Answer:
"the difference of a number and eight, divided by ten"
x-8÷10
20 + 25x = 50 + 15x
25x - 15x = 50 - 20
10x = 30
x = 30/10
x = 3...ur answer would be 3 training sessions
Answer:
Time it took for the walker to land on net = 1.75 seconds
Step-by-step explanation:
Given:
Height above the ring as a function of time is give as:
Height of the tightrope walker after he falls = 11 feet
Plugging the height in order to find the time it took for the walker to land on net.
Adding to both sides.
Subtracting both sides by 11.
Dividing both sides by 16.
Taking square root both sides.
Since time is always positive
∴
∴ Time it took for the walker to land on net = 1.75 seconds
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function
Equation is in the form of y=ax^2+bx+c
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
, factor out negative
Take out negative sign in common
