Answer:
The volume is 180 cube cm.
Step-by-step explanation:
By the given diagram,
The composite figure is made by the two cuboids,
First having dimensions, 2 cm × 5 cm × 6 cm,
And second having dimensions, 8 cm × 5 cm × 3 cm,
So, the volume of the given composite figure = the volume of first cuboid + the volume of second cuboid
= 2 × 5 × 6 + 8 × 5 × 3,
= 60 + 120
= 180 cube cm
The volume of the composite space figure to the nearest whole number is: 180 cube cm.
Here, we have,
from the given information, we get,
By the given diagram,
The composite figure is made by the two cuboids,
First having dimensions, 2 cm × 5 cm × 6 cm,
And second having dimensions, 8 cm × 5 cm × 3 cm,
So, the volume of the given composite figure
= the volume of first cuboid + the volume of second cuboid
= 2 × 5 × 6 + 8 × 5 × 3,
= 60 + 120
= 180 cube cm
Hence, the volume of the composite space figure to the nearest whole number is: 180 cube cm.

Answers

AD = sqrt(2)
A'D' = sqrt(2)
Answer: The co-ordinates of the image quadrilateral areA'(-3, -1), B'(-5, -4), C'(-7, -2) and D'(-4, 0). The length of the segments AD and A'D' are both √2 units.
Step-by-step explanation: We are given to list the co-ordinates of the image after a rotation of the figure below of 180° about the origin.
From the figure, we note that
the co-ordinates of the vertices of quadrilateral ABCD are A(3, 1), B(5, 4), C(7, 2) and D(4, 0).
We know that
the co-ordinates of the image of a point (x, y) after rotation of 180° about the origin is given by (-x, -y).
Therefore, after rotating the quadrilateral ABCD through an angle of 180° about the origin, then the co-ordinates of the image A'B'C'D' are
A(3, 1) ⇒ A'(-3, -1),
B(5, 4) ⇒ B'(-5, -4),
C(7, 2) ⇒ C'(-7, -2)
and
D(4, 0) ⇒ D'(-4, 0).
And, the lengths of the line segments AD and A'D' can be calculated using distance formula as follows :
[tex]AD=\sqrt{(4-3)^2+(0-1)^2}=\sqrt{1+1}=\sqrt{2}~\textup{units},\\\\A'D'=\sqrt{(-4+3)^2+(0+1)^2}=\sqrt{1+1}=\sqrt 2~\textup{units}.[/tex]
Thus, the co-ordinates of the image quadrilateral are A'(-3, -1), B'(-5, -4), C'(-7, -2) and D'(-4, 0). The length of the segments AD and A'D' are both √2 units.

In words: if two numbers multiply to 0, then one (or both) of the values must be zero.
So in terms of algebra, if we had
-0.2*(x-1.9)*(x-3.5) = 0
then
x-1.9 = 0 or x-3.5 = 0
Now solve each individual equation for x
x-1.9 = 0
x-1.9+1.9 = 0+1.9 ... adding 1.9 to both sides
x = 1.9
x-3.5 = 0
x-3.5+3.5 = 0+3.5 .... adding 3.5 to both sides
x = 3.5
The two solutions are x = 1.9 or x = 3.5
These two x values, when plugged into f(x), will make f(x) = 0
These are the x intercepts because this is where the graph crosses the x axis.
Note: "root" is another term for "x intercept"
A ball is thrown into the air from the edge of a 48 foot cliff so that it eventually lands on the ground. The graph below shows the height, y, of the ball from the ground after x seconds.
For which interval is the ball’s height always decreasing?
A. 48
B.0
C.2.5
D.146
Answers
2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.
What is time interval?" Time interval is the division of time into small equal intervals to have a proper observation of any data."
According to the given graph,
x represents time in seconds along x-axis
y represents height in foot of the ball along y-axis
As per observation,
Height of the ball increasing from 48 to 146 in the time interval
0< x < 2.5.
Height of the ball decreasing from 146 to 0 in the time interval 2.5< x < 5.5.
Hence, we conclude that 2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.

A ball is thrown straight up with a initial velocity of 56 feet per second . The height , h , of the ball t seconds after it is thrown is given by the formula h(t)=56t-16t^2 . What is the maximum height of the ball?
Answers
Formula: H(t) = 56t – 16t^2
H(t) = - 16t^2 + 56t
A. What is the height of the ball after 1 second? H (1) = 56(1) – 16(1) ^2 = 40 pt.
B. What is the maximum height? X = - (56)/2(- 16) = 1.75 sec h (1.75) = 56(1.75) – 16(1.75) ^2 h (1.75) = 49ft.
C. After how many seconds will it return to the ground? – 16t^2 + 56t = 0 - 8t =0 t = 0
- 8t (2 + - 7) = 0 2t – 7 = 0 t = 7/2 Ans: 3.5 seconds
The maximum height achieved by the ball is 49 meters at time t = 7/4 seconds.
What is time dependent function?
The time dependent function is the function whose values vary with change in time. For example - f(t) = 3t + 5.
Given is a ball is thrown straight up with a initial velocity of 56 ft/s. The height (h) , of the ball (t) seconds after it is thrown is given by the formula h(t) = 56t - 16t²
The given function is -
h[t] = 56t - 16t²
Now, for maximum height -
dh/dt = 0
d/dt ( 56t - 16t²) = 0
d/dt (56t) - d/dt (16t²) = 0
56 - 16 d/dt (t²) = 0
56 - 16 x 2t = 0
56 = 32t
t = 56/32
t = 7/4 seconds
Now, at t = 7/4 seconds, the height is maximum. Substituting the value
t = 7/4 seconds, we get -
h(7/4) = 56 x 7/4 - 16 x 49/16
h(7/4) = 14 x 7 - 49
h(7/4) = 98 - 49
h(7/4) = 49 meters
Therefore, the maximum height achieved by the ball is 49 meters at time t = 7/4 seconds.

There are three consecutive odd integers. Three times the largest is seven times the smallest. What are the integers?
Answers
This is how I would map out this problem...
First I would represent the smallest integer with the variable x. Since they are consecutive odd integers, add 2 to the middle integer and add 4 to the largest.
smallest: x
middle: x+2
largest: x+4
Now we need to find a way to solve for x. Since 3 times the largest is 7 times the smallest, we can set up an equation like this...
3(x+4)=7x
Now solve it!
3(x+4)=7x
3x+12=7x
12=4x
x=3
Now let's go back to our original data...
smallest: x
•Since the smallest is x, that means the smallest is going to be 3.
middle: x+2
•since the middle one is x+2, plug in 3 for x and we get 5.
largest: x+4
•since the largest is x+4, plug in 3 for x and we get 7.
This means the answer is...
Smallest: 3
Middle: 5
Largest: 7

The time it takes runners to complete a certain marathon are normally distributed with a mean of 4.6 hours and a standard deviation of 1.1 hours what is the time for a runner with a score of -1.2? Round to the nearest hundredth
Answers
The equation for the z-score is
z-Score = (Time - Mean) / Standard Deviation
Given:
mean = 4.6 hours
standard deviation = 1.1 hours
z-Score = -1.2
∴ -1.2 = (x - 4.6) / 1.1
x - 4.6 = -1.32
x = 3.28 hours
The time would be 3.28 hours for a z-score of -1.2.
Explanation:
The formula for a z-score is
z = (X-μ)/σ,
where μ is the mean and σ is the standard deviation.
For our problem, we know that z = -1.2, μ = 4.6 and σ = 1.1:
-1.2 = (X-4.6)/1.1
Multiply both sides by 1.1:
-1.2(1.1) = ((X-4.6)/1.1)*1.1
-1.32 = X-4.6
Add 4.6 to both sides:
-1.32+4.6 = X-4.6+4.6
3.28 = X

Two competing cable companies have recently restructured their payment plans. Clear TV requires a $30 activation fee and charges $75 per month for their basic plan. Link TV requires no activation fee and charges $82.50 per month for their basic plan. When will the two plans be equal in cost?
Answers
Activation fee = $30
Monthly charge = $7
Link TV:
Activation fee = $0
Monthly Charge = $82.50
Let x be the number of month that the two cost will be equal
30 + 75x = 82.5x
82.5x - 75x = 30
7.5x = 30
x = 30 ÷ 7.5 = 4 months
The two plans will be of equal cost after 4 months.

One angle of atriangle measures 12 degrees. the second angle's measurements is five times the third. what is the measure of the third angle
Answers
The measure of the third angle is; 28 degrees.
How does an angle form?An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints.
The point of their joint is called vertex of that angle.
Those two line segments forming it are called arms of that angle.
The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.
Let the third angle be x
Given that One angle of a triangle measures 12 degrees. the second angle's measurements is five times the third.
We know that in a triangle the angles add up to 180 degrees.
so, 12 + 5x + x = 180.
Then we get
6x =168
x =28 degrees.
