How do I solve this problem?​

Answers

Answer:

Step-by-step explanation:

The first 2 pieces of this function agree at pi/4, so we will set them equal to each other and sub in pi/4 for x to solve for k:

[tex]ksin(\frac{\pi}{4})+(\frac{\pi}{4})^2=\frac{\pi}{4}+2[/tex] and

[tex]k(\frac{\sqrt{2} }{2})+\frac{\pi^2}{16}=\frac{\pi}{4}+2[/tex] and we'll multiply everything by 16 to get rid of the fractions. Doing that gives us:

[tex]8k\sqrt{2}=4\pi+32-\pi^2[/tex] and

[tex]k=\frac{4\pi+32-\pi^2}{8\sqrt{2} }[/tex] so

k = 3.067

The next one is a bit tricky if you're not up on your natural log equations.

Again, we set these equal to each other because they meet at the value of e. We sub in e for x and solve for m:

[tex]x +2=mlne^x[/tex]

We'll sub in e for x. ln of e to the x power is equal to x, so

e + 2 = me and

[tex]m=\frac{e+2}{e}[/tex] so

m = 1.736

Answers

Answer:

3x - 6

Step-by-step explanation:

To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)

f(2x) = 3(2x) - 2 = 6x - 2

f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4

Thus

f(2x) - f(x + 2)

= 6x - 2 - (3x + 4)

= 6x - 2 - 3x - 4

= 3x - 6

Step-by-step explanation:

Let

Then

10x = 37.777.....             (2)

Subtracting (1) from (2)

10x - x = 37.7777..... - 3.77777.......

4 is = 2^2 so we can change 4^4 to 2^8.

(2^(2*4)).

The answer isn't in the options anyway I'll write it. the answer is 46.

Step-by-step explanation:

According to BODMAS rule - addition should be done first so

4+36= 40 and -3 +7 = 4 so 40+4 ,= 44

then we should do subtracting so, 10-8 = 2

to conclude we should bring the equation to an end so,

During a backgammon game, Jimmy rolled two dice on the board. Find the probability that the sum obtained was greater than 8 given that the number on one die was a 6

Answers

Answer:

2/3

Step-by-step explanation:

This problem bothers on probability

Given that two dice are expected to give an outcome of sum greater than 8

But in the problem statement the first die is already settled since it is showing 6 already.

Now for the second die, the possible outcomes that will add up with the first die to produce a figure greater than 8 are (3,4,5,6)  

The probability of obtaining either of these numbers is 4/6= 2/3

Having the first die settled, this means that the probability of obtaining a sum of 8 is 2/3

The Midpoint of UV is M(4, -6). Find V given U(7, -9)

Answers

Answer:

(1, -3)

Step-by-step explanation:

Given the Midpoint of UV is M(4, -6) and U(7, -9), we are to find the other coordinate V. The formula for calculating the midpoint of two coordinates is expressed as shown;

M(X,Y) = (x1+x2/2, y1+y2/2)

X = x1+x2/2

Y = y1+y2/2

Given (X,Y) = ()4, -6)

U (x1, y1) = (7, -9)

To get x2 and y2, we will substitute the given values into th formula above;

4 = (7+x2)/2

cross multiply

4*2 = 7+x2

8 = 7+x2

x2 = 8-7

x2 = 1

Similarly for y2;

-6 = (-9+y2)/2

cross multiply

-6*2 = -9+y2

-12 = -9+y2

y2 = -12+9

y2 = -3

Hence the other coordinate V(x2, y2) is (1, -3)

what is equivalent to 3x-4-(5x+7)

Answers

-2x-11 is equivalent to 3x-4-(5x+7)
Easy, so here’s what you do, take care of the parenthesis so it looks like 3x-4 because the negative is disturbed to make the positive 5x a negative and the positive 7x into a negative, a good pointer is anytime you’re multiplying two signs, a good thing to know is if the signs are different, it’s negative, if they’re the same, they’re positive. Now you want to move the negative 5x to the left of the +3x so you should see -5x+3x-4-7 so from here, you want to add the -5x to the 3x to get you -2x so now you should have -2x-4-7 then subtract the 4 from the seven or the seven from the four looking like 4-7 to get you -11 so now you should have
