Answers
Answer:
a=1; b=14
Step-by-step explanation:
you have to form a perfect square
(a+b)²=a²+b²+2ab
If you add a one you will get a perfect square
x²+2x+1 = (x+1)²
if you added a one in one side you have to added to the other side too
(x+1)² = 13+1
(x+1)² = 14
Answer:
a = 1, b = 14
Step-by-step explanation:
To complete the square
add ( half the coefficient of the x- term)² to both sides , that is
x² + 2(1)x + 1 = 13 + 1
(x + 1)² = 14
with a = 1 and b = 14

Volume = 4,410 yd

radius =
Answers
Answer:
Radius = 11.85yd
Step-by-step explanation:
Volume of a Cone formula: V = πr²(h/3)
We know that;
V = Volume
r = radius
π = pi (this is a sign located on your calculator)
h = height
We are given that;
V = 4,410
r = unknown
h = 30
Let's substitute the values in:
=> V = πr²(h/3)
=> 4,410 = πr²(30/3)
=> 4,410 = πr²(10)
=> 4,410 / 10 = πr²
=> 441 = πr²
=> 441 / π = r²
=> 140.37 = r²
=> [tex]\sqrt{140.37}[/tex] = r
=> 11.85 = r
Therefore, the radius of the cone = 11.85yd

Answers
Answer:
[tex]p(t) = \frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) }[/tex]
g(t) = 0
And
The differential equation [tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex] is linear and homogeneous
Step-by-step explanation:
Given that,
The differential equation is -
[tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex]
[tex]e^{t}y' + (9t - \frac{1}{t^{2} + 81 } )y = 0\\e^{t}y' + (\frac{9t(t^{2} + 81 ) - 1}{t^{2} + 81 } )y = 0\\e^{t}y' + (\frac{9t^{3} + 729t - 1}{t^{2} + 81 } )y = 0\\y' + [\frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) } ]y = 0[/tex]
By comparing with y′+p(t)y=g(t), we get
[tex]p(t) = \frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) }[/tex]
g(t) = 0
And
The differential equation [tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex] is linear and homogeneous.

The exact value of cot A will be 0.857.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The co-secant of angle A is √85 / 6. And that angle A is in Quadrant I.
Then the value of angle A will be
csc A = √85 / 6
1 / cos A = √85 / 6
cos A = 6 / √85
A = 49.4°
Then the exact value of cot A will be
cot A = cot 49.4°
cot A = 0.857
The exact value of cot A will be 0.857.

What is the recursive and explicit formula of the geometric sequence?
2,5, 12.5, 31.25, 78, 125, ...
Answers
Answer:
Option (2)
Step-by-step explanation:
Given geometric sequence is,
2, 5, 12.5, 31.25, 78.125......
First term = a₁ = 2
Common ratio of the sequence = r = [tex]\frac{5}{2}[/tex]
= 2.5
Recursive formula of a geometric sequence is given by,
[tex]a_n=a_{n-1}(r)[/tex]
Here, [tex]a_n=[/tex] nth term of the sequence
[tex]a_{n-1}=[/tex] (n - 1)th term
r = common ratio
Therefore, recursive formula for the given sequence will be,
[tex]a_1=2[/tex]
[tex]a_n=a_{n-1}(2.5)[/tex]
Explicit formula of a geometric sequence is given by,
[tex]a_n=a_1(r)^{n-1}[/tex]
Therefore, explicit formula of the sequence will be,
[tex]a_n=2(2.5)^{n-1}[/tex]
Option (2) will be the correct option.

Write a quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, −17) .
f(x)=
Answers
Answer:
Step-by-step explanation:
Given,
Vertex (h, k ) = (1,0)
Now,
We know,
f(x) = a(x-h)²+k
Since, it passess through (2, −17)
Put x = 2 and y = - 17
or, -17 = a(2 - 1)² + 0
or, -17 = a
Now,
f(x) = a(x - h)² + k
= -17(x - 1)² + 0
= -17x² + 34x - 17
