Distance H in feet that an object falls in T seconds is modeled by the formula H equals 16 T2 squared if you drop a rock from a cliff 1960 above the water how long will it take the rock to hit the water
Answer:
after 11.07secs
Step-by-step explanation:
Given the height of an object modeled by the equation
H = 16T² - 1960
The height of the object on the surface of water is zero, hence H = 0
Substitute
0 =16T² - 1960
Swap
16T² - 1960 = 0
16T² = 1960
T² = 1960/16
T² = 122.5
T = 11.07
Hence the rock will hit the surface of the water after 11.07secs

Round 19.798 to the nearest tens place.
Answer:
20
Step-by-step explanation:
Hope this helps!!!!
If it is tens its 20
If it ins tenth its 19.8
To round 19.798 to the nearest tenth consider the hundredths’ value of 19.798, which is 9 and equal or more than 5. Therefore, the tenths value of 19.798 increases by 1 to 8.
19.798 rounded to the nearest tenth = 19.8
Answer:
19.8
Step-by-step explanation:
I'm not sure if you mean "tens" or "tenths" so I assumed "tenths".
If it was "tens" then it would be 20.

What is the distance between points (3.3) and Wc-2, -3)
Round to the nearest tenth if necessary.
Answer:
7.81 u
Step-by-step explanation:
Given :-
Two points (3,3) and (-2,-3) is given to us.And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}
[tex]:\implies[/tex] D =√[ (3+2)² +(-3-3)²]
[tex]:\implies[/tex] D =√[ 5² +6²]
[tex]:\implies[/tex] D =√[ 25 +36]
[tex]:\implies[/tex] D = 61
[tex]:\implies[/tex] D = 7.81
Hence the distance between the two points is 7.81 units .Please help quick. 100 points ;)

Determine whether each given pair of end points lies on the same horizontal or vertical line. If so, find the length of the line segment that joins the pair of points. If not, explain how you know the points are not on the same horizontal or vertical line.
Answer:
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
They lie on the same horizontal line
Distance = 11 units
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
They do not lie on the same vertical or horizontal line
Step-by-step explanation:
Given
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
Required
Determine if the points lie on the same vertical or horizontal line
A point is represented as: [tex](x,y)\\[/tex]
For a pair to lie on the same horizontal line, then they must have the same x values i.e. [tex](x,y_1)\ and\ (x,y_2)[/tex]For a pair to lie on the same vertical line, then they must have the same x values i.e. [tex](x_1,y)\ and\ (x_2,y)[/tex]Using the above illustration, we have:
[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]
The above have the same x values (0), hence they lie on the same horizontal line.
The distance between them is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]d = \sqrt{(0-0)^2 + (-2 - 9)^2}[/tex]
[tex]d = \sqrt{0^2 + (-11)^2}[/tex]
[tex]d = \sqrt{0 + 121}[/tex]
[tex]d = \sqrt{121}[/tex]
[tex]d = 11[/tex]
The distance between them is 11 units
[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]
The above pair do not have the same x value and they do not have the same y value.
Hence, they do not lie on the same vertical or horizontal line

Monica has 2 gallons of milk to make milkshakes. Each milkshake contains 1 cup of milk. There are 128 ounces in 1 gallon and 8 ounces in 1 cup.
How many cups of milk does Monica have to make milkshakes? .
Answer: 32 cups of milk
Step-by-step explanation:
The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.
There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:
= 128 * 2
= 256 ounces
Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:
= 256 / 8
= 32 cups of milk
