In the diagram, BC is a radius of C. Determine whether AB is tangent to C. Explain your reasoning.
Answers
Answer:
No, AB is not tangent to C.
If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.
3²+6²=7²
9+36=49
45=49 Since this is false, it's not a right angle, and AB is not tangent.
Step-by-step explanation:
No, AB is not tangent to C.
If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.
3²+6²=7²
9+36=49
45=49 Since this is false, it's not a right angle, and AB is not tangent.
The line segment AB is not a tangent to C since it is not perpendicular to BC.
What is the relationship between a tangent and the radius from the point it touches the circle?The tangent is perpendicular to the radius of the circle joined from the center to the point at which the tangent touches the circle.
What is the Pythagorean theorem?The Pythagorean theorem states that in a right-angled triangle, the sum of the squares of the sides is equal to the square of the hypotenuse.
z² = x² + y²
The line segment AB would be a tangent if the triangle ABC is a right-angled triangle. We can use the Pythagorean theorem.
7² = 3² + 6²
49 = 9 +36
49 = 45
This is incorrect.
49 ≠ 45
This means that the triangle is not a right-angled triangle. This in turn means that AB is not a tangent to C.
We have determined that AB is not a tangent to C as it is not perpendicular to BC.

Answer:
(a, b) = (√2/2, √2/2) . . . . . choice C in each case
Step-by-step explanation:
The points on a unit circle will not have coordinate values greater than 1 (eliminates √2). The coordinates will only be 0 or 1 if the point is on one of the axes. The coordinates (a, b) of the point at 45° are ...
(cos(45°), sin(45°)) = (a, b) = (√2/2, √2/2)
The coordinate of point (a, b) is (√2/2, √2/2)
Coordinate of a point on a circleNote that the points on a unit circle will not have coordinate values greater than 1.
The coordinates will only be 0 or 1 if the point is on one of the axes. The coordinates (a, b) of the point at 45° is given according to the coordinate point (cos45, sin45)
a = cos45 = √2/2
b = sin45 = √2/2
Hence the coordinate of point (a, b) is (√2/2, √2/2)

Answer:
x = 4
Step-by-step explanation:
x + x + 6 + 6 = x + 8 + 8
2x + 12 = x + 16
2x + 12 - 12 = x + 16 - 12
2x + 0 = x + 4
2x = x + 4
2x - x = x + 4 - x
2x - x = x - x + 4
x = 0x + 4
x = 0 + 4
x = 4
Chequando Respuesta :
x = 4
x + x + 6 + 6 = x + 8 + 8
(4) + (4) + 6 + 6 = (4) + 8 + 8
4 + 4 + 6 + 6 = 4 + 8 + 8
8 + 6 + 6 = 12 + 8
14 + 6 = 20
20 = 20
Ambos lados de la ecuacio'n son igual cuando x = 4, y esto confirma que la respuesta es corecta, que x = 4 en este problema.

Answers
Answer:
The correct answer is B.
Step-by-step explanation:
Since Chandler, Jamal, Allison, and Qi are given the following problem: "In 1982, Wayne Gretsky set a record for the greatest number of hockey goals in one season with 92 goals. If a player has scored 60 goals this season and averages 2 goals per game, how many additional games must he play to break the record? ", And each student writes an inequality to represent the situation:
Chandler wrote 60 + 2g ≥ 92
Jamal wrote 60 + 2g> 92
Allison wrote 60 + 2g <92
Qi wrote 60 + 2g ≤ 92
To determine whose inequality is correct, the following calculation must be performed:
92 - 60 = 32
32/2 = 16
Chandler: 60 + 2x16 ≥ 92
Thus, Chandler wrote the correct option.

The exponential decay function is given by y=2000×0.9ˣ and the stock will be worth $1180.98 after a period of 5 years.
What is exponential decay function?In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)ˣ wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.
Given here: The value of the stock in 2012 was $2000 and the value decreases each year by 10%
We know the exponential decay is given by y=a(1-b)ˣ
where x is the number of years and 1-b is the decreasing factor
Thus based on the given information we can construct the exponential decay function as y=2000(1-10%)ˣ
or y=2000×0.9ˣ
Therefor in 5 years i.e in 2017 the stock will be worth
y=2000×0.9⁵
=$1180.98
Hence, The exponential decay function is given by y=2000×0.9ˣ and the stock will be worth $1180.98 after a period of 5 years.

In Nebraska, Mr. Dukarelli's 11th grade class consisting of 27 students was surveyed and 34.6 percent of the students reported that they had at least two siblings. The average 11th grade class size in the state is 27.

Answers
95141 1404 393
Answer:
b. 28,300
Step-by-step explanation:
The estimated number of 11th grade students in the state is ...
(1600 classes)(27 students/class) = 43,200
About 34.6% are estimated to have 2 or more siblings, so the remaining 100%-34.6% = 65.4% are estimated to have fewer than 2 siblings.
Translated to a number of students, that percentage is ...
0.654 × 43,200 = 28,252.8 ≈ 28,300
A good estimate of the number of students with fewer than 2 siblings is 28,300.
