(d): y = mx+n

m = -2/3 ⇒ y = (-2/3)x +n

A(-4, 6) ∈ d ⇒ 6 = (-2/3)·(-4) +n ⇒ 6 = 8/3 +n ⇒

⇒ n = 6 - 8/3 ⇒ n = 10/3

Now, we have:

y = (-2/3)x +10/3

If a ball is thrown directly upward with a velocity of 50ft/s, it's height (in feet) after t seconds is given by y=50t-16t^2 wha

Tomtit [17]

Answer:

39.0625 ft

Step-by-step explanation:

Since the function is a quadratic representing height, and the coefficient of the t² is negative, the vertex of the parabola will be the maximum height achieved by the ball.

The general form for a quadratic equation is ax² + bx + c, here a is -16, and b is 50

To find the x coordinate of the vertex, use x = -b/(2a)

We have x = -50/[2(-16)]

x = -50/-32

x= 25/16

Now plug that into the equation to find the y value, which will be the height...

y = 50(25/16) - 16(25/16)²

y = 1250/16 - 16(625/256)

y = 1250/16 - 625/16

y = 625/16

y = 39.0625

LUCKY_DIMON [66]

Answer:

The correct option is the second option;

a. Division property of equality

b. Symmetric property of congruency

c. Multiplication property of equality

Step-by-step explanation:

a. For the equation in part a., we have;

6·a = 30

Therefore;

6·a/6 = 30/6

a = 5

Which is of the form, if a = b then a ÷ c = b ÷ c, which is the division property of equality

b. For the relationship in part b., we have;

∠ABC ≅ ∠LMN

∠LMN ≅ ∠ABC

The above relationship is of the form, if a ≅ b then b ≅ a, which is the symmetric property of congruency

c. For the equation in part c., we have;

$\dfrac{2}{3} \cdot \left (x - 6\right ) = 8$

Multiply both sides by 3, to get;

$3 \times \dfrac{2}{3} \cdot \left (x - 6\right ) = 3 \times 8 = 24$

Cancel like terms on the left hand side of the equation, to get;

2·(x - 6) = 24

Which is of the form, if a = c, then a × c = b × c which is the multiplication property of equality
