Answer:
about 8.3 miles an hour.
Step-by-step explanation:
34/4 is 8.5
90/11 is 8.2
average: 8.3
From the given the function, <span>y(t)=−t²+14t−40; the graph will be as shown below:
From the graph, it is evident that between the intervals 6</span>≤t≤8<span>:
The value of our function decreases over the given interval. Hence the answer is:
</span><span>a. The value of y(t) increases over the interval 6≤t≤7
</span>
Hello there!
See the attachment bellow for the answer.
Let me know if you have any questions about the answer~!
Answer:
3 and 7 respectively
Step-by-step explanation:
Let the mass, in milligrams, of vitamin C in an apple be x
Let the mass, in milligrams, of vitamin C in a pear is be y
x+2y=17
2x+y=13
Solving for x and y, we get x=3 and y=7
Answer:
Step-by-step explanation:
The given function is,

The parent function of it is,

In
graph y-axis is an asymptote (vertical) , so never crosses the y-axis. Hence no y intercept. And x intercept of
is x=1.
The sign of x is changed in the given function
as compared to its parent function 
While reflecting over y axis or x=0 line, only the sign of x changes.
So graph of
is the reflection of
over y axis. Hence it has no y intercepts, x intercept at x= -1 and y-axis as asymptote (vertical).
