Step-by-step explanation:
ax^2+bx+c=0
a=leading term
ok so if the leading term is positive then opens up and has a <u>min</u>
if leading term is negative then opens down and has a <u>max</u>
leading term is positive
1x^2+8x
it has a min
to complete the square, move c aside take 1/2 of b and square it
b=8
8/2=4
4^2=16
now add that to both sides
x^2+8x+16+6=0+16
factor perfect square
(x+4)^2+6=16
subtract 6
(x+4)^2=10
subtract 10
(x+4)^2-10=0
vertex aka min or max is (h,k) when ou have
y=a(x-h)+k
h=-4
k=-10
Answer:
B) (-1,1)
Step-by-step explanation:
When you look at the distance between points A and D, you can see that they have a distance of 2 units. So, when you translate the figure to it's new coordinates, point D should now have the coordinates of (-1,1).
Hope this helps! :)
Answer:
The value of x to the nearest tenth is, 15.5 degree
Step-by-step explanation:
Given that:
To find the value of x;
Take inverse of sin both sides we have;
Simplify:
Simplify:
Therefore, the value of x to the nearest tenth is, 15.5 degree
Hello,
The longer diagonal is an axis of symmetry of the Kite.
So E is the middle of BD and BE=8/2=4
Answer A: 4in.
Answer:
For the triangles just use the equation a^2 + b^2 = c^2. c is the hypotenuse and a and b are the other two sides. if you have at least 2 of the sides you can change the equation to find the other side. Now for the second shape (the weird rectangle-triangle thingy) you just have to do 17-11= 6 witch gives you a. B is already given to you b = 8, so all you have to do is 6^2 + 8^2 witch is 100 then you can square root it with becomes 10. so your x = 10 for that shape.
