A rock falls off a balcony. It’s height(in feet)is given by the formula f(x)= -16t^2+12.5t+150, where t is measured in seconds.
ELEN [110]

Answer: 3.47\ seconds

Step-by-step explanation:

Given the following function:

f(x)= -16t^2+12.5t+150

You need to follow these steps in order to solve the exercise:

1. Substitute f(x)=0:

0= -16t^2+12.5t+150

2. Now you need to apply the Quadratic formula. This is:

x=t=\frac{-b\±\sqrt{b^2-4ac} }{2a}

In this case, you can identify that:

a=-16\\b=12.5\\c=150

Then, you can substitute these values into the formula:

t=\frac{-12.5\±\sqrt{(12.5)^2-4(-16)(150)}}{2(-16)}

3. Evaluating, you get:

t_1=3.47\\\\t_2=-2.69

4. You must choose the positive value. Then:

t=3.47\ seconds

Suppose three lamp posts exist on a straight
Andrews [41]

Answer:

324 ft

Step-by-step explanation:

1. We know there are 3 points (A, B, and C)

so far. We also know B is in the middle of A and C.

A----B----C

2. Reading further, post B is 2x as far from C as it is from A.

A----B----.----C

3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).

A----B----.----C

<- 486ft ->

4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.

A----B----.----C

1 2 3

5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.

A----B----.----C

162 162 162

6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.

7. Make sure to put it into the correct form to answer (ft) and there you go!

Hope I helped! :))
