I'm having trouble figuring out what the equation is for the trend line and what the slope is
Talja [164]

Answer:

The equation for the trend line would be y = -1/100x + 25

Step-by-step explanation:

In order to find the trend line, we first need to find the slope. To do so, we need to find two points on the line. The points we'll use are (0, 25) and (2500, 0). Next, we use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (0 - 25)/(2500 - 5)

m = -25/2500

m = -1/100

Now that we have this we can use the slope and the intercept in slope intercept form to model the trend line.

y = mx + b

y = -1/100x + 25

Sin 7A = cos 3A, then m∠A is what?
lbvjy [14]

Answer:

m∠A = 9°

Step-by-step explanation:

\sin 7A =  \cos 3A \\  \\ \sin 7A =  \sin(90 \degree -  3A) \\  \\ 7A =  90 \degree -  3A\\  \\ 7A  + 3A=  90 \degree  \\  \\ 10A=  90 \degree  \\  \\ A =  \frac{90 \degree}{10}  \\  \\  m \angle A =9 \degree
