PART A
alligators:
x = total number of alligators
n = number of years
x=20*1.25^n
crocodiles:
y = total number of crocodiles
n = number of years
y=25+10n
PART B
alligators
x=20*1.25^4 = 48.82 round up to 49
crocodiles 25 +10(2) = 25+20 = 45
Part C
7 years
20(1.25^n)=25+10n
1.25^n=1.25+0.5n
n=7
check:
alligators 20+1.25^7 = 95.36
crocodiles = 25+10(7) = 95
Answer:
D. 54m
Step-by-step explanation:
by the side you can see that it is a right triangle with hypotenuse = 15
1/2(b)(h) = 1/2(9)(12) = 54
Answer:
√1780, or around 42.19005
Step-by-step explanation: pythagorean theorem: a^2+b^2=c^2
<u>Answer-</u>
<em>The radius is increasing at a rate of </em>
<u>Solution-</u>
The rate of change of the area of the crater is , i.e
We know that,
Putting this,
Applying chain rule,
Putting the value of radius as 4 (given),
Answer:
The axis of symmetry is -b/2a
The x-intercept shown is 3 units away from the axis of symmetry.
The other x-intercept also must be 3 units away from the axis of symmetry but on the opposite side.
Subtract 3 from the axis of symmetry.
The other x-intercept is (-b/2a-3,0)
Step-by-step explanation:
