Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2( 
)x +
- - 5
y = (x + )² - - 
y = (x + )² - 
Hence
a = and b = -
Answer:

Answer:
Step-by-step explanation:
6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)
8/2= 4 cm is the radius and V = 4/3.π.64…..(2)
10/2=5 cm is the radius and V = 4/3.π.125…(3)
The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...
The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.
12 cms answer. Brainlist please?
