Answer:

She will pay more

Step-by-step explanation:

because if you multiply 19x12 you get 228 which is more than 190.

Miss Lacey will pay more than $190 for a year of gym membership because 12 months multiplied by $19 per month equals $228, which is greater than $190.

To determine if Miss Lacey will pay more or less than $190 for a year of gym membership, we need to calculate the total cost for one year. Since a year has 12 months, and the membership cost is $19 per month, we multiply the monthly cost by the number of months in a year:

Annual cost = $19 per month × 12 months

Therefore, the annual cost is:

$19 × 12 = $228

Comparing the annual cost to $190, we find that Miss Lacey will pay more than $190 for a year of gym membership, since $228 is greater than $190. This calculation exemplifies a straightforward mathematical operation involving multiplication and comparison.

Answer:

[tex]a_0 = -8[/tex]

[tex]a_1=-6[/tex]

[tex]x^2 +y^2 -8x - 6y = 0[/tex]

Step-by-step explanation:

The equation of the circle has the following form

[tex]x^2 + y^2 + a_0x + a_1y=0[/tex]

The equation of the circle has the following form

We know that the circle goes through the following points

(1, 7)

(8, 6)

(7, -1).

Then we substitute the values of x and y in the equation

For (1, 7)

[tex](1)^2 + (7)^2 + a_0(1) + a_1(7)=0[/tex]

[tex]1 + 49 + a_0 + 7a_1=0[/tex]

[tex]a_0 + 7a_1=-50[/tex]    (1)

For  (8, 6)

[tex](8)^2 + (6)^2 + a_0(8) + a_1(6)=0[/tex]

[tex]64 + 36 + 8a_0 + 6a_1=0[/tex]

[tex]8a_0 + 6a_1= -100[/tex]    (2)

With these equations is enough to solve the system

[tex]a_0 + 7a_1=-50[/tex]    (1)

[tex]8a_0 + 6a_1= -100[/tex]    (2)

Multiply the equation (1) by -8 and add it to the equation (2)

[tex]-8a_0 - 56a_1=400[/tex]    (1)

[tex]8a_0 + 6a_1= -100[/tex]    (2)

-----------------------------------------------------

[tex]-50a_1 = 300\\\\a_1 = -6[/tex]

Then

[tex]a_0 + 7(-6) = -50\\\\a_0 = -50+42\\\\a_0=-8[/tex]

Finally the equation is:

[tex]x^2 +y^2 -8x - 6y = 0[/tex]

Answer:

P (blue | black) = 0.151

Step-by-step explanation:

We know that there are 14 blue pens, 7 black pens and 5 red pens in Mrs. Johnson's desk drawer.

We are to find the probability of getting a blue pen and then a black pen when choosing two pens randomly without replacement.

Total pens = 14 + 7 + 5 = 26

P (blue pen) = 14/26

P (black pen) = 7/25

P (blue | black) = 14/26 * 7/25 = 49/325 or 0.151

Answer:  Option B

[tex]F (x) = x ^ 4-x ^ 2 + 4[/tex]

Step-by-step explanation:

We have the function [tex]G (x) = x ^ 4-x ^ 2[/tex] and we know that it contains the point (0,0). That is, it cuts the y axis and y = 0

Then the graph of F(x) is shown in the image and we know that it is a transformation of F(x).

The function F(x) cuts the y axis and y = 4.

For this reason we can conclude that the function F(x) is the function G(x) displaced 4 units upwards.

The transformation that shifts the graph of a function k units upwards is:

[tex]F (x) = G (x) + k[/tex]

Where [tex]k> 0[/tex].

In this case k = 4. Therefore:

[tex]F (x) = G (x) +4\\\\F (x) = x ^ 4-x ^ 2 + 4[/tex]

The answer is Option B

Answer:

y = (3/5)x + 3

Step-by-step explanation:

You can see immediately that the y-intercept is (0, 3).

As we go right from the point (-5, 0) to the point (0, 3), x increases by 5 and y increases by 3.  Thus, the slope of this line is m = rise / run = 3/5.

Starting with the generic y = mx + b, we get y = (3/5)x + 3.

Answer:

Y=3/2x-3

Step-by-step explanation:

3/2 is the slope. Remember, rise/run. so the rise is 3 and the run is 2. so up three since its positive and right 2 cuz its positive. and the -3 is the y inercept. hope this helps love :)

Answer:

The distance between two points is √169 or 13.

Step-by-step explanation:

In the question we need to find the distance between two points 5,6 and 0,-6 given.

Distance between two points can be found using the formula:

[tex]d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}[/tex]

Putting the given points in the formula we get,

x₂ = 0, x₁ = 5, y₂= -6, y₁= 6

[tex]=\sqrt{(0-(5))^2 + (-6-(6))^2} \\=\sqrt{(0-5)^2 + (-6-6)^2}\\=\sqrt{(-5)^2 + (-12)^2}\\=\sqrt{25 + 144}\\=\sqrt{169}\\=13[/tex]

So, the distance between two points is √169 or 13.

shipping cost $6 for a small box and $11 for a medium box

Step-by-step explanation:

The question is on formation of simultaneous equations

Anna shipped 10sb + 6mb =$126

Jeffrey shipped 5sb + 6mb=$96

Let small boxes,sb, be represented by x

Let medium boxes, mb, be represented by y

Equations

10x+6y=126------------------------(a)

5x+6y=96.......................................eliminate y by subtraction

5x=30.................................................divide by 5 to remain with x

x=30/5= 6......................................substitute value of x in equation (a)

(10×6) + 6y =126

60+6y=126

6y=126-60

6y=66..............................................divide by 6 both sides to get y

y=66/6= 11

Solution

x=6 and y=11

shipping cost $6 for a small box and $11 for a medium box

=(2x+3)(2x+3)

=(2x)(2x)+(2x)(3)+(3)(2x)+(3)(3)

=4x^2+6x+6x+9

=4x^2+12x+9

The standard form of the given quadratic equation y = (2x + 3)^2 is y = 4x^2 + 12x + 9. This is achieved by applying the square of a binomial rule and simplifying.

The given equation is y = (2x + 3)^2. This is in the form of a squared binomial, which can be expanded and simplified into a standard form of a quadratic equation. The standard form of a quadratic equation is y=ax^2 + bx + c.

To convert the given equation into standard form, we need to apply the square of a binomial rule, which states that (A + B)^2 = A^2 + 2AB + B^2. Here, A = 2x and B = 3.

So, we can rewrite the equation as follows: y = (2x)^2 + 2*2x*3 + 3^2 = 4x^2 + 12x + 9. Therefore, the standard form of the given quadratic equation is y = 4x^2 + 12x + 9.

For -4+2 you’d start at -4 then add two headed to the positive side

The sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The expression is given below.

⇒ -4 + 2 - 4 - 2

Firstly, subtract 4 from zero, then the line goes from zero to negative 4.

Secondly, add 2 from -4, then the line goes from negative 4 to -2.

Thirdly, subtract 4 from -2, then the line goes from negative 2 to -6.

And finally, subtract 2 from -6, then the line goes from negative 6 to -8.

Thus, the sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.

Answer:

The weight of the larger marble paperweight is 4.05 lb

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its weights (or volumes) is equal to the scale factor elevated to the cube

Remember that the scale factor is the ratio between corresponding sides

Let

z ------> the scale factor

x -----> the weight of the larger marble paperweight

y -----> the weight of the original marble paperweight

[tex]z^{3} =\frac{x}{y}[/tex]

In this problem we have

[tex]z=3[/tex]

[tex]y=0.15\ lb[/tex]

substitute and solve for x

[tex]3^{3} =\frac{x}{0.15}[/tex]

[tex]x=(27)(0.15)=4.05\ lb[/tex]

Volume of tissue box with 17 cm height and 8 cm side length base is 1088 cubic centimeters.

To find the volume of the tissue box, you can use the formula for the volume of a rectangular prism:

Volume = Base Area × Height

Since the base of the tissue box is a square, you can find the area of the base by squaring the side length:

Base Area = Side Length^2

Then, you multiply the base area by the height of the tissue box:

Volume = Base Area × Height

Let's plug in the values:

Side Length = 8 cm

Height = 17 cm

First, find the base area:

Base Area = 8 cm × 8 cm = 64 cm²

Then, calculate the volume:

Volume = 64 cm² × 17 cm = 1088 cm³

So, the volume of the tissue box is 1088 cubic centimeters.

The complete question is here:

A tissue box that has a height of 17 cm and that has a square base with a side length of 8 cm. What is the volume of a box of tissue?

Volume-πr^2h

r-11

h-15

11^2*15

=1815π

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is clear that the radius of the cylinder is 11 units and the height of the cylinder is 5 units.

The volume of the cylinder is

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

Where, r is radius and h is height.

Substitute x=11 and h=15 in the above formula.

[tex]V=\pi \times (11)^2\times (15)[/tex]

[tex]V=\pi \times 121\times (15)[/tex]

[tex]V=1815\pi[/tex]

The volume of the cylinder is 1815π unit³.

Therefore the correct option is C.

Answer:

250 cubic cm

Step-by-step explanation:

First step is to measure the volume of the rectangular prism... which is easy... it's the width * length * height.  Since we have a square base, the width and length are the same: 5 cm.  The volume is then: 5 * 5* 12 = 300 cubic cm.

The volume of a pyramid is obtained by the following formula:

V = (1/3) * base_area * height

We have the base area (5 * 5 = 25) and we have the height: 6 cm (half of 12 cm).

So, the volume of the pyramid is:

V = (1/3) * 25 * 6 = (1/3) * 150 = 50 cubic cm

The volume inside the prism but OUTSIDE the pyramid is then the volume of the prism (300 cubic cm) - the volume of the pyramid (50 cubic cm), so 250 cubic cm.
