Answer:
y= - 1/2 +2
Step-by-step explanation:
One, the slope is negative, so you can cross some answers out right off the bat. Other than that, the answer is not a whole because it's not that steep. If you use RISE/RUN you can tell its a -1/2. Plus, the y-intercept is 2!
i hope this helps!!
Answer:
2.5896
Explanation:
Zero power rule: The zero exponent rule states that any number raised to a power of zero equals one.
10^0 is 1, so nothing changes
A varible represents the number u are looking for.
Example:
2x + 3x
Answer:
See below in bold.
Step-by-step explanation:
(1) cosec ( x + 10) = 3
Now cosec x = 1/sin x so
1 / sin (x + 10) = 3
3 sin (x + 10) = 1
sin (x + 10) = 1/3
x + 10 = 19.47 , 160.53 degrees
x = 9.47, 150.53 degrees.
(ii) cot (x - 30) =0.45
cot (x - 30)= 1 /tan (x- 30) so we have
tan (x - 30) = 1 / 0.45 = 2.2222
x - 30 = 65.77 degrees
x = 95.77 degrees.
(40×5)+(2×5) so 40×5=200 and 2×5=10 so 200+10=210
