The increase in the number of humans living on Earth (N, as measured in billions) with time t (as measured in years since 1800)

NemiM [27]

Answer:

The slope of the line would be 0.00910 in a logarithm graphic.

Step-by-step explanation:

Statement is incomplete. The correct sentences are: The increase in the number of humans living on Earth (N, as measured in billions) with time t (as measured in years since 1800) is modeld by the following function: N = 0.892e^0.00910t. If you were to graph in ln (N) versus t, what would be the slope of the line?

Let be $N(t) = 0.892\cdot e^{0.00910\cdot t}$ , where $N(t)$ is the number of humans living on Earth, measured in billions, and $t$ is the time, measured in years since 1800. As we notice, this is an exponential function and its slope is not constant and such expression have to be linearized by using a logartihm graphic. We add logarithms on each side of the formula and simplify the resulting expression by means of logarithmic properties:

$\log N(t) = \log \left(0.892\cdot e^{0.00910\cdot t}\right)$

$\log N(t) = \log 0.892 + 0.00910\cdot t$

In a nutshell, the slope of the line would be 0.00910 in a logarithm graphic.

Real populations sometimes increase beyond their environment’s carrying capacity in a relatively short period of time. What is t

Yanka [14]

Answer:

Overshoot.

Step-by-step explanation:

Let us know the meaning of given words.

Logistic growth occurs when population reaches carrying capacity of its environment. It does not surpass carrying capacity.

When population surpasses carrying capacity of its environment then a crash or a die-off happens, which causes a decline in population density. This crash or die off is known as collapse. The consequences of overshoot is known as collapse.

In population dynamics overshoot occurs when a population surpasses its carrying capacity. Overshoot is a temporary condition.

Therefore, from above explanation we can see that overshoot is the correct answer for the given phenomenon.

I need help with trigonometry Again..

tigry1 [53]

Answer: C. - √2

Step-by-step explanation:

Given requirements from the question

Find the exact value of sec 135°

Convert into common trigonometric expression

sec = secant

secx = 1 / cosx

Therefore, sec 135° = 1 / (cos 135°)

Find the reference angle

135° is quite a complicated angle, but it is possible to simplify it by finding its reference angle.

Since 135° is in the second quadrant, its reference angle will be

180° - 135° = 45°

However, we need to consider the positive and negative.

In a coordinate plane, the clue is (A S T C), which corresponds to the positive values in each quadrant. In the QI, "All" are positive. In the QII, sine is positive. In the QIII, the tangent is positive. In QIV, cosine is positive.

Therefore, when the value of cosine is in QII, it is negative.

The reference angle = - (1 / cos 45°)

Determine the final value

Given that the reference angle = - (1 / cos 45°)

cos 45° = 1 / √2

Therefore:

sec 135° = - (1 / cos 45°) = - (1 / (1 / √2)) = $\boxed{-\sqrt{2} }$

Hope this helps!! :)
