Convert r=53sinθ−cosθ to rectangular form.
Helga [31]

Answer:

y = \frac{1}{3} x + \frac{5}{3}

Step-by-step explanation:

r = 5/(3sinθ-cosθ)

multiply both sides by (3sinθ-cosθ):

r(3sinθ-cosθ) = 5

expand:

3rsinθ-rcosθ = 5

replace rsinθ with y and rcosθ with x:

3y-x = 5

add x to both sides:

3y = x + 5

divide both sides by 3:

y = 1/3x + 5/3

Dr potter provides vaccinations against polio and measles. Each polio vaccination multi-dose vial consists of 44 individual dose
never [62]

Answer: b) (32,28)


Step-by-step explanation:

Let x be the number of polio individual doses and y be the number of each measles  individual doses.

Then the number of polio vaccination  = 44x

The number of measles  vaccination multi-dose = 22x

According to the question,

x+y=60....(1)\\44x+22y=2024.....(2)

Dividing 22 on equation (2) both sides, we gwt

2x+y=92....(3)

Subtract (1) from (3), we get

x=32

Substitute x=32 in equation (1), we get

32+y=60\\\Rightarrow\ y=60-32\\\Rightarrow\ y=28

Hence, Dr. Potter gives 32 individual polio vaccination and 28 individual measles vaccinations .
