Step-by-step explanation:

The product of 4.01 × 10⁻⁵ and 2.56 ×10⁸ is 1.0266×10⁴

A number system is defined as a system of writing to express numbers.

We have to find the product of 4.01 × 10⁻⁵ and 2.56 ×10⁸

Four point zero one times of ten to the power of minus five and two point five six times of ten to the power of eight.

These numbers are in the form of scientific notation.

Scientific notation is a way of writing very large or very small numbers.

So we have to take the product of decimal numbers and we have to add the powers of base 10.

(4.01×2.56)10⁻⁵⁺⁸

In the power -5 and 8 are added to get 3.

10.266×10³

1.0266×10⁴

Hence, the product of 4.01 × 10⁻⁵ and 2.56 ×10⁸ is 1.0266×10⁴

Answer:

The answer is the range of the function y = x + 3 when the domain is {-2, 0, 4}, which is the set {1, 3, 7}.

Step-by-step explanation:

The range of the function y = x + 3 is the set of all possible values of y for a given value of x in the domain of the function. In this case, the domain of the function is the set {-2, 0, 4}, so the range of the function is the set of all possible values of y for x equal to -2, 0, and 4.

To find the range, we need to substitute each of these values of x into the equation y = x + 3 and solve for y. When x = -2, we have y = -2 + 3 = 1. When x = 0, we have y = 0 + 3 = 3. And when x = 4, we have y = 4 + 3 = 7. Therefore, the range of the function y = x + 3 when the domain is {-2, 0, 4} is the set {1, 3, 7}.

The probability that a red card is drawn at least once by the third draw is 0.88.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Let, a card is drawn from a standard deck of 52 cards and then placed back into the deck.

In a standard 52 card deck the red cards are 26.

So,

P(red) =  n(red cards) / n(total cards)

          = 26 / 52

P(red) = 0.50

Now, X ≈ Bin (n = 3, P = 0.50)

P(X = x) = (n  x) p^x (1 - p)^n-x

(n  x) = \(\frac{n!}{x!(n-x)!}\)

P(X ≥ 1) = 1 - P(X < 1)

            = 1 - P(X = 0)

            = 1- (3  0)(0.5)^0(0.5)^3

            = 1 - 0.125

             = 0.875

P(X ≥ 1)  = 0.88

Hence, the probability that a red card is drawn at least once by the third draw is 0.88.

The correct answer is: O Yes, distance and angle measure are preserved.

When a triangle ABC is reflected across the line y = x, the pre-image and image are congruent.

This is because the line y = x is the perpendicular bisector of the segment joining each corresponding point of the pre-image and image.

Reflection across the line y = x is a type of transformation known as an isometry, which preserves both distance and angle measure.

Here's why:

Distance preservation:

When a point is reflected across the line y = x, the distance between the original point and its reflection remains the same.

This holds true for all corresponding points of the triangle.

Therefore, the distance between any two corresponding points in the pre-image and image triangle will be equal, resulting in distance preservation.

Angle preservation: When a line segment is reflected across the line y = x, the angle between the line segment and the line y = x is preserved. This means that the corresponding angles in the pre-image and image triangle will be congruent.

Since both distance and angle measure are preserved during reflection across the line y = x, the pre-image and image triangles are congruent.

It's important to note that congruence under reflection across a line holds only when the line of reflection is the same for both the pre-image and image.

If the line of reflection were different, the triangles would not be congruent.

Answer:

5 cases

10 additional units

Step-by-step explanation:

Given that:

Total number of units needed = 60 units

Total number of units per case = 14

Hence, the total number of cases required will

be: Number of units needed / number of units per

case

Number of cases required = 60/14 = 4.285 (this be up to 60 units)

means that 5 cases are required as 4 cases won't

With 5 cases, we have exceeded the required units needed:

Additional units will be: (145)-60

Additional units = 70 - 60 = 10 units

The identities in verifying the trigonometric expression sinx cosx tanx=1-cos^2x include:

tanx = sinx/cosx

sin^2x+cos^2x = 1

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous unique trigonometric identities that relate a triangle's side length and angle.

Anytime trigonometric functions are used in an expression or equation, trigonometric ifentities are helpful. For every value of a variable appearing on both sides of an equation, a trigonometric identity holds true. These trigonometric functions (such as sine, cosine, and tangent) of one or more angles are involved geometrically in these identities.

Based on the question, tanx = sinx/cosx and sin²x+cos^²x = 1 are applicable.

Based on the given parameters, the length of c is 8.0 units

The given parameters are

Angle c = 76 degrees

Side a = 20

Side b = 13

The length of c is then calculated using the following law of sines

c^2 = a^2 + b^2 - 2absin(C)

Substitute the known values in the above equation

So, we have

c^2 = 20^2 + 13^2 - 2 * 20 * 13 * sin(76)

Express 20^2 as 400

c^2 = 400 + 13^2 - 2 * 20 * 13 * sin(76)

Express 13^2 as 169

c^2 = 400 + 169 - 2 * 20 * 13 * sin(76)

Evaluate the product and sin(76)

c^2 = 400 + 169 - 520 * 0.9703

Evaluate the product

c^2 = 400 + 169 - 504.55

Evaluate the exponents

c^2 = 400 + 169 - 504.55

So, we have

c^2 = 64.45

Evaluate the square root

c = 8.0

Hence, the length of c is 8.0 units
