We are given with the function that expresses the height of the football over time in the equation <span>h(x) = -16t^2 + 64t. To determine the axis of symmetry, we determine the time when it reaches the maximum height. we derive the equation and equate to zero to get t. -32t +64 = 0. t is equal to 2 seconds. Substituting, to the original equation, h(x) is 64. Hence the axis of symmetry is y = 32. </span>
Set it up as an equation:
m=miles she can drive
42+.35m=70
Subtract the 42, so
.35m= 28
Divide by .35, so
m=80
She can drive 80 miles
Answer:
1 1/9 miles
Step-by-step explanation:
If john swims 5/12 of a mile in 3/8 of an hour, then;
5/12 miles = 3/8 hours
TO get the number of miles he swims in an hour, we will say;
x miles = 1 hour
Equating both expressions
5/12 miles = 3/8 hours
x miles = 1 hour
Cross multiply
3/8 x = 5/12
3x/8 = 5/12
3x * 12 = 5 * 8
36x = 40
x = 40/36
x = 10/9
x = 1 1/9
The amount he swims in an hour is 1 1/9 miles
Answer:
Both A and B
Step-by-step explanation:
A set of ordered pairs is not a function if there is a repeating output (Y value.)
Y values of A= 5, 2, -2, -5.
Y values of B= 2, -2, 4, -3.
There are no repeating outputs.
