Example;

To make a the subject from the equation;

ab + c = 1

Take the variable 'c' to the other side

ab = 1 - c

Divide both sides by b, we have;

a = 1 - c/b

Given the expression;

Y = mx + b

Take 'mx' over the equality sign

Y - mx = b

Answer:

1.  -7, -3, square root of 6,  2, 34

Step-by-step explanation:

The expressions evaluated for the given values of x, y, and z, and matched to the values are

1x + y + z       →   -3.8

2(y)(x)           →   -3.2

32x - z          →   13

From the question, we are to evaluate the given expressions for the given values of x, y and z

The given values of x, y, and z are

x = 2/5, y = -4, and z = -0.2

A. 1x + y + z

1(2/5) + (-4) + (-0.2)

2/5 - 4 - 0.2

0.4 - 4 - 0.2

= -3.8

C) 2(y)(x)

2(-4)(2/5)

-8(0.4)

= -3.2

E) 32x - z

32(2/5) - (-0.2)

32(0.4) + 0.2

12.8 + 0.2

= 13

G) 4x + y

4(2/5) + (-4)

4(0.4) - 4

1.6 - 4

= -2.4

Hence, the expressions evaluated for the given values of x, y, and z, and matched to the values are

1x + y + z       →   -3.8

2(y)(x)           →   -3.2

32x - z          →   13

Computing the matrix product in the last condition gives a system of linear equations in the components of [tex]\vec c[/tex],

[tex]\begin{cases} c_1 + b_3c_2 - b_2c_3 = 3 \\ -b_3c_1 + c_2 + c_3 = 1 \\ b_2c_1 - c_2 + c_3 = -1 \end{cases}[/tex]

and is easily solvable to get

[tex]c_1 = \dfrac{6-2b_3}{2+{b_2}^2+{b_3}^2}, c_2 = \dfrac{2+3b_3}{2+{b_2}^2+{b_3}^2}, c_3 = \dfrac{9-3b_3}{2+{b_2}^2+{b_3}^2}[/tex]

or, using the condition [tex]\vec a\cdot\vec b = 3 + b_2 - b_3 = 0[/tex],

[tex]c_1 = -\dfrac{2b_2}{11 + 6b_2 + 2{b_2}^2}, c_2 = \dfrac{11+3b_2}{11+6b_2+2{b_2}^2}, c_3 = -\dfrac{3b_2}{11+6b_2+2{b_2}^2}[/tex]

• (1) is false, since

[tex]\vec a \cdot \vec c = \dfrac{11}{2 + {b_2}^2 + {b_3}^2} \neq 0[/tex]

because [tex]{b_2}^2+{b_3}^2\ge0 \implies 0<\vec a\cdot\vec c\le\frac{11}2[/tex].

• (2) is true.

[tex]\vec b\cdot \vec c = \dfrac{(3 + b_2 - b_3) (2 + 3b_3)}{2 + {b_2}^2 + {b_3}^2} = \dfrac{(\vec a\cdot\vec b)(2+3b_3)}{2+{b_2}^2+{b_3}^2} = 0[/tex]

• (3) is false. The magnitude of [tex]\vec b[/tex] could be smaller than √10.

Since [tex]\vec a\cdot\vec b=0[/tex], we have

[tex]\|\vec b\| = \sqrt{1 + {b_2}^2 + (3+b_2)^2} = \sqrt{10 + 6b_2 + 2{b_2}^2}[/tex]

and

[tex]2{b_2}^2 + 6b_2 = 2\left({b_2}^2 + 3b_2 + \dfrac94\right) - \dfrac{18}4 = 2\left(b_2 + \dfrac32\right)^2 - \dfrac92 \ge - \dfrac92[/tex]

which is to say, [tex]\|\vec b\| \ge \sqrt{10-\frac92} = \sqrt{\frac{11}2}[/tex].

• (4) is true.

We have

[tex]\|\vec c\| = \dfrac{\sqrt{11} \sqrt{11 - 6b_3 + 2{b_3}^2}}{2 + {b_2}^2 + {b_3}^2}[/tex]

In terms of [tex]b_2[/tex] alone,

[tex]\|\vec c\| = \dfrac{\sqrt{11}\sqrt{11 + 6b_2 + 2{b_2}^2}}{11+6b_2+2{b_2}^2} = \dfrac{\sqrt{11}}{\sqrt{11+6b_2+2{b_2}^2}}[/tex]

Now,

[tex]11 + 6b_2 + 2{b_2}^2 = 2\left(b_2+\dfrac32\right)^2 + \dfrac{13}2 \ge \dfrac{13}2[/tex]

which means

[tex]\|\vec c\| \le \dfrac{\sqrt{11}}{\sqrt{11 + \frac{13}2}} \le \sqrt{11}[/tex]

Answer:

Step-by-step explanation:

A)   We can find half of the width of the surface by applying pythagorean theorem on the right angled triangle formed by three points which are the center of the circle, the point on the circle where the the endpoints of the width and the radius meet, and the midpoint of the width.

let radius=r, width=w

[tex]r^2=(w/2)^2+(3.4-2.1)^2\\[/tex], since the distance between the origin and the midpoint of the width is 3.4m-2.1m.

[tex]-(w/2)^2=(3.4-2.1)^2-r^2, r=2.1\\-(w/2)^2=(1.3)^2-(2.1)^2\\-(w/2)^2=1.69-4.41\\-(w/2)^2=-2.72\\w/2=\sqrt{2.72}\\w=2*\sqrt{2.72}\\w=3.3 meter[/tex]

B) we can find the other depth of oil which can give the same surface area of oil if the now empty part of the cylinder is filled with oil and the now filled part of the cylinder is empty, so the other possible depth for the same surface area of oil is the diameter of the circle minus 3.4 meters:

diameter=4.2 meter, 4.2 meter-3.4 meter:

0.8 meter depth

a. The width (x) of the oil surface is approximately 5.348 meters.

b. Another depth of oil that would give the same surface width (x ≈ 5.348 meters) is approximately 3.402417 meters.

a) Here, we have to calculate the width (x) of the oil surface, we need to find the length of the chord of the circular cross-section at the top of the oil tank.

We can use the formula for the length of a chord in a circle when the depth and radius are known.

Given that the radius (r) of the circular cross-section is 2.1 meters and the depth (d) of the oil is 3.4 meters, the width (x) can be calculated as follows:

x = 2 * √(r * d)

x = 2 * √(2.1 * 3.4)

x = 2 * √(7.14)

x ≈ 2 * 2.674

x ≈ 5.348 meters

So, the width (x) of the oil surface is approximately 5.348 meters.

b) Now, let's find the other depth of oil that would give the same surface width (x = 5.348 meters).

We can rearrange the formula to solve for the depth (d):

x = 2 * √(r * d)

Divide both sides by 2:

x/2 = √(r * d)

Square both sides:

(x/2)² = r * d

Now, plug in the given values (x = 5.348 meters and r = 2.1 meters) and solve for d:

(5.348/2)² = 2.1 * d

2.674² = 2.1 * d

7.145076 = 2.1 * d

Divide by 2.1:

d ≈ 7.145076 / 2.1

d ≈ 3.402417

So, another depth of oil that would give the same surface width (x ≈ 5.348 meters) is approximately 3.402417 meters.
