Your grade point average is 3.48.How can you write the point average as a fraction

The discount is $37.50 and the sale price of the table is $212.50.

We have to calculate the discount and sale price

Discount

Discount amount =

Original price * Discount percentage

Discount amount = $250 * 15%

= $250 * 0.15

= $37.50

Sale price

Sale price = Original price - Discount amount

Sale price = $250 - $37.50

= $212.50

A full circle is 360 degrees.

The circle is separated into 8 parts, so each arc is 1/8 of a circle, which equals: 360/8 = 45 degrees.

There are 2 45 degree arcs between B and C, so the arc from B to C = 45 x 2 = 90 degrees.

The answer is B.

The square root of 128, which is an irrational number, is approximately 11.304. Rounded to two decimal places, it becomes 11.30.

The process of simplifying the irrational number 128 involves finding a square root since irrational numbers are those that cannot be expressed as a simple fraction, such as roots that are not even. The square root of 128 is not a whole number, therefore it's an irrational number. Using a calculator, the square root of 128 is approximately 11.304. So to obtain the square root of 128 to two decimal places, you round 11.304 to 11.30.

Answer:

Option c

Step-by-step explanation:

We have two matrices, matrix A and matrix B.

Before doing the addition of matrices, we must multiply the matrix A by the scalar -7 and then multiply the matrix B by the scalar -6.

The multiplication of a matrix A by a scalar c, is done by multiplying all the elements of matrix A by the value c.

So

[tex]-7A = \left[\begin{array}{ccc}70&-70&-56\\14&7&-35\\28&-56&42\end{array}\right]\\\\\\-6B =\left[\begin{array}{ccc}-30&-36&24\\-60&36&60\\54&-6&-60\end{array}\right][/tex]

Now we add both matrices.

The sum of the matrices is done by adding each term [tex]a_{mn}[/tex] with each term [tex]b_{mn}[/tex]

For example: (70 - 40) , (-70 + (-36)), ...,    

Then:

Answer:

f(x)=x^2+4x-5

Step-by-step explanation:

Quadratic functions are second-order polynomials. To solve a quadratic equation, set the function equal to zero, and use the quadratic formula. The corresponding polynomial function in this case is f(x) = x² + 5x - 1.

Quadratic functions are second-order polynomials. They are of the form f(x) = ax² + bx + c, where a, b, and c are constants. To solve a quadratic equation, set the function equal to zero, and use the quadratic formula: x = (-b ± √(b²-4ac))/(2a). The discriminant, b²-4ac, determines the number and nature of the solutions. If the discriminant is positive, there are two real solutions. If it is zero, there is one real solution (a perfect square). If it is negative, there are no real solutions, but there are two complex solutions.

In this case, the corresponding polynomial function is f(x) = x² + 5x - 1.

ANSWER

-7

EXPLANATION

The only numbers that have a distance of 7 from zero on the real number line are -7 and 7.

-7 is to the left of zero while 7 is to the right of zero.

But this two numbers are all 7 units from zero.

In other words, the absolute values of this numbers is 7.

[tex] |x| = 7[/tex]

[tex]x = - 7 \: or \: 7[/tex]

Hence the number Renee wrote is -7

The number that is the same distance from 0 as 7 on a number line, but in the opposite direction, is -7. This is because on a number line, +7 is 7 units to the right of 0 and -7 is 7 units to the left of 0.

In the field of Mathematics, the concept of a number line is a tool to understand the placement of numbers and their relative distance to one another. If Renee writes a number that is the same distance from 0 as 7 on a number line, but in the opposite direction, the number she writes would be -7.

This is because on a number line, the positive direction (to the right) signifies adding and the negative direction (to the left) signifies subtracting from zero. So the number -7 is 7 units distance to the left of 0. Similarly, the number 7 is 7 units distance to the right of 0. Hence, both numbers -7 and +7 are equidistant from 0, but lie in opposite directions on the number line.

Step-by-step explanation:

volume of the cylinder= pi r^2 h

=22/7*3*3*5=141.428

nearest hundredth =141.420

volume of the given cylinder= 141.42 cubic feet

Answer:

The volume of the cylinder is 141.43 ft³.

Step-by-step explanation:

Since, the volume of a cylinder is,

[tex]V=\pi (r)^2 h[/tex]

Where, r is the radius of the cylinder,

And, h is the height of the cylinder,

Here, r = 3 feet,

h = 5 feet,

Hence, the volume of the given cylinder is,

[tex]V=\pi (3)^2 (5)[/tex]

[tex]=\frac{22}{7}\times 9\times 5[/tex]     (  [tex]\pi =\frac{22}{7}[/tex] )

[tex]=\frac{990}{7}[/tex]

[tex]=141.428571429\text{ cube feet}=141.43\text{ cube feet}[/tex]

x + x +1 + x +2 + x + 3 >= 244

=》 4x + 6 >= 244

=》 4x >= 238

=》 x >= 238/4 >= 59.5

since x is an integer...least value of x is 60

The least possible even integer is 58

Let's let x be an even integer. The next three would be shown by x+2, x+4 x+6 so now we can add all these to equal 244. Shown with an equation would look like:

x + x+2 + x+4 + x+6 = 244

Combine like terms will be:

4x+12=244

Subtract 12 from both sides we will get

4x=232

Now Divide each side by 4

x=58

So now put x in the above equation and we get  the numbers

x=58,

x+2= 60

X+4 =62

x+6= 64

The least one is 58

Answer:

Option A

Step-by-step explanation:

A relation can be defined as a function if there is only one output for each input.

In this case, the output is the cost of the fabric and the input is the number of yards of fabric.

Then, for each number of yards of fabric there will be a cost. But there will not be two different costs (outputs) for the same number of fabric yards (entrance)

Then the answer is the Option A: Yes, because one imput (number of yards of fabric) will always have the same output (costs)

For this case we must find the area of a scalene triangle (different sides) by means of Heron's formula:

[tex]S = \sqrt {p (p-a) (p-b) (p-c)}[/tex]

Where:

S: It's the area

p: It is the semiperimeter

a, b, c: They are the sides:

[tex]p = \frac {a + b + c} {2}\\p = \frac {25 + 13 + 17} {2}\\p = 27.5 \ units[/tex]

So:

[tex]S = \sqrt {27.5 (27.5-25) (27.5-13) (27.5-17)}\\S = \sqrt {10467.1875}\\S = 102.309 \ units ^ 2[/tex]

For a system of 2 equations in 2 unknowns, there are 3 cases:

When slopes are different, the two lines intersect at one point, the solution.

When slopes are the same, the lines may be either parallel (different y-intercepts) or the same (same y-intercepts). If the lines are parallel, there are no points of intersection, hence no solutions. If the lines are the same line, they intersect at all points, so there are infinitely many solutions.

Answer:

Choice D is correct

Step-by-step explanation:

The eccentricity of the conic section is 1, implying we are looking at a parabola. Parabolas are the only conic sections with an eccentricity of 1.

Next, the directrix of this parabola is located at x = 4. This implies that the parabola opens towards the left and thus the denominator of its polar equation contains a positive cosine function.

Finally, the value of k in the numerator is simply the product of the eccentricity and the absolute value of the directrix;

k = 1*4 = 4

This polar equation is given by alternative D.

Answer:

The weight of the parcel is approximately 6 kilograms.

Step-by-step explanation:

The weight of the parcel is  12 lbs and 8 oz.

1 lb = 16 oz

So,  8 oz =  lb.

That means,  12 lbs and 8 oz = (12 + 0.5) lbs = 12.5 lbs

Now, 1 lb = 454 g

So,  12.5 lbs = (12.5 × 454) g = 5675 g

As,  1 kilogram = 1000 g

That means, 1 g = 0.001 kilogram

So,  5675 g  kilograms. (Rounded to the nearest whole kilogram)

Thus, the weight of the parcel is approximately 6 kilograms.

Answer:

40 feet

Step-by-step explanation:

The perimeter of a triangle is the distance around the triangle. It can be found by adding all the sides together. First, find the amount each side is by substituting x = 4 and simplifying.

3x - 4 = 3(4) - 4 = 12 - 4 = 8

x² -1 = (4)² - 1 = 16 - 1 = 15

2x² - 15 = 2(4)² - 15 = 32 - 15 = 17

Add the sides together, 8 + 15 + 17 = 40 feet

Answer:

f is not  defined at x = 3 ⇒ answer (b)

Step-by-step explanation:

∵ f(x) = x² - x - 6/x² - 9 is a rational function

∴ It will be undefined at the values of x of the denominator

∵ The denominator is x² - 9

∵ x² - 9 = 0 ⇒ x² = 9 ⇒ x = ±√9

∴ x = ± 3

∴ f(x) can not be defined at x = 3

∴ The f(x) can not be continuous at x = 3

∴ The answer is (b)

Answer:

b. f is not defined at x=3

Step-by-step explanation:

The given function is

[tex]f(x)=\frac{x^2-x-6}{x^2-9}[/tex]

One of the conditions for continuity is that; the function must be defined at [tex]x=a[/tex]

If we plug in [tex]x=3[/tex], we obtain;

[tex]f(x)=\frac{3^2-3-6}{3^2-9}[/tex]

[tex]f(x)=\frac{9-3-6}{9-9}[/tex]

[tex]f(x)=\frac{0}{0}[/tex]

Since the function is not defined at x=3, it is not also continuous at x=3

The correct choice is B

=============================================

Explanation:

Start with the first equation. We'll plug in y = 2x+2

3x - y = 3

3x - ( y ) = 3

3x - ( 2x+2 ) = 3 ..... replace y with 2x+2

3x - 2x - 2 = 3 ..... distribute the negative through to all terms inside

x-2 = 3  ............ combine like terms

x-2+2 = 3+2 .... add 2 to both sides

x = 5

Use this x value to find the value of y. The easiest equation to use is the one in which y is already isolated for us

y = 2x+2

y = 2*5+2 ..... replace x with 5

y = 10+2

y = 12

Though we can use the other equation as well

3x-y = 3

3*5-y = 3 .... replace x with 5

15 - y = 3

15-y-15 = 3-15 ..... subtract 15 from both sides

-y = -12

y = 12 ..... multiply both sides by -1, or change the signs of both sides

We get the same result for y.

The solution is (x,y) = (5,12) meaning that the graphs of the two original equations cross at this point.

It’s 5 & 12. Just substitute them in and boom!

Answer:

we know that

Using proportion

[tex]\frac{4}{8}\frac{days}{necklaces} =\frac{x}{1}\frac{days}{necklace} \\ \\x=4/8\\ \\x=0.5\ days[/tex]

You can see that each term is twice the previous one, with inverted sign.

You double a number by multiplying it by two, and you change its sign by multiplying it by -1.

So, you multiply each term by 2 and by -1, which results in a multiplication by -2.

Since we start with 3, the terms are

[tex]a_1 = 3[/tex]

[tex]a_2 = 3\cdot (-2) = -6[/tex]

[tex]a_3 = -6\cdot (-2) = 12[/tex]

and so on. So, the general term is

In the context of the problem, the zeros of the function represent the points in time when the roller coaster is at ground level. Specifically, the roller coaster goes underground at t = 5 seconds and comes back above ground at t = 8 seconds.

In the function f(t) = (t^2 − 13t + 40)(t^2 − 2t + 3), which models the height of the roller coaster above the ground, the zeros represent the points in time when the roller coaster is at ground level. In other words, when f(t) = 0, the height of the roller coaster is zero, implying it is at ground level. In your case, the zeros you found signify that the coaster is on the ground at the time instances t = 5 and t = 8 seconds since passing point A.

The values t = 5 and t = 8 seconds are the time instances when the roller coaster enters and exits the underground portion of the track respectively. It's crucial to comprehend the physical significance of mathematical solutions, particularly in real-world scenarios.
