Given numbers 2 ,5,11, 4.5, 1/10, V3 then

Black_prince [1.1K]

Answer:

a. pick two between 2,5 or 11, they are all primes.

b. it's 11 since

$11 {}^{2} = 121$

c. that's

$18 \times \frac{25}{100} = 4.5$

(or think about it as half the half of 18, so half of 9)

$\sqrt{3}$

Rest can be written as a fraction

4x+4y=0 -10x— 4y=-18

-BARSIC- [3]

we can use elimination to solve these

add the two equations together

4x+4y=0

-10x— 4y=-18

--------------------

-6x = -18

divide each side by -6

x = 3

4x + 4y = 0

substitute in x=3

4*3 + 4y =0

12 + 4y =0

subtract 12 from each side

4y=-12

divide by 4

y = -3

x=3, y= -3

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic fun

Archy [21]

Answer:

The maximum height of the ball is 380.25 feet in the air.

Step-by-step explanation:

The quadratic function:

$h(t)=-16t^2+132t+108$

Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.

We want to determine the maximum height of the ball.

Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.

Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:

$\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)$

In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:

$\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125$

So, the maximum height occurs after 4.125 seconds of the ball being thrown.

To find the maximum height, substitute this value back into the equation. Thus:

$h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}$

The maximum height of the ball is 380.25 feet in the air.
