Answer:

Since you provided no graphs, I just graphed y=(x+3)(x+3). I hope this helps.

Final answer:

The graph defined by the function y = (x+3)(x+3) is a parabola opening upwards with its vertex at (-3, 0), represented by a U-shaped curve on the coordinate plane.

Explanation:

The function given by y = (x+3)(x+3) represents a quadratic equation, which can be expanded to y = x^2 + 6x + 9. This is a parabola that opens upwards because the coefficient of the x^2 term is positive. The graph of this function will have its vertex at the point (-3, 0), which is obtained by setting the inside of the parentheses to zero. To visualize this function, you would plot a series of points by choosing different values for x, calculate the corresponding y values, and then plot these points on a coordinate plane. Connecting these points will reveal the U-shaped curve typical for a quadratic function.

The value of Pascale's savings account at the end of the fifth year, with a 7.5% interest rate compounded annually and an additional $500 deposited each year, is approximately $3,122.00.

To calculate the value of Pascale's account at the end of the fifth year, we must use the compound interest formula which is A = P (1 + r)^t, where:

However, since Pascale deposits an additional $500 at the beginning of each year, the calculation is more complex than a single application of the formula. Our calculation should reflect the compound interest earned on each individual $500 deposit, not just the initial deposit.

Let's calculate the value at the end of year 5 step by step, adding $500 at the beginning of each year:

Therefore, the value of the account at the end of the fifth year is approximately $3,122.00.

Answer:

y = (-1/8)x^2

Step-by-step explanation:

Start with y = x^2.  When the original parabola has been reflected across the x-axis, the pertinent equation becomes y = -x^2.

Now if this is scaled vertically by a factor of 1/8, we get:

y = (-1/8)x^2

Answer:

( x + 3)² + ( y + 7)² = 361

Step-by-step explanation:

The equation of a circle written in standard form is ( x – h)² + ( y - k)² = r². The center is (h, k) and the radius is r.

With the given information of center (-3, -7) and radius 19, we get

[ x – (-3)]² + [ y - (-3)]² = (19)²

( x + 3)² + ( y + 7)² = 361

Answer:

The volume of the paper weight is 942.8 cubic cm.

Step-by-step explanation:

We are given the following in the question:

Dimensions of paperweight :

Radius, r = 10 cm

Height,h = 9 cm

Volume of paper weight = Volume of cone

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

where r is the radius and h is the height of the cone.

Putting values, we get,

[tex]V = \dfrac{1}{3}\times \dfrac{22}{7}\times (10)^2\times 9\\\\V = 942.8\text{ cubic cm}[/tex]

Thus, the volume of the paper weight is 942.8 cubic cm.

The volume is 942.5 [tex]cm^{3}[/tex].

To calculate the volume of a cone, you can use the formula:

V = (1/3)πr²h

where:

1. For Marta's paperweight with a radius of 10 centimeters and a height of 9 centimeters, you substitute the values into the formula as follows:

V = (1/3)π(10 cm)²(9 cm)

2. First, calculate the base area:

(10 cm)² = 100 cm²

3. Then, multiply by the height:

100 cm² × 9 cm = 900 cm³

4. Finally, multiply by (1/3)π:

V = (1/3)π × 900 cm³ ≈ 942.5 cm³

Therefore, the volume of the cone is approximately 942.5 [tex]cm^{3}[/tex], rounded to the nearest tenth.

Process

1.- Find the slope of the original line

    The slope is the coefficient of the x

                     y = 1/2x - 7

    slope = 1/2

2.- Find the slope of the new line

The new line is perpendicular to the original line

    slope = -2

3.- Find the equation of the new line

          y - y1 = m(x - x1)

          y - 7 = -2(x + 10)

-Simplification

Answer:

25%(1/4)

Step-by-step explanation:

The probability of getting tails on the first flip and heads on the second flip of a coin is 25%, as each flip is an independent event.

The question pertains to the probability of an event occurring in two successive trials - flipping a coin twice. Firstly, we need to recognize that each flip is an independent event. An independent event is one in which the outcome of the first event does not affect the outcome of the second. When you flip a coin, the probability of getting tails is 1/2 or 50%, and the probability of getting heads is also 1/2 or 50%. Since these are independent events, we multiply the probabilities to get the result.

When you multiply 1/2 (probability of getting tails on the first flip) by 1/2 (probability of getting heads on the second flip), your result is 1/4 or 25%.

So, the probability of getting tails on the first flip and heads on the second flip is 25%.

    a² = 64             a = 8

    b² = 25             b = 5

-Calculate c with the Pythagorean theorem

                   a² = b² + c²

-Solve for c

                   c² = a² - b²

-Substitution

                   c² = 8² - 5²

-Simplification

                  c² = 64 - 25

                  c² = 39

-Result

                  c = √13

4.- Find the center

          C = (0, 0)

5.- Find the vertices

          V1 = (-8, 0)     V2 = (8, 0)

6.- Find the foci

          F1 = (-√13, 0)   F2 = (√13, 0)

The center of the ellipse is (0,0), the vertices are (5.657, 0) and (-5.657, 0), and the foci are (3.317, 0) and (-3.317, 0).

The given equation of the ellipse is 25x^2 + 64y^2 = 1600.

To find the center of the ellipse, we can rewrite the equation in standard form: x^2/32 + y^2/25 = 1. The center is (0,0) since the x and y terms are squared and have the same coefficients.

To find the vertices of the ellipse, we can calculate the distance from the center to the major axis. The length of the major axis is 2*a, where a is the square root of the denominator of the x term. In this case, a = sqrt(32) ≈ 5.657. So the vertices are (5.657, 0) and (-5.657, 0).

To find the foci of the ellipse, we can calculate the distance from the center to the foci. The length of the foci is 2*c, where c is the square root of the difference between the squares of a and b (sqrt(32-25) ≈ 3.317). So the foci are (3.317, 0) and (-3.317, 0).

Answer:

Yes, it will overflow, because the volume of the scoop of ice cream is higher than the volume of the cone.

Step-by-step explanation:

To know if the cone will overflow when the entire scoop of frozen yogurt melts, we need to compare the volume of the scoop and the volume of the cone: if the volume of the scoop is higher, it will overflow.

The volume of the cone is:

V_cone = (1/3)*pi*r^2*h

Where V_cone is the volume, r is the radius and h is the height. So:

V_cone = (1/3)*pi*2^2*6 = 25.1327 in3

The volume of a sphere is:

V_sphere = (4/3)*pi*r^3

Where V_sphere is the volume and r is the radius. If the diameter is 4, the radius is 4/2 = 2. So:

V_sphere = (4/3)*pi*2^3 = 33.5103 in3

The volume of the sphere is higher, so the cone will overflow.

The volume of the melted ice cream scoop[tex](\( 33.51032 \, \text{cubic inches} \))[/tex] is greater than the volume of the cone [tex](\( 25.13272 \, \text{cubic inches} \))[/tex] the cone will overflow if the entire scoop of ice cream melts into it.

Step 1: Volume of the Cone

The formula for the volume of a cone is:

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

where [tex]\( r \)[/tex] is the radius and [tex]\( h \)[/tex] is the height.

Given:

[tex]\[r = 2 \, \text{inches}, \quad h = 6 \, \text{inches}\][/tex]

Substitute these values into the formula:

[tex]\[V_{\text{cone}} = \frac{1}{3} \pi (2)^2 (6)\][/tex]

[tex]\[V_{\text{cone}} = \frac{1}{3} \pi (4) (6)\][/tex]

[tex]\[V_{\text{cone}} = \frac{1}{3} \pi (24)\][/tex]

[tex]\[V_{\text{cone}} = 8 \pi \, \text{cubic inches}\][/tex]

Step 2: Volume of the Ice Cream Scoop

The formula for the volume of a sphere is:

[tex]\[V_{\text{sphere}} = \frac{4}{3} \pi r^3\][/tex]

where [tex]\( r \)[/tex] is the radius of the sphere.

Given that the diameter of the sphere is [tex]4\ inches[/tex], the radius [tex]\( r \)[/tex] is:

[tex]\[r = \frac{4}{2} = 2 \, \text{inches}\][/tex]

Substitute this value into the formula:

[tex]\[V_{\text{sphere}} = \frac{4}{3} \pi (2)^3\][/tex]

[tex]\[V_{\text{sphere}} = \frac{4}{3} \pi (8)\][/tex]

[tex]\[V_{\text{sphere}} = \frac{32}{3} \pi \, \text{cubic inches}\][/tex]

Step 3: Compare the Volumes

The volume of the cone:

[tex]\[V_{\text{cone}} = 8 \pi \, \text{cubic inches}\][/tex]

The volume of the ice cream scoop:

[tex]\[V_{\text{sphere}} = \frac{32}{3} \pi \, \text{cubic inches}\][/tex]

Let's convert them to decimal form for easier comparison:

[tex]\[V_{\text{cone}} = 8 \pi = 8 \times 3.14159 = 25.13272 \, \text{cubic inches}\][/tex]

[tex]\[V_{\text{sphere}} = \frac{32}{3} \pi = \frac{32}{3} \times 3.14159 = 33.51032 \, \text{cubic inches}\][/tex]

X = 3; P(X) = 0.25

X = 4; P(X) = 0.15

X = 5; P(X) = 0.05

Now expectation of number of emails that the manager would receive is given by X × P(X)

= 0 × 0.05 + 1 × 0.15 + 2 × 0.35 + 3 × 0.25 + 4 × 0.15 + 5 × 0.05
