Yes I have graphed them and they form a 90 degree angle
Step-by-step explanation:
Given - f(t)=110(1.35)^{\frac{t}{40}}
To find - Write the function in the form f(t)=ae^{kt}. Round all coefficients
to four decimal places.
Proof -
Given that , the function is f(t)=110(1.35)^{\frac{t}{40}}
Now,
We can write it in the form of 
By comparing with the form 
, we get
a = 110.0000
k = 
= 0.0250
