Answer:
y = 2x + 5
Step-by-step explanation:
First, find the slope using rise over run, (y2 - y1) / (x2 - x1)
With this information, we can create 2 points: (2, 9) and (5, 15)
Plug in the points:
(15 - 9) / (5 - 2)
6 / 3
= 2
Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
15 = 2(5) + b
15 = 10 + b
5 = b
Plug in the slope and b into the equation:
y = 2x + 5 is the equation of the line
B= 5,3
c=4,-1
a=2,1
this is the answer to part c
Answer:
a. 360.323 m
b.
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B = +
=
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
= + - 2ac Cos B
Sot hat;
= + - 2(187 x 308) Cos
But, Cos = 0
So that,
= +
= 34969 + 94864
= 129833
b =
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
=
=
=
Sin A =
= 0.5190
⇒ A = 0.5190
=
The bearing of the plane from its original location = +
=
Answer:
$1361.68
Step-by-step explanation:
15000 > 10000
so she gets the 8.5%
so she gets 108.5% of her salary
x/1255 = 108.5/100
1255(108.5) = 136,167.5
136,167.5/100 = 1361.68
Answer:
X> -6
Step-by-step explanation:
