a small publishing company is planning to publish a new book. Let C be the total cosy of publishing the book. Rest is in the picture help please
Answers
The domain is the number of copies and the values is 0 to 200, while the range is the cost of publishing and the values is 5000 to 5500
How to determine the domain and the range?The function is given as:
C = 25N + 500
From the question, we understand that the company can only publish up to 200 books.
This means that the possible number of books to publish is 0 to 200 (this represents the domain)
At the minimum number of publish (i.e. 0), we have:
C = 25 * 0 + 500 = 50
At the maximum number of publish (i.e. 200), we have:
C = 25 * 200 + 500 = 5050
Hence, the domain is the number of copies while the range is the cost of publishing

Motorbikes have two wheels and cars have four wheels. There are a number of
motorbikes and cars in a parking lot. There are 14 motorbikes. Altogether, there are
324 wheels. How many cars are in the parking lot?
A.74 cars
B.148 cars
C.296 cars
D.310 cars
Answers
Answer:
74 Cars
Step-by-step explanation:
If each motorbike has 2 wheels then we need to find how many wheels the motorbikes already take up.
We do this by doing 14*2 and we get 28 wheels.
Afterwards, we subtract this from the total of 324 to see how many wheels are left over. 324-28=296
Now we know the remaining amount of wheels and with this we can get our final answer!
Since there are 296 remaining wheels and each car takes up 4 we can divide 296 by 4 to see how many cars would be able to get their full set of tires.
296/4 = 74 and that;s how you get 74 cars!

Answers
Answer:
Multiply the number of inches on the map times the scale to determine the true distance. For example, if the distance on the map was 5.5 inches and the scale was 1:6,336,000, the true distance would be 550 miles. To convert an area, convert the dimensions using the scale and then find the true area.

Solve for the value of k.
Answers
Answer:
k = 13
Step-by-step explanation:
The sum of the angles is 180 since they form a straight line
4k-7 + 90 + 3k+6 = 180
Combine like terms
7k+89=180
Subtract 89 from each side
7k+89-89 = 180-89
7k =91
Divide each side by 7
7k/7 = 91/7
k = 13
For one roadway section, the average number of cars passing a point is 2200 pcphpl (i.e. passenger cars per hour per lane). The cars travel at an average speed of 42 mph. What is the average distance (in feet) between common points (e.g. the front bumper) on successive cars in one lane
Answers
Answer:
The average distance between common points on successive cars in one lane is of 100.8 feet.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
The cars travel at an average speed of 42 mph
Each mile has 5280 feet, so in 1 hour, the distance is of 42 miles = 221760 feet.
2200 pcphpl (i.e. passenger cars per hour per lane).
2200 cars in 221760 feet. Thus:
[tex]d = \frac{221760}{2200} = 100.8[/tex]
The average distance between common points on successive cars in one lane is of 100.8 feet.

Step-by-step explanation:
Substitute for f and g, then collect terms.
(f -g)(x) = f(x) -g(x) = (4x -3) -(x +4)
(f -g)(x) = 4x -3 -x -4 = (4-1)x +(-3-4)

Answers
Complete question :
Martin deposits $200 in a savings account that earns 5% annual interest. four years later, cary deposits $200 in an account earning the same interest. let m represent the balance in martins account and let c represent the amount of money in carys account. choose the pair of expressions that describe the accounts y years after martin opened his account. martin: 200(1.05)y cary: 200(1.05)y+4 martin: 200(1.05)y+4 cary: 200(1.05)y4 martin: 200(0.05)y cary: 200(0.05)y4 martin: 200(1.05)y cary: 200(1.05)y4 choose the equation that relates the balances in the accounts y years after martin opened his account. c = m(1.05)4y m = c(1.05)4y c = 1.22m m = 1.22c
Answer:
m = m = 200(1.05)^y+4
c = m = 200(1.05)^y
m = 1.22c
Step-by-step explanation:
The future value can be represented as :
Future value, F = P(1 + r)^n
r = interest rate = 5% = 0.05 , n = number of years ;
For Martin :
m = 200(1 + 0.05)^n
For cyan :
c = 200(1 + 0.05)^n
y years after Martin
Cyan opened 4 years after Martin :
Representing in terms of y
Cyan = y ; Martin = y +4
m = m = 200(1.05)^y+4
c = m = 200(1.05)^y
From. Indices :
(1.05)^y+4 = 1.05^y * 1.05^4
Hence,
m = 200 * 1.05^y * 1.05^4
c = 200 * 1.05)^y
Hence,
m = c * 1.05^4
m = c * 1.2155
m = c * 1.22
m = 1.22c

An isosceles triangle has two 5.5 cm sides and two 32.4° angles. Explain how to determine the perimeter of the triangle. Include a diagram in your solution. You do NOT need to solve.
Answers
Answer:
see below
Step-by-step explanation:
The drawing in blue is what we are told in the problem.
We are given two sides and two angles. It is an isosceles triangle with two equal sides and two equal angles. Draw a perpendicular bisector ( it makes a 90 degree angle. Now we have two identical right triangles. We can use trig functions to find x
cos theta = adj/ hyp
cos 32.4 = x / 5.5
Solving for x
5.5 cos 32.4 =x
Now we have 2x for the third side of the triangle
2( 5.5 cos 32.4) is the third side
P = 5.5 + 5.5 + 2( 5.5 cos 32.4)
Answer:
See the Below
Step-by-step explanation:
Draw a circle with a radius of 5.5 and center at A.Take any point B on the circle and join AB.Draw a line thru B making an angle 32.4 with AB which intersects the circle at D. Extend AD on both sides.Draw two circles with a radius of 5.5cm and centers B and D which intersect the line BD at E and F.Measure length EF, which is the perimeter of triangle ABD.=20.3 cm.Method 2. Assume that base of the triangle =x cm.x/2= 5.5 cos 32.4 and x=11*cos 32.4 =11*0.844=9.287Perimeter = 20.287

6x - 21 = 105 (vertically Opposite angles)
6x = 105 + 21
6x= 126
x=126/6
x= 21°
That should be the fifth option
OR
Another Way of solving
(6x - 21) + 75 = 180 ( angles on a straight line)
6x -21 + 75 =180
6x + 54 = 180
6x =180 - 54
6x = 126
x=126/6
x=21°
[tex] \large \sf \star \: \green{Answer} \: \star[/tex]
x = 21 °
Step-by-step explanation:
Here,
Angle 75 ° and ( 6 x - 21 ) are on straight line so it's supplementary angles and we know that sum of all angles of supplementary angles is 180 °.So, 6 x - 21 ° + 75 ° = 180 °6 x - 21 ° + 75 ° = 180 °
6 x + 54° = 180 ° ...( Combine like terms)
subtract 54 ° from each sides
54° - 54° + 6 x = 180 ° - 54 °
6 x = 126°
x = 126 ° / 6 ...( Divide by 6 )
x = 21 °

(viii) 116 ± 2.78 x 14.4√5
(ix) 116 ±2.78 x 14.4√4
Answers
Answer:
(viii) 116 ± 2.78 x 14.4√5
Step-by-step explanation:
The given data is
Sample size =n= 5
Calculated t- value= 2.4837
Mean= 116
Standard deviation= sd= 14.40486
The t - value from table with 4 d.f for ∝/2 is t∝/2 (n-1)= 2.776
The 95% confidence interval is calculated by
d` ± t∝/2 (n-1) *sd/√n
Putting the values
116 ± 2.776* 14.40486/√5
Comparing these values with the options Part viii gives the best answer.
(viii) 116 ± 2.78 x 14.4√5
2.776 when rounded gives 2.78 and 14.40486 when rounded gives 14.4
The rest are incorrect.

If they continue at this rate, who do you predict will win the race? justify your
prediction
How many seconds have elapsed when Big Claw and Flicker are tied?
Answers
Answer: Crayfish, 25 s
Step-by-step explanation:
Given
The length of race is 60 cm
Flicker gets a 10 cm head-start
Cray fish covers 6 cm in 5 s i.e. its speed is
[tex]\Rightarrow \dfrac{6}{5}=1.2\ cm/s[/tex]
Flicker covers 4 cm in 5 s, its speed is
[tex]\Rightarrow \dfrac{4}{5}=0.8\ cm/s[/tex]
Time taken by Cray fish to cover the race is
[tex]\Rightarrow t_1=\dfrac{60}{1.2}\\\\\Rightarrow t_1=50\ s[/tex]
Time taken by flicker to cover race with 10 cm head start
[tex]\Rightarrow t_2=\dfrac{60-10}{0.8}\\\\\Rightarrow t_2=62.5\ s[/tex]
Time taken by crayfish is less. Hence, crayfish wins the race
When they both covers the same distance, they tied momentarily i.e.
[tex]\Rightarrow 1.2t=10+0.8t\\\Rightarrow 0.4t=10\\\\\Rightarrow t=\dfrac{10}{0.4}\\\\\Rightarrow t=25\ s[/tex]
After 25 s, they tied the race.
