Answer:
To approximate the square root of 46 to the tenths place, we need to find the two-digit number that is closest to the square root of 46. Since the square root of 46 is between 6 and 7, we can estimate that it is about 6.5. We can check this estimate by finding the square of 6.5, which is 42.25. This is close to 46, but it is still a little bit lower than 46, so we can estimate that the square root of 46 is slightly larger than 6.5. Therefore, an approximation of the square root of 46 to the tenths place is 6.6.

write an equation in point-slope form for the line that passes through (2,-5) and is perpendicular to the graph of y=3x+1
An equation in point-slope form for the line that passes through (2,-5) and is perpendicular to the graph of y=3x+1 is y = -1/3x-17/3.
What is a slope-intercept form?When the line to be examined slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilized (0, b). B stands in for the y value of the y-intercept point in the formula. In order to make it simple to identify the slope and y-intercept of a line, its equation can be written in the slope-intercept form. The y-intercept, or point where the line crosses the y-axis, is referred to as the slope.
Perpendicular line slopes are reciprocals with a negative sign. In the slope-intercept form, y = mx + b, where m is the slope, the supplied line, y = 3x+1, is already in the slope-intercept form.
The line in the example has a slope of 3.
The negative reciprocal of three, or -1/3, is the slope of the perpendicular.
Y = -1/3x + b is the equation for the line that we are looking for.
We must track down b. We solve for b by using the x and y coordinates of the provided location as x and y in the equation above.
y = -1/3x + b
5 = (1/3)(2) + b
5 = (2/3) + b
b = -5-(2/3)
b= -17/3
B is now substituted for in the equation
y = -1/3x-17/3 as we know that b =-17/3.
Therefore, an equation in point-slope form for the line that passes through (2,-5) and is perpendicular to the graph of y=3x+1 is y = -1/3x-17/3.

Triangle DEF is a scaled copy of Triangle ABC}, answer the following question equations that could be used to solve for x.
7 ÷ x = 1.5 is the equation used to solve for x.
Given,
Triangle DEF is a scaled copy of triangle ABC.
We have to find the equation to solve for x.
Scaled Copy;-
A scaled copy is a representation of a figure in which each length from the original representation has been multiplied by the same amount. Triangle ABC, for instance, is a scaled version of triangle DEF. Triangle DEF's side lengths were calculated by multiplying each side length from triangle ABC by 1.5.
Here,
Length of side AB = 6
Length of side DE = 4
Let y be the value used for scaling.
Then,
6 = 4y
y = 6/4 = 1.5
So,
Length of side BC ÷ x = 1.5
7 ÷ x = 1.5
7 = 1.5x
x = 7/1.5
x = 4.67

Given the following table of values of the polynomial f(x), what is the minimum number of zeros of f(x) that are guaranteed to exist by the Intermediate Value Theorem?
The number of zeros of f(x) that are guaranteed to exist by the Intermediate Value Theorem is given as follows:
0.
What is the Intermediate Value Theorem?The intermediate value theorem defines that if a continuous function passes in two points, it will pass through all the points between these two values.
The zeros of a function are all the values of x for which the function assumes a value of zero.
Hence, if for a value of x = a the function is positive, and then for a value of x = b > a the function is negative, or vice versa, a zero is guaranteed to exist in the interval between a and b.
In this problem, the function does not assume any negative values, hence a zero is not guaranteed to exist in the function, and the number is of zero.

Write an equation of a line with the given slope and y-intercept.
m = 1, b = 4
Answer: " y = x + 4 ".
Step-by-step explanation:
We shall write the equation of a line written in slope-intercept format;
that is, " y = mx + b " ;
in which y is isolated as a single variable on the 'left-hand' side of the question, and with no "coefficient"—
{except for the implied coefficient of 1 }; and:
m refers to the slope of the line—and is the coeffcient of x ;
and b refers to the y-intercept—or more specifically, the value of the y-coordinate when "x = 0" [i.e. the value of the y-coordinate where the line crosses the x-axis].
So: We can plug the given values: m = 1 ; and b = 4 ; into the equation:
" y = mx + b " ; as follows:
→ y = 1x + 4 ; Note: By convention, we often omit the 1 as the coefficient of x —since the 'stand-alone' variable, x ; has an implied coefficent of x ; and we can write the equation:
→ y = x + 4 ; which is our answer.|

hi everyone, I'm studying for a math test. I just have one specific question: are all equations in the format y=mx+b linear equations? Or do I still need to graph it and check if it is a straight line first??
Yes, all equations in the format y=mx+b are linear equations. In this format, "m" represents the slope of the line and "b" represents the y-intercept, which is the point where the line intersects the y-axis. This means that all equations in this format will produce a straight line when graphed.
However, it is always good practice to graph the equation to confirm that it is a straight line. This will also allow you to see the slope and y-intercept of the line, and check if they match the values of "m" and "b" in the equation.

What is Fraction?
A fraction is a mathematical expression that represents the division of a whole number or quantity into parts. It is written as two separate numbers, a numerator and a denominator, separated by a slash. The numerator represents the number of parts being considered, and the denominator represents the total number of parts. Additionally, fractions can also represent parts of a whole number. For example, the fraction 1/2 represents one part of a whole number that has been divided into two equal parts. Fractions can also be combined to create a sum of parts.

f(x) → −∞, as x → −∞
f(x) → −∞, as x → +∞
The degree of the function is even, and the leading coefficient is negative.
End behaviour of a function:
A polynomial function's final behaviour is how its graph behaves as x gets closer to positive or negative infinity.
The graph's final behaviour is determined by a polynomial function's degree and leading coefficient.
For very big or very small values, the leading coefficient is more important than the other function coefficients. Therefore, it is sufficient to forecast the function's final behaviour based on the sign of the leading coefficient.
To predict the end-behaviour of a polynomial function, first check whether the function is odd-degree or even-degree function and whether the leading coefficient is positive or negative.

Frank is wanting to create a scale model of the Eiffel Tower. The real Eiffel Tower is 984 feet tall and 328 feet wide at its base. If Frank's model is 12 inches tall, how wide (in inches) must his scale model be?
Answer:
4 Inches.
Step-by-step explanation:
To find the width of Frank's scale model, we need to first determine the scale of the model. This can be done by dividing the height of the real Eiffel Tower by the height of Frank's model. Since the real Eiffel Tower is 984 feet tall and Frank's model is 12 inches tall, the scale of the model is 984 / 12 = 82 feet per inch.
Next, we can use this scale to determine the width of the model. Since the real Eiffel Tower is 328 feet wide at its base, and the scale of the model is 82 feet per inch, the width of the model must be 328 / 82 = 4 inches.
Therefore, the width of Frank's scale model of the Eiffel Tower must be 4 inches.
