PiCAT Practice Test Part 2
This flashcard set includes key PiCAT concepts such as friction reduction and plant growth processes. It reinforces understanding of how ball bearings reduce friction and how germination marks the beginning of a seed’s development into a plant.
What Is 8b - ab + 7 subtracted from 3a - 9ab + b?
-4a - 8ab -7b
Key Terms
What Is 8b - ab + 7 subtracted from 3a - 9ab + b?
-4a - 8ab -7b
Graphs of the following equations are straight lines EXCEPT
A 3x + 2y = 8
B y = x / 2 - 5
C x = 4y
D y = x ^ 2 + 3
y=X^2+3
What is the area of a triangle with a base of 8 feet and a height of 4 feet ?
16 square feet
In the formula , if then C = 35 F =?
95
C = 5/9(F - 32)
C = 35
35 = 5/9(F-32)
35 * 9/5 = (F-32)
(F-32) = 63
F = 63 + 32 = 95
The Reciprocal of 7 is
1/7
In making permanent electronic connections use
soldering iron
