Answer the question below
Answer:
The answer is, B / 93.75 square feet
Step-by-step explanation:
Base on of trapezoid = 12.5 ft
Base two iss 0.5 times the length of base one.
Base two = (12.5 x 0.5) ft = 6.25 ft
height = 10 ft
Area of trapezoid ground = 1/2 (sum of the kengths of the parallel sides) x height
= 1/2 (12.5 + 6.25) x 10
= 1/2 x 18.75 x 10
= 93.75 square feet

Use the function f(x) to answer the questions:
f(x) = 5x2 + 2x − 3
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
A) x-intercepts are (0.6, 0) and (-1, 0)
B) vertex is (-0.2, -3.2)
C) see attached
Step-by-step explanation:
Part A
Given function: [tex]f(x)=5x^2+2x-3[/tex]
The x-intercepts are when f(x) = 0
[tex]\implies 5x^2+2x-3=0[/tex]
To factor, find two numbers that multiply to -15 and sum to 2: 5 and -3
Rewrite the middle term of the quadratic as the sum of these number:
[tex]\implies 5x^2+5x-3x-3=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 5x(x+1)-3(x+1)=0[/tex]
Factor out the common term [tex](x+1)[/tex]:
[tex]\implies (5x-3)(x+1)=0[/tex]
[tex]\implies (5x-3)=0\implies x=\dfrac35=0.6[/tex]
[tex]\implies (x+1)=0 \implies x=-1[/tex]
Therefore, the x-intercepts are (0.6, 0) and (-1, 0)
Part B
As the leading coefficient of the quadratic is positive, the parabola will open upwards. This means that the vertex will be a minimum point.
The x-coordinate of the vertex is the midpoint of the zeros.
[tex]\sf midpoint=\dfrac{-1+0.6}{2}=-0.2[/tex]
To find the y-coordinate of the vertex, substitute the found value of x into the given equation:
[tex]f(-0.2)=5(-0.2)^2+2(-0.2)-3=-3.2[/tex]
Therefore, the vertex is (-0.2, -3.2)
Part C
Plot the zeros and the vertex.
The axis of symmetry is the x value of the vertex, so ensure that the graph is symmetrical about x = -0.2.

First, what is volume?
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface. For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contain
FIRST ONE IS UNDERLINED
Now, lets answer.
Volume = lwh
Surface Area = 2(lw + lh + wh)
So, whats the answer?
Area of the floor is 693 sq ft
--------------Steps--------------
The formula for the area of a rectangle is:
A=l×w
The formula for the volume for a rectangular cube is:
V=l×w×h
We can substitute:
2079ft 3 for V
3ft for h
A for l×w
And then solve for A to find the area of the floor: v=l×w×h becomes:
2079ft 3=A×3ft
Therefore,Area of the floor is 693 sq ft

The probability of rolling two number cubes whose numbers match is 6/36
Where does the number 36 come from?
Explain your thinking.
Answer:
The 36 is the total number of choices possible. Two cubes are rolled. If a 1 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). If a 2 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). After doing this for all 6 numbers on the first cube, you find that there are 6+6+6+6+6+6 or 6*6 possible choices. 6*6 is 36, so that is where the 36 is from. You can also use the Fundamental Counting Principle.

pls help quick. A teacher surveys a random group of students about their preference for doing classwork online or on paper. The results are shown in the table below. Based on the results, how many students out of 350 will most likely have a preference to do their class work online?
Results:
Online: 17
Paper: 8
The number of students those who will most likely have their preference to do their classwork online is 238 out of 350
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
According to the question statement:
A teacher surveys a random group of students about their preference for doing classwork online or on paper.
17 preferred online and 8 preferred on paper.
To find the number of students who will most likely have their preference to do their classwork online:
We will apply the concept of probability.
Probability(Event) = Favorable Outcomes/Total Outcomes
For the survey,
probability of students preferring online mode of classwork is = 17 /(17+8)
= 17/25
= 0.68
Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68
Let m be the number of students preferring online mode of classwork.
m / 350 = 17/25
m / 350 = 0.68
m = 350 x 0.68
m = 238
Therefore, the number of students are 238.

For one side of the pyramid:
Since there are two symmetrical triangles on one side of the pyramid, calculate both together as a rectangle.
7x10 = 70cm
There are four equal sides to the pyramid, so multiply the area of one side by 4.
70x4 = 280cm
Finally, calculate the area of the base and add it to the total.
14x14 = 196cm
196+280 = 476cm
Nicole has the cards shown below. All cards are the same size and shape. She put the cards into a bag. Nicole will pull one card out of the bag without looking.
Nicole will perform this experiment a total of 96 times, replacing the card after each pull. What is the total number of times she should expect to pull out a card with an odd number on it?
A.
24 times
B.
32 times
C.
48 times
D.
64 times
Using a Ratio to solve
If we have a ratio of 7/12 odd cards to total cards she can expect to pull out 7 odds in her 12 cards. Now we will use this ratio out of 96 cards. If we have 96 cards with a 7/12 ratio we will divide 96 by 12 which is 8. Now we use our 8 and will multiply it by 7 which is our odd cards. Our total number of odds pulled out of 96 cards will be 56 out of 96.

You make a cylindrical glass with an open top in industrial technology class. What is the surface area of the outside of the glass? Round your answer to the nearest hundredth, if necessary.
Answer:
4247.4 cm^2 after rounding to the nearest tenth
or 4247.43 cm^2 after rounding to the nearest hundredth
Step-by-step explanation:
the surface area can be split into 3 parts, the top, bottom, and side
the top and bottom areas are pretty easy, it's just the area of a circle
A = pi*13^2, which is 169pi for one circle, or 338pi for two
now, imagine the middle being unwrapped into a rectangle. the height of this rectangle is 39cm, and the length is just the circumference of the top/bottom circle, which is 2*pi*13, or 26pi cm
area is base*height, so 1014pi
add the two parts up (1014pi+338pi) to get 1352 pi, or about 4247.433
round to the nearest tenth to get 4247.4 cm^2
round to the nearest hundreth to get 4247.43 cm^2
A rectangle is 4.5 centimeters wide and 6 centimeters long. Calculate the perimeter of the rectangle, in millimeters.
270 millimeters
1.05 millimeters
210 millimeters
105 millimeters
Answer:
210 millimeters
Step-by-step explanation:
There are 10 millimeters in every centimeter.
Width of 4.5cm x 10 = 45 millimeters
Length of 6cm x 10 = 60 millimeters
To figure perimeter, you add all 4 sides.
60 + 60 + 45 + 45 = 210
Perimeter of rectangle = 210 millimeters
The correct option is C.
What is rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral.
Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.
Given,
Length of rectangle = 6 cm
Width of rectangle = 4.5 cm
Perimeter of rectangle = 2(length + width)
= 2(6 + 4.5)
= 2(10.5)
= 21 cm
1 cm = 10 mm
Perimeter of rectangle = 210mm
Hence, 210 millimeters is the perimeter of the rectangle.
