In the figure below, C is between A and D, and B is the midpoint of AC. If BC=3 and AD=13, find CD.
The length of CD is 7 units.
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
From the figure it is given that C is between A and D.
B is the midpoint of AC
BC=3 and AD=13, we have to find CD.
As B is the midpoint of AC, then BC=AB
BC=AB=3
AC=AB+BC=6
Now to find CD=AD-AC
CD=13-6
CD=7
Hence, the length of CD is 7 units.

Naomi earned $45 after babysitting for 5 hours one afternoon. Another day, she babysat for
8 hours and earned $72. Write two equations (one in point-slope and one in slope-intercept)
that represents the number of hours she babysits, x, and the amount of money she earns, y.
Leticia babysat 5 hours on Saturday.
How to calculate?First, we have to look at the equation that models this situation. We learn that the price per hour of babysitting is $8. On Friday, Leticia babysat for 4 hours, and on Saturday, she babysat an unknown amount of time. Leticia watched the children for four hours on Friday and for an undetermined period of time on Saturday.
earned $72, Therefore:
8 ( 4 + x ) = 72
( 4 + x ) = 72 / 8
4 + x = 9
x = 9 - 4
x = 5

The base of a right triangle is 48cm and its hypotenuse is 50cm. What will be the areas of the triangle? class 9
The area of a triangle can be found using the formula:
Area = (1/2) * base * height
In this case, the base of the triangle is 48cm and the hypotenuse is 50cm. Since this is a right triangle, we can use the Pythagorean theorem to find the length of the height. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. So,
c^2 = a^2 + b^2
50^2 = 48^2 + b^2
2500 = 2304 + b^2
b^2 = 2500 - 2304
b = √(2500 - 2304)
b = √(196)
b = 14
So, the height of the triangle is 14cm.
Area = (1/2) * 48 * 14 = 336cm^2
Factorise a³ + b³ + c³ please i need this immediately
Answer:
a³(b-c) + b³(c-a) + c³(a-b) = (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)
This is a factorized form of the polynomial, as you can see it factorizes as a combination of difference of squares and difference of cubes.
here is one way to factorize the polynomial a³(b-c) + b³(c-a) + c³(a-b) step by step:
First, we can factor out a³ from the first term, b³ from the second term, and c³ from the third term:
a³(b-c) + b³(c-a) + c³(a-b) = a³(b-c) + b³(c-a) + c³(a-b)
Next, we can factor out (b-c) from the first and second terms, and (c-a) from the second and third terms:
a³(b-c) + b³(c-a) + c³(a-b) = (b-c)(a³ + b³) + (c-a)(b³ + c³)
We can factor out (a-b) from the first and third terms, and then we can use difference of cubes to factorise out:
(b-c)(a³ + b³) + (c-a)(b³ + c³) = (b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²)
Now we can combine like terms, and we get:
(b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²) = (a-b)(b-c)(c-a)(a + b + c)(a² + b² + c² - ab - bc - ca)
The factorized form of the polynomial is (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)
This is a general formula for the factorization of a polynomial of the form a³(b-c) + b³(c-a) + c³(a-b)
By using difference of cubes we can factorise the above polynomial, hope it helps.

What is the ratio of the 3 sides of a 45 − 45 − 90 triangle?.
The ratios of the sides of a 45-45-90 triangle are 1:1:[tex]\sqrt{2}[/tex].
A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.
In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.

The point of intersection of the perpendicular bisectors of the sides of a triangle is called circumcenter
What are perpendicular bisectors?Lines that cut through the middle of each side of a triangle's perpendicular bisector are perpendicular to the provided side. The circumcenter (Durell 1928), which is also the center of the triangle's circumcircle, is where the triangle's three perpendicular bisectors (Casey 1888, p. 9) meet.Measuring a line segment that needs to be bisected will help you discover a perpendicular bisector. The midway of the measured length can then be determined by dividing it by two. From this center, extend a line at a 90-degree angle.The circumcenter is where the perpendicular bisectors of a triangle's sides meet. It is located in the middle of a triangle's perimeter. The center of a polygon's circle is known as the circumcenter. The polygon's circumcenter, also known as the center of that circle, is the circle that passes through all of the polygon's vertices.

The value of tan A is 5/12.
To find the value of tan A, we use the trigonometric function tangent, which is defined as the ratio of the length of the side opposite angle A to the length of the side adjacent to angle A. In a right triangle, these sides are labeled as x and y, respectively. Therefore, to find the value of tan A, we divide the length of the side opposite angle A (x) by the length of the side adjacent angle A (y).

What is the inverse of an exponential function?.
The inverse of an exponential function is the natural logarithm function. More specifically, if f(x) = a^x, where a is a positive constant and x is a real number, then the inverse function, denoted as f^-1(x), is given by f^-1(x) = log_a(x).
An inverse function is a function that "undoes" the effect of another function. In other words, if we have two functions, f and g, such that g(f(x)) = x for all x in the domain of f, and f(g(x)) = x for all x in the domain of g, then f and g are inverses of each other.
In the case of exponential functions, f(x) = a^x where a is a positive constant and x is a real number, the inverse function is the natural logarithm function, g(x) = log_a(x).
The natural logarithm function "undoes" the effect of the exponential function by taking the logarithm of the output of the exponential function with base 'a' and returns the input value.

Make a the subject of the formula:
4b(5a-2) =2c
Step-by-step explanation:
Firstly you have to open brackets
4b(5a - 2) = 2c
20ab - 8b = 2c
20ab = 2c + 8b
Divide both sides by 20b(coefficient of a)
a = (2c + 8b)/20b
Answer:
[tex]a = \dfrac{2}{5} + \dfrac{c}{10b}[/tex]
Step-by-step explanation:
Expand 4b(5a-2) on the left side
4b(5a-2) = 4b · 5a -4b · (-2)
= 20ab -8b
Therefore we get
20ab -8b = 2c
Add 8b on both sides to get rid of the -8b on the left
20ab - 8b + 8b = 2c + 8b
20ab = 8b + 2c
Divide by 20 both sides:
20ab/20 = 8b/20 + 2c/20
ab = (2/5)b + c/10
Divide by b both sides
==> ab/b = (2/5)b/b + c/10b
==> a = 2/5 + c/10b

f(x) = 4x/11 + 1 ==> y = f(x)
f(5) = 4(5)/11 + 1 ==> substitute 5 for x
f(5) = 20/11 + 1 ==> simplify
f(5) = 20/11 + 11/11 ==> make common denominators to simplify easier
f(5) = (20+11)/11
f(5) = 31/11

4. You are standing at point B. Point B is 21 feet from the center of the circular water storage tank and 19 feet from point A. AB is tangent to ⊙O at A. Find the radius of the tank. (Round answer to one decimal place)
The radius of the tank is 28.3 feet (rounded to one decimal place).
What is radius?Radius is a term used to describe the distance from the center of a circle to any point on the circumference. It is a line segment that runs from the center of the circle outwards, perpendicular to the circumference. The radius of a circle is the same for all points on the circumference, and it is always half of the diameter.
The radius of the tank can be determined using the Pythagorean Theorem. Since we are given the distances from the center of the tank (O) to points A and B, we can use the following formula to calculate the radius:
R = √(OA² + OB²).
Plugging in the given values, we get:
R = √(21² + 19²) = √(441 + 361) = √802 = 28.29
Therefore, the radius of the tank is 28.3 feet (rounded to one decimal place).
