Step-by-step explanation:
k = √(49 - 12√5)
= √(45 + 4 - 2 √180)
= √45 - √4
= 3 √5 - 2.
<em>So, k + 2 = 3 √5 - 2 + 2 = 3 √5.</em>
66 is the answer for your questioj
Answer:
To find the maximum of a function in ax^2 + bx + c form, you can use the formula: maximum = c - (b^2 / 4a).
In this question, a = -16, b = 180, and c = 63.
Maximum = 63 - (180^2/4(-16))
Maximum = 569.25
Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.
Let me know if this helps!
The answer is 10x^4 - 2x^3
You plug in the point into each equation to see if the answer comes out equal. Such as the first one, so you have y=-3/4x+1. So you plug in the -4 for the x then plug in the -2 for y. So you get -2=1.1875, as you see both sides don't add up. As you progress in Algebra I'm guessing that you're in, you'll progress as the year goes on. So your answers are 3x-4y=-4 and y+2=3/4(x+4).
