1 answer:

7 0

<span>Given: 4y =2x-10, and y=6 Substituting for y in the equation gives 4(6) = 2x-10 or 24 = 2x-10 Adding 10 to both sides of the equation 24+10 = 2x - 10+10 34 = 2x Dividing both sides by 2 34/2 = 2x/2 Answer 17 = x</span>

Find the perimeter of the shaded region. Round your answer to the nearest hundredth.

nataly862011 [7]

Answer:

59.16 units

Step-by-step explanation:

Given that,

The length of rectangle, L = 13

The breadth of the rectangle, B = 6

The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)

$P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16$

So, the perimeter of the shaded region is 59.16 units.

If cos theta = -3/5 in quadrant 2, what is sin theta?

mote1985 [20]

Answer:

hello : sin(θ) = 4/25

Step-by-step explanation:

you know : cos²(θ) + sin²(θ) =1 and : cos(θ) = - 3/5

(-3/5)² + sin²(θ) =1

9/25 + sin²(θ) =1

sin²(θ) =1 -9/25

sin²(θ) = 16/25

sin(θ) = 4/25 or sin(θ) = - 4/25

in quadrant 2 : sin(θ) > 0

so : sin(θ) = 4/25

Solve for x and simplify answer as much as possible

pantera1 [17]

Answer:

$x=-1$

Step-by-step explanation:

$4=6+2x$

Flip the equation:

$2x+6=4$

Subtract 6 from both sides:

$3x+6-6=4-6$

$2x=-2$

Divide both sides by 2:

$2x/2=-2/2$

$x=-1$
