Answer: 9.5 (D.)

Step-by-step explanation:

SOCAHTOA

the sin of an angle is equal to the opposite side over the hypotenuse.

angle: 32

opposite side: x

hypotenuse: 18 m

1. sin32 = x/18

2. 18(sin32) = x

3. 9.5 = x

if you are confused with how it went from 18(sin32) to 9.5, you can plug 18(sin32) into your calculator.

Answer:

30 cm

Step-by-step explanation:

The first one it says 4cm. That means all sides equal to 4 cm.

The second one it says 5 cm. That means all sides equal to 5 cm.

Lets do the second shape.

Since you see 6 sides with 5cm.

You do 6 times 5. Which equals to 30.

You add the label, so 30cm.

What is the greatest number that rounds to 500 when rounded to the nearest ten?

Answers

Answer:

504.999...

Step-by-step explanation:

505 rounds to 510, but a number that is infinitessimally smaller rounds to 500.

Unfortunately, for any number you can write that rounds to 500, there are an infinite number of numbers that are greater and still less than 505.

In short, there is no "greatest number" that is less than 505—unless you put additional restrictions on it, like the number of digits that can be used to express it, for example.
i believe the answer is 549.

Answer:

x = ln 10

Step-by-step explanation:

You meant e^x - 1 = 9.  Let's isolate e^x, by adding 1 to both sides.  We get:

e^x = 10

Now make use of the property ln a = b  <=> a = e^b

Then e^x = 10 becomes  

x = ln 10

A standard​ 52-card deck has four​ 13-card suits:​ diamonds, hearts,​ clubs, and spades. the diamonds and hearts are​ red, and the clubs and spades are black. each​ 13-card suit contains cards numbered from 2 to​ 10, a​ jack, a​ queen, a​ king, and an ace. an experiment consists of drawing 1 card from the standard deck. find the probability of drawing a black king of heartsblack king of hearts.

Answers

The probability of getting a black king of hearts is 1/52

From the question, we have:

The number of cards in a standard deck, n = 52

Black king of heart, r = 1

The probability of getting a black king of hearts is the quotient of the number of black king of heart and the total number of cards in the deck.

So, we have:

p = 1/52

Hence, the probability of getting a black king of hearts is 1/52

Find two positive numbers such that the sum of the first and twice the second is 200 and their product is a maximum.

Answers

Answer:

20 and 90

Step-by-step explanation:

20 + 2(90) = 200

20 + 180 = 200

200 = 200

20 × 2(90)

= 20× 180

= 3,600

A ball is thrown straight out at 80 feet per second from an upstairs window that's 15 feet off the ground. It turns out that its motion can be broken down into its motion in the x-direction (horizontally) and its motion in the y-direction (vertically), and that those two components can be thought of completely independently. In other words, its horizontal motion has no influence on its vertical motion, and vice versa. I've written the two component functions here: x(t) is its position in the x-direction, and y(t) is its position in the y-direction. Which of the following choices is correct? (Ignore air resistance.) NOTE: Use a reference frame that makes all positions (x and y coordinates) of the projectile positive.
