There are 9 possible combinations, because you can have 3 main dishes, and each of thise have 3 side dishes that can go with them. I hope this helps! Could I possibly get brainliest.

A baseball diamond is a square with side 90 ft. A batter hits the ball and runs toward first base with a speed of 31 ft/s. (a) A

Afina-wow [57]

Answer:

13.86 ft/sec

Step-by-step explanation:

If we let x = distance batter has run at time t and D = distance from second base to the batter at time t, then we know $\frac{dx}{dt}=31 ft/s$ and we want $\frac{dD}{dt}$ when he is halfway (at x = 45).

Using Pythagoras theorem

$D^2=90^2+(90-x)^2\\\text{Differentiating with respect to t}\\2D\frac{dD}{dt}=0+2(90-x)(-1)\frac{dx}{dt}\\2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}$

When x=45

$D^2=90^2+(90-x)^2\\D^2=90^2+(90-45)^2\\D^2=10125\\D=\sqrt{10125}$

$2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}\\2\sqrt{10125}\frac{dD}{dt}=-2(90-45)(31)\\\frac{dD}{dt}=\frac{-2(45)(31)}{2\sqrt{10125}} =-13.86ft/s$

Thus, when the batter is halfway to first base, the distance between second base and the batter is decreasing at the rate of about 13.86 ft/sec.

Solving a Quadratic Equation

Dafna1 [17]

Answer:

The factored form of the equation is (x + 4)(x – 6) = 0.

Step-by-step explanation:

(x – 4)(x + 2) = 16

Foil the left side

x^2 +2x-4x-8 =16

Combine like terms

x^2 -2x-8 = 16

Subtract 16 from each side

x^2 -2x-8-16 =16-16

x^2 -2x-24 =0

Factor the left hand side

What two numbers multiply to -24 and add to -2

-6*4 =-24

-6+4 = -2

(x-6) (x+4) =0

Solving using the zero product property

x-6 =0 x+4=0

x=6 x=-4

What is the equation of the line that passes through (0, -2) and has a slope of O?

Dmitriy789 [7]

Answer:

The equation of the line that passes through (0, -2) and has a slope of 0 is $\mathbf{y=-2}$

Step-by-step explanation:

We need to find the equation of the line that passes through (0, -2) and has a slope of 0?

The equation of line can be expressed in slope-intercept form $y=mx+b$ where

m is slope
b is y-intercept

We need to find slope and y-intercept for the equation.

We are given slope = 0 so, m = 0

Now, y-intercept can be found using slope m=0 and point (0,-2)

$y=mx+b\\-2=0(0)+b\\-2=b\\or\\b=-2$

So, we get y-intercept: b = -2

Now, the equation of the line having slope m=0 and y-intercept b=-2 is:

$y=mx+b\\y=0(x)-2\\y=-2$

So, the equation of the line that passes through (0, -2) and has a slope of 0 is $\mathbf{y=-2}$
