Answer:

The domain of the relation is 0 ≤ x ≤ 4

The range of the relation is all real numbers  (-∞, ∞)

Step-by-step explanation:

Domain : the set of possible x-values (the "input" values)

Range : the set of y-values (the "output" values)

The domain of the relation is 0 ≤ x ≤ 4

The range of the relation is all real numbers (-∞, ∞)

Answer:

9/2

Step-by-step explanation:

Direct variation is

y = kx where k is the constant of variation

Substitute into the equation to find k

y=3 and x=2

3 = k*2

Solve for k

3/2 = k

y = 3/2 x

We know x =3

y = 3/2 * 3

y = 9/2

Answer:

A

Step-by-step explanation:

given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 3 when x = 2 , then

3 = 2x ( divide both sides by 2 )

[tex]\frac{3}{2}[/tex] = k

y = [tex]\frac{3}{2}[/tex] x ← equation of variation

When x = 3 , then

y = [tex]\frac{3}{2}[/tex] × 3 = [tex]\frac{9}{2}[/tex] → A

The farmer has a very insufficient way of farming he is a fake farmer if he only plants 3 crops a row and than 12 in the next he most likely has no pattern but if we do trigonometrically mitochondria math we can figure out that his patter does exist but only to him. since the farmer goes but he goes up by four cuz 3 x 4 is a number 12 and than 12 x 4 is 48 which the farmers produce will all die on his crusty land.  

Answer:

[tex]2x^2(1-10x^3)[/tex]

Step-by-step explanation:

Factor  [tex]2x^2-20x^5[/tex]

Apply the exponent rule:  [tex]a^{b+c}=a^ba^c[/tex]

[tex]\implies 2x^2-20x^2x^3[/tex]

Rewrite 2 as 2 · 1 and 20 as 2 · 10:

[tex]\implies 2 \cdot 1x^2-2 \cdot 10x^2x^3[/tex]

Factor out common term [tex]2x^2[/tex]:

[tex]\implies 2x^2(1-10x^3)[/tex]

Using improper fractions, it is found that the percent of increase in the temperature of the solution was of 76.08%.

The conversion is made according to the following formula:

[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]

In this problem, the initial temperature was given by:

[tex]9\frac{4}{5} = 9 + \frac{4}{5} = 9.8[/tex]

The final temperature was given by:

[tex]17\frac{1}{4} = 17 + \frac{1}{4} = 17.25[/tex]

The percent change is given by the change divided by the initial temperature, and multiplied by 100%. Hence:

[tex]C = \frac{17.25 - 9.8}{9.8} \times 100\% = 76.02\%[/tex]

Step-by-step explanation:

Answer:

Given :

The diagonal of a rectangle is 2 ✓13 cm.

The length and breadth are in the ratio

3:2.

To find :

The Area of the rectangle.

Solution :

Given that

The ratio of the length and breadth of a rectangle = 3:2

Let they be 3X cm and 2X cm

We know that

The diagonal of a rectangle = √(1²+b³)

units

The diagonal of the rectangle

= √[(3X)³+(2X)³] cm

= √(9x³+4x²) cm

=> √(13X²) cm

=> √13 X cm

According to the given problem

The diagonal of the rectangle = 2√13 cm

=> ✓13 X = 2 √13

=> X = 2√13/√13

=> X = 2 cm

If X = 2 cm then 3X=3(2) = 6 cm

If X = 2 cm then 2X = 2(2)=4 cm

Length = 6 cm

Breadth = 4 cm

We know that

Area of a rectangle = length breadth sq.units

Area of the given rectangle = 6 cm x 4 cm

= 24 cm²

Answer:

Solution:

(0.2)x = 2.

Taking log on both sides

log (0.2)x = log 2.

x log (0.2) = 0.3010, [since log 2 = 0.3010].

x log (2/10) = 0.3010.

x [log 2 - log 10] = 0.3010.

x [log 2 - 1] = 0.3010,[since log 10=1].

x [0.3010 -1] = 0.3010, [since log 2 = 0.3010].

x[-0.699] = 0.3010.

x = 0.3010/-0.699.

x = -0.4306….

x = -0.4 (nearest tenth)

Answer is option (c) -0.4

The value of x to the nearest tenth is -0.4

Given the following expressions

(0.2)x = 2 and log 2 = 0.3010

Taking log of both sides of (0.2)x = 2

log (0.2)x = log 2.

x log (0.2) = 0.3010,

x [log 2 - log 10] = 0.3010.

Note that log2 2 = 1

x [log 2 - 1] = 0.3010

x [0.3010 -1] = 0.3010, [since log 2 = 0.3010].

x[-0.699] = 0.3010.

x = 0.3010/-0.699.

x = -0.4306

Hence the value of x to the nearest tenth is -0.4
