Answer:

.1273 mi = 627.2 feet

c = 2[tex]\pi[/tex]r

.4 = 2[tex]\pi[/tex]r

r = [tex]\frac{.4}{2\pi }[/tex]

r = [tex]\frac{.2}{\pi }[/tex]

d = [tex]\frac{.4}{\pi }[/tex]

d = .1273 mi = 627.2 feet

Step-by-step explanation:

Answer: I'll solve A) since there is a lot of work to be shown.

Step-by-step explanation:

A)

(x−1)³+3x(x−4)+2=x³

Use binomial theorem to expand  (x−1)³

x³- 3x² + 3x - 1 + 3x(x-4) + 2=x³

Use distributive property on 3x(x-4)

x³- 3x² + 3x - 1 + 3x²-12x + 2=x³

Add like terms

x³ −9x + 1 =x³

Subtract x³ from both sides.

x³ −9x +1 -x³ = 0

Add x³ and -x³

−9x+1=0

Subtract 1 from both sides. Anything subtracted from zero gives its negation.

−9x=−1

Divide both sides by -9.

x= 1/9

Answer:

1

Step-by-step explanation:

Let,

x1 = - 2

y1 = 5

x2 = 2

y2 = 9

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope

= ( 9 - 5 ) ) / ( 2 - ( - 2 )

= 4 / 4

= 1

Answer:

slope is 1

Step-by-step explanation:

from (-2, 5) to (2,9)

slope m= (y2-y1) / (x2-x1) = (9-5) / (2- -2) = 4 / 4 =1

*

you can think of how do you get from one point to the other

first point  (-2, 5) go to second point  (2,9)

-first on the  y-axis (vertical) you start at 5 and go four up to get to 9  

-second on the x-axis (horizontal) you start at -2 and go four right to get to 2

slope = change in y / change in x = four up /four right = 4/4 = 1

-moving down or to the left will make the numbers negative

Answer:

-3

Step-by-step explanation:

You have to bring -16 to the other side by adding.

It would make it: -7a=21

Then you hve to diving the -7.

-7a/-7=21/-7

That would equal -3

Answer:

A= -3

Step-by-step explanation:

-7a - 16 = 5

( -7a - 16) + 16 = 5 + 16

-7a - 16 + 16 = 21

-7a = 21

7a/7 = - 21/7

a = -3

Answer:

A, 3 root 3

Step-by-step explanation:

The triangle is a 30-60-90 Triangle meaning that the shortest side can be multiplied by 2 to get the hypotenuse or the slanted/longest side.

The second longest side of this triangle will always be the shortest side times root 3. Use the chart as a reference.

Answer:

3√3

Step-by-step explanation:

Angle ratio = 30 : 60 : 90

Side ratio = a : a√3 = 2a

Side opposite to 90° =  2a

2a = 6

 a = 6/2

a = 3

Side opposite to 60°  = a√3

x = a√3 =3√3

Answer:

(2, 3)

Step-by-step explanation:

Countless symmetry axis of a parabola is vertical line which divides the parabola into two congruent halves.

The axis of symmetry always passes through vertex of parabola. These will cause the plane to divide into two parts.

The geometric shape may have countless symmetry axis. This actually divides the shape into two halves and creates a mirror like effect.

The x-coordinate of vertex is equation of axis symmetry of parabola. Lets say if we take an example of quadratic equation which is ,

y = ax^2 + bx + c , here in this equation the axis of symmetry is vertical line which is x = - b^2 a

Answer:

$3.20 / kg

Step-by-step explanation:

$1.44 / pound

so, this is normed to 1 pound = 0.45 kg.

now we want to transform that to have 1 kg as the norming unit.

for this we need to multiply the top and the bottom of the ratio with the same number, so that the value of the ratio remains unchanged, but that the bottom turns into 1 kg.

so, what do we need to turn 0.45 into 1 ?

0.45 × x = 1

x = 1/0.45 = 1/1 / 45/100 = 100/45 = 20/9 = 2.22222...

since we need to multiply top and bottom with the same factor, we get

(1.44/0.45) × (2.222222/2.222222) =

(1.44 × 2.222222) / (0.45×2.222222) =

(1.44 × 2.222222) / 1kg = $3.20 / kg

the answer is number 4 or d

Answer:

∠ DCV = ∠ VBD = 50°

Step-by-step explanation:

The inscribed angles DCV and VBD are half the measure of their intercepted arcs, that is

∠ DCV = [tex]\frac{1}{2}[/tex] DV = [tex]\frac{1}{2}[/tex] × 100° = 50°

∠ VBD = [tex]\frac{1}{2}[/tex] DV = [tex]\frac{1}{2}[/tex] × 100° = 50°

Here we have a quadratic function and we want to find the value of a constant with a given restriction.

We will find that c = 8.

So we have the function:

[tex]f(x) = -2c + cx - x^2[/tex]

We know that:

[tex]f(5)^{-1} = -1 = \frac{1}{-2c + c\cdot 5 - (5)^2}[/tex]

Notice that the above equation means that:

[tex]-2c + c\cdot5 - (5)^2 = -1[/tex]

Then we just need to solve the above equation for c:

[tex]-2c + 5c - (5)^2 = -1\\\\(-2 + 5)\cdot c - 25 = -1\\\\3\cdot c = -1 + 25\\\\3\cdot c = 24\\\\c = 24/3 = 8[/tex]

So we found that the value of c is 8.

This means that the function is:

[tex]f(x) = -16 + 8\cdot x - x^2[/tex]

Answer:

y = -2/9x+2/3

Step-by-step explanation:

First find the slope

m= (y2-y1)/(x2-x1)

   = (0-2)/(-3-6)

   = -2 /-9

  2/9

The slope intercept form is

y= mx+b  where m is the slope and b is the y intercept

y = 2/9x+b

Using the point -3,0

0 = 2/9(-3) +b

0 = -2/3+b

b = 2/3

y = -2/9x+2/3
