# Vita has a pice of rope that is 5 meters long. She cuts the rope into pieces that are each 1/3 meter long. How many pieces does she cut?

QUESTION POSTED AT 15/01/2020 - 03:10 AM

Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this:

Multiply by the reciprocal when you are dividing fractions.

### Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º. Scarlett's height is 1.65 meters, so what is the hight of the dam

The height of a dam:
h = x + 1.65 m,
where:
x = 90 m · tan 26°
x = 90 · 0.4877
x = 43.90
h = 43.90 m + 1.65 m = 45.55 m
The height of the dam is 45.5 m.

What is the line-of-sight distance from the television camera to the case of the stadium? Round to the nearest hundred meters.

Looks like sin is best here

sin (7) = opp / hyp
sin (7) = 400 / x
x sin (7) = 400
x = 400 / sin (7)

So we need to get the value of x.

x = 400 / sin (7)
x = 400 / 0.1218
x = 3284.07

Roughly, the correct answer is 3284.1 meters

### Please Help!!! I give a medal to anyone to tries!!! 3 party-goers are in the corner of the ballroom having an intense argument. You walk over to settle the debate. They are discussing a function g(x). You take out your notepad and jot down their statements. • Professor McCoy: She says that 2 is a zero of g(x) because long division with (x + 2) results in a remainder of 0. • Ms. Guerra: She says that 2 is a zero of g(x) because g(2) = 0. • Mr. Romano: He says that 2 is a zero of g(x) because synthetic division with 2 results in a remainder of 0.

Well, the way I see it is that both Mr. Romano, and Ms. Guerra are correct but Professor McCoy is incorrect because he said (x+2) when it should be (x-2).

The factor theorem states that:
If f(a)=0, then (x-a) is a factor

The remainder theorem states that:
If (x-a) is a factor of f(x), then f(x) / (x-a)  = 0

So if 2 is indeed a zero of f(x), then a factor must be (x-2) according to the fist which supports Ms. Guerra and also if (x-2) is indeed a factor as Ms. Guerra says then we know that f(x) / (x-a) = 0 which supports Mr. Romano

Professor McCoy is wrong because he used (x + 2) when it should be (x-2). I know this because according to the factor theorem if f(a)=0, then (x-a) is a factor. And the remainder theorem says if (x-a) is a factor of f(x), then f(x)/x-a =0.

### If a rancher plans to fence a rectangular pasture adjacent to a river. The rancher has 100 meters of fencing, and no fencing is needed along the river. How do you write an area of A as a function of x? Then I would have to find domain afterwards

He perimeter of the area is the length of the fence. Perimeter = x + y + y. This can be simplified to Perimeter = x + 2y. You're told that the rancher has 100 m of fence, so the perimeter is 100 m: 100 = x + 2y (1) The area of a rectangle is given by the formula A = length * width. The length in this case is x, and the width is y. So, A = xy. Solve equation (1) for y. Once you find the expression to which y equals, plug that for y into A = xy. 100 = x + 2y. Solve for y by subtracting both sides by x: 100 - x = 2y. Divide both sides by 2: (100 - x)/2 = y Substitute (100 - x)/2 for y into A = xy: A = x[(100 - x)/2] A = [x(100 - x)]/2 You can rewrite this as (100x - x²)/2 or 50x - (x²/2) or 50x - (1/2x²).

### Which is a shrink of an exponential growth function? a. f(x) = 1/3(3)^x b. f(x) = 3(3)^x c. f(x) = 1/3(1/3)^x d. f(x) = 3(1/3)^x

Explanation:

A shrink of a function is a shrink on the vertical direction. It means that for a certain value of x, the new function will have a lower value, in the intervals where the function is positive, or a higher value, in those intervals where the function is negative. This is, the image of the new function is shortened in the vertical direction.

That is the reason behind the rule:

• given f(x), the graph of the function a×f(x), when a > 1, represents a vertical stretch of f(x),
• given f(x), the graph of the function a×f(x), when a < 1, represents a vertical shrink of f(x).

So, we just must apply the rule: to find a shrink of an exponential growth function, multiply the original function by a scale factor less than 1.

Since it is a shrink of an exponential growth function, the base must be greater than 1. Among the options, the functions that meet that conditon are a and b:

Now, following the rule it is the function with the fraction (1/3) in front of the exponential part which represents a shrink of an exponential function.
