Answer:

a)  32° Celsius

b)  C = m/3 + 4

c) 30 chirps

d) m = 3C - 12

This would be the equation needed to find the number of chirps as a function of temperature

Step-by-step explanation:

Part a.

Since there are 84 chirps in 25 seconds
we get temperature, C = 84/3 + 4 = 28 + 4 = 32° Celsius

part b.
Equation is
C = m/3 + 4

Part c.

We have C = 14

Therefore

14 = m/3 + 4

Multiply throughout by 3

==> 3 x 14 = 3 x m/3 + 3 x 4

==> 42 = m + 12

Subtract 12:

42 - 12 = m30 = m

or m = 30 chirps

part d.

Inverse of the function C = m/3 + 4 is m expresses as a function of C

C = m/3 + 4

Multiply by 3 both sides:
3C = m + 12

3C - 12 = m

or m = 3C - 12

This would be the equation needed to find the number of chirps as a function of temperature

A. The thickness of the rectangular sheet of sugar paste is 1/5 cm.

B. The volume of the remaining pastry can be expressed as approximately 45.84 cm³.

The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.

The volume of a cuboid is length × breadth× height

A) The volume of the cuboid pack of sugar paste is 5 cm x 8 cm x 9 cm = 360 cm³.

To find the thickness of the rolled-out rectangular sheet, we need to divide the volume of the pack by the area of the rectangular sheet:

thickness = volume/area

thickness = 360 cm³ / (30 cm x 60 cm)

thickness = 360 cm³ / 1800 cm²

thickness = 1/5 cm

So the thickness of the rectangular sheet of sugar paste is 1/5 cm.

B) The two circular pieces of pastry each have a diameter of 25 cm and thus a radius of 25/2 = 12.5 cm.

The volume of each circular piece of pastry can be calculated as:

V = π × (radius)² × thickness

V = π × (12.5 cm)² × 1/5 cm

V = π × 156.25 × 1/5 cm³

V = 50 × π cm³

Since Mary cuts out two circular pieces, the total volume of pastry that she removes is 2 x 50 x π cm³. The remaining volume of pastry is the original volume of the pack minus the volume of the two circular pieces:

Volume remaining = 360 cm³ - 2 × 50 × π cm³ = 45.84 cm³

The volume of the remaining pastry can be expressed as approximately 45.84 cm³.

You spend 480 minutes per day at school. We will assume that you go to school for 5 days per week.

480 minutes × 5 days = 2,400 minutes per week

There are 4 weeks in a month, so we will multiply the minutes per week by 4 weeks to get the monthly time spent in school.

2,400 minutes per week × 4 weeks = 9,600 minutes per month

You are in school for 10 months, so we will multiply the minutes per month by 10.

9,600 minutes per month × 10 months = 96,000 minutes in school

Now, we will divide the time in school by the number of minutes in school per day.

96,000 minutes in school ÷ 480 minutes per day = 200 days in school

Answer: 96,000 hours or 200 days

Using combinatorial reasoning, the expression of[tex](x y)5 is x^5y^5 + 5x^4y^6 + 10x^3y^7 + 10x^2y^8 + 5xy^9 + y^10[/tex]. Using the binomial theorem, it is[tex]1x^5 + 5x^4y + 10x^3y^2 + 10x^2y^3 + 5xy^4 + y^5[/tex].

a) Combinatorial reasoning involves breaking the expression down into different combinations of x and y, and then multiplying each combination. In this case, (x y)5 can be broken down into

[tex]x^5y^0 + x^4y^1 + x^3y^2 + x^2y^3 + x^1y^4 + x^0y^5[/tex],

and the coefficient of each term is the number of ways that combination can be derived from the expression. For example, there are 5 ways to arrange the combination [tex]x^4y^1[/tex], so its coefficient is 5. When the coefficients are multiplied with the combinations, they become

[tex]5x^4y^1 + 10x^3y^2 + 10x^2y^3 + 5xy^4 + y^5[/tex],

which is the expansion of (x y)5.

b) The binomial theorem states that for any expression of the form [tex](x + y)^n[/tex], the expansion can be found by multiplying the term[tex]x^n[/tex]with the coefficient of each term in Pascal’s triangle. For example, for[tex](x + y)^5[/tex], the coefficient of[tex]x^5[/tex] is 1, the coefficient of[tex]x^4y[/tex]is 5, the coefficient of[tex]x^3y^2[/tex]is 10, the coefficient of [tex]x^2y^3[/tex]is 10, the coefficient of[tex]x^1y^4 is 5[/tex], and the coefficient of[tex]y^5[/tex]is 1.

As a result, the coordinate of the picture of point B (4, 9) under dilation with the origin as the center and a scale factor of 2 is (8, 18).

Coordinates are a pair of integers that are used to locate a point or object in a two-dimensional plane. A point's location on a 2D plane is defined by two integers called the x-coordinate and the y-coordinate. The distance between two points is known as the x-coordinate, or abscissa, while the distance between two points is known as the y-coordinate, or ordinate. Point (3, 2), for example, is three units distant from the positive y-axis and two units away from the positive x-axis.

Here,

A dilation with center at the origin and scale factor of 2 will stretch or shrink the distances from the origin by a factor of 2. If the given point B is (4,9), its image under the dilation will be:

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Answer: 13

Step-by-step explanation: The two numbers are 967 and 445 making a=4 and b=9. We know a+b= 9+4 which is 13. For starters, you add the last digits of b67 and aa5 so 7+5=12 which is why the four digit number ends in two. When adding, the one from 12 would carry so the second to last digit on the four digit number would have to be 11. To get eleven you would add 7 and 4. The seven comes from the second digit in the b67 number including the one that came from 7+5=12. Now we know a=4. Knowing this now aa5= 445 and 1a12= 1412. We can now substract 445 from 1412 to get 967. b67= 967. To check 967+445=1412.

The area of the shaded region is [ (36 * √3)/4 - 3 * (9 * √3)/4 ] square units = (36 * √3)/4 - 27 * √3/4 square units = 9 * √3/4 square units.

The area of a triangle can be found using the following formula:

Area = (base * height) / 2

The area of the shaded region can be found by subtracting the sum of the areas of three small equilateral triangles from the area of the original equilateral triangle.

Each of the small equilateral triangles has side length 3, since it is half the length of the original triangle's sides. The area of each small triangle is (3^2 * √3)/4 = (9 * √3)/4 square units.

The area of the original equilateral triangle is (6^2 * √3)/4 = (36 * √3)/4 square units.

Hence, the area of the shaded region is [ (36 * √3)/4 - 3 * (9 * √3)/4 ] square units = (36 * √3)/4 - 27 * √3/4 square units = 9 * √3/4 square units.
