Ralph the monkey is looking down at a 59° angle from the top of a tree. There are bananas on the ground 12.4 ft from the base of

the tree. If Ralph flies down from the tree at a diagonal path, shown in the diagram by x, what distance would he travel? Round to the nearest hundredth

Answer:

Ralph the monkey traveled 14.47 feet

Step-by-step explanation:

As shown in the picture below we are looking for the value of the hypotenuse which in this case is the diagonal distance Ralph the monkey would travel if he jumped at a 59° degree angle. Since we are given the angle 59° and the opposite side length, we can use the SIN operator to solve this problem.

sin(x) = \frac{opposite}{hypotenuse}

sin(59) = \frac{12.4}{x}

\frac{1}{sin(59)} = \frac{x}{12.4} .....invert both fractions

1.166 = \frac{x}{12.4}

14.47 = x

We get a value of 14.47 ft for the hypotenuse, meaning that Ralph the monkey traveled 14.47 feet after jumping from the top of the tree at a 59° angle.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

This forms a right angled triangle and Ralph flies down the hypotenuse x,

so using trigonometry:-

sin 59 = 12.4 / x

x = 12.4 / sin 59

= 14.47 feet to nearest hundredth.

Write an equation for the line having a slope of -1/3 and y-intercept is 5
amm1812

Answer:

y= -1/3x +5

Step-by-step explanation:

Using the equation y=mx+b

you know <em>m</em> (slope), which is -1/3

you also know your <em>b</em> which is 5

You get y= -1/3x+5

Please help me with this
Mumz [18]

Answer:

x=3/4

Step-by-step explanation:

You need to isolate the variable. First subtract 3 from both side, then add 1x to both sides. You will end up with 1 1/3x=1. After that divide both sides by 1 1/3.

The height, h, of a ball that is tossed into the air is a function of the time, t, it is in the air. The height in feet for t se
Ivenika [448]

Answer:

e) none

Step-by-step explanation:

The first thing that we need to realise is that this question is set to a practical example of a ball being tossed into the air for a period of time. Thus, we know that:

a) time cannot be negative

b) a ball cannot travel a negative distance in height from where it was tossed it into the air (given that this starting position is also the ground)

In the context of what the problem asks us to achieve, which is to find the domain, we now know that:

a) t ≥ 0

b) the function h(t) is only practical when h(t) ≥ 0

In other words, we know that the domain starts at t = 0, however we need to find when the ball drops back onto the ground. We can do this by solving h(t) = 0:

h(t) = -16t^(2) + 96t

0 = -16t^(2) + 96t

0 = -16t(t - 6) (Factorise -16t^(2) + 96t)

So, now we get:

-16t = 0, therefor t = 0

or

t - 6 = 0, therefor t = 6

Thus, the ball is on the ground at t = 0 seconds and t = 6 seconds; it is between these two values of t that the domain exists and that the problem is practical.

Now, looking at the multiple choice options, it seems as though none of them are correct, therefor the answer would be e) none.

The other way to work through this question (particularly if it is just multiple choice) is that, after realising that the ball is tossed into the air at t = 0 seconds and then drops at some point later, we could already discount a), b) and c) as answers since they include infinity in the domain, which is not practical for this problem.

Then, we could substitute t = 5 into the equation to get:

h(t) = -16(5)^2 + 96*5

h(t) = -16*5*5 + 96*5

h(t) = -80*5 + 96*5

Since we need h(t) to be 0 at the end value of the domain, this is not the correct answer. Thus, the answer is e) none.

What is the median value of the data set shown on the line plot?
Mars2501 [29]
Hello!

The median is the number in the middle when the data is ordered from least to greatest

Order the numbers first

1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11

From here when find the medians which are two 6's which means the median is 6

Hope this helps!
