What is the coefficient of x² in 3x² 5 )( 4 4x²?

Answer:

1). y = 4(1.75)ˣ

2). y = (2)ˣ

Step-by-step explanation:

1). Let the equation of the given exponential graph is,

y = a(b)ˣ

Graph of the given equation passes through two points (0, 4) and (0+1, 4+3)

For point (0, 4),

4 = a(b)⁰

a = 4

For point (1, 7),

7 = 4(b)¹

b = [tex]\frac{7}{4}[/tex]

b = 1.75

Therefore, equation of the function is,

y = 4(1.75)ˣ

2). Similarly, equation of the second graph will be same in the form of

y = a(b)ˣ

Second graph passes through the points (0, 1) and (2, 4)

For (0, 1),

1 = a(b)⁰

a = 1

For (2, 4),

4 = 1(b)²

b = 2

Therefore, exponential function representing the graph will be,

y = 1(2)ˣ

y = 2ˣ

Answer:

2.504 feet

Step-by-step explanation:

Find the length by dividing 10.016 by 4

10.016/4

= 2.504

So, each cut board will be 2.504 feet

We have

[tex] \begin{cases} \sf No. \: of \: pieces = \frak{4} \\ \sf Total \: Length = \frak{10.016 \: ft} \end{cases} [/tex]

So,

Length of 1 board = 10.016/4

Length of 1 board = 2.504 ft

So,

The length of 1 board is 2.504 ft.

Answer:

Associative property of addition

Step-by-step explanation:

The associative property of addition is as follows :

a+(b+c) = (a+b)+c

We have,

a = 8, b = 9 and c = 3

So,

Using above property,

(8+9)+3 = 8+(9+3)

20 = 20

Hence, this is the required solution.

Answer: 18 ft

Step-by-step explanation:

Given

Scale is 1inch:9 feet

1 feet= 12 inch

The dividing board is 2 inches long

Suppose the actual length of the diving board is x

[tex]\therefore \dfrac{1}{9\times 12}=\dfrac{2}{x}\\\\\Rightarrow x=\dfrac{9\times 12\times 2}{1}\\\\\Rightarrow x=216\ inch\ \text{or}\ 18\ ft[/tex]

Answer:

[tex]slope = 1 [/tex]

Step-by-step explanation:

We can see that the graph cuts the x axis at , (-1,0) and y axis at (0,1) . So we can find the slope as ,

[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{ 1-0}{0+1} \\\\\implies\boxed{\boxed{ slope = 1 }}[/tex]

Answer: y=30x

top soil is 5 more dollars than mulch

Step-by-step explanation:

to find y=30x

see what y equals when x equals 1

The cost of the topsoil is $5 more than the cost of the mulch.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, the equation, y=25x, represents the cost, y, in dollars, of x cubic yards of mulch at the garden shop.

From the, graph we have coordinates (1, 30) and (2, 60)

We know that, slope of points is (y2-y1)/(x2-x1)

Now, (60-30)/(2-1)

= 30

Substitute, m=30 and (x,y)=(1, 30) in y=mx+c, we get

30=30(1)+c

c=0

Substitute, m=30 and c=0 in y=mx+c, we get

y=30x

Per 1 cubic yard

Topsoil is y=30x=$30 and cost of the mulch is y=25x=$25

So, difference in cost is 30-25=5

Comparing cost in both the situation, the cost of the mulch is less than topsoil

Therefore, the cost of the topsoil is $5 more than the cost of the mulch.

Step-by-step explanation:

b = 106, solve 106 - 24 and you get 82.

Hope this helped.

Answer:

b/24=82

Step-by-step explanation:

Since the difference of an equation is the outcome of division we place 82 as the answer.  

Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.

Answer:

270 cm3

Step-by-step explanation:

The volume of the given rectangular prism is 270 cm³.

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.

We have

Length = 9 cm

Width = 2 cm

Height = 15 cm

Using the formula for volume of the rectangular prism

= length x width x height

= 9 x 2 x 15

= 270 cm³

Thus, the volume of the given rectangular prism is 270 cm³.
