To evaluate the expressions, you substitute -9 for x and 3 for y into the expressions
(4y)^2 - (2x)
= (4(3))^2 - (2(-9))
= (12)^2 - (-18)
= 144 + 18
= 162
4y^2 - 2x^2
= 4(3)^2 - 2(-9)^2
= 4(9) - 2(81)
= 36 - 162 = -126

Evaluate the function, find f(-2):
f(x) = 2x^2 +3x
Answer:
B) 2
Step-by-step explanation:
f(-2) = 2 * (-2)^2 + 3(-2)
f(-2) = 2 * 4 - 6
f(-2) = 8 - 6
f(-2) = 2

Which is a better deal 12.4 ounces for $4.99 or 21 ounces for $6.49?
Answer:
Getting 21 ounces for $6.49 is a better deal!
Step-by-step explanation:
4.99 / 12.4 = 0.402419...
6.49 / 21 = 0.30904...
0.4 is larger than 0.30 therefore 0.30 is less and a better deal.

What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
Area of the circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
As per the given circle,
(a)→ Center is at K
(b)→ Radius is at KI
(c)→ Chord is at KL
(d)→ Diameter is at JKI
(e)→ Sectant is at JL
(f)→ Tangent is at GI
(g) →Point of Tangency is at H
(h)→ Minor Arc is at JL
(i)→ Major Arc is at HIJ
(j)→ Semicircle is at HIL
(k)→ Center Angle is at HKI
(l) →Inscribed Angle is at HIJ

Overbooking flights is a common practice of most airlines. A particular airline, believing that 5% of passengers fail to show for flights, overbooks (sells more tickets than there are seats). Suppose that for a particular flight involving a jumbo-jet with 265 seats, the airline sells 278 tickets. Question 1. What is the expected number of ticket holders that will fail to show for the flight
Answer:
The expected number of ticket holders that will fail to show for the flight is 13.9.
Step-by-step explanation:
For each ticket holder, there are only two possible outcomes. Either they fail to show up for the flight, or they do not. Ticket holders are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
5% of passengers fail to show for flights
This means that [tex]p = 0.05[/tex]
278 tickets sold
This means that [tex]n = 278[/tex]
What is the expected number of ticket holders that will fail to show for the flight?
[tex]E(X) = np = 278*0.05 = 13.9[/tex]
The expected number of ticket holders that will fail to show for the flight is 13.9.

You can think of percentages in terms of fractions. Describe how you can think about 10%, 25%, and
75% by using fractions. Consider using tape diagrams to support your explanation
Answer:
You can think percentages as fractions by always using the denominator as 100 and the percentage as the numerator. For example, 10% would be 10/100 or 1/10 and 25% as 25/100 or 1/4 and 75% as 75/100.
dimensions of a rectangular prism as shown below: Length:2 1/4 feet. Width: 1 foot. Height:1 1/4 feet. The lengths of the side of a small cube or 1/4 for each. Part A: how many small cubes can be packed in a rectangular prism? Show your work. Part B: use the answer obtained in part a to find the volume of a rectangular prism in terms of the small cube in unit cube.
Answer:
Step-by-step explanation:
In this case we will use the formula V= length × width × height
so, V= 2 1/4 × 1 × 1 1/4
=2 1/4 × 1 1/4
= 9/4 × 5/4
= 45/16
=2 13/16 cubic feet is the full capacity of the rectangular prism
then get the volume of the cube so, we will use the formula V= side times side times side
so, V= 1/4 times 1/4 times 1/4
V= 1/8 times 1/4
V= 1/32 cubic is the volume of the cube
then we will divide the full capacity of the rectangular prism to the volume of the cube
so, 2 13/16 divided by 1/32
so, 2 13/16 times 32/1
so, 45/16 times 32/1
=1,440/16
=90 small cubes can be packed in a rectangular prism in Part A
so, in Part B
V= 2 1/4 × 1 × 1 1/4
=2 1/4 × 1 1/4
= 9/4 × 5/4
= 45/16
=2 13/16 cubic feet is the volume of the rectangular prism
