Use the circle unit to find sin 90 degrees
kati45 [8]

Answer:

Sin 90°=1

Step-by-step explanation:

A unit circle is a circle with a radius of 1 .Because the radius is 1, it is possible to directly measure the sine, cosine and tangent.

<em>using the unit circle where 90° is the limit as the hypotenuse approaches the vertical y-axis which is positive.</em>

Sine=opposite/hypotenuse

Sin=O/H

<u>Applying the limits</u>

Sine 90°=1/1= 1

cos 90° =0/1 =0

or

When the angle formed at the origin of the unit circle in the 1st quadrant is 0°, cos 0°=1 sin0°=0  and tan 0°=0

When we increase the angle until it is 90°, cos 90°=0, sin 90°=1 and tan 90°=undefined

When Lisa started at her current job, her employer gave her 2 days of paid
Novay_Z [31]

a. The equation computed shows that the number of paid vacation days has she earned will be 17 days.

b. The time when she will reach the maximum number of paid vacation days allowed is 6 years.

<h3>How to compute the equation?</h3>

a. The equation computed shows that the number of paid vacation days has she earned will be:

= 2 + 3x

x = 5

= 2 + 3(5)

= 2 + 15

= 17 days.

b. The maximum number of days for a pod vacation will be:

= 4 × 5

= 20 days.

The time when she will reach the maximum number of paid vacation days allowed will be:

20 = 3x + 2

3x = 20 - 2.

3x = 18

x = 18/3

x = 6 years

Please help fast! I'm being timed. <br> What is the value of x?
Naddika [18.5K]

That's Intersecting Secants, and we get


EC × ED = EB × EA


(x+4)(x+4+1) = (x+1)(x+1+11)


(x+4)(x+5) = (x+1)(x+12)


x^2 + 9x + 20 = x^2 + 13x + 12


8 = 4 x


x = 2


Check: 3(14)=42 6(7)=42 good


Answer: 2

bazaltina [42]
Ok, here we go.
The x-value is given(Great!), so now we need to find y-value for slope
\frac{2347-465}{3000}
\frac{1882}{3000}
The average slope, according to the calculator, is 0.627
