Answer:
a. 36 b. 217.1
Step-by-step explanation:
l x w= 6 x 6 = 36
14x21=294
Area of a circle = pi r squared
7x7=49
49/2=24.5
24.5 x 3.14=76.93
294-76.9=217.1
Answer:
Year 2034
Step-by-step explanation:
In 2000, 64% had one or more pets
<em>Since decreasing at 1% per year, we can say:</em>
<em>In 2001, 63%</em>
<em>In 2002, 62%</em>
<em>In 2003, 61%</em>
<em>In 2004, 60%</em>
<em>And so on</em>
<em />
To go to 30% from 60% in 2004, we would need to decrease 60 - 30 = 30%, and that will occur after 30 more years. So that would be the year
2004 + 30 = 2034
So, year 2034
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.
