Answer 2

Step-by-step explanation:

remember the basic trigonometry setup ?

the norm circle (radius = 1) with a horizontal and a vertical line through the center of the circle.

and then there is an angle at the center indicated by the horizontal line and an inclined (by that angle) radius line connecting the center and the circle arc.

this inclined radius line is then the baseline (Hypotenuse) of a right-angled triangle, and the legs of that triangle are sine and cosine of the angle at the center (sine is the vertical leg, cosine is the vertical leg).

in essence (at least it works for me), when given such right-angled triangle problems, I always try to rotate and/or flip this triangle until it looks like the described situation above.

the only other thing to remember is that for triangles inside circles with a different radius than 1, everything is multiplied by the actual radius (it really happens also for the norm circle, but multiplying by 1 does not really change anything, right ?).

so, now for the given problems :

1)

x is the radius of the circle.

we can make 68° the defining angle of that trigonometric situation. so, the top right vertex would be the center of the circle with radius x.

then

30 = cos(68)×x

x = 30/cos(68)

= 80.08401488...

2)

60 is the radius of the circle.

x is the defining angle.

then

15 = sin(x)×60

sin(x) = 15/60 = 1/4

x = 14.47751219...°

3)

x is the radius of the circle.

22° is the defining angle.

then

14 = cos(22)×x

x = 14/cos(22)

= 15.0994864...

4)

the unnamed side is the radius of the circle. let's call it "s".

54° is the defining angle.

then

47 = cos(54)×s

x = sin(54)×s

x/47 = sin(54)×s / (cos(54)×s) = sin(54)/cos(54) = tan(54)

x = 47×tan(54) or 47×sin(54)/cos(54)

= 64.68995026...

5)

14 is the radius of the circle.

41° is the defining angle.

then

x = sin(41)×14

= 9.184826406...

6)

the unnamed side is the radius of the circle. let's call it "s".

x is the defining angle.

then

57 = cos(x)×s

9 = sin(x)×s

9/57 = sin(x)×s / (cos(x)×s) = sin(x)/cos(x) = tan(x)

x = 8.972626615...°

Answer:

b. translation, rotation

Step-by-step explanation:

When a shape is translated, that just means nothing about it has changed except it's location on the coordinate plane. This is that happened with shape 1 - it was translated, and that created shape 2.

When a shape is rotated, that just means it is turned (or rotated) at a specific point. This is what happened to shape 2 that changed it to shape 3.

The other two transformations that aren't shown in this specific example are dilation, which means that the shape either shrinks or grows, and reflection, which means that the shape is reflected across the y-axis or the x-axis.

I included a picture with all four transformation examples in it. I hope this helps! Have a lovely day!! :)

A stack of books is 56 inches high. How high is it in feet and inches?

Answers

1 foot = 12 inches


56 inches / 12 inches = 4.66 feet = 4 feet and 8 inches

Answer:

4 feet and 8 inches

Step-by-step explanation:

To convert a high number of inches to feet you divide it by 12 since 12 inches makes 1 foot.

So 56÷12 = 4 reminder 8

The remainder we keep it as inches

So our answer is 4 feet and 8 inches.

Answer:

-1/4

Step-by-step explanation:

14x - 2x + 3 = 0
12x + 3 = 0
12x = -3
12x/12 = -3/12
x = -1/4

14x - 2x + 3 = 0

To solve for x move the constant to the other side…
14x - 2x = -3

Since 14x - 2x are the same we can subtract them…
12x = -3

Now we divide 12 by both sides, which looks like this…
12x/12 = -3/13
x = -3/12

The probability of an event happening is given as 0.45
What is the probability of the event NOT happening?

Answers

Given:

⇒ Probability of happening of an event = 45%

To Find:

⇒ Probability of event

Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.

⇒ Probability of happening event = 45/100

⇒ Probability of happening event = 0.45

⇒ Probability of non happening event = 55/100

⇒ Probability of non happening event = 0.55

Hence, the correct option is (c) 0.45.

Extra Info:

Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

Gobe weighs 53.6 kg. he wears shoes which weigh 450 gm and carries a school bag weighing 4.5 kg. if he stands on the scales in his shoes and carrying the school bag. what weight will be recorded?​

Answers

Answer:

The key to this question is converting all the mass units to the same unit and adding them all up.

The only value that isn't consistent with the other units is 450 gm or grams.

Recall that 1 gram is equal to 0.001 kilo grams. So if you want to convert grams to kilograms you would multiply that amount by 0.001 or 1/1000

[tex]450gm * \frac{1}{1000} = 0.45kg[/tex]

Now let's add up all the masses.

[tex]53.6kg + 0.45kg + 4.5kg = 58.55 kg\\[/tex]

(Now a few footnotes here, that I considered but wasn't sure about. The answer asks for weight, but you're only given mass to work with. That would be fine, if the question asked you to convert it to SI weight units like Newtons, but there's no mention of that. And also I'm not sure if the question requires significant digits. But I'll continue the answer if you think so)

To convert this into weight in Newtons, multiply by 9.81 m/s^2

[tex]58.55kg*9.81m/s^2 = 574.3755 N\\\\= 5.7 * 10^2 N[/tex]

Tracy wants to make a cylindrical model. The height of the cylindrical model, H(V), in inches, is modeled by this

equation, where Vis the volume of the cylindrical model, in cubic inches.

H(V) = 2. 6937

What is the average rate of change of the model's height when its volume changes from 512 cubic inches to

1,000 cubic inches?

The model's height increases by approximately 21. 52 inches for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 022 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 011 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 26. 9 inches for every 1-cubic-inch increase in its volume.

Answers

The average rate of change of the height function is slope of the height function

The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

How to determine the average rate of change?

The height function is given as:

[tex]H(V) = 2.69\sqrt[3]{V}[/tex]

When V = 512, the function becomes

[tex]H(512) = 2.69\sqrt[3]{512}[/tex]

[tex]H(512) = 21.52[/tex]

Similarly;

When V = 1000, the function becomes

[tex]H(1000) = 2.69\sqrt[3]{1000}[/tex]

[tex]H(1000) = 26.9[/tex]

The average rate of change is then calculated as:

[tex]H' = \frac{H(1000) - H(512)}{1000 - 512}[/tex]

This gives

[tex]H' = \frac{26.9 - 21.52}{1000 - 512}[/tex]

[tex]H' = \frac{5.38}{488}[/tex]

Evaluate the quotient

[tex]H' = 0.01102459016[/tex]

Approximate

[tex]H' = 0.011[/tex]

Hence, the model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.
