Answer:
c
Step-by-step explanation:
.
The first one is of order 5, so it has either 1, 3 or 5 real roots (unless any coefficent was complex). Proof complete :)
The other one, if it has a solution, it must be in [-1;1]. Because it only gives positive results the solution is further restricted to [0;1]. Because the cosine function is continuous and strictly decreasing on this interval, the difference of x and it's cosine will shrink up to some point within the interval where it gets to 0 (the solution) and then flips sign (the cosine gets less than the number), further decreasing until the end of the interval.
The answer is right on the Wi-Fi and blue on the other
Answer: 261
Step-by-step explanation:
You use PEMDAS to solve this problem
you first do the Parenthesis (p)
33+6(2+36)
33+6 (38)
We then multiply first (M)
33 + 6(38) - we know that 8 times 6 is 48 ; 6 times 3 is 18 +4 because we brought down the 4 from 48 to 3. which will be equal to 228
33 + 228
261
