Answer:

1/2

Step-by-step explanation:

In slope intercept form (y=mx+b), "m" represents the slope or constant of proportionality.

1/2 is in m's spot, so 1/2 is the constant of proportionality.

A golfer attempts to hit a golf ball over a valley from a platform above the groun
leonid [27]

Answer: NO

Step-by-step explanation:

The functions that models the height of the ball is given as

h(t) = -5t2 + 40t + 100

Where

a = -5, b = 40, c = 100

The time the ball will reach the maximum height will be the vertex of the parabola. At the line of symmetry, the time t will be:

t = -b/2a

Substitute b and a into the formula above.

t = - 40 / -5 = 8

Substitute 8 for t in the function f(t)

h(t) = - 5(8)^2 + 40(8) + 100

h(t) = -5(64) + 40(8) + 100

Open the bracket

h(t) = -320 + 320 + 100

h(t) = 100

The maximum height of the ball is 100m

Given that the power lines is 185 metres above the ground. The golf ball will therefore not hit power lines because the maximum height the ball can go is 100 metres

A company designs a logo using a kite figure around the letter t. The logo is 12 centimeters wide and 16 centimeters tall. What
Temka [501]

Answer:

96 sq. cm.

Step-by-step explanation:

A "kite" has 2 diagonals, which are the "width" and "height" of the kite.

Using diagonals, the area of a kite is given by  A=\frac{pq}{2}

Where

A is the area

p,q are the width and height, respectively

From the problem given, p is 12 and q is 16, so the area is:

A=\frac{pq}{2}\\A=\frac{(12)(16)}{2}\\A=96

Thus, the area is 96 sq. cm
