Elizabeth and Markus are playing catch. Elizabeth throws the ball first. The height of the ball can be modeled by the equation h

= −8t(t − 9), where h is the height of the ball in feet and t is the time in seconds. Markus is distracted at the last minute and looks away. The ball lands at his feet. If the ball travels at a rate of 3.5 feet per second, how far is Markus standing from Elizabeth when the ball hits the ground?

This is an exponential equation that can be represented by the following:

f(x) = a(b)^x

In this case...

25143 = a(0.66)^3

25143 is the population after 3 hours.

3 is the amount of time in hours.

0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).

We must solve for a, which is the initial population.

First, simplify (0.66)^3 to 0.2874.

25143 = 0.2874a

Now divide both sides by 0.2874 to isolate a.

a = 87455

There were initially 87,455 people within the city. I wouldn't want to be in that place!

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2
JulsSmile [24]

Answer:

3x^2 + 9x  +9

Step-by-step explanation:

Given

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Required

The result in standard form

We have:

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Remove brackets

7x + 8 + 2x^2 + 2x + 1 + x^2

Collect like terms

7x+ 2x  + 8 + 1 + 2x^2+ x^2

9x  + 9+ 3x^2

The standard form of a quadratic equation is:

ax^2 + bx + c

So, we have:

9x  + 9+ 3x^2

3x^2 + 9x  +9

Find the equation line<br> (5,6), (4,7)
34kurt

Answer:

x+y=11

Step-by-step explanation:

Here we are given two coordinates through which our lines passes through. Now we are going to use the two point form to find the equation of the line.

The two point form is given as

\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}

Here we are given two coordinates . Thus replacing them in the formula and simplifying it will give us the equation of the line.

\frac{y-6}{x-5}=\frac{7-6}{4-5}

\frac{y-6}{x-5}=\frac{1}{-1}

(y-6)=-(x-5)

y-6=-x+5

adding x and 6 on both sides we get

x+y=11

Hence this is our equation of the line passing through (5,6) & (4,7)
