Answer:
Step 1: Add 5 to both sides.
4(|−x+7|)−5+5>15+5
4(|−x+7|)>20
Step 2: Divide both sides by 4.
4(|−x+7|)÷4 > 20÷4
|−x+7|>5
Step 3: Solve Absolute Value.
|−x+7|>5
We know either−x+7>5 or −x+7<−5
−x+7>5(Possibility 1)
−x+7−7>5−7(Subtract 7 from both sides)
−x>−2
−x -1 > -2-1(Divide both sides by -1)
x<2
−x+7<−5(Possibility 2)
−x+7−7<−5−7(Subtract 7 from both sides)
-x-1 > -2-1( Divide both sides by -1)
x<2
−x+7<−5(Possibility 2)
−x+7−7<−5−7(Subtract 7 from both sides)
−x-1 < −12-1 (Divide both sides by -1)
x>12

Can someone help me please
Answer:
The set = {1, 2, 3, 4, 5}
Step-by-step explanation:
Let us explain how to solve this question
∵ The set = {x : x is a digit in the number 241,532)
→ That means the elements of the set are the digits of the given number
∴ The elements in this set are the digits of the number 241,532
∵ The digits of the number 241,532 are 2, 4, 1, 5, 3, 2
→ In any set of numbers,
Do not repeat any numberArrange the numbers∴ The elements of the set are 1, 2, 3, 4, 5
∴ The set = {1, 2, 3, 4, 5}

If you wrote 0.0009763 as a single digit times a power of ten, would the exponent be positive or negative?
The exponent would be negative because the original number is greater than one.
The exponent would be positive because the original number is greater than one.
The exponent would be negative because the original number is less than one.
The exponent would be positive because the original number is less than one.
Answer:
the exponent would be negative because the original number is less than one
Step-by-step explanation:
example: 0,1= 1.10^-1
The exponent would be negative because the original number is less than one. Option 3 is correct.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
0.0009763 can be written as a single-digit time power of ten by the following representation,
0.0009763 = 9.763×10⁻⁴
The power of the integer 10 is shown as the exponent. Here the value of the power of 10 is -4, as a result, the value of the exponent would be negative and it is due to the fact that the original number is less than one.
Thus, the exponent would be negative because the original number is less than one. Option 3 is correct.

The distance between -18 and 15 is equal to _____.
18 - 15
-18 - 15
15 - 18
15 - (-18)
Answer:
15 -(-18)
Step-by-step explanation:
a double negative is basically a + sign. The distance between -18 & 15 is 33, so 15- (-18) or 15 + 18 is 33 is equivalent

Let f be a differentiable function such that f(3) = 2.345 and f' (x) = ln (x^2+ 1). What is the value of f (5)?
A) 3.301
B) 5.631
С) 6.950
D) 7.976
Use a linear approximation to [tex]f(x)[/tex] centered at [tex]x=3[/tex]:
[tex]f(x)\approx f(3) + f'(3)(x-3)[/tex]
Then
[tex]f(5)\approx2.345+\ln(3^2+1)(5-3)\approx6.95[/tex]
which makes C the most likely choice.
Here we want to solve the differential equation, by finding the Taylor expansion of the function and evaluation we will find that f(5) = 6.950, so the correct option is C.
Taylor series the equation:Here we must start by doing a Taylor expansion of the function, remember that the Taylor expansion is given by:
f(x) = f(a) + f'(a)*(x - a) + ...
The series has more terms, but we can work with two to get an estimation, if we use a = 3 we get:
f(x) = f(3) + ln(3^2 + 1)*(x - 3) = 2.345 + ln(10)*(x - 3)
Now we evaluate this in x = 5 to get:
f(5) = 2.345 + ln(10)*(5 - 3) = 6.950
So the correct option is C.

A = ________________ ᵒ.
Answer:

Step-by-step explanation:
[tex] \sin 3A = \cos (A – 70ᵒ) \\ \\ \cos(90 \degree - 3A) = \cos (A – 70ᵒ) \\ \{\because \: \cos(90 \degree - \theta) = \sin \theta \} \\ \\ (90 \degree - 3A) = (A – 70ᵒ) \\ \\ 90 \degree + 70ᵒ = 3A + A \\ \\ 160 \degree = 4A \\ \\ A = \frac{160 \degree}{4} \\ \\ \huge \red{ \boxed{A = 40 \degree}}[/tex]

Write this number in scientific notation 38200000
Look at attachment down below
Answer:
3.82 × 107
Step-by-step explanation:
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.
Count how many places you moved the decimal point. This number is b.
If you moved the decimal to the left b is positive.
If you moved the decimal to the right b is negative.
If you did not need to move the decimal b = 0.
Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
Remove trailing 0's only if they were originally to the left of the decimal point.
What is a one-to-one function?
a. A function f is called a one-to-one function if it has negative slope.
b. A function f is called a one-to-one function if it is a vertical line.
c. A function f is called a one-to-one function if it never takes on the same value twice.
d. A function f is called a one-to-one function if it is a horizontal line.
e. A function f is called a one-to-one function if it periodically takes on the same value.
Answer:
C.
Step-by-step explanation:
A one to one function is a function in which an element in a domain is corresponding to the a single element in the range. That is, each element in the domain has exactly one image in the range.
To answer the question that say : What is a one-to-one function?
A function f is called a one-to-one function if it never takes on the same value twice.
Therefore the correct answer is option C.

Which polygon has an interior angle sum of 1080°?
A polygon has 8 sides.
A polygon has 10 sides.
A polygon has 9 sides.
A polygon has 7 sides.
Answer:
first answer A
Step-by-step explanation:
it's the only one that has 8 sides
For a polygon to have an interior angle sum of 1080°, number of its sides will be 8.
Option A) polygon has 8 sides is the correct answer.
What is a polygon?A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.
The formula for calculating the sum of interior angles of a polygon is;
S = ( n − 2 ) × 180°
Where n is the number of sides.
Given that;
The sum of the interior angles S = 1080°Number of sides n = ?We substitute the value of the sum into our above equation.
S = ( n − 2 ) × 180°
1080° = ( n − 2 ) × 180°
( n − 2 ) = 1080° / 180°
n − 2 = 6
n = 6 + 2
n = 8
Therefore, for a polygon to have an interior angle sum of 1080°, number of its sides will be 8.
Option A) polygon has 8 sides is the correct answer.
