Answer:

-144

Step-by-step explanation:

a³ + 2abc - 5c² = (3)³ + 2(3)(7)(-3) - 5(-3)²

= 3³ + (-126) - 5(-3)²

= 27 + (-126) - 45

= (-99) - 45

= -144

your welcome

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>

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

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

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

$v = -128t + 24$

$0 = -128t + 24$

$128t = 24$

$t = 24 \div 128$

$t = 3 \div 16$

$t = 0.1875 \texttt{ s}$

$\texttt{ }$

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

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

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

A glass vase is shaped like a cylinder and has a radius of 2.5 inches. The vase holds 170 cubic inches of water. How tall is the

Sergeu [11.5K]

So to find a cylinder's volume, you do πr^2*h = volume
So we can fill in a few of the elements.
3.14 * 2.5 ^2 * h = 170
And then we can continue to simplify it.
3.14 * 6.25 * h = 170
19.625 * h = 170
And then to find h,
170/19.625 = about 8.66

Explain how you could use the interactive table to tell if

Tasya [4]

Answer:

Tables are essentially the source for all the charts. They are best used for comparison, composition, or relationship analysis when there are only few variables and data points. It would not make much sense to create a chart if the data can be easily interpreted from the table.

The tables help us to compare the values of those two sets of the data that have been presented in different ways.
