The complete list of factor pairs for the constant term in this expression are

1 and 10, 2 and 5, −1 and −10, −2 and −5

The standard form of a quadratic equation is expressed as;

ax²+bx+c = 0

Given the quadratic equation x²−7x+10

To factor this expression, we need to get two values if when multiplied will give 10 (product of the coefficient of x²and the constant term) and the sum will give -7(coefficient of x).

The two values are:

-2 and -5

2 and 5

1 and 10

-1 and -10

The best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

The process of changing the value of one form to another is called conversion. It doesn't affects the value, it simply converts one form to another.

Now it is given that,

Width of a speck of dust = 8.2 x 10⁻⁷ m

Since, 1 kilometer = 1000 meters = 10³ meters

Therefore, 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷ x 10³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷⁺³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁴ kilometer

Thus, the best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

Answer:

-95

Step-by-step explanation:

The solution is -95

The value of the equation A = -16 + ( -76 ) is A = -95

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = the sum of -19 and -76

On simplifying the expression , we get

A = ( -19 ) + ( -76 )

On simplifying the equation , we get

A = -19 - 76

The value of A = -95

Therefore , the value of A is -95

Hence , the solution of sum of -19 and -76 is -95

Exponential Function has the following characteristics:

Determining the nature of the function

Given the table

x    0     2      4       6

y     0     4      8       16

Linear Function has the following characteristics:

The constant change in x and y

Checking the constant change in x

i.e. 2-0 = 2, 4-2 = 2, 6-4 = 2

Thus, there is a constant change in x values.

Checking the constant change in y

4-0 = 4, 8-4 = 0, 16-8= 8

Thus, there NO constant change in y values.

Therefore, the given function DOES NOT represent the linear function.

Determining if the given function is Exponential function or not.

CHECKING THE CONSTANT CHANGE IN X VALUE

i.e. 2-0 = 2, 4-2 = 2, 6-4 = 2

Thus, there is a constant change in x values.

Checking the CONSTANT RATIO

4/0=∞, 8/4 = 2, 16/8 = 2

It is clear that there is no constant ratio.

Therefore, the given function DOES NOT represent the exponential function.

Conclusion:

Thus, the given function neither represents the linear function nor represents an exponential function.

Answer:

8 cm

Step-by-step explanation:

A circle with center B and radius 13 cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA is perpendicular to BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.

Solution:

Since the radius of the circle is 13 cm, hence:

BF = BD = BE = 13 cm.

For line segment BE; BE = BC + CE

BE = BC + CE

13 = BC + 1

BC = 13 - 1

BC = 12 cm

AD = BC = 12 cm (opposite sides of a rectangle are equal to each other)

Triangle ABD, is a right angled triangle because ∠B = 90°. We can use Pythagoras theorem to find AB:

BD² = AB² + AD²

13² = AB² + 12²

169 = AB² + 144

AB² = 169 - 144

AB² = 25

AB = √25 = 5

For line segment BF, we can use the line segment addition postulate to find the distance from A to F. Let x be the distance from A to F:

BF = AB + x

x = BF - AB

x = 13 - 5

x = 8 cm

Step-by-step explanation:

we have to keep 5 rather than x

the answer is 36

Answer:

$30.00

Step-by-step explanation:

Percentage Markup formula =

Selling price - Cost price/Cost price × 100

From the question:

Cost price = $12.50

Selling price = unknown = x

Percentage Markup = 140%

140% = x - $12.50/$12.50 × 100

140/100 = x - $12.50/$12.50

1.4 = x - $12.50/$12.50

Cross Multiply

1.4($12.50) = x - 312.50

$17.50 = x - $12.50

x = $17.50 + $12.50

x = $30.00

Therefore, the selling price of the purse is $30.00

Step-by-step explanation:

Look at the graph they gave you. ... At first it looks like an ugly mess.

But look closer.  There are only two lines there that go through the origin,

so one of those is the answer to the question.

Now let's talk about the slope of a line.

-- If the slope of a line is positive, that means it rises as it goes.

  If you walk the graph from left to right, you're climbing.

-- If the slope of a line is negative, that means it falls as it goes.

  If you walk the graph from left to right, you're going down-hill.

The equation they gave you is  [ y = 1/2 x ].

The slope is  1/2 .  That's positive.

The line on the graph slopes up.  To walk it, you have to climb.

In the picture, that can only be line 'c' .

Answer:

Answer/Step-by-step explanation:

a. The order pair are:

(1, 6) => when x (distance) = 1, y (price) = 6

(3, 8) => when x (distance) = 3, y (price) = 8

(5, 10) => when x (distance) = 5, y (price) = 10

(7, 12) => when x (distance) = 7, y (price) = 12

{(1, 6) (3, 8), (5, 10), (7, 12)}

b. The graph represents a function because every domain value (x-value) has only one range value (y-value) that is related to each.

2.5 m/s

Step-by-step explanation:

Matty's speed = 9 km/hr

We need to convert 9 km/hr to m/s

We know that,

1 km = 1000 m

1 hour = 3600 seconds

[tex]v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s[/tex]
