Answer:

not a function it's a relation

Step-by-step explanation:

Answer:

The vertex angle is 94 degrees

Step-by-step explanation:

Let the vertex angle be x

Mathematically, the base angles of an isosceles triangle are the same

So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too

Mathematically, the sum of angles in a triangle is 180 degrees

Thus;

43 + 43 + x = 180

x = 180-86

x = 94 degrees

Answer:

I graphed it for you in the image below.

Step-by-step explanation:

Graph the logarithmic function f(x) = log2(x - 1) + 2 is attached below.

The function is referred to as a particular kind of relationship, every value in the domain is associated with exactly one value in the range. They have a set perimeter and territory.

It is given that the logarithmic function is, f(x) = log2(x - 1) + 2.

The first step in graphing a logarithmic function is to locate some points on the exponential f. (x). The graph will look better as we plot more points, and we can flip the x and y values to get points on the opposite axis. locate the asymptote. The following logarithmic functions can be graphed. Specify the domain and the range.

Thus, the graph is attached below.

Answer:

10 x 15 = 150

Area of trapezoid:

10 + 20 = 30

30 x 5 = 150

20 - 15 = 5

150 divided by 2 ( x 1/2) = 75

75 + 150 = 225 square cm

Formula of a trapezoid:

B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)

Answer:

2: 45     3: 45   4: 135    5: 135   6: 45   7: 45

Step-by-step explanation:

they are vertical angles meaning they will mirror each other, subract 135 from 180 and you will get the other angle

x, x+10

5(x+10)=40+6x

5x+50=40+6x

x=10

and the other number is x+10

Hence teh numbers are 10,20

Answer:

x = 2 and -4

Step-by-step explanation:

(x + 1)² = 9

First, take the square root of both sides. This will eliminate the square on the left side.

(x + 1) = √9

Note that √9 can be 3 or -3.

Let's write out both possibilities.

(x + 1) = 3

(x + 1) = -3

Solve.

(x + 1) = 3

[subtract 1 from both sides]

x = 2

--

(x + 1) = -3

[subtract 1 from both sides]

x = -4

Your answers are 2 and -4.

Let's check our answers by plugging in the values back into the original equation.

(x + 1)² = 9

(2 + 1)² = 9

(3)² = 9

9 = 9

That solution is correct.

(x + 1)² = 9

(-4 + 1)² = 9

(-3)² = 9

9 = 9

That solution is also correct.

Your answer is correct.

Hope this helps!

The radius is 6

=791.28/3.14×7.0

=

[tex] \sqrt{36} [/tex]

=6

The radius of cylinder is 3.764 cm.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Finding an object's volume can help us determine how much material is needed to fill it, such as how much water is needed to fill a bottle, aquarium, or water tank.

Given volume of cylinder = 791.28 cm³

height  = 7.0 inches

so, 1 inch  = 2.54 cm

7 inch  = 2.54 x 7 = 17.78 cm

height  = h = 17.78 cm

volume of cylinder = πr²h

where r = radius

V = πr²h

791.28 = 3.14(17.78)r²

r² = 791.28/55.8292

r² = 14.1732

r = √14.17732

r  = 3.764 cm

Hence the radius  is 3.764 cm.

Explanation: A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

Explanation:

(a) Keep in mind the meaning of the variables:

With these definitions in mind, we can examine the constraints.

  x ≥ 0 . . . . . we cannot sell a negative number of PS4 units

  y ≥ 0 . . . . . we cannot sell a negative number of X.box 1 units

  y ≥ 5 . . . . . we intend to sell at least 5 X.box 1 units

  y ≤ 10 . . . . we cannot sell more than 10 X.box 1 units

  x + y ≤ 10 . . . . . we can sell at most 10 units total

(Please note that the constraints y ≥ 0 and y ≤ 10 are redundant to other more restrictive conditions.)

__

(b) The objective function tells us the total profit:

  P(x, y) = 100x + 80y

__

(c) Juan's goal: P(2, 7) = 100(2) +80(7) = 200 +560 = 760

  Justin's goal: P(4, 5) = 100(4) +80(5) = 400 +400 = 800

Meeting Justin's goal would result in more profit.

__

(d) It is not possible to sell a negative number of units*, so negative values for the variables do not make any sense. (This is consistent with the x≥0, y≥0 constraints above.)

_____

* Some linear programming problems plan for a certain number of returned items. Those could be considered to be negative sales.
