To find the reciprocal of a number, just flip the numerator and the denominator around.

A. The reciprocal of 2/3 is 3/2.

C. Firstly, convert the mixed fraction into an improper fraction. Multiply the whole number by the denominator and add the numerator to that product. After that, put the quantity on the numerator. In this case, 6 x 6 = 36 and 36 + 1 = 37, so our improper fraction is 37/6. Next, just flip the numerator and denominator around, and your reciprocal is 6/37.

Thru (4,0) parallel to y=1/2x+5

Ne4ueva [31]

Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)

x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b

the equaiton is
y=1/2x-2
or
x-2y=4

ASAP<br>Find all solutions to the equation.<br><br><br>7 sin^2 x - 14 sin x + 2 = -5

matrenka [14]

Answer:

{-π/2, π/2}

Step-by-step explanation:

Rewrite this as:

7sin^2 x - 14sin x + 7 = 0. Reduce this result by dividing all terms by 7:

sin^2 x - 2sin x + 1

Temporarily replace "sin x" with y:

y^2 - 2y + 1 = 0

Solve this through factoring: (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1

Recalling that y = sin x, we write

sin x = ±1, whose solutions are sin x = 1 and sin x = -1

The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2

and so the solution set is {-π/2, π/2}

find the area of the shape below

Norma-Jean [14]

Answer:

235 cm²

Step-by-step explanation:

Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.

Length of big rectangle=20 cm

Width of big rectangle=9 cm

20x9=180 cm²

Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.

Length of small rectangle=11 cm

Width of small rectangle=5 cm

I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.

11x5=55 cm²

Add the areas of the two rectangles.

55+180=235 cm²
