Answer:
This may be a bug in the Graph, lets sole it
(y-5)^2+(x+5)^2=4.1^2
(y-5)^2+(-9.1+5)^2=4.1^2
After Solving, Y=5
and you may use other graphing calculator such as GeoGebra, Mathwy, Photomath, it shows the answer Correctly
Answer:
Step-by-step explanation:
I am not exactly sure why it is undefined, but in my thought process below, I have noticed a trend, and it might help spark some thoughts.
(y-5)² + (x+5)² = r²
r = 4.1
x = -9.1
y = ?
If we try plugging in the known values to solve for y, then...
(y-5)² + (-9.1+5)² = 4.1²
(y-5)² + 16.81 = 16.81
(y-5)² = 0
y-5 = √0
y = 5
Now solving the equation does show that y exists, so maybe it's a domain/range problem. So let's find the domain and range.
The standard form is (x-a)² + (y-b)² = r², so since we have (y-5)² + (x+5)² = r², our (a is -5) and (b is 5) (and r is 4.1)
The domain of a circle is a-r ≤ x ≤ a+r, which gives (-5)-4.1 ≤ x ≤ (-5)+4.1
So our domain is -9.1 ≤ x ≤ -0.9
The range of a circle is b-r ≤ y ≤ b+r, which gives (5)-4.1 ≤ y ≤ (5)+4.1
So our range is 0.9 ≤ y ≤ 9.1
When x = -9.1, it is within the domain.
When y = 5, it is also within the domain.
Which means that the y value should exists.
BUT...
Here's a trend that I have noticed on desmos...
When (y-5)² + (x+5)² = r² and r = 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+5)² = r² and r = - 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+4)² = r² and r = 4.1, y is undefined at the domain boundaries of -8.1 and -0.1
When (y-4)² + (x+5)² = r² and r = 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+6)² = r² and r = 4.1, y is undefined at the domain boundaries of -10.1 and -1.9
When (y-6)² + (x+5)² = r² and r = 4.1, y is defined (y=6) at the domain boundaries of -9.1 and -0.9
When (y-6)² + (x+6)² = r² and r = 4.1, y is defined (y=6) at the domain boundaries of -10.1 and -1.9
When (y-6)² + (x+5)² = r² and r = 8.3, y is undefined at the domain boundaries of -13.3 and 3.3
When (y-6)² + (x+6)² = r² and r = 8.3, y is undefined at the domain boundaries of -14.3 and 2.3
I do not understand the trend despite of spending last night and today thinking about it. But Hope it helps. (If you saw me answering yesterday night, yea that's me, I ended up deleting it cuz I can't think it through, but then I thought that maybe it could help spark your thoughts, so here it is)
A science class has 5 girls and 7 boys in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.
We have a total of 10 boys & 8 Girls, then the sample space consist of 18 elements.
P(selecting 1 boy) = (total number of boys/by 18) = P(boy)=10/18=5/9
Use the intermediate value theorem to find the value of c such that f(c) = M. f(x) = x^2 - x + 1 text( on ) [1,8]; M = 21 c =
Answer:
[tex]c = 5[/tex]
Step-by-step explanation:
Given
[tex]f(c) = M[/tex]
[tex]f(x) = x^2 - x + 1[/tex]
[tex]Interval: [1,8][/tex]
[tex]M = 21[/tex]
Required
Find c using Intermediate Value theorem
First, check if the value of M is within the given range:
[tex]f(x) = x^2 - x + 1[/tex]
[tex]f(1) = 1^2 - 1 + 1[/tex]
[tex]f(1) = 1[/tex]
[tex]f(x) = 8^2 - 8 + 1[/tex]
[tex]f(x) = 57[/tex]
[tex]1 \le M \le 57[/tex]
[tex]1 \le 21 \le 57[/tex]
M is within range.
Solving further:
We have:
[tex]f(c) = f(x) = M[/tex]
[tex]f(x) = 21[/tex]
Substitute 21 for f(x) in [tex]f(x) = x^2 - x + 1[/tex]
[tex]21 = x^2 - x + 1[/tex]
Express as quadratic function
[tex]x^2 - x + 1 - 21 = 0[/tex]
[tex]x^2 - x - 20 = 0[/tex]
Expand
[tex]x^2 + 4x - 5x - 20[/tex]
[tex]x(x+4)-5(x+4)=0[/tex]
[tex](x - 5)(x+4) = 0[/tex]
[tex]x - 5 = 0[/tex] or [tex]x + 4= 0[/tex]
[tex]x = 5[/tex] or [tex]x = -4[/tex]
The value of [tex]x = -4[/tex] is outside the [tex]Interval: [1,8][/tex]
So:
[tex]x = 5[/tex]
[tex]f(c) = f(x) = M[/tex]
[tex]f(c) = f(5) = 21[/tex]
By comparison:
[tex]c = 5[/tex]

Jill drove her car for 7 days across the country. She travelled 525 miles. If she continues this pace, how many miles will she have driven after 12 days?
Answer:
900 miles
Step-by-step explanation:
In 7 days she travels 525 miles.
So, in 1 day she travels: 525 ÷ 7 = 75miles
In 12 days she will have driven : 75 × 12 = 900 miles
Step-by-step explanation:
of at 7days Jill drove 525 miles
then she would drive x Miles in 12 days
7d = 525 miles
12 d = (12 ×525)/7
900 miles

Answer for the question:
It is B.
If AC = 14, what is the measure of AD? Round your answer to the nearest hundredth.
Part A
Answer: Choice D) [tex]\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}[/tex]
-----------------------------------------------
Explanation:
Let E be the intersection point of the diagonals. For any parallelogram, the diagonals bisect each other. This means that AE = EC = 2n+5 and it also means EB = DE = 4n-3
Focus on triangle AED. This triangle is a right triangle with angle AED as a 90 degree angle (any rhombus has its diagonals that are perpendicular to one another). The legs of this triangle are AE = 2n+5 and ED = 4n-3
Apply the pythagorean theorem to find hypotenuse AD
[tex](\text{leg1})^2+(\text{leg2})^2 = (\text{hypotenuse})^2\\\\(\text{AE})^2+(\text{ED})^2 = (\text{AD})^2\\\\(\text{AD})^2 = (\text{AE})^2+(\text{ED})^2\\\\\text{AD} = \sqrt{(\text{AE})^2+(\text{ED})^2}\\\\\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}\\\\[/tex]
This points to choice D as the final answer.
===========================================================
Part B
Answer: 7.07-----------------------------------------------
Explanation:
If AC = 14, then half of this is AE = 7. The diagonals bisect each other, so they cut each other in half with E at the midpoint.
Since AE = 2n+5, we can solve for n like so
2n+5 = 7
2n = 7-5
2n = 2
n = 2/2
n = 1
Then we can find the length of AD
[tex]\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}\\\\\text{AD} = \sqrt{(2*1+5)^2+(4*1-3)^2}\\\\\text{AD} = \sqrt{(2+5)^2+(4-3)^2}\\\\\text{AD} = \sqrt{7^2+1^2}\\\\\text{AD} = \sqrt{49+1}\\\\\text{AD} = \sqrt{50}\\\\\text{AD} \approx 7.0710678\\\\\text{AD} \approx 7.07\\\\[/tex]
Segment AD is roughly 7.07 units long. The other external sides of the rhombus (AB, BC and CD) are also this length because the four sides of any rhombus are the same length.

9514 1404 393
Answer:
a) -13
b) -22
Step-by-step explanation:
It can be convenient to compute the function values first:
f(1) = 1² -14·1 = -13
g(1) = 1 +8 = 9
Then the compositions are ...
(a) (f+g)(1) = f(1) +g(1) = -13 +9 = -4
(b) (f-g)(1) = f(1) -g(1) = -13 -9 = -22
Please solve this thank you :)

Elena drank 5 bottles of water over 7 volleyball practices. How much water did Elena drink each practice if she drank the same amount each time?
Please have good explanation
Answer:
Step-by-step explanation:
If you would like to know how much water did Elena drink each practice if she drank the same amount each time, you can calculate this using the following steps:
5 bottles of water ... 7 practices
x bottles of water = ? ... 1 practice
5 * 1 = 7 * x
5 = 7 * x /7
x = 5/7 bottle of water
The correct result would be 5/7 bottle of water.

Answer: x=15
Step-by-step explanation:
Since these are supplementary angles, we know that if we add them together we would get 180 deg. so....
(7x-10)+ (6x-5)=180
Kay so now we can combine like terms.
13x-15=180
Now we can add 15 to both sides.
13x=195
Finally Divide 13 on both sides.
X would then now equal 15.
