A circumscribed angle is an angle that has its vertex on the circumference of a circle and whose sides are chords of the circle. The measure of a circumscribed angle is equal to half the measure of the intercepted arc. Circumscribed angles are important in geometry because they are used to prove theorems about angles, chords, and arcs in circles. The opposite angles of a cyclic quadrilateral are always supplementary, and the sum of the angles in a cyclic polygon is always equal to (n-2)180 degrees, where n is the number of sides of the polygon.
AD=7, BD=3, DE=6. Find BC
Answer:
the answer to this is 10 i think sorry if it is wrong
Step-by-step explanation:
The triangles are similar and the measure of BC = 60/7 units
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔABC
Let the second triangle be ΔADE
Now , ΔABC and ΔADE are similar triangles
where corresponding sides of similar triangles are in the same ratio
So , AD / AB = DE / BC
On simplifying , we get
7 / 10 = 6 / BC
Multiply by BC on both sides , we get
BC ( 7/10 ) = 6
Multiply by 10 on both sides , we get
7BC = 60
Divide by 7 on both sides , we get
BC = 60/7
Hence , the measure of BC = 60/7 units

The volume of a cone is 13.4m cubed and the radius is 3.2m what is the height
Answer:
The height is 1.25m.
Step-by-step explanation:
Volume = 1/3 πr²h
Given:
V = 13.4 m³
r = 3.2 m
Asked: height (h)
Substitute the formula with the given values then solve
13.4m³ = 1/3π(3.2m)²h
13.4(3) = 10.24πh
40.2 = 10.24πh
h = 40.2/10.24π
h = 1.25m
The height of the cone is 1.25 meters.
We know that the volume of the cone is given by
V = (1 / 3) * π * r ^2 * h................equation 1
where,
V is the volume of the cone.
r is the radius of the cone's base
h is the height
The volume and radius of the cone are given,
V = 13.4 m
r = 3.2m
substituting these values in equation 1 we get,
13.4 = (1 / 3) * 3.14 * 3.2 ^ 2 * h
on simplifying further
13.4 = 10.717 * h
h = 1.25m
The height of the cone is 1.25 meters.

The volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis is 51π cubic units.
What is the volume of the solid obtained by rotating the region in the first quadrant bounded by the given curve about the y - axis?To find the volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis, we can use the method of cylindrical shells.
The formula for the volume using cylindrical shells is:
V = 2π ∫ [a, b] x * h(x) dx
Where:
- V is the volume of the solid
- π represents the mathematical constant pi
- [a, b] is the interval over which we are integrating
- x is the variable representing the x-axis
- h(x) is the height of the cylindrical shell at a given x-value
In this case, we need to solve for x in terms of y to express the equation in terms of y.
Rearranging the given equation:
x = 5 ± √(1 - y)
Since we are only interested in the region in the first quadrant, we take the positive square root:
x = 5 + √(1 - y)
Now we can rewrite the volume formula with respect to y:
V = 2π ∫ [c, d] x * h(y) dy
Where:
- [c, d] is the interval of y-values that correspond to the region in the first quadrant
To determine the interval [c, d], we set the equation equal to zero and solve for y:
1 - (x - 5)² = 0
Expanding and rearranging the equation:
(x - 5)² = 1
x - 5 = ±√1
x = 5 ± 1
Since we are only interested in the region in the first quadrant, we take the value x = 6:
x = 6
Now we can evaluate the integral to find the volume:
V = 2π ∫ [0, 1] x * h(y) dy
Where h(y) represents the height of the cylindrical shell at a given y-value.
Integrating the expression:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * h(y) dy
To find h(y), we need to determine the distance between the y-axis and the curve at a given y-value. Since the curve is symmetric, h(y) is simply the x-coordinate at that point:
h(y) = 5 + √(1 - y)
Substituting this expression back into the integral:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
Now, we can evaluate this integral to find the volume
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
To simplify the integral, let's expand the expression:
V = 2π ∫ [0, 1] (25 + 10√(1 - y) + 1 - y) dy
V = 2π ∫ [0, 1] (26 + 10√(1 - y) - y) dy
Now, let's integrate term by term:
\(V = 2\pi [26y + 10/3 * (1 - y)^\frac{3}{2} - 1/2 * y^2]\)] evaluated from 0 to 1
V = \(2\pi [(26 + 10/3 * (1 - 1)^\frac{3}{2} - 1/2 * 1^2) - (26 * 0 + 10/3 * (1 - 0)^\frac{3}{2} - 1/2 * 0^2)]\)
V = 2π [(26 + 0 - 1/2) - (0 + 10/3 - 0)]
V = 2π (25.5)
V = 51π cubic units

Carl is making accessories for the soccer team. He uses 773.85 inches of fabric on headbands for 29 players and 4 coaches. He also uses 279.56 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
23.45 inches fabric was used on a headband and 9.64 inches fabric was used on a wristband for each player.
No. of players = 29
No. of coaches = 4
Total fabric used for headbands = 773.85 inches
Total no. of people for headbands = 29 + 4
= 33
Fabric used for headband for 1 person = 773.85/33
= 23.45 inches
Total fabric used for wristbands = 279.56 inches
Total no. of people for wristbands = 29
Fabric used for headband for 1 person = 279.56/29
= 9.64 inches

Find the distance traveled in 25 seconds by an object traveling at a velocity of v(t) = 20 + 5cos(t) feet per second
Answer:
499.338 feet
Step-by-step explanation:
You want to know the distance traveled by an object in 25 seconds when its velocity is described by 20+5cos(t) feet per second.
DistanceThe distance an object travels is the integral of its velocity. For the given velocity and time period, the distance is ...
\(\displaystyle d=\int_0^{25}{v(t)}\,dt=\int_0^{25}{(20+5\cos(t))}\,dt=(20t+5\sin(t))|_0^{25}\\\\d=500+5\sin(25)\approx\boxed{499.338\quad\text{feet}}\)
The distance traveled in 25 seconds is 499.33 feet.
It is required to find the distance traveled in 25 seconds.
What is distance?The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given:
We have to find the distance , we will integrate v(t) from 0 to 25 second.
Consider an object traveling at constant velocity v = k. Then, each second, it travels k feet, so after t seconds, the distance traveled is k*t.
Now, suppose its speed increases by 1 feet/sec . So, estimate for distance traveled after t seconds is
1 + 2 + 3 + 4 + ... + t = t(t+1)/2, or approximately 1/2 t^2.
According to given question we have
Given a velocity function v, the distance s is figured by taking the integral. In this case,
v = 20 + 5 cos(t)
s = 20t + 5 sin(t) from 0 to 25
= s(45)-s(0)
s(0) = 0
so, the distance is
s(25) = 20*25 + 5sin(25)
= 500 -0.661
=499.33 feet.
Therefore, the distance traveled in 25 seconds is 499.33 feet.

PLEASE HELP!!!
The numeric value of the function when x = -2/3 is given by:
\(f\left(-\frac{2}{3}\right) = \frac{8}{27}\)
How to find the numeric value of a function?
The numeric value of a function is found replacing each instance of x by the value that we want to find.
In this problem, the expression is given by:
\(f(x) = -\frac{3}{2}x^3 - \frac{1}{3}x^2\)
For this problem, we want to find the numeric value of the function when x = -2/3, hence each of the two instances of x have to be replaced by -2/3, so:
\(f(x) = -\frac{3}{2}x^3 - \frac{1}{3}x^2\)
\(f\left(-\frac{2}{3}\right) = -\frac{3}{2}(-\frac{2}{3}\right)^3 - \frac{1}{3}(-\frac{2}{3}\right)^2\)
\(f\left(-\frac{2}{3}\right) = \frac{3 \times 2^3}{2 \times 3^3} - \frac{2^2}{3^3}\)
\(f\left(-\frac{2}{3}\right) = \frac{12}{3^3} - \frac{4}{3^3}\)
\(f\left(-\frac{2}{3}\right) = \frac{8}{27}\)

Answer:
1.6 times or 60% more than
Step-by-step explanation:
The question seems to be asking about the growth factor in the given exponential function.
Exponential functionA generic exponential function will have the form ...
quantity = (initial value) × (growth factor)^(number of intervals)
Comparing this form to the given formula ...
f(x) = 58 × 1.6^x
we see the "growth factor" is 1.6. This is the multiplier from one interval (year) to the next.
Each year the expected number of birds is 1.6 times the number the year before.

Additional comment
A growth factor is sometimes expressed in terms of a growth rate, usually a percentage.
growth factor = 1 + growth rate
1.6 = 1 + 0.60 = 1 + 60%
The growth rate of this bird population is 60% per year. Each year, the population is 60% more than the year before.

Find the slope of identity function using points (0,0) and ( 3,3) then from two points (0,0) and (-3,-3). Is there any change in its slope?
There is no change in its slope as initial and final slope is 1.
What is slope?
In arithmetic, the slope or gradient of a line may be a variety that describes each the direction and therefore the abruptness of the line.
Main body:
formula for slope with two points form is =
y -y₁ =( y₂-y₁ /x₂-x₁ )(x - x₁)
according to question ,
points are (0,0) and (3,3)
y - 0 = (3-0/3-0)(x -0)
y = 3/3 *x
y = x
