You can use the equation d = 16t^2 (note: t is raised to the second power or squared) to determine the time t in seconds that it

takes a dropped object to fall a distance of d feet. How long (in seconds) does a fall of 224 feet take? Round your answer to the nearest tenth. *

Answer:

The time the object takes to fall on the ground from 224 feet is 3.74 s.

Step-by-step explanation:

In this case we have a known quantity, the distance of the fall that is 224 feet and a equation that represents the motion of this fall that is d = 16t^2. We wish to find the time it'll take this object to fall, so we can solve this equation for t. It goes as follows:

d = 16t^2

d/16 = t^2

t^2 = d/16

t = \sqrt(d/16)

t = [\sqrt(d)]/4 = [\sqrt(224)]/4 = 14.97/4 = 3.74 s

where \sqrt is the square root of the number.

Answer:

3.7 seconds

Step-by-step explanation:

We were provided with the equation d=16t² so as to determine the time t in seconds it takes for an object dropped to fall a distance of d-feet.

The question says how long(in seconds does)it take for a fall of 224 feet.

16t²=d

D= 224(substitute in the equation)

16t²= 224

t²= 224/16

t=√14

t= 3.7 seconds

A seamstress uses 3/4 yards of material to make a uniform top for band members. If there are 6 3/4 yards of material left on the
dalvyx [7]

Answer:

She can make 9 uniform tops from the material left.

Step-by-step explanation:

Given:

Yards of material left on the bolt = 6\frac{3}{4}

Material requirement for a uniform top for band members = \frac{3}{4}\ yd

To find the number of tops that can be made from the material left.

Solution:

In order to find the number of tops that can be made from 6\frac{3}{4} yards of material, we need to divide 6\frac{3}{4}\ yd  by  \frac{3}{4}\ yd.

Number of uniform tops that can be made is given as:

⇒ 6\frac{3}{4}\div \frac{3}{4}

We first convert mixed number to fractions.

⇒  \frac{27}{4}\div \frac{3}{4}

To divide fractions the fractions are multiplied after flipping the divisor.

⇒ \frac{27}{4}\times \frac{4}{3}

⇒ \frac{27}{3}

⇒ 9

Thus, she can make 9 uniform tops from the material left.

Solve by factoring:<br><br> 5x^2 + 19x + 12 = 0
Mariulka [41]

When solving polynomial equations, first set the equation

equal to zero, then check for a Greatest Common Factor.

Since there is no greatest common factor, this will make life a

little bit more difficult because we will have to factor the trinomial.

First, find all possible factors for constant term.

I have listed these in red below.

Make sure to reverse the factors since in each binomial,

the first term is different so we need to reverse the factors.

The factors of 5x² will just be 5x and z.

After finding factors for the constant and the leading

coefficient for your trinomial, we can eliminate some factors.

If you have an odd coefficient on the middle term,

you can eliminate any pairs of even factors.

So the group I crossed out in purple below will be eliminated.

Another strategy is to use factors a little closer together.

So I would go with the 4 and 3 group.

Surely enough, our trinomial does factor with the 4 and 3.

Now set the factored trinomial equal to 0.

Then use zero product property and you have your answer.
