Answer:
75 units²
Step-by-step explanation:
PL² = 6² + 8²
PL² = 100
PL = 10
Triangles PAL and MPL are similar triangles
6/8 = PM/10
PM = 10 × 6/8 = 7.5
Area = 7.5 × 10
75 units²
Answer:
1.08 is the constant of proportionality.
Step-by-step explanation:
The constant value (often written k) relating amounts that rise or fall uniformly together.
It is the ratio of the amounts y and x:
k = y/x
Put another way: y = kx
Example: you are paid $20 an hour
The constant of proportionality is 20 because: Pay = 20 × Hours worked
Question:<u /> <em>Simplify the trigonometric expression sec</em><span><em>Өcos</em></span><span><em>Ө.</em></span>
For each of the three basic trig functions, (sin, cos, tan) there are three more which act as their reciprocals. (csc, sec, and cot respectively)
Reciprocals, of course, are flipped fractions. If you have some number x, the reciprocal can be expressed as

.
An important property of reciprocals is that if you mutliply them together they will cancel out--take

for example.
Since sec
