Based on the graph of z (x), what is the value of z-¹ (-2)?
​

Based on the amount that Tim had at the beginning of the month, the mowing of the lawn and washing of the car, the equation that represents the situation is b. 50 + 12 + 12 + 9 + (-15) + (-15) + (-35).

The amount of money that Time has left is $18

Tim gets $12 for every lawn he mows and $9 for every car he washes.

The amount he gets is:
= Amount started with + payment for mowing lawn + payment for mowing another lawn + payment for car wash

= 50 + 12 + 12 + 9

When the expenses of the video games and sweatshirt are thrown in, the formula becomes:

=  50 + 12 + 12 + 9 + (-15) + (-15) + (-35)

The amount that Tim is left with is:

= 50 + 12 + 12 + 9 + (-15) + (-15) + (-35)

New data point is residual.

When a data point is added or removed from the whole dataset, it might cause a significant change in the regression equation by either changing the slope or the relationship coefficient existing between the variables.

An influential point is one that changes the relationship existing between the dependent and the independent variables significantly in either direction.

Since the new observed data point decreases the slope of the regression line but increases the correlation coefficient existing between the independent and the dependent variable, we can probably say that the new data point is an influential point.

Thus, Option B. is correct.

Answer:

The value of k = 18 ± 2i √42 that is 18 + 2i √42 and 18 - 2i √42.

Step-by-step explanation:

An equation is given to be solved for the value of k, that is 1/4 k = 3 (-41/k + 3).

Now, let us rearrange the given equation;

=> 1/4 k = 3 (-41/k + 3)

=> 1/4 k - 3 (-41/k + 3) = 0

Let us simplify the equation;

=> 1/4 k - 3 (-41/k + 3) = 0

=> k/4 + (3 × 41)/k - 3 × 3 = 0

=> k/4 + 123/k - 9 = 0

=> k/4 + 123/k = 9

Now, multiply each side by 4k to eliminate the fractions;

=> (k/4 + 123/k) × 4k = 9 × 4k

=> 4k²/4 + 492k/k = 36k

=> k² + 492 = 36k

=> k² - 36k +492 = 0

So, this equation is a quadratic equation;

=> k = -b ± √(b² - 4ac) / 2a

=> k = -(-36) ± √((-36)² - 4 × 1 × 492) / 2 × 1

=> k = 36 ± √((-36)² - 4 × 492) / 2

=> k = 2 [36 ± √((-36)² - 4 × 492)] / 2

=> k = 18 ± √((18)² - 2 × 246)

After solving the above equation we get;

=> k = 18 ± 2i √42

Therefore, the value of k = 18 ± 2i √42 that is 18 + 2i √42 and 18 - 2i √42.

Answer:

One angle is 70 and the other angle is 110

Step-by-step explanation:

x + 40 = y

x + y = 180  Supplemental angles add to 180

Substitutes x + 40 into the second equation by y

x + x + 40 = 180  Combine like terms

2x + 40 = 180  Subtract 40 from both sides

2x = 140  Divide both sides by 2

x = 70

Substitute in 70 for x in either of the original 2 equations

x + y = 180

70 + y = 180  Subtract 70 from both sides

y = 110

m1=70

m2=110

supplementary angles are two angles that add up to 180 so all you need to do is make an equation to find the answer.

we can make m1=x and m2 = y

x is less than y by 40 degrees so y-40=x

then we use the equation x+y=180 and replace x with what we found out and solve for y.

(y-40)+y=180 ---> 2y -40 = 180 ---> 2y = 220 ---> y=110

x+y=180 ---> x+110=180 ---> x=70

Answer:

Step-by-step explanation:

The missing length of the given triangle with measurements using triangle proportion are;

For first diagram; x = 48

Foe second diagram; x = 60

For third diagram; x = 100

For fourth diagram; x = 25

What is triangle proportion?

According to the Triangle proportion rule, When a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.

In first diagram;

The side with x is a reflexive side of both triangles and as such from triangle proportionality theorem we can say that;

⇒ x/64 = 36/x

After cross multiply we get;

x² = 64 * 36

x = √2304

x = 48

Thus, we conclude that the missing length indicated is x = 48.

In second diagram;

Let y is the smaller side of the base out of which 64 has been taken.

Thus; y = 100 - 64

        y = 36

Let the perpendicular height of triangle is 'z';

z/36 = 64/z

z² = 64 * 36

z = √2304

z = 48

Now, For finding the value of x we can apply the Pythagoras theorem;

x² = 48² + 36²

x² = 2304 + 1296

x² = 3600

x = √3600

x = 60

So, The missing length indicated is x = 60.

In third diagram;

Let the perpendicular height of triangle is 'y'.

Then apply Pythagoras theorem as;

60² = 36² + y²

y² = 3600 - 1296

y = √2304

y = 48

Now, Apply the triangle proportionality theorem we get;

48/36 = (x - 36)/ 48

48 * 48 = 36 (x - 36)

64 = x - 36

x = 64 + 36

x = 100

Hence, The missing length indicated is x = 100.

In fourth diagram;

Let the perpendicular height of triangle is 'y';

Apply Pythagoras theorem as;

15² = 9² + y²

y² = 225 - 81

y = √144

y = 12

Now, Apply the triangle proportionality theorem we get;

12/9 = (x-9) /12

144 = 9 (x-9)

16 = x - 9

x = 25

So, The missing length indicated is x = 25.

Therefore, The missing length of the given triangle with measurements using triangle proportion are;

For first diagram; x = 48

Foe second diagram; x = 60

For third diagram; x = 100

For fourth diagram; x = 25

gimmeeeeee 10000 pointttsss.

The mistake made by the student was using the composition f ° g(x) instead of g ° f(x). The correct form is g( f(0)) = - 9 / 2.

In this question we find two functions, with which we should perform an operation known as composition. Composition consists in substituting the input of a function by the other function. The operation is defined by the following expression:

f ° g (x) = f [g (x)]

Herein we must determine the mistake done by the student on the composition. If we know that f(x) = (3 · x - 7) / 4, g(x) = 2 · x - 1 and x = 0, then the value of g(f (0)) is:

g ° f (x) = g (f (x))

g ° f (x) = 2 · [(3 · x - 7) / 4]  - 1

g ° f (x) = (3 · x - 7) / 2 - 1

g ° f(x) = (3 / 2) · x - 7 / 2 - 1

g ° f(x) = (3 / 2) · x - 9 / 2

g ° f(0) = (3 / 2) · 0 - 9 / 2

g ° f(0) = - 9 / 2

Answer: A side of a square for the area given 100/9 square meters, then length = 3.33 meters .

Step-by-step explanation:

The area of a square is (100/9) cm.

So, find out the length of the square?

Then,

Define Square:

A square is closed, two-dimensional shape with 4 equal sides. A square is a quadrilateral. We can find the shape of a square in a game board or chess board, a wall clock and in a slice of bread, around us.

The area of any rectangle is length times width. The area of a square is a special case where length equals width, so side times side or side squared is used for area.

Define Area of Square:

Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure. The measurement is done in square units with the standard unit being square meters (m²).                    

The area of any rectangle is length times width. The area of a square is a special case where length equals width, so side times side or side squared is used for area.    

Area of a Square = Side ×  Side

Therefore, the area of square = side²  square units                          

                                              A = s²

Means,       A= area of square

You have the area so you need to find the side length that when multiplied by itself equals that area. If you don’t know what number squared is (100/9) you can plug and chug or use a calculator with square roots.

Replace with A=(100/9) values,

We can write,

                        A = s²

               (100/9) = s²

Then we can solve it,

               [tex]\sqrt{100/9}[/tex] = s

                 [tex]\sqrt{\frac{(10^{2}) }{3^{2} } }[/tex] = s

We can write, [tex]\sqrt{10^{2} }[/tex] = 10 , and [tex]\sqrt{3^{2} }[/tex] = 3

Then,  

                    (10/3) = s

Therefore,   s = (10/3)

                    s = 3.33 meters

So, length = 3.33 meters

The transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units

The equation of the functions are given as

f(x)= (4x - 8)^2

g(x) = x^2

Start by stretching the function g(x) horizontally by a scale factor of 4

This is represented as

g'(x) = g(4x)

So, we have

g(4x) = (4x)^2

This gives

g'(x) = (4x)^2

Next, we translate the function down by 8 units

This is represented as

f(x) = g'(x - 8)

So, we have

f(x) = (4x - 8)^2

Hence, the transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units
