Simplify:

2(n-4)

Answer:
2(n-4) = 2n - 8 .........distributive property

Answer:
the answer is 2n - 8

you are distributing 2 into n and 4 so 2 times n is 2n and 2 times 4 is 8

you are distributing 2 into n and 4 so 2 times n is 2n and 2 times 4 is 8

What is the slope of the line passing through the given points.(-3,2), (6,-1)

Are the arcs below congruent?B120°G1139не004A. No, because the arcs do not have the same measure.B. There is not enough information to determine.C. Yes, because the central angles are the same.D. Yes, because they are both minor arcs.By

What’s the correct answer for this question?

I need help on this, all I need to know is how to find the missing angle, no answer just the equation. Thank you!

Suppose a parallelogram has sides of length a and b. Is this enough information to compute the area of the parallelogram? If not, what additional information is required?

**Answer:**

the answer is, Y= -27/64

Answer:it’s actually very simple it’s A.

Step-by-step explanation: anything that is below one is negative that’s how I got my answer.

**Answer:the answer is A**

**Step-by-step explanation:i did the test**

The correct set of **hypotheses **for the **sample** in July is H0: μ ≠ 80 Ha: μ = 80.

The** null hypothesis** H0 which is also known as the default hypothesis states that there is no relationship between the population parameters. The **alternative hypothesis** (H1 ) states that there is a relationship between the population parameters.

To learn more about the **null hypothesis,** please check: brainly.com/question/4454077

Answer:

u <= 80

u > 80

Step-by-step explanation:

The happiest would be

Null hypothesis: u <= 80

Alternative hypothesis: u > 80

b. hyperbolic paraboloid

c circular paraboloid

d.circular cylinder

e. elliptic cylinder

Following are the calculation to the given equation:

Given **vector equation:**

The corresponding parametric equations for the given surface is given by,

For any point (x,y,z) we have that,

So, after eliminating the parameters, we get,

Therefore, the answer is** "Option c".**

**Learn more:**

The surface represented by the given **vector equation** r(s, t) = s sin 4t, s2, s cos 4t is a circular cylinder. This can be inferred from the structure of the equation and the characteristics of the represented shapes.

The surface represented by the given vector equation,

**r(s, t) = s sin 4t, s2, s cos 4t**

, is a type of cylindrical surface due to the structure of the equation. This can be identified by the s terms being tied to sin/cos functions and an independent s^2 term. This shows that the s variable is acting as a 'driver' of the shape, while t coordinates the rotation. Owing to the periodic sin and cos functions in the vector equation, the surface does not lie in a single plane, ruling out the option of a plane. It also does not exhibit features of a paraboloid or hyperbolic paraboloid. Hence, it's shown that the vector equation represents a

circular cylinder

**Answer:**

The length of material is 68.7 yards.

**Step-by-step explanation:**

If the material is delivered in a roll, we can calculate how many material is delivered by turn (one rotation). In one turn it delivers (π*D) of material, its perimeter.

If the diameter is 46 mm, in one turn the material delivered is

As we know the rotational speed, we can calculate the amount of material delivered by unit of time:

If the roll turns for 90 seconds (or 1.5 min) we can calculate

As we need the result in yards, we can convert (1 yard=914.4 mm)
