Answer:
510.10
Step-by-step explanation:
Notice the common ratio 0.09, which is also the projected annual growth rate.
In 2008, 8 years after 2000, the company's net worth should be
w(8) = 256(1.09)^8 = 510.10
A)The total cost would be: x=15a+12b+18c where x is the total cost and a,b,and c are the amount of stocks you bought from their respective companies.
B) Since you bought 10 A stocks, you must have bought 20 C stocks. That adds up to 30 bought, leaving 15 for B.
x=(15)(10)+(12)(15)+(18)(20)
x=150+180+360=$690 spent
C) A's stock is now 15(1.25) which is 18.75. C's stock is now 18(.90) which is 16.2
new equation is 18.75a+12b+16.2c=x
D) Substitute the number of stocks we bought from each in again:
187.5+180+324=$691.5
The cost went up slightly, so divide 690/691.5 then multiply that number by one hundred. You get that you spent in B 99.8% the amount you spent in C. So 100-99.8= an increase of <u>.2% </u>
Answer:
B
Step-by-step explanation:
A number increased by 7 means, 7 was added to the number and the result is 15
Answer:
x+5y+5=0
Step-by-step explanation:
y=5x+6
Therefore the gradient of the line = 5
Now reciprocate the gradient and negate it
i.e -1/5
let (x,y) and (-15,2) be points on the line
y-2/x-(-15)=-⅕
5y-10=-x-15
5y-10+15+x=0
x+5y+5=0
Therefore the equation of the line =
x+5y+5=0
Answer:
A. 3n³
Step-by-step explanation:
base (b) = 3n²
height (h) = 2n
Area of triangle
= 1/2 * b * h
= 1/2 * 3n² * 2n
= 3n³
