Answer:
Each part is 3.5 inches long.
Step-by-step explanation:
The ruler has a length of 7-inches, so when you want to split it directly in half, you divide 7/2. This is the number 3.5 inches. On the ruler you can see when looking at the first segment that it goes from 0 inches to half-way between 3 inches and 4 inches, which is 3.5 inches.
The questions ask you to caculate how many elements must a set of numbers of proper subsets of the set 1/2 of the total number of subsets per a subset,base on the question I bet the answer is 1 I hope this helps let me know if u passed and I will try to work it out again GREAT LUCK!!
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would solve a similar question:
Find the distance between the two points shown on the coordinate plane. (Round your answer to the
nearest tenth.)
Solution:
The coordinate plane is a plane formed by the intersection of the vertical line and the horizontal line. The vertical line is known as the y axis and the horizontal line is the x axis. The y axis and x axis intersect at a point known as the origin.
The distance between two points
on the coordinate plane is given by:
![Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}](https://tex.z-dn.net/?f=Distance%3D%5Csqrt%7B%28y_2-y_1%29%5E2%2B%28x_2-x_1%29%5E2%7D)
Given points (-2, -1) and (2, 3), the distance is:
![Distance=\sqrt{(3-(-1))^2+(2-(-2))^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}](https://tex.z-dn.net/?f=Distance%3D%5Csqrt%7B%283-%28-1%29%29%5E2%2B%282-%28-2%29%29%5E2%7D%3D%5Csqrt%7B4%5E2%2B4%5E2%7D%3D%5Csqrt%7B16%2B16%7D%3D%5Csqrt%7B32%7D)
The value of h(3) is 120 ⇒ B
Step-by-step explanation:
To find the value of f(x) at x = a, do that
- Substitute x by a
- Find the value of f(a)
∵
- To find h(3) substitute x by 3
∴
∵
= 81
∵ (3)² = 9
- Substitute them in the function above
∴ h(3) = 2(81) - 4(9) - 2(3)
∴ h(3) = 162 - 36 - 6
∴ h(3) = 120
The value of h(3) is 120
