3+(55-111)/25 equals what
Answer:
0.76
Step-by-step explanation:
3+(55-111)/25
=3+(-56)/25
=3+ (-2.24)
=0.76
Answer:
3+(55-111)/25= 0.76
Step-by-step explanation:
Using PEMDAS, you solve 55-111 which is -56
Then you divide -56 by 25 because it is the fourth step, you get -2.24
Add three to -2.24 to get 0.76
If you round UP to the nearest tenth, it will be 0.80
If you round DOWN to the nearest tenth, it will be 0.70

Form an equation and solve it to answer the question. An editor needs to read a 700-page manuscript. Her goal is to proofread 28 pages each day. If she has already read 112 pages, how many more days will it take her to complete the proofreading?
Answer:
21 more days
Step-by-step explanation:
Let x be the number of days
700-112 = 28x
588 = 28x
x = 21
It will take her 21 more days

Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.) xe9x dx; u
Answer:
The answer is "[tex]\bold{\frac{ \ e^{9x}}{9} (x-1)+C}\\[/tex]"
Step-by-step explanation:
Taking the integral [tex]\int x^{2x} \ dx[/tex]
Evaluating the integral by using integration:
[tex]u=x\\\\dv=e^{9x} \ dx[/tex]
Let
[tex]u=x\\\\ dv=e^{9x} dx[/tex]
Then,
[tex]\to \frac{du}{dx}= 1 \ and\ v =\int e^{9X} \ dx \\\\\to du = 1 \ dx \\\\\to v = \frac{e^{9x}}{9}\\\\\text{integrate the above value}:\\\\\int\ u \ dv = uv - \int v du \\\\Now, \\\\\to \int x e^{9X} \ dx = x \frac{e^{9x}}{9} - \int \frac{e^{9x}}{9} dx[/tex]
[tex]= \frac{ x \ e^{9x}}{9} - \frac{e^{9x}}{9}\\\\= \frac{ \ e^{9x}}{9} (x-1)+C\\[/tex]
Answer:
[tex]\displaystyle \int {xe^{9x}} \, dx = e^{9x} \bigg( \frac{x}{9} - \frac{1}{81} \bigg) + C[/tex]

Answer:
f(1) = - 1
f(-1) = - 2
Step-by-step explanation:
f(1) will lie in the function f(x) = - 2x + 1
Therefore,
f(x) = - 2x + 1
Plug x = 1
f(1) = - 2*1 + 1 = - 2 + 1 = - 1
f(-1) will lie in the function f(x) = - x - 1
Therefore,
f(x) = - x - 1
Plug x = - 1
f(-1) = - 1 - 1 = - 2
Answer:
-1, 0, 1, 11, 3Step-by-step explanation:
Function 1
f(x) = -2x + 1f(1) = -2(1) + 1 = -2 + 1 = -1Function 2
f(x) = -x - 1f(-1) = -(-1) - 1 = 1 - 1 = 0Function 3
f(x) = x + 3f(-2) = -2 + 3 = 1Function 4
f(x) = 2x + 1f(5) = 2(5) + 1 = 11Function 5
