Answer:

Part 1) x=\frac{10\sqrt{3}}{3}\ units

Part 2) y=5\ units

Step-by-step explanation:

step 1

Find the value of x

In the right triangle of the figure

sin(30^o)=\frac{(5\sqrt{3}/3)}{x} ---> opposite side angle of 30 degrees divided by the hypotenuse

Remember that

sin(30^o)=\frac{1}{2}

substitute

\frac{1}{2}=\frac{(5\sqrt{3}/3)}{x}

solve for x

x=\frac{5\sqrt{3}}{3}(2)

x=\frac{10\sqrt{3}}{3}\ units

step 2

Find the value of y

In the right triangle of the figure

cos(30^o)=\frac{y}{x} ---> adjacent side angle of 30 degrees divided by the hypotenuse

we have

x=\frac{10\sqrt{3}}{3}\ units

cos(30^o)=\frac{\sqrt{3}}{2}

substitute

\frac{\sqrt{3}}{2}=\frac{y}{\frac{10\sqrt{3}}{3}}    

y=(\frac{\sqrt{3}}{2})(\frac{10\sqrt{3}}{3})

y=5\ units

Write the equation in standard form for the circle with center (0, -1) and radius 10.
BARSIC [14]

Answer:

x^2 + (y+1)^2 = 10^2

Step-by-step explanation:

Centre (p,q) = (0, -1)

radius, r = 10

General Equation of a circle

(x-p)^2 + (y-q)^2 = r^2

(x-0)^2 + (y- -1)^2 = 10^2

x^2 + (y+1)^2 = 10^2

Which linear equations has a slope of -3 and a y intercept of 4
Pavlova-9 [17]
This would be represented by the function Y = -3x + 4 C:

just remember that your slope is your X value, and on a graph it is your rise over run. since -3 is your slope, you go down -3(your rise, you go down since it is negative) and over one. its a whole number instead of a fraction because -3/1 is simplified to -3. Your Y intercept is the added number in the end of the equation. Basically they are your values in the linear equation, which is Y = mx + b
