Answer:
x^2 - 3x - 40
Step-by-step explanation:
x = 8 and x = -5
x - 8 = 0 and x + 5 = 0
(x - 8)(x + 5)
x^2 + 5x - 8x - 40
x^2 - 3x - 40
Answer: x^2 - 3x - 40
Answer:
0.0053
Step-by-step explanation:
Look at the 2 significant figures which are non-zero digits.
The two figures are 5 and 4, the digit after 4 is 3, which is lower than 5, so we don’t have to add +1 to the 4.
the SAS similarity theorem
4.70, all the others can be simplified to 4.07 by taking away the zeroes after the 7 because they are not significant, The one before the 7 stays because it is significant as it is holding the tenths place value.
Answer:
1130.4 mm
Step-by-step explanation:
Given,
Radius ( r ) = 180 mm
To find : Circumference of the pulley ( C ) = ?
Formula : -
C = 2πr
Note : -
Value of π is 3.14
C = 2 x 3.14 x 180
C = 1130.4 mm
