Step-by-step explanation:

The standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is 0.7304 x [tex]10^{1}[/tex].

Given,

7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 )

We need to write this large number in standard form.

A standard form is a way of expressing a large number as a decimal number between 0 and 1 (including 1) and multiplied by a power of 10.

We have,

7 x 1 + 3 x ( 1 / 10 ) + 4 x ( 1 / 1000 )

7 + 0.3 + 0.004

7.304

Since we need a decimal point between 0 and 1.

We will multiply 7.304 by 10 / 10.

so we have,

7.304 x 10 / 10

(7.304 / 10 ) x 10

0.7304 x 10

Remember that a number to the power 1 is the number itself.

[tex]10^{1} = 10[/tex]

We see that in 0.7304 x [tex]10^{1}[/tex],

0.7304 is a decimal point between o and 1 and we have a power of 10.

It satisfies the standard form of a number.

Thus the standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is

0.7304 x [tex]10^{1}[/tex].

but

[tex] {1}^{0} = 1[/tex]

now adding the results for that one also

2+2+2 +1=7

adding the total for all

6+7= 13

Final answer:

The sum of the binary numbers 110two and 111two is 1101two, which is equivalent to 13 in decimal form.

Explanation:

The question asks for the sum of two binary numbers: 110two and 111two. To add these two binary numbers, we align them by their least significant bits and perform binary addition:

110

+ 111

-----

1101

This is equivalent to the decimal addition of 6 (110two) + 7 (111two) which equals 13. In binary, 13 is represented as 1101two.

Answer:

4(b-6)=b^2

Step-by-step explanation:

The difference would mean that it is subtraction and you multiply that difference by 4 and set it equal to b squared

According to the statement, the given equation is  4(b - 6) = b², and the value of b is 2 + 4.472i and 2 - 4.472i.

To solve the equation given: 4(b - 6) = b², we need to first expand and simplify.

4b - 24 = b²

b² - 4b + 24 = 0

b = 2 + 4.472i and 2 - 4.472i.

thank you for your time!

Step-by-step explanation:

In Mathematics, the order of operations (BOMDAS or BIDMAS) dictates that multiplication operations should be performed before addition. Hence, in the mathematical expression '80 + 80 equals 80 + 80 * 80 equals', the multiplication operation (80*80) is performed first, resulting in '80 + 6400 = 6480'. Therefore, 80 + 80 equals 6480.

In Mathematics, the operation order matters, this order is known by the acronym BOMDAS or BIDMAS, which stands for Brackets, Orders, Multiplication and Division, and Addition and Subtraction. it is used to clarify which procedures should be performed first in a given mathematical expression.

In your question, '80 + 80 equals 80 + 80 * 80 equals', we have both addition and multiplication operations. According to BIDMAS rules, we perform multiplication first before addition. Hence, the given expression is equivalent to 80 + 80 equals 80 + (80 * 80), where (80*80) should be calculated first.

Putting this into practice, we get: 80 + (80 * 80) = 80 + 6400 = 6480. Therefore, 80 + 80 equals 6480, based on the principles of BIDMAS or BOMDAS.

Answer:

SORRY DONT KNOW

Step-by-step explanation:

the measure of angle ∠21 must be 55 degrees for line b to be parallel to line a.

In order for line b to be parallel to line a, the measure of angle ∠21  must be 125 degrees. Corresponding angles are angles that are in the same position relative to two intersecting lines. Since lines a and b are parallel, we know that corresponding angles ∠1 and ∠21 are congruent.  Therefore, we can set up the following equation to find the measure of ∠21:

∠1 + ∠21 = 180° (because they are supplementary angles)

Substituting 125° for the measure of ∠1, we get:

125° + ∠21 = 180°

Solving for ∠21, we get:

∠21 = 180° - 125°

∠21 = 55°

cancel equal terms on both sides of the equation

the statement is true but only if both sides equal 0

solve the equation for x

divide both sides of the equation by 4

when the absolute value of x - 9 equals 0, then x - 9 = 0

Step-by-step explanation:

The domain of the function F(x) = √(x+4) is all real numbers greater than or equal to -4, which corresponds to option C. x≥-4.

The student has asked about the domain of the function F(x) = √(x+4). To determine the domain of this function, we need to consider the values of x for which the expression under the square root, x+4, is non-negative, since the square root of a negative number is not defined in the set of real numbers.

The expression x+4 is non-negative when x ≥ -4. Therefore, any number greater than or equal to -4 is part of the domain of the function.

This means the correct answer to the question is C. x≥-4.
