Answer: n( 8+6) because it shows the sum of n and the sum of 8+6 seperately like in the sentence.
Answer:
-2 sqrt(15)
Step-by-step explanation:
sqrt(-15) sqrt(-4)
We can use sqrt(ab) = sqrt(a) sqrt(b)
sqrt(-1) sqrt(15) * sqrt(-1) * sqrt(4)
We know the sqrt(-1) = i
i * sqrt(15) * i * 2
2i^2 sqrt(15)
i^2 = -1
-2 sqrt(15)
$79.65 is the correct answer
19. It notes or hints to using the quadratic formula because the equation can not be solved by factoring alone. Thus you must use the quadratic formula.
A=-16 B=25 C=3
It is so hard to type a normal equation let alone one of the quadratic formula so I will just attach a picture instead.
However you will end up getting two roots/zeros/x-intercepts of -0.11 and 1.67.
However since it is an application question asking for answers only in the first quadrant you must choose the positive x-intercept.
Therefore the water balloon will land at 1.67 seconds.
20. This question is very simple as it asks you to find a height at a given time. You simply put the given time (1second) into the equation and get your answer.
h=-16(1)^2+25(1)+3
h=12
Also don't mind my little scribble there. :)
C. 4
Because the rule of the graph is $1.50 per pound of apple, so you have to divide $6.00 by $1.50 and that gives you the answer.
