Answer:

"We can't use any of the patterns"

Step-by-step explanation:

You can't use [tex](U+V)^2[/tex] because that would result in some stuff in the middle. In general if you have something like that it would expand to [tex]U^2+2UV + V^2[/tex]. and same thing for the (U-V)^2 except the middle would be a negative number. You also can't use [tex](U+V)(U-V)[/tex] because it specifies "constant integers" and the "integer" part is what's really important, because you can technically rewrite the sum of squares as (U + V)(U - V) but you would need to use imaginary numbers. Because the difference of squares is defined as [tex]a^2-b^2 = (a-b)(a+b)[/tex]. But you can also think of it like this [tex]a-b = (\sqrt{a} - \sqrt{b})(\sqrt{a}+\sqrt{b})[/tex] because that's essentially what the original identity is saying. Using this definition you can write the sum of squares as [tex]a+b = a - (-b) = (\sqrt{a} + \sqrt{-b})(\sqrt{a} - \sqrt{-b}) = (\sqrt{a} + i\sqrt{b})(\sqrt{a} - i\sqrt{b})[/tex]. So with the restriction of constant integers "We can't use any of the patterns" is the correct answer

Answer: 25,0.

Step-by-step explanation:

∡B=27°     ∡C=82°      b=12      a=?

∡A=180°-(27°+82°)=180°-109^°=71°.

[tex]\frac{a}{sinA} =\frac{b}{sinB} \\a=\frac{b*sinA}{sinB}=\frac{12*sin71^0}{sin27^0}=\frac{12*0,9455}{0,454} \approx25,0[/tex]

Answer: -5/21.

Step-by-step explanation:

[tex]\frac{2}{5}*[\frac{-3}{7} +(\frac{-1}{6})]=\frac{2}{5} *(-\frac{3}{7} -\frac{1}{6}) =\frac{2}{5}*(-\frac{3*6+1*7)}{7*6} )=\frac{2}{5}*(-\frac{18+7}{42})=\frac{2}{5}*(-\frac{25}{42})=-\frac{5}{21} .[/tex]

Answer:

Step-by-step explanation:

Based on the polynomial function given, the lower bound can be found to be -14.

With f(x) being:
= x⁴ - 4x³ + 9x² - x - 14

Then f'(x) will be:
= 4x³ - 12x² + 18x - 1

If f'(x) is 0:

0 = 4x³ - 12x² + 18x - 1

x = 0.0578

So:
f(0.05) = -14.028

The lower bound is therefore -14.

The total dollar amount of sales is $150,000

What is the sales amount achieved by the salesman to earn a commission of $3,000?

To compute the portion of total sales earned as commission, we simply  multiply the sales amount recorded  by the percentage of commission which is 2%

sales commission=sales amount*commission rate

sales commission=$3,000

sales amount=unknown(assume it is X)

commission rate=2%

$3,000=X*2%

Graphing functions is drawing the curve that represents the function on the coordinate plane. If a curve (graph) represents a function, then every point on the curve satisfies the function equation.

According to the question,

The following graph represents the linear function f(x) = x -2

Take any point on this line, say, (-1, 3).

Let us substitute (-1, 3) = (x, y) (i.e., x = -1 and y = 3) in the function f(x) = -x + 2 (note that it can be written as y = x - 2).

Then

3 = -(-1) + 2

3 = 1 + 2

3 = 3, thus, (-1, 3) satisfies the function.

In the same way, you can try taking different points and checking whether they satisfy the function. Each and every point on the line (in general called "curve") satisfies the function.

John must scan more than 862 images before his total cost is less than getting scanned images at the computer center.

To determine how many images John must scan before his total cost is less than getting scanned images at the computer center, we can set up an equation.

Let's denote the number of images John needs to scan as "x."

The total cost for John to scan x images is given by:

John's total cost = cost of scanner + cost of supplies + cost per image scanned

John's total cost = $215.70 + ($0.34 * x)

The total cost for scanning x images at the computer center is given by:

Computer center's cost = cost per image scanned * x

Computer center's cost = $0.59 * x

We want to find the point at which John's total cost is less than the computer center's cost. In other words, we want to find the value of x for which John's total cost is less than the computer center's cost:

John's total cost < Computer center's cost

$215.70 + ($0.34 * x) < $0.59 * x

Now, we can solve for x:

$215.70 + ($0.34 * x) < $0.59 * x

$215.70 < $0.59 * x - $0.34 * x

$215.70 < $0.25 * x

Divide both sides of the inequality by $0.25:

$\frac{215.70}{0.25} < \frac{0.25 * x}{0.25}$

862.80 < x

Therefore, John must scan more than 862 images before his total cost is less than getting scanned images at the computer center.

The system of linear inequalities to represent this situation. is given as-

9p <= 480

a >= 8s

p = a + s

Expressions with linear inequalities compare any two values using inequality symbols like "<," ">," "<=," or ">=." These values could be either numerical, algebraic, or both.

If the linear inequality is larger than or less than but not equal to, a dashed line appears on the graph. On the other hand, a solid line always appears in linear equations. Linear equations lack shaded sections, whereas linear inequalities do.

According to the question,

The buses can carry a maximum of 480 people.

These people include adults as well as students.

Let 'p' represents the total number of people in the bus.

Let 'a' represents the number of adults in the bus.

Answer:

The sale price per piece of chicken was $0.69

Step-by-step explanation:

• We have to first calculate the price of 1 piece of chicken when 12 pieces cost $9.48.

Original price per piece = $9.48 ÷ 12

                                        = $0.79

• According to the question the price per piece decreased by $0.10 during the sale.

∴ Sale price per piece = $0.79 - $0.10

                                     = $0.69
