how many killer whales are there when there are 5 million beluga whales
Answers
We know that the number of og beluga whales varies directly as the number of killer whales, that means that we can write a relation of the form:
[tex]y=kx[/tex]where y is the number of beluga whales, x is the number of killer whales and k is the constant of proportionality.
To answer the question we first need to find k, to do that we plug the values x=23 and y=14 in the equation above and solve for k:
[tex]\begin{gathered} 14=k23 \\ k=\frac{14}{23} \end{gathered}[/tex]Now that we know k the relation is:
[tex]y=\frac{14}{23}x[/tex]Finally to find the number of killer whales if there are 5 millions of beluga whales we plug y=5 in the equation above and solve for x:
[tex]\begin{gathered} 5=\frac{14}{23}x \\ x=\frac{5\cdot23}{14} \\ x=8.21 \end{gathered}[/tex]Therefore when there are 5 millions beluga whales we have 8.21 millions of killer whales.

Answer:
Rewrite the expression 8m^6/4m^9 using the rules of exponents
Step-by-step explanation:
8 ÷ 4 = 2
m^6 ÷ m^9
exponent rule in a division problem is you subtract them so...
6 - 9 = -3
you can't have a negative exponent so it would be 2 over m^3
If you have a negative exponent the rule is "flip it" meaning you flip the sign but when you do that it becomes a fraction. so... 2/m^3
In your own words, describe the location of each point on a coordinate plane. Be specific. 1. (0,4)2.(2,5) 3.(-3, 6)
Answers
Locations on the coordinate plane are described as ordered pairs. An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair)
1. Point ( 0, 4)
The coordinate of ( 0, 4) is on the y-axis, because x = 0 and y = 4.
The point ( 0, 4) is on the y-axis at y = 4
2. Point ( 2, 5 )
Starting from the origin, go along the x-axis 2 units in a positive direction (right) and along the y-axis 5 units in a positive direction (up).
3. P( -3 , 4 )

The sum of the given matrices is not possible to calculate as the order of both the matrix are different.
To add two matrices both matrices must be of the same order.
[3 -8] is of order 1 × 2
[4 -5 -6] is of order 1 × 3
Since the two matrices are of different orders it is not possible for the two matrices to be added.
Although direct sum or Kronecker sum could be used to add the matrices but the correct symbol for them is not used.
Hence the required result is impossible .
A matrix, also spelled "matrices," is a rectangular table or array of characters that are arranged in rows and columns to represent a mathematical object or a property of one.
Matrix representations of linear mappings in linear algebra allow for explicit computations. Because of this, matrices are studied extensively in linear algebra, and most properties and actions of abstract discrete mathematics may be explained in terms of matrices.

find an equation of the line passing through the pair points. write the equation in the form ax+by=c (-7,5),(-8,-9)
Answers
Given the pair of coordinates;
[tex]\begin{gathered} (-7,5) \\ (-8,-9) \end{gathered}[/tex]We would begin by first calculating the slope of the line.
This is given by the formula;
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]The variables are as follows;
[tex]\begin{gathered} (x_1,y_1)=(-7,5) \\ (x_2,y_2)=(-8,-9) \end{gathered}[/tex]We will now substitute these into the formula for finding the slope as shown below;
[tex]\begin{gathered} m=\frac{(-9-5)}{(-8-\lbrack-7)} \\ \end{gathered}[/tex][tex]\begin{gathered} m=\frac{-14}{-8+7} \\ \end{gathered}[/tex][tex]\begin{gathered} m=\frac{-14}{-1} \\ m=14 \end{gathered}[/tex]The slope of this line equals 14. We shall use this value along with a set of coordinates to now determine the y-intercept.
Using the slope-intercept form of the equation we would have;
[tex]y=mx+b[/tex]We would now substitute for the following variables;
[tex]\begin{gathered} m=14 \\ (x,y)=(-7,5) \end{gathered}[/tex][tex]5=14(-7)+b[/tex][tex]5=-98+b[/tex]Add 98 to both sides of the equation;
[tex]103=b[/tex]We now have the values of m, and b.The equation in "slope-intercept form" would be;
[tex]y=14x+103[/tex]To convert this linear equation into the standard form which is;
[tex]Ax+By=C[/tex]We would move the term with variable x to the left side of the equation;
[tex]\begin{gathered} y=14x+103 \\ \text{Subtract 14x from both sides;} \\ y-14x=103 \end{gathered}[/tex]We can now re-write and we'll have;

Answers
First, write the factors 996 and 32 in the following arrangement:
Next, take the last digit of 32, which is 2, and multiply it by 996. To do so, first, multiply 2 times 6:
[tex]2\times6=12[/tex]Write the units below the column of the 6, and save the remaining 10 units to be added in the next step.
Next, multiply 2 by the next digit from right to left of 996, which is 9:
[tex]2\times9=18[/tex]Add 1 to the result, since it was a remainder from the last operation:
[tex]18+1=19[/tex]Write a 9 below the second colum, and save the remaining 10 units to be added on the next step.
Repeat the procedure for the third digit of 996 from right to left, which is 9.
[tex]2\times9=18[/tex][tex]18+1=19[/tex]Since there are no more digits from the upper number, write 19 below the third colum.
Now, repeat the procedure with the next digit from the lower number (32), which is 3. Write the result one place shifted to the left.
[tex]3\times6=18[/tex]Next, move to the next digit from right to left of the upper number, which is 9:
[tex]3\times9=27[/tex][tex]27+1=28[/tex]Next, move to the next and last digit from right to left of the upper number, which is 9:
[tex]\begin{gathered} 3\times9=27 \\ 27+2=29 \end{gathered}[/tex]Fill the blank space at the right of the last row with a 0 and add both numbers:

Explanation: We are given two points, P1 is vertex and P2 is another point on the parabola:
[tex]\begin{gathered} P_1(2,-4) \\ P_2(3,-1) \end{gathered}[/tex]The general form of the equation of a parabola is:
[tex]y(x)=A(x\pm B)^2+C[/tex]Where A is the Coefficient of the parabola function which is responsible for compression and stretch, likewise B is responsible for the translation along the x-axis and C is responsible for translation along the y-axis.
We know that our function is translated 2 units towards the right and 4 units downwards:
Therefore:
[tex]\begin{gathered} B=-2 \\ C=-4 \end{gathered}[/tex]And this turns the parabola equation into:
