Answer:

A=2πrh+2πr2=2·π·3.5·8+2·π·3.52≈252.89821cm²

The surface area is 214.305cm².

The surface area is the area of the outer covering of the object.

It is given that radius, r=3.5 cm, and height, h=8 cm.

The surface area of the given object will be the sum of curved surface area and the area of the bottom, which is circle.

Surface Area = Curved Surface Area + Area of bottom circle

=2πrh+πr²

=2π(3.5)(8)+π(3.5)²

=56π+12.25π

=68.25π

Substitute π=3.14 to determine the surface area.

Surface Area = 68.25(3.14)

=214.305

So, the surface area will be 214.305cm².

Probability is computed as follows:

When rolling a pair of six-sided dice, the total number of outcomes is 36 (= 6x6)

(a) number of favorable outcomes: 3 (dice: 1 and 3, 2 and 2, 3 and 1)

Then, the probability that the sum of the numbers on your dice is exactly 4 is:

(b) number of favorable outcomes: 1 (dice: 1 and 1)

Then, the probability that the sum of the numbers on your dice is at most 2 is:

(c) number of favorable outcomes: 1 (dice: 6 and 6)

Then, the probability that the sum of the numbers on your dice is at least 12 is:

Given:

the population size P(1) after t hours is given by the following exponential function:

Find the initial population size?

The initial size = 2000

Does the function represent growth or decay?

Growth, Because the initial value multiplied by a factor > 1

By what percent does the population size change each hour?

The factor of change = 1.09 - 1 = 0.09

So, the bacteria is increasing by a factor of 9% each hour

To find the cost of the goods after two years we are going to use the formula:

where P is the cost now, r is the inglation rate in decimal form, n is the number of times the interest is taken per year and t is the time.

In this case we have P=$300.00, r=0.07, n=1 (once per year) and t=2 (two years). Plugging this values we have:

Therefore after two years the cost will be $377.82

The slope of the line that passes through the points (-5,6) and (-9,-6) is m = 3

The first point = (-5,6)

The second point = (-9,-6)

The slope of the line defined as the change in y coordinates with respect to the change in x coordinates.

The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where m is the slope of the line

[tex](x_1,y_1)[/tex]  is the coordinates of the first point

[tex](x_2,y_2)[/tex] is the coordinates of the second point

Substitute the values in the equation

The slope of the line m = [tex]\frac{-6-6}{-9-(-5)}[/tex]

= -12/-4

= 3

Hence, the slope of the line that passes through the points (-5,6) and (-9,-6) is m = 3

Using the below equation

The height of the mountain is 2936.39 feet.

Given,

In the question:

The angle of elevation to the top of the mountain is 25°.

To find the height of the mountain, we can draw triangles as in the image attached.

Now, According to the question:

Let's call the height of the mountain 'h', and the distance from the first point (25degrees) to the mountain 'x'.

Then, we can use the tangent relation of the angles:

tan(29) = h/x

tan(25) = h/(x+1000)

tan(25) is equal to 0.4663, and tan(29) is equal to 0.5543, so:

h/x = 0.5543 -> x = h/0.5543

using this value of x in the second equation:

h/(x+1000) = 0.6009

h/(h/0.5543 + 1000) = 0.4663

h = 0.4663 * (h/0.5543 + 1000)

h = 0.8412h + 466.3

0.1588h = 466.3

h = 466.3 / 0.1588 = 2936.39 feet

Hence, the height of the mountain is 2936.39 feet.

hello

the question here is an equation and we are asked to solve for y

we'll follow some steps here

step 1

take y to the left side of the equation and bring 17 to the right hand side of the equation

note: the sign changes once they cross equality sign

step 2

divide both sides by the coeffiecient of y which is 2

from the calculations above, the value of y = (7x - 17)/2

6x - 9y - 7x + -6y

To simplify the expression add the like terms

The like terms are the terms which have the same variable and same degree

6x, -7x are like terms

-9y, -6y are like terms

So let us add them

(6x + -7x) + (-9y + -6y)

6 + -7 = -1

6x + -7x = -x

-9 + - 6 = -15

-9y + -6y = -15y

(6x + -7x) + (-9y + -6y) = -x + -15y
