What is the equation of the blue line?

Answers

Answer:

y = (1/2)x + 2

Step-by-step explanation:

it is a straight line so it will be in the form of y = mx + c

m = gradient, c = y intercept

Reading from graph it cuts the y-axis at 2,

so c = 2

to find gradient we can pick any 2 points on the line,

e.g (0,2) and (10,7)

gradient = (y1 - y2) / (x1 - x2) = (7 - 2) / (10 - 0)

= 1/2

so the equation is y = (1/2)x + 2

Using slope intercept formula, the equation of the blue line

y = (1/2)x + 2.

What is slope intercept?

The slope intercept form is one of the form to represent" equation of the straight iine".

According to the question,

The graph intercept the y-axis at 2.

Slope intercept formula, y = mx + c where m = slope of the line, c = y- intercept of the line,  x, y as variable.

From given, y-intercept, c = 2.

To find slope of the line take any two points on the line (0,2) and (10,7).

Formula to find slope of the line m = (y₁ -y₂)/(x₁ - x₂).

m = (2-7)/(0-10)=  [tex]\frac{1}{2}[/tex]

Hence, the equation of the blue line  y = (1/2)x + 2.

HELP please my friend needs help with his MATH homework, see picture for problem TY :)

Answers

Answer: 207.34512

Plug in values into your formula
SA = 2•pi•r^2 + 2•pi•r•h

SA = 2•pi•3^2 +2•pi•3•8

Height (h) = 8in.
Radius (r) = 3 (diameter divided by 2)
Diameter = 6
The formula for surface area is
SA = 2πr^2 + 2πrh
Where SA means surface area, r stands for radius, and h stands for height.

First find the radius. The radius of a circle is the distance from the outside of the circle to its center. It is half the diameter. To find the radius, divide the diameter by two.
r = 6/2
r = 3 inches

Now plug in the values for radius and height into your formula. Use pi = 3.14

SA = 2(3.14)r^2 + 2(3.14)rh
SA = 2(3.14)(3)^2 + 2(3.14)(3)(8)
SA = 6.28(9) + 6.28(24)
SA = 56.52 + 150.72
SA = 207.24 inches

1 A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10
centimeters. Which measurement is closest to the total surface area of the can in
square centimeters?

Answers

Answer:

radius r = 3 cm

height h = 10 cm

volume V = 282.743339 cm^3

lateral surface area L = 188.495559 cm^2

top surface area T = 28.2743339 cm^2

base surface area B = 28.2743339 cm^2

total surface area A = 245.044227 cm^2

In Terms of Pi π

volume V = 90 π cm3

lateral surface area L = 60 π cm^2

top surface area T = 9 π cm^2

base surface area B = 9 π cm^2

total surface area A = 78 π cm^2

Step-by-step explanation:

Cylinder Formulas in terms of r and h:

Calculate volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**:

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Agenda: r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root

The value of Surface Area of the cylinder is 245.04 cm².

What is Surface Area of a shape ?

Surface area is the amount of space covering the outside of a three-dimensional shape.

It is given that the cylinder has

radius r = 3 cm

height h = 10 cm

volume V of the cylinder = πr²h = 282.74 cm³

the lateral surface area of a cylinder

L = 2πrh

lateral surface area L = 188.495559 cm²

the top and bottom surface area of a cylinder (2 circles):

T = B = πr²

top surface area T = 28.2743339 cm²

base surface area B = 28.2743339 cm²

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

total surface area A = 245.044227 cm²

total surface area A = 78 π cm²

Therefore the value of Surface Area of the cylinder is 245.04 cm².

Step-by-step explanation:

The slope of the road will be equal to 11 / 141.

What is the slope?

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise to the run.

Given that a local road rises 33 feet for every 423 feet of pavement.

The slope of the road will be calculated as,

Slope = Rise / Run

Slope = 33 / 423

Slope = 11 / 141

Therefore, the slope of the road will be equal to 11 / 141.

The graph of a quadratic equation in two variables whose axis of symmetry is parallel to the y axis is a parabola.
Select one:

The correct option is;

False

Step-by-step explanation:

The equation of the graphs of conic sections (all of which can have axis of symmetry that can be oriented parallel to the y-axis) includes;

Circle; (x - h)² + (y - k)² = r²

Parabola; y = a·(x - h)² + k
