Answers

Answer: A quadratic equation (also called a parabola)

Step-by-step explanation:

A line can be written as:

f(x) = a*x + c

This is a polynomial with degree 1.

Now, of we have two lines:

f(x) = a*x + c

and:

g(x) = d*x + e

And we multiply them, we will get:

f(x)*g(x) = (a*x + c)*(d*x + e) = a*d*x^2 + a*e*x + c*d*x + c*e

We can rewrite this as:

                                           = (a*d)*x^2 + (a*e + c*d)*x + (c*e)

This is a polynomial of degree = 2, this is a quadratic equation, then if you multiply two lines together, you get a quadratic equation (or a parabola)

ax^2+ bx + c

The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Ashley just lit a new candle and then let it burn all the way down to nothing.

Let L represent the length of the candle remaining unburned, in inches, t hours after the candle was lit.

The slope is calculated as,

m = (0 - 7) / (7 - 0)

m = - 1 inch per hour

Then the linear equation is given as,

L = - t + 7

The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.

I need help to understand before my test today

Answers

Answer:

75 degrees

Step-by-step explanation:

All the angles within a triangle added together equals 180 degrees, so:

x + 25 + 2x - 5 + x = 180

add like terms

4x + 20 = 180

subtract 20 from both sides

4x = 160

divide by 4

x = 40

Now input 4 into the equation for C

2(40) - 5 = 80 - 5 = 75

for a coordinate proof concerning an isosceles triangle, which coordinates might be easiest to use?

Answers

Answer:

(0,0) , (a,b) , (2a,2b) is the answer

Step-by-step explanation:

for a triangle to be isosceles, then two sides must be equal

To picture this, if we have a point at the origin, with coordinate (0,0); we can have the coordinates of the other points being the same so as to make the distance from the origin the same

Then from here, we can get that the length of the two sides are equal

From what we have, option 4 can be correct

This is because , finding the distance between two points is;

D = √(x2-x1)^2 + (y2-y1)^2

From what we have

The distance between (0,0) and (a,b) will give same answer for the distance between (a,b) and (2a,2b)

Answers

Answer:

An object moving along the x-axis is said to exhibit simple harmonic motion if its position as a function of time varies as

x(t) = x0 + A cos(ωt + φ).

The object oscillates about the equilibrium position x0.  If we choose the origin of our coordinate system such that x0 = 0, then the displacement x from the equilibrium position as a function of time is given by

x(t) = A cos(ωt + φ).

A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction.  Simple harmonic motion is repetitive.  The period T is the time it takes the object to complete one oscillation and return to the starting position.  The angular frequency ω is given by ω = 2π/T.  The angular frequency is measured in radians per second.  The inverse of the period is the frequency f = 1/T.  The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time.  It is measured in units of Hertz, (1 Hz = 1/s).

The velocity of the object as a function of time is given by

v(t) = dx(t)/dt = -ω A sin(ωt + φ),

and the acceleration is given by

a(t) = dv(t)/dt = -ω2A cos(ωt + φ) = -ω2x.

Triangle RST is an equilateral triangle.

Step-by-step explanation:

All three sides of the triangle are of equal length, therefore, because an isosceles triangle is when 2 sides of the triangle are the same length, a scalene triangle being when all sides are of different lengths, and a right triangle having a right angle (a 90 degree angle), this only leaves equilateral, all three sides being the same length, like in the triangle shown.

The floor of a new planetarium is a circle with a 13-yard diameter.A stage will occupy a quarter circle section of the floor.The material for the stage will cost $31.47 per square yard. If no material is wasted when making the stage,how could you find how much the stage will cost? Use 3.14

Answers

Answer:

$1,043.74

Step-by-step explanation:

Area of the circular floor = πr²

Since the stage only occupies a quarter circle section of the floor, then;

Area of the stage = πr²/4

Given

diameter of the floor = 13yd

radius = 13/2 = 6.5yd

Find the area of the stage;

Area of the stage = π(6.5)²/4

Area of the stage = 3.14(42.25)/4

Area of the stage = 33.16625yd²

If the material for the stage will cost $31.47 per square yard, this means;

1yd² = $31.47

33.16625yd² = x

Cross multiply

x = 33.16625*31.47

x = 1,043.74

Hence the stage will cost $1,043.74
