If ∡DAB and ∡DCB are right angles and m∡ABD = 42°, then the measure of arc ACB is 264°.

What is an arc?

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve's arc is a component.

The angles ∡DAB and ∡DCB are right angles.

The measure of ∡ABD = 42°

It can be seen that ∠ABD is inscribed angle of arc AD, so the measure of arc AD is two times the measure of ∠ABD.

AD = 42° × 2 = 84°

It can also be seen that segment DB is diameter of given circle as inscribed angle of diameter is a right angle.

Since segment DB is diameter of given circle, so measure of arc DCB would be equal to half the measure of 360 degrees.

DAB = 360°/2

DAB = 180°

ACB = AD + DCB

ACB = 84° + 180°

ACB = 264°

Therefore, the measure of arc ACB is 264°.

A point (x1, y1) is said to satisfy the inequality ax + by ≤ c if a(x1) + b(y1) ≤ c. The graph of a linear inequality is the set of all points in the plane which satisfy the inequality.

Now, the given equation is 2x + 3y ≥ 6

We can find multiple points (x, y) that satisfy the given inequality. For now, we can take the point (1,2).

To check if (1,2) satisfies the inequality, put x = 1, y = 2 in the inequality.

2 + 6 ≥ 6

8 ≥ 6, which is true.

This line cuts the plane in half. One half contains all points (x, y) with 2x + 3y > 6 and the other half contains all points with 2x + 3y < 6.

To find which half is which, we need only check one point on one side of the line. (if the line does not cut through (0, 0), we can check that point easily.) In this case we find that 2(0) + 3(0) < 6.

Therefore the solution to the inequality 2x + 3y ≥ 6 is the half plane not containing (0, 0) shaded below. We can also represent it with arrows as in the diagram on the right.

Since the region includes the points along the line 2x + 3y = 6, we draw a

solid line. We use a dotted line when we want to indicate strict inequality as in the solution set to 2x + 3y > 6 shown in the diagram.

Thus, this is the boundary line for the given inequality.

The product of the sum and difference of two terms can be found using the distributive property and the FOIL (First, Outer, Inner, Last) method.If you have two terms, A and B, the sum and the difference of these terms can be represented as:

Sum: A + B Difference: A - B

To find the product of the sum and difference, you can multiply the sum and the difference together:

(A + B)(A - B)

Using the distributive property, we can expand the product:

AA - AB + AB - BB

Which is equal to:

A^2 - B^2

This is the difference of squares of the terms.

It's worth noting that this is a very common pattern in algebra, and it's called the difference of squares. It is the product of the sum and difference of two terms.

The value of x from the triangle is x = 44°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of side ∠A = 82°

The measure of side ∠B = 54°

The measure of side ∠C = x°

Now , for a triangle ,

∠A + ∠B + ∠C = 180°

Substituting the values in the equation , we get

82° + 54° + x° = 180°

On simplifying the equation , we get

136° + x° = 180°

Subtracting 136 on both sides of the equation , we get

x = 180° - 136°

x = 44°

Now , for a straight line , the angle in a straight line is 180°

So , x + y = 180°

Substituting the values in the equation , we get

44° + y = 180°

Subtracting 44° on both sides of the equation , we get

y = 136°

Now . the measure of z = measure of y ( alternate interior angles )

So , z = 136°

The equation that relates the number of coins, y, in Janice's collection x months since she started adding to her collection is y = 26 + 5/3 x In the context of this problem, the y-intercept is the initial number of coins that Janice had in her collection while the slope is the rate at which Janice is adding to her collection which is 5/3.

Part A

The equation for the number of coins, y, in Janice's collection x months since she started adding to her collection is the total amount of coins she has and can be expressed as

y = 26 + 5/3 x

where y is the total number of coins, and x is the number of months.

Part B

The y-intercept of the equation is the point where the line of the equation crosses the y-axis. In this case, the y-intercept is the point (0,26) which means that when x = 0, the number of coins in Janice's collection is 26. This is the initial number of coins that Janice had in her collection before she started adding to it.

The slope of the equation is the rate of change of the dependent variable (y) with respect to the independent variable (x). In this case, the slope of the equation is 5/3, which means that for every 3 months that pass, the number of coins in Janice's collection increases by 5. So the slope is the rate at which Janice is adding to her collection.

The problem seems incomplete. It must have been

If Phil received £235 in the ratio 3:5, we can use this information to find out how much money was shared in total.

We know that the ratio of Samantha's share to Phil's share is 3:5.

This means that for every 3 parts of the total money that Samantha gets, Phil gets 5 parts.

We can use this information to set up a proportion:

(Samantha's share) / (Phil's share) = (3) / (5)

We know that Phil's share is £235, so we can substitute that into the proportion:

(Samantha's share) / (235) = (3) / (5)

To find the total amount of money shared, we can cross-multiply and divide:

Samantha's share = (3/5) * 235

Samantha's share = 141

To find the total amount of money shared, we can add the amount Samantha received to the amount Phil received:

141 + 235 = £376

Therefore, £376 was shared in total.

If the discriminant b² - 4ac = 0 for a quadratic equation ax² + bx + c = 0, it means that the nature of roots of the equation has one real and identical (repeated) root.

When the discriminant is equal to zero, the square root of the discriminant will be zero, and the equation will have one solution for x, regardless of the values of a, b and c.

This can be observed in the quadratic formula, where the square root of the discriminant is used to determine the solutions of x. In this case the equation will be reduced to:

x = -b/2a

It's also possible to observe this by factoring the equation, in this case the equation can be factored as (x - r)^2 = 0, where r is the common root. This means that the graph of the equation will touch the x-axis only once.

In summary, when the discriminant b² - 4ac = 0, the roots of the quadratic equation are real and identical (repeated).

The expression C(g(m)) represents the total cost of filling the car's gas tank based on the number of miles driven.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

It is given that the car's gas mileage is 25 miles per gallon, then the number of gallons of gas needed to fill the car's tank can be found by dividing the number of miles driven by the gas mileage.

The expression for this is g(m) = m / 25 where m is the number of miles driven.

The total cost of filling the car's gas tank is represented by the expression C(x) where C is the cost in dollars and x is the number of gallons purchased.

So when g(m) is substituted into C(x), C(g(m)) is obtained which represents the total cost of filling the car's gas tank based on the number of miles driven.

Therefore, this expression is the cost of filling the gas tank given the number of miles driven.
