Step-by-step explanation:

If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.

If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

Answer:

92,000i think this is the answer

Answer:

the first term is a1

the 8th term is a8

the 4th term is a4

we have:

[tex]a8=a1.3^{7}\\\\<=>4374=a1.3^{7}\\\\<=>a1=2[/tex]

with a1 = 0,002 => a4 = a1.3³ = 2.27 =54

Step-by-step explanation:

The 4th term of the given geometric sequence is 54.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

The nth term of a GP is given as a[tex]r^{n-1}[/tex]

As per the given,

Common ratio r = 3

8th term = 4374

a(3)⁸⁻¹ = 4374

a = 2

The 4th term will be as, 2 x (3)⁴⁻¹ = 54

Hence "The 4th term of the given geometric sequence is 54".

Answer:

143 acres.

Step-by-step explanation:

To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.

To find a percent of a number, multiply the percent by the number.

0.2% is equal to 0.002.

73,000 x 0.002 = 143

So, 143 acres of the forest is old-growth trees.

Answer:

480mm<55cm<0.5m

Step-by-step explanation:

millimeters means 100

centimeters means 10

meters means 1

there are 10mm in every 1cm and 100cm in every 1m

Answer:

55cm>0.5m>480mm

Step-by-step explanation:

as we know

1000mm=1m

100cm=1m

So we see

55=55cm

0.50=50cm

480=48cm

Answer:a

Step-by-step explanation:

Bsnanna

If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2

Option D is the correct choice

The points that lie on the line k are:

(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).

We can find the slope of the line k by picking any two points on the line

The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

On the line k, let us select the points (1,3) and (2, 1)

x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1

[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]

Therefore, the slope of the line k is -2

Answer:

16 mg

Step-by-step explanation:

[tex]N_0[/tex] = Initial mass of sample = 540 mg

t = Time taken = 2 years

[tex]t_{1/2}[/tex] = Half life of isotope

N = Final mass of sample = 300 mg

Radioactive decay is given by

[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow \ln\dfrac{N}{N_0}=-\dfrac{\ln 2}{t_{1/2}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{N}{N_0}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{300}{540}}2\\\Rightarrow t_{1/2}=2.358\ \text{years}[/tex]

In 2021 the number of years passed from 2009 would be 12 years

[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=540e^{-\dfrac{\ln 2}{2.358}12}\\\Rightarrow N=15.86\approx 16\ \text{mg}[/tex]

The expected mass of the sample in the year 2021 would be 16 mg.
