To obtain an amount of 3 / 2 cups of flour, then we need three halves of cup by means of a 1 / 2 cup measuring cup.

In this problem we have the case of recipe that requires 3 / 2 cups of flour in terms of certain number of measuring cups with an amount of 1 / 2 cups. The number of measuring cups (n) is equal to the total required by the recipe (M) divided by the amount of the measuring cup (m), both in cups. That is:

n = M / m

If we know that m = 1 / 2 cup and M = 3 / 2 cup, then the number of measuring cups is:

n = (3 / 2 cup) / (1 / 2 cup)

n = 3

In other words, we need 3 halves of a cup of flour to obtain the required amount of 3 / 2 cups.

The image after the transformations of rotation, translation or reflection can be found by certain operation or rotation.

We can find how to know the image of certain figures after the given transformations are done.

91) Here it is translation.

x coordinates are shifted to right by 3 units and y coordinates are shifted to  down by 5 units.

So the entire graph will be shifted to right by 3 units and down by 5 units.

92) Here, the translation is by not shifting the x coordinates and shifting the y coordinates 2 units to the down.

So the entire graph will be shifted to down by 2 units.

93) When a graph is reflected across x = -2, then the graph is moved horizontally such that the original figure and the image will be at the same distance from x = -2.

94) When a graph is reflected across y = 1, then the graph is moved vertically such that the original figure and the image will be at the same distance from y = 1.

95) When a graph is rotated about the origin 180°, if it is clockwise or anticlockwise, each of the coordinates (x, y) in the graph will become (-x, -y).

96) If the rotation is 90° counterclockwise about the origin, the coordinates (x, y) in the original graph becomes (-y, x).

The slope is m = RISE / RUN, and the change in y is frequently referred to as "RISE."

[tex]5*x-6*y-(42)=0[/tex]

Tiger understands that this is a straight line equation. Typically, this equation is expressed as y=mx+b (or "y=mx+c" in the UK).

A straight line drawn using the Cartesian coordinate system has the formula "y=mx+b," where "y" denotes the vertical axis and "x" denotes the horizontal axis.

In this equation, y represents how high the line rises, x represents how far it travels along, m represents the slope or gradient, or how steep the line is, and b represents the Y-intercept, or the point at which the line crosses the Y axis.

The X, Y, and slope are collectively referred to as the line properties. We will now plot the line 5x-6y-42 = 0 and determine its characteristics.

x = 0 the value of y is 7/-1 so this line "cuts" the y axis at y=-7.00000

y-intercept = 42/-6 = 7/-1  = -7.00000

y = 0 the value of x is 42/5 Our line therefore "cuts" the x axis at x= 8.40000

x-intercept = 42/5  =  8.40000

Answer:

The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. If the coordinates of one endpoint are (x1, y1) and the coordinates of the other endpoint are (x2, y2), then the coordinates of the midpoint are given by:

M = ((x1 + x2)/2, (y1 + y2)/2)

In this case, the coordinates of the midpoint are (4, 0), and the coordinates of AA are (3, -1). Therefore, the coordinates of BB must be (5, 1).

You can confirm this by calculating the midpoint using the coordinates of AA and BB:

M = ((3 + 5)/2, (-1 + 1)/2)

= (4, 0)

This shows that the point (5, 1) is indeed the other endpoint of the line segment, and the coordinates of BB are (5, 1).

From the given triangle diagram figure, angles are -

m∠1 = 72°

m∠2 = 114°

m∠3 = 66°

m∠4 = 66°

m∠5 = 56°

m∠6 = 32°

Depending on how many sides a polygon has, it is given a unique name. Because "tri" is a word that indicates "three," the polygon with three sides is known as a triangle. This polygon has three angles, as indicated by its name. Poly means numerous in the prefix.

Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The triangle's three angles add up to a total of 180 degrees.

In the given problem,

m∠6 = 180° - (90° + 58°)

so, m∠6 = 32°

Next, m∠1 +m∠6  = 180° - (42° +34°)

                             = 104°

so, m∠1 = 104° - 32°

             = 72°

Next, m∠5 = 90° - 34°

m∠5 = 56°

Again, m∠4 = 180° - (56° + 58°)

m∠4 = 66°

Now from the figure, m∠3 and m∠4 are vertically opposite angle.

So, m∠3 = 66°

Again, m∠2 = 180° - 66° = 114°

Top line:

100% - 80% = 20%

20% of 60 = 0.2 × 60 = 12

Small piece on top is 12.

Second line:

Small piece is 12.

100% - 60% = 40%

Small piece is also 40%.

40% of x = 12

0.4x = 12

x = 12/0.4

x = 30

The entire second line is 30.

60% of 30 = 0.6 × 30 = 18

60% of second line is 18.

Third line:

30% of third line = 18

100% - 30% = 70%

30/18 = 70/x

30x = 18 × 70

x = 42

Larger part of third line is 42.

The required function f(x) is represented by -1 + F(x + sin(x)).

To find the function f(x), you can use the formula for integration by substitution:

f(x) = F(g(x)) + C

where F is an antiderivative of f, g is a function such that g'(x) = f(x), and C is a constant.

In this case, we can take g(x) = x + sin(x). Then g'(x) = cos(x), so f(x) = F(g(x)) + C = F(x + sin(x)) + C.

We are given that f'(π) = 2 and f(π) = -1, so we can use these values to find the constants C and F.

First, we can find F by taking the derivative of F(x + sin(x)). This gives us:

F'(x + sin(x)) = f(x) = cos(x)

Substituting x = π and using the fact that F'(x + sin(x)) = f'(π) = 2, we get:

F'(π + sin(π)) = 2

Since sin(π) = 0, this simplifies to:

F'(π) = 2

Then, using the fact that F(x + sin(x)) = f(π) = -1 when x = π, we can find the value of F(π):

F(π) = -1

Now that we have found the values of F and F', we can use these to find the value of C.

Since F(x + sin(x)) = F(x) + F'(x) sin(x), we can substitute x = π to get:

F(π + sin(π)) = F(π) + F'(π) * sin(π)

Substituting the values we found above, this becomes:

F(π + 0) = -1 + 2 x 0

Which simplifies to:

F(π) = -1

Since F(π) = -1, we can conclude that C = -1.

Therefore, the function f(x) is given by:

f(x) = F(x + sin(x)) + C = F(x + sin(x)) - 1

= -1 + F(x + sin(x))

Answer:

8m = 800cm

8m = 0.008km

Step-by-step explanation:

1 kilometer is 1000 meters

1 meter is 100 centimeters

You'd only have to multiply in the first one:

[tex]8 \times 100 = 800[/tex]

8m = 800cm

Remember that when multiplying by 100 you only have to add zeros.

For km, as it is bigger than m you have to divide by 1000, when dividing this time you only have to carry an imaginary point starting from right to left, the amount of zeros there are:

[tex]8. \\ .8 \\ .08 \\ .008 \\ 8 \div 1000 = .008[/tex]

8m = 0.008km

If you run out of numbers when carrying the point, just add zeros.

Answer:

(- 4, 2 )

Step-by-step explanation:

x + 5y = 6 → (1)

x + 3y = 2 → (2)

subtract (2) from (1) term by term to eliminate x

(x - x) + (5y - 3y) = 6 - 2

0 + 2y = 4

2y = 4 ( divide both sides by 2 )

y = 2

substitute y = 2 into either of the 2 equations and solve for x

substituting into (1)

x + 5(2) = 6

x + 10 = 6 ( subtract 10 from both sides )

x = - 4

solution is (- 4, 2 )

Answer:  the solution to the system of equations is x = 12 and y = 16.

Step-by-step explanation: To solve this system of equations, you can use the method of substitution.

First, solve one of the equations for one of the variables. For example, you can solve the first equation for x:

2x + y = 40

2x = 40 - y

x = (40 - y)/2

Then, substitute this expression for x in the second equation:

x - 2y = -20

(40 - y)/2 - 2y = -20

Multiplying both sides by 2, we get:

40 - y - 4y = -40

-5y = -80

y = 16

Substituting this value for y in the first equation, we can solve for x:

2x + 16 = 40

2x = 24

x = 12

Therefore, the solution to the system of equations is x = 12 and y = 16.
