Answer:
25/30
Step-by-step explanation:
because 3 multiplies into 30, 10 times and 2 multiplies into 30, 15 times so you add 10+15 to get 25
-13v=195
divided each side by -13: v = -15
Answer:
If x = time in seconds, the answer is 1 second.
Step-by-step explanation:
The question is asking for the maximum height and the time it was achieved, so in terms of a graph, it is the vertex coordinates. Luckily this equation is in vertex form, so it gives us those points. The -1 in the equation is the x, but you invert this sign, because even thought the value on the graph is positive, it tells you to subtract 1, therefore adding -1, so for this part (the x part of the equation) remember to invert the sign.
The other part (the height) comes from the equation adding 45 at the end. This is the highest y point, and therefore the answer is (1,45), 1 second for 45 meters high.
17 because 4x3 is 12 +5 is 17 unless I'm stupid and idk how to do that ;D
Answer:
t =
Step-by-step explanation:
since t varies inversely with v then the equation relating them is
t = ← k is the constant of variation
to find k use the given condition n = 7, t = 1.5 then
k = vt = 7 × 1.5 = 10.5
t = ← is the equation
