Help Me Answer This Trignometry Question. The Final Answer Is Actually Is 18.3 .but I Get Something Else.

Answers

Answer 1

Answer:

y ≈ 18.3

Step-by-step explanation:

Using the sine ratio in the right triangle

sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{y}[/tex] ( multiply both sides by y )

y × sin41° = 12 ( divide both sides by sin41° )

y = [tex]\frac{12}{sin41}[/tex] ≈ 18.3 ( to 1 dec. place )

-x - 163 = 12x + 84

Answers

Answer:

X = -19

Step-by-step explanation:

Add x to both sides to get rid of -x

-163 = 13x + 84

subtract 84 from both sides

-247 = 13x

divide by 13

x = -19

X= - 19 always look for that variable

Answer:

y = -3x -16

Step-by-step explanation:

For problems like this, I like to start with a variation of the point-slope form of the equation of a line:

y = m(x -h) +k . . . . . for a line with slope m through point (h, k)

For your given values, this is ...

y = -3(x +3) -7

y = -3x -9 -7 . . . . eliminate parentheses; next, combine terms

y = -3x -16

Answer:

x = -5 + [tex]\sqrt{26}[/tex]

Step-by-step explanation:

f(x) = x² + 10x - 1

        x² + 10x = 1

        x² + 10x + 25 = 1 + 25

        (x + 5)² = 26

take the square root of each side to get:

        x + 5 = √26

        x = √26 - 5  or -5 + √26

Solve for the value of x in the picture above.

Answers

Answer: C

Step-by-step explanation:

The triangle in the picture is an equilateral triangle. We know this is true because all sides are equal, as denoted by the tick marks. In equilateral triangles, each angle is 60° because when you add all the angles, you get 180°.

4x+8=60        [subtract both sides by 8]

4x=52            [divide both sides by 4]

x=13

Now, we know that C is the correct answer.

I need help on how to solve 8 × 6 + (12 - 4) ÷ 2​

Answers

Answer:

42

Step-by-step explanation:

8x6+(8)/2

48+4

42

Answer:

52

Step-by-step explanation:

So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:

8 × 6 + (12 - 4) ÷ 2​

12 - 4 = 8

Now the equation looks like this:

8 × 6 + 8 ÷ 2

Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first​:

8 * 6 = 48

8/2 = 4

So the equation looks like this:

48 + 4

We now add them together to get our answer:

48 + 4 = 52

So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2​ = 52

Answer:

The points (3, 0) and (0, -3) would be the two solutions.

Hence, options A and D are correct.

Step-by-step explanation:

We know that when the system of equations meets at a point on a coordinate plane, that point or points will be the required set of solutions.

The point where the system of equations meets is called the point of intersection.

If we closely observe, the graph indicates that the graph of two equations meets at the following two points:

at x = 3 and y = 0at x = 0, y = -3

Therefore, the points (3, 0) and (0, -3) would be the two solutions.

Hence, options A and D are correct.

Pythagorean theorem to find the side of 16 20

Answers

Answer: 12

Step-by-step explanation:

Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.

The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse.  Thus, plug in the values to get:

[tex]16^2+b^2=20^2[/tex]

nathan smiled at 50 people one day and recorded that 36 people smiled back at him.Based on his observations how many people should nathan expect to return a smile if he smiles at 650 people over a period of time

Answers

Given :

Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.

To Find :

How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.

Solution :

Ratio of people smiled by total number of people is :

[tex]R = \dfrac{36}{50}[/tex]

Now, it is given that we have to use the given conditions.

Therefore, ratio will be same :

[tex]\dfrac{s}{650}=\dfrac{36}{50}\\\\s = \dfrac{36}{50}\times 650\\\\s = 468[/tex]

Therefore, number of smiles Nathan expect to return is 468.

What is the order, from widest to narrowest graph, of the
quadratic functions f(x) = -0.5x2, f(x) = 1/4x2, and f(x) = x2?

Answers

Answer:

f(x) = [tex]\frac{1}{4}x^{2}[/tex]  > f(x) = -0.5x² > f(x) = x²

Step-by-step explanation:

In a quadratic function leading coefficient decides the width of a graph.

In simpler words, leading coefficient decides the vertical stretch of the graph.

Higher the value of leading coefficient, higher the vertical stretch.

When a graph is vertically stretched it becomes narrower.

(Note: Minus sign of the coefficient decides the opening of the graph, upwards or downwards)

Therefore, f(x) = x² having coefficient = 1 is the narrowest and f(x) = [tex]\frac{1}{4}x^{2}[/tex] will be the widest.

So the descending order will be,

f(x) = [tex]\frac{1}{4}x^{2}[/tex]  > f(x) = -0.5x² > f(x) = x²
