represents a geometric sequence. Let Q= -5.
Which equation is an explicit formula that represents the sequence?
Answers
Explanation: the equation for explicit formula is a (a 1 at the bottom of a) times r to the power of n minus 1
a with the 1 at the bottom just means your first term, which is -5.
R is Q which is -5
When you put that together you get -5 * -5^n-1
(The asterisk(*) means multiplication and the caret(^) means the variables and numbers after it are in exponent form.

Determine the value of k if g(x)=4x+k is a tangent to f(x)=-x²+8x+20
Answers
Answer:
k=24
Step-by-step explanation:
The tangent of the function f at x=a, can be found by differentiating f w.r.t. x and then replacing x with a.
f=-x^2+8x+20
Differentiating both sides:
f'=(-x^2+8x+20)'
By sum rule:
f'=(-x^2)'+(8x)'+(20)'
By constant multiple rule:
f'=-(x^2)'+8(x)'+(20)'
By constant rule:
f'=-(x^2)+8(x)'+0
By power rule:
f'=-2x+8
f' at x=a is -2a+8
This is the slope of any tangent line to the curve f.
The slope of g is 4 if you compare it to slope intercept form y=mx+b.
So we gave -2a+8=4.
Subtracr 8 on both sides: -2a=-4
Divide both sides by -2: a=2
The tangent line to the curve at x=2 is y=4x+k.
To tind y we must first know the y-coordinate of the point of tangency.
If x=2, then
f(2)=-(2)^2+8(2)+20=-4+16+20=12+20=32
So the point is (2,32).
g(x)=4x+k and we know g(2)=32.
This gives us:
32=4(2)+k
32=8+k
k=32-8
k=24
From the tangent given, the value of k will be 24.
How to solve the tangentFrom the information given, g(x) = 4x + k and this is a tangent to f(x)= -x² +8x + 20.
f(x)= -x² +8x + 20
= f'(x) = -2x + 8
The slope of tangent = -2x + 8 at (x , y)
g(x) = 4x + k
Hence, slope = 4
-2x + 8 = 4
Collect like terms
-2x = 4 - 8
-2x = - 4
Divide both side by -2
-2x/-2 = -4/-2
x = 2
f(x)= -x² +8x +20
where, x = 2
y = -2² + 8(2) + 20
y = 32
Hence (2 , 32) lies on g(x)= 4x+k
32 = 4(2) + k
32 = 8 + k
k = 32 - 8
k = 24
In conclusion, the value of k is 24.

The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)

Answer:

Step-by-step explanation:
Given
x² - 21x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 21)
The factors are - 24 and + 3, since
- 24 × + 3 = - 72 and - 24 + 3 = - 21 , then
x² - 21x - 72 = (x - 24)(x + 3) ← in factored form
