It can't. 9 x 1/4 = 2 and 1/4. The equation in the question is a false statement.
Answer:
7.1
Step-by-step explanation:
Using the distance formula
d = sqrt ( (x2-x1)^2 + ( y2-y1)^2)
sqrt ( (-5-2)^2 + ( -3- -2)^2)
sqrt( ( -7)^2 + ( -3 +2)^2)
sqrt( ( 49 + 1)
sqrt( 50)

Answer:
See below
Step-by-step explanation:
To graph the line we need two points, one point is the y-intercept, the second point to be calculated.
Q7
<u>y = -3x + 6</u>
- The y-intercept is (0, 6)
<u>Let the domain be x = 5 for the second point, then:</u>
- y = -3*5 + 6 = -15 + 6 = -9
- The point is (5, -9)
Connect these points to get the graph
Q8
<u>y = 4/5x - 3</u>
- The y-intercept is (0, -3)
<u>Let the domain be x = 5 for the second point, then:</u>
- y = 4/5*5 - 3 = 4 - 3 = 1
- The point is (5, 1)
Connect these two points to get the graph
To solve this problem, we can use the tan function to find
for the distances covered.
tan θ = o / a
Where,
θ = angle = 90° - angle of depression
o = side opposite to the angle = distance of boat from
lighthouse
a = side adjacent to the angle = height of lighthouse = 200
ft
When the angle of depression is 16°18', the initial distance
from the lighthouse is:
o = 200 tan (90° - 16°18')
o = 683.95 ft
When the angle of depression is 48°51', the final distance
from the lighthouse is:
o = 200 tan (90° - 48°51')
o = 174.78 ft
Therefore the total distance the boat travelled is:
d = 683.95 ft - 174.78 ft
