Answer: Choice C (lower left corner)

==================================================

Explanation:

"one and a half" can be represented by 1.5 because 0.5 = 1/2, so this means that we have 1.5 times \sqrt{x} leading to the function S(x) = 1.5\sqrt{x}

At this point, we have a choice between B and C based on the function we just found. However, we can rule out choice B because the point (0,0) is not on the function curve. Note how plugging in x = 0 leads to

y = 1.5*sqrt(x)

y = 1.5*sqrt(0)

y = 1.5*0

y = 0

So this proves how (x,y) = (0,0) is one point on the function curve. Only choice C fits the description.

The question is not "Which one is correct?" The question is" Why isn't there more than 1 answer."

B

B says the graph is S(x) = 1.5*sqrt(L)

(0,0) should be one of the points. Also for x = 4 for the length

sqrt(4) = 2. 2 * 1.5 = 3. That means something with a sail on it that is 4 feet in length.  B doesn't give 3 as the answer for a 4 foot long boat.

What does C give for x = 4? It gives 3 just as it should. The answer is C

Answer C.

Answer:

20 hours

Step-by-step explanation:

First off, if we divide the number of hours he has played by the number of weeks 15/3 =

It would be an average of <u>5 hours per week</u>

Therefore, in the next 4 weeks we would practice for 20 more hours.

The height of an object from a distance
olga55 [171]
Y = height
x = distance from tower

tan(19.9) = y/x

tan(21.8) = y/(x-50)   ( x is 50 feet closer so subtract 50 from x)

find the tan of the angles:
tan19.9 = 0.362
tan21.8 = 0.400

replace those values in the equations:
0.362 = y /x
0.400 = y / (x-50)

rewrite to solve for height:
0.362x = y
0.400(x-50) = y  distribute the 0.400 and rewrite as 0.400x-20 =y

now solve:

0.362x = 0.400x-20

add 20 to each side:
0.362x +20 = 0.400x

subtract 0.362x from each side:

20 = 0.038x

divide both sides by 0.038
x = 20 / 0.038 = 526.3 feet

now that x is known replace x in the original equation and solve for y:

tan19.9 = y /x

0.362 = y / 526.3
y = 0.362 x 526.3
y = 190.5

the height of the tower is 190.5 feet

When x = 10

f(10) = 10/2 + 8

= 5+8
