Researchers in Antarctica discovered a warm sea current under a glacier that is causing the glacier to melt. The ice shelf of th

e glacier had a thickness of approximately 450 m when it was first discovered. The thickness of the ice shelf is decreasing at an average rate of 0.06 m per day. Which function can be used to find the thickness of the ice shelf in meters x days since the discovery?

The length of a rectangle is 15 ft greater than its width. If each dimension is decreased by 2 ft, the area will be decreased by
padilas [110]

Answer:

length = 35ft, width = 20ft

Step-by-step explanation:

We are working with length (L), width (W), and area (A). We are asked to find the 2 dimensions. The question tells us that L = W + 15, so we can express L in terms of W. However, we still don't know what A is. Since we have 2 unknowns, we somehow need to develop 2 equations to get a solvable system.

We can set up the first equation using the relationship between L and W:

W(W+15)=A

We can set up the second equation using the information in the second sentence:

(W-2)(W+13)=A-106

Now we can plug the first equation, already isolated for A, into the second equation and solve for W:

(W-2)(W+13)=W(W+15)-106\\W^2+11W-26=W^2+15W-106\\4W=80\\W=20

A pretty nasty-looking equation actually becomes pretty easy to solve. We know the length is 15ft greater than the width, so if W=20, L=35.

What is the value of p in the question below. 10x9/2x4= px 5
ycow [4]

Answer:

p = 5

Step-by-step explanation:

We have that:

\frac{x^{a}}{x^{b}} = x^{a-b}

So

\frac{x^{9}}{x^{4}} = x^{9-4} = x^{5}

10/2 = 5

Then

\frac{10x^{9}}{2x^{4}} = 5x^{9-4} = 5x^{5}

Finding p:

5x^{5} = px^{5}

p = \frac{5x^{5}}{x^{5}}

p = 5
