Please help!!! How do I turn these problems into inequalities?!?!

Answer:

[tex]x = - 4 \: or \: x = - 14[/tex]

Step-by-step explanation:

We have been given the equation

[tex](x + 9) {}^{2} = 25[/tex]

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

[tex] \sqrt{(x + 9) {}^{2} } = \sqrt{25} [/tex]

[tex]x + 9 = \: 15[/tex]

[tex]x + 9 = 5 \: or \: x + 9 = - 5[/tex]

[tex]x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 = - 5 - 9[/tex]

[tex]x = - 4 \: or \: x = - 14[/tex]

THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION

[tex]x + 9 = 5 \: then \: x = - 4. \\ x + 9 = - 5 \: then \: x = - 14[/tex]

Answer:

Step-by-step explanation:

Given the radius and length of a side of regular octagon as shown;

radius = 6ft and length of side = 4.6ft

Area of a regular octagon is expressed as [tex]A = 2(1+\sqrt{2} )a^{2}[/tex] where a is the length of one side. Given a = 4.6ft

Area = [tex]A = 2(1+\sqrt{2} )(4.6)^{2}\\[/tex]

[tex]= 2(1+\sqrt{2} )*21.16\\= (2+2\sqrt{2})*21.16\\ = 4.83*21.16\\= 102.20ft^{2} \\[/tex]

Area of the regular octagon is approximately 102ft²

The approximate area of a regular octagon with a radius of 6 ft and a side length of 4.6 ft is about 110 ft², found using the area formula for regular polygons.

To approximate the area of a regular octagon, one can break it down into triangles or use a formula. In this case, let's use the formula for the area of a regular polygon, which is: A = (1/2) × Perimeter × Apothem. The apothem can be found using trigonometry since we have a regular octagon, or we could calculate the area as eight identical isosceles triangles, where each triangle's area is (1/2) × base × height.

The student has provided that the side length (s) is 4.6 ft. For a regular octagon, we have 8 such sides. Therefore, the perimeter (P) is P = 8s = 8  imes 4.6 ft = 36.8 ft. Assuming the radius given is the apothem, we can directly calculate the area using the formula:

A = (1/2) × P × Apothem = (1/2) × 36.8 ft × 6 ft = 110.4 ft².

The approximate area of the octagon is therefore about 110 ft², after rounding off to the nearest whole number (due to the significant figures rule).

Answer:

31.416

Step-by-step explanation:

2 times Pi (3.14) times the radius (5)

The radius into the formula gives a circumference of 10π feet.

The circumference of a circle can be calculated using the formula:

Circumference = 2 x π x radius

Given that the radius of the circle is 5 feet, we can substitute this value into the formula to find the circumference:

Circumference = 2 x π x 5 = 10π feet

Therefore, the circumference of the circle is 10π feet.

Final answer:

The measure of angle RSM is calculated to be 45 degrees.

Explanation:

The problem involves a triangle RSM where angle SRM is twice the measure of angle RSM, and a point O on side RS such that SO=SM.

Given that the length of the angle bisector of angle RMS equals RO, we seek to determine the measure of angle RSM.

Since the problem is based on the properties of triangles and angle bisectors, and it does not provide enough information to use standard geometric methods, we infer that the triangle RSM must be an isosceles triangle.

This is because SO=SM, which implies that angles RSM and RMS are equal.

Since SRM is twice RSM and the sum of angles in a triangle is 180 degrees, we can set up the equation

2x + x + x = 180,

where x is the measure of angle RSM.

Solving, we get 4x = 180, so x = 45 degrees.

Therefore, the measure of angle RSM is 45 degrees.

Answer:

area = 6[tex]\sqrt{14}[/tex]  units²

Step-by-step explanation:

Given the 3 sides of a triangle, we can use Hero's formula to calculate the area (A)

A = [tex]\sqrt{s(s-a)(s-b(s-c)}[/tex]

where s s the semi perimeter and a, b , c the sides of the triangle

let a = 5, b = 9 and c = 10

s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{5+9+10}{2}[/tex] = [tex]\frac{24}{2}[/tex] = 12

A = [tex]\sqrt{12(12-5)(12-9)(12-10)}[/tex]

   = [tex]\sqrt{12(7)(3)(2)}[/tex]

   = [tex]\sqrt{504}[/tex]

   = [tex]\sqrt{36(14)}[/tex]

   =  6[tex]\sqrt{14}[/tex] units²

Answer:

Step-by-step explanation:

a = 5 units ; b = 9units ; c = 10 units

Semi perimeter = (a+b+c)/2 = (5+9+10)/2 = 24/2 = 12 units

s-a = 12 -5 = 7 units

s -b = 12 - 9 = 3 units

s-c = 12- 10 =2 units

[tex]Area=\sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{12*7*3*2}\\\\=\sqrt{2*2*3*7*3*2}\\\\=2*3\sqrt{2*7}\\\\=6\sqrt{14}\\[/tex]

Step-by-step explanation:

I got it right

The point (-4, -4) does not satisfy the inequality y > -6x – 1, therefore it is not a solution to the inequation.

To determine whether the point (-4, -4) is a solution to the inequality y > -6x – 1, we need to substitute the points into the inequality and see if they satisfy it.

We replace y with -4 and x with -4 in the given inequality:

-4 > -6*(-4) -1

-4 > 24 - 1

-4 > 23

As we observe, the inequality is not satisfied. Thus, the point (-4, -4) is not a solution of the inequality y > -6x – 1.

Final answer:

To find the diameter of the base of the cylinder, use the formula for the volume to solve for the radius, then double the radius to find the diameter.

Explanation:

To find the diameter of the base of the cylinder, we need to first find the radius. We can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. Rearranging the formula to solve for the radius, we have r = √(V/πh).

Plugging in the given values: V = 63.6 cubic inches and h = 9 inches, we can find the radius: r = √(63.6/3.142 x 9).

Calculating the values: r ≈ √(20.2649) ≈ 4.5055 inches. The diameter is twice the radius, so the diameter ≈ 2 x 4.5055 ≈ 9.011 inches.

Answer:

When x is 4, y = 29

Step-by-step explanation:

the equation y = 5 + 6x, states that y equals 5 + 6 TIMES whatever x is.

So if x = 4, then you can substitute x in the equation to get this:

Y = 5 + 6(4) - substitute x with 4

Y = 5 + 24 - multiply 6 by 4  [6 + 6 + 6 + 6 = 6 x 4]

Y = 5 + 24 - add 5 and 24 together

Y = 29 - 5 + 24 = 29

Therefore, Y = 29

The probability that none of the chosen cards were spades is 27/64.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A student draws three cards from a standard deck of cards. If the student replaces the card after each draw.

Number of spades card = 13

The number of non-spade cards would be 39

The probability that none of the chosen cards were spades = Number of favorable outcomes / total number of outcomes

=  27/64.

Thus, The probability that none of the chosen cards were spades is 27/64.

Answer:

The Answer is : D

Step-by-step explanation:

First find the slope of the line that the equation should be parallel to. In this case it is 2/1 which simplified is 2.

Next insert the X (4) of the point (4,1) and solve to see if you get the Y(1).

y-1 = 2 (4-4)

y-1= 2 (0)

y-1= 0

y= 1

In this case D is correct.

TIP*

If you see the question ask you about a parallel formula, look at the slopes of them to see if they match up. Parallel formulas have the same slope, just a tip because you can see in the answer choices none of the equations have the same slope as the line on the graph except for D.

[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]

Step-by-step explanation:

When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:

since our system of equations is:

[tex]3x-5y=12\\ 4x-2y=15[/tex]

we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:

[tex]\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right][/tex]

Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:

[tex]\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right][/tex]

Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:

[tex]\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right][/tex]

usually there is a line separating the columns for the values of x and y, and the independent values:

[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]

this is the matrix of the system of equations

Step-by-step explanation:

Answer:

1) 1.4%

2) 8.3%

3) 20.8%

Step-by-step explanation:

Alrighty! You are looking at some compound probability problems.

The trick with these is to figure out the probability of each piece of an event, and then multiply those together to get the overall probability.

Quick note about notation: p(event A) is short hand for saying "The probability of event A is....."

1) Flipping head, rolling a 5, and rolling a 2

P(flipping heads) = 1/2

p(rolling a 5) = 1/6

p(rolling a 2) = 1/6

so: (1/2) x (1/6) x (1/6) = 1/72 or about 1.4%

2) Flipping tails, rolling an odd number, and rolling a 4

p(flipping tails) = 1/2

p(rolling an odd number) = 3/6

p(rolling a 4) = 1/6

so: (1/2) x (3/6) x (1/6) = 3/72 or about 8.3%

3) Flipping head, not rolling a 2, and rolling an even number

p(flipping heads) = 1/2

p(not rolling a 2) = 5/6

p(rolling and even number) = 3/6

so: (1/2) x (5/6) x (3/6) = 15/72 or about 20.8%
