The graph of g(x) = (x - 2)^3 + 7 is a transformation of the parent function f(x) = x^3.
The parent function f(x) = x^3 has a shape that is symmetrical about the origin and increases as x moves away from the origin. The graph of g(x) = (x - 2)^3 + 7 is also symmetrical about the origin, but it has been translated 2 units to the right and 7 units up from the parent function.
So, the graph of g(x) = (x - 2)^3 + 7 is similar in shape to the parent function f(x) = x^3, but it is shifted to the right and up on the coordinate plane.

the weight of reports produced in a certain department has a normal distribution with mean 60g and standard deviation 12g. what is the probability that the next report will weigh less than 45g?
The probability that the next report will weigh less than 45g is approximately 0.1056 or 10.56%. We can use the standard normal distribution to find the probability that the next report will weigh less than 45g.
z = (x - mu) / sigma
where z is the standard score, x is the value we want to standardize (45g), mu is the mean (60g), and sigma is the standard deviation (12g).
Substituting the given values, we get:
z = (45 - 60) / 12
z = -1.25
Next, we use a standard normal distribution table (or a calculator) to find the cumulative probability of z being less than -1.25. This gives us:
P(z < -1.25) = 0.1056
Therefore, the probability that the next report will weigh less than 45g is approximately 0.1056 or 10.56%.

8. A In rectangle ABCD, AC and BD are diagonals. If m/1 = 55, find ABD.
The value of m∠ABD is equals to 125 degrees.
What is a rectangle ?
Rectangle can be defined in which opposite sides are equal.
AC and BD are diagonals of the rectangle ABCD.
Angle ABD is adjacent to angle 1 and angle ABO, where O is the intersection of diagonals AC and BD.
We know that m∠1 = 55, and we can find m∠ABO using the fact that the diagonals of a rectangle bisect each other. Since angle AOB is opposite to side AB, which is congruent to side CD, we have:
m∠ABO = 180 - m∠AOB
= 180 - (180 - m∠1) / 2
= 180 - (180 - 55) / 2
= 62.5
Therefore, we can find m∠ABD by adding m∠ABO and m∠DBO, where DBO is congruent to ABO:
m∠ABD = m∠ABO + m∠DBO
= m∠ABO + m∠ABO
= 2m∠ABO
= 2(62.5)
= 125

the measure of one interior angle of a parallelogram is 0.25 times the measure of another angle.
The interior angle of a parallelogram is proportional to the measure of another angle with a ratio of 0.25:1.
A parallelogram is a four-sided flat shape that has opposite sides that are parallel and equal in length. The sum of the interior angles of a parallelogram is equal to 360 degrees. If the measure of one interior angle is 0.25 times the measure of another angle, this means that there is a proportionate relationship between the two angles. To find the measure of the second angle, we can use the formula:
Angle 2 = (Angle 1) / 0.25
For example, if Angle 1 is 100 degrees, then Angle 2 is 100 / 0.25 = 400 degrees. This means that if one angle measures 100 degrees, the other angle measures 400 degrees. The sum of the two angles is 500 degrees, which is still less than the total sum of interior angles in a parallelogram, which is 360 degrees.

a box contains 12 balls of which some are red in colour. if 6 more red balls are put in the box and a ball is drawn at random the probability of drawing a red ball doubles than what it was before. find the number of red balls in the bag.
We are told that the probability of drawing a red ball doubles when an extra 6 red balls are added.
Let's assume that there are initially "x" red balls in the box. This means that there are (12 - x) non-red balls in the box.
When 6 more red balls are added, the total number of red balls becomes (x + 6), and the total number of balls in the box becomes (12 + 6) = 18.
We are told that the probability of drawing a red ball doubles when an extra 6 red balls are added. This means that the probability of drawing a red ball before the extra balls were added was:
P(red) = x / 12
And the probability of drawing a red ball after the extra balls were added is:
P(red) = (x + 6) / 18
We are also told that the second probability is twice the first:
(x + 6) / 18 = 2 * (x / 12)
Simplifying this equation, we get:
(x + 6) / 9 = x / 6
Multiplying both sides by 18, we get:
2(x + 6) = 3x
Expanding the left-hand side, we get:
2x + 12 = 3x
Subtracting 2x from both sides, we get:
12 = x
Therefore, there are initially 12 red balls in the box.

what distance does the tip of the minute hand on a clock travel in 11 minutes if the minute hand is 23 cm long?
The tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.
What is Circle?
A circle is a two-dimensional geometric shape that is defined as the set of all points in a plane that are a fixed distance away from a given point, called the center of the circle. This distance is known as the radius of the circle.
A circle can also be defined as the locus of a point that moves in a plane in such a way that its distance from a fixed point is constant. The constant distance is the radius of the circle.
The minute hand on a clock makes a full rotation in 60 minutes, which means it travels the circumference of a circle with a radius of 23 cm in 60 minutes. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14.
Therefore, the circumference of the circle traced by the tip of the minute hand is:
C = 2πr = 2 × 3.14 × 23 cm ≈ 144.44 cm
To find out how far the minute hand travels in 11 minutes, we need to calculate what fraction of the circumference it covers in that time. Since 11 minutes is about 18.3% of an hour (60 minutes), the minute hand travels 18.3% of the circumference of the circle in that time:
Distance traveled = 0.183 × 144.44 cm ≈ 26.4 cm
Therefore, the tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.

The total number of cows is given by the equation c = 182 cows and the total number of legs of cows is n = 728 legs
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The total number of cows and goats = 452
So , c + g = 452 be equation (1)
And , ( 5/7 )c = ( 13/27 )g
On simplifying the equation , we get
c = ( 13 x 7 ) / ( 5 x 27 ) g
c = ( 91/135 )g be equation (2)
Substituting the value of c in equation (1) , we get
( 91 / 135 ) g + g = 452
On further simplification , we get
( 91 + 135 ) / 135 g = 452
( 226 / 135 ) g = 452
Divide by 226 on both sides of the equation , we get
( 1/135 )g = 2
Multiply by 135 on both sides of the equation , we get

Themba lends 12 000 to his friend to buy a car he requires the loan to be repaid after five years with a payment of 22 109,22 . what was the compound interest rate that he charged
The compound interest rate charged is given as follows:
13% per year.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
P is the principal, which is the value of deposit/loan/....r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.The parameters for this problem are given as follows:
P = 12000, A(t) = 22109.22, n = 1, t = 5.
Hence the interest rate is obtained as follows:
22109.22 = 12000(1 + r)^5
(1 + r)^5 = 22109.22/12000
1 + r = (22109.22/12000)^(1/5)
1 + r = 1.13
r = 1.13 - 1
r = 0.13.
