Romashka [77]3 years ago

Answer:

\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}

Step-by-step explanation:

if \sec x = \frac{4}{3}, then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.

The other leg (specifically the opposite one) will be equal to \sqrt{16-9} = \sqrt{7} by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = \frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}.

cot(x) is defined as adjacent over opposite, which is equal to \frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}

That means that the first option, the leftmost one, is correct.

Slope and y intercept y=7/4x-10
Andreas93 [3]

Hi there!

The slope is the number in front of x so it is 7/4 or 1 3/4

The y-intercept is the independent number in the equation, so it is -10

forsale [732]

Answer:

495.6

Step-by-step explanation:

18% of 420 is 75.6. Multiply that by 63 to get 4762.8. 420 multiplied by 63 equals 26460. 26460 plus 4762.8 is 31222.8. 31222.8 divided by 63 is 495.6. So the answer is $495.60 per year.

Children's tickets to a local play cost $\$1.50$ less than adult tickets. At one performance 325 children tickets and 175 adult
svetoff [14.1K]

Answer:

  $8.00

Step-by-step explanation:

The problem statement gives two relations between the prices of two kinds of tickets. These can be used to write a system of equations for the ticket prices.

__

<h3>setup</h3>

Let 'a' and 'c' represent the prices of adult and children's tickets, respectively. The given relations can be expressed as ...

  a - c = 1.50 . . . . . . . adult tickets are $1.50 more

  175a +325c = 3512.5 . . . . . total revenue from ticket sales.

__

<h3>solution</h3>

We are only interested in the price of an adult ticket, so we can eliminate c to give one equation we can solve for 'a'. Using the first equation, an expression for c is ...

  c = a -1.50

Substituting that into the second equation, we have ...

  175a +325(a -1.50) = 3512.50

  500a -487.50 = 3512.50 . . . . . . simplify

  500a = 4000 . . . . . . add 487.50

  a = 8 . . . . . . . . . divide by 500

An adult ticket costs $8.
