Your answer is False

The statement that describes the slope in this equation is that the score of each question is 5

From the question, we have the following parameters that can be used in our computation:

Equation: s = 100 - 5m

Also from the question, we have:

s = The total score

m = the number of questions a student missed

Recall that

s = 100 - 5m

A linear equation is represented as

y = mx + c

Where m = slope

By comparing the equations, we have

m = -5

Given that a circle has a center (0,4) and the radius 5. 5. So the standard equation of the given circle is x2+(y−4)2=25.

Step-by-step explanation:

3xy has two terms, 3 and xy. The term 3 is a constant and the term xy is a product of two variables.

3xy is a multiplication of three individual components. It consists of three distinct parts, namely 3, x, and y. Each of these components is considered a distinct term, so 3xy has three terms in total. The 3 represents a numerical value, while the x and y are variables that can be assigned any numerical value. When multiplied together, the three terms form a single expression, 3xy, which can then be evaluated for a resulting value.

The evaluation of the composite figure comprising of a square and an equilateral triangle is as follows;

9 (a) ∠ABD = 90°

(b) ∠BCD = 60°

(c) ∠ADC = 105°

A composite figure is a figure comprising of two or more regular geometric figures.

9. The shape of the quadrilateral ABDE = A square

The kind of triangle specified for the triangle ΔBCD = Equilateral triangle

The sides of the square ABDE are congruent by the definition of a square

Therefore; AB = BD = DE = AE by the definition of congruency

(a) Angle ∠ABD is a corner of the square ABDE, therefore;

The size of angle ∠ABD = 90° (properties of the interior angle of a square)

(b) The size of angle ∠BCD = 60° (Interior angle of an equilateral triangle)

(c) The size of angle ∠ADC is found as follows;

Triangles ΔAED and triangle ΔABD formed by the diagonal AD are congruent by Side-Side-Side, SSS congruency postulate

∠DAB ≅ ∠ADB (base angles of isosceles triangle ΔABD)

∠DAB = ∠ADB (Definition of isosceles triangles)

∠ABD + ∠DAB + ∠ADB = 180° (Angle sum properties of a triangle)

90° + 2 × ∠ADB = 180° (substitution property)

∠ADB = (180° - 90°) ÷ 2 = 45°

∠BDC = 60° (Interior angle of an equilateral triangle)

∠ADC = ∠ADB + ∠BDC (Angle addition postulate)

Therefore, ∠ADC = 45° + 60° = 105°

To find the area of the base of the rectangular prism, we need to find the expression for the area of a rectangle with dimensions equal to the dimensions of the base of the prism.

The volume of a rectangular prism is given by the formula:

Volume = length * width * height

Substituting the given expressions for the volume and the height into this formula, we get:

6x3 + 19x2 + 2x - 3 = (length * width) * (x + 3)

Expanding the right-hand side of the equation, we get:

6x3 + 19x2 + 2x - 3 = length * width * x + length * width * 3

Matching the terms on the left-hand side of the equation with the corresponding terms on the right-hand side, we can see that the expression for the area of the base of the rectangular prism is:

length * width = 6x3 + 19x2 + 2x - 3 - length * width * 3

Simplifying this expression, we get:

length * width = -3x3 - 17x2 - 2x + 3

Therefore, the area of the base of the rectangular prism is given by the expression -3x3 - 17x2 - 2x + 3.

The height of the tree is 61.92 feet.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate a triangle's side length and angle.

Given that,

Distance of Tamara from tree = 30 feet.

Angle of elevation = 62°.

And the height of Tamara from the ground = 5.5 feet.

To find the height of the tree,

Use trigonometric formula,

tan θ = height / distance

tan 62 = x / 30

1.88 = x / 30

x = 56.42 feet

The total height of tree = x + 5.5 = 56.42 + 5.5 = 61.92 feet

The smallest number that is divisible by 3 is 3 itself. Every integer that is divisible by 3 is called a multiple of 3.

For example, some of the multiples of 3 are 6, 9, 12, 15, 18, 21, etc. All of these numbers can be obtained by multiplying 3 by an integer.

If a number evenly divides (leaves no residue) into another number, it can be divided. For instance, 34 may be divided by 2 equally, making it a divisible number. However, because doing so would result in a leftover, 34 cannot be divided by 3.

According to the law of three's divisibility, a number is completely divisible by three if the sum of its digits is also divisible by three. Take 308 as an example. To determine whether or not 308 is divisible by 3, add the digits together and find the sum (3+0+8=11).

2375 is the amount of his investment and 625 is his total profit

The discount on the shares is 5%, so the price of each share is 100 - (5/100)100 = 95.

The total price Yoezer paid for the shares is 2595 = 2375.

To calculate Yoezer's total profit, we need to find the total dividend he received and the price he sold the shares for.

The dividend rate is 15%, so Yoezer received a dividend of (15/100)100 = 15 on each share.

The total dividend he received is 1525 = 375.

The price Yoezer sold the shares for was increased by a premium of 5%, so the selling price was 100 + (5/100)100 = 105.

The total selling price for the shares is 10525 = 2625.

Yoezer's total profit is the selling price minus the price he paid for the shares plus the dividends he received. This is 2625 - 2375 + 375 = 625.
