Answer:
nth term = the previous number times 4(x-1)
Step-by-step explanation:
As you see the first tower has 1 then it is 5 for the next tower and then it is 13 for the next tower and then 25. Well this means that as you see, the expressions adds 4 to the previous 4 and then adds to the tower. Let me show you how it works.
Tower 1: 1
Tower 2: 1 + 4 = 5
tower 3 : 5 + 8 = 13
tower 4: 13 + 12 = 25
tower 5: 25 +16 = 41
The instruction booklet for a DVD
player says that the player uses about
0.4 kilowatt of electricity per hour. If
electricity costs $0.20 per kilowatt hour,
how much does it cost to run the player
for an hour?
Answer:
$.08
Step-by-step explanation:
it takes 0.4 per hour and it costs $0.20 per hour so you multiply the two numbers together.
0.4 x 0.20 = $.08

Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10.
What are Henry's chances of getting a second turn when he rolls the number cubes? (2 points)
Answer:
Step-by-step explanation:
The even numbers less than 10 are
2 which can only be done 1 way: when you roll snake eyes.
4 can be done 3 ways (2,2) (3,1) and (1, 3)
6 can be done 5 ways (2,4) (4,2) (5,1) (1,5) and (3,3)
8 can be done 5 ways (4,4) (2,6)(6,2)(5,3) and (3, 5)
There are 36 ways of throwing the number cubes.
We have a total of 5 + 5 + 3 + 1 = 14 ways

Find the 10th term of the geometric sequence 8,-16,32
Answer:
4096
GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.
I hope it help you
The required 10th term of the geometric sequence 8, -16, 32 is -4,096.
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.
r = (second term) / (first term) = (-16) / 8 = -2
So the common ratio is -2.
The nth term of a geometric sequence is given by the formula:
[tex]a_n = a_1 * r^{(n-1)}[/tex]
where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.
To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:
[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]
Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.

Find the slope of the line that passes through the pair of points
(3,-3), (3,-4)
A undefined
B 0
C -7/6
D -6/7
Answer:
undefined
Step-by-step explanation:
To find the slope through 2 points
m = ( y2-y1)/(x2-x1)
= ( -4 - -3)/(3 - 3)
= ( -4+3)/(3-3)
= -1/0
Since it is a number divided by zero, the slope is undefined

Step-by-step explanation:
Δ ABC and Δ DEF are congruent, same 3 angles in the same position in both triangles, so
Corresponding sides will be congruent, that is
x = ED = BA = 73
I need help I will give brainliest
Answer:
Step-by-step explanation:
5). Triangle DEF is an equilateral triangle.
Therefore, measure of all sides and the angles of the triangle will be equal.
DE = EF = DF = 5.2 ft
3y + 1 = 5.2
3y = 5.2 - 1
3y = 4.2
y = 1.4
Similarly, m∠D = 60° [Measure of all angles of an isosceles triangle = 60°]
(5x)° = 60°
x = [tex]\frac{60}{5}[/tex]
x = 12
6). Property to be used in ΔFGH,
"Two sides of an isosceles triangle are equal in measure and opposite angles of the equal sides of the triangle are equal"
FG = GH
3y = 12.9
y = 4.3
m∠F = m∠H
4x = 44
x = 11
HELP!!!! In Ottawa you can ride on a tour bus for a fixed price plus a variable amount that depends on the length of the trip. the variable cost is $2/km and 20km trip cost $55
Determine the equation relating cost, C, in dollars, and distance, d, in kilometers.
Answer:
C = 2d + 15
Step-by-step explanation:
$2 per km, so $40 for 20km.
55-40 is 15 so $15 is a fixed price.

A graph shows water (cups) labeled 1 to 9 on the horizontal axis and time (minutes) on the vertical axis. A line increases from 1 to 8.
What feedback should another lab group give during a peer review of the work?
The line of best fit is reasonable because it does not go through any points.
The line of best fit is reasonable because it goes through the largest cluster of points.

A solid sphere is cut into 4 equal wedges the volume of each wedge is v=1/3r3 solve the volume for r
Answer:
r = (3V/π)^1/3
Step-by-step explanation:
Given that :
Volume of a sphere = V = 4/3πr³
Dividing into 4
4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³
V = 1/3πr³
Cross multiply
3V = πr³
Divide both sides by π
3V/ π = πr³/ π
3V/ π = r³
Take the cube root of both sides
r = (3V/π)^1/3
