Neporo4naja [7]3 years ago
3 0

Answer:

Step-by-step explanation:

6x-10x^2+3-(5x^2+3x-4)

when there is a - in front of an expression in (), change the sign of each term in the expression

6x-10x^2+3-5x^2-3x+4

now collect like terms

3x-10x^2+3-5x^2+4

3x-15x^2+3+4

3x-15x^2+7

now use the commutative property to reorder the terms

-15x^2+3x+7

=-15x^2+3x+7

Sin^2A-cos^2B=sin2^B-cos^2A​
Rashid [163]

Answer:

see explanation

Step-by-step explanation:

Using the trig identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x

cos²x = 1 - sin²x

Consider the left side

sin²A - cos²B

= (1 - cos²A) - (1 - sin²B) ← distribute parenthesis

= 1 - cos²A - 1 + sin²B

= sin²B - cos²A

= right side , thus verified

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.
