Answer:

y = 3x/2

Step-by-step explanation:

Let's solve for y first.

3y = -2x+6

y = -2x/3 + 2

We know that the slope is perpendicular to -2/3, meaning that we have to find the negative reciprocal of -2/3, which is 3/2.

y = 3x/2 + C.

We know the point (2, 3) and we plug that into our equation above.

3 = 3/2(2) + C.

3 = 3 + C

0 = C

C = 0.

We now plug in C for the equation, which gives us y = 3x/2.

Please answer ASAP! If 0 is an angle in quadrant II, what is the value of sin(0)

natka813 [3]

Answer:

Option A

Step-by-step explanation:

It's given that cosθ = $-\frac{2\sqrt{5} }{5}$

Since, cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$ = $-\frac{2\sqrt{5} }{5}$

= $\frac{2}{\sqrt{5}}$

By applying Pythagoras theorem in the right triangle,

(Hypotenuse)² = (Opposite side)² + (Adjacent side)²

(√5)² = (Opposite side)² + (2)²

5 = (Opposite side)² + 4

Opposite side = √(5 - 4)

= 1

Since, sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{1}{\sqrt{5}}$

Since, sine is positive in IInd quadrant,

sinθ = $\frac{1}{\sqrt{5}}$

Therefore, option A will be the answer.

I need help with my math

Nat2105 [25]

Answer:

Part A. C=9

Part B. (w+3)² =139

Part C. w = 8.8 inch

Step-by-step explanation:

Given from the question length of the the picture = (2w+12) inches

Width of the picture = w inches

Area of the picture = 260 inch²

Part A. Area of the picture with the given dimensions= w×(2w+12)

Or w(2w+12) = 260

2w²+12w = 260

2(w²+6w) = 2×(130)

w²+6w = 130

Or w²+6w +9 = 130+9 ⇒ which is in the form of w²+6w+c = 130+c

Therefore for c = 9 we will get a perfect square trinomial.

Part B. As we have seen the equation in part A.

As required equation will be (w+3)²=139

Part C. Since (w+3)² = 139

Then by taking under root on both the sides of the equation

(w+3) =√139 = 11.8

(w+3)-3=11.8-3

w = 8.8 inch
