Ann went (1) for his distance
Answer:
12
Step-by-step explanation:
I think you have to use the product rule for counting- which is where you multiply the two numbers. I'm not sure if this is right but I hope I helped
For this case what we must do is a composition of functions which will be given by:
m (x) = 4x - 11
n (x) = x - 10
We have then:
m [n (x)] = 4 (x - 10) - 11
Rewriting the function:
m [n (x)] = 4x - 40 - 11
m [n (x)] = 4x - 51
Answer:
a. m [n (x)] = 4x - 51
In this case it is to find the roots of the polynomial.
We have then:
2x ^ 2-5x + 1 = 3
Rewriting:
2x ^ 2-5x-2 = 0
Applying resolver we have
x = (- b +/- root (b ^ 2 - 4ac)) / (2a)
Substituting values:
x = (- (- 5) +/- root ((- 5) ^ 2 - 4 (2) (- 2))) / (2 (2))
x = (- (- 5) +/- root ((25 + 16)) / (2 (2))
x = (5 +/- root (41))) / (4)
x = ((5/4) +/- (root (41)) / 4)
Answer:
x = ((5/4) +/- (root (41)) / 4)
(option 4)
Answer:
19,200 cm^2.
Step-by-step explanation:
The area = 1.2 * 1.6 = 1.92 m^2.
There are 100 cm to 1 meter, so 1 square meter = 100^2 = 10,000 cm^2.
Therefore 1.92 m^2 = 10,000 * 1.92 = 19,200 cm^2.
