18

Answer:

(B)

Step-by-step explanation:

v^2 = v0^2 + 2ax

a = (v^2 - v0^2) / 2x

= (20^2 - 10^2) / 200

= 1.5 m/s

Answer:

1.false

2.false

3.false

Answer:

All three are false.

Step-by-step explanation:

Let's say a equaled 2 and b equaled 5.

For reference: |2| = 2 |5| = 5

2 > 5 - False

|2| > |5| - False

2 > |5| - False

Hope this helps!!

Answer: B  - 3 3/4 cubic inches

Step-by-step explanation:

A = BH; B = wl

2 * 1 1/4 = B

B = 2 1/2

H = 1 1/2

2 1/2 * 1 1/2 = 3 3/4

Answer:

∫ F dr= 1

c

Step-by-step explanation:

The correct question is -

Given - [tex]F = < \frac{sec^{2} x}{y} , - \frac{tan x}{y^{2} }>[/tex] and C : (0, 1) to [tex](\frac{\pi }{4} , 1)[/tex]

To find - Evaluate and input the result of the following integral.

Proof -

We know that,

dr = dx i + dy j

F = < F1, F2 >

Now, we know

[tex]d(\frac{tanx}{y }) = \frac{d}{dx}(\frac{tanx}{y}) + \frac{d}{dy}(\frac{tanx}{y})[/tex]

So,

[tex]\frac{d}{dx}(\frac{tanx}{y}) =\frac{1}{y} \frac{d}{dx}({tanx}) \\\\ = \frac{sec^{2} x}{y} \\\frac{d}{dy}(\frac{tanx}{y}) = tanx \frac{d}{dy}(y^{-1}) \\ = -\frac{tanx}{y^{2} }[/tex]

Now,

We can see that,

[tex]d(\frac{tanx}{y }) = \frac{sec^{2} x}{y} dx - (\frac{tanx}{y^{2} })dy[/tex]

So,

[tex]\int\limits^{}_C {F. dr} = \int\limits^{}_C d(\frac{tanx}{y} )\\= [\frac{tanx}{y} ]\limits^{(\frac{\pi }{4} ,1)}_{(0,1)}\\= [\frac{tanx}{y} ]\limits^{}_{(\frac{\pi }{4} ,1)} - [\frac{tanx}{y} ]\limits^{}_{(0,1)}\\= \frac{tan(\frac{\pi }{4} )}{1} - \frac{tan 0}{1}\\= 1 - 0\\= 1[/tex]

∴ we get

∫ F dr= 1

Answer:

1. 30 in

2. 273 mi

3. 248 m

Step-by-step explanation:

For the first circle, you are given the radius. Multiply that by 2 in order to get 30.

For the second circle, you are given the diameter. Divide that by 2 to get 273.

For the third circle, you are given the radius. Multiply that by 2 in order to get 248.

Answer:

Paul spent $12.65

Step-by-step explanation:

Create a system of equations where p is how much Paul spent and t is how much Tammy spent.

p + t = 37.85

p = t - 12.55

Solve by substitution:

p + t = 37.85

(t - 12.55) + t = 37.85

2t - 12.55 = 37.85

2t = 50.4

t = 25.2

Find how much Paul spent by plugging in 25.5 as t into p = t - 12.55

p = t - 12.55

p = 25.2 - 12.55

p = 12.65

So, Paul spent $12.65

Answer:

13.70

Step-by-step explanation:

a^2+b^2=c^2

a = side 1

b = side 2

c = hypotenuse

9.2^2 + b^2 = 16.5^2

272.25 - 84.64 = 187.61 =b^2

√187.61 = b = 13.697 = 13.70

Answer:

see I hope u understand

Answer:

SEE BELOW

Step-by-step explanation:

Since,  △ABC  is a right angled triangle. We can apply Pythagoras' Theorem to find the length of AB.

According to Pythagoras’ theorem, “In a right angled triangle: The square of the hypotenuse is equal to the sum of the squares of the other two sides.”

Applying Pythagoras’ theorem in  △ABC,  we get

AB2=AC2+BC2  

⇒AB2=52+122  

⇒AB2=25+144  

⇒AB2=169  

⇒AB=169−−−√  

⇒AB=13  cm

Step-by-step explanation:

AB = 12 cm

BC = 5 cm

AC = .......?

Use pythagoras theorem

[tex] {ac}^{2} = {ab}^{2} + {bc}^{2} \\ {ac}^{2} = {12}^{2} + {5}^{2} \\ ac = \sqrt{144 + 25} \\ ac = \sqrt{169} \\ ac = 13 \: cm[/tex]

Answer:

[tex](a)\ y = 26 + 0.44x[/tex]

[tex](b)\ 114\ copies[/tex]

Step-by-step explanation:

Given

[tex]Base\ Charge = \$26[/tex]

[tex]Rate = 44c[/tex] per copy

Solving (a): Linear Equation

The total charges (y) is: the base charge + the rate * number of copies (x).

So, we have:

[tex]y = 26 + 0.44 * x[/tex]

The 0.44 is 44 cents converted to dollars

[tex]y = 26 + 0.44x[/tex]

Solving (b): Purchase if he budgets $76.16

This implies that y = 76.16

So, we have:

[tex]y = 26 + 0.44x[/tex]

[tex]76.16 = 26 + 0.44x[/tex]

Collect like terms

[tex]0.44x = 76.16 - 26[/tex]

[tex]0.44x = 50.16[/tex]

Solve for x

[tex]x = \frac{50.16}{0.44}[/tex]

[tex]x = 114[/tex]

Answer:

  one solution

Step-by-step explanation:

There will be one solution if the left-side x-coefficient is different from the right-side x-coefficient.

Simplifying, we get ...

x + 1/2x -2 = 1/2x +6x -12

3/2x -2 = 13/2x -12

The left-side coefficient is 3/2, which is different from the right-side coefficient of 13/2. The equation will have one solution.

__

Add 12-3/2x to both sides to get ...

  10 = 5x

  2 = x . . . . . divide both sides by 5. This is the solution.

Answer:

x<4

Answer:x<4

Step-by-step explanation:

3x/3 < 12/3

Answer:

80

Step-by-step explanation:

x + (2x-60) = 180

combine like terms

3x - 60 =180

add 60 to both sides

3x = 240

divide both sides by 3

x = 80

plug it back in to check

80 + (2(80) - 60 = 180

80 + (160 -60) = 180

80 + (100) = 180

180 = 180
