The center of a circle is placed on the origin of a coordinate plane as shown below. The radius of the circle is 10 units. If the point (-6, y) lies on the circle, what is y?
Answer:
(-6, 8)
Step-by-step explanation:
Since the radius is 10 units and the center is on the origin of the circle, the distance from the origin to the point (-6, y) must be 10.
We can use the distance formula given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We will let the point (-6, y) be (x₂, y₂) and the origin point (0, 0) be (x₁, y₁). The distance is 10. Substitute:
[tex]10=\sqrt{((-6)-(0))^2+((y)-(0))^2}[/tex]
Simplify:
[tex]10=\sqrt{(-6)^2+(y)^2}[/tex]
Square both sides and simplify:
[tex]100=36+y^2[/tex]
Solve for y:
[tex]y^2=64[/tex]
Take the square root of both sides:
[tex]y=\pm\sqrt{64}=\pm 8[/tex]
Since our point is in QII, y must be positive. Hence, we will use the positive case. So, y = 8.
Our point is (-6, 8).

Evaluate the following:
F(x) = 4x - 9 for f(5)
Answer:
f(5)=11
Step-by-step explanation:
f(x)=4x-9
f(5)=4(5)-9
f(5)=20-9
f(5)=11
Answer:
f(5) = 11
Step-by-step explanation:
F(x) = 4x - 9 for f(5)
x gets replaced with 5
f(5) = 4(5) - 9
f(5) = 20 - 9
f(5) = 11

Step-by-step explanation:
i looked it up :)
Answer:
AC = 11.4
Step-by-step explanation:
6/sin 23 = AC/sin 132
6 sin 132/sin 23 = AC
AC = 11.4
If a box has 5 red, 3 green, and 4 blue jelly beans, then what is the probability of choosing
at random a red jelly bean?
7/12, 5/12, 1/12, 2/7
Answer:
2/7
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
All the beans are equally likely to be chosen, so the bottom (denominator) of the fraction is 12 (there are 12 beans in the box).
The numerator is 5 because that's the number of red beans in the box.

The area of ΔNOP is approximately 2.11 square centimeters, rounded to the nearest 10th of a square centimeter.
How to find the area of a triangle whose vertices' coordinates are given?Suppose the vertices of the considered triangle ABC are on A(A_x,A_y), B(B_x,B_y), C(C_x,C_y), then, the area of the triangle is given by:
[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]
We are given that;
Side P=2.5cm
Side N=2.3cm
Angle O=71
Now, to find the area of a triangle, we can use the formula:
A = (1/2) * base * height
where base and height are two sides of the triangle that form a right angle, or any two sides of the triangle if we know the included angle between them.
In this case, we are given the lengths of two sides, p and n, and the measure of one angle, ∠O. To find the area, we need to first find the length of the third side, OP, using the Law of Cosines:
OP² = p² + n² - 2pn cos(∠O)
OP² = 2.5² + 2.3² - 2(2.5)(2.3) cos(71°)
OP² = 4.2694
OP ≈ 2.067 cm
Now we can use the formula for the area of a triangle:
A = (1/2) * OP * n * sin(∠O)
A = (1/2) * 2.067 * 2.3 * sin(71°)
A ≈ 2.11 cm²
Therefore, the area of triangle NOP will be 2.11 square centimeter.

Answer:
90°
Step-by-step explanation:
There is no work. We know the right angle in the triangle and the x are supplementary. Meaning, they add up to 180 degrees. Therefore, 180-90 = 90. Think of it as a full triangle. If the 40 at the top was not half, but a full triangle, the 40 at the top would become 80. The 50 in the bottom left would mean there would be a 50 in the bottom right when you mirror the triangle. Therefore, you also need x to be 90 to make it a right triangle.

Answer:
ΔABC≅ΔDEC by AAS
Step-by-step explanation:
You can use the AAS method of congruency.
Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent

What number is represented by point P?
Answer:
0.0057
Step-by-step explanation:
Narrow it down.The point P is between 5 * 10^-3 and and 6*10^-3When you go to the bottom line, P is on the 7th division from the left. Going from left to right increases PP is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.One of the answers is 5.7 * 10^-3The other answer is .0057I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it. If it is not correct, then 5.7 * 10^-3 is the answer.PLEASE HELP FAST 100 POINTS!
Construct the graph of the following function and identify its zeros on the same document. f(x) = (-x + 2)(x + 1)(x +2). Upload your document in the box below.
Answer:
Given function:
f(x) = (-x + 2)(x + 1)(x +2)We can rewrite it as:
f(x) = - (x - 2)(x + 1)(x +2)Zeros are:
- (x - 2)(x + 1)(x +2) = 0x - 2 = 0 ⇒ x = 2x + 1 = 0 ⇒ x = -1x + 2 = 0 ⇒ x = -2As leading coefficient is negative the function is decreasing.
As the function is of degree 3, it is odd.
Considering the above two factors we can define the shape of the graph:
It is decreasing function with one local minimum and one local maximum.See the graph and zero's reflected.
