How to round the number 3.987 to the nearest tenths

Harman [31]

First you go the tenths place which is the number 9 stands. You look to the left of the number. Here is the tricky part if the number is under 5 for example 1 2 3 4. The number stays the same and everything behind that number is 0. If the number is 5 or higher the number goes up one and everything behind it is 0. So 3.987 rounded to the nearest tenth is 4.000

Find the area of a trapezoid with base lengths 3 and 5 and heigh of 9

Likurg_2 [28]

A <u>trapezoid</u> is a quadrilateral with exactly one pair of parallel sides.

Formula for area: $A = \frac{1}{2}(^{b}1 + ^{b}2)(h)$

In this formula, the bases are the parallel sides.

Now plug the information into the formula.

$A = \frac{1}{2} (3 + 5)(9)$ .

Follow your order of operations, simplify inside the parentheses first.

$A = \frac{1}{2}(8)(9)$ .

(1/2)(8) is 4 so we have (4)(9) which is 36.

So the area of the trapezoid is 36.

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.
