How do you solve for an area of a circle?
Answer:
Identify the radius of a circle. The radius is the length from the center of a circle to the edge of the circle. You can measure this in any direction and the radius will be the same. The radius is also one half of the diameter of a circle. The diameter is the line segment that passes through the center and connects opposite sides of the circle.[1]
The radius will generally be provided to you. It can be difficult to measure to the exact center of a circle, unless the center is already marked for you on a circle drawn on paper.
For this example, assume that you are told that the radius of a given circle is 6 cm.
well the formula for the area of a circle is A =[tex]\pi r^2[/tex]
r is for the radius
which is half the size or number of the diameter
so ex. lets say that the diameter of a circle is 10, so that makes the radius 5
A = [tex]\pi[/tex] [tex]5^2[/tex]
A = [tex]\pi * 25[/tex]
A = 78.54
Ta -Da!!
Note: sometimes is the test ask you to replace [tex]\pi[/tex] for 3.14, it would still work

is 144 a non real number yes or no
Answer:
No
Step-by-step explanation:
It is not a non-real number, as it it is a real number. Real numbers are any numbers that can exist, and the only imaginary(non-real) numbers are the square roots of negative numbers.
In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc
Answer:
[tex]\angle BDC=80^{\circ}[/tex]
Step-by-step explanation:
We are given that
[tex]\angle ABC=69^{\circ}[/tex]
[tex]\angle ACB=31^{\circ}[/tex]
We have to find the angle BDC.
In triangle ABC
Sum of interior angles of triangle=180 degrees
[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]
[tex]69+31+\angle BAC=180[/tex]
[tex]100+\angle BAC=180[/tex]
[tex]\angle BAC=180-100[/tex]
[tex]\angle BAC=80^{\circ}[/tex]
[tex]\angle BAC=\angle BDC=80{\circ}[/tex]
Angles subtended on the same are ac are equal.
[tex]\angle BDC=80^{\circ}[/tex]

Use vertex (h, k) and a table of values g(x) = 2 * (x - 2) ^ 2 + 5
Step-by-step explanation:
Since the equation is in vertex form: a(x - h)² + k, we immediately know that the vertex is at (2, 5).
x | y
0 | 13
1 | 7
2 | 5
3 | 7
4 | 13
Answer:
Step-by-step explanation:
Comparing the given g(x) = 2(x - 2) ^ 2 + 5 to h(x) = a(x - h)^2 + k, we see that h = 2, k = 5, a = 2. Thus, the vertex is at (2,5). Several sample points on this graph are:
x y = g(x) (x, y)
2 5 (2, 5)
0 2(0-2)^2)+ 5 (0, 13)
1 2(1-2)^2 + 5 (1, 7)
3 2(3-2)^2 + 5 (3, 7)
and so on. Plot these are several more points and then draw a smooth curve through them. The graph will be a parabola with vertex (2, 5) that opens up.

x2 − 6x + 5 = 0
Step 1: Write the related function.
x2 − 6x + 5 = 0
y = x2 − 6x + 5
Step 2: Graph the function.
Use a graphing calculator.
Step 3: Find the zeros.

a) Si el área de uno de los rectángulos
es de 156 cm2, ¿Cuáles son sus
dimensiones?
Answer:
El problema parece incompleto, asi que lo respondere en una forma general.
Sabemos que para un rectángulo de largo L y ancho W, el área se calcula como:
A = L*W
En este caso, sabemos que el área del rectángulo es:
A = 156cm^2
Entonces tenemos:
156cm^2 = L*W
No tenemos más información del rectángulo, entonces solo podemos llegar a algo como:
L = (156cm^2)/W
Que nos habla de la relación entre el largo y el ancho del rectángulo.
Write an expression that is the product of two factors and is equivalent to - 2x - 16.
Which expression is the product of two factors and is equivalent to - 2x - 16?
O A. -2x-1-15
OB. -2(x-8)
OC. (8x - 1)-(10x-15)
OD -2(X + 8)
Answer:
D
Step-by-step explanation:
Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.
Answer B does not work, as when it is multiplied out, we get -2x + 16.
When we find the product of D, we distribute the negative and get the correct product, -2x - 16
Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?
2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answer:
it may be B but I think it's C
Step-by-step explanation:
not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides
Both triangles are congruent by (SAS) side-angle-side postulate.
The correct option is B.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.
Given,
Two triangles
ABC and DEC
AB = DE (Given)
BC = EC (Given)
∠ACB = ∠DCE (Vertical angles at intersection of DB and AE)
By, Side-Angle-side theorem of congruent triangles,
ΔABC ≅ΔDEC
Hence, by side-angle-side (SAS) postulate, both triangles are congruent.

Answer:
x=5/3 your answer right answer
Answer:
110
Step-by-step explanation:
The expansion (a + b)³ is
(a + b)³ = a³ + b³ + 3ab(a + b)
Then
(x + [tex]\frac{1}{x}[/tex] )³ with a = x and b = [tex]\frac{1}{x}[/tex]
= x³ + [tex]\frac{1}{x^3}[/tex] + 3x . [tex]\frac{1}{x}[/tex] (x + [tex]\frac{1}{x}[/tex] )
Thus
x³ + [tex]\frac{1}{x^3}[/tex] = (x + [tex]\frac{1}{x}[/tex] )³ - 3(x + [tex]\frac{1}{x}[/tex] )
= 5³ - 3(5)
= 125 - 15
= 110
