Considering the circle of the given equation, and comparing to the standard equation of a circle, it is found that the given circle has radius is of [tex]\frac{1}{5}[/tex].
What is the equation of a circle?The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In this problem, the equation is given by:
[tex]\left(x + \frac{1}{5}\right)^2 + \left(y - \frac{2}{5}\right)^2 = \frac{1}{25}[/tex]
Hence, the radius is found as follows.
[tex]r^2 = \frac{1}{25}[/tex]
[tex]r = \sqrt{\frac{1}{25}}[/tex]
[tex]r = \frac{1}{5}[/tex]

Functions must pass the vertical line test. This means that for every x value there must be ONLY ONE y value.
We can see in this table that the x value 25 has two different y values. Therefore, this is NOT a function.
Hope this helps!
Answer:
yes
Step-by-step explanation:
If the line only goes through one point once than yes. Vertical line test.
Note: "While a function may NOT have two y-values assigned to the same x-value, it may have two x-values assigned to the same y-value. Function: each x-value has only ONE y-value!"

∠A and ∠B are supplementary. The measure of ∠A is 96°. What is the measure of ∠B? Enter your answer in the box. °
Answer:
∠B = 84
Step-by-step explanation:
Supplementary angles add up to 180°, You would subtract 96 from 180 to find angle B.
Answer:
=> ∠B = 84
Step-by-step explanation:
Given :
∠A + ∠B = 180°
∠A = 96°
=> 96° + ∠B = 180
=> ∠B = 180-96
=> ∠B = 84

Solve the equation 4 ( c - 3 ) = 8
Answer:
c=5
Step-by-step explanation:
4(c-3)=8 Distribute
4c-12=8 Add 12 to both sides
4c=20 Divide by 4 on both sides
c=5
Answer:
c = 5Step-by-step explanation:
METHOD 1:
4(c - 3) = 8 |divide both sides by 4
4(c - 3)/4 = 8/4
c - 3 = 2 |add 3 to both sides
c - 3 + 3 = 2 + 3
c = 5
METHOD 2:
4(c - 3) = 8 |use the distributive property: a(b - c) = ab - ac
4 · c - 4 · 3 = 8
4c - 12 = 8 |add 12 to both sides
4c - 12 + 12 = 8 + 12
4c = 20 |divide both sides by 4
4c/4 = 20/4
c = 5

By evaluating the given relation, we conclude that the correct options are A, D, and G.
How to check if the points are on the graph?
We have the relation:
k = ∛(V/7)
Such that this relation gives us pairs of the form (V, k).
So, to check if the points belong to the graph of the relation, we need to evaluate the points on the given relation and see if the relation is true.
A) (0, 0) gives:
Evaluating in V = 0
k = ∛(0/7) = 0
So this point belongs.
B) (1, 1) gives:
k= ∛(1/7) = 0.52
So we have the point (1, 0.52) and the point (1, 1) then does not belong to the graph.
We just need to do that for all the points, evaluate V and see if k gives the same value as in the point.
With this method, we will see that the correct options are:
D) (7, 1)
k= ∛(7/7) = 1
G) (56, 2)
k= ∛(56/7) = ∛(8) = 2

EASY GIVING BRAINLIEST JUST GRAPH TO FIND ANSWER While warming up for a game, two basketball players shoot balls in parabolic paths. The path of the first player's ball can be represented by the function g(x) = –2x2 + 13x + 7, where x represents the distance from the coach. The path of the second player's ball can be represented by the function h(x) = –x2 + 4x + 21.
Part A: Find the distances in which the two basketball paths will cross. Show all necessary calculations.
Answer:
2 ft, 7 ft
Step-by-step explanation:
We are interested in the values of x such that g(x) = h(x). These will be solutions of the difference g(x) -h(x) = 0. Hence the x-intercepts of a graph of g(x) -h(x) will be solutions to the problem.
__
The graph shows the difference between the paths will be zero at distances of 2 feet and 7 feet.
The diagram shows the entrance to a tunnel.
The circular arc has a radius of 3m and center O.
AB is horizontal and angle AOB = 120°.
During a storm the tunnel filled with water, to the level shown by the shaded area in the diagram.
Calculate the shaded area.
Step-by-step explanation:
it filled up half the circle (up to the center point) - if we had a full circle. but a little bit is cut off (below AB).
what we see is that the shaded area is the sum of the area of the triangle AOB and 2 equally sized circle segment areas left and right of AOB.
since we are dealing with a half-circle, we have 180° in total. 120° are taken by AOB, so, that leaves us with 180-120 = 60° for both circle segments (so, one has an angle of 30°).
and 2×30° = 1×60°, so we can calculate the area of one 60° segment instead of two 30° segments.
AOB is an isoceles triangle (the legs are equally long, and therefore also the 2 side angles are equal).
the area of this triangle AOB is
1/2 × a × b × sin(C) = 1/2 × 3 × 3 × sin(120) =
= 3.897114317... m²
a circle segment area of 60° is 60/360 = 1/6 of the full circle area (as a full circle = 360°).
so, it's area is
pi×r² × 1/6 = pi×3²/6 = pi×3/2 = 4.71238898... m²
so, the total area of the shaded area is
3.897114317... m² + 4.71238898... m² =
= 8.609503297... m²
The area of the shaded portion of the circle is A = 8.61 m²
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the area of the shaded region be A
Let the radius of the circle be r = 3 m
The triangle ΔAOB is an isosceles triangle with side lengths = 3m
The area of the triangle ΔAOB = ( 1/2 ) x 3 x 3 x sin (120)
On simplifying the equation , we get
The area of the triangle ΔAOB = 3.897 m²
Now ,
There are 2 sectors , with sector angle = 30°
The area of the two sectors = 2 x ( 30/360 ) x π x 3²
On simplifying the equation , we get
The area of the two sectors = 2 x 2.357
The area of the two sectors = 4.714 m²
Now ,
The area of the shaded region of circle A = area of the two sectors + area of the triangle ΔAOB
Substituting the values in the equation , we get
The area of the shaded region A = 4.714 + 3.897
The area of the shaded region A = 8.611 m²
Therefore , the value of A is 8.611 m²
Hence , the area is 8.611 m²

Make x the subject K(x-a)=t
Answer:
x = t+ka/k
Step-by-step explanation:
First you take letter k and place it after =sign which brings (x-a) = t/k because if you shift any number or letter after the = sign it has to be the opposite sign. for instance if it's positive, it will turn negative after the equal sign and if it is multiplication, it will turn division
Then you open the brackets which makes x-a = t/k
Now you shift "a" after the equal sign which leads to our answer, x= t +ka/k
Answer:
x = [tex]\frac{t+ka}{k}[/tex]
Step-by-step explanation:
k(x - a) = t ← distribute parenthesis on the left side by k )
kx - ka = t ( add ka to both sides )
kx = t + ka ( divide both sides by k )
x = [tex]\frac{t+ka}{k}[/tex]

Question 4:
2x + 3y = 17 -- equation 1
5x + 6y = 32 -- equation 2
(equation 1) * 2
4x + 6y = 34 -- equation 3
(equation 2) - (equation 3)
x = -2 -- equation 4
plug (equation 4)'s value of x into (equation 1)
2(-2) + 3y = 17
3y - 4 = 17
3y = 21
y = 7
Thus the answer is x = -2 and y = 7
Question 5:
The vertex form of a quadrilateral looks like this:
[tex]y = a(x-h)^2 + k[/tex]
a : coefficient of [tex]x^2\\[/tex](h,k): coordinate of the vertex.The x-coordinate of the vertex is equal to '-b/2a'. Where b is the
coefficient of x, so:
[tex]h = -\frac{b}{2a} =-\frac{-8}{2*1} =4[/tex]
There is also another formula to find the y-value of the vertex
coordinate, but the easier way to find it is to plug it into the original
equation:
[tex]k=(4)^2-8(4) + 12= 16 -32 + 12 = -16 + 12 = -4[/tex]
Since we know now that h = 4 and k = -4 and that a = 1, lets plug it into
the original equation.
[tex]y = 1*(x-4)^2 - 4 =(x^2-4)-4[/tex]
Thus the answer is [tex]y = (x-4)^2 -4[/tex]
