3. While playing a game Sarah defeated 5 enemies with each enemy defeated
earning her 9,702 points. If she traded in all her points for 7 extra lives, how
many points is it per life?

Answer:

[tex]a=\frac{1}{2}\times \: h(a+b)[/tex]

[tex] \frac{1}{2 } \times 9(18 + 24) [/tex]

24 + 18=42

[tex] = \frac{1}{2} \times 9(42)[/tex]

[tex] \frac{1}{2} \times 378[/tex]

=189cm²

Answer:

[tex]Solid\ A= 180km^3[/tex]

[tex]Solid\ C = 28.8km^3[/tex]

Step-by-step explanation:

Given

[tex]k_1 = \frac{2}{5}[/tex] from A to B

[tex]k_2 = \frac{2}{5}[/tex] from B to C

[tex]Solid\ B = 72km^3[/tex]

Required

Find the volumes of solids A and C

The expression that gives solid B from A is:

[tex]Solid\ A * k_1 = Solid\ B[/tex]

This gives:

[tex]Solid\ A * \frac{2}{5}= 72km^3[/tex]

Make A the subject

[tex]Solid\ A= 72km^3 * \frac{5}{2}[/tex]

[tex]Solid\ A= 36km^3 * 5[/tex]

[tex]Solid\ A= 180km^3[/tex]

Similarly:

The expression that gives solid C from B is:

[tex]Solid\ B * k_2 = Solid\ C[/tex]

This gives:

[tex]72km^3 * \frac{2}{5} = Solid\ C[/tex]

[tex]\frac{144km^3 }{5} = Solid\ C[/tex]

[tex]28.8km^3 = Solid\ C[/tex]

[tex]Solid\ C = 28.8km^3[/tex]

Answer: Wall 1 & 2 : 26 ft by 9 ft

Wall 3 : 18 ft by 9 ft

Area 1 : 26 ft x 9 ft = 234 ft²

Area 2 : 26 ft x 9 ft = 234 ft²

Area 3 : 18 ft x 9 ft = 162 ft²

Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²

1 Gallon = 250 ft²

630 ft² ÷ 250 ft² per gallon = 2.52 gallons

The final statement is The linear equation is xx₁+xy₁=6532

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here: Total trackers sold =42 and total sales=$6574

let x models of 1st model and 42-x models of 2nd model be sold and their respective selling price be x₁ and y₁, then we have

xx₁+42+xy₁=6574

xx₁+xy₁=6532

Hence, The linear equation is xx₁+xy₁=6532

Answer:

The result of the integral is:

[tex]\arcsin{(\frac{x}{3})} + C[/tex]

Step-by-step explanation:

We are given the following integral:

[tex]\int \frac{dx}{\sqrt{9-x^2}}[/tex]

Trigonometric substitution:

We have the term in the following format: [tex]a^2 - x^2[/tex], in which a = 3.

In this case, the substitution is given by:

[tex]x = a\sin{\theta}[/tex]

So

[tex]dx = a\cos{\theta}d\theta[/tex]

In this question:

[tex]a = 3[/tex]

[tex]x = 3\sin{\theta}[/tex]

[tex]dx = 3\cos{\theta}d\theta[/tex]

So

[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9-(3\sin{\theta})^2}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9 - 9\sin^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{\theta})}}[/tex]

We have the following trigonometric identity:

[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]

So

[tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex]

Replacing into the integral:

[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{2}{\theta})}} = \int{\frac{3\cos{\theta}d\theta}{\sqrt{9\cos^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{3\cos{\theta}} = \int d\theta = \theta + C[/tex]

Coming back to x:

We have that:

[tex]x = 3\sin{\theta}[/tex]

So

[tex]\sin{\theta} = \frac{x}{3}[/tex]

Applying the arcsine(inverse sine) function to both sides, we get that:

[tex]\theta = \arcsin{(\frac{x}{3})}[/tex]

The result of the integral is:

[tex]\arcsin{(\frac{x}{3})} + C[/tex]

Answer:

Step-by-step explanation:

one-half(x + 1) = (y – 5)^2, written symbolically, is (1/2)(x - [-1]) = (y - 5)^2

or x + 1 = 2(y - 5)^2 (after multiplying all terms by 2).   Because the y term is squared, we know immediately that the graph is a horizontal (not vertical) parabola.  

This equation (immediately above) can be written as

x = 2(y - 5)^2 - 1

The standard equation of a horizontal parabola with vertex (h, k) is x = c(y - k)^2 + h.  Comparing this to the given quadratic:  

we see that k = 5 and h = -1.  This tells us that the vertex of this graph is (-1, 5), and that the graph is stretched horizontally because c = 2 is greater than 1.

To graph this, it's best to make a short table of points, as follows, remembering that y is the independent value and x depends on y through the equation given above.

 y    x = 2(y - 5)^2 - 1    (x, y)

 0    x = 49                    (49, 0)

 2    x = 2(-3)^2 - 1         (17, 2)

  1   x = 2(-4)^2 - 1          (31,  1)

  vertex (already found) (-1, 5)

The graph of equation 1/2(x+1)=[tex](y-5)^{2}[/tex] looks like graph of a horizontal parabola.

Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.

one-half(x + 1) = (y – 5)^2, written symbolically, is (1/2)(x - [-1]) = [tex](y-5)^{2}[/tex]

or x + 1 = 2[tex](y-5)^{2}[/tex]. Because the y term is squared, we know immediately that the graph is a horizontal (not vertical) parabola.  

This equation can be written as

x = 2[tex](y-5)^{2}[/tex] - 1

The standard equation of a horizontal parabola with vertex (h, k) is

x = c[tex](c-k)^{2}[/tex] + h.  Comparing this to the given quadratic:  

we see that k = 5 and h = -1.  This tells us that the vertex of this graph is (-1, 5), and that the graph is stretched horizontally because c = 2 is greater than 1.

To graph this, it's best to make a short table of points, as follows, remembering that y is the independent value and x depends on y through the equation given above.

y    x = 2[tex](y-5)^{2}[/tex] - 1    (x, y)

0    x = 49                    (49, 0)

2    x = 2(-3)^2 - 1         (17, 2)

 1   x = 2(-4)^2 - 1          (31,  1)

Answer

Roundworm is 9ft long and the tapeworm is 60 feet long

Step-by-step explanation:

If we turn this into an algebraic equation we get 8x-3=69 with 8x being x + 7x because we know that the tape worm is about 7 times longer than the round worm and the roundworms length would be x here. We have the -3 because it is 3 minus 7 times the total length. We do this and eventually end up with x = 9 which is the length of the roundworm. We multiply that by 7 to get 63 and subtract 3 to get 60. If you want to check if this is right do 60+9 and you'll get 69 which is the total of them end to end. (also 69 funny haha)
