we are given two points as
A (1,5) and B (6,2)
so,
x1=1 , y1=5
x2=6 , y2=2
now, we can use distance formula
now, we can plug values
and we get
so, we will get
.........Answer
Answer:
1. area = pi*r^2
herein, dia = 20 inch
radius = 10 inch
area = 22/7*10*10
= 314.2 square inch
Step-by-step explanation:
Answer:
226.08 cm³
Step-by-step explanation:
Hi!
To find the volume of a cone, you do 1/3 (3.14) × r² × h.
So all we have to do is substitute 6 in our r and h spots.
1/3 (3.14) × (6²) × 6.
= 1/3 (3.14) × 36 × 6.
= 226.08
Thus, the answer is 
.
Hope this helps!
Graph B would be the best fit for the model.
Answer:
y = x² + 2x + 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 1, 4), thus
y = a(x + 1)² + 4
To find a substitute (0, 5) a point on the graph into the equation
5 = a(0 + 1)² + 4
5 = a + 4 ( subtract 4 from both sides )
a = 1, thus
y = (x + 1)² + 4 ← expand and simplify
= x² + 2x + 1 + 4
= x² + 2x + 5
