Given:
The height of ball is represented by the below function:

To find:
The number of seconds it will take to reach the ground.
Solution:
We have,

At ground level, the height of ball is 0, i.e.,
.

Taking out greatest common factor.


Splitting the middle term, we get



Using zero product property, we get
and 
and 
Time cannot be negative, so
.
Therefore, the ball will reach the ground after 2 seconds.
B. If you were to solve for x, the values would be x=1.5275 and x=-1.5275.
Answer:
y = -4/5x + 7/5
Step-by-step explanation:
Use slope intercept form to find the equation for the line:
y=mx+b
y= -4/5x + 7/5
Hey there!!
Given equation :
... -4 ( x + 10 ) - 6 = -3 ( x - 2 )
Using the distributive property :
... -4x - 40 - 6 = -3x + 6
Combining like terms :
... -4x - 46 = -3x + 6
Adding 46 on both sides :
... -4x = -3x + 52
Adding 3x on both sides :
... -x = 52
... x = -52
Hope helps!
F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2
