When the product of a number m and 1.7 is 6.63 the required value of m is 3.9

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given statement is,

The product of a number m and 1.7 is 6.63

Thus, converting it into numerical form we get,

1.7m = 6.63

Dividing both the side by 1.7 we get,

1.7m/1.7 = 6.63/1.7

Solving we get,

m = 3.9

this is the required value of m.

Thus, when the product of a number m and 1.7 is 6.63 the required value of m is 3.9

Based on the expression the number of grid squares in a character of size 7 is 55

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression for the number of grid squares in a character of size s is given as

6 + s^2

Rewrite the expression as a function

So, we have

f(s) = 6 + s^2

To find the number of grid squares in a character of size 7, we set s to 7

i.e. s = 7

So, we have

f(7) = 6 + 7^2

Evaluate the exponent

So, we have

f(7) = 6 + 49

Evaluate the sum

So, we have

f(7) = 55

Hence, the number of grid squares in a character of size 7 is 55

Given that you are in the 88th percentile for GPA, there are 72 students that have a GPA greater than or equal to yours.

Percentile refers to the measure used to indicate the value below which a certain percentage of data lies.

If a data is said to be in the nth percentile, this means that n% of the data in the distribution are equal to or lower than that data.

If you are in the 88th percentile, then 88% of all the 600 students have a GPA equal or lower than yours.

88% of 600 = 0.88(600) = 528

students that have a GPA greater than or equal to yours = 600 - 528

The equation of the line that passes through (2, -6) and is perpendicular to the given line is y = -x -4

From the question, we are to determine the equation of a line that passes through (2, -6) and it perpendicular to y = x + 4

If two lines are perpendicular, the product of their slope is -1.

That is,

m₁m₂ = -1

First,

We will determine the slope of the line that the equation was given

y = x + 4

Comparing with the slope-intercept form of the equation of a straight line

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison

m = 1

The slope of the line that the equation was given is 1

Thus,

The slope of the line that is perpendicular to this line is -1

From the given information,

The line passes through the point (2, -6)

Using the point-slope form of the equation of a line

y - y₁ = m(x - x₁)

Then,

y - -6 = -1(x - 2)

y + 6 = -x + 2

y = -x + 2 - 6

y= -x -4

Hence, the equation of the described line is y = -x -4

The inverse function returns the original value for which the output of a function was given.

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2 be the inverse the function y = (1 - 2x)² + 5.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value. The inverse of f is then g(y) = (y - 5)/2 = x.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Let the equation be y = (1 - 2x)² + 5

simplifying the above equation, we get

√(x - 5) y = (1 - 2x)² + 5

x = (1 - 2y)² + 5

The function of x be x = (1 - 2y)² + 5

x - 5 = (1 - 2x)²

± √(x - 5) = (1 - 2y)

± √(x - 5) - 1 = 2y

Divide both sides of the equation by 2, we get

[± √(x - 5) - 1]/2 = 2y/2

[± √(x - 5) -1] /2 = y

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2
