Answer:
the projectile reached a maximum height of 27.6 meters in 2.4 seconds and it took 5.0 seconds for it to hit the ground
Step-by-step explanation:
to find the vertex you can find the axis of symmetry first
that equation is -b/2a
-19/-8 = 2.375
then you take this and plug it in
-4(2.375)^2 + 19*2.375 + 5
that gives you 27.5625
then you have to find when it hits the ground
you can factor to find this out
-4t^2 + 19t + 5
4t^2 - 19t - 5
4t^2 + t - 20t - 5
t(4t + 1) -5(4t +1)
(t - 5)(4t + 1)
t = {5, -1/4}
we can only take positive time so it took 5 seconds
the answer is the second one
To produce the word form and standard form of the value given we can first
establish the simplest and clearest form by turning the given numerical value
into a single number
1. 70, 000, 000 + 400, 000 + 10, 000 +
8, 000 + 500 + 30 + 9 = 70, 418, 539
2. Hence, the word form will be
seventy million four hundred eighteen thousand five hundred and thirty-nine
Answer:
List from least to greatest:-16,-10,-3,5
List from closest to zero to the very far:-3,5,-10,16
Step-by-step explanation:
In order to know if the answer is accurate,draw a number line of directed numbers...the very far negative numbers,are said to be the least than the numbers almost close to zero...
The consecutive even integers are 8, 10 and 12.
<h3>How to calculate the value?</h3>
Let the integers be x, x + 2, and x + 4.
Therefore, the equation will be:
6(x) = x + 2 + x + 4 + 26
6x = 2x + 32
Collect like term
6x - 2x = 32
4x = 32
Divide
x = 32/4.
x = 8
The numbers are 8, 10 and 12.
