Answer:

2 x 10^1

9.999 x 10^4

Step-by-step explanation:

when using scientific notation

M x 10^X

M has to be between 1(inclusive) and 10

and has to be multiplied by ten to the power of x

Answer:

2 x 10^1

9.999 x 10^4

Step-by-step explanation:

For a number to be written in Scientific Notation, it has to abide to 2 rules:

1) It has to be within 1 and 10.

2) It has to be multiplied by ten to the power of a number(x)

Ex:

1.473 x 10^7 is written in Scientific Notation

6.9 x 17^3 is not written in Scientific Notation

0.372 x 10^39 is not written in Scientific Notation

This all means that 4.38 x 5^10 and 0.641 x 10^3 are not written scientific notation, as they do not abide to all the rules of the equation to be written in Scientific Notation, meanwhile 2 x 10^1 and 9.999 x 10^4 are written in Scientific Notation, as they abide to all rules of an equation to be written in Scientific Notation.

Answer:

110°

Step-by-step explanation:

Let the third angle be x. All the angles in a triangle add up to 180°. From the previous statement, we can write the equation:

25° + 45° + x = 180°

70° + x = 180°

x = 110°

Answer:

3π

Step-by-step explanation:

The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.

The radius is given ad 6. So the circumference is:

2*π*6=12π

Now, since the angle of the arc is 90°, this is 1/4 of the circle.

This means that the arc length of this section will be 1/4th of the total circumference which is:

12π/4=3π

The ordered pair (1, 2) is a solution to the system of inequalities

x + y > 2 and

3x + 2y ≤ 6.

To find an ordered pair that is a solution to the system of inequalities:

Start with the first inequality:

x + y > 2.

Choose a value for x and y that satisfies this inequality. For example, let's choose

x = 1 and

y = 2.

Substituting these values into the inequality:

1 + 2 > 2, which is true.

Now, let's move to the second inequality:

3x + 2y ≤ 6.

Substitute the same values, x = 1 and

y = 2, into this inequality:

3(1) + 2(2) ≤ 6.

Simplifying, we have:

3 + 4 ≤ 6, which is true.

Therefore, the ordered pair (1, 2) is a solution to the given system of inequalities.

Hence the ordered pair (1, 2) is a solution to the system of inequalities

x + y > 2 and 3x + 2y ≤ 6.

The standard deviation for the random variable X, the number of wins, is approximately 0.10341.

Probability of winning a certain lottery \(= 1/51,949\)

560 times were played overall.

Let X represent the random variable that represents the number of victories out of 560 plays.

The probability of winning in one play is \(p = 1/51,949\). The probability of not winning in one play is \(q = 1 - p\)

\(q = (51,949 - 1) / 51,949\)

\(q = 51,948 / 51,949.\)

What X should actually be is:

\(E(X) = np\)

\(E(X) = 560 * (1/51,949)\)

\(E(X) = 0.010793\)

The variance of X is:

\(Var(X) = npq\)

\(Var(X) = 560 * (1/51,949) * (51,948/51,949)\)

\(Var(X) = 0.010699\)

The value of X's standard deviation is

\(SD(X) = \sqrt{Var(X)}\)

\(SD(X) = \sqrt{0.010699}\)

\(SD(X) = 0.10341\)(approx)

Therefore, the standard deviation for the random variable X, the number of wins, is approximately 0.10341.

The volume of the sphere, in this case, is approximately 5378.24 cubic inches.

To find the volume of a sphere, we can use the formula:

V = (4/3) * π * r^3

where V represents the volume and r represents the radius of the sphere.

In this case, you mentioned that the radius of the disco ball is 16 inches. To calculate the volume, we substitute this value into the formula:

V = (4/3) * π * (16)^3

First, let's calculate the value of (16)^3:

(16)^3 = 16 * 16 * 16 = 4096

Now, we can substitute the values into the formula:

V = (4/3) * 3.14 * 4096

Simplifying further:

V = (4/3) * 3.14 * 4096

V = 5378.24

Thus, the answer is approximately 5378.24 cubic inches.

The area of rhombus KLMN is 287.3 in²

A quadrilateral called a rhombus has four equal-length sides. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

Given:

Since, the diagonals of a rhombus bisects each other at a right angle,

Let they bisect at O,

so, KM = 2MO = 2KO = 2×11.4 = 22.8 in

Thus, Δ KON is a right triangle,

Using Pythagoras theorem,

KN² = KO² + ON²

ON = √17²-11.4²

ON = 12.611 in

LN = 2×12.611

LN = 25.22 in

Then, Area of a rhombus = 1/2 × diagonal 1 × diagonal 2

Area = 1/2 × 25.22 × 22.8

        = 287.3 in²

Hence, the area of rhombus KLMN is 287.3 in²

Answer:

Step-by-step explanation:

Sub both sides by 3 then describe 20 by 5.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

B po sure po ako

Step-by-step explanation:

keep. learning po

Step-by-step explanation:

we have two lines you have to draw.

one is all in the bottom left quadrant (for x<=0) and one in the upper right quadrant (for x>5).

the easiest is for x>5. the line function is only

f(x) = y = 3

so, this is a horizontal line on the grid line for y = 3. it starts above x=5 and then goes all the way to the right ("to infinity and beyond !"). just, if possible, mark the starting point at x=5 as a little empty "circle" instead of a full dot, as x=5 is explicitly excluded (due to x>5).

and for x<=0 the line

f(x) = y = 4x - 3

goes sharp down but goes a little bit to the left the further down it goes. it starts with x=0, which gives y=-3 per the function.

so, the starting point (with a full dot, as x=0 is included) is (0,-3).

from there it goes sharp down and a little bit to the left.

for example the next point is for x=-1, which gives y=-7, so it is the point (-1,-7). x=-2 gives y=-11 and the point (-2,-11).

the line has to go through so these points and further down (again, "to infinity and beyond !"), as to move further left on the negative x-axis.

The derivative dy/dx at the point (-1,3) of the given equation, -8x² + 24xy - 16y² - 50x + 44y + 42 = 0. The value of dy/dx at (-1,3) is 7/8.

To find dy/dx using partial derivatives, we need to compute the partial derivatives ∂f/∂x and ∂f/∂y of the equation, where f(x, y) = -8x² + 24xy - 16y² - 50x + 44y + 42.

Taking the partial derivative with respect to x, ∂f/∂x, we differentiate each term of f(x, y) with respect to x while treating y as a constant. This gives us -16x + 24y - 50.  

Similarly, taking the partial derivative with respect to y, ∂f/∂y, we differentiate each term of f(x, y) with respect to y while treating x as a constant. This gives us 24x - 32y + 44.  

To find the values of x and y at the point (-1,3), we substitute these values into the partial derivatives: ∂f/∂x(-1,3) = -16(-1) + 24(3) - 50 = 58, and ∂f/∂y(-1,3) = 24(-1) - 32(3) + 44 = -92.  

Finally, we calculate dy/dx by evaluating (∂f/∂y) / (∂f/∂x) at the point (-1,3): dy/dx(-1,3) = (-92) / 58 = 7/8.  

Therefore, the value of dy/dx at the point (-1,3) is 7/8.
