(I) is not necessarily true. Consider the function f(x) = - |x| on the interval [-1, 1]. There's a maximum at x = 0, but f' (0) does not exist.
But both (II) and (III) are true, so the answer is A.

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the total square centimeters of fabric that Sue must use to cover all faces of the ottoman?
Answers
Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:
[tex]Surface\ Area =2(LB + LH + BH)[/tex]
Where L, B and H are the dimensions.
So,
[tex]Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)[/tex]
[tex]Surface\ Area = 2(378 + 315 + 270)[/tex]
[tex]Surface\ Area = 2(963)[/tex]
[tex]Surface\ Area = 2 * 963[/tex]
[tex]Surface\ Area = 1926cm\²[/tex]
Hence, 1926 cm² of fabrics are needed to cover all surfaces.

4. An isosceles triangle has sides that measure 7cm and 15cm. Find the third side of the
triangle, then find the perimeter.
Answers
Answer:
Third side is 15cm. Perimeter is 37cm.
Step-by-step explanation:
In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.
So if the third side is 7cm
7+7=14cm which is less than 15 cm.
hence third side is 15 cm as
15+15=30cm which is greater than 7cm
15+7=22cm which is greater than 12cm
then
perimeter=15+7+15=37cm

In a circle, what is the ratio of the circumference to its diameter?
area

volume
PI
Answers
Answer:
D. pi
Step-by-step explanation:
Circumference of a circle = [tex] \pi d [/tex]
Diameter = d
Therefore, ratio of circumference of a circle to its diameter would be:
[tex] \pi d : d [/tex]
[tex] = \frac{\pi d}{d} = \pi [/tex] => (d cancels d)
Therefore, the ratio of the circumference of a circle to its diameter is [tex] \pi [/tex]
5% of items in a large batch of items produced at a local foundry' are defective. If 50 of these items are selected at random, what is the probability that exactly 2 of the items will be defective? Round to four decimal places.
Answers
Answer:
0.2611
Step-by-step explanation:
We have x to be binomially distributed random variable which denotes the items number that are defective
We have been given n = 59 as our sample size
Probability of 5% = probability of success
1-5% = 0.95
We solve using this formula
nCxP^xq^n-x
= 50C2(0.05)²(0.95)^50-2
= 0.2611
This is the probability that exactly 2 would be defective
