Answer:

The bigger the population growth there are, the more the resource use increases

Step-by-step explanation:

Answer:

They both need equal attention because it could change rapidly. This also means the relationship between resource availability and population growth is that they both need space and population growth the population is gonna get to large and for resource availability, you want resources so you are resourceful. Therefore, an increase in human population growth means there is an increased need for natural resources to supply the basic needs of the population.

(x + 4) / (3x) - 5 / (2x)

= 2 (x + 4) / (6x) - 15 / (6x)   ………   multiply the first fraction by 3/3 and the second by 2/2 to get a 6 in both denominators

= (2 (x + 4) - 15) / (6x)   ………   combine the fractions

= (2x - 7) / (6x)   ………   simplify the numerator

so a = 2, b = -7, and c = 6.

203.20 millimeters

Step-by-step explanation:

StartFraction 8 inches Over question mark millimeters EndFraction = StartFraction 40 inches Over 1,016 millimeters

8 inches / ? Millimeters = 40 inches / 1,016 millimeters

8 × 1,016 = ? × 40

8,128 = 40?

Divide both sides by 40

? = 8,128 / 40

Answer:

solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]

First we will solve the inequality to find value of x

Solving:

[tex]\frac{7x-3}{9}\geq 8-2x[/tex]

Step 1: Multiply both sides by 9

[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]

Step 2: Adding 3 on both sides

[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]

Step 3: Add 18x on both sides

[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]

Step 4: Divide both sides by 25

[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]

So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Answer:

No

Step-by-step explanation:

For a point to be the midpoint of a line segment, it must bisect it into two equal segments and be on the line segment (hence, colinear with the endpoints). All four B points are equidistant from points A and C, but aren’t colinear with A and C. Therefore, they aren’t all midpoints of line segment AC.

Answer: 14 inches

Step-by-step explanation:

If one is 4 times the length of the other, then you'll have to divide by 5 because that's how many times there are in total. So 70/5 would be 14 which is the length of the smaller one. 70-14= 56 which is the length of the normal one.

The relation between wavelength and period of a wave is explained in the solution.

Wavelength is a characteristic of a wave that measures the distance between two points or particles that have the same phase of oscillation.

The relation between wavelength and period of a wave :-

In one period of a wave, one full cycle (peak through valley

and back to peak) passes by.

That means that the wave has moved by one wavelength.

Since speed is distance traveled / time spent, and a wave

moves a distance of one wavelength in a time of one

period, its speed must be:

speed = distance / time = wavelength / period

v = λ / p

We more often use frequency = 1 / period. Then:

speed = wavelength x frequency

v = λ x f

Answer:

The value of x at this instant is 3.

Step-by-step explanation:

Let [tex]x\cdot y = 18[/tex], we get an additional equation by implicit differentiation:

[tex]x\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (1)

From the first equation we find that:

[tex]x = \frac{18}{y}[/tex] (2)

By applying (2) in (1), we get the resulting expression:

[tex]\frac{18}{y}\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (3)

[tex]y\cdot \frac{dx}{dt}=-\frac{18}{y}\cdot \frac{dy}{dt}[/tex]

[tex]\frac{dx}{dt} = -\frac{18}{y^{2}} \cdot \frac{dy}{dt}[/tex]

If we know that [tex]y = 6[/tex] and [tex]\frac{dy}{dt} = 8[/tex], then the first derivative of x in time is:

[tex]\frac{dx}{dt} = -\frac{18}{6^{2}} \cdot (8)[/tex]

[tex]\frac{dx}{dt} = -4[/tex]

From (1) we determine the value of x at this instant:

[tex]x\cdot \frac{dy}{dt} = -y\cdot \frac{dx}{dt}[/tex]

[tex]x = -y\cdot \left(\frac{\frac{dx}{dt} }{\frac{dy}{dt} } \right)[/tex]

[tex]x = -6\cdot \left(\frac{-4}{8} \right)[/tex]

[tex]x = 3[/tex]

The value of x at this instant is 3.

The value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].

Differentiating the given equation  [tex]xy=18[/tex] with respect to the [tex]'t'[/tex] to get an addition equation by  implicit differentiation,

[tex]x\dfrac{dy}{dt}+y\dfrac{dx}{dt}=0----(i)[/tex]

Also, from the given equation, we can write [tex]x=\dfrac{18}{y}[/tex]

Substitute the value of [tex]x[/tex] in the equation (i), we get

[tex]\begin{aligned}\dfrac{18}{y}\dfrac{dy}{dt}+y\dfrac{dx}{dt}&=0\\\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\end{aligned}[/tex]

Substitute the value of [tex]y=6[/tex] and [tex]\dfrac{dy}{dt}=8[/tex] in the above equation, we get

[tex]\begin{aligned}\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\\&=\dfrac{-18}{6^2}\times 8\\&=-4\end{aligned}[/tex]

Now, from equation (i), we can re-write the expression to evaluate the value of [tex]x[/tex] at that instant as-

[tex]x=-y\dfrac{\frac{dx}{dt}}{\frac{dy}{dt}}\\x=-6(\dfrac{-4}{8})\\x=3[/tex]

Hence, the value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].

Answer:

578

Step-by-step explanation:

118

+560

answer:678

678-100=578

The sum of 118 and 560 is the same as adding 100 to 578.

To find the sum of 118 and 560, we can add the hundreds, tens, and ones separately.

Starting with the ones, 8 + 0 = 8.

Then, moving on to the tens, 1 + 6 = 7.

Finally, adding the hundreds, 1 + 5 = 6. Combining these results, we get 678 as the sum.

However, if we add 100 to 578, we get 678, which is the same as the previous result. This happens because when we add 100 to the sum of 118 and 560, we essentially increase the hundreds place by 1 while keeping the tens and ones the same.

The final answer is 578.
