Answer:

(-2,3)

Step-by-step explanation:

You can see that the purple is the new triangle. So look at the coordinate of the D. You can see that it is plotted at (-2, 3)

Answer:

(-2, 3)

to find the point of something you first find where uts standing on the x-axis (vertical line) and then where its standing on the y-axis (horizontal line)

Answer:

  1 1/6 hours

Step-by-step explanation:

Assuming distance and time are proportional, 2/3 of the 1 3/4 hours remain:

  (2/3)(7/4) = 14/12 = 1 1/6 . . . . hours remain

The trip will take 1 1/6 hours longer.

Answer:

the answer is 1 1/6 hours

Answer:

  (i) not continuous at x=2

  (ii) -√2

Step-by-step explanation:

(i) The function simplifies to ((x -2)(x+2))/(x -2) = x +2 . . . . x ≠ 2

The left and right limits at x=2 exist and are the same: 4. However, the function is undefined at x=2, so the conditions for continuity are not met.

__

(ii) The expression is indeterminate (0/0) at x=π/4, so  L'Hopital's rule can be used to find the limit.

  lim[x→π/4] = ((d/dx)(cos(x)-sin(x)))/((d/dx)(x-π/4)) = (-sin(π/4)-cos(π/4))/1

  lim[x→π/4] = -√2/2-√2/2 = -√2

The limit is -√2.

Answer:

-2/5

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

= ( 3-9)/(0+15)

= -6/15

= -2/5

Answer:1.53

Step-by-step explanation:

Answer:

Case 1 - 50388 ways when the couple is there in the group of 8 people selected out of 20 employees.

Case 2 - 75582 ways when the couple is not there in the group of 8 people selected out of 20 employees.

Step-by-step explanation:

Given

The couple within the group can not be separated and hence instead of taking total 20 employees , it must be taken as 19 employees.

Now if the couple is there in the selected group of 8 people, then total 7 needs to be selected out of 19 and hence the total number of ways of selecting 7 people out of 19 is

[tex]^7C_{19}[/tex] = 50388

If the couple is not there in the selected group of 8 people, then the total number of ways of selecting 8 people out of 19 is

[tex]^8C_{19}[/tex] = 75582

Answer:

$33.75

65%

$13.78

Step-by-step explanation:

commission earned = percentage commission x worth of goods sold

4 1/2% x $750

4.5% x $750

0.045 x $750 = $33.75

Percentage mark-up = [(selling price - cost price) / cost price] x 100

[(90.75 - 55) / 55) x 100

= 65%

new income = 6% of $13 + 13

0.06 x 13 = $0.78

$13 +  $0.78 = $13.78

Answers:

First one is 130r

and

Second one is n(r*r)

Answer:

Part A;

- Increases

- Increases

Part B:

- Constant but not 0

- 0

Step-by-step explanation:

Part A:

>> Looking at the speed - time graph of Airplane A, we can see that speed increases from rest at 0 seconds time to time.

>> In graph of airplane B, we can see that distance gradually increases from time at 0 to time at t1. This means that the speed is increasing.

Part B:

>> From time t1 to time t2, we see in airplane A graph that the motion is indicated a horizontal line which means there is constant motion and in constant motion, speed is constant but not zero.

>> In graph of airplane B, we see that the distance between time t1 to time t2 didn't increase. This means that there was no movement. As a result, speed will be 0

Your on your own.. :/

Answer:

I can't understand your equation. Please rewrite it.

Step-by-step explanation:

Answer:

x<26

Step-by-step explanation:

8(x/4 - 6) < 4

Divide both sides by 8;

8(x/4 - 6)/8 < 4/8

Simplify;

x/4-6<1/2

Add 6 to both sides;

x/4-6+6<1/2+6

Simplify;

x/4-6+6<1/2+6

Simplify

x/4-6+6

=x/4

Simplify;

1/2+6

Convert it into a fraction;

6*2/2+1/2

Since the denominators are equal combine the fractions;

6*2+1/2

6*2+1=13

=13/2

x/4<13/2

Multiply both sides by 4;

4x/4<13*4/2

Simplify 4x/4

4x/4

4/4=1

=x

Simplify 13*4/2

Multiply the numbers:13*4=52

=52/2

Divide the numbers:52/2=26

=26

x<26

HOPE THIS HELPED!!!

Answer:

261

Step-by-step explanation:

→ Substitute 2 into g( x )

( 3 × 2 ) + 10 = 16

→ Substitute that answer into f( x )

16² + 5 = 261

Answer:

[tex]\huge {\purple {a_{50} = 153}} [/tex]

Step-by-step explanation:

Given sequence is 3n + 3

[tex] \implies a_n = 3n + 3[/tex]

Plug n = 50

[tex] \implies a_{50} = 3(50) + 3[/tex]

[tex] \implies a_{50} = 150 + 3[/tex]

[tex]\huge {\red {\implies a_{50} = 153}} [/tex]

We have ,

=> T_n = a + ( n - 1)d

=> T₅₀ = 3n + 3

=> T₅₀ = 3(50) + 3

=> T₅₀ = 150 + 3

=> T₅₀ = 153

Answer:

no of students 63

the answer is...

21

Answer:

Step-by-step explanation:

In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model.   Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).

The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.

Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.

However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.

Hence, various measures like either goodness of fit or theory testing, would be used for this.

Answer:

B. the mean is 59 inches

Step-by-step explanation:

if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.

Answer:

B: The mean wingspan is 59 inches.

Step-by-step explanation:

The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.

Answer:1566

Step-by-step explanation:

Answer:

  x = 12

Step-by-step explanation:

An inscribed angle has half the measure of the arc it intercepts.

  arc SU +arc UT = 180°

  2(43°) +(9x -14)° = 180°

  9x = 108 . . . . . . . divide by °, subtract 72, simplify

  x = 12 . . . . . divide by 9

Answer:

0.50 cents

Step-by-step explanation:

If we're going to need the price for 1, we're going to need to divide. So, with the known information, we take 5$ (or 5.00$) and divide it by 10 hamburgers to get your quotient of .50 cents . If I'm wrong, please don't be afraid to correct me. And have a good day stranger!
