Which statement about histograms is true?
Data is organized in categories.
Data appears as bars that are all about the same height.
Data is organized in equal intervals.
Data appears as bars that do not touch.

Answer:

(x + 7)/(x - 3)

Step-by-step explanation:

To simplify this expression, we first factor the numerator and denominator, and then cancel any common factors:

x² + 3x - 28 = (x + 7)(x - 4)

x² - 7x + 12 = (x - 3)(x - 4)

So the expression simplifies to:

(x + 7)(x - 4) / (x - 3)(x - 4)The (x - 4)

factor in both the numerator and denominator cancels out, leaving:

x + 7 / x - 3

Therefore, the simplified expression is (x + 7)/(x - 3)

The correct statement comparing the values of the 8s in 2,7812 and 94894 is that the 8 in 2,7812 has a greater value than the 8 in 94894.

This is because the value of a digit in a number is determined by its place value. In the number 2,7812, the 8 is in the hundreds place, meaning it has a value of 800. In the number 94894, the 8 is in the tens place, meaning it has a value of 80.

Therefore, the 8 in 2,7812 has a greater value (800) than the 8 in 94894 (80).

Answer:

17 years & 9 months

Step-by-step explanation:

annual rate 3.9%

every quarter = 3.9%/4 = 0.98%

compounding every quarter = (1+0.98%)

how long = assuming t quarters

2000 * (1+0.98%) ^t = 4000

solve for t

t= 71

so 71/4 = 17 years & 9 months

The equation which can be used to represent the situation is 396 = x - 0.2x

The original price of the love seat was $495.

Let

Original price of the love seat= x

New price= $396

Percentage discount= 20%

396 = x - (20% of x)

396 = x - 0.2x

396 = 0.8x

divide both sides by 0.8

x = 396 / 0.8

x = $495

The company produce each month to maximize their profit be (50, 100000).

To ensure the best output and price levels are realized in order to maximize returns, business firms engage in the process of profit maximization. In order to achieve its profit objectives, the company modifies important variables including sale price, production costs, and output levels.

"Profit maximization" emphasizes the location of this critical point, or the optimal output at which your company is most profitable. An educational non-profit organization called Khan Academy states that "a corporation striving to maximize profit will produce the quantity where 'marginal cost' and 'marginal income' are equal to each other."

Let x be the number of ceiling fans

If the price per fan when you sell x fans exists (300 - 2x), then the amount received for selling x fans exists x(300 - 2x)

The cost for producing x fans is (20x + 100).

Profit = x(300 - 2x) - (20x + 100)

y = (1000 + 20x)(300 - 2x)

simplifying the equation, we get

y = 300000 - 2000x + 6000x - 40x²

y = -40x² + 4000x + 300000

simplifying the above equation, we get

Answer & Step-by-step explanation:

To get the range of the function y = 2x + 1, we need to determine the set of all possible output values (y) that the function can produce for the given domain.

When x = -2, y = 2(-2) + 1 = -3.

When x = 4, y = 2(4) + 1 = 9.

When x = 6, y = 2(6) + 1 = 13.

So, the output values (y) for the given domain { -2, 4, 6 } are -3, 9, and 13.

Answer: The transformation matrix R for a rotation of 120° about an axis from the origin through the point (1,1,1) can be calculated using the formula:

R = I + (sin(θ))U + (1-cos(θ))UU'

where θ is the angle of rotation (120° in this case), I is the identity matrix, U is a skew-symmetric matrix, and U' is its transpose. The skew-symmetric matrix can be calculated as follows:

U = [0, -z, y; z, 0, -x; -y, x, 0]

where x, y, and z are the components of the vector (1,1,1) that defines the axis of rotation.

Plugging in the values and simplifying, the transformation matrix R is:

R = [ cos(120°), -sin(120°), 0; sin(120°), cos(120°), 0; 0, 0, 1 ]

Note: cos(120°) = -1/2 and sin(120°) = √(3)/2.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

12 > 2x + 4

Now, if we put x= 8 then

So, x=8 is not true

Now,  if we put x= 4 then

= 2x+ 8

= 2(4)+8

So, x=4 is not true

Now,  if we put x= 12 then

So, x=12 is not true

First, we need to find out how many 1200 sq ft portions the 4800 sq ft lawn is:

4800 sq ft / 1200 sq ft/portion = 4 portions

Therefore, the architect will need 12 lb of seed.

The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is the sum of the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied.

The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is calculated by summing the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied. Momentum is a vector quantity which is equal to the product of the mass and velocity of an object. In this case, the t-shirt has a mass of 4 kg and a velocity of 4 m/s. The force of 15 N applied to the t-shirt for 3 seconds causes the t-shirt to accelerate, increasing its velocity from 4 m/s to 8 m/s. This increase in velocity results in an increase in the momentum of the t-shirt from 2 kg⋅m/s to 17.5 kg⋅m/s. Thus, by calculating the change in momentum due to the applied force, we can determine the final momentum of the t-shirt.
