Answer:

Step-by-step explanation:

• The shape of the curve is a rose curve.

• The domain are real numbers

• And the range is approximately from -2 to 2

The maximum value of r on the graph is 2

• Yes the graph is continuous and it is bounded above and below

• The graph is symmetrical about the x axis and not about the y axis.

• No asymptotes

Given angle D= 60 degrees, determine the PERIMETER of triangle ABC.
vaieri [72.5K]

Answer:

15*(1+root(3))

Step-by-step explanation:

BD=5, BC=5*root(3), you can find it by using trigonometry.

  • AC^2+DC^2=AD^2

AC^2=300, AC=10*root(3)

  • AB^2+BC^2=AC^2

AB^2=225, AB=15.

Perimeter of ABC is AB+BC+CA=15+5*root(3)+10*root(3).

15(1+root(3))

4x - 5y = 15<br> find the slope and y-intercept
Mazyrski [523]

Answer:

slope=4/5

y-intercept = -3

Step-by-step explanation:

first we need to rewrite the expression to

y=mx+b

were b is the y-intercept and m the slope

4x-5y=15\\\\4x-5y+5y=15+5y\\\\4x+0=15+5y\\\\4x=5(3)+5(y)\\\\4x=5(3+y)\\\\\frac{1}{5}*4x= \frac{1}{5}*5(3+y) \\\\\frac{4x}{5}=3+y\\\\\frac{4x}{5} -3=3+y-3\\\\\frac{4x}{5} -3=y+0\\\\y=\frac{4x}{5} -3\\\\y=\frac{4}{5}x-3

so there we have it

m=\frac{4}{5} \\\\b=-3

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15
Norma-Jean [14]

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x
