Step-by-step explanation:

Answer:

For an expression to be a polynomial term, any variables in the expression must have whole-number powers (or else the "understood" power of 1, as in x1, which is normally written as x). A plain number can also be a polynomial term.

[tex] i = \frac{v}{r} [/tex]

2)no ohms

3)

[tex]r = \frac{v}{i} [/tex]

4)

[tex] \frac{550}{1.5} = r \\ \\ r = 366.66 [/tex]

A(1). The Equation to isolate I will be I = V / R.

B(2).If V=220 volts and R= 2 ohms, what is the value for I will be 110 amperes

C(3). The equation to isolate R will be R = V / I.

D(4).If V=550 and I=1.5 amperes, what is the value of R will be 366.66 Ohms.

Ohms's law of electricity states that the current passing through the closed circuit is directly proportional to the voltage developed across the circuit.

Where R is the constant and called the resistance. The resistance is actually the restriction offered by the material in the flow of the charge or current.

The mathematical form of Ohm's law is given as:-

V=IR,

where V is voltage, I is current, and R represents the resistance.

A). The Equation to isolate I will be,

I = V / R.

B). If V=220 volts and R= 2 ohms, what is the value I will be

I = V / R

I = 220 / 2 =110 Volts.

C). The equation to isolate R will be,

R = V / I.

D). If V=550 and I=1.5 amperes, what is the value of R will be,

R = V / I

R = 550 / 1.5 = 366.66 Ohms.

Answer:

  25.12 cm²

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

where r is the radius. Here, the diameter is given as 8 cm, so the radius will be half that, or 4 cm. The area is then ...

  A = 3.14(4 cm)² = 50.24 cm²

The green shaded part is 1/2 a circle, so is half this area:

Answer:  35 miles

Step-by-step explanation:

If 4 miles is 20 minutes that mean 1 mile is 5 minutes so just add 4+3 which is 7 then multiply that by 5 which is 35 so it takes him 35 minutes to go to his friends house

Given:

To find:

a.

Distance from Josiah's house to school = 4 miles

Time taken by Josiah on a skateboard to cover 4 miles = 20 min

The speed of Josiah's skateboard = S

[tex]Speed=\frac{Distance}{Time}\\\\S=\frac{4 miles}{20 min}\\\\S=0.2 miles/min[/tex]

The Josiah's speed, the constant of proportionality is 0.2 miles per minute.

b.

Distance From school to Sebastian's house = 3 miles

Time taken by Josiah on a skateboard to travel to Sebastian's house from school = t

The Josiah's speed, the constant of proportionality = 0.2 miles/min

[tex]0.2 miles/min=\frac{3 miles}{t}\\\\t=\frac{3 miles}{0.2 miles/min}=15 min[/tex]

The time taken by Josiah on his skateboard to Sebastian's house is 15 minutes.

A line is found to be a one dimensional figure, which has length but no width. The another name for the line n is line. The two points which lie on the same line are called collinear points. The correct option is D.

A straight set of points which can extend in opposite directions can be defined as the line. It has no ends in both directions, no thickness and it is one dimensional. It is determined by two points in a two dimensional plane.

In geometry, there are different types of lines like horizontal and vertical lines, parallel and perpendicular lines. The lines play an important role in the construction of different types of polygons.

A square is made by four lines of the same lengths, whereas a triangle is made by joining three lines end to end.

Answer:

48 designs

Step-by-step explanation:

Total pieces of clothes = 3

Area covered by each design on a piece of cloth = 1/16

How many types of designs can Alice embroider on the three pieces of cloth

Number of designs Alice can embroider on 3 pieces of cloth = Total pieces of cloth / area covered by each embroidery

= 3 ÷ 1/16

= 3 × 16/1

= 48

Therefore, Alice can embroidery 48 types of designs on the 3 pieces of clothes

I'll be using the following variables and values

I will also be using the two kinematics equations

where Vi and Vf are the initial and final velocities respectively, 'a' is the acceleration, t is time, and x is displacement.

----------------------------------------------------------------------------------------------

To start, let's focus on just the accelerating portion of the journey.

The elevator starts at rest, so VS1 = 0. It reaches some current unknown final velocity, but we can calculate that as such

Vf = Vi + at  

VF1 = VS1 + a1*t

VF1 = 0 + 0.6*t

VF1 = 0.6t

The elevator reaches a top speed of 0.6t meters per second after traveling and accelerating t seconds.

----------------------------------------------------------------------------------------------

Let's see how much the elevator is displaced after those t seconds (again only focus on the journey where the elevator is speeding up for now)

x = Vi*t + 0.5*at^2

d1 = VS1*t + 0.5*a1*t^2

d1 = 0*t + 0.5*0.6*t^2

d1 = 0.3t^2

The elevator travels 0.3t^2 meters when it is speeding up. We'll use this later.

----------------------------------------------------------------------------------------------

Now onto the portion where the elevator is slowing down.  

The starting speed for this portion is VS2 = VF1 = 0.6t because the transition from the last bit of the accelerating portion to the decelerating portion has no gaps. Let's assume it's a smooth transition without any sudden bumps to make the ride uncomfortable.  

Let's find the displacement for this portion.

x = Vi*t + 0.5*at^2

d2 = VS2*(10-t) + 0.5*a2*(10-t)^2 .... note the 10-t terms

d2 = 0.6t*(10-t) + 0.5*(-0.8)(100-20t+t^2)

d2 = 6t-0.6t^2 - 40+8t-0.4t^2

d2 = -t^2 + 14t - 40

This is the distance it travels from its top speed, decelerating all the way down to rest.  

----------------------------------------------------------------------------------------------

Add the two distances

d = total distance

d = d1+d2

d = ( d1 ) + ( d2 )

d = ( 0.3t^2 ) + ( -t^2 + 14t - 40 )

d = 0.3t^2 - t^2 + 14t - 40

d = -0.7t^2 + 14t - 40

If we knew the value of t (as defined at the very top of this solution), then we could find the total distance traveled.

----------------------------------------------------------------------------------------------

Let's find that value of t.

Recall the following three items

So,

Vf = Vi + at

VF2 = VS2 + a2*(10-t) ..... note the 10-t portion

0 = 0.6t + (-0.8)(10-t)

0 = 0.6t - 8 + 0.8t

0 = 1.4t - 8

8 = 1.4t

1.4t = 8

t = 8/1.4

t = 5.714 approximately

It takes about 5.714 seconds for the elevator to go from rest to its top speed, before the elevator starts the deceleration process.

----------------------------------------------------------------------------------------------

We can now find the value of d

d = -0.7t^2 + 14t - 40

d = -0.7(5.714)^2 + 14(5.714) - 40

d = 17.1411428

d = 17.1 is the approximate total distance traveled (in meters)

Answer:

(3x + -4) + 5x

Step-by-step explanation:

The algebraic expression is 8x - 4.

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operation.

Now it is given that, x represents the unknown number.

And the given statement is,

The sum of 3 times a number and -4 ​, added to 5 times the number

So numerically it can be written as,

∵ 3 times a number = 3x

∴ sum of 3 times a number and -4 ​ = 3x -4

and,

5 times the number = 5x

So, the algebraic expression we get,

3x - 4 + 5x

Simplifying it we get,

8x - 4

Thus, the algebraic expression is 8x - 4.
