Homework Jim Thompson! Part 1

Answer:

4x - 9x + 11 = -24

-5x + 11 = - 24

-5x = -24 - 11

-5x = -35

-5x/-5 = -35/-5

x = 7

Answer:

The answer is 7

Step-by-step explanation:

Firstly, you have to subtract 11 from -24, which is -35. Then, add the values with x. Which is -5. -35 divided by -5 equals 7. You can check the answer by doing (4*7)-(9*7)+11=-24

Answer:

bearing of Y from X is 074°

Step-by-step explanation:

the bearing of Y from X is the clockwise measure of the angle from the northline N to Y , that is

180° - 106° = 74°

the 3- figure bearing of Y from X is 074°

The value of the bearing of Y from X will be 74°.

What is Supplementary angle?

The sum of two or more angle is 180 degree then the angle is called the  Supplementary angle.

Given that;

The value of measure of ∠X = 106°

Now,

Since, The value of the bearing of Y from X will be calculated as;

∠X + ∠Y = 180°

106° + ∠Y = 180°

∠Y = 180° - 106°

∠Y = 74°

Thus, The value of the bearing of Y from X will be 74°.

Answer: C) [tex]B= 500(1.101)^{12t}[/tex]

Step-by-step explanation:

Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.

For monthly interest , Rate = [tex]\dfrac{r}{12}[/tex]

Time = 12 t  [ 1 year = 12 months ]

As r = 0.13 , so rate = [tex]\dfrac{0.13}{12}\approx0.010[/tex]

Now, the equation will be :

[tex]B=500 (1+0.101)^{12t}[/tex]

[tex]\Rightarrow\ B= 500(1.101)^{12t}[/tex]

Correct option : C) [tex]B= 500(1.101)^{12t}[/tex]

Answer:

The volume is [tex]275\pi\text{ yd}^3[/tex] or [tex]863.5\text{ yd}^3[/tex]

Step-by-step explanation:

The formula for the volume of a cylinder is [tex]V=\pi r^2 h[/tex], where r is the radius and h is the height. From the information provided, we have:

[tex]r=5 \text{ yd}\\h=11\text{ yrd}[/tex]

Using our equation, we get:

[tex]V=\pi (5)^2(11)\text{ yd}^3\\V=275\pi\text{ yd}^3\\V\approx 863.5\text{ yd}^3[/tex]

Answer:

B. [tex]4\sqrt{2}[/tex]

Step-by-step explanation:

EG is equal to 4

ED and DG, however, are equal to [tex]x\sqrt{2}[/tex]

So, we can do [tex]x\sqrt{2} = 4[/tex]

This comes out to [tex]x=2\sqrt{2}[/tex]

So, [tex]x^{2}[/tex] is the area of the square.

[tex]2\sqrt{2} ^{2}[/tex] is equal to [tex]4\sqrt{2}[/tex]

Answer:

666.66 years

Step-by-step explanation:

In this scenario, we need to find at what year both of the stalagmite crystals are at the exact elevation in the cave. So we need an algebraic formula to calculate this. Since the crystal in the ceiling is at a height of 10 feet (height of the cave) and is growing down we need to subtract its growth from its starting position of 10ft. The second crystal is starting at an elevation of 0 and growing upward so we simply need to chart its growth and equal both equations together to find its meet-up point. In this algebraic equation, x will equal the number of years that we need to find.

[tex]10 - 0.01x = 0.005x[/tex] ... add 0.01x to both sides.

[tex]10 = 0.015x[/tex]  ... divide both sides by 0.015

[tex]666.66 = x[/tex]

Finally, we can see that both crystals will meet-up after 666.66 years. If we plug this value into the equation we see that the crystals will meet-up at a point 3.33 ft above the cave floor.

Step-by-step explanation:

The family pack would be  £15 cheaper from the normal package.

In algebra, two or more equations to be solved together (i.e., the solution must satisfy all the equations in the system). For a system to have a unique solution, the number of equations must equal the number of unknowns.

Given that, A theme park sells entrance tickets. 2 adult tickets and 3 child tickets would cost a total of £72. 3 adult tickets and 1 child ticket would cost a total of £66. A family ticket costs £45 and allows entry for 2 adults and 2 children.

Let A represents adults and C represents children,

Establishing system of equation,

2A+3C = 72

3A+C = 66

On solving the equation, we get,

A = 18 and C = 12

For 2 adults, cost = 18x2 =  £36

For 2 children, cost = 12x2 =  £24

Total cost = 36+24 =  £60

In family pack, £45 allows entry for 2 adults and 2 children.

45 is 15 less 60

Hence, The family pack would be  £15 cheaper from the normal package.

Proof using Discrimant:

[tex]3 { x}^{2} - 2x + \frac{1}{3} = 0[/tex]

The discrimant is

[tex] \sqrt{ {b}^{2} - 4ac} [/tex]

B is -2, A is 3 and C is 1/3 so we get

[tex] \sqrt{ {2}^{2} - 4( 3)( \frac{1}{3}) } [/tex]

[tex] \sqrt{4 - 4} [/tex]

[tex] \sqrt{0 } = 0[/tex]

Since the discrimant equal zero, there is one real distinct zero.

This zero will also have a multiplicity of 2, so the zero is technically equal to each other.

To get better at solving, let solve for zero.

[tex]3 {x}^{2} - 2x + \frac{1}{3} = 0[/tex]

[tex]3( {x}^{2} - \frac{2}{3} x + \frac{1}{9} )[/tex]

Answer:

  follow directions. h represents a horizontal shift, + shifts to the right. k represents a vertical shift, + shifts up.

Step-by-step explanation:

Modern math instruction often tends toward giving you a task that is intended to help you discover for yourself particular mathematical relationships. This is one such task.

Here, you're intended to follow the instructions: using the technology provided (a graphing tool at the link) to discover the effect of changing the values of h and k in the function.

__

The first attachment shows plots from my graphing tool for different values of h. The red curve shows h=-2, the blue curve shows h=0, and the green curve shows h=1. If you look for the marked upward zero crossing, you see that it is unshifted for h=0, shifted left 2 units for h=-2, and shifted right 1 unit for h=1.

You are intended to conclude that the value of h represents the amount by which the function is shifted to the right.

__

The second attachment shows plots from my graphing tool for different values of k. As before, the red curve shows k=-2, the blue curve shows k=0, and the green curve shows k=1. Again, the upward zero crossing has been marked to show the effect. For k=-2, the curve is shifted down 2 units; for k=1, it is shifted up 1 unit. There is no shift when k=0.

You are intended to conclude that the value of k represents the amount by which the function is shifted upward.

__

If you do what the problem tells you to do, you can see these effects in real time, watching changes as they occur. You are expected to describe them. Only you know what the "vocabulary from 9/21-922" is.

Additional comment

Math instruction builds on previously seen concepts. This is not a subject in which you can be successful adopting the strategy of "test and forget." You're better off with a strategy of "learn it thoroughly and remember," working as many problems as necessary to keep it fresh in your mind.
