Answer:5.8
Step-by-step explanation:
Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
=
![\left [\frac{r_{plunger}}{r_{piston}}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%7D%7Br_%7Bpiston%7D%7D%5Cright%20%5D)
=![\left [ \frac{2118}{63}\right ]^{0.5}](https://tex.z-dn.net/?f=%5Cleft%20%5B%20%5Cfrac%7B2118%7D%7B63%7D%5Cright%20%5D%5E%7B0.5%7D)
=5.798
Excluded values are any values of x that make the denominator equal zero. In this case, -2 and 2 are excluded values.
Answer:
B
Step-by-step explanation:
well, the sequence are in the form
a1 = first term = 45
you can plug 1 to any of the option
and ended with B the only function that satisfies what we need
Answer:
A
Step-by-step explanation:
I believe it is A because for perpendicular lines the slope must be the reciprocal and have the opposite sign. The y-intercept 2 matches the coordinates (-2, 2). The second number, 2, is the y coordinate.
Answer:
A. the median of the lower half of a data set ordered from least to greatest
Step-by-step explanation:
The first quartile can best described as the median of the lower half of a data set ordered from least to greatest.
Let us explain this with an example, say you're given a set of numbers: {1, 2, 5, 8, 9, 12, 15, 16, 20, 23, 25, 28, 32, 36, 42}. The median for the set is 16, the first quartile is going to be the median of the first half which is 8.
