REY [17]

Answer:

B. 14.34

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between the side opposite the angle of interest and the hypotenuse:

Sin = Opposite/Hypotenuse

For the given triangle, this means ...

sin(35°) = b/25

b = 25·sin(35°)

b ≈ 14.34

Which of the following terms best describes the set of all points in a plane for which the difference between the distances of a

Gnoma [55]

Answer:

HYPERBOLA

Step-by-step explanation:

We have the statement,

'The set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant'.

We know that,

Hyperbola is the set of points such that for point P anywhere on the curve, the absolute distance to the two fixed points is a constant.

i.e. From the figure, we see that, the difference of the distance of P from $F_{1}$ and $F_{2}$ is equal to constant 2a.

Thus, the term representing the given statement is HYPERBOLA.

You are a contractor and charge $45 for a site visit plus an additional $24 per hour for each hour you spend working at the site

tino4ka555 [31]

Answer:

Equation: 810= (90 + 24y)

y = 30 hours

Step-by-step explanation:

Given:

Site visit = $45 per site

cost per hour worked = $24

for each work site, the total amount of money earned

= site visit fee + cost for working

But the question mentions TWO sites, hence there will be two site visits. Therefore for TWO sites, we have to account for TWO site visit fee.

Therefore for TWO sites, the total amount of money earned

= site 1 visit fee + site 2 visit fee + cost for working

= (2 x site visit fee) + cost for working ------ Equation 1

We are further given that we worked y hours at the hourly work rate of $24 per hour.

Hence the cost for working

= y hours x hourly rate

= y x $24

= $24y (substituting this into equation 1 above)

for TWO sites, the total amount of money earned

= (2 x site visit fee) + cost for working

= (2 x $45) + $24y

= $90 + $24y

= $(90 + 24y)

We are also given that we have to earn $810 for two sites, hence

810 = 90 + 24y

810 - 90 = 24y

24y = 720

y = 720/24

y = 30 hours
