Answer:
Step-by-step explanation:
The question is faulty. It works once it gets to + 1, +2, +3
The other x values should be 0 and - 1 instead of -1 and -3.
Here's the formula I get.
f(x) = 2*3^(2x + 1)
f(0) = 2*3^(1)
f(0)= 6
f(-1) = 2*3^(-2 + 1)
f(-1) = 2*3^(-1)
f(-1) = 2/3
f(-2) = 2*3^(-2*2 + 1)
f(-2) = 2*3^(-4 +1)
f(-2) = 2*3^(-3)
f(-2) = 2/27
Since my answers do not agree with the given answers, I can do nothing more to help you. I will pass this along to someone I know who will see through it.
Answer:
-0.69 feet per second
Step-by-step explanation:
We have dx/dt = 2 ft/sec, and we want to determine dy/dt.
x and y are related by the Pythagorean Theorem.
x²+y²=16²
Differentiate both sides of this equation with respect to t to get
Divide both sides by 2y
When x = 5 ft, we have
x²+y²=16²
5²+y²=256
y²=256-25=231
therefore
y= 
=-0.69
The top of the ladder is sliding down (because of the negative sign in the result) at a rate of -0.69 feet per second.
Answer:
The answer is A
Step-by-step explanation:
We need to multiply 1876 by 12. 1876 * 12 = 22, 512. That's our answer
Well, it's the product of 8/9 and the 4 miles. The result is 32/9 miles, that is, 3,55 miles.
Answer:
multiply the scale drawings side lengths by the scale
Step-by-step explanation:
for instance, if i have a square shaped scale drawing with the side lengths of 4in, and the scale is 2in, i would multiply 4 by 2, and the actual drawing's side lengths would be 6.
if i did not know the scale and i knew the actual drawings side lengths and the scale drawings side lengths, i would divide the corresponding lengths
example: rectangular scale drawing with the lengths, 5, 5, 10, and 10. and an actual drawing with the lengths 10, 10, 20, and 20. if i divide 20 by 10 or 10 by 5, i'd get 2, the scale
