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 justification for Step 1 is the subtraction property of equality. Option B

The justification for Step 1 within the arrangement prepare, which changes the condition 15x − 8 = 14x + 13 into 15x = 14x + 21, is the subtraction property of uniformity.

The subtraction property of equality states that in the event that we subtract the same amount from both sides of an condition, the condition remains genuine. In this case, we are subtracting 14x from both sides of the condition to confine the term with x.

To clarify Step 1 utilizing the subtraction property of correspondence:

The condition 15x − 8 = 14x + 13 is given.

We need to disconnect the x term on one side of the condition. To do this, we got to dispose of the 8 on the cleared out side.

By subtracting 14x from both sides of the condition, we evacuate the 14x term from the correct side:

15x − 14x − 8 = 14x − 14x + 13

Simplifying:

x − 8 = 13

Now, the 14x term is dispensed with from the proper side of the condition.

To advance streamline the condition, we are able include 8 to both sides to dispose of the -8 term on the cleared out side:

x − 8 + 8 = 13 + 8

Simplifying:

x = 21

Now, we have effectively isolated the x term on one side of the condition.

Therefore, the justification for Step 1 is the subtraction property of equality  (B).

Given:

The side lengths of a triangle are (4.5m - 2.7) centimeters, (9.4m + 4.2) centimeters,  and (5.3n +9.7) centimeters.

To find:

The perimeter of the triangle.

Solution:

Perimeter of the triangle is the sum of all side lengths of a triangle.

\(Perimeter=(4.5m-2.7)+(9.4m+4.2)+(5.3n+9.7)\)

On combining like terms, we get

\(Perimeter=(4.5m+9.4m)+5.3n+(4.2-2.7+9.7)\)

\(Perimeter=13.9m+5.3n+11.2\)

The perimeter of the triangle is (13.9m+5.3n+11.2) centimeters.

Therefore, the correct option is b.

Answer: its B

Step-by-step explanation:

4.5m-2.7+9.4m+4.2+5.3n+9.7

4.5m+9.4m+5.3n−2.7+4.2+9.7

13 buses are required.

Step-by-step explanation:

To find the number of minibuses required, take the total number of fans and divide by the number of fans each bus holds.

220 /18

12 2/9

We need to round up to make sure all the fans get on a bus.

13 buses are required.

Hence, 15 people out of 3 people can be chosen in 35 ways.

It is given that:

The total number of people in a race, n = 15

The number of finalists, r = 3.

Hence, the number of ways in which 3 people out of the 15 people can be finishers are:

\(^{15}C_{3} }\) = \(\frac{15!}{(15-3)!3!}\) = \(\frac{15!}{12!3!}\) = 35.

Hence, 15 people out of 3 people can be chosen in 35 ways.

2. Baker 2

3. Blend B

Step-by-step explanation:

1. 45/5= 9, but 14/2 = 7 so the ratio is 9:7 so obviosly Runner A is faster

2.     2: 3       1:2         2 = 2 x 1, but 2 x 2 is 4 so that means Baker # 2 used more flour.

3.      The ratio is 3:2 and 6: 5 . 3 x 2 = 6, which can be proportinal but 2 x 2 is not 5 and it should be 4 in order to be proportional but since 5 is greater than 4, Blend b has more milk per strawberry.

The given expressions, when A=1, B=0, and C=1, X evaluates to 1.001; when A=B=C=1, X evaluates to 1.111; and when A=B=C=0, X evaluates to 0.000. These evaluations are based on the given values of A, B, and C, and the notation ¯¯¯¯¯¯BC represents the complement of BC.

To evaluate the expression X = A.¯¯¯¯¯¯BC, we substitute the given values of A, B, and C into the expression.

(a) For A = 1, B = 0, and C = 1:

X = 1.¯¯¯¯¯¯01

To find the complement of BC, we replace B = 0 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯01 = 1.¯¯¯¯¯¯00 = 1.001

(b) For A = B = C = 1:

X = 1.¯¯¯¯¯¯11

Similarly, we find the complement of BC by replacing B = 1 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯11 = 1.¯¯¯¯¯¯00 = 1.111

(c) For A = B = C = 0:

X = 0.¯¯¯¯¯¯00

Again, we find the complement of BC by replacing B = 0 and C = 0 with their complements:

X = 0.¯¯¯¯¯¯00 = 0.¯¯¯¯¯¯11 = 0.000

In conclusion, when A = 1, B = 0, and C = 1, X evaluates to 1.001. When A = B = C = 1, X evaluates to 1.111. And when A = B = C = 0, X evaluates to 0.000. The evaluation of X is based on substituting the given values into the expression A.¯¯¯¯¯¯BC and finding the complement of BC in each case.

The Mean Value Theorem (MVT) is a theorem in calculus that relates the derivative of a function to the average rate of change of the function over a given interval.

The Mean Value Theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a number c in (a, b) such that:

f'(c) = (f(b) - f(a)) / (b - a)

To find all numbers c that satisfy the conclusion of the Mean Value Theorem, we need to check if the hypotheses of the theorem are satisfied, i.e. if the function is continuous on the closed interval and differentiable on the open interval.

Without the specific function and interval provided, we cannot determine all numbers c that satisfy the conclusion of the Mean Value Theorem. Please provide more information so we can help you better.

Since (∠2 ≅ ∠6) (corresponding angles)

The product of 8759 x 2391 x 2391 x 7759 is 388,895,526,171,961.

To find the product of 8759 x 2391 x 2391 x 7759, we can use the associative property of multiplication. This property states that the way in which we group the factors does not affect the result of the multiplication.

So, we can group the factors in pairs and multiply each pair together before multiplying the products. Let's start with 8759 x 7759 and then multiply the products of 2391 x 2391.

8759 x 7759 = 67,907,881
2391 x 2391 = 5,716,881

Now, we can multiply these two products together to get the final result.

67,907,881 x 5,716,881 = 388,895,526,171,961

Therefore, the product of 8759 x 2391 x 2391 x 7759 is 388,895,526,171,961.

Using the associative property of multiplication can make it easier to find the product of a large number of factors. By grouping the factors in pairs and multiplying each pair together, we can simplify the problem and make it more manageable.

The antiderivative of the given function x^-3 + 1/4√x is -1/2x^2 + 1/2x^(1/2).Therefore option C is correct.

To find an antiderivative of the given function x^-3 + 1/4√x:

We need to use the rules of integration.

We know that the antiderivative of x^n is (1/(n+1))x^(n+1) + C,

where C is the constant of integration.

We also know that the antiderivative of √x is (2/3)x^(3/2) + C.

So, let's break down the given function into two parts: x^-3 and 1/4√x.

The antiderivative of x^-3 is (-1/2)x^-2 + C.

The antiderivative of 1/4√x is (1/4) * (2/3)x^(3/2) + C

= (1/6)x^(3/2) + C.

Now, we can add these two antiderivatives together to get the antiderivative of the given function:

(-1/2)x^-2 + (1/6)x^(3/2) + C

Simplifying this expression, we get:

-1/2x^2 + 1/2x^(1/2) + C

The antiderivative of the given function x^-3 + 1/4√x is -1/2x^2 + 1/2x^(1/2).Therefore option C is correct.
