Given an angle t that corresponds to the point (- 3 squared/2, 1/2) on the unit circle show
below, find cos(t) and sin(t).

Answers

Answer 1

Answer:

Step-by-step explanation:

Your question asks what is  -[tex]3^{2}[/tex] / 2    but,  since it's on the Unit circle, I know you meant   - [tex]\sqrt{3}[/tex] /2    Also, it's one of those known angles on the unit circle.

note that the angles can all be put in the form of  [tex]\sqrt{x}[/tex] / 2 , where x = 0,1,2,3,4 ,  for the five special points on the unit circle.  

as the attached pic shows,   Cos(t) for the given point would be 180-150°= 30 and sin(t) would be 90 - 30 = 60 °

it's not easy to understand how I got those angles,  just ask if you don't get it.  :)

X axis or y axis

Answers

Answer:

X-Axis

Step-by-step explanation:

The Y changed from negative to positive meaning that it reflected across the X-Axis

(っ◔◡◔)っ ♥ Hope It Helps ♥

Answer:

x axis

Step-by-step explanation:

Since the x value stayed the same and the y value changed, we can tell that the point was reflected over the x axis.

Another way to think of it:

If you draw a graph and put both points on the graph, try to fold the paper on one of the axis's. Whichever fold causes the two points to touch, is the axis that point D was reflected on.

Estimate a 20% tip on a dinner bill of $142.74 by first rounding the bill amount to the nearest ten dollars.
Estimated tip:
X

?

Answers

$142.74 rounded to nearest ten dollars is $140. And so now you find 20% of 140 by multiplying 140 by .20 (which is the decimal form of 20%). You’ll get $28 and that will be tip but total bill would be $140+$28 or $142.74+$28 to be exact.

Answer:$171.29

Step-by-step explanation:

if the tip amount is around $28.55 and your putting 20% it would $171.29 but it would determine how many people they are.

Triangle ABC is similar to triangle FED, find the measure of x. A. X = 9 B. X = 11 C. X = 110 D. X = 231

Answers

Answer:

[tex]A+B+C=130[/tex]

[tex]F+E+D=273[/tex]

Step-by-step explanation:

From the question we are told that:

Dimension of ABC

A=9

B=11

C=110

Dimension of FED

D=231

Generally the equation for the similar triangles is mathematically given by

[tex]\frac{A}{F}=\frac{B}{E}=\frac{C}{D}[/tex]

Therefore solving for F

[tex]\frac{9}{F}=\frac{110}{231}[/tex]

[tex]F=\frac{9*231}{110}[/tex]

[tex]F=18.9[/tex]

Therefore solving for E

[tex]\frac{11}{E}=\frac{110}{231}[/tex]

[tex]E=\frac{11*231}{110}[/tex]

[tex]E=23.1[/tex]

Measure of [tex]\triangle ABC[/tex]

[tex]A+B+C=130[/tex]

Measure of [tex]\triangle FED[/tex]

[tex]F+E+D=273[/tex]

It wants me to find m∠2 from this

Answers

Answer:

Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°

Step-by-step explanation:

Answer:

90°

Step-by-step explanation:

This is a kite.

The angle measures of the diagonals (the lines in the middle) are always going to be 90° if they looks like this without any other measures. This goes for all other quadrilaterals as well.

m∠2=90°

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Equations are,

y = x + 5

y = - (x + 5)

y = |x + 5|

Since, All equations shows equation of line.

Hence, We can draw all the equations as shown in figure.

y = x + 5

Slope = 1

y - intercept = 5

y = - x - 5

Slope = - 1

y - intercept = - 5

Thus, The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.

I believe it would be 470 cm.

For the blue figure, there are two 2 by 2 panels and three 7 by 2 panels that would be exposed to the surface

So (7•2)•3 = 42 and (2•2)•2 = 8 so 42•8=50

The green panel is made up of four 12 by 7 panels and two 7 by 7 panels, with one of them being covered with a 14 cm part.

So (7•12)•4 = 336 and 7•7 = 49. The top part would be 49-14=35 so 336 + 49 + 35 = 420

And 420 + 50 = 470

Priscilla received 240 votes in the election for student council president. That was 60% of the students who voted in the election. How many students voted in the election? *

Answers

Answer:

400 students voted in the election

Step-by-step explanation:

Given:

Total number of votes received by Priscilla = 240

This was 60% of the students who voted in the election.

To find: Total number of students who voted in the election

Solution:

Total number of votes received by Priscilla = 60% of Total number of students who voted in the election

240 = 60% of Total number of students who voted in the election

240 = [tex]\frac{60}{100}[/tex] × Total number of students who voted in the election

So,

Total number of students who voted in the election [tex]=\frac{240(100)}{60}=400[/tex]
