Answer:
B.18
Step-by-step explanation:
2+1+3
3+3=6
6+5=11
11+7=18
Answer:
s = 6, r = 8 or s = 4, r = 7
Step-by-step explanation:
2r - s = 10
2r = 10 + s
r = 5 + s/2 --(1)
rs - s^2 = 12 --(2)
sub (1) into (2):
(5 + s/2)s - s^2 = 12
5s + 0.5s^2 - s^2 = 12
-0.5s^2 + 5s - 12 = 0
s^2 - 10s + 24 = 0
(s - 6)(s - 4) = 0
therefore s = 6 or s = 4
when s = 6, r = 8 and when s = 4, r = 7
if you would like to discover more about simultaneous equations, you can have a look at my Instagram page (learntionary). I'll be posting mathematics related stuff there and some of my notes (simultaneous enq notes are already posted!)
A ball dropped from the top of the building can be modeled by the function f(t)=-16t^2 + 36 , where t represents time in seconds after the ball was dropped. A bee's flight can be modeled by the function, g(t)=3t+4, where t represents time in seconds after the bee starts the flight.
Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.
≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
