The measure of ∠V of the parallelogram is = 150.5°
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the measure of the angle ∠Y = 10x + 27
Let the measure of the angle ∠W = 2x + 29
Now , for a parallelogram the opposite sides are congruent and opposite angles are congruent

Subtracting 2x on both sides of the equation , we get
8x + 27 = 29
Subtracting 27 on both sides of the equation , we get
8x = 2
Divide by 8 on both sides of the equation , we get
x = 1/4
Let the measure of the angle ∠Y = 10 ( 1/4 ) + 27
Let the measure of the angle ∠Y = 2.5 + 27
Let the measure of the angle ∠Y = 29.5°
Now , same-side interior angles (consecutive angles) are supplementary
Substituting the values in the equation , we get
angle ∠Y + angle ∠V = 180°
29.5° + m∠V = 180°
Subtracting 29.5 on both sides of the equation , we get
m∠V = 150.5°
Hence , the measure of m∠V = 150.5°

Answer:
The required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.
Step-by-step explanation:
Given that,
An oven is turned on and set to reach the desired temperature of 350 degrees Fahrenheit. The oven warms up at a constant rate. The oven’s temperature is 134 degrees Fahrenheit at 1 minute and it reaches its desired temperature at 5 minutes.
What are functions?
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
At time m = 1 min, temperature T = 134 °F
At time m = 5 min. temperature T = 450 °F
Slope of the equation M = 450 - 134 / 5 - 1
= 216 / 4
= 54
Linat relationship can be given as,
T - 134 = 54 (m - 1)
T = 54m -54 + 134
T = 54m + 80
Thus, the required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.

Is molar mass equal to Avogadro's number?.
Yes, The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10²³(Avogadro's number) atoms, molecules, or formula units of that substance.
The Avogadro constant, A, is the number of particles (such as atoms, molecules, or ions) in one mole of something. Its value is modernly defined as exactly 6.022 140 76 × 10²³. (As it is a pure number, it has no units.)
So, in 1 mol of helium, which has a mass of (very close to) 4 g, there are A
atoms; in 1 mol of sucrose, with a mass of 342 g, there are A molecules.

if f(x) = x^3 -12x^2 + 29x + 42 and f(7) = 0, then find all zeros of f(x) algebraically
The zeroes of the polynomial f(x) are 7, 6 and -1. The solution is obtained by the method of polynomial long division.
What is polynomial long division?
A long division polynomial is a formula for dividing one polynomial by another of the same degree or lower. The divisor, quotient, dividend, and remainder are all components of the long division of polynomials, just like they are for long division of numbers.
We are given f(7) = 0.
This means that (x-7) is one factor of f(x).
Using Polynomial Long Division,
Dividing : x^3 -12x^2 + 29x + 42 ("Dividend")
By : x-7 ("Divisor")
Dividend x^3 - 12x^2 + 29x + 42
- divisor * x2 x^3 - 7x^2
Remainder - 5x^2 + 29x + 42
- divisor * 5x - 5x^2 + 35x
Remainder - 6x + 42
- divisor * (-6) - 6x + 42
Remainder 0
Quotient : x^2-5x-6
Remainder: 0
Now, factoring x^2-5x-6 , we get
⇒x^2-6x+x-6
⇒x(x-6)+1(x-6)
⇒(x+1)(x-6)
Thus, the factors are (x+1), (x-6) and (x-7).

What is the differentiation of log 7 x?.
The derivative of log₇(x) is 1/(xln(7))
To find the derivative of log₇(x), we can use the chain rule and the properties of logarithms.
The chain rule states that if we have a composite function, such as y = f(g(x)), then the derivative of y with respect to x is given by
dy/dx = dy/dg * dg/dx.
In this case, y = log_7(x) and g(x) = x, so
dy/dx = d/dx (log_7(x))
As by logarithmic property log₇x = ln(x)/ ln(7)
dy/dx = d/dx (ln(x)/ln(7))
To find the derivative of ln(x), we can use the property that the derivative of ln(x) is 1/x. This is because the natural logarithm function is the inverse of the exponential function eˣ, and the derivative of eˣ is eˣ. Therefore, the derivative of ln(x) is the reciprocal of x, or 1/x.
The differentiation of log₇(x) is given by:
d/dx (log₇(x)) = (1/x) * (d/dx (x)) * (1/ln(7))
= (1/x) * 1 * (1/ln(7))

Erika is 12 years older than her friend Nick. She is also 3 times as old as Nick. Let x represent Nick’s current age.
Answer:
Nick is 6 years old.
Erica is 18 years old.
Step-by-step explanation:
Hello!
We know that Erica is 12 years older than Nick, which also means she is 3 times older than Nick. We can represent this situation as two equations.
Let E be Erica's age, and x be Nick's age.
E = x + 12, and E = x* 3
Since E is equal to E, we can say that x + 12 = 3x.
Solve for xx + 12 = 3x12 = 2x6 = xThe value of x is 6. Nick is 6 years old, and Erica is 18 years old.

Find The coordinate of the interection of the diagonal of a parallelogram with the vertical WXYZ
The coordinate of the intersection is (k, m*k + b).
A parallelogram is a four-sided shape with opposite sides that are parallel. The diagonal of a parallelogram cuts the shape into two congruent triangles. The coordinates of the intersection of the diagonal of a parallelogram with the vertical line of the parallelogram can be found by solving the equation of the line that forms the diagonal and the equation of the vertical line.
If the diagonal of the parallelogram is given by the equation y = mx + b, where m is the slope of the diagonal and b is the y-intercept, and the vertical line is given by the equation x = k, where k is the x-coordinate of the vertical line.
To find the x-coordinate of the intersection point, we can substitute x = k into the equation of the diagonal:
x = k
Then, we can substitute this value of x into the equation of the diagonal:
y = mx + b
This will give us the y-coordinate of the intersection point.
So, the coordinate of the intersection is (k, m*k + b)
Note: You need the equation of the diagonal and the equation of the vertical line to find the intersection point.
Therefore, The coordinate of the intersection is (k, m*k + b).

Given f(x)=4(2)^x
a. find f(4)
b. write your answer as a logarithmic expression
a) The numeric value at x = 4 is given as follows: f(4) = 64.
b) The logarithmic expression is given as follows: x = log2(16).
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
f(x) = 4(2)^x.
At x = 4, the numeric value is found replacing the lone instance of x by 4, hence:
f(4) = 4(2)^4 = 64.
For the logarithmic expression, we obtain the inverse function, hence:
64 = 4(2)^x.
2^x = 16
x = log2(16).

What is logarithm?A logarithm is a mathematical function for expressing the relationship between two integers. It is the exponent to which a base number must be increased in order to equal a particular number. The base-10 logarithm of 100, for example, is 2, because 10 to the power of 2 equals 100.
Let y = [tex]4^{x}[/tex]
[tex]16^{x}[/tex] + 64 = 5y - 1
[tex]16^{x}[/tex] = 5y - 65
Dividing both sides by 16
x = (5y - 65)/16
x = (5*[tex]4^{x}[/tex] - 65)/16
Substituting y = [tex]4^{x}[/tex]
x = (5*([tex]4^{x}[/tex]) - 65)/16
Simplifying,
x = (5*[tex]4^{x}[/tex] - 65)/16
x = (20*[tex]4^{x}[/tex] - 260)/16
Divide both sides by 20
x = ([tex]4^{x}[/tex] - 13)/2
Take the logarithm of both sides:
log(x) = log([tex]4^{x}[/tex] - 13)/2
Apply the laws of logarithms:
log(x) = x*log(4) - log(13)/2
Solve for x:
x = (log(13)/2)/log(4) - log(x)/log(4)
x = (log(13)/2 - log(x))/log(4)
