Answer:
(7) AB is a tangent , (8) AB is not a tangent
Step-by-step explanation:
the angle between a tangent and the radius is 90°
if AB is a tangent then Δ ABC is right with hypotenuse AC
using Pythagoras' identity
the square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides.
if AC² = AB² + BC² , then AB is a tangent to the circle
(7)
AC² = 34² = 1156
AB² + BC² = 30² + 16² = 900 + 256 = 1156
since AC² = AB² + BC² , then AB is a tangent to the circle
(8)
AC² = 28² = 784
AB² + BC² = 21² + 20² = 441 + 400 = 841
since AC² ≠ AB² + BC² , then AB is not a tangent to the circle
Helena sketches a circular backyard skating pond that fits into a square section of her yard. In her sketch, what is the area of the shaded region?
Answer:
The area of the shaded region equals 21.43 sq. units.
Step-by-step explanation:
Why do we use area?When calculating how much material is needed to cover a wooden table, how many tiles are needed to tile the floor, how much space is needed for a parking lot, how much paint is needed for the walls, etc., we employ the notion of area.
Given, A circle is circumscribed in the square,
Area of shaded region = area of square - area of circle
Area of square = Side²
= 10 × 10 = 100 sq. units,
Area of circle = Πr²
Radius = Diameter / 2
radius = 10 / 2 = 5 unitsArea of circle = Πr²
Radius = Diameter / 2
radius = 10 / 2 = 5 units
Area of circle = 22/7 × 5 × 5
= 78.57 sq. units
Area of shaded region = 100 - 78.57,
Area of shaded region = 21.43 sq. units
A bag holds 13 marbles. 6 are blue, 2 are green, and 5 are red.
Match the events on the left with probabilities on the right.
The probabilities of the events and their values are shown below
Matching the probabilities of the eventsThe total number of marbles in the bag is 13, with 6 blue, 2 green, and 5 red.
P(Blue or Green) represents the probability of selecting a blue or green marble on the first pick.
This is calculated as follows:
P(Blue or Green) = P(Blue) + P(Green)
= 6/13 + 2/13
= 61.5%
P(Blue and Green) represents the probability of selecting a blue marble and a green marble on two consecutive picks, with replacement.
Therefore:
P(Blue and Green) = P(Blue) * P(Green)
= (6/13) * (2/13)
= 7.1%
P(Blue and Green) represents the probability of selecting a blue marble and a green marble on two consecutive picks, without replacement.
Therefore:
P(Blue and Green) = P(Blue) * P(Green)
= (6/13) * (2/12)
= 7.7%
P(Blue) represents the probability of selecting a blue marble on the first pick.
This is simply the proportion of blue marbles in the bag:
P(Blue) = 46.2%

Dario walks from his house to a comic book store along the route shown. Distances in the coordinate plane are in units of miles. How many miles does Dario walk to reach the comic book store
The distance walked by Dario from to reach comic book store is 1.4 miles.
What is distance?Displacement and distance are two terms that, while they appear to imply the same thing, have quite different definitions and meanings. Displacement is the measurement of "how much space an item has covered while it has been in motion," whereas distance is the indication of "how much ground an object has covered during its motion." Let's examine the distinction between displacement and distance in this essay.
For the given route we have:
House to jewelry store:
0.2 - (-0.5) = 0.2 + 0.5 = 0.7 miles.
Jewelry store to bank:
0.6 - 0.2 = 0.4 miles.
Bank to comic book store:
-0.5 -(-0.8) = -0.5 + 0.8 = 0.3 miles.
House to comic book store:
0.7 + 0.4 + 0.3 = 1.4 miles.
Hence, the distance walked by Dario from to reach comic book store is 1.4 miles.

Katya owns two cockatoos, an older white cockatoo and a younger Galah cockatoo. At present, the sum of the cockatoos' ages is 44 years. In n years, where n > 0, the white cockatoo's age will be four times the Galah cockatoo's age. If n is an integer, determine the possible present ages of each cockatoo.
The possible present ages of each cockatoo, given the sum of the cockatoos would be Galah cockatoo is currently 10 years old and the white cockatoo would be 34 years old
How to find the ages of the cockatoos?Let's use variables to represent the present ages of the two cockatoos. Let W be the present age of the white cockatoo and G be the present age of the Galah cockatoo. We're given that the sum of their ages is 44 years:
W + G = 44 (1)
In n years, the white cockatoo will be W + n years old, and the Galah cockatoo will be G + n years old:
W + n = 4(G + n) (2)
Since n > 0, 5G - 44 must be positive. We can try different values of G to find possible integer values for n.
For G = 8:
44 - 5(8) = 4
4 = -3n
n is not an integer.
For G = 10:
44 - 5(10) = -6
-6 = -3n
n = 2
So one possibility is that the Galah cockatoo is currently 10 years old. In this case, the white cockatoo would be 34 years old (since W + G = 44).

describe the key features que f the graph of the quadratic function f(x)=x^2-8-20
The graph is a parabola, with a vertex at (4,-4), an axis of symmetry at x = 4, x-intercepts at x = 10 and x = -2, and a y-intercept at (0,-20).
Define quadratic functionA quadratic function is a type of polynomial function of degree 2. It can be defined as a function in which the highest power of the independent variable x is 2.
The quadratic function f(x) = x² - 8x - 20 has a graph that is a parabola with a vertical axis of symmetry.
Vertex: The vertex of the parabola can be found using the formula x = -b/2a, where a and b are the coefficients of x² and x respectively.
In this case, a = 1 and b = -8, so the x-coordinate of the vertex is x = -(-8)/(2×1) = 4.
To find the y-coordinate of the vertex, substitute x = 4 into the equation: f(4) = 4² - 8(4) - 20 = -4. Therefore, the vertex is located at (4,-4).
Axis of symmetry: The axis of symmetry of the parabola is a vertical line passing through the vertex.
In this case, the axis of symmetry is the line x = 4.
Intercepts: To find the x-intercepts set y = 0 and solve for x: x² - 8x - 20 =0.
this quadratic equation can be factored as (x - 10)(x + 2) = 0
so the x-intercepts are x = 10 and x = -2.
To find the y-intercept, set x = 0 and evaluate f(0) = 0² - 8(0) - 20 = -20. Therefore, the y-intercept is (0,-20).
Image is attached below.
The graph is a upward-facing parabola, with a vertex at (4,-4), an axis of symmetry at x = 4, x-intercepts at x = 10 and x = -2, and a y-intercept at (0,-20).

The three-dimensional figure below is a cylinder with a hole in the shape of a rectangular prism going through the center of it. The radius is 10 yards. Find the volume of the solid in cubic yards, rounded to the nearest ten.
The volume of the solid with a hole in the shape of a rectangular prism passing through the center of a cylinder with a radius of 10 yards is approximately 1410 cubic yards, rounded to the nearest ten.
The cylinder with the hole can be viewed as the difference of two solids: the cylinder and the rectangular prism. The volume of the cylinder is given by the formula V_cyl = π[tex]r^2h[/tex], where r is the radius and h is the height.
The height of the cylinder is equal to the height of the rectangular prism that passes through its center. The height of the rectangular prism is given as 12 yards, which is also the diameter of the cylinder. Therefore, the height of the cylinder is h = 12/2 = 6 yards.
The volume of the cylinder is therefore V_cyl = π[tex](10)^2(6)[/tex] = 600π cubic yards.
The rectangular prism has a length of 20 yards, a width of 10 yards, and a height of 12 yards. Therefore, its volume is V_prism = 20 × 10 × 12 = 2400 cubic yards.
The volume of the solid with the hole is then:
V = V_cyl - V_prism = 600π - 2400 = 600(π - 4) ≈ 1412.2 cubic yards.
Therefore, the volume of the solid is approximately 1410 cubic yards.
