Answer:
distance TS ≈ 19 m (nearest meter)
Step-by-step explanation:
The point T is on the horizontal ground and the angle of elevation of the top R of a tower is 63° and the height of the tower is 38 m high. The illustration forms a right angle triangle. The height RS of the tower is the opposite side of the triangle formed. The hypotenuse side of the triangle is the point from the ground T to the top of the tower R. The adjacent side of the triangle is the side TS.
using tangential ratio
tan 63° = opposite/adjacent
tan 63° = 38/adjacent
cross multiply
adjacent tan 63° = 38
divide both sides by tan 63°
adjacent side = 38/tan 63°
adjacent side = 38/1.96261050551
adjacent side = 19.3619670807
distance TS ≈ 19 m (nearest meter)
The contractor would have to work for 20 hours on the site to earn $555 total pay
What is total cost function?
Total cost function is the sum of the fixed charge, which is fixed cost to the person paying the contractor when the contractor visits the site and charge per hour multiplied by the number of hours spent working
TC=a+bX
TC=total cost=$555
a=fixed charged=$55
b=charge per hour=variable element of contractor's pay=$25
X=number of hours spent working=unknown
$555=$55+$25X
$555-$55=$25X
$500=$25*X
X=$500/$25
X=20
The contractor needs to work for 20 hours in order to earn a total pay of $555

Answer:
LCM stands for Least Common Multiple
To calculate LCM you need to divide the no.s given by smallest divisor going to the greatest until the no.s can be divided no more
Answer:
Yes is a pythagorean triple
Step-by-step explanation:
To know if you can build a right triangle with those sides we have to make the following equality
h² = l1² + l2²
The hypotenuse is always the longest side so it should be 30
we check the equality of the equation
30² = 18² + 24²
900 = 324 + 576
900 = 900
Equality was fulfilled so it is a right triangle
Answer:
The value of the parameter of interest in this setting is:
d. The value of the parameter of interest cannot be determined from the given information.
Step-by-step explanation:
To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina. We also require the population proportion of these streams, which have runoff from hog farms. But in this situation, the information is lacking. Instead, we are given information about the sample, which only produces statistics. For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.
