Can you also use the LCM of the denominator of the fraction rewrite the difference 8\15-1\6? What is the difference?

A ball is thrown up into the air from a building modeled by the equation:

Arlecino [84]

Answer:

After two seconds

h(2) = -16(2^2) + 115(2) + 19

h(2) = -64 + 115(2) +19

h(2) = 185

Let me know if this helps!

I need help ASAP <br> Someone please help me questions 7&8

attashe74 [19]

For #7, one line should have the y-intercept of -2 and a slope of 2/3 and the other line's y-intercept is 1 and its slope should be -5.

In the image provided, the red line represents 2/3x - 2 and the blue line represents -5x + 1.

8) Organize the information you are given.

*Savannah is 24 years older than Ryan.

So, Ryan's age + 24 = Savannah's age.

*Sebastian is 5 times as old as Ryan.
So, Ryan's age × 5 = Sebastian's age.

*Savannah and Sebastian are twins. They have the same age.
So, Savannah's age = Sebastian's age

Let x represent Ryan's age.

Write the equation based on the information you are given.

x + 24 = x(5)

x + 24 = 5x

Solution: D) 24 + x = 5x

D.sqrt(2+x^/2)<br> Solve this question please

lidiya [134]

Answer:

Option a.

Step-by-step explanation:

By looking at the options, we can assume that the function y(x) is something like:

$y = \sqrt{4 + a*x^2}$

$y' = (1/2)*\frac{1}{\sqrt{4 + a*x^2} }*(2*a*x) = \frac{a*x}{\sqrt{4 + a*x^2} }$

such that, y(0) = √4 = 2, as expected.

Now, we want to have:

$y' = \frac{x*y}{2 + x^2}$

replacing y' and y we get:

$\frac{a*x}{\sqrt{4 + a*x^2} } = \frac{x*\sqrt{4 + a*x^2} }{2 + x^2}$

Now we can try to solve this for "a".

$\frac{a*x}{\sqrt{4 + a*x^2} } = \frac{x*\sqrt{4 + a*x^2} }{2 + x^2}$

If we multiply both sides by y(x), we get:

$\frac{a*x}{\sqrt{4 + a*x^2} }*\sqrt{4 + a*x^2} = \frac{x*\sqrt{4 + a*x^2} }{2 + x^2}*\sqrt{4 + a*x^2}$

$a*x = \frac{x*(4 + a*x^2)}{2 + x^2}$

We can remove the x factor in both numerators if we divide both sides by x, so we get:

$a = \frac{4 + a*x^2}{2 + x^2}$

Now we just need to isolate "a"

$a*(2 + x^2) = 4 + a*x^2$

$2*a + a*x^2 = 4 + a*x^2$

Now we can subtract a*x^2 in both sides to get:

$2*a = 4\\a = 4/2 = 2$

Then the solution is:

$y = \sqrt{4 + 2*x^2}$

The correct option is option a.

The nakagin capsule tower has 140 modules and is 14 stories high if the modules were divided evenly among the number of stories

ArbitrLikvidat [17]

To determine the number of modules that is in each story, we simply divide the number of modules by the number of stories.
= 140 / 14
Simplifying,
= 10 modules / story
Therefore, by even distribution we note that there are 10 modules per story.
