If f(x) = 5x2 - 3 and g(x) = x2 - 4x - 8, find (f - g)(x).
O A. (- 9)(x) = 4x2 - 4x - 5
O B. (f- g)(x) = 4x2 + 4x + 5
O C. (f- g)(x) = 2x2 - 11
O D. (1-9)(x) = 6x2 - 4x - 11
Answers
Answer:
The answer is option B.
f(x) = 5x² - 3
g(x) = x² - 4x - 8
(f - g)(x) = 5x² - 3 - ( x² - 4x - 8)
= 5x² - 3 - x² + 4x + 8
= 4x² + 4x + 5 option B
Hope this helps.

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

Answers
The area is 198.5cm sq
The shape can be divided into a circle of
5cm radius
as diameter is 10cm
radius = d/2
and a rectangle of 12×10 cm dimensions
length is 22-( 2×5) 12cm
and breadth is 10cm
The area of the circle is pi(r square)
which is 3.14×25
= 78.5 cm sq
The area of the rectangle is l×b
which is 12×10
= 120 cm sq
The total area is thus
area of rectangle plus area of circle
which is 198.5cm sq

The number that is four greater than three times its additive inverse
is - 3n + 4.
What are additive and multiplicative inverses?A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
Let the unknown number be 'n' so its additive inverse is '-n'.
So, the number that is four greater than three times its additive inverse is,
Three times of additive inverse is -3n.
Now the number is 4 greater than 3 times its additive inverse which is
= - 3n + 4.
