Answer:
x ≠ - 2, 5
Step-by-step explanation:
The restrictions occur in the denominator which cannot be zero as this would make the function undefined. Equating the denominator to zero and solving gives the values that x cannot be.
solve x² - 3x - 10 = 0 ⇒ (x - 5(x + 2) = 0 ⇒ x = -2, 5
Look at the digit to the right of the required number. If it is a 5 or greater, add 1 to previous digit.
If it is less than 5, leave the previous digit unchanged. In either case, drop all the remaining digits. Example: Round off this decimal 7.253896 to three decimal digits.
Answer. 7.253896approximately7.254
(The wavy equal sign approximately means "is approximately equal to.")
To round off to three decimal digits, we must look at the digit in the fourth place. The digit in the fourth place is 8 (greater than 5). Therefore, we add 1 to the previous digit 3.
<u>Step-by-step explanation:</u>
Here we have , cos x = -4/5 ( corrected as given -45 which is not possible ) ,
180° < x < 270° i.e. in third quadrant . We need to find tan(2x) . Let's find out:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
, since in third quadrant . remains same .
Now , 
⇒
⇒ 
⇒ 
⇒
Therefore, .
I believe the answer you looking for is Probability.
This means that if someone spinned that wheel, they have a probability of getting the color they need.
For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.
I hope this helps you understand!!

Y= 10 + 1.25x
This is the answer because 10 is the initial fee (you start with it) and 1.25 is added for each minute, with each minute being the variable
