C:-3=<x<13

D:-3<x=<13

Step-by-step explanation:

Ok, first lets do A

-3 and -13 and the endpoints and the dots are hollow so its not including

therefore the answer is -3<x<13

next, B

same endpoint this time but both dots are filled in so they are included

therefore: -3=<x=<13

(I'm typing on a keyboard!!! i can't do the fancy symbols lol)

C

same endpoints again but -3 is black and 13 is not

so: -3=<x<13

D

I think you have got the hang of it now probaly

-3 is not filled and 13 is

answer is -3<x=<13

A frustum of height 4 is part of a larger pyramid of height 6. What is the ratio of the volume of the frustum to the volume of the pyramid?

Answers

Answer:

26 : 27

Step-by-step explanation:

The volume of the pyramid with height of 6:

V = 1/3bh = 1/3b*6 = 2b,b is area of the base

The volume of the smaller pyramid is:

V₁ = 1/3*b₁h₁

We know:

h₁ = 6 - 4 = 2h₁/h = 2/6 = 1/3

The base sides have same ratio as similar triangles.

b₁ = (1/3)²b= b/9

The volume of smaller pyramid:

V₁ = 1/3*2*b/9 = 2b/27

The difference of the volumes is the volume of the frustum:

V₂ = V - V₁V₂ = 2b - 2b/27 = 52b/27

The ratio of V₂ to V is:

52b/27 ÷ 2b = 26/27

For what value of m is the expression x4+mx2+64 a perfect square?

Answers

Answer:

x^4 + 1/4 x^2 + 1/64 is a perfect square. 16x^4 + 4x^2 + 1/4 is a perfect square. (4x^2 + 1/2)^2. So you must add -3/4

Step-by-step explanation:

The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.

What is a perfect square trinomial?

A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.

The equation is given below.

⇒ x⁴ + mx² + 64

Then the value of a, b, and c will be 1, m, and 64, respectively. Then the equation will be given as,

b² = 4ac

m² = 4 x 1 x 64

m² = 265

m² = 16²

m = 16

The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.

work out m and c for the line y= 2x+1​

Answers

Answer:

m = 2, c = 1

Explanation: In the y = mx + b (or y = mx + c) format, the m is the slope of the line and the c/b is the y-intercept, or where the line crosses the y-axis. If we substitute the information from the given equation, y = 2x + 1, into the general formula, we know that the m is 2 and c is 1.

The total cost of an electronic photo
display comes to $100. The price
y plus the tax of $6 equals $100.
Write an equation to find the price
of the electronic photo display.

Answers

Answer:

P = y * 1.06

Step-by-step explanation:

Let y be the net price (no tax), t the tax (as a factor) and P the total price (tax included),

P = y * t

From the info provided, we know that for each 100 USD, 6 USD is tax, so 6%,

TIP: By multiplying by 1.06 we add the 6% to the net price (6% is 0.06)

P = y * 1.06

What are the solutions of x squared + 6 x minus 6 = 10?

Answers

Answer:

X = -8 and X = 2

Step-by-step explanation:

X^2 + 6X - 6 = 10

Bring the 10 over:

X^2 + 6x - 16 = 0

From here, either use the quadratic formula or

manual factorization by finding its roots:

Manually:

(X + 8)(X - 2) = 0

Equate each factor to 0 you will get:

X + 8 = 0  and X - 2 = 0

Solutions are -8 and 2 respectively.

The answer is X= -8 and x= 2
