Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1

Answer:
Angle 2=160
Angle 3=10
Step-by-step explanation:
The rhombus is made up of two isoceles triangle.
Angle 1 measures 160.
Since the triangle is a isoceles triangle, the opposite angles of the congruent sides is equal angles to each other.
So the reamaing angles in the top triangle are equal so we can use this equation
Remeber that triangle maximum degree it can hold is 180
[tex]160 + x + x = 180[/tex]
[tex]160 + 2x = 180[/tex]
[tex]2x = 20[/tex]
[tex]x = 10[/tex]
We have two congruent triangle side they share Three sides. SSS
This means the corresponding angle of Angle 1 is Angle 2.
Angle 2=Angle 1 by CPCTC.
Angle 2=160
Angle 3 corresponds with one of the remaining congruent angles so it measures
10.

The Reeds are moving across the country. Mr. Reed leaves 4.5 hours before Mrs. Reed. If he averages 40mph and she averages 60mph, how many hours will it take Mrs. Reed to catch up to Mr. Reed?
Answer:
Mr. Reed DATA:
rate = 40 mph ; time = x hrs ; distance = 40x miles
-----
Mrs. Reed DATA:
rate = 60 mph ; time = x - 3.5 hrs ; distance = 60x - 210 miles
Equation:
40x = 60x -210
-20x = -210
x = 10.5 hrs
x-3.5 = 7 hrs (Mr. Reed's time)

2. Jacquelyn has 50 vocabulary words to study for an exam. She creates a flashcard for each word to study. Day 1 she studies 10 of the flash cards. Day 2 she studies the same 10 cards from the first day along with 5 new cards, for a total of 15 cards. Day 3 she studies the 15 cards she studied on the second day along with 5 new cards, for a total of 20 cards. Jacquelyn continues to increase the number of cards she studies each day by 5.
(a) Write a recursive rule to represent the number of cards Jacquelyn studies on day n.
(b) Write an explicit rule to represent the number of cards Jacquelyn studies on day n.
(c) On which day will Jacquelyn first study all 50 vocabulary cards?

f(x) = x^2 is stretched vertically by a factor of 4 and shifted 1 unit down.
equation = ???
Answer:
f(x) = 4x² - 1
Step-by-step explanation:
The given function is; f(x) = x²
Now, when stretched vertically by a factor of 4, we have;
f(x) = 4x²
It's now shifted 1 unit down.. Thus, the final function will be;
f(x) = 4x² - 1

What is the total surface area of the following square pyramid?
Answer:
The surface area of a square pyramid is the sum of the areas of all its 4 triangular side faces with the base area of the square pyramid. If a, h, and l are the base length, the height of the pyramid, and slant height respectively, then the surface area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

Jules owns a square plot of land that measures 30 yards on each side. He plans to divide the land in half by building a fence as shown by the dotted line below. how many yards of fencing does Jules need
A 15yd
B 30 yd
C 30/2yd
D30/2yd
Answer:
BD = 30√2 yd
Step-by-step explanation:
The shape of the land is a square with 30 yd side length on each side.
The fence to he built is the diagonal of the square BD.
Apply pythagorean theorem to find the number of yards of fencing (BD) he needs.
Thus:
BD² = BC² + CD²
BD² ° 30² + 30²
BD² = 1800
BD = √1800
BD = √(900*2)
BD = 30√2 yd

A piece of rope that is 26feet long is cut into two pieces. One piece is used to form a circle and the other used to form a square. Write a function g representing the area of the square as a function of the radius of the circle r.
9514 1404 393
Answer:
g(r) = (13 -πr)²/4
Step-by-step explanation:
The circumference of the circle is given by ...
C = 2πr
The amount of rope remaining after the circle is formed will be ...
26 -2πr
When this is used to form a square, each side of the square will be 1/4 of this length, so is ...
s = (26 -2πr)/4 = (13 -πr)/2
The area of the square is the square of the side lengths, so is ...
g(r) = ((13 -πr)/2)²
g(r) = (13 -πr)²/4 . . . . area of the square as a function of circle radius
