Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not? No, the range value 3 corresponds to two domain values, 1 and 2. ... No, there is no value in the domain that corresponds to more than one value of the range. Jun 13, 2017
Step-by-step explanation: The answer is either letter B or letter D.
Determine if the relation is a function.
The relation is a function.
Answer:
D
Step-by-step explanation:
We say a relation between two sets is a function if every value in the first set (the domain) corresponds to exactly one value in the second (the range). This doesn't mean we can't have two different domain values pointing to the same range value, but it does mean we can't have on domain value pointing to two different range values.
Our relation here is a function, since each domain value only points to one range value, so our answer is D.

Answer:
She paid $610.43
Step-by-step explanation:
multiply the original price by the decimal form of the percentage:
⇒ $789.90 x .25 (25%) = $197.475
subtract the product from the original price:
⇒ $789.90 - $179.475 = $610.425
round to the nearest hundreth:
⇒ $610.425 = $610.43
help me please I don’t understand
Answer:
32.87°
Step-by-step explanation:
It is asking for the measure of angle B.
[tex]tanB=\frac{opposite}{adjacent}[/tex]
[tex]tanB=\frac{4.2}{6.5}[/tex]
Now you need to find the arctan because you want the angle. (make sure your calculator is in degree mode)
B= arctan(4.2/6.5)
angle B= 32.86867893°
Find the largest perfect square that divides 350584416
The largest perfect square that divides 350584416 is 58430736
The number is given as: 350584416
Express the number as the product of its factors
350584416 = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 7 x 7 x 7 x 7 x 13 x 13
Express the numbers as exponents
350584416 = 2^5 * 3^3 * 7^4 * 13^2
Rewrite the product as:
350584416 = 2^4 *2 * 3^2 * 3 * 7^4 * 13^2
Reorder the factors
350584416 = 2^4 * 3^2 * 7^4 * 13^2 * 2 * 3
Express the product as a product of a perfect square
350584416 = (2^2 * 3 * 7^2 * 13)^2 * 2 * 3
Write out the perfect square (k)
k = (2^2 * 3 * 7^2 * 13)^2
Evaluate the product
k = (7644)^2
Evaluate the exponent
k = 58430736
Hence, the largest perfect square that divides 350584416 is 58430736

how can tell if a table values is proportional
Answer:
You can
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them.
Answer:
To tell if a table values are proportional, the x and the y value should have a common factor. When the numbers are all divided by their common factor, the points should all be equal to each other.
Ms. Rogers bought 4 bags of candies to make gift boxes for her family. Each bag contained 18 candies. She put an equal number of these candies into each of 7 gift boxes. How many candies were left over?
Answer:
2 candies were left.
Step-by-step explanation:
Number of bags of candies = 4 bags
Number of candies in each bag = 18 candies
Total number of candies = [tex]4(18)=72[/tex]
Ms. Rogers put an equal number of these candies into each of 7 gift boxes.
Divide 72 by 7
72 = 7(10) + 2
Here, remainder is 2.
So,
2 candies were left.

What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² - 7x + 12 = 0
On simplifying , we get
x² - 3x - 4x + 12 = 0
On factorizing , we get
x ( x - 3 ) - 4 ( x - 3 ) = 0
Taking the common factors in the equation , we get
( x - 4 ) ( x - 3 ) = 0
So , the two values of x are
x = 4 and x = 3
Hence , the quadratic equation is solved
