Answer:
The answer is 7.
Step-by-step explanation:The tenths place is the first number after the decimal. In order to know what happens to the whole number you look at the number after the decimal and if its greater than 5 then goes up if no it stays the same. Ex: 2.5 rounded to the tenths place is 3
For the first one its a slope of -2/3
The second one is 4/5
and the third one is -1/7
The Answer is: x1=-4 x2=1.
Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
Answer:
f(1) = 1
Step-by-step explanation:
The value of f(1) simply means what is the corresponding output we would get for an input of 1.
This also implies that for what of y is x equal to 1?
From the graph, when x = 1, y = 1.
Thus:
f(1) = 1
