Triangle UML has coordinates U (-3, -4), M(-1, -1) , and L(-2, -5). If the triangle is translated 5 units up and 1 unit left to form triangle U’M’L’, what will be the coordinates of L’?
After the translation the coordinates of L' are (-3, 0) for the new triangle of U’M’L’.
What is defined as the translation?In geometry, translation refers to a function which moves an object a specified distance. The object is not elsewhere altered. It is not rotated, mirrored, or resized.Every location of the object should be moved within the same direction for the same distance during a translation.When performing a translation, this same initial object is referred to as the pre-image, and also the object just after translation is referred to as the image.The coordinates of triangle are-
U (-3, -4), M(-1, -1) , and L(-2, -5).
The triangle is translated 5 units up and 1 unit left to its original place.
Thus, for the 5 units up translation 5 units will get added to the y-coordinates.
New y-coordinate of L' is -5 + 5 = 0.
For 1 unit left , 1 units will get reduced from the original x-coordinate.
New x-coordinate = -2 - 1 = -3
Thus, the new coordinates L' becomes (-3, 0).

a = h/b, solve the formula for b
a = h/b
x b, both sides
ab = h
÷a
b = h/a
B = h/a
Hope this helps!
Answer: b = h/a
Step-by-step explanation: What you need to do is to get b by itself and to do that you have to move b to the other side because it's being divided by b. To do that you multiply by b on both sides.
1) ab = h
Now, isolate b by dividing a into both sides.
2) b = h/a
Now, you have b alone you know what b is equal to.

Total number of possible equal parts in a fraction (a) denominator (b) numerator (c) mixed number (d) divisor?
Denominator: The value in a fraction that appears below the fractional bar and indicates the total number of equal parts.
In a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the vinculum.
A mixed number is a representation of both a whole number and a legal fraction. In most cases, it denotes a number that falls between any two whole numbers.
An integer that totally or partially divides another integer is known as a divisor.
In a division equation, a divisor is represented by the formula

angle A and angle B are vertical angles. If m angle A=(2x+20)^ and m angle B=(3x+1)^ then find the value of x.
If angle A and angle B are vertical angles. If m angle A=(2x+20)^ and m angle B=(3x+1)^ then x has a value of 19.
What is the Vertical Angles Theorem?
The Vertical Angles Theorem states that if two lines intersect, then the vertical angles formed by the intersecting lines are congruent.
Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. Vertical angles are always congruent angles,
By the Vertical Angles Theorem, we know that angle A is congruent to angle B.
Therefore, we can set their angle measures equal to each other and solve for x:
2x + 20 = 3x + 1
Subtract 2x from both sides:
20 = x + 1
Subtract 1 from both sides:
19 = x
Hence, x has a value of 19.

What is the measure of the missing angle of the a right triangle?
A right triangle is a triangle, of which one of the three angles is a right angle. In accordance with Euclidean geometry, the sum of the measures of the internal angle is equal to 180°. Then,
m ∠ A + m ∠ B + m ∠ C = 180°
90° + 34° + m ∠ B = 180°
124° + m ∠ B = 180°
m ∠ B = 180° - 124°
m ∠ B = 56°
The measure of the angle B is equal to 56°.

Answer:
2x + 2 + h.
Step-by-step explanation:
F(x+h) is f(x) where x+h replaces x:-
f(x + h) = (x + h)^2 + 2(x + h) - 3
[f(x+h) - f(x)] / h
= (x + h)^2 + 2(x + h) - 3 - (x^2 + 2x - 3) / h
= [x^2 + 2hx + h^2 + 2x + 2h - 3 - x^2 - 2x + 3] / h
= (2hx + h^2 + 2h) / h
= 2x + 2 + h
The limit of [f(x+h) - f(x)] / h as h ----> 0 is 2x + 2.
We refer to 2x + 2 as the derivative of x^2 + 2x - 3.
In what situation would a geometric model be better than a binomial model
Binomial distribution describes the variety of successes k accomplished in n trials, wherein opportunity of achievement is p. Geometric distribution is a unique case of bad binomial distribution, wherein the test is stopped in the beginning failure (r = 1).
The not common definition of the Geometric distribution is the variety of trials till the primary achievement.. The following is an instance for the distinction among the Binomial and Geometric distributions: If a own circle of relatives comes to a decision to have five youngsters, then the variety of girls (successes) within side the own circle of relatives has a binomial distribution. If the own circle of relatives comes to a decision to have youngsters till they have got the primary lady after which stop, the the variety of youngsters within side the own circle of relatives has a Geometric distribution . A variant at the Geometric distribution is counting the variety of failures till the primary achievement, after which the variety may be 0,1,2,... In the instance it might be counting the variety of boys within side the own circle of relatives earlier than the primary lady turned into born, and now no longer the entire variety of youngsters. The distinction among the 2 versions is usually 1.

A 5-foot board is cut into 4 equal pieces. Which equation shows how to find the length of each piece?
Solve the equation x+ 4x-7 = 0 by completing the square. give your answers correct to 2 decimal places.
[tex] {x}^{2} + 4x - 7 = 0 \\ → {x}^{2} + 4x = 7[/tex]
Add the square of the half of the coefficient of the unknown(x) to both sides of the equation.
[tex] {x}^{2} + 4x + ( \frac{4}{2} {)}^{2} = 7 + ( \frac{4}{2} {)}^{2}[/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + (2 {)}^{2} [/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + 4[/tex]
Bring out x and 2 and square them as shown below:
[tex](x + 2 {)}^{2} = 11[/tex]
Now, square root both sides of the equation to find the value of x as shown below:
[tex] \sqrt{(x + 2 {)}^{2} } = \sqrt{11} [/tex]
Add a + or - sign since it is a quadratic equation
[tex]x + 2 = \binom{ + }{ - } \sqrt{11} [/tex]
[tex]x + 2 = \binom{ + }{ - } 3.3166[/tex]
[tex]x = - 2 + 3.166 [/tex] or

ridden a bike course that is 40 miles long. so far he has ridden 28 miles of the course. what percentage of the course has he ridden so far
So far, he has ridden 70% of the bike course.
Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".
The formula to get the percentage is:
Percentage = (Value / Total Value) × 100
If the total value of the bike course is 40 miles and the value which the percentage we are looking for is 28 miles, evaluating the equation:
Percentage = (Value / Total Value) × 100
Percentage = (28 / 40) × 100
Percentage = (0.7) × 100
Percentage = 70
Therefore, he has ridden 70% of the bike course so far.
