Step-by-step explanation:
the equation of the circle centered at (-3, – 10)
=> (x+3)²+(y+10)²=2²
<=> x²+6x+9+y²+20y+100=4
x²+y²+6x+20y+105=0
Let's see
[tex]\\ \rm\dashrightarrow (x-h)^2+(y-k)^2=r^2[/tex]
(h,k)=(-3,-10)[tex]\\ \rm\dashrightarrow (x+3)^2+(y+10)^2=2^2[/tex]
[tex]\\ \rm\dashrightarrow (x+3)^2+(y+10)^2=4[/tex]
[tex]\\ \rm\dashrightarrow x^2+y^2+6x+20y+105=0[/tex]
What is the slope of the line that contains the points (14,-2) and (3,-2)
Answer:
0
Step-by-step explanation:
We can use the slope formula since we have two points
m = ( y2-y1)/(x2-x1)
= ( -2- -2)/(3-14)
= ( -2+2)/(3-14)
= 0/-11
= 0
Answer:
0 is the slope of the line that contains the points (14,-2) and (3,-2)
Step-by-step explanation:
We have two points which are ( 14 , -2) and ( 3, -2).To find , the slope is the slope of the line that contains the points (14 , -2)and (3, -2)
we using slope formula which is
m = ( y ² - y ¹ ) / ( x ² - x ¹)Where,
m , is the slope
( y ² - y ¹ ) = ( 14 , - 2)
( x ² - x ¹) = (3, -2 )
Substitute the values into the formula
m = (( -2 )- ( -2 ) ) / (3 - 14 )
m= ( -2 + 2 ) / ( 11)
m = 0 / 11
m = 0
Therefore , 0 is the slope of the line that contains the points (14,-2) and (3,-2)

A straight road crosses two parallel railway tracks. The angle between the road and the
The first track is 95°. What is the angle between the road and the second track? Why?
[Hint: Draw a pair of parallel lines and a transversal]
=======================================================
Explanation:
I recommend drawing it out to see what's going on. See the drawing below.
In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees.
Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.
sin 24 degrees = 12.1/ x
Answer:
29.749
Step-by-step explanation:
cross multiply sin with x, and then divide sin and divide 12.1 by sin24

There are 3 buses in the park. The first
bus takes 2 hours to make a round trip,
the next bus takes 4 hours and the
third bus takes 5 hours. If they all
leave the park at the same time, how
many hours later will they all arrive
back in the park, at the same time?
Answer:
20 hours later.
Step-by-step explanation:
If all three buses leave at the same time, they will arrive back in the park in 20 hours. If we want them to arrive at the exact same time, we need to find the least common multiple of all the numbers because the time it takes to get back into the park are different and without using least common multiple they would all arrive at different times. So, the least common multiple is 20 becuase they all have 20 as a multiple. In 20 hours all of the buses will arive back in the park at the same time.
Hope this helps

What is the rule for the reflection ?
Answer:
This idea of reflection correlating with a mirror image is similar in math.
This complete guide to reflecting over the x axis and reflecting over the y axis will provide a step-by-step tutorial on how to perform these translations.
First, let’s start with a reflection geometry definition
Math Definition: Reflection Over the X Axis
A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image. In this case, the x axis would be called the axis of reflection.
Math Definition: Reflection Over the Y Axis
A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image. In this case, theY axis would be called the axis of reflection.
What is the rule for a reflection across the X axis?
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

You start driving west for 9 miles, turn right, and drive north for another 6 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Answer:
10.8 mi
Step-by-step explanation:
Picture a right triangle with legs 9 mi and 6 mi. Applying the Pythagorean Theorem (d² = a² + b²), we get:
(9 mi)² + (6 mi)² = 117 mi²
This is the square of the hypotenuse (the desired distance).
Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d
The desired straight line distance traveled is 10.8 mi
What is an equivalent equation solved for h? h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b ÷ r h = h equals left-parenthesis StartFraction p Over 0.7 EndFraction right-parenthesis divided by r minus b.÷ r – b h = h equals StartFraction p minus b Over 0.7 EndFraction divided by r. ÷ r
Answer:
h = (p/0.7 - b) ÷ r
Step-by-step explanation:
Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b. What is an equivalent equation solved for h?
Given:
p = 0.7(rh + b)
Divide both sides by 0.7
p / 0.7 = rh + b
p/0.7 - b = rh
p/0.7 - b ÷ r = h
h = (p/0.7 - b) ÷ r

in a class test (+ 5) marks are given for every correct answer and (-3) marks are given for every incorrect answer.
a) Anu gets 8 correct answer and 12 incorrect answers what is her score?
b) Sam answered all the questions and scored 28 marks though he got 11 correct answers.
How many incorrect answers had he attempted?
● Please answer my question and I do not need any links
Answer:
a. 4 marks b. 9 questions
Step-by-step explanation:
a) Anu gets 8 correct answer and 12 incorrect answers what is her score?
Since Anu got 8 correct answer and 12 incorrect answers, and + 5 marks is given for every correct answer and (-3) marks are given for every incorrect answer, the total score for correct answers is number of correct answer × marks for correct answer = 8 × (+ 5) = 40.
Also, the total score for incorrect answers is number of incorrect answer × marks for incorrect answer = 12 × (- 3) = -36.
Anu's total score = total score for correct answers + total score for incorrect answers = 40 + (-36) = 40 - 36 = 4 marks.
So, Anu scored 4 marks.
b) Sam answered all the questions and scored 28 marks though he got 11 correct answers. How many incorrect answers had he attempted?
Let x be the number of incorrect answers. Since the marks for incorrect answers is -3, then his total score for incorrect answers is -3x.
Since Sam got 11 correct answers and is given + 5 marks for each correct answer, then his total score for correct answers is 11 × (+5) = +55.
Since he gets a total of 28 marks, we have that total score for incorrect answer + total score for correct answer = 28.
So, -3x + 55 = 28
Solving for x, we have
-3x = 28 - 55
-3x = -27
x = -27/-3
x = 9
Since x = 9, Sam attempted 9 incorrect questions.
.
Answer:
He or she attempted 9 incorrect answers

what is the gradient for the table x y
-6 -10
-3 -8
3 -4
6 -2
Solution :
Let, equation of line is y = mx + c .
Here, m is the slope( or gradient ) of the line and c is the y-intercept .
Putting point ( -6, -10 ) in above equation, we get :
-10 = -6m + c ...1)
Also, putting point ( -3, -8 ) in above equation, we get :
-8 = -3m + c ...2)
Solving equation, 1) and 2) we get :
[tex]m = \dfrac{2}{3}\ and \ y = - 6[/tex]
Therefore, the gradient for the given x-y table is [tex]\dfrac{2}{3}[/tex] .
