3. Write y = x2 - 4x + 6 in vertex form.

A. y = (x - 2)2 + 2

B. y = (x + 2)2 - 2

C. y = (x + 2)2 - 4

D. y = (x - 2)2 + 4

Answers

Answer 1

Answer:

A.

[tex]y = (x - 2 {)}^{2} + 2[/tex]

Step-by-step explanation:

[tex]y = {x}^{2} - 4x + 6[/tex]

[tex] = y + 4 = {x}^{2} - 4x + 4 + 6[/tex]

[tex] = y + 4 = (x - 2 {)}^{2} + 6[/tex]

[tex] = y = (x - 2 {)}^{2} + 6 - 4[/tex]

[tex] = y = (x - 2 {)}^{2} + 2[/tex]

mary has 17 m of rope. She wishes to cut it in three pieces so that she has 3 m more than amanda, and amanda has 2 m less than Sarah.

Answers

Answer:

Length of Sarah rope    = 6 m

Length of Amanda's rope  = 4 m

Length of Mary's rope  = 7 m

Step-by-step explanation:

Let the length of Sarah rope = x

Length of Amanda's rope= x - 2

Length of Mary's rope = (x - 2 ) + 3 = x - 2 + 3 = x + 1

Length of rope = 17 m

x + x - 2 + x + 1 = 17

Combine like terms

x + x + x - 2 + 1 = 17

       3x  - 1 = 17

Add 1 to both sides

3x = 17 + 1

3x = 18

Divide both sides by 3

x = 18/3

x = 6

Length of Sarah rope = x  = 6 m

Length of Amanda's rope= x - 2 = 6 - 2 = 4 m

Length of Mary's rope =   x + 1 = 6 + 1 = 7 m

what's the equation of a line with slope 5 and y-intercept -2

Answers

Answer:

y = 5x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b where m = slope and b = y-intercept

Slope-Intercept Form: y = 5x - 2

Answer

Slope-intercept form: y=5x-2

Standard form: 5x-y=2

Explanation

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. You can just plug in the numbers to go y=5x-2.

Standard form is Ax+By=C. This form is usually used to find the x-intercept and y=intercept. You can rearrange the numbers to get standard form; 5x-y=2.

Two cars that are 600km apart are moving towards each other. Their speeds differ by 6km per hour and the cars are 123km apart after 4.5 hours. Find the speed of each car

Answers

Answer: [tex]56\ kmph,\quad 50\ kmph[/tex]

Step-by-step explanation:

Given

Two cars are 600 km apart moving towards each other

Difference in their speed is 6 kmph

After 4.5 hr, they are 123 km apart that is, they covered a distance of [tex]600-123=477\ km[/tex] in 4.5 hours

Suppose their speeds is [tex]v_1\ \text{and}\ v_2[/tex]

[tex]\therefore v_1-v_2=6\quad \ldots(i)[/tex]

Also, distance traveled is given by

[tex]\Rightarrow 477=[v_1+v_2]4.5\\\Rightarrow v_1+v_2=106\quad \ldots(ii)[/tex]

Solve, (i) and (ii) , we get [tex]v_1=56\ kmph\ \text{and}\ v_2=50\ kmph[/tex]

The second sail has one side of length 22 feet and another of length 2 feet. Determine the range of possible lengths of the third side of the sail.

Answers

Answer:

20 < L < 24

Step-by-step explanation:

We know that in any given triangle, the length of two sides is always greater than the length of the third side.

Since the sail is a triangle having length of one side as 22 feet and the length of another side as 2 feet, and let L be the length of the third side.

It follows from our triangle rule of sides above that

22 + 2 > L  (1)

22 + L > 2   (2)and

L + 2 > 22   (3)

It follows that from (1)

22 + 2 > L  

⇒  24 > L (4)

It follows that from (2)

22 + L > 2

⇒ L > 2 - 22

⇒ L > - 44  (5) and

It follows that from (3)

L + 2 > 22

⇒ L > 22 - 2

⇒ L > 20  (6)

Since from (5) and (6),

L > -44 and L > 20

and 20 > -44 ⇒ L > 20

⇒ 20 < L (7)

From (4) 24 > L ⇒ L < 24 (8)

Combining (7) and (8), we have

20 < L < 24

So, the possible range of values of the third side are 20 < L < 24

d²y/dx²=12x-12. express y in terms of x​

Answers

Answer:

y(x)=2x^3-6x^2+ax+b, a and b are constants

Step-by-step explanation:

d2y/dx2=12x-12, integrating both sides we get

dy/dx=6x^2-12x+a, where a is the integration constant.

Again integrating both sides, we get

y(x)=2x^3-6x^2+ax+b, where b is the integration constant

a) 2/3 x
b) 3/4 x
c) 4/3 x
d) 5/3 x

Answers

Answer:

d)

Step-by-step explanation:

3c/d = 5x

c/d = 5x/3 = 5/3 × x

f ( x ) = 1 x − 6 , g ( x ) = 6 x + 1 x Use composition to prove whether or not the functions are inverses of each other. Express the domain of the compositions using interval notation.

Answers

Answer:

Two functions f(x) and g(x) are inverses if and only if:

f( g(x) ) = x

and

g( f(x) ) = x

In this case, we have:

f(x) = 1*x - 6

g(x) = 6*x + 1

Let's check if the functions are inverses.

f( g(x) ) = 1*g(x) - 6 = 1*(6x + 1) - 6 = 6x + 1 - 6 = 6x - 5

and

g( f(x) ) = 6*f(x) + 1 = 6*(1x - 6) + 1 = 6x - 36 + 1 = 6x - 35

So we can see that:

f( g(x) ) ≠ x

g( f(x) ) ≠ x

Thus, f(x) and g(x) are not inverses.

Particularly, the two compositions are:

f( g(x) ) =  6x - 5

g( f(x) ) =  6x - 35

Both of these are linear functions, thus the domain in both cases is the set of all real numbers, that can be written as:

domain = (-∞, ∞)
