A=s^2
da/dt=2sds/dt
we know each side increases at 5cm/s
da/dt=2s(5cm/s)
note, when a=25cm2, s=5cm
so da/dt=2(5cm)(5cm/s)=[50cm2/s]

In class, Julie was asked to create a scenario for the linear function shown. She came up with the following: .Joe planned a hik
Law Incorporation [45]

Answer:

1. Julie’s scenario doesn't match the linear function graphed, because the graphed function is f(x)=-3x+12 and must be f(x)=-5x+12

2. She has counted the slope of the line incorrect.

3. She can write f(x)=-5x+12 and draw the line with the x-intercept will be at (2.4,0) and y-intercpt ar (0,12).

Step-by-step explanation:

If Joe parked 12 miles away from the cabin and after one hour, he was still 7 miles from the cabin, then he had walked 12 - 7 = 5 miles per hour.

The initial positon of Joe is at point (0,12) (after 0 hours passed, Joe was 12 miles from the cabin). The line must pas through the point (1,7) ( after one hour, he was still 7 miles from the cabin ).

Find the slope:

\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{7-12}{1-0}=-5

So, the slope of the linear function should be -5 (not -3).

Then the equation of the function is

f(x)=-5x+12

1. Julie’s scenario doesn't match the linear function graphed, because the graphed function is f(x)=-3x+12 and must be f(x)=-5x+12

2. She has counted the slope of the line incorrect.

3. She can write f(x)=-5x+12 and draw the line with the x-intercept will be at (2.4,0) and y-intercpt ar (0,12).

When you have two side lengths of 2in and 4.5in What is the other side length?
nika2105 [10]

Answer:

The solution for the other side length is the interval

(2.5,6.5)

Step-by-step explanation:

I will assume that is a triangle

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ---> the measure of the third side

Applying the Triangle Inequality Theorem

1) 2+4.5 > x

6.5 > x

Rewrite

x < 6.5\ in

2) 2+x> 4.5

x> 2.5\ in

therefore

The solution for the other side length is the interval

(2.5,6.5)
