Find the equation of the line that passes points
A(1,7)B(-3,-1)
Answer:
y = 2x + 5
Step-by-step explanation:
Here we have the two points as (x1=1, y1=7) and (x2 = -3, y2 = -1)
Slope of this line = (y2-y1)/(x2-x1) = (-1 -7)/(-3 - 1) = 8/4 = 2
Using slope intercept form of y = mx + c
we get y = 2 x + c
Substituing the coordinates (1,7) in this equation gives us
7 = 2.1 + c or c =5
hence y = 2x + 5
Check
if x = -3 then y = (-2)(-3) + 5 = -6 + 5 = -1 which satisfies the coordinates for the second point

What is the Area of the Sector?In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.
The formula for Area of a sector is given as;
θ/360 * πr²
where;
θ is the central angle of the sector
r is radius
Now, looking at the given options we can say that the only one that represents the area of the sector is;
A = n/360 * πr²
where n is the central angle of the sector
Given data ,
Let the arc of the sector be represented as YOR
Now , the center of the circle is Q
The angle subtended by the minor arc of the circle = 150°
So , the remaining angle = 360° - 150° = 210°
And , the angle subtended by the major arc = 210°
So , the arc YOR is the major arc of the circle
Hence , the major arc is YOR

A furniture shop produces two types of custom made chairs. If the price of one type of chair is three times the price of the other, and the total price for both is $15365, what is the price of other chair?
Answer:
The price of other chair is $3841.25
Step-by-step explanation:
Step 1: Write equations.
First equation: The price of one type of chair is three times the price of the other.
Let x be the price of one type of chair and y the price of the other type of chair.
[tex]x = 3y[/tex]
Second equation: The total price for both is $15365
[tex]x + y = 15365[/tex]
Step 2: Solve the system of equations.
1) [tex]x = 3y[/tex]
2) [tex]x + y = 15365[/tex]
Substitute x in the second equation with x from first.
[tex]x + y = 15365\\(3y) + y = 15365[/tex]
Now solve for y (y is the price of the other chair).
[tex]4y = 15365\\y = \frac{15365}{4}\\y = \$3841.25[/tex]

Answer:
(-2, -11)
(0, -1)
(2, 9)
(4, 19)
Step-by-step explanation:
when x = -2:
⇒ y = 5(-2) - 1
⇒ y = -10 - 1
⇒ y = -11
when x = 0:
⇒ y = 5(0) - 1
⇒ y = 0 - 1
⇒ y = -1
when x = 2:
⇒ y = 5(2) - 1
⇒ y = 10 - 1
⇒ y = 9
when x = 4:
⇒ y = 5(4) - 1
⇒ y = 20 - 1
⇒ y = 19

The points appear to be on a straight line; this represents a linear associationOne point is relatively far from other points on the plot; this means the graph has an outlierAs the points on the x-axis increases, the points on the y-axis increases; this means a positive associationThe above highlights mean that (a), and (d) are true
Since the graph is a linear association, then it can be used to model hourly rates
This means that (e) is true

Answer:
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232Step-by-step explanation:The Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:Mean = 190Standard deviation = 14Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?148 = 190 - 3*14So 148 is 3 standard deviations below the mean.232 = 190 + 3*14So 232 is 3 standard deviations above the meanBy the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232
Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak. Hunger strikes and she wants to make it to Kono's for lunch; see picture. Brooke can paddle 7 mph and walk 14 mp
If she paddles along a straight line course to the shore, find an expression that computes the total time to reach lunch in terms of the location where Brooke beaches her kayak (so x = distance from A to where she lands). Be sure you remember the formula that relates Distance, Rate and Time. You're being asked for Time here
If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.
Hunger strikes and she wants to make it to Kono's for lunch; see picture.
Brooke can paddle at 7 mph and walk at 14 mph.
Distance from Brooke to shore will be
→ √(5² + x²)
Then the time will be
[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]
Then the distance from shore to Kono's will be
→ 6 - x
Then the time will be
t₂ = (6 - x) / 4
Then the total time will be
t = t₁ + t₂
Then we have
[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]
t = 1/4[2√(5² + x²) + 6 - x]
If she paddles directly to point A will be
t = 1/4[2√(5² + 0²) + 6 - 0]
t = 1/4 (10 + 6)
t = 16 /4
t = 4 hr
If she paddles directly to Kono's, then we have x = 6. Then the time will be
t = 1/4[2√(5² + 6²) + 6 - 6]
t = 1/4[2√61]
t = 3.9 hr

The coordinates of the point B are given as (2, - 4)
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Under a reflection in the y- axis
A point (x, y) → (- x, y), hence
A(- 2, - 4) → B(2, - 4)
