I'll do the first one to get you started
The equation y = x^2+16x+64 is the same as y = 1x^2+16x+64
Compare that to y = ax^2+bx+c and we see that
a = 1
b = 16
c = 64
Use the values of 'a' and b to get the value of h as shown below
h = -b/(2a)
h = -16/(2*1)
h = -8
This is the x coordinate of the vertex.
Plug this x value into the original equation to find the corresponding y value of the vertex.
y = x^2+16x+64
y = (-8)^2 + 16(-8) + 64
y = 0
Since the y coordinate of the vertex is 0, this means k = 0.
The vertex is (h,k) = (-8, 0)
---------------------
So we found that a = 1, h = -8 and k = 0
Therefore,
f(x) = a(x-h)^2 + k
f(x) = 1(x-(-8))^2 + 0
f(x) = (x+8)^2
is the vertex form
---------------------
<h3>Final answer to problem 1 is f(x) = (x+8)^2 </h3>
Answer:
a)7, b)-40
Step-by-step explanation:
a) 5(x-1)=30
=>5x -5=30
=>5x=30+5
=>5x=35
=>x=35/5
so, x=7
b)3(x+10)-2(x-5)=0
=>3x+30-2x+10=0
=>x+40=0
so,x=-40
10 meters = 1 dekameter
So multiply by 4
10 x 4 = 40
40 meters in a dekameter
Answer:
the answer for this question is 414
Answer:
57.6 ft squared
Step-by-step explanation:
diverse 9.6 and 8 to get the number you multiply 5 with. Then you get the side length of the other side. You then multiply both of those numbers together. Hope this helps!! Please mark me as brainliest :)
