Answer:
Option C is correct i.e. 2.
Step-by-step explanation:
Given the function is f(x) = x² +8x -2.
We can compare it with general quadratic expression i.e. ax² +bx +c.
Then a = 1, b = 8, c = -2.
We can find the number of real root by finding discriminant of the equation ax² +bx +c =0 as follows:-
D = b² -4ac
D = 8² -4*1*-2
D = 64 +8
D = 72.
When D is a positive value, then we have two real roots of the equation.
Hence, option C is correct i.e. 2.
Answer:
8/100 is equivalent to 0.08
Step-by-step explanation:
The second digit place to the right of the decimal point is the hundredths place, so that is where the 8 belongs because it is 8/100 in fraction form.
Hope this helped :)
Answer:
g(1) = 0
There is a remainder of 10 so you can automatically cross out 3 and 4.
-136 = 8m - 8
-136 + 8 = 8m
-128/8 = m
-16 = m
M = -16
Answer:
⅗
Step-by-step explanation:
12÷20 = ⅗
since the ratio is proportional
there for the ratio is still ⅗
