1) 1/4+1/2
We need to convert the fractions.
1/4 is fine.
1 x 2=2
2 x 2=4
1/4+2/4=3/4
2) a+a
a can be written as 1a.
1a+1a=2a
I can't see photos and he doesn't know 3 or 4 and i'm confused on 5.
a=?
Hope it helps?
It's a 45-45-90 triangle,
where the legs are congruent, and the hypotenuse is sqrt(2) times the length of a leg.
180 °- 121°
= 59°
the answer is 59°
Answer:
y = -2(x + 1)^2 + 8
Step-by-step explanation:
The equation of a parabola can be written in the form;
y = a(x-h)^2 + k
where a is the multiplier (h,k) is the vertex
so h = -1 and k = 8
Plug in these values
y = a(x + 1)^2 + 8
So to get the value of a, we use the point where the parabola passes through which is the point (1,0)
Simply substitute the values of x and y
0 = a(1 + 1)^2 + 8
0 = a(2)^2 + 8
-8 = 4a
a = -8/4
a = -2
So therefore the equation of the parabola is ;
y = -2(x + 1)^2 + 8
