Answer:
y= tan (x+pi/2) is the answer
Let d be distance travelled when they are level , and t = time that nora took to get level with mason
for Nora
6 = d/t
d = 6t
for Mason
5 = d / (t + 35)
d = 5 ( t + 350
so 6t = 5(t + 35)
solve for t
The ordered pairs are:
<span>{(1, 80), (2, 240), (3, 720), (4, 2160)}
with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160
The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3
The equation is:
a_n = 80 * 3^(n - 1)</span>
Answer : 137.25
Step 1 - Convert the base of a triangle to decimal form
15 1/4 = 15.25
Step 2 - Multiply base by height
18 * 15.25 = 274.5
Step 3 - Divide 274.5 by 2
274.5 ÷ 2 = 137.25
