According to the order of operations, exponents must be evaluated before multiplication.
Here's and example where x=2.
7*3^2
7*9
63
21^2=441
63 does not equal 441
Answer:
200 m
Step-by-step explanation:
Answer: a) 7
b) c
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped.
a)
f(7) = 22 means ..... when x = 7, then y = 22
The inverse is ..... when x = 22, then y = 7
b)
f⁻¹(f(c)) means ...... when x = f(c), then y = c
The reverse of the inverse is ..... when x = c, then y = f(c)
Answer:
B. <2,-5>
Step-by-step explanation:
We are given the vectors,
u = <-2,0> and v = <4,-5>
It is required to find the sum of the vectors i.e. u + v.
So, we have,
u + v = <-2,0> + <4,-5>
i.e. u + v = < -2+4 , 0-5 >
i.e. u + v = <2,-5>
Thus, the sum of the vectors written as ordered pairs is <2,-5>.
Hence, option B is correct.
