Answer:
a) t = 2 seconds
b) 6.05 meters
Step-by-step explanation:
I prefer a graph for questions like this, but I have attached a table, too. Here, the table is created using a graphing calculator to evaluate the function. A spreadsheet can do this nicely, too.
The maximum height occurs at t=0.9 seconds, and the ball hits the ground at a time that is slightly more than double that, 2.0 seconds.
The maximum height is 6.05 meters.
Hey there!!
In the figure, we have two angles. And the sum of these both angles is mentioned as 134°.
Angle ABC is (4x-1)° and Angle CBD is (6x+5)°
Angle ABC + Angle CBD = 134°
... 4x - 1 + 6x + 5 = 134
... 10x + 4 = 134
... 10x = 134-4
... 10x = 130
... x = 130 ÷ 10
... x = 13
Now, we will have to find the angle ABC and the angle ABC is given as 4x-1.
Hence, angle A =
... 4(13)-1
... 52-1
... 51.
<em>Hence, the required answer is 51°.</em>
Hope my answer helps!
Answer:
$480
Step-by-step explanation:
12x12 = 144 sq feet.
144 sq feet = 16 sq yards.
$30 x 16 = $480
-2 + 5(3x-4) =19 the answer is x = 2.733
Answer:
x=4, x=-4
Step-by-step explanation:
x^2-16=0
Add 16 to both sides;
x^2-16+16=0+16
Simplify;
x^2=16
x=, x
=4
factor the number;16
=
-
Factor the number 16;
=-4
