Find The Value Of C. Give The Answer In Simplest Radical Form.

Answers

Answer 1

Answer:

x = 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + (2[tex]\sqrt{2}[/tex] )² = 4²

x² + 8 = 16 ( subtract 8 from both sides )

x² = 8 ( take the square root of both sides )

x = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

Explain how the net of rectangular prism can help you find the surface area or the prism?

Answers

A 3d cardboard box has 6 sides, each of which are rectangles. If you unfold the 3D box, and flatten it out, then you'll be left with 6 rectangles such as what you see in the attachment below. This is one way to unfold the box. This flattened drawing is the net of the 3D rectangular prism. You can think of it as wrapping paper that covers the exterior of the box. There are no gaps or overlapping portions. If you can find the area of each piece of the net, and add up those pieces, that gets you the total area of the net. This is the exactly the surface area of the box.

In the drawing below, I've marked the sides as: top, bottom, left, right, front, back. This way you can see how the 3D box unfolds and how the sides correspond to one another. Other net configurations are possible.

Explain why it makes sense that a system of two lines with equal slopes but different y-intercepts has no solutions.

Answers

Answer:

Please check explanations

Step-by-step explanation:

Here, we want to seek why the system has no solutions

An example is necessary

Let us have two lines with equal slopes and different y-intercepts

y = 2x + 5

y = 2x - 3

To solve this system, we equate the y-values

2x + 5 = 2x - 3

The reason why this has no solution is that there is no x value that would validate the equality

It is impossible to find an x value which when inserted would make both equations equal

In the absence of this, we can make that conclusion that the system of equations has no solution

Step-by-step explanation:

[tex] \frac{2}{3} x + 1 = \frac{1}{6}x - 7 \\ \frac{4}{6} x - \frac{1}{6} x = - 7 - 1 \\ \frac{3}{6} x = - 8 \\ \frac{1}{2} x = - 8 \\ \boxed{ x = - 16}[/tex]

The energy that generates wind comes from what source A. Soar radiation B. Magnetic attraction C. Moon's gravity D. Coriolis effect

Answers

Answer:

A. Soar radiation

Step-by-step explanation:

Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.

That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.

The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.

Therefore, the energy that generates wind comes from what source soar radiation.

Hence, option (A) is correct.

d is proportional to S^2
d=900 when s=20

calculate the value of D when S=25

Answers

Answer:

d = 1406.25

Step-by-step explanation:

Given d is proportional to s² then the equation relating them is

d = ks² ← k is the constant of proportion

To find k use the condition d = 900 when s = 20

900 = k × 20² = 400k ( divide both sides by 400 )

2.25 = k

d = 2.25s² ← equation of proportion

When s = 25, then

d = 2.25 × 25² = 2.25 × 625 = 1406.25

Answers

Answer:

6.4 feet

12.8 feet

14.8 feet

Step-by-step explanation:

let x = length of 1st side

let 2x = length of 2nd side

let 2x + 2 = length of 3rd side

add them all together and set sum equal to 34

x + 2x + 2x + 2 = 34

5x + 2 = 34

5x = 32

x = 6.4, which is 1st side

2x = 12.8, which is 2nd side

2x + 2 = 14.8, which is 3rd side

The Lopez family is traveling from the beach to their house at a average speed of 65 miles per hour. At noon, they have driven 50 miles. Which equation represents the total distance they have driven, d, in terms of the number of hours since noon, h?

Answers

The equation that represents the total distance they have driven, d, in terms of the number of hours since noon, h is:

d = 65h + 50

Which equation represents the total distance that the family has traveled?

The equation that represents the total distance that the family traveled must show the initial distance they started with, the velocity at which they are traveling and the time they have covered.

The initial distance that they started with is = 50 miles

The velocity at which they are traveling is 65miles/hr

Therefore the total distance they have driven, d, in terms of the number of hours since noon, h

= 65h + 50

Therefore, the third option is correct.

2nd minutes: where n = 2

5(2)(2) = 5(2^2) butterflies

After 3rd minutes :
