The polar form of (-1,√3) is(___,___)

Mathematics
1 answer:
Klio2033 [76]3 years ago
4 0

Answer:

(2, 2/3 * pi)

Step-by-step explanation:

( -1, sqrt(3))

to find the radius

sqrt(x^2 + y^2) = r

sqrt( (-1)^2 + (sqrt3)^2) = r

sqrt(1+3) =r

sqrt(4) =r

2=r


to find theta

theta = arctan (sqrt(3)/-1)

theta = -60 degrees

you need theta between 90 and 180

add 180 to theta

theta = 120


you need theta in radians

120 * pi/180 = 2/3 * pi

Dr. Gonzalez is considering joining the Garden Club. If he pays a $25 membership fee, he
ziro4ka [17]

Answer:

In the Garden Club the cost will be a fixed fee of $25 and $10 for each rosebush, so if he buys X rosebushes, the total cost will be:

C1(X) = $25 + $10*X

While in the local nursery there is no initial cost, and each rosebush costs $15, so if he buys X rosebushes, the total cost will be:

C2(X) = $15*X

Now, let's find the value of X where C1 and C2 are equal, this is:

$25 + $10*X = $15*X

$25 = $15*X - $10*X = $5*X

X = 25/5 = 5

This means that if he buys 5 rosebushes, he will pay the same amount in both places.

If he buys less than 5 rosebushes, he will pay less in the local nursery (as it has a bigger slope, but no initial fee)

If he buys more than 5 rosebushes, he will pay less in the Garden club (because it has a smaller slope)
