Answer:
nearest tenth is 23.5
nearest hundredth is 23.55
Step-by-step explanation:any number more than 5 is rounded up to +1 for the next number so for tenth 23.546= 23.5 and for hundredth 23.546=23.55
Answer:
f(x) = 488
Step-by-step explanation:
first you plug in 82 in for x then you multiply by 6 times 82 and you get 492 then you subtract 4 and you get 488
Answer:
1. Slope at a=2 is 2.
2. Slope at a=0 is 2.
Step-by-step explanation:
We need to find the slope of y = f(x) at x = a.
1.
The given function is
It can be written as
Differentiate with respect to x.
Substitute x=2 to find the slope of y = f(x) at a=2.
Therefore the slope of function at a=2 is 2.
2.
The given function is
It can be written as
Differentiate with respect to x.
Substitute x=0 to find the slope of y = f(x) at a=0.
Therefore the slope of function at a=0 is 2.
Answer: The radius is 2 inches.
The circumference is approximately
12.56 inches.
Step-by-step explanation:
Given : The diameter of a dartboard = 4 inches
Since , radius is half of the diameter.
Therefore, radius of dartboard = (diameter) ÷ 2
= (4 inches ) ÷ 2 = 2 inches
Also, Formula for circumference : , where r is radius.
Now , Circumference of dartboard =
Hence, The radius is 2 inches.
The circumference is approximately
12.56 inches.
This in what I got:
(-7i)(10i)
-70i
