Answer:

∠ ADE = 55° , ∠ ACE = 32.5° , ∠ BAD = 22.5°

Step-by-step explanation:

the measure of the inscribed angle ADE is half the measure of its intercepted arc AE , then

∠ ADE = [tex]\frac{1}{2}[/tex] × 110° = 55°

---------------------------------

the measure of the secant- secant angle ACE is half the difference of the measures of the intercepted arcs , that is

∠ ACE = [tex]\frac{1}{2}[/tex] (AE - BD) = [tex]\frac{1}{2}[/tex] (110 - 45)° = [tex]\frac{1}{2}[/tex] × 65° = 32.5°

-----------------------------------------

the measure of the inscribed angle BAD is half the measure of its intercepted arc BD , that is

∠ BAD = [tex]\frac{1}{2}[/tex] × 45° = 22.5°

Is not possible to define a radius  nor a diameter in a trapezium.

Radius and diameter are two measures defined for circles.

Radius is the distance between the center and any point in the circumference, and the diameter is the distance between two opposite points in the circumference (so it does not need to be 3D to have radius/diameter).

At the same time, a trapezium is not a circle, is a quadrilateral, so it can't have any of these.

To get the area use the formula:

Area = (base1 + base2)*height / 2

a.  The investment to double in value take about 14 years for the funding to double in value.

b.  The genuine time it will take for the funding to double in fee is about 13.86 years.

(a) To estimate the time it takes for an funding to double in cost the use of the rule of 70, we want to decide the increase rate. In this case, the increase price is given as 5% per 12 months compounded continuously.

Using the rule of 70, we can calculate the estimated doubling time:

Time to double ≈ 70 / boom rate

Time to double ≈ 70 / 5

Simplifying, we have:

Time to double ≈ 14 years

Therefore, it would take about 14 years for the funding to double in value.

(b) To decide the genuine time it will take for the funding to double in value, we can use the formulation for non-stop compounding:

Doubling time (exact) = ln(2) / (ln(1 + r))

where r is the increase fee as a decimal.

In this case, the increase charge is 5% per year, or 0.05 as a decimal.

Doubling time (exact) = ln(2) / (ln(1 + 0.05))

Doubling time (exact) ≈ 13.86 years (rounded to two decimal places)

Therefore, the genuine time it will take for the funding to double in fee is about 13.86 years.

Both triangles in the image are similar based on the AAA similarity theorem. The radius of the circle B is therefore calculated as: AB = 12.

Similar triangles are geometric figures that have the same shape but may differ in size. They have corresponding angles that are equal and corresponding sides that are in proportion to each other.

Since AD serves as a common tangent, angle BAE is equal to 90 degrees, which is also equal to angle CDE due to being opposite angles.

By the Angle-Angle-Angle (AAA) similarity criterion, triangles ABE and DCE are similar.

Therefore:

AB/EA = DC/ED

Substitute:

AB/18 = 4/6

Cross multiply:

AB = 18 * 4/6

AB = 12

Step-by-step explanation:

When calculating volume, units of measurement are cubed. When calculating surface area, units of measurement are squared.

Further explanation:

Let's say you are finding the area of a rectangle. The length is 5in and the width is 7 in.

since you know l*w is area, you need to multiply 5in and 7in. 5*7=35 and then the two units of measurement, in*in=in^2 so 5in*7in=35in^2. the unit is squared not cubed.

The units of measurement for surface area are always SQUARED. Hence the correct answer is FALSE.

In 2-D, the total space covered by any two-dimensional figure is called Area while if we talk about 3-D, the total area of all the outer surfaces when added, sums up to form the Surface Area. Hence, the surface area is the multiplication of any two of the physical quantities.

For example,

Area of a square=(side x side)

                           =(metre x metre) or (cm x cm) [in terms of units]

                           = [tex]metre^{2}[/tex] or [tex]cm^{2}[/tex]

Similarly,

Surface Area of cube=6x(side x side)  [summation of the area of 6 faces of cube]

                                   =(metre x metre) or (cm x cm) [in terms of units]

                                    = [tex]metre^{2}[/tex] or [tex]cm^{2}[/tex]  (again)

Therefore, The units of measurement for the surface area are always SQUARED. Hence the correct answer is FALSE.

When talking of volume, since volume is the amount of space taken by any object or any 3-Dimensional body, the units of measurement of Volume are always cubed. For example, [tex]metre^{3}[/tex] or [tex]cm^{3}[/tex].

The equation of the line perpendicular to the line with a slope of 1/13 and passing through the point (-1, 3) is y = -13x - 10.

To find the equation of a line perpendicular to a line with a slope of 1/13 and passing through the point (-1, 3), we need to determine the slope of the perpendicular line.

The slope of a line perpendicular to another line can be found by taking the negative reciprocal of the given slope. The negative reciprocal of 1/13 is -13/1, or simply -13.

Now that we have the slope (-13) and a point (-1, 3) that the line passes through, we can use the point-slope form of a linear equation to find the equation of the perpendicular line.

The point-slope form is given by:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the given point and m is the slope.

Substituting the values (-1, 3) and -13 into the point-slope form, we get:

y - 3 = -13(x - (-1))

Simplifying:

y - 3 = -13(x + 1)

Expanding the equation:

y - 3 = -13x - 13

To convert the equation to slope-intercept form (y = mx + b), we can isolate y:

y = -13x - 13 + 3

y = -13x - 10

Therefore, the equation of the line perpendicular to the line with a slope of 1/13 and passing through the point (-1, 3) is y = -13x - 10.

A polynomial is a mathematical expression which have a sum of powers in one or more variables with coefficients. The highest power of the variable in a polynomial is called its degree.

We shall divide the polynomial x³ + 3x² - 8x + 140 by x + 7 as follows;

x³ divided by x equals x²

x + 7 multiplied by x² equals x³ + 7x²

subtract x³ - x² from x³ + 3x² - 8x + 140 will result to -4x² - 8x + 140

-4x² divided by x equals -4x

x + 7 multiplied by -4x equals -4x² - 28x

subtract -4x² - 28x from -4x² - 8x + 140 will result to 20x + 140

20x divided by x equals 20

x + 7 multiplied by 20 equals 20x + 140

subtract 20x + 140 from 20x + 140 will result to a remainder 0

Therefore, the polynomial P(x) = x³ + 3x² - 8x + 140 divided by (x + 7), will give a quotient of x² - 3x + 2 and a remainder of 0 using the long division, we can write P(x) = (x + 7)(x² - 4x + 20) + 0

Answer:

Samuel = 21 orders

Nicole = 31 orders

Miguel = 63 orders

Step-by-step explanation:

Let N represent Nicole's orders, M represents Miguel's orders, and S represent Samuel's orders.

We know that the sum of their tree orders equals 115 as

N + M + S = 115

Since Miguel served 3 times as many orders as Samuel, we know that

M = 3S.

Since Nicole served 10 more orders than Samuel, we know that

N = S + 10

Samuel's Orders:

Now we can plug in 3S for M and S + 10 for N to find S, the number of Samuel's orders:

S + 10 + 3S + S = 115

5S + 10 = 115

5S = 105

S = 21

Thus, Samuel served 21 orders.

Nicole's Orders:

Now we can plug in 21 for S in N = S + 10 to determine how many orders Nicole served:

N = 21 + 10

N = 31

Thus, Nicole served 31 orders.

Miguel's Orders:

Now we plug in 19 for S in M  = 3S to determine how many orders Miguel served:

M = 3(21)

M = 63

Thus, Miguel served 63 orders.

The value of a and b in the given complex expression is  1/10 and -1/10 respectively.

This is a problem related to the complex numbers. The complex numbers has a general form of (a+bi) where 'i' is the imaginary number or √-1. The part without an 'i' is called Real Part and the part with an 'i' is called Imaginary Part.

(2i/2+i) - 3i/(3+i) = a + bi

{ 2i(3+i) - 3i(2+i) }/ (2 + i)(3 + i) = a+bi

6i + 2i² - 6i - 3i² / (2 + i)(3 + i) = a+bi

(-2 + 3) / (6 + 5i - 1) = s+bi

1 / (5 + 5i) = a+bi

Now we multiply top and bottom by 5 - 5i :

5 - 5i / (5 + 5i)(5 - 5i) = a+bi

5 - 5i / 25 -25i² = a+bi

5 - 5i / 50 = a+bi

1/10 - 1/10i = a+bi

On comparing the real and imaginary part on the both sides:

a= 1/10 , b= -1/10.

,Alice, Raul, and Maria can make 1 whole batch of a dozen cookies together using the ingredients they brought.

To determine how many whole batches of a dozen cookies they can make, we need to compare the amount of flour and butter they have with the required amounts for each batch of cookies.

Let's calculate the total amount of flour and butter each student brought:

Alice:

Flour: 2 cups

Butter: 1/4 cup

Maria:

Flour: 1 1/4 cups

Butter: 3/4 cup

Now let's compare the amounts with the required ingredients for a batch of cookies:

Required amount per batch:

Flour: 3/4 cup

Butter: 1/3 cup

First, let's see how many batches of cookies Alice can make:

Flour: Alice has 2 cups, and each batch requires 3/4 cup. So she can make 2 cups / (3/4 cup) = 8/3 = 2 and 2/3 batches of cookies.

Butter: Alice has 1/4 cup, and each batch requires 1/3 cup. Since she doesn't have enough butter for a full batch, she can't make any batches of cookies with the butter she brought.

Next, let's see how many batches of cookies Maria can make:

Flour: Maria has 1 1/4 cups, and each batch requires 3/4 cup. So she canmake (5/4 cups) / (3/4 cup) = 5/3 = 1 and 2/3 batches of cookies.

Butter: Maria has 3/4 cup, and each batch requires 1/3 cup. So she can make (3/4 cup) / (1/3 cup) = 9/4 = 2 and 1/4 batches of cookies.

Now, to find the maximum number of whole batches they can make together, we take the minimum of the number of batches each student can make:

Alice: 2 and 2/3 batches

Maria: 1 and 2/3 batches

Raul: Not mentioned, so we assume he brought the required ingredients.

The minimum value is 1 and 2/3 batches, which means they can make 1 whole batch of a dozen cookies together.
