Answer:
f(-4)=-2(-4)²+8(-4)-10=-2×16-32-10=-74
Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%
Hope it helps:-)
This is a rombus hope this helps!
Answer:
48
Step-by-step explanation:
Since it's a right angle, it's automadically 90 degrees so you just have to add 23+ 19 and subtract from 90.
23 + 19 = 42
90 - 42 = 48
