I believe the equation should be y = -0.5sin(x-2<span>π)-2</span>
Answer:
142.5
Step-by-step explanation:
150/x=100/95
95*150/100=
142.5
Y = e^tanx - 2
To find at which point it crosses x axis we state that y= 0
e^tanx - 2 = 0
e^tanx = 2
tanx = ln 2
tanx = 0.69314
x = 0.6061
to find slope at that point first we need to find first derivative of funtion y.
y' = (e^tanx)*1/cos^2(x)
now we express x = 0.6061 in y' and we get:
y' = k = 2,9599
Function tangent of an angle in a right triangle equals
- opposite side / adjacent side
- sine of the angle / cosine of the angle
For this reason, all answers choices are correct except the fourth one, which is the cotangent of angle PAB.
Answer:
y = -1/2x - 3
Step-by-step explanation:
slope: (y2-y1) / (x2-x1)
(-5 - -2) / (4 - -2)
(-5 + 2) / (4 + 2)
-3 / 6
- 1 / 2
y-intercept: y = mx + b
-5 = -1/2(4) + b
-5 = -2 + b
-3 = b
