Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
The volume of the complex figure shown in the diagram is 56 m³.
<h3>
Volume</h3>
Volume is the amount of space occupied by a three dimensional object.
Volume = length * breadth * width
The volume of the big cube = length * breadth * width = 7 * 3 * 4 = 84 m³
The volume of the small cube cut out = length * breadth * width = 4 * 7 * (4 - 3) = 28 m³
Volume of the complex figure = 84 m³ - 28 m³ = 56 m³
The volume of the complex figure shown in the diagram is 56 m³.

Answer:
f(-5)
Step-by-step explanation:
because if X=-5 you just replace all of the X's in the equation. the whole equation would be f(-5) 45(-5)+40
A and D the rest of them is giving money away not saving it. Loaning it to a find is uncertain that they will give it back. Buying new bike is using money but it can save money is preticular if you are trying to save money I guess. Hiding it under a mattress is a good way to store money and save it for the furture. So the best choice that seem reasonable are A and D.
If the can's combined lips measure 38 inches and the adhesive overlaps by around 12 inches, the label's surface area will be 50 square inches.
<h3>What is the area?</h3>
The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
Given data;
Height of can,
Height of label,
Diameter,
The area of the label is;
A = ( overlap area + circumfereence ) h
Hence, the label's surface area will be 50 square inches.
