Answer: 16.7901
Step-by-step explanation: when dividing decimals, you need to make the divisor a whole number.
So, in this case you move the decimal point on 0.081 until it is a whole number.
then it would be 81 after moving the point 3 times to the right.
Now to make it even, you need to move the decimal point on 1.36: 3 times. You will then get: 1,360 divided by 81
And add back the decimal point once you divide.

Answer: [tex]y=-\frac{14}{5}[/tex]
Solving Linear Equations:
Simplify each side if necessaryIsolate the variable: use properties such as addition, subtraction, multiplication, or division to get the variable on one side and the rest terms to the other side of an equation.Solution with Steps:
[tex]14 =-5y[/tex]
[tex]\frac{14}{-5}=\frac{-5y}{-5}[/tex] - divide both sides by -5 to isolate for the variable

What is the value of x? Note:images are not to scale
since we know both triangles are similar then we can say that
[tex]\cfrac{TV}{QS}~~ = ~~\cfrac{TU}{QR}\implies \cfrac{x}{30}~~ = ~~\cfrac{13}{39}\implies 39x=390\implies x=\cfrac{390}{39}\implies \boxed{x=10}[/tex]
Solve. Check for extraneous solutions. 2(2 x)¹/₃ +1=5
x = 4 is not an extraneous solution.
Given equation [tex]2(2x)^{1/3}[/tex] + 1 = 5
Subtracting 1 on both the sides of the equation, we get
[tex]2(2x)^{1/3}[/tex] + 1 - 1 = 5 - 1
[tex]2(2x)^{1/3}[/tex] = 4
Dividing the equation by 2, we get
[tex]2(2x)^{1/3}[/tex] = 2
Taking cube of both the sides of the equation, we get
2x = 8
x = 4
Check for extraneous solution by keeping the value of x in original equation
[tex]2(2x)^{1/3}[/tex] + 1 = 5
[tex]2(2(4))^{1/3}[/tex] + 1 = 5
[tex]2(8)^{1/3}[/tex] + 1 = 5
2(2) + 1 = 5
5 = 5
LHS = RHS
Thus, x = 4 is not an extraneous solution.

For each function, find the inverse and the domain and range of the function and its inverse. Determine whether the inverse is a function. f(x)=1/(x+1)x²
Answer to this question is:
Domain of given function is (-∞,-1)∪(-1,0)∪(0,∞),{x|x≠0,-1}
Range of given function is (-∞,0)∪(0,∞),{y|y≠0}
Inverse of given function does not exist
The domain is all values of x that make the expression defined.The entire range of independent variable values is the domain of a function.
This definition can be stated simply as follows: The domain is the collection of all x-values that can be used to make the function "work" and produce actual y-values.
When choosing the domain, keep in mind that a fraction's denominator (bottom) cannot be 0.
Interval Notation:(-∞,-1)∪(-1,0)∪(0,∞)
Set-Builder Notation:{x|x≠0,-1}
The set of all valid y values constitutes the range..Graph may be used to find the values.
Interval Notation:(-∞,0)∪(0,∞)
Set-Builder Notation:{y|y≠0}
For calculation of inverse:
There is no inverse for any function that is not strictly monotonic. Whenever the first derivative of a function is ALWAYS zero, positive, or ALWAYS negative, the function is said to be monotonic. Basically, a function does not have an inverse function if there are two inputs for which the output is the same.
∴Domain of given function is (-∞,-1)∪(-1,0)∪(0,∞),{x|x≠0,-1}
Range of given function is (-∞,0)∪(0,∞),{y|y≠0}
Inverse of given function does not exist.

The measures of the angles are
TLN = 51 degrees, NLM = 129 degrees and MZQ = 129 degreesJZQ = TLN = 99 degreesLMO= ZMR = 34 degrees and LMR = y = 166 degreesHow to determine the measures of the angles?1. Angle TLN, MZQ and NLM
The angles TLN and NLM are supplementary angles
So, we have
TLN + NLM = 180
This gives
3x - 18 + y = 180
Also, we have
TLN + MZQ = 180
So, we have
3x - 18 + 5x + 14 = 180
Evaluate the like terms
8x -4 = 180
This gives
8x = 184
Divide
x = 23
Substitute x = 23 in 3x - 18 + y = 180
3 x 23 - 18 + y = 180
Evaluate
51 + y = 180
So, we have
y = 129
The above computations imply that:
TLN = 3 x 23- 18 = 51 degrees
NLM = y = 129 degrees
MZQ = 5 x 23 + 14 = 129 degrees
2. Angle JZQ and TLN
The above means that
JZQ = TLN
So, we have
9x + 9 = 8x + 19
Evaluate
x = 10
So, we have
JZQ = TLN = 9 * 10 + 9
JZQ = TLN = 99 degrees
3. Angle ZMR, LMO and LMR
The angles ZMR and LMO are congruent angles
So, we have
ZMR = LMO
This gives
x + 14 = 2x - 6
Evaluate
x = 20
Also, we have
LMR + LMO = 180
So, we have
y + 2x - 6 = 180
y + 2 x 10 - 6 = 180
y + 14 = 180
So, we have
y = 166
The above computations imply that:
LMO= ZMR = 20 + 14 = 34 degrees
LMR = y = 166 degrees

O Commutative Property of Addition
O Commutative Property of Multiplication
O Associative Property of Addition
O Associative Property of Multiplication
The algebra property used on -9.97 + (4.68 + 13.08)= (-9.97 + 4.68) + (13.08) is; Associative property of addition.
How to identify the Algebraic Property?
We are given the number expression;
-9.97 + (4.68 + 13.08) = (-9.97 + 4.68) + (13.08)
There are different algebraic properties such as Associative Property, Commutative Property, distributive property, e.t.c
Now, Associative property of addition states that changing the grouping of addends does not change the sum.
For example, (4 + 5) + 6 = 4 + (5 + 6)
Similarly; (7 + 8) + 9= 7 + (8 + 9)
Looking at our question, we see that the only thing that was changed is the grouping of addends and it did not change the sum. This, we conclude that algebra property used is Associative property of addition.

Work out the value of angle x
Answer:
166 degrees
Step-by-step explanation:
So first we need to find the angles in the triangle. One of the angles is 83 degrees since it's 180-97. Since the triangle is isosceles, the angle 'on top' of it is also 83 degrees. To find the last angle, you do 180-83-83, which is 14 degrees. To find x, you need to subtract 14 from 180, which is 166 degrees
Find the concentration of hydrogen ions in seawater, if the pH level of seawater is 8.5 .
The concentration of hydrogen ions in seawater is 3.126 × 10⁻⁶ mol / dm³.
The pH level of seawater is 8.5.
If the pH is 8.5, and If the pH is 8.5, Assuming that this is measured under normal circumstances, we can apply the following relationship:
pH + pOH = pK_(w)
At 25 degrees Celcius, pK_(w) = 14
Where K_(w) is the dissociation constant for water = 1.0 × 10⁻¹⁴,
(At 25° C) but pK_(w) is the negative logarithm of K_(w).
pK_(w) = − log₁₀[ K_(w) ]
From this, we can convert pH, the measure of H₃O⁺ ions, into pOH, the measure of OH⁻ ions in the seawater:
pH + pOH = 14
8.5 + pOH = 14
pOH = 14 - 8.5
pOH = 5.5
Now,
pOH = − log₁₀[ OH⁻ ]
10^{−pOH} = [ OH⁻ ]
So,
10⁻⁵·⁵ = [ OH⁻ ] ≈ 3.126 × 10⁻⁶ mol / dm³

What are polynomial functions ?In mathematics, polynomial function can be defined as the equation which consist of coefficient, variables and exponents. A polynomial equation has positive numbers as their exponent which is also known as its degree. All the equations such as monomials, quadratic equation, cubic equation, linear equation of one degree, two degree and more which has non negative number as their powers all are part of polynomial equation and can be taken as types of the polynomial equations.
Some examples of polynomial equation are :
2x+53x = 93x² + 5x+19(x-3)³According to question,
roots are √3 , -5
Thus the factors are :
