What’s the difference in these two questions and why did we divide in one and multiple in one ( also why did we divide by8 in question 2)

Answer:

First is b; because [B1] is [A1] multiplied by -4

Second is c; because [C2] = 7[B1] + [B2]

[tex]~~~~~~x^2 -10x +10 =0\\\\\implies x^2 -2 \cdot 5 \cdot x +5^2 -5^2 +10 = 0\\\\\implies (x-5)^2 -25+10 = 0\\\\\implies (x-5)^2 -15=0\\\\\implies (x-5)^2 = 15[/tex]

Answer:

See below ~

Step-by-step explanation:

Applying section formula :

⇒ x = 1(14) + 2(2) / 1 + 2 = 18/3 = 6

⇒ y = 1(14) + 2(2) / 1 + 2 = 18/3 = 6

We understand after substituting the values of the endpoints in the section formula that the Point X divides the line in the ratio 1 : 2.

The angle of depression from the aeroplane to the ground​ will be 30 degrees.

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

Given that:-

The angle of depression will be calculated as the angle between the horizontal and the height of the plane as shown in the figure below.

As we know that the perpendicular theta is height and the base ratio is angle tan theta.

tanФ = Height / Base

tanФ  = 10 / 10 √3

tanФ = 1 / √3

Ф = tan⁻¹( 1 / √3 ) = 30°

Therefore the angle of depression from the aeroplane to the ground​ will be 30 degrees.

y=3x-13

Step-by-step explanation:

Answer:

Correct option is A)

A={1,2,3,4,5,6}

f:A→A

∴ Number of onto function=n!

       =6!

                                           =6×5×4×3×2×1

∴ Number of onto function=720

Step-by-step explanation:

Answer:

So first we substitute -2 for x

f(-2) = 10(-2)^2 - 4(-2) - 5

f(-2) = 400 + 8 - 5

Step-by-step explanation:

[tex]~~~~x^2 = 16\\\\\implies x = \pm\sqrt{16}\\\\\implies x =\pm 4\\\\\implies x = 4 ,~ x = -4[/tex]

Answer:

x = 4

Step-by-step explanation:

x² = 16

We do the opposite of x² , so we [tex]\sqrt{x}[/tex] (square root) both sides

[tex]\sqrt{x}[/tex] = [tex]\sqrt{16}[/tex] = 4

to confirm this, we can square 4, which gets us 16.

The coordinates of the point that divides the segment into a 3:2 ratio is (-2.2, -1.2)

The points are given as:

G = (-4,3)

H = (-1,-4)

Ratio, m : n = 3 : 2

The coordinate of the point is calculated using:

[tex](x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)[/tex]

This gives

[tex](x,y) = \frac{1}{3 + 2} * (3 * -1 + 2 * -4, 3 * -4 + 2 * 3)[/tex]

Evaluate

[tex](x,y) = \frac{1}{5} * (-11, -6)[/tex]

Evaluate the product

This graph represents a function Because it passes the vertical line test.

Let us first understand the Vertical Line Test.

In this test, we draw a few random vertical lines on a graph and check whether any one or more than one lines intersect the graph, no matter once or more.

If there exists a line that intersects the graph, we say the graph passes the vertical line test.

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

Hence this graph passes the vertical line test because there are many vertical lines that intersect it.

It makes that every time we flip a fair the probability of flipping tails is 50%.

Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. If it is equally likely and unlikely that the event would happen, it would have a probability of 0.5

Probability of flipping tails = number of tails / number of sides

Function rule describes the translation OT_1-9(x, y)

A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation.

A square on a coordinate plane is translated 9 units down and 1 unit to the right.

Let's (x, y) be the coordinate.

where x be the horizontal move and y be the vertical move.

As, it is translated 9 units down and 1 unit right.
