i. f.g(x)

For the functions, f(x) = −x+2, and g(x)=5x²,

b) g(f(x)) = 5x² -20x + 20
c) f∘(g(x))² = 25x⁴
d) g(x - 1) = 5x² - 10x + 5
Here, the functions are: f(x) = −x+2, and g(x)=5x²
a) f∘g(x)
We know that composite function f∘g(x) means f(g(x))
For function f(x) substitute x = g(x)
i.e., f(g(x)) = -(g(x)) + 2
= -(5x²) +2
= 5x² + 2
b) g(f(x))
For function g(x) substitute x = f(x)
i.e., g(f(x)) = 5x²
= 5(-x + 2)²
= 5(x² -4x + 4)
= 5x² -20x + 20
c) f∘(g(x))²
First we find the (g(x))²= (5x²)²
= 25x⁴
Now the composite function f∘(g(x))² would be,
f∘(g(x))² = f((g(x))²)
= -(g(x))²+ 2
= -(g(x))² + 2
d) g(x - 1)
Substitute x = x -1 in function g(x)
g(x - 1) = 5(x - 1)²
= 5(x² - 2x + 1)
= 5x² - 10x + 5

Find the probability of drawing a green, then yellow, with replacement.
A bag has 4 green blocks, 6 red blocks, 7 blue and 3 yellow.
The probability of drawing a green block followed by a yellow block with replacement is 0.03, or 3%.
What is probability?The probability of an event is calculated by dividing the total number of possible outcomes by the number of possible outcomes.
The likelihood of drawing a green block on the main draw is:
P(green) = (number of green blocks) / (total number of blocks)
P(green) = 4 / (4 + 6 + 7 + 3)
P(green) = 4 / 20
P(green) = 0.2
Since the blocks are replaced after each draw, the probability of drawing a yellow block on the second draw is still:
P(yellow) = (number of yellow blocks) / (total number of blocks)
P(yellow) = 3 / (4 + 6 + 7 + 3)
P(yellow) = 3 / 20
P(yellow) = 0.15
To find the probability of both events happening, we multiply the probabilities:
P(green, then yellow) = P(green) * P(yellow)
P(green, then yellow) = 0.2 * 0.15
P(green, then yellow) = 0.03
As a result, replacing a yellow block with a green one has a chance of 0.03, or 3%, being drawn.

ABC is a right angled triangle. if B = 90°, AC = 96 cm, C = 30°. Find AB?
Answer:
We can use trigonometry to find AB.
First, we can use the fact that the sum of the angles in a triangle is 180° to find angle A:
A + B + C = 180°
A + 90° + 30° = 180°
A = 60°
Now, we can use the sine function to find AB:
sin A = opposite/hypotenuse
sin 60° = AB/96
AB = 96 * sin 60°
AB = 96 * √3/2
AB = 48√3
Therefore, AB is approximately 83.14 cm (rounded to two decimal places).

The compliment of an angle is three times the measurement of the angle. Find the measurement of the larger angle
The greater angle has a 67.5° degree measurement. When two angles' measurements add up to 90°degrees, they are said to be complimentary.
How to calculate the larger angle?Call that angle we're looking for "x" for convenience.
The degree that, if added to x, makes x equal 90° degrees is known as the compliment of x.
We now know that 3x, or 3 times x, is the compliment of x.
With this knowledge, we can construct the following equation:
x + 3x = 90°
combining comparable equations;
4x = 90°
x = 22.5°, when both sides are divided by 4.
As a result,
3x = 3(22.5°) = 67.5° degrees is the measurement of the greater angle, which is the complement of x.

Find the surface area of the triangular prism. The base of the prism is an isosceles triangle.
The answer of the given question based on the Rectangular prism is , the surface area of the given triangular prism is 3360 cm².
What is Rectangular prism?A rectangular prism is a three-dimensional geometric shape with six rectangular faces. It is also known as rectangular parallelepiped or cuboid. A rectangular prism has a length (l), width (w), and height (h) and the formula for the volume of a rectangular prism is given as V = l * w * h.
To find the surface area of a triangular prism, we need to add up the areas of all of its faces. A triangular prism has two identical triangular bases and three rectangular faces.
First, let's find the area of the triangular base. We know that it is an isosceles triangle with a perpendicular height of 35 cm and base of 24 cm, and the length of the two equal sides is 37 cm. We can use the formula for the area of a triangle:
Area of base = (1/2) * base * height
Area of base = (1/2) * 24 cm * 35 cm
Area of base = 420 cm²
Since there are two identical bases, we can multiply this by 2 to get the total area of the triangular bases:
Total area of bases = 2 * 420 cm²
Total area of bases = 840 cm²
Now, let's find the area of the three rectangular faces. We know that the height of the prism is 35 cm, and the length of each rectangular face is equal to the base of the triangular base, which is 24 cm. To find the width of each rectangular face, we need to use the Pythagorean theorem to find the length of the altitude of the triangular base:
a² + b² = c²
where a and b are the two equal sides of the triangular base, and c is the base.
Substituting the given values, we get:
a² + b² = c²
37² + 12² = c²
1369 + 144 = c²
c² = 1513
c = √1513
c = 38.95 cm
Therefore, the altitude of the triangular base is approximately 35 cm, and we can use this value as the width of each rectangular face. So, area of each rectangular face is given:
Area of each rectangular face = length*width
Area of each rectangular face = 24 cm * 35 cm
Area of each rectangular face = 840 cm²
Since there are three identical rectangular faces, we can multiply this by 3 to get the total area of the rectangular faces:
Total area of rectangular faces = 3 * 840 cm²
Total area of rectangular faces = 2520 cm²
Finally, we can find the total surface area of the prism by adding the areas of the two triangular bases and the three rectangular faces:
Total surface area = Total area of bases + Total area of rectangular faces
Total surface area = 840 cm² + 2520 cm²
Total surface area = 3360 cm²
Therefore, the surface area of the given triangular prism is 3360 cm².

The value of (a) in given triangle is approximately 7.44 cm.
What do you mean by triangle?A triangle is a three-sided polygon consisting of three sides and three vertices. The most important property of a triangle is that the sum of its interior angles is 180 degrees.
Let ΔABC is a triangle
Given ∠ B = 75°
∠ C = 31.8°
AB = 12cm
AC = 22cm
find BC = ?
We can use the law of cosines to solve for BC:
BC² = AB² + AC² – 2(AB)(AC)cos(B)
We know that angle B = 75 degrees, so we can substitute:
BC² = 12² + 22² - 2(12)(22)cos(75)
Evaluating cos(75) with a calculator, we get:
BC² ≈ 144 + 484 - 572.59
BC² ≈ 55.41
Taking the square root of both sides gives us:
BC ≈ 7.44

Billy has x pounds. Liam has twice as much money as billy. Nicola has 3 times as much money as liam. The total amount of money they have is £180 pounds.
A) form an expression in terms of x and find out how much money they have.
Answer:
Billy has £20, Liam has £40, and Nicola has £120. The total amount of money they have is £180, as given in the problem.
Step-by-step explanation:
Let's start by defining the variables:
Billy's money: x pounds
Liam's money: 2x pounds (twice as much as Billy)
Nicola's money: 3(2x) = 6x pounds (three times as much as Liam)
The total amount of money they have is £180, so we can write an equation:
x + 2x + 6x = 180
Simplifying the left side of the equation:
9x = 180
Solving for x:
x = 20
Now we can find out how much money each person has:
Billy: x = 20 pounds
Liam: 2x = 2(20) = 40 pounds
Nicola: 6x = 6(20) = 120 pounds

The top three prices for works of art sold at auction in 2013 totaled $308.0 million. These three works of art were a sculpture, a painting, and a photograph. The selling price of the painting was $49.4 million more than that of the photograph. Together, the painting and the photograph sold for $24.4 million more than the sculpture. What was the selling price of each work?
The selling prices of the sculpture, painting, and photograph were 166.5 million, 107.0 million, and 57.6 million respectively.
How to Determine the Selling Price?Let's call the selling prices of the sculpture, painting, and photograph as S, P, and Ph respectively.
From the first sentence, we know that:
S + P + Ph = 308.0 million
From the second sentence, we know that:
P = Ph + 49.4 million
And from the third sentence, we know that:
P + Ph = S + 24.4 million
Now we can substitute the second equation into the third equation:
(Ph + 49.4 million) + Ph = S + 24.4 million
Simplifying:
2Ph + 49.4 million = S + 24.4 million
2Ph = S - 25 million
Substituting this into the first equation:
S + P + Ph = 308.0 million
S + (Ph + 49.4 million) + Ph = 308.0 million
2Ph + S = 258.6 million
Now we can substitute the equation we derived earlier:
S + 2Ph - 49.4 million = 258.6 million
S + 2Ph = 308.0 million
Substituting 2Ph = S - 25 million:
S + S - 25 million = 308.0 million
2S = 333.0 million
S = 166.5 million
Now we can use this value to find P and Ph:
P = Ph + 49.4 million
P + Ph = S + 24.4 million
Substituting S = 166.5 million in both equations:
P + Ph = 190.9 million
P = Ph + 49.4 million
Solving these two equations simultaneously:
Ph = 57.6 million
P = 107.0 million
