Answer:
Statement 1 - false
A function is one-to-one or many-to-one.
One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)
Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.
The true statement should be:
The relation is a function because some y-values correspond to more than one x-value.
Statement 2- true
The domain is the set of input values (x-values). Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.
Statement 3 - true
The range is the set of output values (y-values). Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

what is the difference between the greatest and least amounts of rain falls? Iready
Answer:
[tex]1\frac{7}{8}inches[/tex]
Step-by-step explanation:
From the image we know that the greatest amount of rainfall is 2 inches, and the least is 1/8. If we subtract these two, we'll find the difference
[tex]2-\frac{1}{8} =\frac{16-1}{8} =\frac{15}{8} =1\frac{7}{8}[/tex]
Therefore, the difference between the greatest and least amount of rainfall is [tex]1\frac{7}{8}inches[/tex]
Remember that the greatest amount of rainfall is represented by the greatest number, and the least amount of rainfall is represented by the least number.
Which of the following is a geometric series? 40 50 60 70 40 42 44 46 40 80 40 120 40 20 10 5
The given series 40 + 20 + 10 + 5 is a geometric series.
What is the geometric series?The geometric series the ratio of consecutive terms is equal and the ratio is called the common ratio of the geometric series.
Let us find the ratio of consecutive terms of each of the given series.
For the series 40 + 50 + 60 + 70
50/40 = 5/4
60/50 = 6/5
Since, 5/4 ≠ 6/5 hence, it is not a geometric series.
For the series 40 + 42 + 44 + 46
42/40 = 21/10
44/42 = 22/21
Since, 21/10 ≠ 22/21 hence, it is not a geometric series.
For the series 40 + 80 + 40 + 120
80/40 = 2
40/80 = 1/2
Since, 2 ≠ 1/2 hence, it is not a geometric series.
For the series 40 + 20 + 10 + 5
20/40 = 1/2
10/20 = 1/2
Since, 1/2 = 1/2 hence, it is a geometric series.
Therefore, D is the correct option.

Answer:
40π m² and 125.6 m²
Step-by-step explanation:
the area (A) of the sidewalk is calculated as
A = outer area - inner area
(a)
A = πr₁² - πr₂² ( r₁ is radius of outer circle and r₂ the radius of inner circle )
A = π × 11² - π × 9²
= 121π - 81π
= 40π m²
(b)
A = 40 × 3.14 = 125.6 m²
When simplified and written in standard form, which quadratic function is equivalent to the polynomial shown? 2 7c – 4c2 – 3c 4 –4c2 4c 6 –7c2 10c 6 –4c2 4c 8 –7c2 7c 6
The simplified and standard form of the considered polynomial is -4c^2 -4c + 6
What is standard form of a polynomial?Suppose the considered polynomial is of only one variable.
Then, the standard form of that polynomial is the one in which all the terms with higher exponents are written on left side to those which have lower exponents.
The given polynomial is:
[tex]2 + 7c - 4c^2 - 3c + 4[/tex]
Simplifying it gives:
[tex]2 + 7c - 4c^2 - 3c + 4 = 2+4 + (7-3)c - 4c^2 = 6 -4c -4c^2[/tex]
Writing it in the order of increasing to decreasing powers:
[tex]6 -4c -4c^2 = -4c^2 -4c + 6[/tex]
Thus, the simplified and standard form of the considered polynomial is [tex]-4c^2 -4c + 6[/tex]

work out 9 over 13 of 182 (9 over 13 is supposed to be a fraction)
Answer:
126
Step-by-step explanation:
In math, "of" usually means multiplication.
9/13 of 182 means 9/13 × 182.
9/13 × 182 = 9/13 × 182/1 = (9 × 182)/(13 × 1) = 1638/13 = 126
Answer: 126
Answer:
126
Step-by-step explanation:
To find 9/13 of 182, we would divide 182 by 13 and multiply the quotient by 9.
182 ÷ 13 = 14
14 • 9 = 126
To double-check our answer, we can divide 126 by 182 and see if the fraction is congruent to 9/13.
126 ÷ 182 = 0.6923
9 ÷ 13 = 0.6923

Step-by-step explanation:
[tex]y-5=\frac{1}{4} (x-8)[/tex]
[tex]y=\frac{1}{4} x-2+5[/tex]
[tex]y=\frac{1}{4} x+3[/tex]
Hope this helps
Answer:
y = [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = [tex]\frac{1}{4}[/tex] , then
y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
to find c substitute (8, 5 ) into the partial equation
5 = 2 + c ⇒ c = 5 - 2 = 3
y = [tex]\frac{1}{4}[/tex] x + 3 ← equation of line
