Answer:
16
Step-by-step explanation:
Square root of 2 is irrational. This has been proven by the Pythagoreans (there is a simple proof of that).
pi is also known to be irrational although the proof is a bit more demanding.
Square root of 10 can be written as a product of square root of 5 and square root of 2, which themselves are irrational. Any product involving an irrational number is irrational
Square root of 16 = 4. 4 can be written as a fraction 4/1, or 8/2, 16/4, etc. and therefore is rational by definition.

Find the range of f(x)=-2x-5 for the domain {-2,-1,1,2}.
A. {-1,-3,-7,-9}
B. {-1,-3,3,5}
C. {-1,-3,7,9}

Answers
Answer:
A. {-1, -3, -7, -9}
Step-by-step explanation:
Plug all 4 points into the equation -2x-5.
-2(-2) - 5 = 4 - 5 = -1
(-2, -1)
-2(-1) - 5 = 2 - 5 = -3
(-1, -3)
-2(1) - 5 = -2 - 5 = -7
(1, -7)
-2(2) - 5 = -4 - 5 = -9
(2, -9)
The y-values make up the range, making the answer A, {-1, -3, -7, -9}
Answer:
A. {-1,-3,-7,-9}
Step-by-step explanation:
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}

Answer:
{-1, -3, -7, -9} is the range of the function f(x)
Step-by-step explanation:
Domain is the set of all complete possible values of x variable.
Range is the set of all values of f(x)
Given the function:
.....[1]
Domain: {-2, -1, 1, 2}
For x = -2,
Substitute in [1] we have
Similarly ,
For x = -1
For x = 1:
For x = 2
Therefore, the range of f(x) = {-1, -3, -7, -9}
Consider the function f(x) =
- 4x2xs-1
-3-*-1, *> -1
Which statement explains the continuity of the function at x = -1?
Because lim f(x) = 4 and f(-1) = 4, it follows that lim f(x) = f(-1). Therefore, the function is continuous at x

Ashin has been working in UAE for a decade and saved AED 125,500 which he wants to transfer now to his parent's account in India. Keeping in mind the AED – INR exchange rate for the day, which is AED 1 = 20 (approx.), find the amount of money which Arshad's parents will withdraw in India.
Answers
Answer:
2510000 INR
Step-by-step explanation:
Given
[tex]Savings = AED 125500[/tex]
[tex]1\ AED =20\ INR[/tex]
Required
The amount that will be withdrawn in India
We have:
[tex]1\ AED =20\ INR[/tex]
Multiply both sides by the savings
[tex]125500 * 1\ AED =20\ INR * 125500[/tex]
[tex]125500\ AED =125500 * 20\ INR[/tex]
So, we have:
[tex]125500\ AED =2510000\ INR[/tex]
Hence, the amount that will b withdrawn is: 2510000 INR

Answer:
m∠A = 120°
m∠C = 45°
Step-by-step explanation:
all triangle angles add up to 180
(12x + 12) + 15 + (3x +18) = 180
15x + 45 = 180
15x = 135
x = 9
m∠A = (12x + 12) = 12(9) + 12 = 120
m∠C = (3x +18) = 3(9) + 18 = 45

Answers
Answer:
s = 17 inches
Step-by-step explanation:
Since this is a parallelogram, it has two sets of equal sides. We are given that one of the sides is 19 and the perimeter is 72. Therefore, \
72 = 2*s + 2*19
72 = 2*s + 38
34 = 2*s
s = 17
Answer:
17
Step-by-step explanation:
19 + 19 = 38
38 divided by 2 = 17
Add the given length to itself again because the other side is equal.
Which would be 38. Divide by 2 since there are two missing lengths that need to be solved (s). And your final answer is 17!
Michael completely covered a square wall using 101.5ft2 of wallpaper without any overlap. Which measurement is closest to the side length of this wall in feet?

10.0747208398≈10
So, the side length is 10[tex]ft^{2}[/tex].
What is the solution for x In the inequality -3x+4<16
Answers
Answer:
x > -4
Step-by-step explanation:
-3x + 4 < 16
-3x < 16 - 4
-3x < 12
-x < 4
x > -4
Answer:
x > -4
Step-by-step explanation:
-3x+4<16
Subtract 4 from each side
-3x+4-4<16-4
-3x < 12
Divide each side by -3, remembering to flip the inequality since we are dividing by a negative.
-3x/-3 > 12/-3
x > -4

The perimeter of an equilateral triangle is 9 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. Find the side of the triangle.
Answers
Answer:
9 inches
Step-by-step explanation:

3x + 18 = 9 + 4x
-x = -9
x = 9
Solve (x - 3)^2+7=97, where X is a real number. Round your answer to the nearest hundredth.
Answers
Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ± [tex]\sqrt{90}[/tex] ( add 3 to both sides )
x = 3 ± [tex]\sqrt{90}[/tex]
Then
x = 3 - [tex]\sqrt{90}[/tex] ≈ - 6.49 ( to the nearest hundredth )
x = 3 + [tex]\sqrt{90}[/tex] ≈ 12.49 ( to the nearest hundredth )
