The domain of the function given are:
y=cot x
{x∈R: πn<x<π(n+1)} where n any integer

y=csc x
{x∈R: πn<x<π(n+1)} where n any integer

y=cos x

R (all real numbers)

y=sec x

{x∈R:π(n+1/2)<x<π(n+3/2)} where n is all integers.

from above we see that the the function that has a domain of all real numbers except npi is y=cot x and y=csc x

The solutions to a certain quadratic equation are x = -4 and x = 3. Write the equation in standard form below.

saw5 [17]

Answer:

$x^2 + x -12$

Step-by-step explanation:

If the solutions are x=-4 and x=3, then it must have factors (x+4)(x-3). Assuming there is no GCF or leading coefficient other than 1, multiply with FOIL to find the standard form.

$(x+4)(x-3)\\x^2 + 4x -3x -12\\x^2 + x -12$

Please help for 10 ponits

Vedmedyk [2.9K]

Answer:

it's a yes

Step-by-step explanation:

X/6 ≤ 30

to find the value of X we have to move the numerical to the other side

in this case the number is 1/6

X * 1/6 ≤ 30

so to balance the both side and get rid of the number on the left side we multiple with 6.

1/6*6 = 1 on the left side

30*6 = 180 on the right side

so the full equation will be

X * 1/6 * 6 ≤ 30 * 6

X * 1 ≤ 180

X ≤ 180

A pharmacist is trying to stock the pharmacy with cheaper alternatives for customers. She will stop carrying the more expensive

raketka [301]

Answer : C. Caplet form is the most expensive.

Tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets.

50 mg of 100 tablets so 50 * 100 = 5000mg

5000mg cost = $75.00

So 1mg of tablet form cost = $\frac{75}{5000}$ = 0.015

Capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85 capsules

75 mg of 85 capsules, so 75 * 85 = 6375mg

6375mg cost = $63.75

So 1mg of Capsule form cost = $\frac{63.75}{6375}$ = $0.01

Caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets

100 mg of 40 caplets , so 100 * 40 = 4000 mg

4000mg cost = $70.00

So 1mg of Caplet form cost = $\frac{70}{4000}$ = $0.0175

Caplet form is the most expensive.
