Answer:

(-1,-4)

Step-by-step explanation:

Because it is a rotation that turns both the x and y values the two swap places. The x value become negative because before it was in quadrant 4 where there was still a positive chance but rotating the point clockwise puts it into the third quadrant where there are only negatives.

Quadratic formula where:
$ax ^{2} + bx + c$
$\frac{ - b + { \sqrt{b^{2} - 4ac } }}{2a}$
$\frac{ - b - \sqrt{b { }^{2} - 4ac } }{2a}$
do both do get the roots of the equation

Find the arc length of a 30 degree sector of a circle with a radius of 10 cm

Elena-2011 [213]

Arc length = Ф/360 * 2πr
= 30/360 * 2*3.14*10
= 1/12 * 62.8
= 5.23

In short, Your Answer would be 5.23 cm

Hope this helps!

If a rectangle has perimeter of 70 a length of x and a width of x-9, find the value of the length of a rectangle

iren2701 [21]

Answer:

length = 22

width = 13

Step-by-step explanation:

Perimeter of a rectangle is given by the formula

P =2(l+w)

we know the length is x

width is x-9

P =70

Substituting this into the equation

70 = 2(x+x-9)

Combining like terms

70=2(2x-9)

Distributing the 2

70 = 4x-18

Adding 18 to each side

70+18 = 4x-18+18

88 = 4x

Divide by 4

88/4 = 4x/4

22= x

we know the length is x

length = 22

width is x-9

width = 22-9= 13
