Which expression represents the volume of the composite figure? (2)(4.4)(5) (2)(4.4)(3.9) (2)(4.4)(5) – (2)(4.4)(3.9) one-half(2)(4.4)(5) – one-third (one-half)(2)(4.4)(3.9) one-half(2)(4.4)(5) one-third (one-half)(2)(4.4)(3.9)
The expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)
What will be the volume of the composite figure?The volume of the composite figure will be the sum of the volume of the prism and the volume of the pyramid.
The Volume of the prism = Area of the base * height of the prism
Area of the base = 1/2*4.4 *2
Height of the prism =5
So, the Volume of the prism = (1/2)* (4.4)*(2)*(5)
The volume of the pyramid = 1/3 *(area of the base) * (height of the pyramid)
Area of the base of the pyramid = 1/2*4.4 *2
Height of the pyramid =3.9
So, the volume of the pyramid = (1/3)* (1/2)*(4.4)*(2)*(3.9)
So, total volume = (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)
Hence, the expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

The volume of any shape is the amount of space in it.
The volume of the cylinder is 1570 square units
How to determine the volume?The question is incomplete. Assume the following parameters
Shape = Cylinder
Radius, r = 10
Height, h = 5.
The volume of a cylinder is:
V = πr^2h
So, we have:
V = 3.14 * 10^2 * 5
Evaluate the product
V = 1570
Using the assumed values, the volume of the cylinder is 1570 square units

The points on the red arc are points A and B
The measure of the red arc is 75 degrees
How to determine the measure of arc XYZ?From the complete question, we have:
Angle DCE = 75 degrees
By vertical angles theorem,
Angle ACB = Angle DCE = 75 degrees
So, we have:
Angle ACB = 75 degrees
The measure of the red arc is the same as the measure of the angle ACB.
So, we have:
Red arc = 75 degrees

5+4+9+2+4=24Matilda and her family took a trip to Yellowstone National Park to see Old Faithful
erupt. Matilda was standing 125ft from the blast. The blast rose 100ft in the air.
What is the angle from Matilda to the top of the blast?
Using the slope concept, it is found that the angle from Matilda to the top of the blast was of 38.66º.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem, the vertical change is of 100 ft, while the horizontal change is of 125 ft, hence:
[tex]\tan{\alpha} = \frac{100}{125}[/tex]
[tex]\alpha = \arctan{\left(\frac{100}{125}\right)}[/tex]
[tex]\alpha = 38.66^\circ[/tex]

A college professor wants to survey a sample of students taking his course. Here are some details about his course:
He teaches 5 sections of the course.
There are 250 total students across those sections.
There are 50 graduate students and 200 undergraduate students taking the course.
Each section has about 50 students (some graduate and some undergraduate).
The professor wants to take a sample of 30 students for a survey. He suspects that opinions on the survey may differ the most based on student type (graduate or undergraduate), so he wants to design his sample to take that into account. Which of these strategies will accomplish his intended design?
a. Randomly select 6 students from each section for the survey.
b. Randomly select 6 graduate students and 24 undergraduate students for the survey
c. For each section, randomly select one of the first 8 students to arrive to class, and every 8th student thereafter to take the survey.
d. Randomly select one of the sections and give the survey to every student in that section
Answer: B, Randomly select 6 graduate students and 24 undergrad students for the survey.
Step-by-step explanation: This guarantees that each type is proportionately represented in the survey.
Not A because it risks too many or too few graduate students. It is not C because again, it risks too many or too few graduate students. It is not D because each section has about 50 students and the professor only wants 30 in his sample.

The depth of the water at the end of a pier changes periodically along with the movement of tides. on a particular day, low tides occur at 12:00 a.m. and 3:30 p.m., with a depth of 3.25 meters, while high tides occur at 7:45 a.m. and 11:15 p.m., with a depth of 8.75 meters. which of the following equations models d, the depth of the water in meters, as a function of time, t, in hours? let t = 0 be 12:00 a.m. d = negative 3.75 cosine (startfraction 4 pi over 31 endfraction t) 5 d = negative 3.75 cosine (startfraction 4 pi over 29 endfraction t) 5 d = negative 2.75 cosine (startfraction 4 pi over 31 endfraction t) 6 d = negative 2.75 cosine (startfraction 4 pi over 29 endfraction t) 6
In this exercise we have to calculate the value of the water depth, so we have: d=5.5Cos(12t)+6
What are periodic waves?
A periodic wave is a wave with a repeating continuous pattern that determines its wavelength and frequency
Putting together some information given in the statement we have:
The minimum depth of 3.25 m occurs at 12:00 am and at 3:30 pm.Therefore the period t=0 will be 12:00 am.The maximum depth of 8.75 m occurs at 7:45 am and at 11:15 pm.Knowing that the formula will be given by an equation similar to:
[tex]d=acos(bt)+k[/tex]
Where:
d = depth, mt = time, hoursa= amplitudeThe amplitude difference is given by:
[tex]8.75-3.25=5.5\ m[/tex]
The mean depth is:
[tex]k=\dfrac{(3.25+8.75)}{2}=6\ m[/tex]
Then writing the equation with;
[tex]d=acos(bt)+k\\\\d=5.5cos(12t)+6[/tex]
Hence the value of water depth will be d=5.5Cos(12t)+6

1. w^2+9w+14
2. x^2-14x+45
Answer:
1. ( w + 7 ) ( w + 2 )
2. ( x - 9 ) ( x - 5 )
Step-by-step explanation:
1.
w² + 9w + 14
= w² + 7w + 2w + 14
= w ( w + 7 ) + 2 ( w + 7 )
= ( w + 7 ) ( w + 2 )
Hence, factorised.
2.
x² - 14x + 45
= x² - 5x - 9x + 45
= x ( x - 5 ) - 9 ( x - 5 )
= ( x - 9 ) ( x - 5 )
Hence, factorised.
