Answer:ellipse
Step-by-step explanation:
The term which describes the set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant is Ellipse.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Conic sections are the two dimensional curves which are obtained by the intersection of the cone with the plane.
The four conic sections are ellipse, parabola, hyperbola and circle.
A circle has all the points equidistant from the center.
Ellipse is a one such plane where the curve includes the set of points for which the sum of the distances to two fixed points equals a certain constant which is called the focus.
Hence the correct option is ellipse.

Linda is building steps for her porch. What is the volume of the steps?
144,000 cm3
288,000 cm3
324,000 cm3
540,000 cm3
Answer:
Step-by-step explanation:
upper block:
length (l) = 120 cm
Width (w) = 30 cm
Height (h) = 60 cm
Volume of upper block = l * w * h
= 120 * 30 *60
= 216,000 cm³
Lower Block
l = 120 cm
w = 30 cm
h = 30 cm
Volume of lower block = 120 * 30 * 30
= 108,000 cm³
Volume of steps = 216,000 + 108,000 = 324,000 cm³

4(1 - x) + 3x = - 2(x + 1)
Answer:
X=-6
Step-by-step explanation:
4(1−x)+3x=−2(x+1)
(4)(1)+(4)(−x)+3x=(−2)(x)+(−2)(1)(Distribute)
4+−4x+3x=−2x+−2
(−4x+3x)+(4)=−2x−2(Combine Like Terms)
−x+4=−2x−2
−x+4=−2x−2
Step 2: Add 2x to both sides.
−x+4+2x=−2x−2+2x
x+4=−2
Step 3: Subtract 4 from both sides.
x+4−4=−2−4
x=−6
Answer:
x=−6

Find the volume of the rectangular prism.
length = 5 1/4 inches
Width = 2 1/2 inches
Height = 2 inches
Answer:
Step-by-step explanation:
length = 5 1/4 = 21/4 inches
Width = 2 1/2 = 5/2 inches
Height = 2 inches
Volume of rectangular prism = length * width * height
[tex]= \frac{21}{4}*\frac{5}{2}*2\\\\= \frac{21}{4}*5\\\\=\frac{105}{4}[/tex]
= 26.25 cubic inches

In 2005 a house was purchased for $280,000 and
in 2013 it was sold at $334,000. Assuming that
the value of the house increased at a constant
annual rate what will be the price of the house in
the year 2018?
Given that in 2005 a house was purchases for 280,000 and was later sold in 2013 for 334,000, determine the increase value of the house and what the price of the house will be in 2018.
First, we subtract the two values of the house on both dates.
334,000 - 280,000 = 54,000
Then, divide the difference by the amount of years from 2005 to 2013.
54,000/8 = 6,750
Since, it says the value increases at a constant rate, this indicates that it is a linear function.
So, the linear function would start at 280,000 as the y-intercept and the slope is 6,750.
Linear Function: y = 6750x + 280,000
Lastly, to find the price of the house in 2018, we just need to plug in 13 for x since x represents the years.
y = 6750x + 280,000
Plug in 13 for x.
y = 6750(13) + 280,000
y = 87750 + 280,000
y = 367,750
Thus, the value of the house in 2018 is $367,750.

can sales found in newspapers or online be referred to as offers?
Answer:
Yes
Step-by-step explanation:
Only if its sold by a person and not a company, most people refer to that as an offer.
Answer:
Yup, it can
Step-by-step explanation:
In newspapers or online people do many offers/sales to get you to buy something. For example, let's say you see Gardening Services, that would be considered as an offer, because the salesperson or company is selling you something. Online, you could be sold offers as well, like a new phone, a house, etc.

An orange juice can has a diameter of 4 inches and a height of 7 inches. The curved surface of the can is painted orange. How much paint is needed? Round your answer to the nearest tenth.
Answer: 88 in2
Step-by-step explanation:
The side of the can, which when "unrolled" is a rectangle, with width = height of the cylinder (7 in); and length = Circumference = 2π radius
Surface area of the curved surface of the can = 2π (diameter/2) x height
Replacing with the values given:
S = 2π (4/2) x 7 = 2π (2) x 7 = 88 in2
