What is the area of a triangle if the vertices are at
A(-11, 4)
B(-7, 8)
C(-4, 4)

Answer:

x = 53°

Step-by-step explanation:

Forming the equation,

→ x + (2x + 21°) = 180°

Now the value of x will be,

→ x + (2x + 21°) = 180°

→ 3x = 180° - 21°

→ x = 159°/3

→ [ x = 53° ]

Hence, the value of x is 53°.

The inequality represented by the graph is y ≥ -x + 2

A graph is a pictorial representation of data and the graph presented represents inequality data

The graph shows a linear function written in the form

y = mx +c

where slope, m calculated as

c = intercept

x = input variables

y = output variables

calculation of slope

The points used for the slope is gotten from the graph as (0. 2)  (1, 1)

m = (y₂ -y₁) / (x₂ - x₁)

substituting the values

= ( 2 - 1 ) / ( 0 - 1 )

= 1 / -1

= -1

y intercept, c this is a point where the graph cuts the y axis

c = 2

The two points result greater than or equal to written with the symbol ≥

hence the equation is

y ≥ -x + 2

We deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit up in the graph of g(x). The best choice is C.

A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.

Right-shift a function

Inside the function's argument, subtract. For instance, is essentially moved b units to the right.

You go to the right while subtracting from the parameter of the function.

Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).

also to advance a function

Outside of the function, add. For instance, is essentially shifted up units.

G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.

Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).

Therefore, choice C is right.

The equation the function after the transformation is (c) g(x) = -√x  - 3

The equation of the function is given as

f(x) = √x ---- i.e the square root parent function

The sequence of transformations is given as follows:-

When the above transformations are combined, we have:

Translate up by 3 units: g(x) = f(x) + 3

Reflection across the x-axis: g(x) = -(f(x) + 3)

So, we have

g(x) = -(√x + 3)

Expand

g(x) = -√x  - 3

Hence, the function g(x) is (c) g(x) = -√x  - 3

The length of side GF from the similar triangles shown is GF = √10 units

A mathematical phrase known as an equation demonstrates the connection between two or more variables and numbers.

If a pair of triangles share the same shape, all of their angles are equal, and their ratio of comparable sides is proportionate, then they are said to be similar.

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." Standard form, slope-intercept form, and point-slope form are the three primary types of linear equations.

In a similar triangle, DE = GF, Hence:

GF/DF = GH/DE

GF / 5 = 2 / GF

GF² = 10

GF = √10

The table showing the possible value of S and their possibilities is attached below,

The probability that a player moves their counter forward more than 2 spaces is 0.5.

The Probability is the ratio of favorable outcomes to total number of outcomes. The probability of an event must be less than 1 as the sum of all probabilities of events is equal to 1.

Here, If the number on the dice is even, S is half that number; if it is not even, S is double that amount. The table showing the possible value of S and their possibilities is attached below,

Now, finding the probability that a player moves their counter forward more than 2 spaces,

As seen from the table, the number of favorable outcomes where the player moves the counter more than 2 spaces is 3.

The total number of outcomes is 6. so, the probability will be,

Probability [tex]=\frac{3}{6}[/tex]

Answer:

Each pineapple costs £0.70.

Step-by-step explanation:

Let P be the number of pineapples Helen purchased and C the cost per pineapple, in £.
