Answer:
r = 33 , s = 18
Step-by-step explanation:
Rationalise the denominator by multiplying both numerator and denominator by the conjugate of the denominator.
The conjugate of 4 -
is 4 +
, then
← expand numerator/denominator using FOIL
= 
= 
= 
= 
with r = 33 and s = 18
Answer:
3, 8, and last one wont render for me
Step-by-step explanation:
Multiply 3 by every number going up and see which one is closest to 10 after being added with 2.
Its the same steps with the second question just different numbers.
Hope this helps
Branliest answer please if you don't mind
Answer: This would be expressed as: " (x + 2) / 8 " .
Answer:
The final price will be $12.67
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 14.9 × 15/100
Discount = 14.9 x 0.15
You save = $2.24
Final Price = Original Price - Discount
Final Price = 14.9 - 2.235
Final Price = $12.67
hope this helps and is right. p.s. i really need brainliest :)
Hello,
I would be happy to help.
For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3
Remember to use the order of operations!
Good luck,
