Let f(x)=x^2-2x+1

Mathematics
1 answer:
Anarel [89]3 years ago
3 0

Answer:

a.) f'(x) = 2x - 2

b.) horizontal tangent line at (1, 0)

c.) view image

d.) the point given, (-1, -1/2), isn't even located on the graph of f(x). Either there is a typo or the question is poorly stated.

Step-by-step explanation:

a.) You should know how to do derivative already

b.) Horizontal tangent line just mean that the slope is zero. Since a derivative is a slope, just find when the derivative is equal to 0.

c.) The function f(x) looks like a U. The only spot that has a zero slope is at the bottom of the U when the slope changes from negative to positive. Since my horizontal tangent line(where the slope is 0) is located at point (1,0), that must be where the bottom of the graph is,

d.) Poorly stated question. The point given isn't even located on the graph.

the measure of the angle is 88 degrees greater than its complement. what is the measure of the complement?
vazorg [7]
Let the angle be x and it's complement be c.

Then, x = c + 88 and x + c = 90

Substitute the first equation in the second.

(c+88) + c = 90
2c+88 = 90
2c = 2
c =1 

Compliment = 1
Angle = 89

A cable on a crane measures 89 yards 2 feet. How much total cable would be on 14 identical cranes? Convert the answer to larger
babymother [125]

we know that  

1 yard=3 feet

Multiply (89 yards 2 feet) by 14

(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet

convert 28 feet to yards

28 ft=(28/3) yards=9.33 yards

9.33 yards=9 yards+0.33 yards

0.33 yards=1 foot

so

9.33 yards=9 yards+1 foot

substitute

1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255  yards + 1 foot

therefore

<u>the answer is the option</u>

C. 1,255 yards 1 foot
