1. How many positive integers have a value between the square root of 8 and the square root of 72?2. what is the 65th odd number ?
a. 125
b. 133
c. 131
d. 127

Answers

Answer 1
Answer: 1. sqrt 8 = 2.8
sqrt 72 = 8.5
There are 6 positive integers between these numbers (3 to 8).

2. So the 65th odd number is 2 * 65 – 1 = 129.

2. Name the three-dimensional figure shown in the picture. (1 point)O triangular prism
O square prism
O square pyramid
O cone

Answers

The solution is Option C.

The figure represents a square pyramid

What is the surface area of the pyramid?

The total surface area is the summation of the areas of the base and the three other sides. A = B + ( 1/2 ) ( P x h ), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid

Surface Area of Pyramid = B + ( 1/2 ) ( P x h )

Volume of Pyramid = ( 1/3 )a²H

where B is the area of the base of the pyramid, and h is its height.

Given data ,

Let the figure be represented as A

Now , the figure A is not a triangular prism as the base of the prism is not a triangle

And , the figure A is not a square prism as the top of the prism is not a square

Furthermore , the figure A is a square pyramid as the base of the pyramid is a square

And , it is not a cone because the base is not circular in shape

Hence , the figure is a square pyramid

Where is the picture???

Suppose an investor builds a stock portfolio with a variety of shares in various high tech companies. The value of the stock portfolio is modeled by the function y = 2x^2 - 20x + 100, where y is the value of the portfolio in hundreds of dollars, and x is the time in months. a) Find the x-coordinate of the vertex. Show all work leading to your answer and write the answer in simplest form.

b) Find the y-coordinate of the vertex. Show all work leading to your answer and write the answer in simplest form.

c) What does the vertex represent for this situation? Write 1 - 2 sentences to explain your answer.

Answers

Answer:

Step-by-step explanation:

We can find the vertex either by completing the square or taking advantage of the simple formula x = -b / (2a), which provides the x-coordinate of the vertex.

Here a = 2, b = -20 and c = 100.  Then the x-coordinate of the vertex is at

x = -(-20) / (2*2), or x = 5.

Next, evaluate y = 2x^2 - 20x + 100 to find the y-coordinate of the vertex.  It is y(5) = 2(5^2) - 20(5) + 100, or y(5) = 50 - 100 + 100, or 50.  y = 50.

The vertex is at (5, 50).  This states that the stock reaches its minimum value, $50 per share), after 5 months.  From that time on, the stock appreciates (increases) in value.

What is 95% of 35?
A.52.25
B.33.25
C.19
D.38

Answers

The answer is B (33.25)

Finding the answer is very easy. You first need to divide 95% by 100 to get .95. Then, multiply .95 by 35 to get 33.25.

A pentagonal-based prism is sliced horizontally by a plane parallel to the base. Which figure best represents the shape of a cross-section parallel to the slice?

Answers

Since a pentagonal based prism is sliced horizontally by a plane parallel to the base. So the figure must be similar to the base of the prism because it was sliced parallel to base. Since it is a pentagonal based prism, then the cross section is also pentagon in shape
