My basketball team plays four games per week. During the first four weeks, we lost all 16 of our games. During week 5, we won three games and lost one game, bringing us to 3 wins and 17 losses for the season so far. Each week after that, we win 3 games and lose 1 game. At the end of which week will my team have won at least 65% of its games total for the first time in the season?

The answers would most likely be A,C,and B from my calculations

Answer:

2

Step-by-step explanation:

We don't need to "solve" this to figure out the answer.

We need to recognize that the first equation given is that of an ellipse and the second equation given is that of a line.

A line and an ellipse in a coordinate system can have these outcomes:

1. They can intersect (touch) at 1 point

2. They can intersect at 2 points

3. Can't intersect at all

Thinking will make sense. So, the maximum number of possible solutions is 2.

Note: The number of points of intersection are the solutions as well

Answer:

a) $ 120

b) $ 53

Step-by-step explanation:

Cost of Bicycle paid by Jin = $173

Cost of Helmet = $ 19

Total amount paid by Jin = $173 + $19 = $192

This amount is 160% of what Stefan originally spent. Let the amount he originally spent was n, so we can write:

192 = 160% of n

192 = 1.6n

n = [tex]\frac{192}{1.6} = 120[/tex]

Thus, Stefan originally spent $120 for buying the bicycle and the helmet.

Profit which he made from this sale = $ 173 - $ 120 = $53

So he made $53 by selling Jin a bicycle and a helmet

To find the original cost Stefan spent, we calculate 160% of the original cost equal to the total selling price of $192. Divide $192 by 1.60 to find the original cost. Subtract this cost from $192 to find Stefan's profit.

The student's question pertains to calculating the original cost and the profit made from a sale. To solve this, we can set up an equation where 160% of the original cost (which we will call 'x') is equal to the total selling price of the bike and helmet, which is $173 for the bicycle and $19 for the helmet, adding up to $192.

This equation can be represented as 1.60x = $192. To find the original cost (x), divide the total cost by 1.60: x = $192 / 1.60. Calculating this gives us the original cost that Stefan spent.

To find the profit, we subtract the original cost from the total selling price. If x represents the original cost, then the profit is $192 - x. The step-by-step explanation helps the student understand how to set up and solve equations involving percentages, a key concept in mathematics related to business and personal finance.

Final answer:

The number 23.014 in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001), illustrating the value of each digit according to its place value.

Explanation:

Writing the number 23.014 in expanded form means expressing each digit according to its place value. Expanded form represents a number by showing the value of each digit. For the decimal number 23.014, we look at the place value of each digit: the digit in the tens place, the ones place, the tenths place (one place after the decimal), the hundredths place (two places after the decimal), and so on.

The correct expanded form for 23.014 is:
<(2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001)

This means:

The '2' is in the tens place, so it represents 2 x 10, or 20.

The '3' is in the ones place, so it represents 3 x 1, or 3.

The '0' is in the tenths place, but since it's 0, it adds no value (0 x 0.1 = 0).

The '1' is in the hundredths place, so it represents 1 x 0.01, or 0.01.

Finally, the '4' is in the thousandths place, so it represents 4 x 0.001, or 0.004.

Therefore, 23.014 written in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001).

I'm pretty sure that the answer to this question is B

Isolate “y” in one of the equations, then substitute it in the other equation. After you find x, put it in the isolated equation and you’ll find y value.

The value of x = 1 and y = 0.

Consider the given system of equation

4x - 2y = 4  ........(1)

6x - 4y = 6 ........(2)

Solve the system algebraically,

By using the elimination method,

Multiply equation (1) by 2, and we get,

(1) ⇒ 8x - 4y = 8 ............(3)

Subtract equation (2) from (3), we get,

8x - 4y - (6x - 4y) = 8 - 6

Simplifying the above equation, we get

8x - 4y - 6x + 4y = 2

8x - 6x = 2

⇒ x = 1

Substitute x = 1 in (1) and solve for y, we get,

⇒ 4x - 2y = 4

⇒ 4 (1) - 2y = 4

⇒ 2y = 4 - 4

⇒ 2y = 0

⇒ y = 0

Therefore, the value of x = 1 and y = 0.

[tex]y=2(x+2) ^ 2 + 2.[/tex]

Step-by-step explanation:

For a quadratic equation written in the general form [tex]y=ax ^ 2 + bx + c[/tex],

the x coordinate of its vertex is:

[tex]x = -\frac{b}{2a} = h[/tex]

Then this equation written in the form of vertex is:

[tex]y=a(x-h) ^ 2 + k.[/tex]

Where the point (h, k) is the vertex of the parabola.

In this case we have the equation

[tex]y=2x^2+8x+10[/tex]

Then the x coordinate of its vertex is:

[tex]x=-\frac{8}{2(2)}\\\\x= -2[/tex]

Therefore the y coordinate of its vertex is:

[tex]f(-2) = 2(-2)^2+8(-2)+10\\\\f(-2) = 2[/tex]

The vertice is (-2, 2)

Then

[tex]h=-2\\\\k = 2[/tex].

This equation written in the form of vertex is

[tex]y=2(x+2) ^ 2 + 2.[/tex]

Set up an equation:

Answer:

[tex]x\in(-\infty,\infty)[/tex]

Step-by-step explanation:

The given function is [tex]f(x)=5^x[/tex]

Domain is the set of x values for which the function is defined.

The function  [tex]f(x)=5^x[/tex] is an exponential function and for any real values of x, the function f(x) will be defined.

Therefore, we can conclude that the domain of the function is all real numbers.

In interval notation, the domain of f(x) is

[tex]x\in(-\infty,\infty)[/tex]

The domain of the function f(x) = 5^x is all real numbers.

The domain of the function f(x) = 5x is all real numbers. In exponential functions like this one, the domain is always the set of all real numbers. This means that there are no restrictions on the values that x can take. For example, you can plug in any real number into the function, such as 0, 1, -2, or 3.5, and the function will still output a valid value.

Answer:

16%

Step-by-step explanation:

To solve this we are using the standard growth equation:

[tex]y=a(1+b)^x[/tex]

Were

[tex]y[/tex] is the final value after [tex]x[/tex] years

[tex]a[/tex] is the initial value

[tex]b[/tex] is the growth factor (yearly rate of appreciation in our case) in decimal form

[tex]x[/tex] is the time in years

We know from our problem that gold coin appreciated in value from $200.00 to $475.00 in 6 years, so [tex]y=475[/tex], [tex]a=200[/tex], and [tex]x=6[/tex].

Let's replace the values in our equation and solve for [tex]b[/tex]:

[tex]y=a(1+b)^x[/tex]

[tex]475=200(1+b)^6[/tex]

[tex]\frac{475}{200} =(1+b)^6[/tex]

[tex]2.375=(1+b)^6[/tex]

[tex]\sqrt[6]{2.375} =\sqrt[6]{(1+b)^6}[/tex]

[tex]1+b=\sqrt[6]{2.375}[/tex]

[tex]b=\sqrt[6]{2.375}-1[/tex]

[tex]b=0.155[/tex]

which rounds to

[tex]b=0.16[/tex]

Since our appreciation rate is in decimal form, we need to multiply it by 100% to express it as percentage:

0.16*100% = 16%

We can conclude that the yearly appreciation rate of our gold coin is approximately 16%

Step-by-step explanation:

-13x = 25 [Divide by -13]

x = -1 12⁄13

13 is your divisor, which will be your denominator, and the numerator is your remainder. Since 13 goes into 25 ONCE, 1 gets multiplied by 13 to get 13, then deduct that from 25 to get your remainder of 12. This is where you start putting the pieces together as a mixed number. Then attach the negative because whenever you divide a positive by a negative, you get a negative:

Answer:

f(2) = 3

Step-by-step explanation:

We are given:

f(0) = 3

and

f(n+1) = -f(n) + 5

We have to find the value of f(2). In order to find f(2) we first have to find f(1)

f(n + 1) = - f(n) + 5

Using n = 0, we get:

f(0 + 1) = - f(0) + 5

f(1) = -f(0) + 5                                                     Using the value of f(0), we get

f(1) = -3 + 5 = 2

Now using n = 1 in the function, we get:

f(1 + 1) = - f(1) + 5                                               Using the value of f(1), we get

f(2) = -2+ 5

f(2) = 3

Thus the value of f(2) will be 3

I’m not sure either, but lets keep in touch because I do Acellus too, and Trigonometry. Give me a thanks so we can message

Trigonometry involves the study of angles and sides of triangles, where sine, cosine, and tangent are fundamental ratios used to solve problems. The Law of Sines and the Law of Cosines help calculate unknown lengths and angles in various types of triangles.

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right-angled triangles. Key concepts such as trigonometric ratios including sine, cosine, and tangent are fundamental in solving problems in trigonometry. When provided with a diagram like Figure 4.17 or Figure 5.27, one can determine the magnitudes of various components by applying these trigonometric principles.

For instance, if we know the angle and a side length adjacent to it, we can find the lengths of the unknown sides using functions such as cosine for the adjacent side or sine for the opposite side relative to the given angle. The Law of Sines and the Law of Cosines are also substantial tools in trigonometry, allowing us to calculate unknown lengths and angles in non-right triangles. Practicing these calculations with a calculator, as mentioned, helps familiarize oneself with the trigonometric functions and their inverses.
