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

what is the length of the diagonal of the square shown below​

Answers

Answer:

7[tex]\sqrt{2}[/tex]

Step-by-step explanation:

the diagonal d divides the square into 2 right angles.

using Pythagoras' identity in one of the right triangles , then

d² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )

d = [tex]\sqrt{98}[/tex] = [tex]\sqrt{49(2)}[/tex] = [tex]\sqrt{49}[/tex] × [tex]\sqrt{2}[/tex] = 7[tex]\sqrt{2}[/tex]

Answer:

c =7√2

Step-by-step explanation:

using the Pythagorean theorem we solve the diagonal ,where the two sides are given to find the hypotenuse.

c² =a² + b²

where c is the diagonal (hypotenuse fot thr triangle)

a and b are the legs (sides)

c² =7²+7²

c²= 98

c= √98

c=√49.√2

c=7√2

What is Meant By Graphing Functions?

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 bought a computer scanner and supplies for $215.70, which will
allow him to scan images for $0.34 each. A computer center charges
$0.59 to scan each image. How many images must John scan before
his total cost is less than getting scanned images at the computer
center?

Answers

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.

A bucket of chicken had 12 pieces and cost $9.48. After 3pm it was on sale for $0.10 off per piece. What was the sale price per piece of chicken?

Answers

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

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

With f(x) being:

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

A dolphin swims 665,280 feet in 3 hours find the dolphin's rate in feet per hour.

Answers

Using the Speed-Distance-Time relation, the Dolphin's rate in Feet per hour is 221,760 ft/hr.

What is Speed-Distance-Time relation?Speed indicates how quickly something or someone is moving. If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed. The units in this example will be meters per second because the distance is measured in meters and the time is measured in seconds. Similar to an equation, the formula can be changed. We require the other two in order to calculate one of the variables. For instance, we need to know the length of the journey and the pace of movement in order to calculate the travel time.

Given, we have the distance travelled by dolphin is 665,280 feet and time is 3 hours.

s = d/t = 665.280/3 = 221,760 feet per hour

Answers

The probability that the number of the purple point is greater than the number of the green point, but less than twice the number of the green point is 1/4

How to find the Probability?

Let the "green" value be an x value lying on segment AC.

Now, the segment AC has the equation y = x. Then, let the "purple" value that is twice a selected x value lie on the segment AE and as such, the equation of this line is y = 2x.

It must be noted that at point E, x = 0.5 and y = 1. This means at every x value on AC greater than 0.5, the value of y on EC associated with this x value is is less than twice that x value.

Then, between segments AE and AC, every value of y will be greater than, but less than twice, its associated x value.

Since triangle ACD has an area of 1/2 and triangle BEA has an area of 1/4, then we can say that;

Triangle AEC area = 1 - (1/2) - (1/4)   = 1/4.
