Hi there
First find the future value using the compound interest formula
The formula is
A=p (1+r/k)^kn
A future value?
P present value 1800
R interest rate 0.032
K compounded weekly 52
N time 10 years
A=1,800×(1+0.032÷52)^(52×10)
A=2,478.59
Now find the interest earned
I=A-p
A future value 2478.59
P present value 1800
So
I=2,478.59−1,800
I=678.59
It's b
Good luck!
Answer:
No
Step-by-step explanation:
Use the pythagorian theorm to find whether it's a right triangle or not.
So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared
5.2 squared= 2.4 squared+ 4m5 squared
27.04= 26.01
It's not equal so the triangle isn't a right triangle.
<span>He relationship between rectangular and rotational coordinates can be represented by the vector equation:
r = xi +yj = rcos(theta)i+rsin(theta)j
What values in radians makes
x minimum
y maximum
and x = -y
Ans : x minimum = -r when theta = 180 degrees + any multiple of 360 degrees
y minimum = -r when theta = 270 degrees + any multiple of 360 degrees
x = -y when theta = 135 degrees + any multiple of 180 degrees.</span>
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90
<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120
answer
<CDE = 120°
