Answer:
495
Step-by-step explanation:
expressing 99 as 90 + 9 , then
5 × 99
= 5(90 + 9) ← multiply each term in parenthesis by 5
= 450 + 45
= 495
The answer is decreased. the statement "the temperature decreased by 7 degrees indicates that a negative interger should be used

Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function (
) times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function:
, and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
