Write an equation in standard form for the line that passes through (4, 4) and has a x-intercept of 3?
Nikolay [14]

Answer:

y=4(x-3)

Step-by-step explanation:

if x=3, subtract 3 from each side to get x-3=0

point (4, 4). That is, when x=4, y=4.

Plug those in and solve for a.  

y=a(x-3)

4=a(4-3)

4=a(1)

4=a

 Thus,  

y=4(x-3)

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the fence into the court. The path
jeka57 [31]
To solve this exercise you must follow the proccedure below:

 a) Find the maximum height of the tennis ball:

  You have that the path of the ball can be represented by h=-16t²<span>+18t+5. Then:

 t=-b/2a
 t=-18/2(-16)
 t=0.562
</span>
 h=-16t²+18t+5
 h=-16(0.562)²+18(0.562)+5
 h=10.06

 b) How long will it take to reach the ground?

 h=-16t²+18t+5

 h=0

 -16t²+18t+5=0

 You must apply the quadratic equation: 

 t=(-b±√(b^2-4ac))/2a

 a=-16
 b=18
 c=5

 When you substitute the values, you obtain:

 t=1.35
