Find the coordinates of the point (x,y) at the given angle θ on a circle of radius r centered at the origin. Show all work. Roun

beks73 [17]

Answer:

(i) The equivalent coordinates in rectangular form are $(x, y) = (-3.277,-2.294)$ .

(ii) The equivalent coordinates in rectangular form are $(x, y) = (0.866, 0.5)$ .

Step-by-step explanation:

In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:

$(x, y) = (r\cdot \cos \theta, r\cdot \sin \theta)$

Where:

$r$ - Norm of vector, dimensionless.

$\theta$ - Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.

(i) ( $r = 4$ , $\theta = 215^{\circ}$ )

$(x. y) = (4\cdot \cos 215^{\circ}, 4\cdot \sin 215^{\circ})$

$(x, y) = (-3.277,-2.294)$

The equivalent coordinates in rectangular form are $(x, y) = (-3.277,-2.294)$ .

(ii) ( $r = 1$ , $\theta = 30^{\circ}$ )

$(x. y) = (1\cdot \cos 30^{\circ}, 1\cdot \sin 30^{\circ})$

$(x, y) = (0.866, 0.5)$

The equivalent coordinates in rectangular form are $(x, y) = (0.866, 0.5)$ .

What are the x-intercepts of the graph of the function f(x) = x2 + 5x − 36?

Ede4ka [16]

Answer: Second option: (4,0) and (-9,0)

f(x)=x^2+5x-36

The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0

Factoring the polynomial:
(x+9)(x-4)=0

Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4

x+9=0 or x-4=0

Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4

Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)

Repeat Part A for the situation where Mari’s lemonade stand makes a proﬁ t (meaning she has enough money to pay for her startup

zalisa [80]

Mari must sell more than 36 cups of lemonade to make profit

<h3>How to draw the number line?</h3>

The complete question is added as an attachment

From the question, we have:

Start up cost = $18

Let the amount per cup of lemonade be $0.5, and the number of cups be x

So, the total amount in sales is:

Total = 0.5 * x

Evaluate

Total = 0.5x

When Mari’s lemonade stand makes a proﬁt, we have:

Total sales > Start up cost

This gives

0.5x > 18

Divide both sides by 0.5

x > 36

Hence, Mari must sell more than 36 cups of lemonade to make profit
