This isn't one of your answer choices though.
How do I solve this problem?
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
Hope that helps!
What is the value of x in the equation -x = 6 - 3x + 8?

Simplify
2x=14
Simplify
x=7
F(x)=3x-2
Simplify F(2x)-F(x+2)
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

Which of the following statements must be true about a parallelogram?
Answer:C
Step-by-step explanation:
write 3.777777 as a fraction
Answer:
[tex]\huge\boxed{\sf \frac{34}{9}\ \ OR \ \ 3\frac{7}{9} }[/tex]
Step-by-step explanation:
Let
x = 3.777....... (1)
Then
10x = 37.777..... (2)
Subtracting (1) from (2)
10x - x = 37.7777..... - 3.77777.......
9x = 34
Dividing both sides by 9
x = 34 / 9
x = [tex]3 \ \frac{7}{9}[/tex]
[tex]\rule[225]{225}{2}[/tex]

i’m so confused???
2^5*2^3/4^4 plz answer
Answer:
1
Step-by-step explanation:
Because they both of the same base, we can merge 2^5 and 2^3 into one term: 2^8 (2^(3+5))
4 is = 2^2 so we can change 4^4 to 2^8.
(2^(2*4)).
Thia means we now have 2^8/2^8 which is 1.
As anything divided by itself is just 1.
Hope this helped!

1. Simplify the expression:
4+36+(10-8)’-3+7
A. 130
B. 100
C. 38
D. 37
Answer:
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,
44+2 = 46
HOPE THIS HELPS YOU
What is the slope of the line that passes through these two points? (-3,4) (5,4)
Answer:
0
Step-by-step explanation:
To find the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
= ( 4-4)/( 5 - -3)
= 0/ ( 5+3)
= 0/8
= 0
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
Answer:
2/3Step-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

Step-by-step explanation:
The Midpoint of UV is M(4, -6). Find V given U(7, -9)
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)
Solve for x:
-2 (x -4) - 1/2 (3-4x) = -12
Answer:
No solution for xStep-by-step explanation:
-2 (x -4) - 1/2 (3-4x) = -12
×(-2) ×(-2)
4(x - 4) + (3 - 4x) = 24
4x - 16 + 3 - 4x = 24
-13 = 24 <-- it's not true so it's no solution

On a map, 1cm represents 65 km. If two cities are 1950 km apart, how many centimeters apart would they be on this map?
Answer:
30 cm.
Step-by-step explanation:
We can solve this problem by making a proportion:
1 cm/65 km = x cm/1,950 km
By cross-multiplying, we can solve for x:
65x = 1,950
x = 30

7x-3y= 6; х= 3
Answer:
If you are looking for y it's 5
Step-by-step explanation:
Plug in 3 for x
7(3) -3y = 6
21 - 3y = 6
subtract 21 from both sides
-3y = - 15
divide by three from both sides
y = 5

Answer:
C. 490.
Step-by-step explanation:
25% = 0.25.
If the number of emails that Ryan and Taylor each received is x emails then Sara received 2x + 0.25 * 2x = 2.5 emails.
So 2x + 2.5x = 882
x = 882/4.5
x = 196.
So Sara received 2.5 * 196
= 490 emails.

Solve for x.
X^2-6x+10=2
Answer:
x = 2, 4
Step-by-step explanation:
Step 1: Write out quadratic
x² - 6x + 10 = 2
Step 2: Subtract 2 on both sides
x² - 6x + 8 = 0
Step 3: Factor
(x - 4)(x - 2) = 0
Step 4: Find roots
x - 4 = 0
x = 4
x - 2 = 0
x = 2

Write an equation to describe the relationship between x and y.
Answer:
y = 4.5x
Step-by-step explanation:
Given:
x= 2 ⇒ y=9x=5 ⇒ y=22.5x=8 ⇒ y=36We can see that:
9/2 = 22.5/5 = 36/8 = 4.5Therefore the relationship between x and y is:
