Answer:
a. The critcal points are at

b. Then,
is a maximum and
is a minimum
c. The absolute minimum is at
and the absolute maximum is at 
Step-by-step explanation:
(a)
Remember that you need to find the points where

Therefore you have to solve this equation.

From that equation you can factor out
and you would get

And from that you would have
, so
.
And you would also have
.
You can factor that equation as 
Therefore
.
So the critcal points are at

b.
Remember that a function has a maximum at a critical point if the second derivative at that point is negative. Since

Then,
is a maximum and
is a minimum
c.
The absolute minimum is at
and the absolute maximum is at 
sara speed is half of Jeanette's so if jeanette ran 7 miles then her walking speed is 3.5MPH and sense she is 7 miles ahed sara is 10.5 miles behind... 3.5MPH which is jeanette speed is double than sara so 3.5/2 is 1.75MPH... Saras walking speed is 1.75MPH
Answer: 3.75 liters
Step-by-step explanation:
Zoe uses 250 milliliters of milk to make a loaf of bread.
If she needed to make 15 loaves therefore, she would do the following:
= 250 * 15 loaves
= 3,750 milliliters of milk
Then convert the above quantity to liters.
1 Liter = 1,000 milliliters.
3,750 milliters to liters is:
= 3,750 / 1,000
= 3.75 liters
To find the value of x , bring the variable to the left side and bring all the remaining values to the right side. simplify the values to find the result.

See the attached figure. The smaller the θ angle, the smaller the AB side will be. If the angle θ = 90º, then AB = 25. As θ < 90, then AB < 25
5X - 10 < 25
5X < 25 + 10
X < 35/5
X < 7
The AB side can be neither zero nor negative. So
5X - 10 > 0
5X > 10
X > 10/5
X > 2
<h3>2 < X < 7</h3>
