Answer:
39 feet
Step-by-step explanation:
take the tree as AB , the distance between the man and the tree as BC, the distance between the man and the tip of the shadow CD and the point intersecting the hypotenuse CE
since CE parallel to AB we can BPT
CE/AB = CD/BD
6/32= CD/48
CD = 9 feet
since CD is feet
BC is 48-9 = 39 feet
Answer:
I thinks it’s 7x + 5
Step-by-step explanation:
For each curve, plug in the given point
and check if the equality holds. For example:
(I) (2, 3) does lie on
since 2^2 + 2*3 - 3^2 = 4 + 6 - 9 = 1.
For part (a), compute the derivative
, and evaluate it for the given point
. This is the slope of the tangent line at the point. For example:
(I) The derivative is

so the slope of the tangent at (2, 3) is

and its equation is then

For part (b), recall that normal lines are perpendicular to tangent lines, so their slopes are negative reciprocals of the slopes of the tangents,
. For example:
(I) The tangent has slope 7/4, so the normal has slope -4/7. Then the normal line has equation

Answer:
Total number of people = 13
A:
Number of ways to choose 10 players to take the field = 13C10
= 
= 286
B:
This is given as: 13P10
=
= 
= 1037836800
C:
This is given as:
(3C1 x 10C9) + (3C2 x 10C8) + (3C3 x 10C7)
Solving this we get the answer as = 285
Answer:
Its A and C. Since you need a reflection then a dilation to result in that image.
