What is the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compare

Elena-2011 [213]

Answer:

38.9 square inches.

Step-by-step explanation:

We are asked to find the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compared to a pair of 5 inch wipers operating together each having a central angle of 114 degrees.

We will use area of sector formula to solve our given problem as:

$\text{Area of sector}=\frac{\theta}{360}\times \pi r^2$ , where, r represents radius and theta represents central angle.

Let us find area of sector with central angle 140 degree and radius 3 inch.

$\text{Area of sector}=\frac{138}{360}\times \pi (3)^2$

$\text{Area of sector}=\frac{138}{360}\times 9\pi$

$\text{Area of sector}=10.83849$

Now, we will find area of sector with central angle 114 degree and radius 5 inch and multiply by 2 as:

$\text{Area of sector}=2(\frac{114}{360}\times \pi (5)^2)$

$\text{Area of sector}=2(\frac{114}{360}\times 25\pi)$

$\text{Area of sector}=\frac{114}{360}\times 50\pi$

$\text{Area of sector}=49.74188$

Let us find difference of area as shown below:

$\text{Difference of areas}=49.74188-10.83849$

$\text{Difference of areas}=38.90339$

$\text{Difference of areas}\approx 38.9$

Therefore, the difference in area covered is approximately 38.9 square inches.

A curve is described by the following parametric equations: <br> x = 4-t<br> y = t^2 -2

marta [7]

Answer:

Step-by-step explanation:

Given

$x=4-t$

and $y=t^2-2\quad \ldots(i)$

So, $t=4-x$

Substitute the value of $t$ in $(i)$

$y=(4-x)^2-2$

$y+2=(4-x)^2$

So it represent a parabola shown in the figure

What is275,608 rounded to the newest thounsand

kumpel [21]

Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...

1. The number 5 is located in the thousands place

2. Since the number 6 is located in the hundreds place, it's telling 5 to go up a number (turning 5 into a 6)

275,608 ⇒ 276,000

So the answer is 276,000

Solve each equation or inequality.<br> 2-3 x<11

SSSSS [86.1K]

After solving the equation, x < -3 is the value of inequality 2-3 x<11

⇒ 2-3x < 11

⇒ -3x < 11 - 2

⇒ -3x < 9

⇒ x < -9/3

⇒ x < -3

<h3>How to solve an equation?</h3>

To solve linear equations, utilize the steps that are provided below.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.
To separate the variable term on one side of the equation, use addition or subtraction.
To find the variable, use division or multiplication.
The common denominator can be multiplied by each side of the equation to eliminate fractions.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
