The coordinates of B is (-2, 3).

In geometry, translation is the movement of a point or shape from one position to another.

Here, The translation from ΔABC to ΔA'B'C' is (x, y) → (x + a, y + b)

Now, given coordinate

A ≡ (5, 1)      ⇒       A' ≡ (6, -2)

                             A' ≡ (1+5, 1 - 3)

                      On comparing this coordinate with translation coordinate

                       (x + a, y + b), we get

                          a = 1 and b = -3

Now translation coordinates is (x + 1, y - 3),

Now, Another coordinate;

B' ≡ (-1, 0)                   and the coordinate of B ≡ (x, y)

B' ≡ (-2+1, 3-3)

On comparing this coordinate with translation coordinate (x + 1, y - 3), we get

x = -2 and y = 3

Thus, the coordinates of B is (-2, 3).

Answer:

c. a[b(b + 6)+7(a²-2)]

Step-by-step explanation:

look at the pic

The equivalent expression of the expression ab² + 6ab + 7a³ - 14a is

C. a [b (b + 6) + 7 (a² - 2)]

Option C is the correct answer.

We have,

To find the expression that is equivalent to ab² + 6ab + 7a³ - 14a, we can factor out common terms from the given expression.

The common terms in the expression are "a" and "(b + 7)".

Step 1:

Factor out "a" from the expression:

ab² + 6ab + 7a³ - 14a = a(b² + 6b + 7a² - 14)

Step 2:

Factor the quadratic expression inside the parenthesis:

b² + 6b can be factored as b(b + 6)

7a² - 14 can be factored as 7(a² - 2)

Step 3:

Putting it all together, the equivalent expression is:

a [b (b + 6) + 7 (a² - 2)]

Now let's check which option matches this expression:

a. (b + 7)(b + 6)(a² - 2) - Not equivalent

b. b(b + 6) + 7(a^2 - 2) - Not equivalent

c. a[b(b + 6) + 7(a² - 2)] - Equivalent

d. a[(b + 6)(b + 7a² - 14)] -Not equivalent

Thus,

The equivalent expression is

C. a [b (b + 6) + 7 (a² - 2)]

Answer:

[tex]\huge\boxed{\sf y = -2x - 3}[/tex]

Step-by-step explanation:

m = -2

y = mx + c

(x,y) = (-5,7)

So, x = -5, y = 7

To find c, Put the values of x, y and m in the slope-intercept form.

7 = (-2)(-5) + c

7 = 10 + c

7 - 10 = c

-3 = c

c = -3

Now, put the values of m and c in the slope intercept form.

y = -2x - 3

Answer:

slope = -2

Step-by-step explanation:

The general structure of an equation in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. Since the given equation is not in the exact slope-intercept form, we need to rearrange it to identify the slope.

y + 2x = 5                         <----- Given equation

y = -2x + 5                       <----- Subtract 2x from both sides

Now, we can see that in the "m" position, there is a value of -2. This makes the slope = -2.

The dimensions of the circular cylinder of maximum volume inscribed in  sphere is r = 20.4 cm , h = 28.86 cm.

A sphere is a three dimensional round shaped figure , It has no vertices and the distance form the centre to any point on the sphere is same.

It is given that

A right circular cylinder is inscribed in a sphere

The circular cylinder has the maximum volume

Radius of the sphere is 25 cm.

Dimensions of the cylinder = ?

As it is a right cylinder.

The Pythagoras theorem can be applied

r² + (h/2)² = 25²

r² = 625 - h²/4

volume of the cylinder

=  πh(625 - h²/4)

= π(625 h - h³/4)

As the volume is maximum ,

so the derivative of the expression = 0

π(625 - 3h²/4) = 0

so h =  50 /√ 3

so r² = 625 - 2500 / (3 *4 )

r = 20.4 cm

h = 28.86 cm

Therefore the dimensions of the circular cylinder of maximum volume inscribed in a sphere is r = 20.4 cm , h = 28.86 cm.

The amount or the strength of force is called its magnitude.

Step-by-step explanation:

The amount or the strength of force is named magnitude.

Force is that the push or pull on an object with mass that causes it to alter its velocity. Force is an external agent capable of adjusting the state of rest or motion of a selected body. it's a magnitude and a direction.

The term which is true is magnitude. The magnitude of a force is expressed within the SI unit of force called Newton. 1 Newton is that the force which might make an object of 1 kilogram mass to  at a speed of 1 meter per second. Magnitude is essentially the most extent of size and also the direction of an object. Magnitude is employed as a typical think about vector and scalar quantities.

Answer:

[tex]1024x^{40}[/tex]

Step-by-step explanation:

So the first step is to add like terms since you can simplify the numerator by adding the two values sine they have the same variable and degree.

Add like terms:

[tex][\frac{8x^9}{2x}]^5[/tex]

Divide by 2x (divide coefficient by 2, subtract coefficient degrees)

[tex][4x^8]^5[/tex]

Multiply exponents and raise 4 to the power of 5

[tex]1024x^{40}[/tex]

The reason you multiply exponents is because you can think about it like this:

(4 * x * x * x * x * x * x * x * x) (this has one 4 and 8 x's because x is raised to the power of 8. Now if you do that 5 times which is what the exponent is doing you're going to have 40 x's and 8 4's. So it's essentially

(4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x). If you group like terms you'll get (4 * 4 * 4 * 4 * 4) *  (x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x). Which simplifies to 4^5 * x ^ (8 * 5) which further simplifies to the answer 1024x^40

Answer:

1024x^40

Step-by-step explanation:

Apply exponent rule: (a/b)^c = a^c / b^c = (5x^9 + 3x^9)^5 / (2x)^5

Simplify:

(5x^9 + 3x^9)^5: 32768x^45

= 32768x^45 / (2x)^5

Simplify:

(2x)^5: 32x^5

= 32768x^45 / 32x^5

Divide the numbers: 32768 / 32 = 1024

= 1024x^45 / x^5

Apply exponent rule: x^a / x^b = x^a - b

x^45 / x^5 = x^45 - 5

= 1024x^45 - 5

Subtract the numbers: 45 - 5 = 40

= 1024x^40

Answer:

y = 20°

x = 35°

Explanation:

Equation's:

   1) 2y + x + 105° = 180°

   2) 3x + x + 2y = 180°

Make y subject in equation 2

3x + x + 2y = 180

4x + 2y = 180

2y = 180 - 4x

y = 90 - 2x

Insert this into equation 1

2(90 - 2x) + x + 105° = 180°

180 - 4x + x + 105 = 180

-3x = -105

x = 35°

Find value of y

y = 90 - 2x

y = 90 - 2(35)

y = 20°
