Answer:
is scientific notation of 0.0765
Step-by-step explanation:
For scientific notation , follow the following notation:
-------->(equation 1)
Let,
In standard form
As decimal point move 2 places from left to right, therefore
b = -2
Put the value of 'a' and 'b' in (equation 1)
is scientific notation of 0.0765
It’s the second one, A has the box yellow yellow, but there is no yellow card
The width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
<u>Explanation:</u>
Given:
Two rectangles are proportional.
Length and width of 1 rectangle = 6 : 8
Dimensions of the other rectangle = ?
Let length and width of the other rectangle be x : y
According to the question:
So, the width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
