The ryan family pays 1,347 per month for rent. If their rent doesn't change, how much will they pay in dollars for rent over 30 years
Answer: 4,84,920
Step-by-step explanation:
Given
The rent per month is 1347
for a year it is 12 months
for 30 years it is [tex]30\times 12=360\ \text{months}[/tex]
Rent for 30 years it is
[tex]\Rightarrow \text{rent}=1347\times 360=484,920[/tex]
The bids in an online auction are represented by the arithmetic sequence shown below. Write an explicit formula to represent the bids as an arithmetic sequence. What is the bid?
207,216,225,234
Answer:
aₙ = 207+9*(n-1)
Step-by-step explanation:
a1 = 207+9*(1-1) = 207
a2 = 207+9*(2-1) = 216
a3 = 207+9*(3-1) = 225
....
aₙ = 207+9*(n-1)

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17 units
Step-by-step explanation:
Moving from (-8, 0) to (7, 8), we see x changing by 15 units from -8 to 7 and y changing by 8 units from 0 to 8.
Regard 15 units as the horizontal leg of a right triangle and 8 units as the vertical leg. We use the Pythagorean Theorem to determine the length of the hypotenuse of this right triangle and interpret the result as the distance between the points:
d = √(15² + 8²) = √289 = 17
The distance between the given points is 17 units.

Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?
y=−13(x+5)^2−4
y=−13(x−5)^2+4
y=13(x−5)^2−4
y=13(x+5)^2−4
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4
what is the x-intercept of y=2x-1
Answer::::::::::

Write the slope intercept equation for this table
Answer:
y = 2x -4
Step-by-step explanation:
y2 - y1 / x2 - x1
-4 - (-6)/ 0 - (-1)
= 2
y = mx + b
y = -2x + b
-4 = -2(0) + b
-4 = 0 + b
-4 = b
So the equation is y = 2x -4
The total surface area of a cube is 294cm^2.
Work out the volume of the cube.
Answer:
343 cm ^3
Step-by-step explanation:
A cube has 6 squares of equal sizes. 294/6 = 49
The area of one square is 49
Since the area is the length squared, the square root of 49 is 7.
Volume of a cube is area times height. 49 x 7 = 343 cm^3
