The <em>correct answer</em> is:
400,000.
Explanation:
The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.
The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.

Answer:
45°
Step-by-step explanation:
size of each angle = 360°÷8
8 are the number of sides
you get 45°
Answer:
a=1
Step-by-step explanation:
Because x-1 is factor of f(x)
for x1=1, f(1)=0, then
f(1)=5*1^3+a*1^2-4*1-2=0
5*1+a*1-4-2=0
5+a-6=0
a-1=0
a=1
Answer:
f^-1(-32)=6
Step-by-step explanation:
<u>Find the inverse of the function f(x)=4-6x:</u>
f(x)=4-6x
y=4-6x
x=4-6y
x-4=-6y
(x-4)/-6=y
-1/6x+2/3=y
y=-1/6x+2/3
f^-1(x)=-1/6x+2/3
<u>Plug in f^-1(-32) for f^-1(x) and simplify:</u>
f^-1(-32)=-1/6(-32)+2/3
f^-1(-32)=16/3+2/3
f^-1(-32)=18/3
f^-1(-32)=6
