What is the slope intercept form of the equation of the line passing through (1,2) and (3,10).

Answer:

12 m

Step-by-step explanation:

If 1 m = 3.3 feet, then,

1 feet = 1/3.3 m

So,

39.6 feet

= 39.6/3.3

Multiplying by 10....

= 396/33

= 12 m

Solution :-

From the given figure we can see that the prism is made up of

And the base and height of each triangle is ,

And the dimensions of each rectangle is ,

Therefore , the Total surface area is ,

→ TSA = 2( area of each ∆) +3(area of each rectangle)

→ TSA = 2 ( 1/2 * 7 * 5)in.² + 3(13*6.1) in.²

→ TSA = 2 * 35/2 in.² + 3* 79.3 in.²

→ TSA = 35 in.² + 237.9 in.²

→ TSA = 272.9 ≈ 273 in.²

Hence the TSA of prism is 273 in.² .

Answer:

[tex]x= 4[/tex]

Step-by-step explanation:

[tex]\frac{\sqrt{2x}}{\sqrt{x-2}\:}=2[/tex]                       [ bring √(x - 2) to the opposite side ]

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

[tex](\sqrt{2x} )^{2} = (2\sqrt{x-2})^2[/tex]      [ square both sides ]

[tex]2x = 4(x-2)[/tex]  

[tex]2x=4x-8[/tex]

[tex]2x - 4x = -8[/tex]

[tex]-2x = -8[/tex]

[tex]x= 4[/tex]

Answer:

x=4

Step-by-step explanation:

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

Multiply both sides by [tex]\sqrt{x-2}[/tex] :

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

Square both sides:

[tex]\implies 2x=4(x-2)\\\\\implies 2x=4x-8[/tex]

Add 8 to both sides:

[tex]\implies 2x+8=4x[/tex]

Subtract [tex]2x[/tex] from both sides:

[tex]\implies 8=2x[/tex]

Divide both sides by 4:

[tex]\implies x=4[/tex]

Answer:

y = 2x

the formula for linear equations are y = mx+c,

where m is the gradient,

and c is the y-intercept

to find m (the gradient):

1. pick to points on the graph (eg. -2,-4 and 2,4)

2 substitute the values into the formula for gradient y2-y1/x2-x1.

m = y2-y1/x1-x2

= -4 -4/-2-2

= -8/-4

= 2

to find c (y-intercept):

- the y-intercept is where the graph cuts the y axis

- in this graph, the y-intercept is 0

hence,

c = 0

substitute m = 2 and c = 0 to y = mx+c,

y = 2x + 0

y = 2x

hence, the equation that best represents the relationship shown in the graph is y = 2x.

Answer:

here's your answer hope it helps.

Step-by-step explanation:

1. decimal:

39/50=0.78

2. percentage:

39/50=78%

9/50 to a decimal is 0.78 and a percent is 78%.

To convert fraction into decimal, divide the top of the fraction by the bottom number (39/50) here 39 is the top of the fraction and 50 is bottom of the fraction.

39/50 = 0.78

To convert fraction into percent, divide the top of the fraction by the bottom number then multiple the result by 100 here 39 is the top of the fraction and 50 is bottom of the fraction then multiple the result(0.78) by 100.

39/50 = 0.78 * 100 = 78.

Therefore, 39/50 to a decimal is  0.78 and a percent is 78%.

Answer:

0.8x - y = -1.8, x-int = 2.25, y-int = -1.8

Step-by-step explanation:

(-4, -5) and (1, -1)

slope = [(-5) - (-1)] / [(-4) - 1] = -4 / -5 = 4/5 = 0.8

Let y = 0.8 x + b

Sub (-4, -5) into it

-5 = 0.8 * (-4) + b = -3.2 + b

b = -5 + 3.2 = -1.8

The equation is y = 0.8x - 1.8

standard form: 0.8x - y = -1.8

let y = 0, 0.8x - 1.8 = 0

x = 1.8/0.8 = 2.25   (x-intercept)

let x = 0, y = -1.8    (y-intercept)

Rearranging the question,

SOLVE FOR Y IN TERMS OF X:

Answer:

There are no solutions to the system because the equations represent parallel lines.

Step-by-step explanation:

Answer:

What does 0 = −12 mean regarding the solution to the system? There are no solutions to the system because the equations represent parallel lines.

I don't know what table you have as reference, but I suspect it includes the following transforms:

[tex]1 \leftrightarrow \dfrac1s[/tex]

[tex]e^{at} \leftrightarrow \dfrac{1}{s-a}[/tex]

[tex]\cos(at) \leftrightarrow \dfrac{s}{s^2+a^2}[/tex]

[tex]\sin(at) \leftrightarrow \dfrac{a}{s^2+a^2}[/tex]

[tex]\cosh(at) \leftrigharrow \dfrac{s}{s^2-a^2}[/tex]

[tex]\sinh(at) \leftrigharrow \dfrac{a}{s^2-a^2}[/tex]

It probably also includes some more general properties, like

[tex]t f(t) \leftrightarrow -F'(s)[/tex]

[tex]e^{at} f(t) \leftrightarrow F(s-a)[/tex]

where F(s) is the Laplace transform of f(t).

Beyond these, you should also know the following identities:

[tex]\cosh(t) = \dfrac{e^t + e^{-t}}2[/tex]

[tex]\cosh^2(t) = \dfrac{1 + \cosh(2t)}2[/tex]

[tex]\cos^2(t) = \dfrac{1 + \cos(2t)}2[/tex]

[tex]\sin^2(t) = \dfrac{1 - \cos(2t)}2[/tex]

[tex]\sin(2t) = 2 \sin(t) \cos(t)[/tex]

[tex]\sin(t \pm T) = \sin(t) \cos(T) \pm \cos(t) \sin(T)[/tex]

Putting everything together, we have

• (a)

[tex]\cosh(t) \sin(t) = \dfrac{e^t + e^{-t}}2 \times \sin(t) = \dfrac12 e^t \sin(t) + \dfrac12 e^{-t} \sin(t)[/tex]

and the Laplace transform is

[tex]\dfrac12 F(s - 1) + \dfrac12 F(s + 1)[/tex]

where F(s) is the transform of sin(t),

[tex]F(s) = \dfrac{1}{s^2 + 1}[/tex]

Then

[tex]\cosh(t) \sin(t) \leftrightarrow \dfrac{\frac1{(s-1)^2+1} + \frac1{(s+1)^2+1}}2 = \boxed{\dfrac{s^2+2}{s^4+4}}[/tex]

• (b)

[tex]\sin^2(t) = \dfrac12 \left(1 - \cos(2t)\right)[/tex]

and the transform is

[tex]F(s) = \dfrac12 \left(\dfrac1s - \dfrac{s}{s^2+4}\right) = \boxed{\dfrac{2}{s^3+4s}}[/tex]

• (c)

[tex]\cos^2(2t) = \dfrac12 \left(1 + \cos(4t)\right)[/tex]

with transform

[tex]F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2+16}\right) = \boxed{\dfrac{s^2+8}{s^3+16s}}[/tex]

• (d)

[tex]\cosh^2(t) = \dfrac12 \left(1 + \cosh(2t)\right)[/tex]

with transform

[tex]F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2-4}\right) = \boxed{-\dfrac2{s^3-4s}}[/tex]

• (e)

[tex]t\sinh(2t) \leftrightarrow -F'(s)[/tex]

where F(s) is the Laplace transform of sinh(2t),

[tex]F(s) = \dfrac{2}{s^2 - 4} \implies -F'(s) = \boxed{\dfrac{4s}{(s^2-4)^2}}[/tex]

• (f)

[tex]\sin(t) \cos(t) = \dfrac12 \left(2\sin(t) \cos(t)\right) = \dfrac12 \sin(2t)[/tex]

with transform

[tex]F(s) = \dfrac12 \times \dfrac{2}{s^2+4} = \boxed{\dfrac1{s^2+4}}[/tex]

• (g)

[tex]\sin\left(t+\dfrac\pi4\right) = \sin(t) \cos\left(\dfrac\pi4\right) + \cos(t) \sin\left(\dfrac\pi4\right) = \dfrac1{\sqrt2} \left(\sin(t) + \cos(t)\right)[/tex]

with transform

[tex]F(s) = \dfrac1{\sqrt2} \left(\dfrac1{s^2+1} + \dfrac{s}{s^2+1}\right) = \boxed{\dfrac{s+1}{\sqrt2 (s^2+1)}}[/tex]

The last two are trivial and follow directly from the properties listed above.

• (h)

[tex]\cos(2t) - \cos(3t) \leftrightarrow \dfrac{s}{s^2+4} - \dfrac{s}{s^2+9} = \boxed{\dfrac{5s}{s^4 + 13s^2 + 36}}[/tex]

• (i)

[tex]\sin(2t) + \cos(4t) \leftrightarrow \dfrac2{s^2+4} + \dfrac{s}{s^2+16} = \boxed{\dfrac{s^3+2s^2+4s+32}{s^4+20s^2+64}}[/tex]

Answer:

[tex]area = \frac{1}{2} (base)(height) \\ area = \frac{1}{2} (35cm)(12cm) \\ area = \frac{1}{2} (420 {cm}^{2} ) \\ area = 210 \: {cm}^{2} [/tex]

The area of the triangle with height 12 cm and base 35 cm is A = 210 cm²

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the base of the triangle is AB = 35 cm

The height of the triangle is BC = 12 cm

And , the area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

Area of the triangle A = ( 1/2 ) x 12 x 35

Area of the triangle A = ( 6 x 35 )

Area of the triangle A = 210 cm²

Hence , the area of the triangle is 210 cm²

That means Kali runs 4,000 meters each day.

Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.

The final step is to divide. 12/4 = 3

So, it would take 3 days for him to run a total of 12 kilometers.
