First write the equations in the slope-intercept form:
Line 1 passes through the points (-6,-6) and (-4,-3).
Line 2 passes through the points (0,3) and (2,6).
These are two identical lines so the system of equations has infinitely many solutions. The answer is D.
Answer:
a. A = -1 and B = 1
b. A = 7 and B = -5
Step-by-step explanation:
a.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 0
(A + B)x = 0
A + B = 0
A = -B
B - A = 2
B - (-B) = 2
2B = 2
B = 1 and A = -1
b.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 2x
(A + B)x = 2x
A + B = 2
A = 2 - B
2A + 3B = -1
2*(2-B) + 3B = -1
4 - 2B + 3B = -1
B = -5 and A = 2 - (-5) = 7
Estimate tree height: 50 ft
First, you'd have to get the hypotenuse of the smaller triangle to get the base of the bigger triangle. This can easily be done using Pythagorean theorem (15^2 + 5^2 = hyp^2). The hyp of smaller triangle/base of bigger triangle is 15.81 ft. Then you'd also want to get the angle adjacent to the 5 ft leg, and opposite the 15 ft leg of the smaller triangle to get one of the two remaining angles of the bigger triangle. This can be done via sohcahtoa, using the TOA part. The inverse tangent of opposite/adj leg will give you the angle you're looking for (71.6 deg). With that, you'll know that the remaining angle is 18.4 deg (sum of all angles is 180). You can solve for the height of the tree/hypotenuse of the bigger triangle by using SOH. Sine of 18.4 is equal to 15.81/hypotenuse. Solving for that will give you around 50 ft.
Answer: A2, B3, E1, C5, D4
Step-by-step explanation:
1. A is Maxium because it is the highest point on the graph
2.B is Midline because it is the “middle”
3.C is Peroid because the graph in a way ends or meets back in the middle
4.D is Minimum because it is the lowest point on the graph
5.E is Amplitude
