Which graph represents a function?

Answer:

a) 33.4

b) About 3 students can fit at the end of each row. The triangle formed by the 60° angle has an opposite leg of that is about 7.5 feet longer than the opposite leg formed by the 50° angle. Because each students needs 2 feet of space, 3 more students can fit on each end with about 1.5 feet of space left over.

Step-by-step explanation:

A. I used the Tangent ratio which is opposite/adjacent

tan(50)=x/14

14*tan(50)=x

*Use you calculators here and you should get about 16.68, but this is only one of the right triangle, so multiply that by 2 and you should get about 33.36 which rounded should become 33.4

B. For the amount of students you can fit at the end of each row, you need to find how long the opposite leg of the 60° triangle is than the opposite leg of the 50° triangle. to do this use the tangent ratio

since the 60° triangle is a special triangle, the opposite side is 14√3

14√3 - (14 · tan(50) ≈ 7.56  ← the answer is 7.5 probably since they didn't round (in Big Ideas)

7.56/2 ≈ 3.78 ← 2 feet of space for each student

↑answer is just 3 since you cannot split living objects

The last answer is 1.5

the get the left over amount, we would have to take the length opposite leg of the 60° triangle and divide it by the length of the opposite leg of the 50° triangle

14√3 ÷ (14 · tan(50) ≈ 1.45 ← must use parentheses otherwise they will divide your answer by 14 and then multiply, which none of us wants.

The area of the picture is 68 square inches

Given the following parameters

Area of the frame alone = 72 square inches

Area of the square picture = 2 * 2 = 4 square inches

Determine the area of the picture

Area of the picture = 72 square in - 4 square in

Area of the picture = 68 square inches

Hence the area of the picture is 68 square inches

Solution :-

Hey there!

12 + 5a^2 - (15 - 3a^2)

DISTRIBUTE -1 WITHIN the PARENTHESES

= 12 + 5a^2 - 1(15) - 1(-3a^2)

= 12 + 5a^2 - 15 + 3a^2

COMBINE the LIKE TERMS

= (5a^2 - 3a^2) + (12 - 15)

= 5a^2 + 3a^2 + 12 - 15

= 8a^2 - 3

Therefore, your answer is: 8a^2 - 3

The measure of ∠H is 180 degrees, which is a straight angle.

An angle with a measure of exactly 180 degrees is called a straight angle. It is an angle with arms that point in opposing directions from the vertex and unites to make 180°.

The given measure of ∠H is (11x - 29).

To determine the measure of ∠H when x = 19, we can simply substitute x = 19 into the expression for the measure of ∠H:

∠H = 11x - 29

∠H = 11(19) - 29

∠H = 209 - 29

∠H = 180

Here, ∠H has a measure of 180 degrees, which is a straight angle.

Therefore, the measure of ∠H when x = 19 is 180 degrees.

Answer:

5 1/7

Step-by-step explanation:

Because we first add the whole numbers 3 and 1 which = 4 wholes.

Then 2 + 6=8/7 so since our nominator is more than our demionater we add another whole so now we have 5 wholes and what is left over?

1 since we took away 7 from 8 which is 1/7 so our answer is 5 wholes and 1/7

Let's consider what we are asked. The domain is defined as a set of points that satisfy the equation on the x-ordinate.

So, essentially, we need to find if and what the restriction on x is.

Let's now consider just f(x) because g(x) is completely irrelevant to the question.

f(x) = 2 - x^(1/2)

Since f(x) can never be 0 for a defined function, let's consider when f(x) = 0 to find a restriction on x.

2 - x^(1/2) = 0

2 = x^(1/2)

+-4 = x

But we can only take the positive 4 because inside a square root has to always be positive (unless you're dealing with complex numbers), so the only restriction is that x cannot be equal to 4.
