Answer:
The coordinates of the point one half the distance is (6,1)
Step-by-step explanation:
Here we want to calculate the coordinates one half of the line segment.
This in another way simply means the coordinates of the midpoint of that segment;
Mathematically;
we proceed with this using the midpoint formula
(x,y) = (x1 + x2)/2, (y1 + y2)/2
From the question (x1,y1) = (5,-6) while (x2,y2) = (7,8)
let’s say
(x,y) = (5 + 7)/2 , (-6 + 8)/2
(x,y) = 12/2, 2/2
(x,y) = (6,1)
If you have two sides, you only need two. Otherwise it’s 3 parts
The total cost function is the sum of the two given functions, and this is equal to:
c(t) = 190 + 70*t
<h3>
How to find the linear function for the total cost?</h3>
We know that:
- The plumber charges p(t) = 115 + 25*t
- The electrician charges e(t) = 55*t + 75.
If she hires both of them for the same time t, then the total cost function will be given by the sum of the two above functions, we will get:
c(t) = p(t) + e(t)
c(t) = (115 + 25*t) + (55*t + 75)
c(t) = (115 + 75) + (55*t + 25*t)
c(t) = 190 + 70*t

Answer:
Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it? The two events are independent, so you need to find the product of their probabilities: 0.9 × 0.75 = 0.675.
