Answer:
Step-by-step explanation:
Area of figure I = length * width
= 8 *16
= 128 cm²
Area of figure II = length * width
= 4 * 3
= 12 cm²
Trianlge:
base = b = 7 cm
height = 4 + 4 + 6 = 14 cm
[tex]\text{area of triangle =$\dfrac{1}{2}*b*h$}[/tex]
[tex]= \dfrac{1}{2} * 7 * 14[/tex]
= 7 * 7
= 49 cm²
Area of the figure = area of figure I + area of figure II + area of figure II
= 128 + 12 + 49
= 189 cm²[tex]\text{area of figure III = \dfrac{1}{2}*b*h}[/tex]
Answer:
189 cm²
area of triangle:
1/2 * base * height
1/2 * 7 * (6+4+4)
49 cm²
area of rectangle:
Length * Width
8 * 10
80 cm²
area of rectangle 2:
Length * Width
6 * 8
48 cm²
area of small rectangle:
Length * Width
4 * 3
12 cm²
total area:
49 + 48 + 12 + 80
189 cm²

Angle θ is in standard position. if sin(θ) = − 1 3 , and π < θ < 3π 2 , find cos(θ).
The value of the angle θ is 160.52° then the value of the cosine will be negative 0.9428.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Angle θ is in standard position.
If sin(θ) = − 1/3 , and π < θ < 3π/2
Then the angle will be
[tex]\theta = \sin ^{-1}\dfrac{-1}{3}\\\\\theta = -19.47[/tex]
Then add 180 degrees, then we have
[tex]\theta = -19.47 + 180\\\\\theta = 160.52[/tex]
Then the value of the cosine will be
[tex]\cos 160.52^o=-0.9428[/tex]

All the line segments of this 22-gon meet at right angles. The radius of the smallest circle that will completely surround the polygon is
Answer:
√61 ≈ 7.81
Step-by-step explanation:
It appears that the polygon can be enclosed by a rectangle that is 12 units wide and 10 units high. The enclosing circle is the one that will circumscribe that rectange. Its radius is half the length of the diagonal, so is ...
(1/2)√(12² +10²) = 1/2√244 = √61
The smallest circle that will surround the polygon will have a radius of √61 ≈ 7.81 units.
_____
The Pythagorean theorem is used to find the length of the diagonal. It tells you the square of the diagonal is the sum of the squares of the sides of the rectangle. Our radius is half the diagonal, so is half the square root of the sum of the squares of the side lengths.

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
12, 10, 8,.........
This is______sequence and the _______is equal to _________.
Answer:
Step-by-step explanation:
This is an arithmetic sequence and the common difference = - 2
You might be a little puzzled by the minus sign in front of the two. You can look at the sequence for the answer. It is going down. A plus 2 would make it go up. Minus signs are always a bit tricky and you have to watch out what you do with them. But the rule is simple
a minus common difference produces a sequence that goes down.a plus common difference produces a squence that goes up.You know that this is an arithmetic sequence because the common difference can be found by adding or subtracting a number from the previous term to get to the next term.
A geometrice sequence would use multiplication or division to get from one term to the next.
Substitution method please
Answer:
x = 3, y = -2
Step-by-step explanation:
Solving the bottom equation for y, we have y = 4 - 2x. Substitute that into the top equation, and solve for x.
4x - 3(4 -2x) = 18
4x - 12 + 6x = 18
10x - 12 = 18
10x = 30
x = 3
From this, we have y = 4 - 2(3) = 4 - 6 = -2

Answer:
Yes, AB is tangentStep-by-step explanation:
The tangent is perpendicular to the radius. The given triangle is right if AB is tangent.
Use Pythagorean to verify
20² = 16² + 12²400 = 256 + 144400 = 400Confirmed
Answer:
AB is tangent to the circle
Step-by-step explanation:
The tangent of a circle is always perpendicular (at a right angle) to the radius. Therefore, if AB is the tangent to the circle, the angle between the radius and AB will be 90° (and ΔBAO will be a right triangle).
Pythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleGiven:
a = 12b = 16c = 20Substitute the given values into the formula:
[tex]\implies 12^2+16^2=20^2[/tex]
[tex]\implies 144+256=400[/tex]
[tex]\implies 400=400[/tex]
Therefore, as ΔBAO is a right triangle with ∠BAO = 90°, AB is tangent to the circle.
The algebraic expression of the SUM is n²+2n. What is the common difference and first term
Answer:
see explanation
Step-by-step explanation:
substitute n = 1, 2 into the sum rule
1² + 2(1) = 1 + 2 = 3 , then
a₁ = 3
2² + 2(2) = 4 + 4 = 8 , then
a₁ + a₂ = 8
3 + a₂ = 8 ( subtract 3 from both sides )
a₂ = 5
then
common difference d = a₂ - a₁ = 5 - 3 = 2
First term is 3 and common difference = 2

Determine the equation of the parabola that opens up, has focus (−2,7), and a focal diameter of 24.
Answer:
[tex] \sf{(x + 2)}^{2} = 24(y -1) [/tex]
Step-by-step explanation:
Given:
focus(h,k)= (−2,7)
Focal Diameter (Latus rectum) = 24
To find:
Equation of parabola= ?
Solution:
Focal Diameter also known as letus rectum is the segment which passes through Focus and intersects the Axis of parabola having end point at the wall of of parabola.
Focal Diameter = 24
[tex]4p = 24 \\ p = \cancel\frac{ 24}{ 4} = 6 \\ \fbox{p = a = 6}[/tex]
Now to find the equation of parabola we need the vertex(h,v).
Vertex is a point on parabola which lies in same axis of symmetry at equidistant from the directrix and Focus and the distance is one fourth of letus rectum.
Now,
[tex] \sf \: (h,v) = (h,k-p) \\ \sf \: (h,v)= (-2,7-6) \\\sf \: \fbox{ (h,v) = (-2,1)}[/tex]
Equation of parabola
[tex]\sf{(x-h)}^{2} = 4a(y - v)[/tex]
Substituting the cordinate of vertex in above equation,
[tex] \sf{(x - (-2)}^{2} = 4 \times ( 6)(y-1 ) \\ \sf{(x + 2)}^{2} = 24(y -1)[/tex]
This is the final answer.

Intersecting Secant-Tangent Theorem
The square of the tangent is equal to the product of the external secant segment and the secant.
Given:
tangent = AE = 12external secant segment = EC = 8secant = ED = 18 + xAE² = EC · ED
⇒ 12² = 8(18 + x)
⇒ 144 = 144 + 8x
⇒ 0 = 8x
⇒ x = 0
ED = 18 + x
= 18 + 0
= 18

Is FGH ~ JKL? If so, identify the similarity postulate or theorem that applies.
Answer: D
Step-by-step explanation:
There are two pairs of congruent angles.
The two triangles FGH and JKL are similar to each other by Angle-Angle property. Hence, option D is correct.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
In the given figure we can see that the two triangles FGH and JKL have two angles equal that is ∠f =∠J = 30° and ∠L = ∠H =55°. Two angles are similar then the triangles are similar.
Hence, option D is correct.

Answer:
The solution to the set of linear equations is:
[tex](5,-4)[/tex]
Step-by-step explanation:
Hey there!
In order to solve this system of equations, we can put the equations equal to each other since both equations are equal to y
[tex]6-2x=-4x+16[/tex]
Now we simplify
[tex]2x=10[/tex] ---> [tex]x=5[/tex]
So now that we know that x is equal to 5, we can find the value of y
let's substitute it in one of the equations
[tex]y=6-2(5)[/tex] ---> [tex]y=-4[/tex]
So now we know that the point where the two equations intersect is:
[tex](5,-4)[/tex]
