Initial value of the painting as per equation y = 1470(1.05)t is equals to 0.
What is equation?
" Equation is defined as the representation of relation between two quantities using symbol of equality."
According to the question,
Given,
Equation of the given models 'y' = 1470(1.05)t
'y' represents the value of painting
't' represents the number of years
Initial year 't' = 0 years
Substitute the value of initial time 't' =0 in the given equation we get,
Initial value of the painting 'y' = 1470 (1.05) (0)
= 0 dollars
Hence, initial value of the painting as per equation y = 1470(1.05)t is equals to 0.

what is 2,457,310 rounded to the nearest thousand
Answer:
2,457
Step-by-step explanation:
The thousands place is when you move four spaces to the left starting from the first number. In this case, that number was seven, and to round, you need to round it up or down depending if the number to the left of the 4th number is greater or less than 5. In this case, that number was 3, so that 3 and the rest of the remaining numbers turn into 0's, making the rounded number 2,457.
I hope this information was of any use to you.

Find the solution to the equation 4r + 2(r - 8) = 4(3 + r).
Answer:
r = 14
Step-by-step explanation:
Use distributive property:
4r + 2r - 16 = 12 + 4r
Combine like terms:
6r - 16 = 12 + 4r
Isolate the variable:
6r = 28 + 4r
2r = 28
r = 14
Answer:
r = 14
Step-by-step explanation:
4r + 2(r - 8) = 4(3 + r)
4r + 2r - 16 = 12 + 4r
6r - 16 = 12 + 4r
6r - 4r - 16 = 12 + 4r - 4r
2r - 16 = 12
2r - 16 + 16 = 12 + 16
2r = 28
2r ÷ 2 = 28 ÷ 2
r = 14
Identify the domain of the function shown in the graph.
O A X20
OBXSO
O c. xis all real numbers.
D-43XSO
Can someone please help me
Answer:
A x >= 0
Step-by-step explanation:
a function is a defined mathematical operation (or a sequence of operations) that uses input values (typically called "x") and calculates the corresponding results (typically called "y").
so, y = f(x)
and (x,y) are then usually the coordinates on the grid.
the domain is the range or interval of numbers the function is using (x) to create results (y).
so, look at the graph !
for what values of x do you see the functional line drawn ?
that means, the functional line goes along only what part of the x-axis ?
I see it starts at x=0 and then continues all the way to the right and clearly further.
for me that means f(x) calculates values for every positive x we can think of. and including 0.
it does not do anything for any negative x-values.
so, clearly answer A (x>=0) is right.

What is the volume of the rectangular prism?
Type the answer in the boxes below.
Answer:
[tex]3\frac{3}{4}\: \mathrm{cm^3}[/tex]
Step-by-step explanation:
The volume of a rectangular prism is given by [tex]V=l\cdot w\cdot h[/tex], where [tex]l[/tex] is the length of the prism, [tex]w[/tex] is the width of the prism, and [tex]h[/tex] is the height of the prism.
The box has a height of 3 boxes, a length of 5 boxes, and a width of 2 boxes. Since each box is 1/2 cm long, we can deduce the prism has a:
Height of 1.5 cmLength of 2.5 cmWidth of 1 cmTherefore, the volume of the prism is

Anyone know the answer? Please and thank you
Answer:
x = 9
Step-by-step explanation:
Given 2 secants from an external point to the circle , then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
3(3 + x) = 4(4 + 5) ← distribute parenthesis on both sides
9 + 3x = 16 + 20 = 36 ( subtract 9 from both sides )
3x = 27 ( divide both sides by 3 )
x = 9
Triangle NOP is similar to triangle QRS. Find the measure of side RS. Round your answer to the nearest tenth.
Answer:
22.1
Step-by-step explanation:
If the triangle is similar then the side lengths have common ratios
*Create ratio to solve for RS*
47.8/13 = RS/6
Now solve for RS
simplify
47/13 = 3.677
We now have 3.677 = RS/6
Multiply each side by 6
3.677 * 6 = 22.1
RS/6 * 6 = RS
we're left with RS = 22.1

A certain number multiplied by five and then two subtracted,
the answer is seventy-seven. Find the number
Answer:
x = 15.8
Step-by-step explanation:
let the number be x
according to the question equation is
x*5 - 2 = 77
5x - 2 = 17
5x = 77 + 2
5x = 79
x = 79/5
x = 15.8
Answer:
5x - 2 = 77
x = 15.8
Step-by-step explanation:
a number - x
times 5 - 5x
minus 2 - 5x - 2
equals 77 - 5x - 2 = 77
77 + 2 = 79
79 ÷ 5 = 15.8
5(15.8) - 2 = 77

Which functions have a range of ..
Answer:
Options (3) and (5)
Step-by-step explanation:
Option (1)
f(x) = x² + 7x - 2
= x² + 2(3.5)x + (3.5)² - (3.5)² - 2
= (x + 3.5)² - 14.25
Therefore, vertex of the graph → (-3.5, -14.25)
And the graph will open upwards.
Range of the function → [-14.25, ∞)
Option (2)
f(x) = -(x + 1)² - 4
Since, leading coefficient is negative, curve of the function will open downwards.
Vertex → (-1, -4)
Range of the function → [-4, -∞)
Option (3)
f(x) = -4x + 11
This function is defined for all real values of x.
Range of the function → (-∞, ∞)
Option (4)
f(x) = [tex]2^{x+3}[/tex]
Range of this exponential function → (0, ∞)
Option (5)
f(x) = [tex]\frac{2}{3}x-8[/tex]
Function is defined for all real values of x.
Range of the function will be (-∞, ∞)
Therefore, Options (3) and (5) are the correct options.

An indoor track is made up of a rectangular region with two semi-circles at the ends. The distance
around the track is 400 meters. Determine the radius of the semicircular ends of the track in terms of y.
Answer:
r = (200 - y)/π
Step-by-step explanation:
The question details includes;
The shape of the indoor track = Two semi-circular ends and a mid rectangular region
The distance around the indoor track = 400 meters
The radius, r, of the semicircular ends in terms of y = Required
Let y represent the length of the rectangular middle area of the track, we have;
The perimeter of the indoor track = The distance around the track = 400 m
The perimeter of the indoor track = 2 × π·r + 2 × y = 400
2 × (π·r + y) = 400
∴ π·r + y = 400/2 = 200
r = (200 - y)/π
