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
Answer:
weight of legs - 7 ounces
weight of wings - 4 ounces
Step-by-step explanation:
Let the weight of a chicken leg be represented by l
Let the weight of a chicken wing be represented by w
The total weight of Mr. Nguyen's package can be represented by this equation :
4l + 6w = 52
The total weight of Ms. Dawen's package can be represented by this equation :
3l + 6w = 45
To find the weight of the legs and wing, use simultaneous equation
4l + 6w = 52 eqn 1
3l + 6w = 45 eqn 2
Subtract equation 2 from 1
l = 7 ounces
Substitute for l in equation 1
4(7) + 6w = 52
28 + 6w = 52
Solve for w
w = 4 ounces
Answer:
if the question is 2xy²(23x²y³) then the answer is 46x³y^5
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
because it is a outlier we can assume these 2 things:
it influences the mean and median, with the mean being effected more
because we know this, we can now solve the problem
both the median and mean decreased, but the mean decreased more than the median
I = Prt
I = ($19,200)(12%)(5)
I = $11,520
The boat would cost $11,520 in 5 years.
