Answer:

fourth graph in second pic

Step-by-step explanation:

first lets substitute points to see whether the graph increases or decreases

sooo

y = -2(2^0)

y = -2

(0, -2)

y = -2(2^1)

y = -4

(1, -4)

y = -2(2^2)

y = -2(4)

y = -8

(2, -8)

with these points we can tell that the graph is decreasing, since there is two graphs decreasing, we can use the points to see if the parabola lies on the points (i think its called parabola)

its the last graph. fourth graph on page 2

Using an exponential function, it is found that f(5.5) = 19.8.

An exponential function is a function in which the growth rate is a percentage, modeled by:

In which:

f(3.5) = 25 means that:

[tex]ab^{3.5} = 25[/tex]

[tex]a = \frac{25}{b^{3.5}}[/tex]

f(8.5) = 14 means that:

[tex]ab^{8.5} = 14[/tex]

Hence:

[tex]\frac{25}{b^{3.5}} \times b^{8.5} = 14[/tex]

[tex]25b^5 = 14[/tex]

[tex]b = \sqrt[5]{\frac{14}{25}}[/tex]

[tex]b = 0.89[/tex]

Answer:

[tex]\huge\boxed{\sf 22670.80 \ cm^3}[/tex]

Step-by-step explanation:

Height = h = 20 cm

Diameter = d = 38 cm

Radius = d / 2 = 38 / 2 = 19 cm

Volume of cylinder:

[tex]= \pi r^2 h\\\\= (3.14)(19)^2(20)\\\\= (3.14)(361)(20)\\\\= 22670.80 \ cm^3\\\\\rule[225]{225}{2}[/tex]

Solution:

Given:

First, let's find the radius of the cylinder as the radius of the cylinder is included in the formula.

[tex]\text{Diameter = 2(Radius)}[/tex]

[tex]\text{Radius} = \dfrac{\text{Diameter}}{2}[/tex]

[tex]\text{Radius} = \dfrac{38}{2}[/tex]

[tex]\text{Radius} = 19 \ \text{cm}[/tex]

Recall that the volume of a cylinder is πr²h. Now, let's use the formula to find the volume of the cylinder.

[tex]\pi r^{2} h = \text{Volume of cylinder}[/tex]

[tex](\pi)( r^{2})( h) = \text{Volume of cylinder}[/tex]

Answer: Si 3-3 \ 4 lb de dulces cuestan $ 20.25, ¿cuánto sería 1 lb de dulces

Step-by-step explanation:

Answer:

-11/3, -2.25, -3/2, 0.5

Step-by-step explanation:

A) The experimental probabilities are:

R = 0.45, B = 0.4, and Y = 0.15

From this, we can expect to get a red ball on the next draw.

B) This can happen because the experimental probabilities are bad estimations, or because the balls on the machine are not replaced.

A) The probability of getting each color will be given by the quotient of the number of balls of that color and the total number of balls.

For example, we know that 100 people buy gumballs, and 45 of them got red ones, so the experimental probability of getting a red gumball is:

R = 45/100 = 0.45

40 got a blue ball, so the probability of getting a blue ball is:

B = 40/100 = 0.4

15 got a yellow gumball, so the probability here is:

Y = 15/100 = 0.15

As you can see, the experimental probability of getting a red gumball is 3 times the probability of getting a yellow one. based on that, we can expect that the next gumball out from that machine will be red.

B) So now 10 more people go to the machine, and they get:

7 yellow, 1 red, and 2 blue gumballs.

This clearly does not follow the experimental probability we got above, why this may happen?

There are two main reasons.

First, to get a valuable experimental probability an experiment must be performed a lot of times, 100 is a ratter a small number. So the experimental probability that we got on point A may be a really bad estimation.

On another hand, there is a possibility that the gumballs in the machine are not being replaced. So initially, there is a fixed number of red, yellow, and blue balls.

This would mean that if we remove one red ball on the first try. Then for the next try, the probability of getting a red ball will be smaller (because now the machine has fewer red balls).

Then, because out of the 100 first balls most were red or blue, we can assume that most of the remaining balls on the machine are now yellow, and then the probability of getting a yellow ball is increased.

The area of the original garden is x^2 square feet.

The lengths of the sides of the new garden are x + 2 feet and x + 7 feet.

The area of the new garden, in square feet, is

[tex](x + 2)(x + 7)[/tex]

[tex] {x}^{2} + 9x + 14[/tex]

1) the area of his garden is, x² feet²

2) the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

And, the area of the new garden is,

Area = x² + 9x + 14

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Farmer Bob has a small square garden that is x feet by x feet.

Now,

We know that;

Area of square = Side²

Here, Side = x feet

Hence, the area of his garden is,

Area = x × x

Area = x² feet²

Now, When He decides to add 2 feet to one side of the garden and 7 feet to the other side.

Then, the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

Hence, the area of the new garden is,

Area = (x + 2) (x + 7)

Area = x² + 2x + 7x + 14

Area = x² + 9x + 14

Thus, 1) the area of his garden is, x² feet²

2) the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

And, the area of the new garden is,

Area = x² + 9x + 14

Cos95° = (15^2+13^2-a^2)/(2*15*13)

To dilate of the small triangle to get the large triangle the center of dilation is required

The description of the dilation is as follows;

Location of the center of dilation;

The coordinate of the center of dilation is given as follows;

[tex]\left( x_0 = \dfrac{k \cdot x_1 - x_2}{k - 1}, \ y_0 = \dfrac{k \cdot y_1 - y_2}{k - 1} \right)[/tex]

Where;

k = The scale factor of dilation

(x₁, y₁) = A coordinate point on the preimage

(x₂, y₂) = A coordinate point on the image

From the given drawing, we have;

Two vertices on the preimage are; (2, 0), and (5, 1)

Two corresponding vertices on the image are; (0, 0), and (9, 3)

Using the formula for length, l, we have;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

[tex]l_{small} = \sqrt{\left (1 -0 \right )^{2}+\left (5-2 \right )^{2}} = \sqrt{10}[/tex]

[tex]l_{large} = \sqrt{\left (9 -0 \right )^{2}+\left (3-0 \right )^{2}} = \sqrt{90} = 3 \cdot \sqrt{10}[/tex]

The steps to create the larger triangle from the center of dilation are as follows;

Alternatively larger triangle can also be created using the vertices as follows;

The coordinates of the third vertex of the small triangle are; (4, -2)

To obtain the coordinates of the large triangle, the coordinates of

the small triangle are multiplied by the scale factor, followed by adding the

coordinates of the center of dilation, we have that the coordinates of the

image are;  

[tex](k \times x_{ai} + x_0, \ k \times y_{ai} + y_0)[/tex]

Where;

[tex](x_{ai}, \ y_{ai})[/tex] = The difference between the coordinate values of the vertices of

the small triangle and the center of dilation, we have;

(2 - 3, 0 - 0) = (-1, 0)

(5 - 3, 1 - 0) = (2, 1)

(4 - 3, -2 - 0) = (1, -2)

We have [tex](k \times x_{ai} + x_0, \ k \times y_{ai} + y_0)[/tex] are;

(3 ×(-1) + 3, 3× 0 + 3) = (-3 + 3, 0) = (0, 0)

(3 × 2 + 3, 3 × 1 + 0) = (6 + 3, 3) = (9, 3)

(3 × 1, 3 × (-2) + 0) = (3 + 3, -6) = (6, -6)
