Answer:
x^7-14x^6+84x^5-280x^4+560x^3-672x^2+448x^2-128
Step-by-step explanation:
ends are x^7 and 120^7, and use the therom in the middle
For this case we have the following equation:
From here, we must clear the value of y.
For this, we follow the following steps:
1) Distributive property:
2) Variable terms on one side of the equation and constant terms on the other side of the equation:
3) Algebraically add the constant terms:
4) Pass the number 20 to divide:
Answer:
The value of y is given by:
Answer:
We conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.
Step-by-step explanation:
We know that A function is a certain relationship is defined as having only one corresponding y-value for each x-value.
Considering the function
Here,
- x is the input and f(x) or y is the output.
- 'x' is often called an independent value and y is called the 'dependent' value.
Considering the table
x y
1 2
2 3
3 4
4 5
The values in the table satisfy the function y = x+1.
It is clear from the table that the function has only one corresponding y-value for each x-value. In other words, there is no repetition of 'x' value.
Therefore, we conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.
Given the sides 11,13,19, to calculate for the smallest angle using cosine rule, i.e;
a^2=b^2+c^2-2bc cos (A)
we shall proceed as follows;
The smallest angle is always opposite to the shortest side; Since 11 is our shortest side, the smallest angle is the angle opposite to this side. Thus;
let a=11 and our smallest angle be A
thus
11^2=13^2+19^2-2*13*19 Cos A
121=169+361-494 Cos A
121=530-494 Cos A
-409=-494 Cos A
dividing through by -494 we get;
Cos A=0.8279
thus
A=Cos(-1) 0.8279
A=34.113°≈34°
The answer is A=34°
