$\boxed{-7b-9k+6}$

<h2>Explanation:</h2>

We have the following expression:

$-4b+(-9k)-6-3b+12$

First of all, we need to open parentheses:

$-4b-9k-6-3b+12$

Next, combine like terms:

$-4b-3b-9k-6+12 \\ \\ \therefore \boxed{-7b-9k+6}$

A baseball player swings and hits a pop fly straight up in air to the catcher. the height of the baseball in meters t seconds af

Ludmilka [50]

$h(t)=-4.9t^{2}+34.3t+1
\\h'(t)=(-4.9t^{2}+34.3t+1)'=-9.8t+34.3
\\h'(t)=0
\\-9.8t+34.3=0
\\
\\t= \frac{34.3}{9.8} =3.5
\\
\\h_{max}=h(3.5)=-4.9\times3.5^{2}+34.3\times3.5+1=61.025$

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.

The edges of a cube increase at a rate of 2 cm divided by s. How fast is the volume changing when the length of each edge is 40

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

Let the edge of the cube be a .

Given

$\frac{da}{dt} = 2 cm/s$

Volume V = a³

$\frac{dV}{dt} = 3a^ 2\frac{da}{dt}$

= 3a² x 2

= 6a²

If a = 40 cm

$\frac{dV}{dt} = 6 \times 40\times40$

= 9600 cm³/s .

PLEASE HELP!!!!

<h3>Answer is 1.5 square meters</h3>

=================================================

Work Shown:

The portion of the fabric that is laying across the ground is 2 meters. The portion of the fabric from the ground to the highest point (along the fabric's edge) is 1.5 meters, half of that is 0.75 meters and this is the length of the shadow. We can see this by forming a 30-60-90 triangle. The hypotenuse is 1.5 meters, the short leg is 0.75 meters. The short leg is always half of the hypotenuse of any 30-60-90 triangle, and the short leg is opposite the 30 degree angle.

So this shadow has length of 2 meters and 0.75 meters, making its area be 0.75*2 = 1.5 square meters when the sun is directly overhead at 12 noon
