Find the derivative of √2-3x using first principle method​

Answer: 12

Step-by-step explanation:

x/6 = 2

you have to divide x equally into 6 two times to find x you have to

Times the Denominator and the answer (6·2)

which results in being 12

and to check you plug 12 into x and get this 12/6 = 2

6*2 = 12

so 12 was divided 2 times into 6 and you get 2 = 2

The number of cubes made from the given cuboid is 9.

From the given figure, height =6 units, width =4 units and length =3 units.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

a) Now, volume of cuboid = Length × Width × Height

= 3×4×6

= 72 cubic units

From the figure, edge of cube is 2 units

b) Volume of cube =a³, where a is edge

= 2³

= 8 cubic units

Number of cubes = Volume of cuboid/Volume of cube

= 72/8

= 9

Therefore, the number of cubes made from the given cuboid is 9.

A horse trainer records the distance a horse travels during three different trials.

The horse's average speed = 0.3 kilometers per minute.

Given the following data:

Time 1 = 15 minutes

Time 2 = 30 minutes

Time 3 = 45 minutes

Distance 1 = 4.5 kilometers

Distance 2 = 9.0 kilometers

Distance 3 = 13.5 kilometers

To determine the horse's average speed in kilometers per minute:

First of all, we would find the total time and total distance covered:

For total time:

Total Time = 15+30+45

Total time = 90 minutes

For total distance:

Total Time = 4.5+9.0+13.5

Total time = 27 kilometers.

Mathematically, average speed is given by the formula:

[tex]Average speed = \frac{Total Distance}{Total Time}[/tex]

[tex]Average Speed = \frac{27}{90}[/tex]

Hence, the answer is the horse's average speed = 0.3 kilometers per minute.

The height of the box is 2.15 inches.

Let the height be 'h'

Given, length is 5 inches more than height, l = h + 5

Width is 2 times the height, b = 2h

Total Volume of rectangular box = 66 in³

⇒ l×b×h = 66

⇒ (h+5)(2h)h = 66

⇒ 2h³ + 10h² = 66

⇒ 2(h³ + 5h²) = 2×33

⇒ h³ + 5h² - 33 = 0

We need two factors of 4 and two factors of -1.

4 factors into 4 and 1, 2 and 2.

-1 factors into -1 and 1.

The degree measure of each angle in the triangle are:

F = 31°

G = 90°

H = 59°

It is important to note the following in the triangle:

Sum of all angle in a triangle = 180°

A right angle = 90°

Therefore, since G is a right angle, it's 90°.

H = 5x - 16

F = 3x - 14

The value of x will be found thus:

F + G + H = 180°

3x - 14 + 90° + 5x - 16 = 180

Collect like terms

3x + 5x = 180 + 14 - 90 + 16

8x = 120

Divide

x = 120 / 8

x = 15°

Therefore,

H = 5x - 16

H = 5(15) - 16

H = 75 - 16

H = 59°

F = 3x - 14

F = 3(15) - 14

F = 45 - 14

F = 31°

By translating the pre-image triangle CRT with this translation rule (x, y) →  (x + 2, y - 4), the coordinates of the image triangle C'R'T' are: C' (-2, -2), R' (-3, -5), and T' (3, -3).

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or parent function.

Note: Each interval on this graph represents 1 unit.

Next, we would transform triangle CRT by using this translation rule (x, y) →  (x + 2, y - 4) to create the vertices of triangle C'R'T' as follows:

(x, y)                    →        (x + 2, y - 4)

Point C (-4, 2)     →       Point C' = (-4 + 2, 2 - 4) = (-2, -2)

Point R (-5, -1)     →       Point R' = (-5 + 2, -1 - 4) = (-3, -5)

If a straight line has a gradient of 3 and passes through a point (2, 10), then the equation of the line is [y = (3x + 4)].

As per the question statement, a straight line has a gradient of 3 and passes through a point (2, 10),

And we are required to determine the equation of the above mentioned line.

To answer this question, we need to know the formula to determine the equation of a straight line having a known slope, say "m", and passing through a known point, say (x₁, y₁), which goes as,

[(y - y₁) = {m(x - x₁)]

Here, since our concerned line has a gradient of 3, i.e., (m = 3), and passes through a point (2, 10), i.e., [(x₁, y₁) = (2, 10)], using these values in the above mentioned formula to determine the equation of a straight line having a known slope and passing through a known point, we get,

[(y - 10) = {3(x - 2)}]

Or, [(y - 10) = (3x - 6)]

Or, [y = 3x + (10 - 6)]

Or, [y = (3x + 4)]

That is, the equation of a straight line having a gradient of 3 and passing through a point (2, 10) is [y = (3x + 4)].

To calculate the horizontal displacement of a horizontally launched projectile.

The formula for calculating the horizontal displacement of a horizontally launched projectile is [tex]x = v*t[/tex]

A projectile launched horizontally with a velocity v, at a height y ,travels a horizontal distance x, while falling through a distance y.

The horizontal velocity of a projectile remains constant throughout its motion, in the absence of air resistance. The vertical component of the velocity is under the action of the gravitational force and hence it increases in magnitude as it falls through the height.

The horizontal displacement of the projectile is a uniform motion and it occurs at a constant speed v.

Hence, the horizontal displacement of the projectile is given by the expression.[tex]x = v*t[/tex]

It would help to recreate the problem variables in the math equation editor, or define what you mean by "vi(cos )t"  and "[tex]v*t[/tex]".  These are somewhat vague descriptions.

The error Noa made is:

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 =  45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.
