Answer:
(x+8)(x+5)
Step-by-step explanation:
Since we know x2 is equivalent to x times x we can automatically start by filling in the first two spaces with x. Then since we know that we're going to need two numbers that equal forty since it's part of the equation we can get two number that will also add up to 13x which is 8 and 5. We then get (x+8)(x+5). (Sorry lol this question is kind hard to explain over the computer.)
<span>Drag concentration( 360mg) per body surface (m2) is irrelevant to the infusion rate, which is volume divided by time, i.e. 150/(30/60) = 300ml/h</span>
Answer:
a horizontal line
Step-by-step explanation:
The hyperbola opens vertically, so the directrix is a horizontal line (a different one for each branch).
Answer: 0.2223mL
Step-by-step explanation:
Since the maximum significant figure in question is 4sf, our answer will be converted to 4sf.
Calculating 28.58/16×8.02 = 0.222377
= 0.2223mL to 4 significant figures
When the firecracker hits the ground, H(t) = 0.0 = -16t^2 + 90t + 160 Using the quadratic formula,t = (-90 +- sqrt(90^2 - 4(-16)(160))) / 2(-16)t = -1.42 ort = 7.04
The negative time is extraneous. Therefore,t = 7.04 s.
Seven Seconds is your answer!
