are -8h - 3.5 and -0.5(16h - 7) equalivalent expressions? ​

=========================================================

Explanation:

Draw a vertical line through the middle to split the figure into two rectangles.

The rectangle on the left is 21 ft by 7 ft. Its area is 21*7 = 147 sq ft.

The rectangle on the right is 24-7 = 17 ft by 21-10 = 11 ft. The area is 17*11 = 187 sq ft.

The combined area is therefore: 147+187 = 334 square feet

-------------

A different approach:

Draw a horizontal line through the middle to form two rectangles.

The rectangle on top is 10 ft by 7 ft with area of 10*7 = 70 sq ft.

The rectangle on the bottom is 24 ft by 12-10 = 11 ft, so its area is 24*11 = 264 sq ft.

Total area = 70+264 = 334 square feet

--------------

Yet another method:

Draw a horizontal line through the top most edge of the figure. Do the same for the right-most side of the figure. The two lines meet in the top right corner. This will form a rectangle that is 21 ft tall and 24 ft wide.

The area of this big new rectangle is 21*24 = 504 sq ft.

However, we don't want all of this area. We'll kick out the rectangular piece that is 10 ft tall by 24-7 = 17 ft across (in the upper right corner). The area we want to kick out is 10*17 = 170 sq ft.

The actual area we want is 504 - 170 = 334 square feet

There are probably other methods you could use to find the area of this figure.

$17.00

Step-by-step explanation:

The profit=67-50

Answer:

A parabola is a curve with a focus and a directrix. The focus is any point is at an equal distance while the directrix is a fixed line. The vertex of the parabola is (2,1), the two points to the right are (3,4) & (4,13) while the two points to the left are (1,4) & (0,13).

Given that:

y = 3(x - 2)² +1

A parabola is represented as:

y = a (x − h)² + k

Where:

Vertex = (h, k)

So, by comparison; the vertex of the function is:

Vertex = (2, 1)

To plot two points to the right, we select x values greater than 2.

Let: x = 3

So, we have:

y = 3(x - 2)² + 1

y = 3(3 − 2)² + 1

y = 4

Let x = 4

y = 3(x - 2)² + 1

Let x = 4

y = 3(x - 2)² +1

y = 3(4-2)² + 1

y = 13

To plot two points to the left, we select x values less than 2.

Let: x = 1

So, we have:

y = 3(x - 2)² +1

y = 3(1 − 2)² + 1

y = 4

Let x = 0

= 3(x - 2)² + 1 y =

y = 3(02)² +1

= 13

In conclusion:

• The vertex of the parabola is (2,1)

• The two points on the right are (3,4) and (4,13)

• The two points on the left are (1,4) and (0,13)

Step-by-step explanation:

to get around the red arc you would go alphabetically to the points M, N. since u already have 170° and a circles full rotation is 360° that means 360-170=190 and so the blue arc of the circle would either have to be 190° or 170°, and since the angle of the blue arc is farther than the red arc, that would mean the blue arc is 190°.

Answer:

x = 50°

Step-by-step explanation:

          A triangle has total interior of 180 degree .

x + 84° + 46° = 180°

x = 180° -46° -84°

x = 50°

In the given triangle, the value of x is determined to be 50°. In other words, The value of x in the triangle is 50°.

To find the value of x in a triangle with angles measuring 84°, 46°, and x°, follow these steps:

Step 1: Recall that the sum of the angles in a triangle is always 180 degrees.

Therefore, the sum of the three angles in the given triangle is:

[tex]84 + 46 + x = 180[/tex]

Step 2: Combine like terms and isolate x.

Start by subtracting 84 and 46 from both sides of the equation:

[tex]84 + 46 + x - 84 - 46 = 180 - 84 - 46[/tex]

[tex]x = 50^{\circ}[/tex]

Step 3: The value of x is 50. This means that the third angle in the triangle measures 50°.

By applying the fact that the sum of angles in a triangle is 180°, set up an equation and solve for x.

Answer:

Part 1:

-5, a multiplicity of 2

-1, a multiplicity of 1

4, a multiplicity of 3

7, a multiplicity of 1

Part 2: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex]

Step-by-step explanation:

This question has to be done visually, and can is a little tricky, because depending on the way the graph intercepts the x-axis, there is going to be a different number of roots.

The roots are represented by the intersection of the function with the x-axis.

To start, take a look at the point [tex](-5,0)\\[/tex], which intercepts the x-axis like a parabola(quadratic function). This means that -5 is a "double root" of the function, or it represents two roots of the function.

Now look at the point [tex](-1,0)\\[/tex], which intercepts the x-axis in a linear way, meaning that -1 is simply a "single-root" of the function, or it only represents one root.

So for the next root, look at [tex](4,0)[/tex], which intercepts the x-axis like a cubic function. This means that 4 is is a "triple-root" of the function, and represents 3 roots of the function.

And finally, we have one final interception at [tex](7,0)\\[/tex], and the interception is in a linear form, meaning 7 is simply a "single-root" to the function, or it only represents one root.

So we can conclude that the following are roots with their respective multiplicities

-5, a multiplicity of 2

-1, a multiplicity of 1

4, a multiplicity of 3

7, a multiplicity of 1

And totally, 2+1+3+1 gives us 7, which supports our answer because we know this is a seventh-degree polynomial.(1)

Now for Part 2

We simply take each root, and subtract it from x in our function, then apply our multiplicity as the exponent

So the function would be: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex](2)
