The 4 arrows above the number line represents the distance between 2 and -2 which is 4!
Answer: t= 3/2
Step-by-step explanation: 5/ 7 1/2 = 3/2
Answer:
Option 3
Step-by-step explanation:
We want to work out the surface-area
This is a cylinder and the formula for the surface area of a cylinder is :
2πrh+2πr^2
^ means to the power of
The radius is 15
The length is 18
2(3.14)(15)(18) + 2(3.14){15}^2
Part 1:
(6.28)(15)(18)
(6.28)(270)
1695.6
Part 2:
First, we do the exponents,
15^2 = 225
(6.28)(225)
1413
Part 3:
1695.6 + 1413 = 3108.6
Answer: 3108.6
Hope this helps :)
A) The domain remains the same.
Since, in y = - 2 f(x) , the y is whats being multiplied and therefore changed, not the x or domain.
Therefore D[-6,10] <span>
The range is what changes by a factor of -2.
If the original range was [-8,12], then the new one is
[(-8 x -2),(12 x -2)] = [16 , -24].
However, you must flip the numbers to make the interval true, giving you R [-24,16]</span>
