![b - 27 > 3 \\ b > 3 + 27 \\ b > 30](https://tex.z-dn.net/?f=b%20-%2027%20%3E%203%20%5C%5C%20b%20%3E%203%20%2B%2027%20%5C%5C%20b%20%3E%2030)
Group 1 elements are comprised of: (1) hydrogen, sodium, lithium, potassium, rubidium, caesium, and francium. The tendency of these atoms is to lose one of their electrons such that they become charge +1.
Group 5 elements contains the vanadium, niobium, tantalum, and dubnium. It is quite hard to predict the oxidation number of these elements such that it will be hard to determine the number of atoms needed to react with them. Their valence electron is 5, and they react by losing them. Hence, in order to reach the octet rule, 3 group 1 elements should be reacted.
Answer:
Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle. So, ABCD is a cyclic Quadrilateral.
Opposite angles of cyclic quadrilateral are supplementary.
Therefore,
![m\angle A + m\angle C = 180\degree \\ (14z - 7) \degree + (8z) \degree = 180 \degree \\ (14z - 7 + 8z) \degree= 180 \degree \\ (22z - 7) \degree= 180 \degree \\ 22z - 7 = 180 \\ 22z= 187 \\ z = \frac{187}{22} \\ z = 8.5 \\ \\ m\angle A = (14z - 7) \degree \\ = (14 \times 8.5 - 7) \degree \\ = (119 - 7) \degree \\ m\angle A = 112 \degree \\ \\ m\angle C =180 \degree - 112 \degree \\ m\angle C =68 \degree \\ \\ m \angle D = (10 \times 8.5) \degree \\ m \angle D = 85 \degree \\ \\ m\angle B =180 \degree - 85 \degree \\ m\angle B=95 \degree](https://tex.z-dn.net/?f=m%5Cangle%20A%20%2B%20m%5Cangle%20C%20%3D%20180%5Cdegree%20%20%5C%5C%20%2814z%20-%207%29%20%5Cdegree%20%2B%20%288z%29%20%5Cdegree%20%3D%20180%20%5Cdegree%20%5C%5C%20%2814z%20-%207%20%2B%208z%29%20%5Cdegree%3D%20180%20%5Cdegree%20%5C%5C%20%2822z%20-%207%29%20%5Cdegree%3D%20180%20%5Cdegree%20%5C%5C%2022z%20-%207%20%3D%20180%20%20%5C%5C%2022z%3D%20187%20%5C%5C%20z%20%3D%20%20%5Cfrac%7B187%7D%7B22%7D%20%20%5C%5C%20z%20%3D%208.5%20%5C%5C%20%20%5C%5C%20m%5Cangle%20A%20%20%3D%20%2814z%20-%207%29%20%5Cdegree%20%5C%5C%20%20%3D%20%20%2814%20%5Ctimes%208.5%20-%207%29%20%5Cdegree%20%5C%5C%20%20%3D%20%28119%20-%207%29%20%5Cdegree%20%5C%5C%20%20m%5Cangle%20A%20%3D%20112%20%5Cdegree%20%5C%5C%20%20%5C%5C%20m%5Cangle%20C%20%3D180%20%5Cdegree%20%20-%20112%20%5Cdegree%20%5C%5C%20m%5Cangle%20C%20%3D68%20%5Cdegree%20%5C%5C%20%20%5C%5C%20m%20%5Cangle%20D%20%3D%20%2810%20%5Ctimes%208.5%29%20%5Cdegree%20%20%5C%5C%20m%20%5Cangle%20D%20%3D%20%2085%20%5Cdegree%20%20%5C%5C%20%20%5C%5C%20m%5Cangle%20B%20%3D180%20%5Cdegree%20%20-%2085%20%5Cdegree%20%5C%5C%20m%5Cangle%20%20B%3D95%20%5Cdegree%20)
Step-by-step explanation:
The horizontal stretch or compression for a function f(x) is given by g = f(bx) where b is a constant. If b> 0 then the graph of a function is compressed.
As it is given in the question that the function is transformed by a compression factor of 3.
Given function
The value of k will be 3 if the function is transformed by a compression factor of 3
