Answer:

[tex]y=8(5)^x[/tex]

Step-by-step explanation:

We want an exponential function that goes through the two points (0, 8) and (2, 200).

Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

[tex]8=a(b)^0[/tex]

Simplify:

[tex]a=8[/tex]

So we now have:

[tex]y = 8( b )^x[/tex]

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

[tex]200=8(b)^2[/tex]

Solve for b. Dividing both sides by 8 yields:

[tex]b^2=25[/tex]

Thus:

[tex]b=5[/tex]

Hence, our exponential function is:

[tex]y=8(5)^x[/tex]

Answer:

[tex]y = 8(5) {}^{x} [/tex]

Step-by-step explanation:

The normal exponential function is in form

[tex]y = ab {}^{x} [/tex]

let plug in 0,8

[tex]8 = ab {}^{0} [/tex]

b^0=1

so

[tex]8 = a \times 1 = \: \: \: \: a = 8[/tex]

So so far our equation is

[tex]y = 8b {}^{x} [/tex]

So now let plug in 2,200

[tex]200 = 8b {}^{2} [/tex]

Divide 8 by both sides and we get

[tex]25 = b {}^{2} [/tex]

[tex] \sqrt{25} [/tex]

Which equal 5 so b equal 5. So our equation is

[tex]y = 8(5) {}^{x} [/tex]

Is the question complete??

The slope intercept form of the equation x + 6y - 2 is y = -x/6 + 1/3.

When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.

Here m is slope and c is constant.

The given equation is,

x + 6y = 2,

To find the slope intercept form of the equation,

Solve the equation,

6y = -x + 2

y  = -x/6 + 2/6

y = -x/6 + 1/3

The slope intercept form of the equation is y = -x/6 + 1/3.

Answer: 2880 flowers

Step-by-step explanation:

Since 648 flowers were arranged in 27 large vases, with the same number in each vase, this means that each vase will contain 24 flowers

= 648/27

= 24 flowers

Therefore, the number of flowers needed to fill 120 vases will be:

= 24 × 120

= 2880 flowers

Answer:

side length of the smaller room = 5 m

Side length of the larger room = 8 m

Step-by-step explanation:

Total area of two square room = 89 m²

Area of a square = side²

Let

x = side of the smaller square

x + 3 = side of the longer square

Total area = area of room A + Area of room B

89 = x² + (x + 3)²

89 = x² + x² + 6x + 9

89 - 9 = 2x² + 6x

2x² + 6x = 80

2x² + 6x - 80 = 0

Divide through by 2

x² + 3x - 40 = 0

Solve quadratic equation using factorization method

x² + 8x - 5x - 40 = 0

x(x + 8) -5(x + 8) = 0

(x - 5) (x + 8) = 0

(x - 5) = 0 (x + 8) = 0

x = 5 x = -8

The side length of a square room can not be a negative value

Therefore, side length of the smaller room = 5 m

Side length of the larger room = 5 + 3

= 8 m

Answer:

Answer A=48

Step-by-step explanation:

Took the test got it right.

The expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

Given is the expression as -

(2w - 2)³ × (8w⁶)

The given expression is -

(2w - 2)³ × (8w⁶)

{2(w - 2)}³ × (8w⁶)

8(w - 1)³ × (8w⁶)

(a+b)³ = a³ - 3a²b + 3ab² - b³

So, on expanding, we will get -

8(w³ - 1 - 3w² + 3w) x (8w⁶)

(8w³ - 8 - 24w² + 24w )(8w⁶)

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷

Therefore, the expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

#SPJ5

Answer and explanation:

They are not equivalent because if we simplify the second expression, the result isn't the same:

7(y×b)+3b

= 7(yb)+3b

=7yb + 3b

Therefore 7yb+3b≠7y+7b+3y

And even though you meant

7(y+b)+3b

=7y+7b+3b

=7y+10b

7y+10b≠10y+7b

Hope his helps and have an amazing day *^____^*

Answer:

2

Step-by-step explanation:

If 1 box holds 7 books...

2 boxes hold 14 books.

3 boxes hold 21 books.

4 boxes hold 28 books.

5 boxes hold 35 books.

However, since there are only 30 books, the 5th box won't be completely filled up. This gives us the answer: If Lamont fills up each box he would have 30-28, or 2 books left over.

Its basically the same thing as 4 x 6 (which is 24) the only difference here is that the 4 is a negative.

POSITIVE FORM             NEGATIVE FORM

4 x 6 = 24                           -4 x 6 = -24

Answer:

280

Step-by-step explanation:

Through trial and error, one can figure out that the answer is 280. Now, you might first try to go 8 * 6 * 4, which equals 192. However, if you get the product of two negative numbers, it becomes a positive, which we can use. Using the numbers -7, -5 (which cancel out each other making the product positive), and 8, the product of all of them is 280. The largest product that Khushali can make is 280.

8 * 6 * 4 = 192

(-7) * (-5) * 8 = 35 * 8 = 280

The answer is C

Step-by-step explanation:

Exponential decay is when b is between 0 and 1.

Answer:

C. y = 10(0.13)^x.

Step-by-step explanation:

exponential decay is decreasing from what I remember from Algebra 1 Honors. So therefore, your only answer can be C. y = 10(0.13)^x.

The others all increase because 31, 3.1, 1.03 are all bigger than 1 which means that they increase while .13 decreases.

C. y = 10(0.13)^x.

Answer:

radius = 3

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here A = 9π , then

πr² = 9π ( divide both sides by π )

r² = 9 ( take the square root of both sides )

r = [tex]\sqrt{9}[/tex] = 3
