Answer:

y = (1/4)x + 20

Step-by-step explanation:

The general equation of a line is

y = mx+ b , where m is the slope of the line and b is the y-intercept of the line ( where the line intersects the vertical y-axis)

From the graph we can see that the line intersects the y-axis at 20, so our y- intercept is b = 20

Now will find the slope of the line, and for that we need any two points from the line.

For example let's pick points ( x1= 0, y1 = 20) and ( x2 = 4, y2 = 21)

the slope m = (y2-y1)/(x2-x1) = (21-20)/ (4-0) = 1/4

slope of the line is m = 1/4

The equation of the graph shown in the graph is

y = (1/4)x + 20

The angle of the triangular plot at which the surveyor stands is 83°

A triangle is a shape with three sides and three angles. From the information given, the sides of the three angles are different, we can say the triangle is a scalene triangle since no sides are equal.

To determine the angle of the triangular plot at which the surveyor stands, we need to use the cosine formula.

Given that:

Let's assume that the angle at which the surveyor stands is ∠A, then:

[tex]\mathbf{a^2= b^2+c^2-2 bc \times Cos A}[/tex]

Making cos A the subject, we have:

[tex]\mathbf{cos \ A = \dfrac{ b^2+c^2-a^2}{2bc}}[/tex]

[tex]\mathbf{cos \ A = \dfrac{ 250^2+200^2-300^2}{2(250 \times 200)}}[/tex]

[tex]\mathbf{cos \ A = 0.125}[/tex]

A = cos⁻¹ (0.125) ≅ 83°

P(blue) ≈ 14.3%

Step-by-step explanation:

probability P is calculated as

P = ( favourable outcome ) ÷ ( total number of possible outcomes )

here favourable outcome is blue of which there are 3

number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21

P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]

to convert to a percentage multiply the fraction by 100%

P (blue) = [tex]\frac{1}{7}[/tex] × 100% = 100% ÷ 7 ≈ 14.3% ( to the nearest tenth )

Answer:

h = -1.356

Step-by-step explanation:

Remark

This is one of those questions where you could solve for h in the formula and then just put values in for all the other variables. Since you have posted this on Brainly, I'll just use the formula given and my last step will be one of division

Formula

S = 2 * pi * r^2  + 2 * pi * r * h   Put the givens into the formula

Givens

S = 175 in^2

pi = 3.14

r = 6

h = ?

Solution

175 = 2 * 3.14 * 6^2 + 2 * 3.14 * 6 * h         Combine

175 = 226.08 + 37.68*h                             Subtract  226.08 from both sides

175-226.08 = 37.68*h                                Combine

-51.08 = 37,68*h                                         Divide by 37.68

h = - 51.08/37.68

h = -1.356

The equation of line is y = 7x - 21 and the initial y value of the function is given by y = -21

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 3 , 0 )

Let the second point be Q = Q ( 8 , 35 )

Now , the slope of the line between the points is given by the formula

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 35 - 0 ) / ( 8 - 3 )

Slope m = 35/5

Slope m = 7

Now , the equation of line is given by the formula ,

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 0 = 7 ( x - 3 )

y = 7x - 21

Now , the initial value of y is calculated when x = 0

So , substituting the value of x = 0 in the equation , we get

y = 7 ( 0 ) - 21

y = -21

Therefore , the initial value of y = -21

Hence , the equation of line is y = 7x - 21

Answer:

  (d)  opens the same; wider

Step-by-step explanation:

Multiplying a function by a constant has the effect of vertically scaling the graph of the function by a factor equal to that constant.

__

Here, you're multiplying by 2/3, so each y-value is 2/3 of its previous distance from the x-axis. The effect on the graph of a parabola is to make it "flatter", hence wider in appearance. This does not change the direction in which it opens.

The equation is 6(2x-1), where X is more than 0. When a shipping company charges $6 to ship a package that weighs up to 1 pound.

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound.

lets make an assumption that the total weight of the shipment is x pound and cost for shipping is y.

the shipping company charges $6 for the first pound.

Up to now, the charge is y=6

After 1 pound, i.e for the remaining (x-1) pounds, they charge $2 per pound.

So, the total charge will be, y=6+2(x-1)

weight is always starting from zero as there is no negative weight.so X>0

so the equation is 6(2x-1), where X is more than 0

Answer:

(0, 75)

Step-by-step explanation:

The y-intercept is the y-coordinate of a function when x is equal to 0. In other words, it is the point at which the function crosses the y-axis.

For the equation y = 8x + 75, you plug in x = 0 to get:

y = 8(0) + 75 = 75, meaning that y = 75 when x = 0.

This gives you the y-intercept (0, 75).
