The distance of Mercury from sun will be 585,000,000 km.

It is given that it takes 3.25 minutes to light to reach from sun to mercury.

If speed of light is 3 ×  [tex]10^{5}[/tex] km/sec , then calculate the distance from sun to mercury.

What will be the value of (2 × [tex]x^{2}[/tex] ) ÷ 2 ?

The value will be  [tex]x^{2}[/tex] .

Distance travelled by light in 1 seconds = 3 ×  [tex]10^{5}[/tex] km

∵ 1 minute = 60 seconds

⇒  Distance travelled by light in 1 minute will be ;

   = 60 × 3 ×  [tex]10^{5}[/tex] km

⇒ Distance travelled by light in 3.25 minutes will be ;

   = 3.25 × 60 × 3 ×  [tex]10^{5}[/tex] km

   = 585,000,000 km

Thus , distance of Mercury from sun will be 585,000,000 km.

Answer:

20

Step-by-step explanation:

Let x be the number of cables.

Let y be the total cost.

Therefore,

West coast:  y = 4.39x + 38

East coast:   y = 3.14x + 63

if the total cost is the same, equate the equations and solve for x:

                  y = y

  4.39x + 38 = 3.14x + 63

4.39x - 3.14x = 63 - 38

            1.25x = 25

                   x = 25 ÷ 1.25 = 20

Therefore, the repair shop should purchase 20 cables for the total cost from each supplier to be the same.

Step-by-step explanation:

first we have to identify 72% as a decimal

72/100=0.72

then we have to multiply 0.72 by  $54.18.

0.72 x $54.18 = $39.01

Your dad paid $39.01, but now we have to identify how much is the total.

$54.18 + $39.01 = $93.19

  D.  right 4, down 8

Step-by-step explanation:

The usual transformations applied to functions are ...

  f(x) ⇒ f(x -h) . . . . translation right h units

  f(x) ⇒ f(x) +k . . . . translation up k units

  f(x) ⇒ k·f(x) . . . . . vertical scaling by a factor of k; reflection over x-axis when k < 0

  f(x) ⇒ f(x/k) . . . . . horizontal scaling by a factor of k; reflection over y-axis when k < 0

In the above, "scaling" will be expansion when |k| > 1, compression when |k| < 1.

__

Your transformation is ...

  x^2 ⇒ (x -4)^2 -8

  f(x) ⇒ f(x -4) -8

This is translation with h=4 and k=-8. That is, it is translation right 4 units and down 8 units.

Answer:

2.29 ft of side length and 1.14 height

Step-by-step explanation:

a) Volume V = x2h, where x is side of square base and h is hite.

Then surface area S = x2 + 4xh because box is open.

b) From V = x2h = 6 we have h = 6/x2.

Substitude in formula for surface area: S = x2 + 4x·6/x2, S = x2 + 24/x.

We get S as function of one variable x. To get minimum we have to find derivative S' = 2x - 24/x2 = 0, from here 2x3 - 24 = 0, x3 = 12, x = (12)1/3 ≅ 2.29 ft.

Then h = 6/(12)2/3 = (12)1/3/2 ≅ 1.14 ft.

To prove that we have minimum let get second derivative: S'' = 2 + 48/x3, S''(121/3) = 2 + 48/12 = 6 > 0.

And because by second derivative test we have minimum: Smin = (12)2/3 + 4(12)1/3(12)1/3/2 = 3(12)2/3 ≅ 15.72 ft2

The box dimensions that minimize the amount of material used are; side length of base = 3.30 ft and height = 1.65 ft

a) We know that a box has length, width and height and so volume of a box is;

V = L × W × H

Now, we are told the base of the box is square and if we label it x, then we have to function that models the volume as;

V = x²h

where x is side of square base and h is height.

Thus surface area function is;

S = x² + 4xh

b) We are told that the volume is 18 ft³ and so;

x²h = 18

Thus;

h = 18/x².

Put 18/x² for h in the surface area function to get: S = x² + 4x(18/x²)

S = x² + 72/x.

To get minimum, we have to find derivative of S. Thus;

S' = 2x - 72/x² = 0,

Thus;

2x³ = 72

x³ = 72/2

x³ = 36

x = 3.3 ft

Thus;

h = 18/3.3²

h = 1.65 ft

70 / 2 = 35 (UWT)

Since the other part is congruent, we can assume it is also 35.

Answer:

m∠UWV = 35°

Angle V is similar to Angle T

so angle V is 110°

m∠UWV = ( 180° - 110° ) ÷ 2
