Answer:

D

Step-by-step explanation:

A sin 2.355/2.355  =0.01745240644 cos -2.355/2.355 root square

=180 so untrue not-1

B. sin =0.01745240644 cos = 0 so untrue not 1.

C sin = 0.01745240644 cos = 180 so untrue not 1

D = - 2.355/2.355= 0.01745240644  cos = 0.01745240644 = -1 so true.

As if we divide 1 into -1 = 1

When we divide  0.01745240644 / 0.01745240644 = will also = 1

The answer is -1 as inverse.

A restaurant offers a​ $12 dinner special that has 77 choices for an​ appetizer, 1010 choices for an​ entrée, and 44 choices for
krok68 [10]
<span>280 I'm assuming that this question is badly formatted and that the actual number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts. So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre, so the number of possible meals to this point is n = 7 * 10 = 70 Finally, you finish off with a dessert, so the number of meals is: n = 70 * 4 = 280 Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is n = 77 * 1010 * 44 = 3421880 But I believe that it's highly unlikely that the numbers in this problem are correct. Just imagine the amount of time it would take for someone to read a menu with over a thousand entres in it. And working in that kitchen would be an absolute nightmare.</span>

Which of the following describes the graph of y = x² - 225?
lara [203]

Answer:

option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.

Step-by-step explanation:

we have

y=x^{2} -225

This is the equation of a vertical parabola open upward (the leading coefficient is positive)

The vertex represent a minimum

The vertex is the point (0,-225)

The axis of symmetry is x=0 (y-axis)

Find the x-intercepts (values of x when the value of y is equal to zero)

For y=0

0=x^{2} -225\\x^2=225

square root both sides

x=\pm15

therefore

The graph has zeroes at x = 15 an x = -15 and it opens upward.

Sindrei [870]
In geometry, the circumference (from Latin circumferences, meaning "carrying around") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle The area of a circle is pi (approximately 3.14) times the radius of the circle squared.

Gem and her three friends are going on a holiday. There is a buy 2 get one free offer on plane tickets. Tickets cost £600 each.
VLD [36.1K]

Answer: £450

Step-by-step explanation:

If they bought 2 tickets, they could get an extra ticket for free. As there are three of them, they would buy 2 tickets, get one for free and then buy another ticket to make it four.

In that case they would have only paid for 3 tickets.

The total cost of 3 tickets is:

= 600 * 3

= £1,800

The 4 of them would therefore have to pay:

= 1,800 / 4

= £450
