Answer:
a) after 12.59 days the revenue will be equal
b) u just have to graph it
the second one is
a) the two solutions are x=4 and x=-4
b) x=-4 is not reasonable because time can’t be negative
c) after four seconds, the heights will be equal
Step-by-step explanation:
After 12.59 days the revenue for each game is the same. The two solutions of the system equation b(t) and p(t) are 4 and -4, and -4 is not a reasonable solution because time never be negative and after 4 seconds the rocket and the ball reach the same height.
1)
Given :
Math Game -- [tex]\rm M(d) = x^2-9x-10[/tex]
Reading Game -- R(d) = 2x + 10
It is given that after 'x' number of days the revenue for each game is the same, that is:
[tex]\rm x^2 -9x-10=2x+10[/tex]
[tex]\rm x^2 -11x-20=0[/tex]
Simplify the above quadratic equation.
[tex]\rm x = \dfrac{11\pm \sqrt{11^2-(4\times -20)} }{2}[/tex]
[tex]\rm x = \dfrac{11\pm \sqrt{201} }{2}[/tex]
x = 12.59 days
So, after 12.59 days the revenue for each game is the same.
The graph of both the revenue function is attached below.
2)
Given :
[tex]\rm b(t) =- t^2-2t+36[/tex]
p(t) = -2t + 20
The solution of this system can be determined by equating both the above function.
[tex]\rm -t^2 - 2t +36 = -2t +20[/tex]
Simplify the above equation.
[tex]\rm t^2 =16[/tex]
t = 4 and -4
a) The two solutions of the system are 4 and -4.
b) -4 is the solution is not a reasonable solution because time never be negative.
c) After 4 seconds the rocket and the ball reach the same height.

Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10?
Answer:
The sequence generated will be 10,8,6,4,2,......
Step-by-step explanation:
We want to generate a sequence here
f(n + 1) = f(n) - 2
f(1) = 10
So f(2) = f(1) - 2 = 10 -2 = 8
f(3) = f(2) - 2 = 8-2 = 6
f(4) = f(3) -2 = 6-2 = 4
f(5) = f(4) - 2 = 4-2 = 2
So the sequence will be ;

Answer:
1.) x = 37
2.) m<SVW = 74 deg
3.) m<TWV = 106 deg
Step-by-step explanation:
Linea SY and TZ are shown to be parallel.
Angles SVW and TWV are same-side interior angles.
Theorem:
If parallel lines are cut by a transversal, then same-side interior angles are supplementary.
m<SVW + m<TWV = 180 (by the definition of supplementary angles)
2x + 3x - 5 = 180
5x - 5 = 180
5x = 185
x = 37
m<SVW = 2x = 2(37) = 74
m<TWV = 3x - 5 = 3(37) - 5 = 111 - 5 = 106
Answer:
1.) x = 37
2.) m<SVW = 74 deg
3.) m<TWV = 106 deg

A rectangular car park is being measured so that a fence can be constructed around it.The width of the car park is 12 m, correct to the nearest metre. The length of the car park is 34 m, correct to the nearest metre.What length of fence should be ordered to guarantee that there will be enough to surround the car park?
Answer:
92mStep-by-step explanation:
Since we are to construct the fence around the park, to determine the length of the fence, we will find the perimeter of the rectangular car park.
Perimeter of the car park = 2(Length + Width)
Given
Width of car park = 12m
Length of the car park = 34 m
Substituting the given data into the formula;
Perimeter of the park = 2(12+34)
Perimeter of the park = 2(46)
Perimeter of the park = 92m
Hence the length of fence that should be ordered to guarantee that there will be enough to surround the car park is 92m

Write 49 as a product of two primes.
Answer:
49 = 7 x 7
Step-by-step explanation:
if we factor out 49 into its prime factors, we will get
49 = 7 x 7
(this is the answer)
Alternatively, we can recall from our multiplication tables that 49 = 7² = 7 x 7 (which gives the same answer)
Answer:
7² or 7x7
Explanation:
The prime is any number that can only be divided by itself or by one. One is not a cousin. The only prime pair is 2, all the others are unpaireds.
7/7 = 1. 7/1 = 7
7x7 = 49 or
7² = 49.

9 = 3²

PLEASEEE HELP On a coordinate plane, the vertices of triangle ABC are A(−3, 1), B(6, 4), C(2, 5). The vertices are translated 4 units to the right and down 3 units.
1. Write a rule, P(x, y) → P'(x + a, y + b), that represents the translation.
2. What are the coordinates after the translation?
Answer:
A (1,-2) B(10,1) C(6,2)
Step-by-step explanation:
You add 4 to the x value and subtract 3 from the y value to get the answer.
The coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).
How to calculate the coordinates?To represent the given translation, we need to add the same constant amount to the x-coordinate of each vertex and subtract the same constant amount from the y-coordinate of each vertex.
Let's call the constants of translation "a" and "b", respectively. Then the rule P(x, y) → P'(x + a, y - b) represents the translation of a figure where P is any point in the original figure and P' is the corresponding point in the translated figure.
To find the coordinates after the translation, we need to apply the translation rule to each vertex of the triangle.
For vertex A(-3, 1), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of A': (-3 + 4, 1 - 3) = (1, -2).
For vertex B(6, 4), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of B': (6 + 4, 4 - 3) = (10, 1).
For vertex C(2, 5), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of C': (2 + 4, 5 - 3) = (6, 2).
Therefore, the coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).

Eight cars are to be parked in a row for viewing at a fair. Three of the cars are the same colour and are to be kept together in the viewing row. Determine the number of possible arrangements of the cars, given that the three cars of the same colour are kept together.
Answer:
720 possible arrangements.
Step-by-step explanation:
The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.
What is combination?The combination is a way of selecting items from a collection where the order of selection does not matter.
We have,
Number of cars = 8
Number of cars that are the same in color = 3
Cars that are the same in color can be arranged = 3!
There are 8 cars such that,
1 2 3 4 5 6 7 8
Three cars of the same color are taken out and we have,
1 2 3 4 5
We see that there are six spaces = 6!
where we can put the same color cars together so,
The possible arrangement of the cars, given that the three cars of the same color are kept together:
= 3! x 6!
= 3 x 2 x 1 x 6 x 5 x 4 x 3 x 2 x 1
= 4320
Thus,
The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.
