Step-by-step explanation:
1) P = 47,100 + 2,550t
Given P = 95000
So,
95000 = 47100 + 2550t
Subtract 47100 from both sides,
95000 - 47100 = 2550t
47900 = 2550t
Divide by 2550,
t = 47900/2550 = 18.78 = 18.8 years
2) Given P = 43,100 + 3,150t
Both P must be equal.
47100+2550t = 43100+3150t
Subtract 43100 and 2550t from sides,
47100- 43100 = 3150t - 2550t
4000 = 600t
Divide by 600,
t = 4000/600 = 6.67 = 6.7 years
Answer:
Exponential growth
Step-by-step explanation:
Malthus published a book in 1798 stating that populations with unlimited natural resources grow very rapidly, after which population growth decreases as resources become depleted. This accelerating pattern of increasing population size is called exponential growth.
Answer:
The answer is 1st point.
Step-by-step explanation:
By following the steps that is shown in the picture :
56x² - 8x - 7x + 1
1.Group pairs of terms with common factor,
(56x² - 8x) + (-7x + 1)
2.Factor the GCF from each group,
8x(7x - 1) - 1(7x - 1)
3.Use distributive property,
(8x - 1)(7x - 1)
Y can realistically be any positive number, since a negative number multiplied by a positive number's product is negative. a negative number will always be less than a positive number, in this case the positive number being 60.
<span>a negative number multiplied by another negative number's product is positive, so as long as the negative numbers are less than -6 (because -10 times -6 is 60, and 60 is not less than 60) y can be negative.</span>

Step-by-step explanation:
5x-17 and 3x-11 are supplementary angles
They add up to 180 degrees
5x-17 + 3x - 11 = 180
8x - 28 = 180
8x= 208
x= 26
3x-11, 90, and 2y + 5 added together equal 180
3x-11 + 90 + 2y + 5 = 180
3(26) - 11 + 2y + 5 = 90
78 - 6 + 2y = 90
72 + 2y = 90
2y = 18
y = 9
I hope this helps!!!
