The value of the variables based on the equation is illustrated below.

<h3>How to calculate the variables?</h3>

Based on the information given, it should be noted that an equation simply means a formula that can be used to express the equality of two expressions.

1x - 1 - 4.2x = 5.3

Collect the like terms

1x - 4.2x = 5.3 + 1

-3.2x = 6.3

x = -1.969

7/8m - 4/7 - 5/6m = - 3/4

Collect the like terms

0.875m - 0.5714 - 0.833 = -0.75

0.875m = -0.75 + 0.5714 + 0.833

0.875m = 0.6544

m = 0.6544/0.875

m = 0.748

4.3v + 10.75 - 4v = 8.11

Collect the like terms

4.3v - 4v = 8.11 - 10.75

0.3v = -2.64

v = -2.64/0.3

v = -8.8

9/7 + 9/7x - 6/7x = 0

Collect the like terms

9/7x - 6/7x = 0 - 9/7

3/7x = -9/7

x = -9/7 × 7/3

x = -3

6.9u - 2 - 3.2u - 10 = 2.8

Collect the like terms

6.9u - 3.2u = 2.8 + 12

3.7u = 14.8

u = 14.8/3.7

u = 4

8/5 = - 4a + 7/5 - 2/3a

Collect the like terms

4a + 2/3a = 7/5 - 8/5

4 2/3a = -1/5

14/3a = -1/5

a = -1/5 × 3/14

a = -3/70

8p + 6 - 4p = -14

Collect like terms

8p - 4p = -14 - 6

4p = -20

p = -20/4

p = -5

7 - (5t - 13) = -25

Collect like terms

-5t = -25 - 7 - 13

-5t = -45

t = -45/-5

t = 9

A solid lies between planes perpendicular to the​ x-axis at x = 0 and x = 17. The​ cross-sections perpendicular to the axis on t
arlik [135]

Answer:

Therefore, we get that the volume of the solid is V=8/3  · 17^{3/2}.

Step-by-step explanation:

From exercise we have that

0 ≤ x ≤ 17

 y = -2 √x  and  y = 2 √x.

We calculate the volume of the solid, we get:

\int\limits^17_0 \int\limits^{2 √x}_{-2 √x} {1} \, dy \, dx=

=\int\limits^17_0 [y]\limits^{2 √x}_{-2 √x} \, dx

=\int\limits^17_0 {(2 √x+2 √x)} \, dx

=4\int\limits^17_0 {√x} \, dx

=4 · 2/3 [x]\limits^17_0

=8/3  · 17^{3/2}

Therefore, we get that the volume of the solid is V=8/3  · 17^{3/2}.
