Answer:
If a line is perpendicular to another line, that means that the slope is completely opposite that of the original line. The first thing that we do to the slope is we negate the number which means that if we have a slope of 
our slope because 
in this step. In our case our slope is so in this step it becomes .
Moving onto the second part which is to get the reciprocal of the number which means that if we have 
then we would switch it to 
. In our case our number is so we would make that into a fraction like this 
.
In conclusion, our final slope of the perpendicular line is .

Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.
Answer:
0.95988 (Accuracy of the test )
Step-by-step explanation:
To determine the accuracy of this test we have to list out the given values
Prevalence rate of the disease = 0.3% = 0.003
sensitivity rate of the disease = 92% = 0.92
specificity rate for the test = 96% = 0.96
The accuracy of the test can be found using this equation
Accuracy = sensitivity * prevalence + specificity ( 1 - prevalence )
= 0.92 * 0.003 + 0.96 ( 1 - 0.003 )
= 0.00276 + 0.95712
= 0.95988
Considering the scale as qrst being 3/4 of defg
108x3 = 324
324/4 = 81
Area is 81 cm^2
I’m interested as long as I don’t get caught and in trouble. And you don’t have to pay me anything I like math.
