Step-by-step explanation:
Dereck and Sam are standing 3.1 feet apart.
The situation forms two right angle triangle.
<h3>What is a right angle triangle? </h3>
A right angle triangle is a triangle that has one of its angles as 90 degrees.
Derek looks at a 10 foot basketball goal with an angle of elevation of 29°.
Sam looks at the goal with an angle of elevation of 43°.
Sam is directly in front of Dereck. Therefore,
Dereck distance from the base of the basket ball can be found as follows:
tan 29 = opposite / adjacent
opposite side = 10 ft - 5.83 ft = 4.17 ft
tan 29 = 4.17 / x
x = 4.17 / 0.55430905145
x = 7.52287913948
x = 7.523
Sam distance from the base of the basket ball can be found as follows
tan 43 = 4.17 / y
y = 4.17 / 0.93251508613
y = 4.47177752084
y = 4.471
There feet apart = 7.523 - 4.471 = 3.052 = 3.1 feet

Answer:
-2, compliments
Step-by-step explanation:
The computation of the cross elasticity of demand is shown below:
Given that
(P1, Q1) = (7, 25)
(P2, Q2) =(5,50)
Now here we use the mid-point formula for determining the cross price elasticity
= [(Q2 - Q1) ÷ (P2 - P1)} × [(P1 + P2) ÷ (Q1 + Q2)]
= [(50 - 25) ÷ (5 - 7)] × (5 + 7) ÷ [(25 + 50)]
= -2
Hence, the cross-price elasticity is -2
It is negative so these are complementary goods
Hence, the correct answer is -2, compliments
