Step-by-step explanation:

Given equation is

[tex]\sqrt{2}\cos x-1=0[/tex]

solving this

[tex]\sqrt{2}\cos x=1\\\cos x=\frac{1}{\sqrt{2}}[/tex]

There can be two solution because [tex]0<x<2\pi[/tex]

[tex]\cos x=\cos \frac{\pi }{4}\ or\ \cos (2\pi -\frac{\pi}{4})\\[/tex]

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

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.

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

Answer:

67[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Assuming you require to simplify the expression.

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying the radicals

[tex]\sqrt{72}[/tex] = [tex]\sqrt{36(2)}[/tex] = [tex]\sqrt{36}[/tex] × [tex]\sqrt{2}[/tex] = 6[tex]\sqrt{2}[/tex]

[tex]\sqrt{242}[/tex] = [tex]\sqrt{121(2)}[/tex] = [tex]\sqrt{121}[/tex] × [tex]\sqrt{2}[/tex] = 11[tex]\sqrt{2}[/tex]

Then

2[tex]\sqrt{72}[/tex] + 5[tex]\sqrt{242}[/tex]

= 2(6[tex]\sqrt{2}[/tex] ) + 5(11[tex]\sqrt{2}[/tex] )

Answer:

16/35

Step-by-step explanation:

From the question we are given:

total number of cupcakes needed for the school dance = 140 cupcakes

Lucy made 35cupckes

JoJo made 42 cupcakes

Total cupcakes made by JoJo and Lucy = 35+42 = 76cupcakes

Remaining cupcakes still needed to be made = 140 - 76 = 64cupckes

Fraction of the cupcakes that Lucy and JoJo still need to make = 64/140

Fraction of the cupcakes that Lucy and JoJo still need to make = 16/35

Hence the fraction of the cupcakes that Lucy and JoJo still need to make is 16/35

Answer and explanation:

The signs -1 and -4 lie on the negative side of the number line, left of zero(positive right of zero).

The opposites for each number would be +1 and +4 which would all be on the right side of zero on the number line

Inequality signs or statements to represent greater and lesser number on the number line using the numbers above as examples would be:

-1<+1

-4<-1

+1>-1

+1<4

-1-4<1+4

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

Answer:

Steps below

Step-by-step explanation:

(3/x²)+ 2/x =1   (x ≠ 0)

(3/x²) + 2x/x² = 1

(3 + 2x) / x² = 1

3 + 2x = x²

x² - 2x - 3 = 0

(x + 1) (x - 3) =0

x = -1 or x = 3

When a hexagon is rotated 60° counterclockwise, it is carried onto itself.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rotation is the rotation of a figure about a given point.

The exterior angles of a regular hexagon measures 60 degrees each, hence:

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

Answer:

f(X)= 3x^2- 30x+5

Step-by-step explanation:

f(X)= 3(x-5)^2-70

= 3(x^2-2.x.5+ 5^2) -70

= 3(x^2-10x+25)-70

= 3x^2-30x+75-70

= 3x^2-30x+5

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.

Step-by-step explanation: Given that: There are 5 butterflies onscreen

The number of butterflies doubles every minute.

That is every increase in minute = double in the numbers of butterflies

Expressing in the power of 2

= 5×2^n. .......... 1

Where n is 4 which can as well range from ( 1,2,3,4 )

Hence, using the expression in equation 1

Ist minute where n = 1

5(2^1) = 10 butterflies

2nd minutes: where n = 2

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

After 3rd minutes :

5(2^3) butterflies where n = 3

After 4th minutes : where n = 4

5(2^4) butterflies

But at that point she was able to capture 4.

After 4 min, number on screen = 5(2^4) - 4

= 5(16) - 4

= 80-4

= 76

[tex]\frac{2}{k+2}[/tex]

Step-by-step explanation:

Given the expression:

[tex]\frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}[/tex]

We are to find the product as shown:

[tex]= \frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{k^2-2^2} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{(k-2)(k+2)} * \frac{k-2}{2k+1}\\\\= \frac{2}{k+2} * 1\\\\= \frac{2}{k+2}[/tex]

Hence the required function is [tex]\frac{2}{k+2}[/tex]

4.7n=-4.4n+2.94-1.83

4.7n=-4.4n+1.11

4.7n+4.4n=1.11

n=1.11/9.1

n=0.121978

Answer:

n=-3.7

Step-by-step explanation:

1.6-4.7n+0.23=-4.4n+2.94

-4.7n+1.83=-4.4n+2.94

+4.4n both sides

-0.3n+1.83=2.94

-1.83 both sides

-0.3n=1.11

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.
