pls help me with this multiple choice !

Answer:

Step-by-step explanation:  sin β = [tex]\frac{oposite }{hypotenuse}[/tex] ; cos β = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

10) sin [tex]32^{0}[/tex] = [tex]\frac{x}{18}[/tex]

18 sin [tex]32^{0}[/tex] = x

18 (0.53) = x

x= 9.5 units

cos [tex]32^{0}[/tex] = [tex]\frac{y}{18}[/tex]

18 cos [tex]32^{0}[/tex] = y

y = 18 (0.85)

y = 15.3 units

Answer:

  C.  y = 2x - 3

Step-by-step explanation:

The y-intercept (b) can be found from ...

  y = mx + b

  y - mx = b . . . . . subtract mx

Here, you are given (x, y) = (-1, -5) and slope m = 2.

  b = -5 -2(-1) = -5+2 = -3

The correct equation is ...

  y = 2x -3 . . . . . matches choice C

_____

On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

Answer:

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Answer:

Step-by-step explanation:

5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5

(27/5)/(9/10) = 27/5 * 10/9

cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2

= 3/1 * 2/1 = 6/1 = 6

Answer:

The angles are supplementary.  

Step-by-step explanation:

Both angles lie on a straight line.  When two angles are right next to each other on a straight line, then they add up to 180...therefore they are supplementary.

Hope this helps!! :D

Answer:

the third option, C (6,0)

Step-by-step explanation

B is 3x, and 6y. Since C is still on the bottom of X, it doesn't have any number for y. Although, it is far to the right which gives it 6x.

Answer:

4x - 8 + 4y

Step-by-step explanation:

4(x - 2 + y)

4x - 8 + 4y

You multiply each term in the parenthesis by the number in front of it.

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

Answer:

Step-by-step explanation:

4x + 6 + 3x + 21 = 8x + 7

7x + 27 = 8x + 7

-x + 27 = 7

-x = -20

x = 20

m<3= 8(20) + 7

         160 + 7 = 167

m<1= 4(20) + 6 = 80 + 6 = 86

m<2= 3(20) + 21 = 60 + 21 = 81

Answer:17

Step-by-step explanation:

trust me its right, no cap

As per compound interest,  it would take 17 years for the value of the account to reach $2,550

If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 -  [tex]e^{rn}[/tex]]

Given, the invested amount (P) = $790.

Rate of interest (r) = 6.9% = 0.069.

Let, the amount is invested for 'n' years.

The value of the amount after 'n' years = $2550.

Now, as per compound interest:

A = P. [tex]e^{rn}[/tex]

⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]

⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)

⇒ [tex]e^{(0.069n)}[/tex] = 3.23

⇒ 0.069n = 1.172

⇒ n = 17

Answer:

AAA (or AA)

Step-by-step explanation:

Prove ΔBEC ~ ΔDEA

(using three angles is unnecessary because you can just use Angle Angle to prove similarity)

First, m∠BCE = m∠EAD because of alternate interior angles.

Then, m∠ADE = m∠CBE  because of alternate interior angles.

m∠BEC = m∠AED because of vertical angles

Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

Answer:

c

Step-by-step explanation:

The line segment OD is congruent to line segment OB. Therefore, option C is the correct answer.

Equal chords of a circle are equidistant from the center of the circle.

From the given figure, AC=EF=9.07.

So, AC and EF are equal chords.

Since, the chords are equal, they are equidistance from center.

Then, OD=OB

Therefore, option C is the correct answer.
