Answer:

Lowest angle of elevation is 20.8

Step-by-step explanation:

If he is in the middle of the field, then the 100 value is split in half.

Then, you do 20-1 because of the height of the telescope.

So now, to solve:

tanx= 19/50 (opposite over adjacent)

x= tan^-1 times (19/50)

19 devided by 50= 0.38

then do 0.38 tan^-1

and round.

Therefore the answer is 20.8

Answer:

y = 8x - 5

Step-by-step explanation:

Given:

To find:

How to find:

The slope is always known as "constant of variation" or "rate of change", but it's basically the increase of both y and x axes in simple terms. The decrease or increase in two points together and then found with the formula of rise/run (increase and decrease) (horizontal line/vertical line).

The y-intercept is always on the y-axis and is the beginning of what is learned in pre-algebra as a "story" which helps students practice finding the slope which again, is the change with "per" or "each".

Make sure to use the formula:

y = mx + b

Now we insert.

y = 8x <---------- slope

y = 8x - 5 <------ y-intercept and completed slope-intercept equation.

The reason it has a negative is because it started out as a negative y-intercept and is increasing by 8 through ordered pairs.

Answer:

y = 8x - 5

Step-by-step explanation:

because if its has a slope of 8 then m is 8

if the y intercept is -5 the b is -5

y = mx + b

y = 8x -5

Given that,

Natasha can hit a bullseye about 95% of the time

we've to find the number of throws will she

need in order for her to hit 76 bullseyes

for that, we'll divide 76 by 95%

[tex] \huge \rightarrow \: 76 \div \frac{95}{100} = \frac{76}{\frac{95}{100} } \\ [/tex]

Hence, she need 80 bullseye in order for her to hit 76 bullseyes

Answer:

Step-by-step explanation:

P(hit a bulleye) = 95% = 0.95

P(hit 2x bulleyes) = 0.95*0.95

P(hit 76x bulleyes) = 0.95^76

= 0.02

So she will hit 76 bulleyes on average every 1/0.02 = 50 times.

Total number of throws = 50 x  76

Answer:

[tex]y=3^x[/tex]

Step-by-step explanation:

exponential function : y = a(b)^x

where a = y intercept and b = factor ( number you are multiplying by )

according the the graph the y intercept is a 1 so a = 1

we now have y = 1(b)^x

to find the factor you plug in one of the ordered pairs into y = 1(b)^x

the ordered pair you use will not effect the outcome, i have chose (2,9)

y = 1(b)^x

(x,y) = (2,9) so x = 2 and y = 9

9 = 1(b)^2

divide both sides by 1

9 = (b)^2

take the square root of both sides

3 = b

the final equation is y = 1(3)^x or just y = 3^x

Answer:

h(t) = -16t² + 200

distance = 56 ft

Step-by-step explanation:

First of all, we know that the initial velocity (v0) of the rock is 0 ft/s because the rock was dropped. We also know that the initial height of the rock is 200 ft because it was dropped at the top of the well which is 200 ft high. Plugging this information into our quadratic function we get h(t) = -16t² + 200.

Now we need to find the distance from the surface of the water to the bottom of the well. This distance is equal to the height of the rock at time equals 3 seconds. Therefore, all we need to do is find h(3) = -16(3)² + 200 = 56 ft.

Answer: Angle LPO

Step-by-step explanation:

Answer:

yes it is the right angle

Answer:

3. m∠1 = 106° ~ this is because ∠1 and ∠2 together make a straight line and are therefore supplementary, meaning added together, they equal 180° (so I did 180° - 74° = 106°)

4. m∠3 = 74° ~ again, it is supplementary to ∠1. It is also equal to ∠2

5. m∠8 = 114° ~ angles opposite of each other (like 1 and 4) are equal (as we know from question 4). From there, we can use the corresponding angle theorem, so we know 4 and 8 are congruent. (also you can just know 1 and 8 are congruent by using the opposite exterior angles theorem)

6. m∠6 = 124° ~ using same-side interior angle theorem, they are supplementary angles (or the corresponding angles theorem mentioned above, make 4 congruent to 8, and 8 is supplementary to 6)

7. m∠7 = 96° ~ using same side exterior angle theorem, these angles are supplementary

8. m∠2 = 64° ~ again, same side exterior angle theorem

Answer:

Let c be the common factor between Jill and Kelly’s money. Then:

4n-156 / 5n-156=8/11

So:

44n-1716=40n-1248

4n=468

n=117

Jill had 4n, or $468 to begin with

Kelly had 5n, or $585 to begin with ………..

Answer:

Step-by-step explanation:

x=Jill's money

y=Kelly's money

x/y=4/5

(x-156)/(y-156)=8/11

x/y=4/5 -------->5x=4y --------->y=5x/4

cross multiply with the above proportion

11(x-156)=8(y-156)

11x-1716=8y-1248

substitute y=5x/4

11x-1716=8(5x/4)-1248

11x-1716=10x-1248

11x-10x=1716-1248

x=$468 for Jill  (answer)

x/y=4/5

468/y=4/5

multiply 4 by 117 to get 468

multiply 5 by 117 to get 585

y=$585 for Kelly (answer)   (or cross multiply to find y)

11pi/4

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

Explanation:

The angles shown add to: 120+45+30 = 195 degrees.

The remaining bit needed to get to a full 360 degree circle is 360-195 = 165 degrees, which is the measure of central angle AFD.

This means the arc AED is 165/360 of the full circle perimeter or circumference.

The fraction 165/360 reduces to 11/24 after dividing both parts by the GCF 15

So we can say that the length of arc AED is exactly 11/24 of the full circumference.

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

The length FB is 3 units (radius), so EB is 6 units (diameter)

This leads to,

C = circumference

C = pi*diameter

C = pi*6

C = 6pi

That's the full circumference, but we only want 11/24 of it to get arc AED.

arc AED = (11/24)*(full circumference)

arc AED = (11/24)*(6pi)

arc AED = 11pi/4 which is choice D

I'm assuming choice D says 11pi/4

Answer:

y=900x-1700

Step-by-step explanation:

(sorry if the explanation is long)

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (2,100), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=2 and y1=100.

Also, let's call the second point you gave, (3,1000), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=3 and y2=1000.

Now, just plug the numbers into the formula for m above, like this:

m=

1000 - 100

3 - 2

or...

m=

900

1

or...

m=900

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=900x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(2,100). When x of the line is 2, y of the line must be 100.

(3,1000). When x of the line is 3, y of the line must be 1000.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=900x+b. b is what we want, the 900 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (2,100) and (3,1000).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.

You can use either (x,y) point you want..the answer will be the same:

(2,100). y=mx+b or 100=900 × 2+b, or solving for b: b=100-(900)(2). b=-1700.

(3,1000). y=mx+b or 1000=900 × 3+b, or solving for b: b=1000-(900)(3). b=-1700.

See! In both cases we got the same value for b. And this completes our problem.

The equation of the line that passes through the points

(2,100) and (3,1000)

is

y=900x-1700

Answer:

y=900x-1700

Step-by-step explanation:

(sorry if the explanation is long)

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

Answer:

x= 6.324555320

Step-by-step explanation:

X^2=40

1. Square root both sides

2. You should be left with x=6.32....

Solution: √40 = x

So basically, you have to find x, which is raised to the power of two. To find that, we'll have to square root 40 because square rooting a number is the opposite of squaring a number

So 40 squared = 6.32455532034

A really long number...

Now, let's check our answer

6.32455532034^2 = 40

So therefore, x = 6.32455532034

Answer:

Percent error is approx. 22%

Step-by-step explanation:

So to do this you need to know the formula for percent error, which is

percent error = l measured - theoretical / theoretical l * 100%

With this just plug in 18 (real) and 14 (measured).

percent error = l 14 - 18 / 18 l * 100%

percent error = l -4 / 18 l *100%

percent error = l -2/9 l *100%

You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.
