Determine whether the representation is proportional. y = -9x

Answers

Answer 1

Answer:

Yes, they are

Step-by-step explanation:

y = -9x

Here y∝ x

Where -9 is constant of proportionality

If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

Answer:

B, the second answer.

Step-by-step explanation:

If you count all of the boxes you will see there are 16 so that will be your denominator and then count the shaded blocks and that is you numerator.

So it would look like 5/16 and then convert it into a percent to be 31.25%

Step-by-step explanation:

There is a common difference d in the values, that is

9 - 5 = 13 - 9 = 17 - 13 = 21- 17 = 4

To obtain a term in the sequence add 4 to the previous term, thus

t₉ = t₈ + 4 → C

(b)

Given the n th term formula 3n - 8

To find any term, substitute the term position n into the formula

(i) first term (n = 1), then

3(1) - 8 = 3 - 8 = - 5

(ii) tenth term (n = 10, then

3(10) - 8 = 30 - 8 = 22

(iii) 100 th term ( n = 100), then

3(100) - 8 = 300 - 8 = 292

A model of Steven’s house is shown in the diagram. He is replacing the roof, which consists of two rectangular surfaces. The diagram shows one side of the roof, with the other side hidden from view. What is the total area of the roof to the nearest square foot?

Answers

Answer:

Option B

Step-by-step explanation:

From the picture attached,

Area of the one side of the roof = Area of the rectangle

                                                     = Length × Width

                                                     = AE × AC

To get the length of side AC, construct a perpendicular AD on side BC which divides BC in two equal parts.

BD = DC = 13 ft

By applying cosine rule in ΔADC,

cos(45)° = [tex]\frac{\text{DC}}{\text{AC}}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{13}{\text{AC}}[/tex]

AC = 13√2

AC = 18.38 ft

Therefore, area of one side of the roof = 38 × 18.38

                                                                 = 698.62 square feet

Area of both the sides of the roof = 698.62 × 2

                                                        = 1397.24 feet²

                                                        ≈ 1397 feet²

Option B will be the answer.

The total area of the roof to the nearest square foot is 1,397 square feet

Area of composite shapes.

In order to get the area of the roof, we will need the slant height of the triangle.

Using the pythagoras theorem;

[tex]cos45 = \frac{26/2}{l} \\cos 45 = \frac{13}{l} \\0.7071 = \frac{13}{l} \\l = \frac{13}{0.7071} \\l=18.39 feet[/tex]

Get the area of the roof

Area of the roof = 2(lw)

l is the length of the rectangle = 38ftw is the width  = 18.39 feet

Area of the roof = 2(38 * 18.39)

Area of the roof = 1,397.64

Area of the roof ≈ 1,397 square feet

Hence the total area of the roof to the nearest square foot is 1,397 square feet

The lakeside marina charges a $35 rental fee for a boat in addition to charging $15 per hour. Part D:what information does the initial value represent? A.The cost of renting a boat for one hour B.The cost of rental fee only C.The cost of rental fee plus the boat for one hour D.The cost of renting the boat more than one hour

Answers

Answer: B.The cost of rental fee only

Step-by-step explanation:

The $35 is the cost of the rental fee only. The person would then have to pay a further $15 for every hour they use the boat.

Essentially, the $35 is the fixed cost associated with the rental and the $15 is the variable cost to do so. If this were in a linear equation format it would take the form: y = 15x + 35.

What is the equation of a line that has a slope of 0 and goes through the point (4, 10)?

Answers

Answer:

y =10

Step-by-step explanation:

The equation of a line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given

m = 0 and (x0, y0) = (4, 10)

On substituting;

y - 10 = 0(x-4)

y - 10 = 0

y = 0+10

y = 10

Hence the required equation of the line is y =10
