Answer:
1533.88261311522
Step-by-step explanation:
<em>Let r be the radius of the (base/circle)</em>
<em>and L be the slant height of the cone</em>
<em>Formula ………………………………………………………………………………………………………</em>
The surface area of a cone = the (curved/lateral) surface area + the base
=========================================
L = BC = 36
The answer to this question is
B. (x+7)²+(y-4)²=64
I hope this helps!!!!!!!
The correct answer is number one
Answer:
(- 4, 27 )
Step-by-step explanation:
Equate the right sides of both equations, that is
x² - 2x + 3 = - 2x + 19 ← subtract - 2x + 19 from both sides
x² - 16 = 0 ← in standard form
(x - 4)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 4 = 0 ⇒ x = - 4
Substitute these values into f(x) = - 2x + 19
f(4) = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )
f(- 4) = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )
