Answer:

[tex]k = \frac{2P}{x^2}[/tex]

Step-by-step explanation:

[tex]P= \frac{1}{2} kx^2\\\\P=\frac{kx^2}{2}\\\\ 2P =kx^2\\\\\frac{2P}{x^2}= \frac{kx^2}{x^2} \\\\k= \frac{2P}{x^2}[/tex]

Answer:

option (c) 2

Step-by-step explanation:

We have the linear equation :-

→ 3x - 8 = -2

add 8 both sides

→ 3x - 8 + 8 = -2 + 8

→ 3x = 6

→ x = 6 ÷ 3

→ x = 2

Answer:

Yes

Step-by-step explanation:

Answer: y=4x-2

Step-by-step explanation:

Slope-intercept form: y=ax+b, where a is the slope and b is the y-intercept.

Given: slope is 4, and y-intercept is -3

y=ax+b

y=4x+(-3)

y=4x-3

Answer:

the answer is 8.167

Step-by-step explanation:

Answer:

0.29 rounded to the nearest ones is 0.

0.29 rounded to the nearest tenths is 0.3

0.29 rounded to the nearest hundredths is 0.29

Step-by-step explanation:

Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.

Round to the nearest ones:

Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:

0.29 rounded to the nearest ones is 0.

Round to the nearest tenths:

Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:

0.29 rounded to the nearest tenths is 0.3

Round to the nearest hundredths:

Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).

0.29 rounded to the nearest hundredths is 0.29

Answer:

x = 0.8    y = 0.6

Step-by-step explanation:

Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.

Next plug in the value for y into the 1st equation, I got :

2x + 4 ( 2x - 1) = 4

Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.

Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1

Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.

Answer:

Gravitational potential energy = 320,460 joules

Step-by-step explanation:

Given:

Mass of tourist = 75 kg

Height = 436 m

Gravitational accelration = 9.8 N/kg

Find:

Gravitational potential energy

Computation:

Gravitational potential energy = mgh

Gravitational potential energy = (75)(9.8)(436)

Gravitational potential energy = 320,460 joules

Answer:

Step-by-step explanation:

ans=26.92

use trigonometric ratios

a²= b²+c²

a²=25²+10²

a²=625+100

now take square root on both sides

a

[tex] \sqrt{a { }^{2} } = \sqrt{725} [/tex]

a=26.92

a=27 (2decimal place)

Answer:

y = 2x

Step-by-step explanation:

The equation of a line is y = mx + b

We can plug in values for x and y,:

x = 1, y = 2

2 = m + b  <- equation 1

x = 4 y = 8

8 = 4m + b <- equation 2

We can multiply equation 1 by 4, getting 8 = 4m + 4b.

We can them subtract equation 1 by equation 2, getting 3b = 0.

Therefore, b = 0.

We can use the equation 2 = m + b and find m:

Since b = 0, m = 2.

The equation is then y = 2x.

Answer:

Step-by-step explanation:

So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.

Answer:

12

Step-by-step explanation:

max cap 670lb- delivery person 160lb  weight left 510lb

weight 510lb/each box 40lb number of boxes 12.75lb

each box 40lb times number of boxes 12lb  480lb+160lb 640lb

so your still have 30 lb before max weight of elevator

Answer: x=16

Step-by-step explanation:

For this problem, we can set a proportion to find the side length of the smaller rectangle.

[tex]\frac{15}{24}=\frac{10}{x}[/tex]                                     [cross multiply]

[tex]15x=240[/tex]                                 [divide both sides by 15]

x=16

Answer:

40

Step-by-step explanation:

Given:

Number of pieces:

w = 0.5 m

A = l × w

50m² = 100m × w

w = 50m²/100m

w = 0.5 m

Answer:

The answer is 0.5 m i.e Width = 0.5 m

Step-by-step explanation:

Given,

Area (A) = [tex]50m^{2}[/tex]

length (l) =100 m

width ( b ) = ?

Now,

 A = l * b

or, 50 = 100 * b

or, [tex]\frac{50}{100}[/tex]= b

or, b = 0.5 m

Answer:

[tex] \boxed{ \bold{ \huge {\boxed{ \sf{ \frac{25}{2} }}}}}[/tex]

Step-by-step explanation:

[tex] \sf{5 \div \frac{2}{5} }[/tex]

When any number of fraction is divided by a fraction , we multiply the dividend by reciprocal of the divisor.

We can obtain the reciprocal of any fraction by interchanging the position of numerator and denominator.

⇒[tex] \sf{5 \times \frac{5}{2} }[/tex]

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator.

⇒[tex] \sf{ \frac{5 \times 5}{2} }[/tex]

Multiply the numbers : 5 and 5

⇒[tex] \sf{ \frac{25}{2} }[/tex]

Hope I helped!

Answer:

6 possible outcomes

Step-by-step explanation:

To solve this problem, we have to make use of the Fundamental Counting Principle formula.

The formula counting principle states that when we are given two or more distinct events, in order to get the total number of possible outcomes, we multiply such events together.

In the above question, we are given two events.

Event 1

3 varieties of cheese: Cheddar, Gouda, and Swiss.

Event 2

2 styles of cheese: Shredded and Sliced

The possible outcomes for the variety and style of cheese = Event 1 × Event 2

= 3 × 2

6 possible outcomes.

These 6 Possible outcomes are listed below:

1) Cheddar cheese , Shredded

2) Cheddar cheese , Sliced

3) Gouda cheese , Shredded

4) Gouda cheese , Sliced

5) Swiss cheese , Shredded

6) Swiss cheese , Sliced
