Answer:

$\cos\ A = \frac{2}{4.5}$

Step-by-step explanation:

Given

$sin\ A = \frac{2}{4.5}$

See attachment

Required

Explain and correct the error

The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.

The ratio can be corrected as by using:

$\cos\ A = \frac{Adjacent}{Hypotenuse}$

$\cos\ A = \frac{AC}{AB}$

$\cos\ A = \frac{2}{4.5}$

At what point on the graph of y=2e^X -1 is the tangent line parallel to the line y= 5x -1

IgorLugansk [536]

Paralell has same slope
y=mx+b
m=slope
y=5x-1
when is the slope 5?

take the derivitive of 2e^x
f'(2e^x)=2f'(e^x)=2e^x

that is the slope
5=2e^x
divide both sides by 2
2.5=e^x
take the ln of both sides
ln2.5=x

when x=ln2.5 they are paralell
