Answer:
(a) 15/17
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the cosine relation:
Cos = Adjacent/Hypotenuse
cos(P) = PQ/PR
cos(P) = 15/17
3 5/9 divided by -2 2/3
change the mixed numbers to improper fractions
3 5/9 = (9*3+5)/9 = 32/9
-2 2/3 = -(3*2+2)/3 = -8/3
32/9 divided by -8/3
copy dot flip
32/9 * -3/8
-96/72
divide top and bottom by 24
-4/3
=-1 1/3
Answer: - 1 1/3
Answer:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Step-by-step explanation:
Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:
(1)
Where:
- Temperature, measured in degrees Fahrenheit.
- Temperature, measured in degrees Celsius.
If we know that 
, then its equivalent temperature on Celsius scale is:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Her final payment is 78$. Just do 50+52+54+56+58... and so on until you get up into the 1,100's. Then subtract that last number you got from 1200. The answer is 78.
Answer:
f(x) = (x+6)² - 10
Step-by-step explanation:
To write the equation in vertex form we, we need to use completing square method.
f(x) = x²+ 12x + 26 = (x² + 2*x*6 + 6²) - 6² + 26 = (x+6)² -36 + 26 =
= (x+6)² - 10
f(x) = (x+6)² - 10
