Answer:
a³+2a³+5
Step-by-step explanation:
7a³+14a+12+{-6a³}+12a²-7
=<u>7a³-6a³</u>+<u>14a+12a²</u>+<u>12-7</u>
=a³+2a³+5
Answer:
approx 7.81 Exactly: √61
Step-by-step explanation:
Use Pythag theorem: 5^2 + 6^2 = hyp^2 (line AS)
25 + 36 = 61
hyp = √61 or about 7.81
Let s =student
a =adults
now using the context to make an equation,
200s + 150a - 200 = 1000
the - 200 is the expenses you lost hosting the talent show.
now clean up the equation, add 200 to both side.
200s + 150a = 1200
Step-by-step explanation:
Answer:
Last choice is correct.
Step-by-step explanation:
Given that ∠C=90°, ∠B=30°, c=10
We know that sum of all angles in a triangle is 180 degree.
∠A+∠B+∠C=180°
∠A+∠30°+∠90°=180°
∠A+∠120°=180°
∠A=60°
Now we can use sin or cos whichever applicable to find missing sides
2b=10
b=5
Similarly
a=8.6602
Hence last choice is correct.
<u>Given</u>:
The given inequality is
We need to determine the graph that fits the inequality.
<u>Graph of the inequality:</u>
The inequality means that x is greater than 4. This means that the end value 4 is not included.
To graph the inequality " > " a dashed line is used.
The inequality does not contain any y - value in it.
Hence, it has only one vertical line at and is shaded for all values of x greater than 4.
Therefore, the graph that fits the inequality is a vertical dashed line, shaded to the right of the line.
Thus, Option d is the correct answer.
