Orlov [11]

Answer:

Area swept by the blade = 448 $in^{2}$

Step-by-step explanation:

The arc the wiper wipes is for 135 degrees angle.

So, find area of sector with radius 24 inches. And the find area of arc with r=14 inches.

Then subtract the area of sector with 14 inches from area of sector with radius as 24 inches.

So, area of sector with r=24 in = $\frac{135}{360} *\pi *24^{2}$

Simplify it,

=216 $\pi$

Now, let's find area of sector with radius 14 inches

Area of sector with r=14 in = $\frac{135}{360} *\pi *14^{2}$

Simplify it

=73.5 $\pi$

So, area swept by the blade = 216 $\pi$ -73.5 $\pi$

Simplify it and use pi as 3.14.....

Area of swept =678.584 - 230.907

=447.6769

Round to nearest whole number

So, area swept by the blade = 448 $in^{2}$

Answer:

- $12n^{2}$ + 12

Step-by-step explanation:

h(n) = -4n + 4 (h o g) (n)

g(n) = $3n^{2}$ - 2

-4( $3n^{2}$ - 2) + 4

- $12n^{2}$ + 8 + 4

- $12n^{2}$ + 12

Which sequence represents an arithmetic sequence?

Sergio039 [100]

we know that

arithematic sequence will always have common difference

(a)

−5, −7, −10, −14, −19, …

we can see that

$d_1=-7+5=-2$

$d_2=-10+7=-3$

they are not equal

so, this is not arithematic sequence

(2)

1.5, −1.5, 1.5, −1.5, …

we can see that

$d_1=-1.5-1.5=-3$

$d_2=1.5+1.5=3$

they are not equal

so, this is not arithematic sequence

(3)

4.1, 5.1, 6.2, 7.2, …

we can see that

$d_1=5.1-4.1=1$

$d_2=6.2+5.1=1.1$

they are not equal

so, this is not arithematic sequence

(4)

−1.5, −1, −0.5, 0, …

we can see that

$d_1=-1+1.5=0.5$

$d_2=-0.5+1=0.5$

they are equal

so, this is arithematic sequence
