Can someone please help me with this

Answer:

m∠A = 106°

Step-by-step explanation:

All three sides of the triangle are given in the question.

To find the measure of included angle A between two sides we will apply cosine formula,

BC²= AB² + AC² - 2(AB)(AC)cosA

(13)² = (10)² + (6)² - 2(10)(6)cosA

169 = 100 + 36 - 120cosA

cosA = [tex]\frac{-169+136}{120}[/tex]

cosA = -0.275

A = [tex]\text{cos}^{-1}(-0.275)[/tex]

A = 105.96°

A ≈ 106°

Therefore, m∠A = 106° will be the answer.

Answer:

[tex]Area = 210m^2[/tex]

Step-by-step explanation:

The attached shape is a trapezium and the given dimensions are:

[tex]B_1 = 10m[/tex] -- Base 1

[tex]B_2 = 20m[/tex] --- Base 2

[tex]H = 14m[/tex] --- Height

Required

Calculate the area

The area is calculated as thus:

[tex]Area = \frac{1}{2}(B_1 + B_2) * H[/tex]

[tex]Area = \frac{1}{2}(10m + 20m) * 14m[/tex]

[tex]Area = \frac{1}{2}(30m) * 14m[/tex]

[tex]Area = 15m * 14m[/tex]

[tex]Area = 210m^2[/tex]

Answer:

If the vertical line intersects the graph in at most one point, then the given graph represents a function. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function.

I HOPE IT HELPS

TAKE CARE

Step-by-step explanation:

Answer:

Step-by-step explanation:

For a graph to be a function, there must not be more than one element in the range for each element of the domain.

If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value  paired with it.

Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.

This is called the vertical line test.

Answer:

-a > -b

Step-by-step explanation:

On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).

The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.

If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.

So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.

Example: let a = 3 and b =5.  

It is true that 3 < 5.

But it is NOT true that -3 < -5. It's the other way around!

-5 < -3

So, if a < b, then -a > -b.

Answer:

x:0 y: 3

x: 1 y: -1

x: 2 y: 1

Step-by-step explanation:

The coordinates of line is (0, -3), (1, -1) and (2, 1)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 2x - 3

Now, putting x=0

y= -3

and, x= 1

y= 2(1)-3

y = -1

and, x= 2

y=2 (2)- 3

y = 1

Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

Answer:

x = 14

Step-by-step explanation:

3 (x - 3) + 8x = 5 (2x + 1)​

FOIL: 3x - 9 + 8x = 10x +5

Move all the x terms to one side and all the constants to the other:

3x + 8x - 10x = 5 + 9

Combine like terms: x = 14

Answer:

16m

Step-by-step explanation:

Separate the rectangle from the triangle. The area of the rectange is 10m. We know this because l x w (2m x 5m).

Now for the triangle;

The area of a triangle is b x h / 2. We take the full height of the figure and subtract 5 from it giving us 3 which is our height for the triangle. We then see that 2m is on the bottom and we add that 2m to the two separate 1m giving us 4m in total.

Now that we have the base and height of the triangle we plug in giving us 6m. Finally we add both the areas; 10m + 6m = 16m.

Answer:

40 sq feet

Step-by-step explanation:

(im bad at explaining)

1 x 2 = 2 sq ft

3 x 2 = 6 sq ft

4 x 12 = 48 sq ft

2 sq ft + 6 + sq ft = 8 sq ft

48 - 8 = 40

The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².

Area of a rectangle = lenght × width.

The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)

The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)

The amount of square feet of outdoor carpet needed = 48 - (6 + 2)

The amount of square feet of outdoor carpet needed = 40 ft²

Given:

The table represents a proportional relationship.

To find:

The equation of the function.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]     ...(i)

where, k is the constant of proportionality.

From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).

Putting x=2 and y=1 in (i), we get

[tex]1=k(2)[/tex]

[tex]\dfrac{1}{2}=k[/tex]

Putting [tex]k=\dfrac{1}{2}[/tex], we get

[tex]y=\dfrac{1}{2}x[/tex]

Therefore, the correct option is A.

The scatter plot represents the monthly sales and the trend line that best fits the data is that of the line in graph four. Hence option D is correct.

A scatter plot is also called a scattergraph and is similar to one graph. The scatter plot uses the X and Y-axis. The makes use of the point to present the individuals and these are useful to see if the individual pieces of data fit into the graph being depicted these are useful for two variables and help to state the relation.
