(g•h)=g(h(x))
So that means subbing h(x) into g(x) wherever there’s an “x”
So
= 3/ [h(x)-2]
= 3/(9x-2)
Then we sub in the 7
=3/ [9(7)-2]
=3/61
Answer:
4 1/2 divided by 3/4 = 6
Step-by-step explanation:
4 1/2 divided by 3/4
4 1/2 x 4/3 = 6
Answer:
139 ft
Step-by-step explanation:
So the zip line forms a right triangle. The height of the triangle is 150 ft, and the opposite angle is 40°. The horizontal distance covered by the zip liner can be found with trigonometry, specifically with tangent.
tan 40° = 150 / x
x = 150 / tan 40°
x ≈ 179 feet
But this includes the 40 ft long body of water, so the amount of ground covered is:
179 ft - 40 ft = 139 ft
Answer:
sqrt(sqrt(x))
Step-by-step explanation:
A quartic root of is written mathematically as . THe quartic root of 16 is 2 since 2*2*2*2 = 16. However, a quartic root can also be defined as the square root of a square root. For example the √16 = 4 and the √4 = 2. This is the same response as taking the quartic root. This means you can write it as the sqrt(sqrt(x)). In the example, it would be sqrt(sqrt(16)) = sqrt(4) = 2.
