On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(−3, 1), B(2, 3), and C(4, −1). A bank employee drives from Branch A to Branch B and then drives halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary.
The minimum total distance the employee may have driven before getting stuck in traffic is
miles.
Answers
Answer:
7.6 miles
Step-by-step explanation:
Given the coordinate points :
A(−3, 1), B(2, 3), and C(4, −1)
Distance (d) between A and B:
x1 = - 3 ; x2 = 2 ; y1 = 1 ; y2 = 3
d = √(x2 - x1)² + (y2 - y1)²
d = √(2 - (-3))² + (3 - 1)²
d = √25 + 4
d = 5.385 miles
BC :
d = √(x2 - x1)² + (y2 - y1)²
d = √(4 - 2)² + (-1 - 3)²
d = √2² + (-4²)
d = √4 + 16
d2 = 4.4721359 miles
(1/2) of d2 = 1/2 * 4.4721359 = 2.236 miles
Total distance = (5.385 + 2.236) miles
Total distance driven before getting stuck in traffic = 7.6 miles

write the linear equation from the given information in slope intercept form (-1,3); slope=-3
Answers
Answer:
y = -3xStep-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x

Answers
Answer:
Step-by-step explanation:
To simplify the expression:
4(3x+2) - 2
The first step is to open the brackets
= 4 * 3x + 4* 2 - 2
= 12x + 8 - 2
= 12x - 6
Factor out the above expression, we get;
= 6(2x - 1)
To factor out the expression:
20b - 16
the factor that can be divided by 20 and 16 without remainder is 4;
So, we have:
= 4(5b - 4)
the graph shows the height of a thrown ball x seconds after it is thrown. based on the situation, are there any constraints on the domain of the function
Answers
Answer:
The time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and is defined.
Given that the graph is showing the height of a thrown ball x seconds after it is thrown.
We must check that the time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.

Express as a product: 1-2cos(2a)
I've been really struggling with this. Please help & explain it.
Answers
Answer:
(2sin a - 1)(2sin a + 1)
Step-by-step explanation:
Here, we want to express what is given as a product
Mathematically;
cos2a = 1-2sin^2A
So we have;
1-2(1-2sin^a)
= 1 - 2 + 4sin^2a
= 4sin^2a - 1
Using the difference of two squares, this is;
(2sin(a) - 1)(2sin a + 1)
