Answer:
Step-by-step explanation:
Using the formula for the growth of investment:
.....[1]
where,
A is the amount after t year
P is the Principal
r is the growth rate in decimal
As per the statement:
Scott invests $1000 at a bank that offers 6% compounded annually.
⇒P = $1000 and r = 6% = 0.06
substitute these in [1] we get;
⇒
Therefore, an equation to model the growth of the investment is,
Answer:
CI=P*(1 + R/100)^18
A=(CI + P) = P(1+R/100)^18
13500/P=1(100+R/100)^18
A/P=(100+R/100)^18
A/P=(100+R/100)^18
A=13500$ as (750 * 18)
(13500)/P=(1 +1.15/100)18
(13500)/P=(1+1.15/100)18
13500=((1.0115)^18
P=R$10989.02
Step-by-step explanation:
CI=Compound Interest
A=Amount
P=Principal.
Answer:168
Step-by-step explanation: First you do 82 times 3.75 which is 307.50. Then you do 2071.5 - 307.5 = 1764 Then you do 1764 divided by 10.50 which is 168
Answer:
2) x times the seventh root of x cubed
Step-by-step explanation:
![\displaystyle\sqrt[7]{x^5}\cdot\sqrt[7]{x^5}=\sqrt[7]{x^{5+5}}\\\\=\sqrt[7]{x^{7+3}}=\sqrt[7]{x^7}\cdot\sqrt[7]{x^3}\\\\=x\sqrt[7]{x^3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5B7%5D%7Bx%5E5%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E5%7D%3D%5Csqrt%5B7%5D%7Bx%5E%7B5%2B5%7D%7D%5C%5C%5C%5C%3D%5Csqrt%5B7%5D%7Bx%5E%7B7%2B3%7D%7D%3D%5Csqrt%5B7%5D%7Bx%5E7%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E3%7D%5C%5C%5C%5C%3Dx%5Csqrt%5B7%5D%7Bx%5E3%7D)
Answer:
5
Step-by-step explanation:
Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.
Let x be the number of questions, solving by trial and error:

Therefore, the minimum number of questions in the game is 5.
