The maximum area is, A = 10.392

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 9-x²

first, Area = x × y

Area = x(9-x²)

Now,

the Domain: (0, 3)

Also, differentiating

A' = 0

9 - 3x² = 0

x²= 9/3

x =±3

So, the maximum area is

A= 1.732 x 6

A = 10.392

The longest piece of wood we need is the bottom left piece, which requires a board of at least 15 inches in length

Based on the dimensions provided in the image, we can see that Yeidalis needs a board that is at least as long as the longest piece of wood required.

The longest piece of wood required is the diagonal of the rectangle with dimensions 12 inches and 9 inches.

Using the Pythagorean theorem, we can calculate the length of this diagonal as:

sqrt(12^2 + 9^2) = sqrt(144 + 81) = sqrt(225) = 15 inches

So Yeidalis needs a board that is at least 15 inches long to create her artwork.

The phenomenon of being able to determine the true probabilities of events using a large number of trials is known as the law of large numbers.

The Law of Large Numbers states that in the long run, as the number of trials or observations increases, the observed relative frequencies of events will converge to the true probabilities.

It suggests that when an experiment is repeated a large number of times, the average or expected relative frequency of an event will approach its theoretical probability.

In other words, although the true probabilities of events cannot be determined with certainty based on a small number of trials, repeated trials or observations will result in more accurate and predictable relative frequencies.

Answer:

An acute triangle - interior angles are always less than 90 degrees with different side measures.

An obtuse triangle - one of the interior angles is more than 90 degrees. if one angle measures more than 90 degrees, then the sum of the remaining two angles is less than 90 degrees.

An right triangle -  a triangle with a right angle (90 degrees)

Equilateral triangle has three equal sides. Isosceles triangles has two equal side lengths. Scalene triangles has no equal side lengths

Answer:

45 degrees

Step-by-step explanation:

if <9 and <10 are corresponding, it means they are equal i.e <9 = <10

Since <9 and <10 are also complementary angles, their sum will be 90 degrees

<9+<10 = 90

<9 + <9 = 90

2m<9 = 90

m<2 = 90/2

m<2 = 45 degrees

Hence the measure of angle 9 is 45 degrees

So, the answer is a rectangular pyramid.

Therefore,  subscript indices must be either positive integers or logical. True

Explanation: The statement "subscript indices must be either positive integers or logicals" is true. Subscript indices are used to identify elements in an array. A positive integer subscript identifies a particular element in an array, while a logical subscript identifies a subset of elements based on a logical condition. For example, if we have an array A, then A(1) would identify the first element of the array, while A(A > 0) would identify all elements in the array that are greater than zero. Subscript indices cannot be negative or non-integer values.

Therefore,  subscript indices must be either positive integers or logical. True

The value of all sub-parts has been obtained.

(a). The total mass of the plate is 8g.

(b). Sketch of the plate has been drawn.

(c). The value of bar-x is 3/2.

What is area bounded by the curve?

The length of the appropriate arc of the curve is equal to the area enclosed by a curve, its axis of coordinates, and one of its points.

As given curve is,

y = x² for 0 ≤ x ≤ 2

From the given data,

The constant density of a metal plate is 3 g/cm². The metal plate as a shape bounded by the curve y = x² and the x-axis.

(a). Evaluate the total mass of the plate:

The area of the plate is A = ∫ from (0 to 2) y dx

A = ∫ from (0 to 2) x² dx

A = from (0 to 2) [x³/3]

A = [(2³/3) -(0³/3)]

A = 8/3.

Hence, the area of the plate is A = 8/3 cm².

and also, the mass is = area of the plate × plate density

Mass = 8/3 cm² × 3 g/cm²

Mass = 8g.

(b). The sketch of the required region shown below.

(c). Evaluate the value of bar-x:

Slice the region into vertical strips of width Δx.

Now, the area of strips = Aₓ(x) × Δx

                                      = x²Δx

Now, the required value of bar-x = [∫xδ Aₓ dx]/Mass

bar-x = [∫xδ Aₓ dx]/Mass.

Substitute values,

bar-x = [∫from (0 to 2) xδ Aₓ dx]/Mass

bar-x = [3∫from (0 to 2) x³ dx]/8

bar-x = [3/8 ∫from (0 to 2) x³ dx]

Solve integral,

bar-x = [3/8 {from (0 to 2) x⁴/4}]

bar-x = 3/8 {(2⁴/4) -(0⁴/4)}

bar-x = 3/8 {4 - 0}

bar-x = 3/2.

Hence, the value of all sub-parts has been obtained.

Answer:

-1/6 is the slope of a line perpendicular to that line

Step-by-step explanation:

Perpendicular lines always have opposite slopes

To find the slope of the perpendicular line you just have to find the opposite of the slope of this line.

First, you have to change the equation of that line to y=mx+b form to make it easier. You would just subtract 6x from both sides and you get y=6x-5

You see that the slope is 6 (or 6x) (this can also be written as 6/1 to make it easier)

The opposite of that is -1/6

The residual if you know the actual number is 3 and the predicted value is 1.6l is 1.4.

The residual is a measure of the difference between the predicted value and the actual value. In this case, the actual number is 3, and the predicted value is 1.6. To find the residual, we subtract the predicted value from the actual value:

Residual = Actual Value - Predicted Value

= 3 - 1.6

= 1.4

Therefore, the residual in this case is 1.4.

The residual represents the error or the amount by which the predicted value differs from the actual value.

A positive residual indicates that the predicted value is lower than the actual value, while a negative residual indicates that the predicted value is higher than the actual value.

In this case, the positive residual of 1.4 indicates that the predicted value of 1.6 underestimates the actual value of 3 by 1.4.

The 3/5 + 2/7 = 31/35, which is a ratio of two integers. This shows that 3/5 + 2/7 is rational.

To show that 3/5 + 2/7 is rational, we need to write it as a ratio of two integers. To do that, we must first find the common denominator of 5 and 7.5 x 7 = 35, 7 x 5 = 35.

Therefore, the common denominator is 35.Now, we need to write both fractions as an equivalent fraction with a denominator of 35. We can do that by multiplying each fraction by the denominator it is missing.

3/5 × 7/7 = 21/35 2/7 × 5/5 = 10/35

Therefore, 3/5 + 2/7 = 21/35 + 10/35We can add these two fractions because they have the same denominator, which gives us: 31/35
