Answer: G(x) = cos(x) - 1

Step-by-step explanation:

We know that y = cos(x)

remember that cos(0) = 1.

Now, by looking at the image we can see that G(x) seems to be a vertical shift.

Remember that for a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

If N is positive, the shift is up

if N is negative, the shift is down.

In this case we can see that when x = 0, G(0) = 0.

And remember that cos(0) = 1, then G(x) is one unit below the graph of y = cos(x).

Then we can see that G(x) is a vertical shift of one unit downwards.

Then:

G(x) = cos(x) - 1

What is the value of the sin3x/6x; as x approaches to zero
nikklg [1K]

Step-by-step explanation:

When x = 0,

sin3x / 6x = 0 / 0, which is an indeterminate form.

Hence we use L'Hospital's rule:

d/dx (sin3x) = 3cos3x

d/dx (6x) = 6

Now we have 3cos3x / 6 or 0.5cos3x.

When x = 0, 0.5cos3x = 0.5(1) = 0.5.

Hence the limit is 0.5.

Which of the following tables shows the correct steps to transform x2 + 10x + 24 = 0 into the form (x − p)2 = q? [p and q are in
IRINA_888 [86]
1.
x² +10x +24 = 0
x² +10x =-24
2.
x² +2*5*x +5² =-24+5²
3.
x²+2*5*x+25 = -24+25
4.
(x+5)² = 1
p=-5, q=1

The top and bottom ends of a windshield wiper blade are R = 24 in. and r = 14 in., respectively, from the pivot point. While in
Orlov [11]

Answer:

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