Here, Function: h(t)= -16t² + 70t + 40
So, put the value of t, (time at which you want to calculate the height)
h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94
Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116
h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106
In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)
Hope this helps!
Answer:
a
Step-by-step explanation:
do 2 x 2 you should get the right answer
Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2
Combining equation 1 and 2, we get
( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12
Now, evaluating the value of Y in equation 1 we get,
X + 12 = 43
X = 31
Therefore, Fred is 31years old and Natalie is 12 years old.
