Step-by-step explanation:

The building's dimensions would be 22.5 inches by 12.5 inches on the drawing when the scale of 1 inch represents 10 feet.

The dimensions of the building you have mentioned are 225 feet by 125 feet. Given the scale of 1 inch represents 10 feet, we can calculate the dimensions of the building on the drawing by dividing each dimension of the building by the scale factor.

So, for the first dimension: 225 feet divided by 10 (scale factor) equals 22.5 inches. For the second dimension, 125 feet divided by 10 equals 12.5 inches.

Therefore, the dimensions of the building on the drawing would be 22.5 inches by 12.5 inches.

Answer:

[tex]f(x)=2x^3+x[/tex]

Step-by-step explanation:

An odd function f is one where [tex]f(-x)=-f(x)[/tex]. We can interpret this is meaning: reflecting the graph horizontally [tex]f(-x)[/tex] has the same effect as reflecting it vertically [tex]-f(x)[/tex] . The only graphs that meet this requirement are ones with reflectional symmetry across the line y = x, so we can immediately elimate the functions [tex]f(x)=3x^2+7[/tex] and [tex]f(x)=5x^2-6[/tex], which have horizontal symmetry, but not the kind of symmetry we're looking for.

That leaves us with [tex]f(x)=2x^3+x[/tex] and [tex]f(x)=4x^3+2x^2[/tex]. One feature of exponents we can utilize is that -1 to an even power is 1, while -1 to an odd power is -1. If we want [tex]f(-x)=-f(x)[/tex], we need to flip the signs of all the coefficients, and we can only do that if all the powers of x are odd. The only function with only odd powers of x is [tex]f(x)=2x^3+x[/tex], and plugging in -x to the function reveals that

[tex]f(-x)=2(-x)^3+(-x)\\f(-x)=-2x^3-x=-(2x^3+x)=-f(x)[/tex]

So [tex]f(x)=2x^3+x[/tex] the only odd function on the list!

Answer:

Step-by-step explanation:

Let one of the side = x

So, other side = x - 2

Area = 360 sq.m

x*(x - 2) = 360

x*x - x * 2 = 360

x² - 2x -360 = 0

x² + 18x - 20x  - 18*20 = 0

x(x +18) - 20*(x + 18 ) = 0

(x + 18)(x -20) = 0

{x + 18 is ignored as measurement will not be a negative number}

x - 20 = 0

x = 20

Length of the longer side = 20 m

Final answer:

To evaluate the expression x^3 + x^2 for x=4, you substitute 4 into the equation, resulting in 4^3 + 4^2, which is 64 + 16, equalling 80.

Explanation:

The question asks to evaluate the expression x^3 + x^2 for x=4. To do this, we simply substitute 4 into the expression.

First, calculate 4 to the power of 3 (4^3), which is 64. Next, calculate 4 to the power of 2 (4^2), which is 16. Finally, add these two results together: 64 + 16 = 80.

Therefore, x^3 + x^2 evaluated for x=4 is 80.

To evaluate the expression x^3 + x^2 for x=4, substitute the value of x into the expression, resulting in 4^3 + 4^2, which simplifies to 64 + 16, and the final answer is 80.

To evaluate the expression x^3 + x^2 for x=4, we need to substitute the value of x into the expression and simplify it. Firstly, we calculate x to the power of 3, which is 4^3, and x to the power of 2, which is 4^2.

4^3 = 4 × 4 × 4 = 64

4^2 = 4 × 4 = 16

Now, we add the results together:

64 (which is 4^3) + 16 (which is 4^2) = 80

Therefore, when we evaluate the expression for x=4, the result is 80.

The correct answer is B) Yolanda should have found the volume by multiplying 8 by Four-thirds.

Yolanda incorrectly used the formula for volume of a sphere instead of the correct formula. The volume of a sphere is V = (4/3)πr³, not V = four-thirds(8) cubed.

By using the correct formula, Yolanda should have multiplied 8 by four-thirds to find the volume of the sphere, resulting in a different value.

Answer:

4x  +6

Step-by-step explanation:

(x+4) + (3x+2)

Combine like terms

x+3x   +4+2

4x  +6

To find the sum of the expressions (x+4) and (3x+2), one combines like terms. The sum of the x terms, 1x and 3x, is 4x and the sum of the constants, 4 and 2, is 6. Hence, the sum of the given expressions is 4x + 6.

To find the sum of two expressions, (x+4) and (3x+2), we need to follow a process known as combining like terms. In arithmetic and algebra, 'like terms' are terms that have the same variables and powers. In this case, the 'like terms' are x in (x+4) and 3x in (3x+2).

Adding these two expressions, we get:

(x + 4) + (3x + 2)

To combine like terms, we add the coefficients of the x terms together (1x and 3x) and we add the constants together (4 and 2).

Sum of x terms: x + 3x = 4x

Sum of constants: 4 + 2 = 6

So, the sum of (x + 4) and (3x + 2) is 4x + 6.

Answer:

A.)

Two x-intercepts

Step-by-step explanation:

This question pertains to determining the number of x-intercepts a given quadratic equation has. To solve this, the discriminant of the quadratic equation would need to be calculated, which subsequently determines the number of x-intercepts (if repeated D>0 equals two, D=0 equals one and D<0 means none). The exact number for this specific equation could not be calculated due to an unclear part in the question.

The equation y = 0.5x^2 -6x + 3 is an equation of a quadratic function. The x-intercepts of this function can be found by setting y to 0 and solving the equation for x. A quadratic equation, however, can have two, one, or no x-intercepts, depending on its discriminant (D). The discriminant is found with the equation D = b^2 - 4ac from the general form of a quadratic equation which is ax^2+bx+c = 0. If D > 0 the quadratic has two x intercepts, if D = 0 then it has exactly one and if D < 0 it has none.

For our equation (0,5x^2-6x+3), the discriminant (D) could be calculated as: D = (6)^2 - 4*(0,5)*3. After this calculation, we could determine the number of x-intercepts but since this is not fully clarified in the question, we can't provide a definite answer.

Answer:

D. $2,511

Step-by-step explanation:

First off, we need to write down the facts we know.

There are about 52.177 weeks in a year

Cesar works 28 hours each week

Cesar makes $23 an hour

There are 12 months in a year

Cesar has $3,360 after his monthly expenses

To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses.

Cesar's average monthly expenses, rounded to the nearest dollar, were $2,511.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Cesar worked every week for the year, which is 52 weeks.

Therefore,

He worked a total of 52 x 28 = 1,456 hours.

If he made $23 an hour, then his total earnings for the year would be

1,456 x $23 = $33,488.

If he saved $3,360 after paying all of his monthly expenses, then his total expenses for the year would be:

$33,488 - $3,360 = $30,128

To find his average monthly expenses, we can divide his total expenses for the year by 12:

= $30,128 ÷ 12

= $2,510.67

Rounding this to the nearest dollar, we get an answer of $2,511

Therefore,

Cesar's average monthly expenses, rounded to the nearest dollar, were $2,511.

Answer:

0.25

Step-by-step explanation:

1/2 the cards are red and 1/2 are black so it is 0.5 x 0.5

The probability that the first card drawn is a black card and the second is a red card, with replacement, is 1/4 or 25%.

In probability, when we talk about selecting cards with replacements from a deck, the chances of any single card being drawn remain constant regardless of previous draws. A standard deck of cards has 26 black cards and 26 red cards. The probability of drawing a black card is P(Black) = 26/52, and similarly, the probability of drawing a red card is P(Red) = 26/52. When we draw one card, replace it, and then draw again, the outcomes are independent since the replacement restores the deck to its initial state.

The probability of the first card being black and the second card being red is the product of the individual probabilities of each event:

Therefore, the probability that the first card drawn is black and the second is a red card is 1/4 or 25%.
