Answer:
Catcher's number = 17
Pitcher's number = 18
Step-by-step explanation:
Let two consecutive numbers be represented by x and (x + 1)
Hence,their product
= x(x + 1) = 306
= x² + x - 306 = 0
We factorise
= x² + 18x - 17x - 306 = 0
= x(x + 18) - 17(x + 18) = 0
= (x + 18)(x - 17) = 0
x + 18 = 0 = -18
x - 17 = 0 = 17
x = 17 and -18
Our answer can't be a negative integer
Hence x = 17
The second consecutive integer = x + 1
= 17 + 1 = 18
Hence the uniform numbers are 17 and 18.
We are told in question that: If the catcher's was the smaller number, determine the uniform number of each player.
Therefore,
The Catcher's uniform number = 17
The Pitcher's uniform number = 18

Describe how to transform the graph of f into the graph of g. f(x) = x2 and g(x) = -(-x)2 The graph shifts left one unit. Reflect the graph of f across the y-axis and then reflect across the x-axis. Reflect the graph of f across the y-axis. Reflect the graph of f across the x-axis.
Answer:
Reflect the graph of f across the y-axis and then reflect across the x-axis.
Step-by-step explanation:
Reflection rules:
Reflection over x -axis:(x,y)→(x,-y)
Reflection over y-axis : (x,y)→(-x,y)
Graph:[tex]y= f(x)=x^2[/tex]
We are given that the graph of f into the graph of g.
[tex]f(x) = x^2[/tex] and [tex]g(x) = -(-x)^2[/tex]
Reflect over y axis.
Reflected graph [tex]=(-x)^2[/tex]
Reflect the obtained graph over x axis
[tex]g(x)=-(-x)^2[/tex]

Yummy Cookies just opened a brand new cookie bakery, ans sales are increasing every month! In January, the baker made 14 carrot cake cookies. In February, the baker doubled the January order, took 5 cookies home to his family, and sold the rest. If the baker continues to double the full amount and then bring 5 cookies home to his family, how many cookies will the baker sell in March and April?
Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.

Answer:
x = [tex]-7\frac{2}{3}[/tex]
Step-by-step explanation:
=> 6(2x+11) + 15 = 3x+12
(Expand the brackets)
=> 12x+66+15 = 3x+12
(Adding 66+15)
=> 12x+81 = 3x+12
(Subtracting 81 and 3x to both sides)
=> 12x-3x = 12-81
=> 9x = -69
(Dividing both sides by 9)
=> x = [tex]\frac{-69}{9}[/tex]
(Simplifying)
=> x = [tex]\frac{-23}{3}[/tex]
(Converting it into mixed form)
=> x = [tex]-7\frac{2}{3}[/tex]
So, x = [tex]-7\frac{2}{3}[/tex] will make the equation true.

A bridge connecting two cities separated by a lake has a length of 5.651 mi.
Use the table of facts to find the length of the bridge in yards.
Round your answer to the nearest tenth.
Answer:
The equivalent of 5.651 mi is 9945.76 yards
Step-by-step explanation:
Given:
Length of lake = 5.651 mi
Required:
Length of bridge in yards
From table of facts;
1 mile = 1760 yards
This implies that
5.651 miles will be:5.651 * 1760 yards
5.651 * 1760 yards = 9945.76 yards
5.651 * 1760 yards = 9945.8 yards (Aproximated)
Hence, the equivalent of 5.651 mi is 9945.76 yards
Use the method of equating coefficients to find the values of a, b, and c: (x+4)(ax2+bx+c)=2x3+9x2+3x−4
Answer:
[tex]a = 2; b = 1\ and\ c = -1[/tex]
Step-by-step explanation:
Given
[tex](x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
Required
[tex]Find\ a,b,c[/tex]
[tex](x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
Open Bracket
[tex](x)(ax^2+bx+c)+(4)(ax^2+bx+c)=2x^3+9x^2+3x-4[/tex]
[tex]ax^3+bx^2+cx+4ax^2+4bx+4c=2x^3+9x^2+3x-4[/tex]
Collect like terms
[tex]ax^3+bx^2+4ax^2+cx+4bx+4c=2x^3+9x^2+3x-4[/tex]
By comparing coefficients; we have
[tex]ax^3=2x^3\\bx^2+4ax^2=9x^2\\cx+4bx=3x\\4c=-4[/tex]
Remove all traces of x from both sides
[tex]a=2\\b+4a=9\\c+4b=3\\4c=-4[/tex]
From the first equation;
[tex]a = 2[/tex]
From the last equation
[tex]4c = -4[/tex]
Divide both sides by 4
[tex]\frac{4c}{4} = \frac{-4}{4}[/tex]
[tex]c = \frac{-4}{4}[/tex]
[tex]c = -1[/tex]
Substitute -1 for c in the third equation
[tex]c+4b=3[/tex]
[tex]-1 + 4b = 3[/tex]
Add 1 to both sides
[tex]1-1 + 4b = 3+1[/tex]
[tex]4b = 4[/tex]
Divide both sides by 4
[tex]\frac{4b}{4} = \frac{4}{4}[/tex]
[tex]b = \frac{4}{4}[/tex]
[tex]b = 1[/tex]
Substitute 2 for a in the second equation [To confirm the value of b]
[tex]b+4(2)=9[/tex]
[tex]b + 8 = 9[/tex]
Subtract 8 from both sides
[tex]b + 8 - 8 = 9 - 8[/tex]
[tex]b = 1[/tex]
Hence;
[tex]a = 2; b = 1\ and\ c = -1[/tex]

how does the fact that a parallelogram has rotational symmetry demonstrates that opposite side of a parallelogram are congruent ?
Answer:
See below.
Step-by-step explanation:
It is known that a parallelogram has rotational symmetry, rotated 180 degrees about it's center point. Now by definition a parallelogram is a quadrilateral with two pairs of parallel sides, hence it's name. If you were to take a look at the attachment below, you might see the connection.
Rotational Symmetry will make it so that side AB corresponds to CD, respectively AD and CB. The sides will coincide with one another after a 180 degree rotation, so that AB = CD, and AD = CB. Hence, in the same parallelogram, opposite sides are congruent.

Which of the following is a result of shifting a circle with equation (x-2)2 +(y-3)2=25 to the left 2 units ?
A.) Both the x- and y-coordinates of the center of the circle increased by 2
B.) Both the x- and y-coordinate of the center of the circle decreased by 2
C.) The y-coordinate of the center of the circle decreased by 2
D.) The x-coordinate of the center of the circle decreased by 2
Answer:
D.) The x-coordinate of the center of the circle decreased by 2
Step-by-step explanation:
(consult the diagram attached below)
Consider a circle
(x - 2)² + (y - 3)² =25
Where (h, k ) = (2, 3) which is the center of the circle.
When we want to move the circle to the left by 2 units, it also means the the center of the circle will move 2 units to the left.
If center of the circle moves 2 units to the left, it means that the x coordinate of the center of the circle will be decreases by 2 units, while y coordinate will remain the same.
Hence the new coordinate for the center of the circle is (2-2, 3) = (0, 3)
The new equation of circle will be:
(x - 0)² + (y - 3)² =25
(x )² + (y - 3)² =25

The arithmetic mean (average) of four numbers is 85. If the largest of these numbers is 97, find the mean of the remaining three numbers.
Answer: A) = 81
Step-by-step explanation:
Say that the four numbers are a,b,c & 97.
Then a+b+c+97/4 = 85
a+b+c+97=340
a+b+c=243
a+b+c/3 = 81
The average of the remaining three numbers is 81.
What is the average of n numbers a₁, a₂, ..., aₙ?The average of the numbers a₁, a₂, ..., aₙ is calculated as
Average = (a₁ + a₂ + ··· + aₙ) / n.
Given
Average of the four numbers = 85,
The largest of the four numbers is 97.
Find the sum of all the four numbers
Let the four numbers be a, b, c, and d. Then, using their given average,
(a + b + c + d) / 4 = 85
⇒ a + b + c + d = 85 × 4 = 340.
Find the sum of the numbers excluding the largest one
Let the largest number be d. So, d = 97. Then, the sum of the remaining three is
a + b + c = 340 - d = 340 - 97 = 243.
Find the average of the three numbers
Using the above definition average of the remaining three numbers is calculated as
Av(a,b,c) = (a + b + c)/3 = 243 / 3 = 81.
The required average of the remaining three numbers is 81.

Step-by-step explanation:

Your domain is always your x-coordinates, which are the first coordinates in a pair.
Your range is always your y-coordinates, which are the second coordinates in a pair.
When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.

Two jets are flying towards each other from airport that are 1200 km apart. One jet is flying at 250 km.h-1 and the other jet at 350 km.h-1 . If they took off at the same time, how long will it take for the jets to pass each other?
Answer: 2 hours
Step-by-step explanation:
The total velocity at which the planes are approaching each other is 350 + 250 = 600 km/h
Since time = distance/velocity, time = 1200km/ 600 km/h = 2 hours.
