AFD = 49
49 + 58 = 108
DAF = 180 - 108 = 72
BFD = 180 - 49 = 131
131 + 20 = 151
BAF = 180 - 151 = 29
DAB = 29 + 72 = 101
DAB = 101
Answer:
14.3 km (1 d.p.)
Step-by-step explanation:
To find the <u>mean</u>, divide the sum of all data values by the total number of data values.
If Mark ran a mean distance of 13.2 km in five days, we can use the mean distance for each of the 5 days in our calculation.

Answer:
y - 2 =
(x + 8)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m =
and (a, b) = (- 8, 2), hence
y - 2 =
(x + 8) ← in point- slope form
Answer:
f(-2) = -6
Step-by-step explanation:
In the expression, to get f(-2);
we simply substitute the value of x with -2
We have this as;
f(-2) = -4(-2)^2 + 10
f(-2) = -4(4) + 10
f(-2) = -16 + 10
f(-2) = -6
