Then ,their product −52 d² is negative .

Answer:

103000

Step-by-step explanation:

3.5 × \(10^{4}\) + 6.8 × \(10^{4}\)

Calculate 10 to the power of 4 and get 10000.

3.5 × 10000 + 6.8 × \(10^{4}\)

Multiply 3.5 and 10000 to get 35000.

35000 + 6.8 × \(10^{4}\)

Calculate 10 to the power of 4 and get 10000.

35000 + 68000

Add 35000 and 68000 to get 103000.

Answer:

Couple of choice:

A. If those x's are the multiplication symbol then your answer is 103,000

B. If those x's are variables then you don't have a definite answer.

Step-by-step explanation:

Explanation for A:

We use PEMDAS and start inside the parentheses

We do exponents before multiplication and get 10,000 for 10^4

10,000*3.5= 35,000

10,000*6.8=68,000

35,000+68,000=103,000

Explanation for B:

If the x's are variables then your question is just and expression. Without it being equal to anything, I can't solve for x. Also if the question was asked as, "What is (3.5x10^4)+(6.8x10^4), when x = 5 (or any random number)" I could solve it because I know the value of x being asked.

Answer:

Which circumstance led the Confederacy to think that it could purchase weaponry and supplies to use in the Civil War?

A.  

increased taxation on Southern states

B.  

support from Britain and France

C.  

an abundance of cotton in the Southern states

D.  

profits from the large number of industries

Step-by-step explanation:

The number of inches by which each dimension must be increased is 10 inches.

Let length and width be increased by x.

so we get, the length = (10 + x) and breadth = (5 + x)

(10 + x)(5 + x) = 6 × 10 × 5

50 + 10 x + 5x + x² = 300

x² + 15x- 250 = 0

x² + 25x- 10x - 250 = 0

x  (x + 25) - 10 (x + 25) = 0

(x + 25)(x - 10) = 0

x = -25 is not the right choice as length cannot be negative.

so x = 10

so both dimensions should be increased by 10 inches.

Answer:

D. 2x² + 10x - 2

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Length = x² + 3x - 2

Width = 2x + 1

Perimeter = 2(x² + 3x - 2 + 2x + 1)

Perimeter = 2(x² + 5x - 1)

Perimeter = 2(x²) + 2(5x) - 2(1)

Perimeter = 2x² + 10x - 2

The solution to the equation -2(x + 3) = -6 is x = 0.

To simplify the expression 5t + 7 + 8b, we can combine like terms.

There are two like terms in the expression: 5t and 8b.

Combining the like terms gives us:

5t + 8b + 7

Therefore, the simplified form of the expression 5t + 7 + 8b is 5t + 8b + 7.

Regarding the equation -2(x + 3) = -6:

To solve this equation, we can follow these steps:

Distribute the -2 to the terms inside the parentheses:

-2 * x + (-2) * 3 = -6

This simplifies to:

-2x - 6 = -6

Move the constant term to the right side by adding 6 to both sides of the equation:

-2x = 0

Divide both sides of the equation by -2 to isolate the variable x:

x = 0 / -2

Simplifying the right side of the equation gives us:

x = 0

The solution to the equation -2(x + 3) = -6 is x = 0.

The simplified expression 5t + 7 + 8b remains as 5t + 8b + 7, and the solution to the equation -2(x + 3) = -6 is x = 0.

Then it will take approximately 6.3 hours for the culture to grow to 80,000 bacteria

The given formula for the number of bacteria in a culture after t hours is:y = 5000(3)^tWe are required to find the number of hours it will take the culture to grow to 80,000.

This can be done by setting y equal to 80,000 and then solving for t.5000(3)^t = 80,000

Divide both sides by 5000:3^t = 16Now, we need to solve for t by taking the logarithm of both sides.

However, it is easier to use logarithmic properties to simplify the equation first.3^t = 2^4

Raise both sides to the power of (1/log3):log3(3^t) = log3(2^4)t = 4/log3(2)Using a calculator, log3(2) ≈ 0.631, so:t ≈ 4/0.631 ≈ 6.3.

The hypotenuse of a right triangle will be $561$.

What is hypotenuse?

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.

Lengths of legs of a right triangle are given that are $264$ and $495$.

According to The Pythagorean Theorem,

\(hypotenuse^{2} = lenght^{2} + lenght^{2}\\hypotenuse^{2} = 264^{2} + 495^{2}\\\\hypotenuse^{2} = 69,696 + 245,025\\ hypotenuse^{2} = 314,721\\hypotenuse = 561\)

Step-by-step explanation:

Answer: 21

h(-8)= 4|(-8)+2| -3             do what's inside absolute value first

=4(6)-3                             multiply

=24-3                               subtract

=21

The computation of the equations is illustrated below.

a. x - y = 1 .... i

x + y = -9 ..... ii

Subtract the equations

-2y = 10

y = 10/-2 = -5

Since x - y = 1

x - (-5) = 1

x + 5 = 1

x = 1 - 5 = -4

b. 3x + 2y = -9

x - y = -13

Multiply equation i by 1

Multiply equation ii by 3

3x + 2y = -9

- 3x - 3y = -39

5y = 30

y = 6

Since x - y = 13

x - 6 = 13

x = 13 + 6 = 19

The area of the square with a side length of 3.1 meters is 9.61 square meters.

To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.

Area of a square = side length × side length

Substituting the given side length into the formula:

Area = 3.1 m × 3.1 m

To perform the calculation:

Area = 9.61 m²

It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.

Remember, to find the area of any square, you simply need to multiply the length of one side by itself.
