Trayvon enters a competition to guess how many balls are in a barrel. Trayvon’s guess is 63 balls. The actual number of balls is 60. What is the percent error of Trayvon’s guess?

Answer:

38.4º

Step-by-step explanation:

Use Law of Cosines

c² = a² + b² - 2ab*cosC

12² = 17² + 19² - 2(17)(19)*CosC

Simplify

144 = 289 + 361 - 646 * cosC

144 = 650 - 646 * cosC

Subtract 650 from both sides

-506= -646 * cosC

Divide both sides by -646

0.7832817337 = cosC

Take the arcsin of 0.7832817337

38.4º = C

Cheaters Solution!!!

Instead of doing the math you could think it through.

Since FD is less than 17

∠E must be less than 45º

So the answer must be A. 38.4º

Answer:

400 times Greater

Step-by-step explanation:

8 x 10^4

10^4 = 10000

10000 x 8 = 80000

2 x 10^2

10^2 = 100

2 x 100 = 200

[tex]\frac{80000}{200}[/tex]= 400

The scale of the given line will be 4 which is the difference in the length between the two successive numbers.

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

The number line is given in the question.

The scale of the number line is the difference in the length between the two successive numbers.

According to the given number line,

Here numbers are 9, 13, 17, 21, 25, 29

So the difference in the length between the two successive numbers

⇒ 13 - 9 = 17 - 13 = 21 - 17 = 25 -21 = 29 - 25 = 4

Therefore, the scale of the given line will be 4.

Answer:

well it looks like as each week is going by the puppy is gaining less weight cause at first 5 is added and then 4 so maybe the next week 3 is added

Answer:

Yes, the relationship is proportional.

Step-by-step explanation:

So if you don't understand what proportional means, it means corresponding, the same, equal.

So when you look at a graph like this then ask yourself this, "is x a multiple of y?"

For example: Is 2 a multiple of 4? Yes! It is! That makes it proportional.

Is 3 a multiple of 9? Yes it is! 3, 6, 9.

Is 4 a multiple of 12? It is 4, 8, 12

Answer:

y = 4(x - 3)² - 5

Step-by-step explanation:

Given the vertex, (3, -5), and the other point, (4, -1):

Substitute these values into the vertex form of the quadratic equation:

y = a(x - h)² + k

where:

(h, k) = vertex

a = determines the direction of which the graph opens (if a > 1, the graph opens up; a < 1, the graph opens down). The value of a also determines the width of the parabola.  If 0 < a < 1, the graph will be wide; if a > 1, the graph will be narrow.

h = indicates a horizontal translation.

k = indicates a vertical translation.

Next, substitute the values of the vertex, (3, -5), and the other given point, (4, -1) into the vertex form and solve for the value of a:

y = a(x - h)² + k

-1 = a(4 - 3)² - 5

-1 = a( 1 )² - 5

-1 + 5 = a1 - 5 + 5

4 = a

Therefore, the equation of the given graph is: y = 4(x - 3)² - 5.  

Note:

If the  equation needs to be in standard form, ax² + bx + c, simply expand the binomial factors in the vertex form, and combine like terms.  Doing so will result in the following standard form: y = 4x² - 24x + 31.

Answer:

y = 3x/2 + 3

Step-by-step explanation:

First let's solve for y in the given equation

Subtract 3x from both sides

3x - 2y = -10

- 3x         - 3x

-2y = -3x - 10

Divde both sides by -2

-2y/-2 = (-3x - 10)/-2

y = 3x/2 + 5

The slop of the parallel equation will have to be 3/2

y = 3x/2 + b

Plug in the given coordinates

4 = 3(2)/2 + b

4 = 1 + b

Subtract 1 from both sides

4 = 1 + b

- 1.  - 1

b = 3

y = 3x/2 + 3

Step-by-step explanation: do I even need an explanation for simple multiplication?

Step-by-step explanation:

you only need to put the cans fire x and y into the equation and see, if the equation is still true.

for (7, -3) :

3×7 - 5×-3 = -13

21 + 15 = -13

36 = -13 wrong, no solution

for (-8, 2) :

3×-8 - 5×2 = -13

-24 - 10 = -13

-34 = -13 wrong, no solution

for (-6. -1) :

3×-6 - 5×-1 = -13

-18 + 5 = -13

-13 = -13 true, this is a solution

for (9, 8) :

3×9 - 5×8 = -13

27 - 40 = -13

-13 = -13 true, this is a solution
