Answer:

To find the value of the y units, u have to multiply any x unit with the first y unit given but not 0

Step-by-step explanation:

It could be anything from 450 - 549 so pick a number within those two (for example, 460, 499, 523, 538, all of those work)

When rounding to the nearest hundred, any whole number from 450 to 549 will round to 500. We consider the tens place in a number to decide whether to round up or down.

In the field of Mathematics, when we are rounding a whole number to the nearest hundred, we look at the tens place. If the tens digit is 5 or above, we round up. If it's 4 or below, we round down. So, any whole number ranging from 450 to 549 will round up or down to 500 when rounding to the nearest hundred. For example, numbers like 475, 500, 525, or 543.

Answer:

You need 30 total weeks to win at least 65% games

Step-by-step explanation:

Team have played = 20 games

Number of winning games = 3

Let x represents the number of additional weeks.

You have won 3 games per week. Therefore you will win 3x additional games.

We know that 65% = 0.65

Therefore,

3+3x/20+4x = 0.65

By cross multiplication:

3+3x= 0.65(20+4x)

3+3x = 13+2.6x

Combine the like terms:

3x-2.6x = 13-3

0.4x=10

4x/10 =10

4x = 10*10

4x=100

Divide both sides by 4

4x/4 = 100/4

x = 25

since you have already played 5 weeks...you need to play 25+5 = 30 weeks.

Therefore you need 30 total weeks to win at least 65% games....

Final answer:

To calculate Trevor's total investment, multiply the number of shares of each fund by their respective offer prices and sum the results. Trevor's total investment for both Upton Group and TJH Small-Cap amounts to $2850.30.

Explanation:

To calculate Trevor's total investment, we need to multiply the number of shares he purchased by their respective offer price and then add the costs of both investments together.

For the Upton Group, the investment is:

80 shares × $18.96 per share = $1516.80

For TJH Small-Cap, the investment is:

70 shares × $19.05 per share = $1333.50

Therefore, Trevor's total investment is:

$1516.80 (Upton Group) + $1333.50 (TJH Small-Cap) = $2850.30

A triangle with angles of 30, 60, and 90 degrees is a unique and special type of right triangle known as a 30-60-90 right triangle, which has consistent properties and side ratios in Euclidean geometry.

Yes, a triangle with angles of 30, 60, and 90 degrees is a unique triangle, known as a 30-60-90 right triangle. This classification is based on the fact that in Euclidean geometry, the sum of the angles in any triangle is exactly 180 degrees. Since one of the angles is given as 90 degrees, this indicates it is a right triangle, and the remaining angles must add up to 90 degrees. Given that the other two angles are 30 and 60 degrees, this satisfies the requirement exactly, making it a specific type of right triangle with consistent properties.

For example, the sides of a 30-60-90 triangle are always in the ratio 1:√3:2. The side opposite the 30-degree angle is the shortest; the side opposite the 60-degree angle is √3 times longer; and the hypotenuse, opposite the 90-degree angle, is twice as long as the shortest side. These proportions and the angles create the unique properties of the 30-60-90 triangle, and they can be applied in trigonometric calculations and proofs. This distinct set of angles and side ratios is what makes the 30-60-90 triangle a special and unique case in geometry.

Answer:

Discriminant = 16

Step-by-step explanation:

We have the following expression: -3 = -x^2 + 2x

Organizing the expression, we have: x^2 - 2x -3 = 0

We know that for an equation of the type: ax^2 + bx + c = 0, the discriminant is: b^2-4ac

From our equation we know that a=1, b=-2, and c=-3.

Then Discriminant = (-2)^2 - 4(1)(-3)

Discriminant = 4 +12 = 16

Step-by-step explanation:

This problem models a right triangles, where the hypothenuses is the length of the string, and one leg would be 180ft, which is the difference between the total height from the ground and the pole height (186-6=180). Also, the angle in front of the knowing leg is 60.

As, based on all given values, we can apply trigonometric reasons to the hypothenuse, which is L.

[tex]sin60=\frac{180}{L}\\ L=\frac{180}{sin60}\\ L=\frac{180}{\frac{\sqrt{3} }{2} }\\ L=\frac{360}{\sqrt{3}}=\frac{360}{1.7} \approx 211.8ft[/tex]

Graph A is the correct graph for the transformations shown in the function g(x)

Step-by-step explanation:

Within the function [tex]g(x)=\sqrt[3]{x+2} -4[/tex]

We can see two transformations occur from the parent function. The first is a slide along the x-axis and the second is a slide along the y-axis

Under the radicand we see that it is x+2. This means that the function has been shifted 2 units left from the parent function

As there is a -4 outside of the radicand, it would mean that the function has been shifted 4 units down as well.

This means that we are looking for a function centered around the point (-2,-4)

The graph of ∛(x) is shifted backwards by 2 units along the x - axis and then is shifted 4 units in the downward direction along the y - axis.

Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -

y = 4x⁴ + 3x³ + 2x² + 6x + 7

We have the function -

{∛(x)}  and {∛(x + 2) - 4}

We can write the functions as -

[tex]$x^{\frac{1}{3} }[/tex]

and

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

The graph of ∛(x) is shifted backwards by 2 units along the x - axis. Then it is shifted 4 units in the downward direction.

Therefore, the graph of ∛(x) is shifted backwards by 2 units along the x - axis and then is shifted 4 units in the downward direction along the y - axis.

Option D. LN=64 units

Step-by-step explanation:

step 1

Find the value of x

we know that

LN=LM+MN -----> equation A

we have

LN=12x+16

LM=10x+8

MN=5x-4

substitute the values in the equation A

12x+16=(10x+8)+(5x-4)

Solve for x

12x+16=15x+4

15x-12x=16-4

3x=12

x=4

step 2

Find the value of LN

LN=12x+16

LN=12(4)+16=64 units

The length of LN in units is 64 units

From the question, we are to determine the length of LN

In the given diagram

/LM/ = 10x + 8

/MN/ = 5x - 4

We can observe that

/LM/ + /MN/ = /LN/

From the given information,

/LN/ = 12x + 16

Therefore,

10x + 8 + 5x -4 = 12x + 16

Solving for x

15x +4 = 12x + 16

Then,

15x - 12x = 16 - 4

3x = 12

Thus,

x = 4

Then, substitute the value of x into LN = 12x + 16

LN = 12(4) + 16

LN = 48 + 16

LN = 64 units

Hence, the length of LN in units is 64 units

Answer:

400° F = 204.4° C

Step-by-step explanation:

We are given a temperature 400 degree in Fahrenheit and we are to convert in into another unit that is Centigrade (also known as Celsius).

We know that 0 degree Centigrade is equal to 32 Fahrenheit so we will use the following formula for conversion of units:

(32°F − 32) × 5/9 = 0°C

(400°F − 32) × 5/9 = 204.4° C

The mean weight of the three reserve players is found by rearranging the formula for calculating the mean, substituting known values, and solving the equation.

Given that the mean weight of all 12 players (nine players + three reserve players) is 188 pounds. Let's denote the missing weight of the three reserve players as 'x', 'y', and 'z'.

The formula to calculate mean is the sum of all the weights divided by the number of players. Here, mean weight equals (9*188 + x + y + z) / 12.

As we know that the mean weight is 188 pounds. We can substitute it back into the formula:
9*188 + x + y + z = 188 * 12.
This simplifies to x + y + z = 188 * 12 - 9 * 188.

We divide by 3 (since we are looking for the mean weight of three players): (x + y + z) / 3 = (188*12 - 9*188) / 3. Thus, the mean weight of the three reserve players can be found by solving this equation.

The answer is:

The center of the circle is the point (-9,-2) and the circle has a radius of 6 units.

To solve the problem, we need to use the given equation which is in the general form, and then, use it transform it to the standard form in order to find the center of the circle and its radius.

So,

We are given the circle:

[tex]x^{2}+y^{2}+18x+4y+49=0[/tex]

We know that a circle can be written in the following form:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Where,

h is the x-coordinate of the center of the circle

k is the y-coordinate of the center of the circle

r is the radius of the circle.

So, to find the center and the radius, we need to perform the following steps:

- Moving the constant to the other side of the equation:

[tex]x^{2}+y^{2}+18x+4y=-49[/tex]

- Grouping the terms (x and y):

[tex]x^{2}+18x+y^{2}+4y=-49[/tex]

- Completing squares for both variables, we have:

We need to sum to each side of the equation the following term:

[tex](\frac{b}{2})^{2}[/tex]

Where, b, for this case, will the coefficients for both terms that have linear variables (x and y)

So, the variable "x", we have:

[tex]x^{2} +18x[/tex]

Where,

[tex]b=18[/tex]

Then,

[tex](\frac{18}{2})^{2}=(9)^{2}=81[/tex]

So, we need to add the number 81 to each side of the circle equation.

Now, for the variable "y", we have:

[tex]y^{2} +4y[/tex]

Where,

[tex]b=4[/tex]

[tex](\frac{4}{2})^{2}=(2)^{2}=4[/tex]

So, we need to add the number 4 to each side of the circle equation.

Therefore, we have:

[tex](x^{2}+18x+81)+(y^{2}+4y+4)=-49+81+4[/tex]

Then, factoring, we have that the expression will be:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

- Writing the standard form of the circle:

Now,  from the simplified expression (after factoring), we can write the circle in the standard form:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

Is also equal to:

[tex](x-(-9))^{2}+(y-(-2))^{2}=36[/tex]

Where,

[tex]h=-9\\k=-2\\r=\sqrt{36}=6[/tex]

Hence, the center of the circle is the point (-9,-2) and the circle has a radius of 6 units.

Answer:

Part A. the x-intercepts are: x=4 and x= -1/4

Part B. The vertex of the graph is going to be a maximum

Part C. y-intercept is y=8

Step-by-step explanation:

We have the following function:

f(x) = −8x^2 + 30x + 8

Part A: What are the x-intercepts (zeros) of the graph of the f(x)?

To find the x-intercepts we have to make y=0 and solve for x. Then:

y = −8x^2 + 30x + 8

0 = −8x^2 + 30x + 8

8x^2 - 30x - 8  = 0

Dividing the whole expression by 8:

x^2 - 15/4x - 1  = 0

Using the quadratic formula we have that:

(x−4)(4x+1)

So the x-intercepts are: x=4 and x= -1/4

Part B.  Is the vertex of the graph of f(x) going to be a maximum or minimum?

The vertex of the graph is going to be a maximum, given that the quadratic term is multiplied by a negative sign.

PArt C. What is the y intercept of the graph?

To calculate the y-intercept we need to make x=0, so:

y = −8(0)^2 + 30(0) + 8 = 8

So the y-intercept is y=8

Step-by-step explanation:

we know that

The volume of the figure is equal to the volume of the cone minus the volume of the square pyramid

step 1

Find the volume of the cone

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

we have

[tex]r=\frac{l\sqrt{2}}{2}\ units[/tex] ----> the diagonal of the square base of pyramid is equal to the diameter of the cone

[tex]h=l\ units[/tex]

substitute

[tex]V=\frac{1}{3}\pi (\frac{l\sqrt{2}}{2})^{2}(l)[/tex]

[tex]V=\frac{1}{6}\pi (l)^{3}\ units^{3}[/tex]  

step 2

Find the volume of the square pyramid

The volume of the pyramid is equal to

[tex]V=\frac{1}{3}Bh[/tex]

where

B is the area of the base

h is the height of the pyramid

we have

[tex]h=l\ units[/tex]

[tex]B=l^{2}\ units^{2}[/tex]

substitute

[tex]V=\frac{1}{3}l^{2}(l)[/tex]

[tex]V=\frac{1}{3}l^{3}\ units^{3}[/tex]

step 3

Find the volume of the figure
