(a)

slope of f(x):

We can select any two points to find slope

(0,-3) and (1,0)

now, we can use slope formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{0+3}{1-0}

m=3

slope of g(x):

g(x)=4x-5

we can compare it with slope intercept form of line

g(x)=mx+b

we get

m=4

so, we can see that slope of f(x) is 3 while slope of g(x) is 4

so, slope of g(x) is greater than slope of f(x)

(b)

y-intercept of f(x):

we know that y-intercept is value of y when x=0

we are given point (0,-3)

so, y-intercept is -3

y-intercept of g(x):

we know that y-intercept is value of y when x=0

so, we can plug x=0 and find y

g(0)=4*0-5

y=-5

so, y-intercept is -5

Since, -3 is greater than -5

Hence , y-intercept of f(x) has greater value.........Answer

2. Mourette is a member of her high school golf team. She hits a golf ball
Llana [10]

Answer:

a. h = 60t − 4.9t²

b. 12.2 seconds

c. 183.7 meters

Step-by-step explanation:

a. Given:

y₀ = 0 m

v₀ = 60 m/s

a = -9.8 m/s²

y = y₀ + v₀ t + ½ at²

h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²

h = 60t − 4.9t²

b. When the ball lands, h = 0.

0 = 60t − 4.9t²

0 = t (60 − 4.9t)

t = 0 or 12.2

The ball lands after 12.2 seconds.

c. The maximum height is at the vertex of the parabola.

t = -b / (2a)

t = -60 / (2 × -4.9)

t = 6.1 seconds

Alternatively, the maximum height is reached at half the time it takes to land.

t = 12.2 / 2

t = 6.1 seconds

After 6.1 seconds, the height reached is:

h = 60 (6.1) − 4.9 (6.1)²

h = 183.7 meters
