Answer:
Step-by-step explanation:
"100" or any constant at the end of the equation is r² (radius squared). So, the radius is 10.
the center of the circle is (-6, 2)
the equation template of a circle is (x -h)² + (y - k)² = c
(h,k) is the center of the cirlce.
Answer:
4 (100-250 words with a 100-word minimum)
There are many ways you can say it,
one of them would be:
8 added to 5 multiplied by x
Answer:
6
Step-by-step explanation:
To divide a fraction by a fraction, you turn one of them upside down and multiply:
(6/2) / (3/4) = (6/2) x (4/3)
Multiply the fractions by multiplying the top by the top and the bottom by the bottom:
(6/2) x (4/3) = (6x4)/(2x3) = 24/6
24/6 can be simplified to 4.
Answer:
f(4) = -15
Step-by-step explanation:
Since we have an average rate of change, we can deduce that a line, with a gradient of -6 joins the points on the function, f, when the parameter is 1 and when it is 4, i.e. the line passes through the point (1, 3) and has a gradient of -6;
From this, we know that for every value of x we increase the, value y will decrease by 6;
So if we increase 1 by 3, to get to 4, the y value must decrease by 18 (3×6);
Written mathematically, it would look like:
f(4) = 3 + (4 - 1)(-6)
= 3 - 18
= -15
(4, -15)
