Answer:

Robyn model makes more sense and Mark's is nonsense

Step-by-step explanation:

In this question ,calculations not required .All we have to do is consider each model logically .

Marks

Marks model shows 20 rather than 2 which means 200 is 10 times as much as 20. It does not make any sense.

Robyn

Robyn model shows 2 which means 200 is 100 times as much as 2 and this is not only correct but also makes sense because 100 *2=200

Amy is just learning how to rock climb. Her instructor takes her to a 26 ft climbing wall for her first time. She climbs up 5 ft
boyakko [2]
Let's compute the speeds as she goes up and down of the climbing wall. Speed is the ratio of distance to time.

Speed going up = 5 ft/(2min * 60 s/1 min) = 1/24 ft/s
Speed going down = 2 ft/10 s = 0.2 ft/s
Net speed = 1/24 ft/s - 0.2 ft/s = 5/24 ft/s

Using this net speed, we can already calculate for the total time:

Speed = Distance/Time
5/24 ft/s = 26 ft/Time
Time = 124.8 seconds or 2.08 minutes

Answer:

The answer is C.

Step-by-step explanation:

The $13 he started off with is the y-intercept or the initial value, which is the point where x=0.

The x-intercept, or rate of change, is $8.50.

The slope intercept formula is y=mx+b, where m=8.5 and b=13.

The equation for this problem is y=8.5x+13.

So the answer is C

3x5 – 7x4 + 6x2 – 14x
Andreas93 [3]

Question is Incomplete; Complete question is given below;

What is the completely factored form of 3x5 – 7x4 + 6x2 – 14x.

Answer:

The Complete factorized form of given equation is x((x^3+2)(3x-7)).

Step-by-step explanation:

Given:

3x^5-7x^4+6x^2-14x

We need to factorize the above equation:

Solution:

On Solving the above equation we get;

Step 1:

First we will take a common factor which is 'x' so the equation will become as;

x(3x^4-7x^3+6x-14)

Step 2:

Now we will Rewrite the above equation so as to factorize the same we get;

x(3x^4+6x-7x^3-14)

Step 3:

Now we take 3x common factor from first 2 terms we get;

x(3x(x^3+2)-7x^3-14)

Step 4:

Now we will take 7 as common factor from last 2 terms we get;

x(3x(x^3+2)-7(x^3+2))

Step 5:

Now we can see the common factor between the 2 terms is x^3+2;

x((3x-7)(x^3+2))

Hence The Complete factorized form of given equation is x((x^3+2)(3x-7)).
