Find the answer to each trigonometric function below. ​
Airida [17]

Answer:

  • Sin A = \frac{opposite}{hypotenuse} =\frac{32}{40} =\frac{4(8)}{5(8)} =\frac{4}{5}
  • Cos C = \frac{adjacent}{hypotenuse} =\frac{16}{34}=\frac{2(8)}{2(17)} =\frac{8}{17}
  • Tan A = \frac{opposite}{adjacent} =\frac{21}{20}

A solar collector is 2,0 m long by 1,5 m wide. It is held in place
icang [17]

Answer:

The width of the frame is 0.0746 meters

Step-by-step explanation:

We are told that after the frame has been attached to the solar collector, the area that is left exposed is 2.5m^2  . As we see in the figure, the dimensions of this area are

(w-2x) and  (l-2x)

where x is the width of the frame.

The product of these dimensions must equal the exposed area:

(w-2x)(l-2x)=2.5m^2

Now since w=1.5m and l=2m we have:

(1.5-2x)(2-2x)=2.5

we expand this and solve for x using the quadratic formula:

4x^2-7x+3=2.5

4x^2-7x+0.5=0

we get two solutions:

x=1.6753

x=0.0746

We take the second solution i.e x=0.0746, because first one gives a width larger than the dimensions of the solar collector which cannot be possible.

Thus the width of the frame is 0.0746 meters.

Order least to greatest 52%, 0.57, and 2/5
Inessa [10]
Simple...

change them all into decimals...or fractions..or percents:

52%, 0.57, \frac{2}{5}--->>

52%--->>0.52

0.57--->>0.57

\frac{2}{5}-->>0.4

Now you can order from least to greatest....

\frac{2}{5}, 52%, 0.57

Thus, your answer.
