Answer to problem 5 is A) WU = ZX.
Notice how the angle U is between WU and VU. Similarly, angle X is beween ZX and XY
The order is very important. The angles must be between the two pairs of sides.

Answer to problem 6 is C) 15/17.
Use the pythagorean theorem to find the hypotenuse AC to be 17 units. Then take the ratio of the adjacent and hypotenuse to get the answer.

Answer to problem 7 is choice C
Use the rule cos(90-x) = sin(x) where x = 72-a
Answer:No
Step-by-step explanation:
Imagine 3 tablespoons they are big.
Answer:
She shouldn't tip at all since that's a ridiculous concept
Step-by-step explanation:
common sense
SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = <u>20</u>
now we need 20% of that so that's
20 * 0.2 = <u>4</u>
If she's simple-minded enough to tip that would amount to <u>$4</u>
Answer:
Option A) f(n)=-5-4n is correct.
The equation would produce the same sequence of numbers as the recursive formula is f(n)=-5-4n
Step-by-step explanation:
Given that a=-9 and ![a_{n}=a_{n-1}-4](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7Bn-1%7D-4)
The recursive formula is ![a_{n}=a_{n-1}+d](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7Bn-1%7D%2Bd)
Therefore d=-4
Let
and d=-4
We can find ![a_{2},a_{3},...](https://tex.z-dn.net/?f=a_%7B2%7D%2Ca_%7B3%7D%2C...)
![a_{2}=a_{1}+d](https://tex.z-dn.net/?f=a_%7B2%7D%3Da_%7B1%7D%2Bd)
![=-9-4=-13](https://tex.z-dn.net/?f=%3D-9-4%3D-13)
Therefore ![a_{2}=-13](https://tex.z-dn.net/?f=a_%7B2%7D%3D-13)
![a_{3}=a_{2}+d](https://tex.z-dn.net/?f=a_%7B3%7D%3Da_%7B2%7D%2Bd)
![=-13-4=-17](https://tex.z-dn.net/?f=%3D-13-4%3D-17)
Therefore
and so on.
Therefore the arithmetic sequence is ![{\{-9,-13,-17,...}\}](https://tex.z-dn.net/?f=%7B%5C%7B-9%2C-13%2C-17%2C...%7D%5C%7D)
Option A) f(n)=-5-4n is correct.
f(n)=-5-4n
put n=1 in f(n)=-5-4n
f(1)=-5-4(1)
=-9
Therefore f(1)=-9
put n=2 in f(n)=-5-4n
f(21)=-5-4(2)
=-5-8
Therefore f(2)=-13
put n=3 we get f(n)=-5-4n
f(3)=-5-4(3)
=-5-12
Therefore f(3)=-17 and so on .
Therefore the sequence is ![{\{-9,-13,-17,...}\}](https://tex.z-dn.net/?f=%7B%5C%7B-9%2C-13%2C-17%2C...%7D%5C%7D)
Therefore the equation would produce the same sequence of numbers as the recursive formula is f(n)=-5-4n
