X(2x-1)/(2x-1)
(2x^2-x)/(2x-1)
(2xx-x)/(2x-1)
So you can remove something if it's the same under and above.

It would be D, because if you divide them you would end up with something that looks like this:

x (2x-1)
----------
(2x-1)

Then if you cross out both of the two 2x-1, all that is left is the x.

A baseball is thrown in a parabolic arc. It's position above the ground at a given point in time

FinnZ [79.3K]

If the ball was thrown straight up at 24 ft/sec when it was 5 ft above the ground, the ball reached a maximum height of 7.25 m

Discriminant of quadratic equation ( ax² + bx + c = 0 ) could be calculated by using :

From the value of Discriminant , we know how many solutions the equation has by condition :

D < 0 → No Real Roots

D = 0 → One Real Root

D > 0 → Two Real Roots

$\texttt{ }$

An axis of symmetry of quadratic equation y = ax² + bx + c is :

$\large {\boxed {x = \frac{-b}{2a} } }$

Let us now tackle the problem!

$\texttt{ }$

<u>Given:</u>

$p(t) = 3gt^2 + v_ot + p_o$

$p(t) = 3(-32)t^2 + 24t + 5$

$p(t) = -64t^2 + 24t + 5$

<u>Asked:</u>

$p_{max} = ?$

<u>Solution:</u>

<em>At the maximum height , velocity is 0 m/s:</em>

$v = \frac{dp(t)}{dt}$

$v = \frac{d}{dt} ( -64t^2 + 24t + 5 )$

$v = (-64)(2)t^{2-1} + 24$

$v = -128t + 24$

$0 = -128t + 24$

$128t = 24$

$t = 24 \div 128$

$t = 3 \div 16$

$t = 0.1875 \texttt{ s}$

$\texttt{ }$

$p(t) = -64t^2 + 24t + 5$

$p(0.1875) = -64(0.1875)^2 + 24(0.1875) + 5$

$p(0.1875) = 7.25 \texttt{ m}$

Complete the function f(x)=2x-5

Grace [21]

Replace X in the equation with the values in the table and calculate:

2X-5:

2(-4) -5 = -8 -5 = -13

2(-2)-5 = -4-5 = -9

2(1)-5 = 2-5 = -3

2(3)-5 = 6-5 = 1

2(5)-5 = 10-5 = 5

A student estimates that it takes 2 hours to read 25 pages. At this rate, how many hours will she need to read 425 pages?

wolverine [178]

Answer:

34 hours

Step-by-step explanation:

2:25 = x:425

25/2 = 12.5

425/12.5 = 34

so it is 34:425

She will need to read for 34 hours to read 425 pages
