Given:
[tex]b(1)=-12[/tex]
[tex]b(n)=b(n-1)\cdot 4[/tex]
To find:
The third term of the sequence.
Solution:
We have,
[tex]b(n)=b(n-1)\cdot 4[/tex]
For n=2, we get
[tex]b(2)=b(2-1)\cdot 4[/tex]
[tex]b(2)=b(1)\cdot 4[/tex]
[tex]b(2)=-12\cdot 4[/tex] [tex][\because b(1)=-12][/tex]
[tex]b(2)=-48[/tex]
For n=3, we get
[tex]b(3)=b(3-1)\cdot 4[/tex]
[tex]b(3)=b(2)\cdot 4[/tex]
[tex]b(3)=-48\cdot 4[/tex] [tex][\because b(2)=-48][/tex]
[tex]b(3)=-192[/tex]
Therefore, the 3rd term of the sequence is -192.

tan(x)/sec(x)=sin(x)
Answer:
(identity has been verified)
Step-by-step explanation:
Verify the following identity:
tan(x)/sec(x) = sin(x)
Hint: | Eliminate the denominator on the left hand side.
Multiply both sides by sec(x):
tan(x) = ^?sec(x) sin(x)
Hint: | Express both sides in terms of sine and cosine.
Write secant as 1/cosine and tangent as sine/cosine:
sin(x)/cos(x) = ^?1/cos(x) sin(x)
Hint: | Come to a conclusion.
The left hand side and right hand side are identical:
Answer: (identity has been verified)

A line that passes through the points whose coordinates are (1,1) and (5,7)
is dilated by scale factor of 3 and centered at the origin. The image of the line
a) is perpendicular to the original line
b) is parallel to the original line
c) passes through the origin
d) is the same line
Answer:
B
Step-by-step explanation:
The image that the line will produce would be:
b). is parallel to the original line.
Given that,
Coordinates = [tex](1,1) and (5,7)[/tex]
Scale factor [tex]= 3[/tex]
As we know,
Slope [tex]= \frac{y_{2} - y_{1} }{{x_{2} - x_{1}} }[/tex]
where;
[tex]y_{2} = 7[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 5[/tex]
[tex]x_{1} = 1[/tex]
By putting these values,
Slope [tex]= (7 - 1)/(5-1)[/tex]
[tex]= 6/4[/tex]
[tex]=[/tex] [tex]1.5[/tex]
∵The image of the line would be ║ to the original line.
Thus, option b is the correct answer.

What is the end behavior f(x) ?
[tex]\text{ as } x \to \infty, \ f(x) \to \infty\\\\\text{ as } x \to -\infty, \ f(x) \to -\infty[/tex]
In other words, as x gets really large in the positive direction, so does f(x).
As x gets really large in the negative direction, so does f(x). We can see that x and f(x) move in the same direction toward the same type of infinity.
In laymen's terms or in plain English, we can say that "The graph falls to the left and rises to the right". We don't worry about the wiggle motion in the middle, since all we care about is what's going on as x goes to either infinity.
"Falls to the left" means it goes down forever as we move leftward. "Rises to the right" means it goes up forever as we move to the right. This type of behavior of "falls to the left and rises to the right" is indicative of any odd degree polynomial where the leading coefficient is positive. In this case, it appears we're dealing with a cubic function of degree 3.

5(x-4)+2x=14 help me find the answer x=?
Answer:
x = - 6/7
Step-by-step explanation:
Distribute 5 (x - 4) first --> 5x - 20
Combine like-terms: 5x - 20 + 2x = 14 --> 7x - 20 = 14
Subtract 20 on both sides: 7x = -6
Divide both sides by 7: x = -6/7
If the scale factor is 5/3 what is the width of the new rectangle?
Answer:
If 24 is the width then the answer is 40 and if 30 is the width then the answer is 50
Step-by-step explanation:
We multiply both sides by the scale factor to find both sides of the new rectangle. 30 * 5/3 = 50 and 24 * 5/3 = 40, so the sides of the new rectangle are 50 and 40. It matters whether 24 or 30 are the length or width, but if 24 is the width then the answer is 40 and if 30 is the width then the answer is 50
Please help!!! Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y= -2x^2 + 105x – 859
Answer:
519
Step-by-step explanation:
or 519.125
The maximum amount of profit the company can make, to the nearest dollar should be considered as the $519.
Calculation of the maximum amount of profitSince the amount of profit made expressed as [tex]y=-2x^2+105x-859[/tex]
Now
At maximum profit, dy/dx = 0
So,
dy/dx = -4x + 105
0 = -4x + 105
4x = 105
x = 105/4
x = 26.25
Now
[tex]y=-2x^2+105x-859\\\\y=-2(26.25)^2+105(26.25)-859[/tex]
y = - 1,378.125+2,756.25-859
y = 519.125
Hence the maximum amount of profit the company can make is $519.

Each straight piece of wire is the diagonal of a square that is 3" on a side. The Pythagorean theorem tells you the length of that diagonal is ...
d = √(3^2 +3^2) = √18 = 3√2 . . . inches
There are 4 such diagonals on each trivet, so the total length of wire for 12 trivets is ...
(12)(4)(3√2) = 144√2 . . . inches
At a cost of $0.54 per inch, the total cost for 12 trivets will be ...
($0.54)(144√2) = $109.97

Arc length=∅/360×2πr (can't find the symbol of theta, use ∅ instead LOL)
[tex]\frac{\theta }{360}\cdot 2\pi \left(11\right)=16[/tex]
[tex]\frac{\theta }{360}=\frac{16}{22\pi }[/tex]
[tex]\theta \:=\frac{16}{22\pi \:}\cdot 360[/tex]
[tex]{\theta}=83.34[/tex]
Answer:
≈ 1.5 radians
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
Here arc = 16 , then
2πr × [tex]\frac{0}{2\pi }[/tex] = 16 ← cancel the 2π on numerator/denominator
11 ×θ = 16 ( divide both sides by 11 )
θ ≈ 1.5 radians ( to the nearest tenth )
