Graham and Hunter are circus performers. A cable lifts Graham into the air at a constant speed of 1.5 ft/s. When Graham’s arms are 18 ft above the ground, Hunter, who is standing directly underneath Graham, throws Graham a ball as the cable continues to lift him higher. Hunter throws the ball from a position 5 ft above the ground with an initial velocity of 24 ft/s. Which system of equations can be used to model this situation?

Multiply: (4x – 7)(2x – 9)

Answers

Hello there!

Let's use foil.

First: 4x * 2x = 8x^2

Outside: 4x * -9 = -36x

Inside: -7 * 2x = -14x

Last: -7 * -9 = 63

Now, let's combine these.

8x^2 - 36x - 14x + 63

Finally, we can simplify this

8x - 50x + 63

I hope I helped!

Let me know if you need anything else!

Which method used to calculate finance charges is most favorable to the card issuer?a.
adjusted balance
b.
average daily balance
c.
previous balance
d.
usual balance

Answers

Answer: c. previous balance method

The method used by credit card companies to calculate finance charges in which it is most favorable to the card issuer is the previous balance method. This is computed by charging the interest into the new billing period. This is least favorable to cardholder thus, most favorable to card issuer.

Answer:

usual balance

PLEASE ANSWER ASAP!!! TIMED!!Finding which number supports the idea that the rational numbers are dense in the real numbers?

A. a fraction between π/2 and π/3
B. an integer between –11 and –10
C. a whole number between 1 and 2
D. a terminating decimal between –3.14 and –3.15

Answers

Using the concept of dense numbers, it is found that the correct option is:

A. a fraction between π/2 and π/3

-----------------

The rational numbers are dense in the real numbers because all irrational numbers can be closely approximated to a rational.
There are no integers between -11 and -10, neither there are whole numbers between 1 and 2, thus, options B and C are incorrect.
Terminating decimals between -3.14 and -3.15, such as -3.141, are rational numbers, so it does not show the density, and thus, option D is incorrect.
$(\pi)/(2)$ and $(\pi)/(3)$ , just as $\pi$ , are non-terminating decimals, thus they are irrational numbers. However, through rounding, all can be approximated to a rational number, and thus, it shows that rational numbers are dense in the real numbers, being the correct option.

A similar problem is given at brainly.com/question/17405059

Answer:

A terminating decimal between -3.14 and -3.15

Step-by-step explanation:

A natural number includes non-negative numbers like 5, 203, and 18476.

It is encapsulated by integers, which include negative numbers like -29, -4, and -198.

Integers are further encapsulated by rational numbers, which includes terminating decimals like 3.14, 1.495, and 9.47283.

By showing a terminating decimal between -3.14 and -3.15, you are showing that rational numbers include integers (because integers include negative numbers)
