The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called corresponding angles. When the two lines are parallel, the corresponding angles are equal.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, the corresponding angles will be the same.
Since the first corresponding angle is 72°, the second angle x will be 72° as well. The correct answer is: x = 72° Option (D).
In the diagram below, AB is parallel to CD. What is the value of x?

X^3 + 7x^2 + 10x / x + 5
Answers
f(x) = x(x+5)(x+2) / (x+5)
f(x) = x(x+2)
The function is continuous everywhere/ in any domain.
The function x^3 + 7x^2 + 10x / (x + 5) is discontinuous at x = -5, where it has a jump discontinuity. The function is otherwise continuous and does not approach infinity, indicating no infinite discontinuity.
Explanation:The given function is x^3 + 7x^2 + 10x / (x + 5). To determine the continuity of the function, it's crucial to identify any values of x that would make the denominator zero since the function is undefined at these points.
In this case, if x is -5, the denominator will be zero, making the function undefined. Therefore, the function has a point of discontinuity or a jump discontinuity at x = -5.
The function does not have an infinite discontinuity because it never approaches infinity as x approaches any particular value. This function is continuous at every point except for x = -5. Therefore, "the function x^3 + 7x^2 + 10x / (x + 5) has one point of discontinuity at x = -5."

Tony invested $5,500 in a four-year CD that paid 4.8% interest, but later needed to withdraw $475 early. If the CD’s penalty for early withdrawal was three months’ worth of interest on the amount withdrawn, how much of a penalty did Tony pay?
a.
$5.70
b.
$22.80
c.
$60.30
d.
$66.00
Answers
Answer:
It's A-$5.70 :))))
Step-by-step explanation:
The penalty will be $5.70 which corresponds to option A.
The question is about calculating the penalty for early withdrawal from a Certificate of Deposit (CD). Tony invested $5,500 in a CD at a 4.8% interest rate and withdrew $475 early.
To calculate the penalty, we first need to find three months' worth of interest on the amount withdrawn.
The annual interest on $475 at 4.8% is:
Interest = Principal × Rate × Time
Interest = $475 × 0.048 × 1 = $22.80
Since the penalty is three months' worth, we divide the annual interest by 4 (because there are four 3-month periods in a year):
Penalty = $22.80 / 4
= $5.70

An equation that sets two fractions equal to each other is called a ____.
Answers
Final answer:
An equation that sets two fractions equal to each other is known as a proportion, where equivalent ratios or fractions indicate the same value. This maintains the equality governed by the rules of algebra, important when performing operations on both sides of an equation.
Explanation:
An equation that sets two fractions equal to each other is called a proportion. This type of equation indicates that two ratios or fractions are equivalent. For example, if we have ½ on one side of the equation and 2/4 on the other, we have a proportion because both fractions represent the same amount.
When we have fractions with the same value in the numerator and the denominator, such as ¹¹/₁₀⁰ for micrometers to meters, we can simplify this to 1 because the quantities cancel each other out. This is true by the rules of algebra, specifically the property that if we perform the same operation on both sides of an equality, the equation remains balanced. This concept is crucial when working with proportions and equations involving fractions.
It's also important to remember that when adding fractions, they must have a common denominator. Ratios and percentages are other forms of expressing relative sizes or amounts which can also be related back to fraction and proportion concepts.
A number t multiplied by -4 is a least -2/5
Answers
The inequality -4t ≥ -2/5, where t is the variable in question, simplifies to t ≤ 1/10, indicating that t must be less than or equal to 0.1. Negative time values are a conceptual tool used in physics to discuss intervals before a chosen start time.
The student's question is about solving an inequality involving a variable t and understanding the concept of negative time. The inequality is given as a number t multiplied by -4 is at least -2/5. Mathematically, this can be written as -4t ≥ -2/5. To solve for t, we can divide both sides by -4 (remembering that dividing by a negative switches the inequality sign), so t ≤ 1/10 or t is less than or equal to 0.1. This condition must hold true for any value of t for the statement to be correct.
The concept of negative time is often used in physics to describe events that occurred before a certain reference point in time. The references to negative time values represent periods before some initial event, similar to counting backward. A negative t value does not imply 'backward' time travel in the literal sense, but rather a point in time before the designated start (t = 0).

Explanation:
________________________________________
Given: 3x − 15 = 4x + 36 ; Solve for "x" .
________________________________________
Let us subtract: "3x" from EACH side of the equation; AND
add: "15 to EACH side of the equation:
__________________________________________
→ 3x − 15 − 3x + 15 = 4x + 36 − 3x + 15 ;
__________________________________________
to get:
__________________________________________
→ 0 = x + 51 ;
___________________________________
→ Subtract "51" from EACH side of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;
___________________________________
→ 0 − 51 = x + 51 − 51 ;
__________________________
→ - 51 = x ; ↔ x = - 51 ; which is: "Answer choice: [B]: -51".
___________________________________
→ Now, let us check our answer, "x = -51 ; by plugging in "-51" for "x" in the original equation, and seeing in both sides of the equation hold true when x = - 51 ;
______________________________
→ Given: 3x − 15 = 4x + 36 ;
→ Substitute "- 51 for "x" ;
→ Start with the "left-hand side" of the equation:
→ 3x − 15 = (3*-51) − 15 = -153 − 15 = -168 ; when x = -51 ;
→ Then, let us examine the "right-hand side" of the equation:
__________________________________________
→ 4x + 36 ; Substitute "-51" for "x" ;
→ (4*-51) + 36 = -204 + 36 = -168
→ Does the "left hand side" of equation = the "right-hand side of the equation" when: x = -51???
______________________________
→ That is, when x = -51, does: - 168 =? -168 ?? Yes!

What is corresponding angles?The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other and are equal in measure.
What is supplementary angles angles?When the sum of two angles is 180°, then the angles are known as supplementary angles. In other words, if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles.
According to the question
line a is parallel to line b and c and d are transversal for them
line c is parallel to line d and a and b are transversal for them
m∠13 = (12x - 22)°
m∠14 = (9x - 29)°
Now
As, ∠13 and ∠14 forms supplementary angles .
i.e
m∠13 + m∠14 = 180°
12x - 22° + 9x - 29° = 180°
21x - 51° = 180°
21x = 180° + 51 °
21x = 231 °
x = 11°
So,
m∠13 = 12*11 - 22° = 110°
m∠14 = 9*11 - 29° = 70°
Now,
according to corresponding angles
m∠14 = m∠6 = m∠2 = 70°
Hence, the measure of ∠2 is 70° .

Let f(x)=x^3-7x^2+25x-39 and let g be the inverse function of f. What is the value of g'(0)? ...?
Answers
Below are the choices that can be found from other sources:
a) -1/25
b) 1/25
c) 1/10
d) 10
e) 25
f(x) = x^3 - 7x^2 + 25x - 39
f'(x) = 3x^2 - 14x + 25
Since g is the inverse function of f
f(g(x)) = x
Differentiate both sides of equation
f'(g(x)) g'(x) = 1
Now f(3) = 0, so g(0) = 3
g'(x) = 1 / f'(g(x))
g'(0) = 1 / f'(g(0))
g'(0) = 1 / f'(3)
g'(0) = 1 / 10

Answers
Equations in point-slope form look like this: y - k = m(x - h) where m is the slope of the line and (h, k) is a point on the line (any point works). To write an equation in point-slope form, given a graph of that equation, first determine the slopeby picking two points.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
The form of a linear equation that shows the slope and one point is known as the point-slope form, which is written as y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope of the line.
The form of a linear equation that shows the slope and one point is known as the point-slope form. Unlike the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept, the point-slope form is typically written as y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope of the line.
For example, if you are given a slope of 3 and a point (2, 5), the equation of the line in point-slope form would be y - 5 = 3(x - 2). To visualize this, consider a line graph with the x-axis as the horizontal axis and the y-axis as the vertical axis.
If this was plotted, the line would rise 3 units on the vertical axis for every 1 unit it rises on the horizontal axis, illustrating the concept of slope as the rise over run, which is consistent along the entire length of a straight line.
