Answer:
[tex]1.5\; \rm s[/tex].
Step-by-step explanation:
The person in this question is in the air whenever the height is greater than [tex]0[/tex].
The graph of [tex]y = -16\, t^{2} + 24\, t[/tex] is a parabola opening downwards. Rearrange and find values of [tex]t[/tex] that would set this expression to [tex]0[/tex].
[tex]\begin{aligned}y &= -16\, t^2 + 24\, t \\ &= t\, (-16\, t + 24) = -8\, t\, (2\, t - 3)\end{aligned}[/tex].
The first factor, [tex]t[/tex], suggests that [tex]t = 0[/tex] would set this expression to [tex]0[/tex]- quite expected, since the person is on the ground right before jumping.
The second factor, [tex](2\, t - 3)[/tex], suggests that [tex]2\, t = 3[/tex] (in other words, [tex]t = 3/2 = 1.5[/tex]) would also set this expression to [tex]0[/tex]. Hence, this person would be once again on the ground [tex]1.5[/tex] seconds after jumping.
Hence, this person is in the air between [tex]t = 0[/tex] and [tex]t= 1.5[/tex] for a total of [tex]1.5\; \rm s[/tex].

Find SR
A) 4
B) 5
C) 7
D) 9
9514 1404 393
Answer:
C) 7
Step-by-step explanation:
We have ...
TS +SR = 19
SR +RQ = 13
Adding these two equations together, we have ...
TS +2·SR +RQ = 19 +13 = 32
We also have ...
TS +SR +RQ = 25
Subtracting this from the equation above, we have ...
(TS +2·SR +RQ) -(TS +SR +RQ) = 32 -25
SR = 7

Rotate triangle P 90° clockwise about the point (2, -1).
Please screenshot this and send me the answers cuz I really need help :(
Answer: (2,0), (2,1), and (6,1)
Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.
I hope this helps! Have a nice day.

Step-by-step explanation:
the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
What is the value of x? (giving brainliest and thanks to all!)
Answer:
x = 12
Step-by-step explanation:
Given a line parallel to a side of the triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{5}{10}[/tex] ( cross- multiply )
10x = 120 ( divide both sides by 10 )
x = 12
Math question part 2 show work thanks Jim !!
Part (b)
The scale 1 cm = 2 m means we'll multiply whatever the cm distance is by 2 to get the meter distance in real life.
The shed is 3 cm by 3 cm on paper. It corresponds to 6 meters by 6 meters in real life.
----------
The cement pad is 6 meters by 10 meters in real life because it's originally 3 cm across and 5 cm vertical. We double each dimension as done before, and replace "cm" with "m".
----------
The hot tub is a circle so we don't get an exact measurement here. But we can determine a good estimate. It appears it's 2 cm across and 2 cm vertical. So that corresponds to 4 meters by 4 meters
=========================================
Part (c)
On paper, the distance is 4.5 cm since we count out 4 full squares plus half a square when going a horizontal distance from the cement pad to the pool.
Therefore, the distance in real life is 9 meters
1 cm = 2 m
4.5*(1 cm) = 4.5*(2 m)
4.5 cm = 9 m
==========================================
Part (d)
The flowerbed on paper has sides of 4 cm and 6 cm. Use the pythagorean theorem to find the hypotenuse is approximately 7.21 cm.
Double each dimension, and replace the 'cm' with 'm'
The side lengths of the actual flowerbed is 8 meters, 12 meters, 14.42 meters. That last value being approximate.
Add up the values to get the perimeter: 8+12+14.42 = 34.42
Answer: perimeter = 34.42 meters (approximate)
For two odd consecutive numbers, seven times the first number is 1 more than six times the greater number. What is the sum of those numbers?
9514 1404 393
Answer:
28
Step-by-step explanation:
Let x represent the even number between them. Then the desired sum is 2x.
The given relation is ...
7(x -1) = 1 +6(x +1)
x = 14 . . . . . . . add 7-6x
2x = 28 = sum of those numbers

Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is 3 and the y-intercept is at y = 1.
Answer:
y = 3x + b
Step-by-step explanation:
Essentially the question is asking us to find the equation of the line in slope intercept form
Slope intercept form: y = mx + b
Where m = slope and y = y intercept
First let's find the slope
Slope = change in y over change in x
Looking at the line as y goes up 3 x goes up 1
hence slope (m) = 3/1 or just 3
Now let's find the y intercept
The y intercept is equal to the y value of the point where the line passes the y axis
The line passes the y axis at ( 0 , 1 ) and the y value of that point is 1
Hence, y intercept (.b ) = 1
Finally we substitute 3 for m and 1.for b in y = mx + b to get the equation of the line
We get y = 3x + 1.
What is the result when the number 82 is decreased by 8.6%? Round your answer to the nearest tenth.
Answer:
74.948
Step-by-step explanation:
Have a nice day
Answer:
74.948
Step-by-step explanation:
To decrease a number by a percentage, we can simply multiply the number by the reciprocal of the decrease.
To decrease 82 by 8.6 % , we can simply multiply 82 by 91.4%……..
82 x .914= 74.948
Rounded to nearest tenth……..74.9

24) IN A PARALLELOGRAM OPPOSITE ANGLES ARE EQUAL
3y + 2 = 62
3y = 62 - 2
3y = 60
y = 60/3
y = 20°
ALSO IN A PARALLELOGRAM ADJACENT SIDES SUM IS 180°
62 + 5x + 3 = 180°
5x + 65 = 180
5x = 180 - 65
5x = 115
x = 115/5
x = 23°
so option c is correct
.
.
.
25) IN A PARALLELOGRAM THE SIDES OF SAME DIAGONAL ARE EQUAL
5x - 4 = 10x - 24
5x - 10x = -24 + 4
-5x = -20
x = 20/5
x = 4
4x + 14 = 3y + 9
4(4) + 14 = 3y + 9
16 + 14 = 3y + 9
30 = 3y + 9
3y = 30 - 9
3y = 21
y = 21/3
y = 7
.
.
.
so option b is correct

The instruction booklet for a DVD
player says that the player uses about
0.4 kilowatt of electricity per hour. If
electricity costs $0.20 per kilowatt hour,
how much does it cost to run the player
for an hour?
Answer:
$.08
Step-by-step explanation:
it takes 0.4 per hour and it costs $0.20 per hour so you multiply the two numbers together.
0.4 x 0.20 = $.08
1. Shaded area is 14 cm. Find r to the nearest 0.01 cm.
Answer:
Step-by-step explanation:
Area of the quarter circle = 1/4 pi * r^2
Area of the quarter circle = 1/4 * 3.14 * r^2
Area of the triangle = 1/2 r * r = 1/2 r^2
Equation of Solution
1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2 Subtract 1/2 r^2 from both sides
0.785 r^2 - 0.5 r^2 = 14 cm^2 Combine the left
0.285 r^2 = 14. cm^2 Divide by 0.285
r^2 = 14/0.285
r^2 = 49.1228 Take the square root of both sides
sqrt(r^2) = sqrt(49.1228)
r = 7.01
What is the volume of the cylinder shown? Use 3.14 for pi. 4cm is the radius and 9cm is the height.
Answer:
The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04
Step-by-step explanation:
Answer:
Volume - 452.16 cm
Step-by-step explanation:
First we need to find the area of the circle.
Area of a circle - (3.14)r^2
Insert the radius in the formula -
(3.14) (4)^2
3.14 x 16
50.24 is the area of the circle
Now, we have to multiply this value by the height of the cylinder in order to find the volume.
50.24 x 9 = 452.16 cm

1. Two dice are thrown at the same time . What is the probability that the sum will be 7 or 11 ?
2. A ball is drawn at random from a box containing 6 red balls , 4 white balls and 5 blue balls.
Determine the probability that is red or white.
Answer:
1. 0.2222222
2. .6667
Step-by-step explanation:
for question 1
there can only be 36 outcomes so you find out how many time you could get 7and2 which is 8 from so u write 8.36=.2222
for question 2
divide the outcome by the total out comes example(there are 6 red balls and 4 white out of 15 so you do 10/15=.6667)
Answer:
#1Outcomes with sum of 7:
1 + 6, 2 + 5, 3 + 4, 4 +3. 5 + 2, 6 + 1Outcomes with sum of 11:
5 + 6, 6 + 5Total outcomes:
6*6 = 36Required probability:
P(sum of 7 or 11) = (6 + 2)/36 = 8/36 = 2/9 or 22.22%#2P(red or white) = (6 + 4)/(6 + 4 + 5) = 10/15 = 2/3 or 66.67%
