Determine whether each relation is a function.
Answer:
no
Step-by-step explanation:
no
one input (x) has 2 outputs (y)
the input 2 has 2 outputs 1 and 4
this does not pass the vertical line test
therefore it is not a function

One positive integer is 5 less than another. The
product of the two integers is 14. What are the
integers?
Answer:
one is 2 and another is 7
Step-by-step explanation:
let n be the positive integer and n' be the greater integer.
Given condition
n+5=n' ......eqn i
n×n'=14
n(n+5)=14. [from equation i]
n²+5n-14=0
n²+7n-2n-14=0
(n-2)(n+7)=0
either. or
n=2. n=-7(impossible)
therefore n=2 and hence n'=n+5=7.

A complex number will, in general, have _____ fourth complex roots.
Answer:
A complex number will, in general, have five(5) fourth complex roots.
Step-by-step explanation:
We know that the nth complex roots of unity are graphically represented on a unit circle such that there are a total of n roots located at a distance by an angle of
Hence, here we are asked to find the number of complex roots of fifth complex roots.
i.e. n=5

Find the standard equation of the circle with center (5, -3
and with a point on the circle (-3,3)
Answer:
○ C
Explanation:
Accourding to one of the circle equations, [tex]\displaystyle (x - h)^2 + (y - k)^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle (h, k).[/tex]Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:
Pythagorean Theorem
[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = r^2 \hookrightarrow 36 + 64 = r^2 \hookrightarrow \sqrt{100} = \sqrt{r^2} \\ \\ \boxed{10 = r}[/tex]
Sinse we are dealing with length, we only desire the NON-NEGATIVE root.
Distanse Equation
[tex] \displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d \\ \\ \sqrt{[-5 - 3]^2 + [3 + 3]^2} = r \hookrightarrow \sqrt{[-8]^2 + 6^2} = r \hookrightarrow \sqrt{64 + 36} = r; \sqrt{100} = r \\ \\ \boxed{10 = r}[/tex]
Sinse we are dealing with distanse, we only desire the NON-NEGATIVE root.

The fox observed that the tortoise plodded along at a rate of 20 meters per minute throughout the 1000-meter race.
1. Complete the table below indicating the distance traveled by the tortoise in the time elapsed.
The values that are required to complete the table above indicating the distance traveled by the tortoise in the time elapsed are calculated below.
How to calculate the distance traveled?Mathematically, the distance traveled by the tortoise would be calculated by using this formula:
Distance = speed (rate) × time
When time = 1 min, we have:
D₁ = 20 × 1
D₁ = 20 meters.
When time = 2 min, we have:
D₂ = 20 × 2
D₂ = 40 meters.
When time = 3 min, we have:
D₃ = 20 × 3
D₃ = 60 meters.
When time = 4 min, we have:
D₄ = 20 × 4
D₄ = 80 meters.
When time = 5 min, we have:
D₅ = 20 × 5
D₅ = 100 meters.
When time = 6 min, we have:
D₆ = 20 × 6
D₆ = 120 meters.
When time = 7 min, we have:
D₇ = 20 × 7
D₇ = 140 meters.
When time = 10 min, we have:
D₁₀ = 20 × 10
D₁₀ = 200 meters.
When time = 15 min, we have:
D₁₅ = 20 × 15
D₁₅ = 300 meters.
When time = 20 min, we have:
D₂₀ = 20 × 20
D₂₀ = 400 meters.
When time = 25 min, we have:
D₂₅ = 20 × 25
D₂₅ = 500 meters.
When time = 30 min, we have:
D₃₀ = 20 × 30
D₃₀ = 600 meters.
When time = 35 min, we have:
D₃₅ = 20 × 35
D₃₅ = 700 meters.
When time = 40 min, we have:
D₄₀ = 20 × 40
D₄₀ = 800 meters.
When time = 50 min, we have:
D₅₀ = 20 × 50
D₅₀ = 1,000 meters.

A function f is odd and f(x)=x^2 for all x>0. Sketch the graph of of this function and then write the rule of the function as a single formula
Pls solve I put 77 points ito this
The odd function is:
f(x) = sgn(x)*x^2
And the graph can be seen at the end.
How to get the formula of the function?
An odd function has the property:
f(-x) = -f(x).
In this case, for x > 0 we have:
f(x) = x^2
Notice that if we evaluate that in a negative number, we get:
f(-2) = (-2)^2 = 2^2 = f(2)
So, this is actually even.
To transform it into an odd function, we can multiply it by the sign function:
f(x) = sgn(x)*x^2
Now, when x is negative, the outcome will be negative, so the function is odd. The graph can be seen below.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The measure of the ∠B=29.5°.
What is Sine rule?The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]
where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
Given that sides a=10, b=5 and the measure of the ∠A=100°. Therefore, the using the sine law,

O 18

Hey there!
4 + 10(5 - 3) = 4 + 62
4 + 10(5) + 10(-3) = 4 + 62
4 + 50 - 30 = 4 + 62
54 - 30 = 4 + 62
24 = 4 + 62
24 = 66
24 ≠ 66
OR
4 + 10(5 - 3) = 4 + 62
4 + 10(2) = 4 + 62
4 + 20 = 4 + 62
24 = 4 + 62
24 = 66
24 ≠ 66
Thus, this statement is FALSE because both of your numbers aren’t equivalent to each other.
But, let’s try this method
4 + 10(5 - 3) = 4 + 62
4 + 10(2) = 4 + 62
4 + 20 = 4 + 62
24 = 66
24 ≠ 66
66 - 24 = 42
Thus, if this is what your question is asking it would be: Option B. 42

The others are all false for one reason or another
b is false. The factor is made up of 2 terms not 3. 7a is one term.
c is false. "a" is a variable. So the whole term can be anything.

Answer + Step-by-step explanation:
let x be the age of Kevin
y be the age of his mother
a) We can convert the statement “the sum of their ages is 61” into the equation: x + y = 61
b) the coordinates of the intersection point are (15 , 46)
Interpretation:
The age of Kevin is 15
The age of Kevin’s mother is 46
Step-by-step explanation:
Let,
x = Kevin's agey = Kevin's mother's ageGiven that,
Kevin's age + Mother's age = 61
x + y = 61 [tex]\rightarrow[/tex] required equation for a)
[tex]\rule{150pt}{2pt}[/tex]
Now, we have two equations.
y - 3x = 1 -------(1)
y + x = 61 --------(2)
On solving them (using the substitution method),
[tex]\left. \begin{cases} { y-3x = 1 } \\ { y+x=61 } \end{cases} \right.[/tex]
Take ----(1)
[tex]y-3x=1 \\y=3x+1[/tex]
Now, substitute the value of y in ----(2)
[tex]y + x = 61\\3x+1+x=61 \\4x+1=61 \\4x=60 \\x = 15[/tex]
Substitute the value of x in -----(1),
[tex]y=3\times 15+1 \\y= 45+1\\y = 46[/tex]
So,
[tex]\boxed{\bf\:x = 15, \:y = 46}[/tex]
Now, by graphing them (see the attachment), the point of intersection is O (15, 46). Hence, from this we can infer that, Kevin is 15 years old while his mother is 46 years old. [tex]\rightarrow[/tex] answer for b)

Answer:
6 inches
Step-by-step explanation:
Solving
Curved Area = π x r x slant height66 = 3.14 x 7 x rr = 66/21.98 ≅ 3 inchesWidth of the hat
Diameter of the cone2 x Radius2 x 3 = 6 inchesAnswer:
6.00 in (nearest hundredth)
Step-by-step explanation:
Lateral surface area = surface area excluding the bases(s)
Lateral surface area of a cone = [tex]\pi rs[/tex]
(where r is the radius and s is the slant height)
Given:
lateral surface area ≈ 66 in²slant height (s) = 7 in[tex]\implies 66= \pi r \cdot 7=7 \pi r[/tex]
[tex]\implies r=\dfrac{66}{7 \pi}[/tex]
The width of the hat is the diameter. As diameter = 2r:
