Answer:

neither a or b

Step-by-step explanation:

a function has to have each X have a Y

a domain is paired with exactly one range value.

it has to pass the vertical line test

independent variable is X

dependant variable is Y

student name = x

colors/teachers is Y

so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function

The distance from point A to B is 2723.8 feet.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let h represent the height of the light house, hence:

tan(9) = h/1347

h = 213.3 feet

Let d represent the distance from point B to the lighthouse base, hence:

tan(3) = 213.3/d

d = 4070.8 feet

Distance from point A to B = 4070.8 feet - 1347= 2723.8 feet.

Answer:

8 quarts

Step-by-step explanation:

There are 4 quarts in a gallon. If 1/3 of a gallon cover 1/6 of a wall, then an entire gallon will cover 1/2 of the wall. This means that 2 gallons will completely cover the wall. 2 gallons equals 8 quarts.

Answer:

8 quarts

Step-by-step explanation:

1/3 of a gallon = 1/6 of the wall

x of gallon = 1 of the wall

so x = 1/3 * 6 = 2 gallons

and 1 gallon = 4 quarts

then 2 gallon = 4*2 = 8 quarts

Answer:

1: x=-3

2: x=1 is the answer

p = x² coefficient * x⁰ coefficient

= 6 * -3 = -18

R = x coefficient = 7

now you have to find 2 numbers that multiply to give -18 and add to give 7

the numbers are 9 and -2

so

S = 9

P = -18

q = -2

r = 7

Answer:

so you graph at (0,2), and go up one, over two for every other point you graph.

Step-by-step explanation:

rise over run.

basically, the m is the slope, and b is the y intercept (where it intersects the y axis).

so when looking at how to graph the line based on 1/2 or any other number, I use rise/run, which is basically telling us tha we need to go up one and over 2 (1/2)

if that makes any sense, let me know if you have any further questions. you got this, youre doing your best!!

slope is the start of your endless pain.

Probabilities are used to determine the chances of an event

The value of P(Jack and then Queen) is 4/663

The given parameters are:

n = 52

Jack = 4

Queen = 4

The probability P(Jack and then Queen) is calculated as:

P(Jack and then Queen) = P(Jack) * P(Queen)

So, we have:

[tex]P = \frac{4}{52} * \frac{4}{51}[/tex]

Simplify

[tex]P = \frac{1}{13} * \frac{4}{51}[/tex]

Evaluate the product

[tex]P = \frac{4}{663}[/tex]

Hence, the value of P(Jack and then Queen) is 4/663

Step-by-step explanation:

Because an acre is 10 times the size of a football pitch and is often used area as a unit of measurement for broad regions, answer option (D) is a plausible estimate.

The size of a surface area can be expressed as an area. The surface area is the area of an open surface or the boundary of a three-dimensional object, whereas the area of a planar region or planar region refers to the area of a shape or flat layer. The area of an object is the entire amount of space occupied by a planar (2-D) surface or shape. Make a square with a pencil on a piece of paper. A two-dimensional character. On paper, the area of a shape is the amount of space it takes up. Assume the square is made up of smaller unit squares.

(D) 4 104 sq ft is the right answer.

Considering that an acre of land has an area of exactly 43,560 square feet, answer selections (A) and (C) are both too tiny, as they are both less than 1% of the size of an acre. Answer option (B) is 100 times the size of an acre and hence far too huge.

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 3.875/100

r = 0.03875 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.03875/12)(12)(7.5)

A = 10,000.00(1 + 0.003229167)(90)

A = $13,366.37

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 3.875% per year compounded 12 times per year over 7.5 years is $13,366.37.

Answer:

Step-by-step explanation:

it’s 9.55 au

Saturn is 9.57 au  far from the sun

Kepler's third law, also called the law of periods, states that the square of the orbital period is proportional to the cube of its mean distance R.

Let time period of earth = T (e)

Time period of Saturn will be = T(s) = 29.5 T(e)

(since , it is given that Saturn orbits every 29.5 years )

distance of earth from sun = r(e) = 1.5 * [tex]10^{11}[/tex] m

distance of Saturn from the sun = r(s) = ?

using Kepler's third law

[tex]T^{2}[/tex] is directly proportional to [tex]r^{3}[/tex]

[tex]T(s)^{2}[/tex]/[tex]T(e)^{2}[/tex] = [tex]r(s)^{3}[/tex] / [tex]r(e)^{3}[/tex]

Answer:

$94.325

Step-by-step explanation:

Given interest (I) varies directly as rate of interest (R) then the equation relating them is

I = kR ← k is the constant of variation

To find k use the condition I = 49 when R = 4 , then

49 = 4k ( divide both sides by 4 )

12.25 = k

I = 12.25R ← equation of variation

When R = 7.7 , then

I = 12.25 × 7.7 = $94.325
