Answer:
200π m²
Step-by-step explanation:
Lateral area of a cone = πrl
r = 8 m
l = 25 m
Plug in the values
Lateral area = π × 8 × 25
Lateral area = π × 200 = 200π m²
A1=8
common ratio=r
sum of 6 terms
S=a1+a2+a3+...+a6
=a1(1+r+r^2+...+r^5)
=a1(r^6-1)/(r-1)
but we're given S=74648
=>
8(r^6-1)/(r-1)=74648
Cross multiply and solve for r (by trial and error)
r^6-1=9331(r-1)
r=6
so
a(3)=a1*r^(3-1)
=8*(6^2)
=288
Answer:
17
Step-by-step explanation:
You need to divide:
8 1/2 / 1/2
=17/2 x 2/1
= 17
Answer:
y + 16 = 3(x + 5)
Step-by-step explanation:
When you write an equation in point-slope form, you only need two things: a point and a slope.
Given:
The standard point-slope equation is
y - y₁ = m(x - x₁)
Plug in what you know.
y - (-16) = 3(x - (-5))
Simplify.
y + 16 = 3(x + 5)
This is your equation.

Answer:
Step-by-step explanation:
Rewrite 7(x+5)/(x-3)(x+5) for greater clarity:
7(x+5)
--------------
(x-3)(x+5)
Now cancel the x + 5 terms. We get:
7
-----------
x - 3
