HELP ME PLEASE I NEED TO FINISH ALGEBRA TODAY ITS URGENT I BEG YOU I DONT HAVE TIME
WARRIOR [948]
#66 Dimensions of matrix: The dimensions of a matrix are
[number of rows (across) x number of columns (up and down)]
There is 1 row and 4 columns, hence the dimensions of [1 x 4]

#71: use factor/label conversion method.
480 minutes    1 hour            480 hours        8 hours
                     * --------------  = --------------  = 
                       60 minutes      60 minutes

#72: common difference is how you get from one number to the next in the sequence. So from 42 to 38, you subtract 4, and the pattern is subtract 4 for the whole sequence. So the common difference <em></em>is -4

#38: The midpoint is the middle of the two coordinates, so imagine when used to find mean by drawing a number line like 1 to 10 and the mean would be 5. What did you do? You added 1 and 10 and divided by 2.
You can use the same method for finding midpoints on the coordinate plane.
The formula for midpoint is <span><span>(<span><span>x1+x</span>2</span>)</span>,<span>(<span><span>y1+y</span>2</span>). So it's (5 + 2) , (8 + 7) which equals (7, 15).

#35: This is the same 3* x^(9*1/5) = 3*x^9/5
Remember square root of a number is the same as that number to the 1/2, and the same with all other roots. The fifth root of x is the same as x to the power of 1/5

#36: This is the same as 36*( x^5*3/2 * y^3*3/2), since you can put the power to each of the numbers almost like the distributive property.
= 36 * (x^15/2 * y^9/2)

Well #20 is <em>extremely</em><em> </em>easy. The solutions are anything that is shaded in the blue

The rightmost question is the same thing as #20. Anything not shaded is not a solution.

</span></span>
#64: Just like you learned in elementary school, the median is the middle number. The middle number is 10<span>

4C. Quintin is using the three different shaped
Sauron [17]

The smallest number of tiles Quintin will need in order to tile  his floor is 20

The given parameters;

  • number of different shapes of tiles available = 3
  • number of each shape = 5
  • area of each square shape tiles, A = 2000 cm²
  • length of the floor, L = 10 m = 1000 cm
  • width of the floor, W = 6 m = 600 cm

To find:

  • the smallest number of tiles Quintin will need in order to tile his floor

Among the three different shapes available, total area of one is calculated as;

A_{one \ square \ type} = 5 \times 2000 \ cm^2 = 10,000 \ cm^2

Area of the floor is calculated as;

A_{floor} = 1000 \ cm \times 600 \ cm = 600,000 \ cm^2

The maximum number tiles needed (this will be possible if only one shape type is used)

maximum \ number= \frac{Area \ of \ floor}{total \ area \ of \ one \ shape \ type} \\\\maximum \ number= \frac{600,000 \ cm^2}{10,000 \ cm^2} \\\\maximum \ number=  60

When all the three different shape types are used we can get the smallest number of tiles needed.

The minimum or smallest number of tiles needed (this will be possible if all the 3 different shapes are used)

3 \times \ smallest \ number  = 60\\\\smallest \ number = \frac{60}{3} \\\\smallest \ number = 20

Thus, the smallest number of tiles Quintin will need in order to tile  his floor is 20

The function g(x) =8(4x) is reflected across the x-axis to create f(x) what is the equation for f(x)
Sveta_85 [38]

Answer:f(x)= -8 (4x) will be the reflected function across x-axis for the function g(x).

Explanation:  since we know that the image or reflection of x along x-axis = -x

That is, when we talk about a function's reflection across any axis then we have to replace variable according to that axis. For example if you have a line x=3 in positive x-axis  then you can also draw a similar line x=-3 in negative x-axis. so, you can say, x=-3 is the reflection of x=3 along x axis.

Similarly, for an another line y=3, y=-3 is a reflection.

thus in the case of g(x) we can find the reflection across x-axis after replacing x by -x.  

we have g(x) =8(4x)  

replace x by -x we get g(-x)= 8(4×-x)= 8(-4x)=-8(4x)

so -8(4x) is the reflection of g(x)

but according to the question f(x) is the reflection of g(x) across x-axis.

Thus, f(x)=-8(4x)
