If a = 20 mm, b = 12 mm, and m∠C = 80°, what is the approximate area of ABC?
Lana71 [14]

Answer:

118.18 mm^2

Step-by-step explanation:

Sides <em>a</em> and <em>b</em> form angle C, so the information given is a side-angle-side (SAS) problem.

Use the formula A=\frac{1}{2}ab\sin{C}.

A=\frac{1}{2}(12)(20)\sin{80^\circ} \approx 118.18 \rm \,mm^2

What is the ratio of 3 and 5
-Dominant- [34]

Answer:

in regards to ratios, think of fractions. If we have a ratio of 3:5, that means that in fraction form we can think of it as

3

---

5

If put this into a calculator (3 divided by 5), you will get a decimal of 0.6 as the answer. This means that any two numbers that divide and come to the same answer are equivalent to 3/5.

Now, from what it appears you are asking, they want you to find two other numbers that come to the same ratio / answer of 0.6, and that these numbers should be double. To do this, simply multiply the numerator and denominator by 2, which is double.

3 x 2 = 6

5 x 2 = 10

So our fraction now is

6

---

10

If you put that into a calculator (6 divided by 10), it will come to the same answer of 0.6. Therefore, this fraction / ratio is equivalent to the original.

If your answer is expected to be in ratio format, then it should be 6:10

Which of the following represents a function
Oksana_A [137]

Answer:

(2,3),(4,3),(-2,-3),(-4,-3)

Step-by-step explanation:

A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).

This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.

The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.

A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.

In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:

(5,1),(5,2),(5,3),(5,4)

Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.
