I can't really explain how but hopeful this help
L=6 cubes
w=3 cubes
h=4 cubes
v=lwh
= (6)(3)(4)
= 72 cubes
Answer:
7.28 miles
Step-by-step explanation:
Suppose the distance at closest approach is represented by x. Then the distance to the point of closest approach at the first sighting is ...
d1 = x·tan(62°)
At the second sighting, the distance to the point of closest approach is ...
d2 = x·tan(38°)
The difference of these distances is 8 miles, so we have ...
d1 -d2 = 8 = x(tan(62°) -tan(38°))
Dividing by the coefficient of x, we find ...
x = 8/(tan(62°) -tan(38°)) ≈ 7.2764 . . . . miles
The point of closest approach is about 7.28 miles from the landmark.
If you meant to write ax^n, then yes this is a polynomial as long as n is a positive whole number.
Something like 2x^3 is a polynomial but other things like 7x^(1.5) or 3x^(-5) are not polynomials.
The value of 'a' does not determine if ax^n is a polynomial or not.
Answer:
100 girls
Step-by-step explanation:
The ratio of boys : girls is 2 : 5.
In other words, boys are 2 parts of the school while girls are 5 parts of the school.
Since there are 40 boys, 2 parts of the school is 40. Thus:
1 part is 20.
Since there are 5 parts girls, there are
100 girls.
Answer: 100 girls
