Answer:

Volume of the figure = 704 units³

Step-by-step explanation:

The figure is composed of a triangular prism and a square prism.

Volume of the figure = volume of triangular prism + volume of square prism

Volume of the figure = ½*a*b*a + a³

Given, that, a = 8 units; b = 6 units, plug in the values into the equation.

Volume of the figure = ½*8*6*8 + 8³

Volume of figure = 4*6*8 + 512

Volume of the figure = 192 + 512

Volume of the figure = 704 units³

[tex]\displaystyle \lim_{x \to 2^{+}} f(x) = 1\\\\\displaystyle \lim_{x \to 2^{-}} f(x) = 1\\[/tex]

Both result in the same limit value. This allows us to say [tex]\displaystyle \lim_{x \to 2} f(x) = 1[/tex] without the plus or minus over the 2.

The left and right hand limits may not always match like this.

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

Explanation:

The notation [tex]\displaystyle \lim_{x \to 2^{+}} f(x)[/tex] means that we are approaching x = 2 from the right hand side. This is from the positive direction. So we start at say x = 3 and move to x = 2.5 then to x = 2.1 then to x = 2.01 and so on.

Because we started with values x > 2, we will use the third definition of the piecewise function

if x > 2, then f(x) = 3x-5

Plug in x = 2 to get

f(x) = 3x-5

f(2) = 3(2)-5

f(2) = 6-5

f(2) = 1

This shows [tex]\displaystyle \lim_{x \to 2^{+}} f(x) = 1[/tex]

-----------------------------

For the other limit, we're approaching x = 2 from the negative side. So we could start at say x = 0, then move to x = 1, then to x = 1.5 then to x = 1.9 then to x = 1.99, and so on.

We're using x values such that x < 2 now.

So we'll be using the first definition of the piecewise function

If x < 2, then f(x) = x^2 - 3

f(x) = x^2-3

f(2) = 2^2-3

f(2) = 4-3

f(2) = 1

We end up with [tex]\displaystyle \lim_{x \to 2^{-}} f(x) = 1[/tex]

---------------------------------

Both right hand limit and left hand limit result in the same value

Because [tex]\displaystyle \lim_{x \to 2^{+}} f(x) = \displaystyle \lim_{x \to 2^{-}} f(x) = 1[/tex]

We can shorten that to [tex]\displaystyle \lim_{x \to 2^{}} f(x) = 1[/tex] meaning we can approach x = 2 from either direction to arrive at the same limiting value.

A thing to notice is that f(2) is not equal to 1. Instead the second line of the piecewise function says f(2) = 3.

The fact that the limit as x approaches 2 and f(2) don't agree means this function is not continuous at x = 2.

The graph shows this. We have a removable discontinuity where we effectively picked the point off the graph and move it upward.

systematic errors [ A, C], Random errors [B, D]

Step-by-step explanation:

Random errors are errors that cause certain fluctuations around the true values of substances that are measured, as a result of difficulties being experienced while taking measurements.  Systematic errors are mostly associated with the calibration of equipment. It seen to cause consistent deviations from the true value that can be gotten during measurement.

In most cases, random errors cannot be avoided while systematic errors can.

The polar coordinates of the Cartesian coordinate (1,3) is (√10, 74.49°).

To convert the Cartesian coordinate (1,3) to polar coordinates, follow the steps below:

Step 1: Plot the point (1,3) in the Cartesian plane. We have;Cartesian Plane

Step 2: Determine the distance (r) of the point from the origin using the distance formula;r = √(x² + y²)r = √(1² + 3²)r = √(1 + 9)r = √10

Step 3: Determine the angle (θ) between the positive x-axis and the line segment connecting the origin to the point (1,3).

We can find θ using any of the following formulas;

θ = tan⁻¹(y/x)θ = cos⁻¹(x/r) if x is positiveθ = cos⁻¹(x/r) + π if x is negative and y is positiveθ = tan⁻¹(y/x) + π if x is negative and y is negativeθ = ½ π if x is zero and y is positiveθ = 3/2 π

if x is zero and y is negativeθ is undefined if x is zero and y is zeroθ = cos⁻¹(1/√10) if x is positiveθ = cos⁻¹(-1/√10) + π if x is negative and y is positiveθ = tan⁻¹(3/1) + π

if x is negative and y is negativeSince x = 1 and y = 3,θ = cos⁻¹(1/√10)θ ≈ 74.49°

Step 4: Write the polar coordinates as (r, θ) using the determined values;r = √10 and θ ≈ 74.49°

c = 19sin(44°)/sin(39°) = 21.0 m

Answer:

122

Step-by-step explanation:

The complement of an angle adds up to 90.

The supplement of an angle adds up to 180.

So if the unknown angle has a complement of 32, then that angle has to be 58.   32 + 58 = 90.

You now know the angle is 58 so the supplement is

180 - 58  which is 122

1:3

Step-by-step explanation:

First, of all, keep in mind that you don't need the number of boys, because it is not in the question. Now we can look at the basic equation, which is "What is the ratio of counselors to girls." That would be Counselor: Girls. There are 10 counselors and 30 girls. Now we need to simplify the ratio. Much like simplifying a fraction, you need to simplify it with the same number. In this case, the best number to simplify with is 10, because it works with both numbers. 30 divided by 3 is 10. 10 divided by 10 is one.  Now, lets put this in an easier way to understand:

Counselor = 1

Girls = 3

So, the ratio would be 1:3.

Answer:

A) 585 miles

B) 584 miles

Step-by-step explanation:

We are told that the satellite pass directly over two tracking stations A and B, which are 90 mi apart.

This means that we can look at this as forming a kind of triangle where Tracking stations A & B will be

opposite ends of the base of the triangle while the satellite position will be the apex of the triangle.

We are given the angles of elevation at A and B to be 87.0° and 84.2° respectively.

Now, if we depict the satellite position as C. Then we have;

Angle at C = 180 - (87 + 84.2)

Angle at C = 8.8°

I've attached an image depicting this triangle.

A) To find the distance of the satellite from Station A, from the image attached, the distance will be AC.

Since AB is 90 mi.

Thus, using sine rule, we have;

AB/sin C = AC/sinB

Plugging in the relevant values;

90/(Sin 8.8) = AC/(sin 84.2)

AC = (90 × (sin 84.2))/(Sin 8.8)

AC = 585.27

To the nearest mile gives;

AC = 585 miles

B) To find out how high the satellite is above the ground, is the perpendicular distance from point C to line AB

Let's call the point at which the line touches AB as D.

It means angle D is 90° and it means triangle ADC it's a right angled triangle where AC is the hypotenuse = 585 miles.

Thus, using Trigonometric ratios we can find CD

Sin(87) = CD/585

CD = (Sin 87) x 585

CD = 584.198 miles

Approximating to the nearest mile gives;

CD = 584 miles

Answer:

Distance from A to Satellite: 1832.951 miles

Distance from satellite to ground: 1830.439 miles

Step-by-step explanation:

Answer: So unfortunately a lot of these answers for this question are not answering it correctly for the way that it is asked, which is not their fault because they cannot see the image in which it is referring to. Thats because in this question when it says the angle of elevation of A is 87° it is actually talking about the angle OUTSIDE of side A in the image, NOT THE INSIDE ANGLE. meaning that the inside angle across from angle B at 84.2 is actually 93° not 87°. (since it is the corresponding angle on a 180° line and we follow the geometric laws).

Now say we name the triangle ABC, we now have INNER ANGLE A at 93° and INNER ANGLE B at 84.2°.

To get INNER ANGLE C you subtract both ANGLE A & B added together from 180° to get ANGLE C since the all interior angles of a triangle = 180°

180°-(93°+84.2°)=2.8° so INNER ANGLE C =2.8°

Now we can use the LAW OF SINES to find the LENGHT OF SIDE "a"(lower case) (DISTANCE from A to C)(Which is Distance from Satellite to Station A)

DISTANCE FROM A TO C is referred to side "b" (lower case), as it is the side across from the INNER ANGLE B, same as side "c" (lower case) is DISTANCE FROM A TO B, as it is across from INNER ANGLE C.

LAW OF SIGNS EQUATION

b/sinB= c/sinC which means:

b/sin(84.2)=90/sin(2.8)

Which equates to c=90sin84.2/sin(2.8)

Which = 1832.951 (DISTANCE FROM SATELLITE TO A)

NOW to find the DISTANCE FROM THE SATELLITE TO GROUND: Draw a straight line down from satellite making a new RIGHT TRIANGLE.

Even though it is a RIGHT TRIANGLE (Call it XAC, X being the GROUND ANGLE) you can still use the Law of Sines to figure out the HEIGHT FROM GROUND TO SATELLITE.

This is where the 87° ANGLE comes in. With the new RIGHT TRIANGLE we have created, we know 2 of the interior angles: 87° and 90°. to find last interior angle just add together and subtract from 180.

180°-(87°+90°)=3°

Since we know side a SIDE "a" from previous Triangle, it now just becomes SIDE "x" (DISTANCE FROM A TO SATELLITE) which is 1832.9 miles.

Now use law of sines to find new side A (DISTANCE FROM X(GROUND) to SATELLITE(C)

The equation would be:

a/sinA=x/sinX which is

a/sin87=1832.951/sin90 which equates:

1832.951sin(87)/sin90=

1830.439 miles.

Very long and hard problem especially without image which I shall add. Good effort to everyone who tried to answer problem, it was correct if ANGLE A was inside the 2 SATELLITES, unfortunately it just wasn't the right way to find the answer that the actual question being asked (or I assume the actual question since I had it in my homework as well), which again was impossible to know without the image the problem gave.

I could never find the right answer for this problem so I made this to try and help others once I finally found the right answer (which I did finally get correct on the homework so I know this is correct, my problem simply had the distance from A to B as 80 Miles so I just reworked it for this problem with 90 miles instead. It is the same procedure no mater the values you are given, just replace them with the ones you're being asked)
