Answer:
Step-by-step explanation:
Since we are talking about compounded annual interest, we can use the Exponential Growth Formula to calculate the answer for this question.
Where:
- y is the total amount after a given time
- a is the initial amount
- r is the interest rate in decimal form
- t is the amount of time
First we need to calculate the total after 2 years with a 9% interest.
So after 2 years there will be £1,188.10 in the account. Now we can add £3000 to that and use the new value as the initial amount, and calculate the new total in 5 years.
So now we can subtract the £4000 purchase from the amount currently in the account, and calculate one more year of interest with the new initial amount.
So at the end you would have £2,662.86 in the account one year after the purchase.
1/2×12m×18.2m=109.2m2
109.2m2÷21.8m÷1/2=10m(nearest whole number)
h=10m
Put the value where the variable is and do the arithmetic.
f(-4) = -5(-4) +(-4)/(-2)
= 20 + 2
= 22
The appropriate choice is
C. 22
The formula for the area of a triangle is A = 1/2 x b x height. But, we don't have the height here. To find the height, we can use the Pythagorean theorem.
With Pythagorean theorem, we'll be finding one of the legs. If we split the original triangle in 1/2 from the vertex to the base, we now have two right triangles. Both of these right triangles have a 30 cm hypotenuse and one 13 cm leg (remember we divided the entire original triangle in half).
30^2 = 13^2 + b^2
169 + b^2 = 900
b^2 = 731
b =
Now that we know the height of the triangle, we can find the area.
A = 1/2 x 26 x
A = 13 x
A = 351.48
The final area, rounded to the nearest whole number is 351 centimeters squared.
Note: Please know that depending on if the answer rounded before using it to find the area, the final answer may then be rounded to 352.
Hope this helps! :)
Answer:
- 7/8
Step-by-step explanation:
m = Δy/Δx = (10-3)/(2-10) = - 7/8
