The formula should be the same. most likely

Answer:

The length of the legs is 8.64cm and 14.64cm respectively

Step-by-step explanation:

I've added an attachment to aid my explanation.

At different intervals, I'll be making reference to it.

Given

[tex]AB = 17[/tex]

[tex]PAMC = 32[/tex]

[tex]PBMC = 25[/tex]

From the attachment, we have:

[tex]y + z = AB[/tex]

Since, M is the Midpoint

[tex]y = z = \½AB[/tex]

Substitute 17 for AB

[tex]y = z = \½ * 17[/tex]

[tex]y = z = 8.5[/tex]

Also, from the attachment

[tex]v + x + z = PAMC[/tex]

[tex]v + x + y = 32[/tex]

Substitute 8.5 for y

[tex]v + x + 8.5 = 32[/tex]

[tex]v + x = 32 - 8.5[/tex]

[tex]v + x = 23.5[/tex] --------- (1)

Also, from the attachment

[tex]v + w + z = 25[/tex]

Substitute 8.5 for z

[tex]v + w + 8.5 = 25[/tex]

[tex]v + w = 25 - 8.5[/tex]

[tex]v + w = 17.5[/tex] ----------- (2)

Subtract (2) from (1)

[tex]v - v + x - w = 23.5 - 17.5[/tex]

[tex]x - w = 6[/tex]

Make x the subject

[tex]x = 6 + w[/tex]

Apply Pythagoras Theorem:

We have that:

[tex]AB^2 = AC^2 + BC^2[/tex]

The above can be replaced with

[tex]17^2 = x^2 + w^2[/tex] (see attachment)

[tex]289 = x^2 + w^2[/tex]

Substitute 6 + w for x

[tex]289 = (6 + w)^2 + w^2[/tex]

[tex]289 = 36 + 12w + w^2 + w^2[/tex]

[tex]289 - 36 = 12w + 2w^2[/tex]

[tex]253 = 12w + 2w^2[/tex]

Reorder

[tex]2w^2 + 12w - 253 = 0[/tex]

Solve using quadratic equation:

[tex]w = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 2[/tex]

[tex]b = 12[/tex]

[tex]c = -253[/tex]

[tex]w = \frac{-12 \± \sqrt{12^2 - 4 * 2 * -253}}{2 * 2}[/tex]

[tex]w = \frac{-12 \± \sqrt{144 + 2024}}{4}[/tex]

[tex]w = \frac{-12 \± \sqrt{2168}}{4}[/tex]

[tex]w = \frac{-12 \± 46.56}{4}[/tex]

Split:

[tex]w = \frac{-12 + 46.56}{4}[/tex] or [tex]w = \frac{-12 - 46.56}{4}[/tex]

[tex]w = \frac{34.56}{4}[/tex] or [tex]w = \frac{-58.56}{4}[/tex]

[tex]w = 8.64[/tex] or [tex]w = -14.64[/tex]

But length can't be negative

So:

[tex]w = 8.64[/tex]

Recall that: [tex]x = 6 + w[/tex]

[tex]x = 6 + 8.64[/tex]

[tex]x = 14.64[/tex]

Hence, the length of the legs is 8.64cm and 14.64cm respectively

Answer:

420 miles

Step-by-step explanation:

1 inch is equal to 105 miles. The amount of inches between the two towns is 4, and 4 inches is 4 times the amount of inches in the scale. If the amount of inches is multiplied by 4, then the amount of miles should be multiplied by 4 too:

105 * 4 = 420

The actual distance is 420 miles.

Hope this helps :)

Answer:

y = 8x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Step-by-step explanation:

Answer:

X = 27 bags

Step-by-step explanation:

Given the following data;

Ratio of mulch to fertilizer = 1:6

Quantity of mulch = 4.5 bags

Let the quantity of fertilizer = x

Therefore,

1 mulch = 6 fertilizer

4.5 mulch = x fertilizer

Cross multiplying, we have

x = 6 * 4.5

x = 27

Therefore, if she uses 4.5 bags of mulch, then she should use 27 bags of fertilizer.

Answer:

The ratio of boys and girls =3:5

Let

The number of boys=3x

[tex]\therefore[/tex]Number of boys is 78.

The correct answer is (b) a bacteria culture triples in size every day describes a exponential function.

A relation is a function if it has only One y-value for each x-value.

The growth of a population, bacteria culture, or puppy can be modeled by an exponential function if the growth rate is proportional to the current size.

In other words, if the growth rate is constant, then the growth can be modeled by an exponential function.

Out of the three situations given, option (ii) is the only one that has a constant growth rate, since the bacteria culture triples in size every day. This means that the growth rate is constant at 200% per day.

Option (i) has a growth rate that is not constant but increases every year, so it is not best modeled by an exponential function.

Option (iii) also has a growth rate that is not constant, since the puppy grows by a fixed amount of 2 pounds every month regardless of its current weight.

Therefore, the correct answer is (b) a bacteria culture triples in size every day describes a exponential function.

Answer:

4). [tex]y<\frac{1}{2}x-4[/tex] (look at my explanation for how to graph)

5.) [tex]y<\frac{?}{?}x+?[/tex] (look at my explanation for how to get the correct numbers)

6.) [tex]x\geq 2[/tex] (look at my explanation for how to graph)

Step-by-step explanation:

Question 4:

    Solving for y:

First it's better if you solve for y then graph, it's easier that way.

[tex]x-2y>8\\-2y>-x+8\\y<\frac{1}{2}x-4[/tex]

As you might notice the greater than sign flipped, that doesn't always happen. It only happens when you are dividing by a negative number.

    Graphing the inequality:

When you start graphing you should always start by plotting the y-intercept. Which in this case it's [tex](0,-4)[/tex]. Then starting from that point you would go up 1 unit then right 2 units then plot the new point because the slope is [tex]\frac{1}{2}[/tex]. The 1 would be the up and down as for the 2 it will be the right and left. This goes up 1 and right 2 because it's positive. So you keep going creating new points as you go then when you reached the end of the graph you would go back to [tex](0,-4)[/tex] and do the opposite so you will do down 1 then left 2. When you run out of room you will have to draw a line, but be careful the line has to be dotted because the solid lines are used for the greater/less than or equal to signs. Then make sure to add arrows at each side of the dotted line to indicate that this line is infinite.

Question 5:

I'm very sorry but I can't see the picture since it's a bit blurry. So I'll try to explain how to write the inequality the best I can. So first we need to know the y-intercept it should be the point directly on the y-axis. Then find the slope by seeing how it gets to the next perfect point. I can tell you that the slope will be positive. Also for the sign it's dotted that means the sign is [tex]<[/tex]. So the inequality should look something like this [tex]y<\frac{?}{?}x+?[/tex]. Make sure you have the signs correct too don't change the ones I already put in.

Question 6:

For this one the inequality will look like this [tex]x\geq 2[/tex]. Then for the graph you will plot [tex](2,0)[/tex]. Then make a solid line that goes vertically since the only x-value is 3 the y-value will be changing without the x. Then for the shading you will shade the right side of the line.

Step-by-step explanation:

Answer:

Step-by-step explanation:

15x+5y=8-3x

18x+5y=8⇒eqn 1

15x+5y=20y

15x-15y=0⇒eqn 2

eqn 1 * 3

 54x + 15y=24⇒eqn 3

eqn 3 + eqn 2

69x=24

x=24/69=0.3478

eqn  1⇒

    5y=8-18(24/69)

     y=1.7391/5

     y=0.3478

The solution to the system of equations is (10/3, -2).

Two or more expressions with an equal sign are defined as an equation.

The given equations are 15x + 5y = 20 and y = 8-3x.

15x + 15y = 20

Substitute y = 8-3x into the above equation:

15x + 15(8-3x) = 20

15x + 120 - 45x = 20

45x - 15x = 120 - 20

30x = 100

x = 10/3

Substitute x = 10/3 in y = 8 - 3x:

y = 8 - 3 (10/3)

y = 8 - 10

y = -2

Hence, the solution to the system of equations is (10/3, -2).

Step-by-step explanation:

Answer:

No, the student did not check the solution to the derived equation in the original equation.

No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.

No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.

Step-by-step explanation:

just did on edge good luck!

The student is wrong in his answer to the equation

3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.

3/a + 2 - 3 - 4 = 1/a - 2.

3/a - 1/a = 3.

2/a = 3.

a/2 = 1/3.

a = 2/3.
