Answer:

63

Step-by-step explanation:

First, I wrote the fraction as 1 63/100. I believe this is simplest form so the numerator is 63.

Given f(x) =
sergejj [24]

Answer:

A

Step-by-step explanation:

We are given the function:

\displaystyle f(x) = \left\{        \begin{array}{ll}            2\cos(\pi x) \text{ for }  x \leq -1 \\ \\          \displaystyle   \frac{2}{\cos(\pi x)}\text{ for } x > -1        \end{array}    \right.

And we want to find:

\displaystyle \lim_{x\to -1}f(x)

So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.

Left-Hand Limit:

\displaystyle \lim_{x\to-1^-}f(x)

Since we are approaching from the left, we will use the first equation:

\displaystyle =\lim_{x\to -1^-}2\cos(\pi x)

By direct substitution:

=2\cos(\pi (-1))=2\cos(-\pi)=2(-1)=-2

Right-Hand Limit:

\displaystyle \lim_{x\to -1^+}f(x)

Since we are approaching from the right, we will use the second equation:

=\displaystyle \lim_{x\to -1^+}\frac{2}{\cos(\pi x)}

Direct substitution:

\displaystyle =\frac{2}{\cos(\pi (-1))}=\frac{2}{\cos(-\pi)}=\frac{2}{(-1)}=-2

So, we can see that:

\displaystyle \displaystyle \lim_{x\to-1^-}f(x)=\displaystyle \lim_{x\to -1^+}f(x) =-2

Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:

\displaystyle \lim_{x \to -1}f(x)=-2

Our answer is A.

Graph the six terms of a finite series where a1 = -3 and r = 1.5.
zavuch27 [327]
A1 is the 1st term 
r is the difference, they can say "r" or "d" for the difference 

1st a1 is the first term = -3
2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5
the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d 
a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th 
d --> difference 
so to get the 2nd-->    -3+(2-1)*1.5= -1.5
to get the 3rd -->        -3 +(3-1)*1.5 = 0 
<span>and so on </span>

Math question<br>5x-5 (6*7x)=65
hammer [34]

5x-5(6\cdot7x)=65\\\\5x-5(42x)=65\\\\5x-210x=65\\\\-205x=65\qquad\text{divide both sides by (-205)}\\\\x=-\dfrac{65}{205}\\\\x=-\dfrac{65:5}{205:5}\\\\\boxed{x=-\dfrac{13}{41}}

Which statement about the ordered pairs (2, −9)(2, −9) and (3, −6)(3, −6) is true for the equation 5x−y3=135x−y3=13 ?
dedylja [7]
5x - y³ = 135x - y³ = 13
The answer can be obtained by simply putting the ordered pair into the equations. First (2 , -9)
5(2) - (9)³ = 135(5) - (-9)³ = 13
10 + 729 = 675 + 729 = 13
739 = 1404 = 13
This is not true. Therefore this is not a solution
Second (3,-6)
5(3) - (-6)³ = 135(5) - (-6)³ = 13
231 = 891 = 13
This is also not true
Therefore, neither ordered pair is a solution.
