Answer:
See explanations below
Step-by-step explanation:
The given sequence 7,21,63... is geomertic in nature
The nth term is expressed as;
Tn = ar^n-1
a is the first term = 7
r is the common ratio = 21/7 = 63/21 = 3
n is the number of terms
Substitute
Tn = 7(3)^n-1
For the 12th term, when n = 12
T12 = 7(3)^12-1
T12 = 7(3)^11
T12 = 7(177,147)
T12 = 1,240,029
Hence the 12th terms is 1,240,029
For the recursive function
First term = 7(1)
2nd term T2 = 21 = 7(3)
3rd term T3 = 63 = 7(9) = 7(3^2)
Tn = 7(3^n)
Hence the recursive function is 7(3^n)

3х – 8y = 34
7х + 4у = -34
Solve by elimination
Y and x
Please show steps ):
Answer:
The answer would be (-2, -5)
Step-by-step explanation:
3x - 8y= 34
2(7x + 4y = -34)
3x - 8y=34
14x + 8y= -68
----------------------
17x= -34 divided by 17
x = -2
3(-2) -8y= 34
-6 -8y =34 add 6
-8y= 40 divide by -8
y = -5
if you want to check the answer replacing -2 for x and -5 for y
7(-2) + 4(-5)= -34
-14 + (-20) = -34
-34 = -34

De 40 estudiantes de undécimo grado, 14 toman clase de piano y 29 clases se violín.
a. Si cinco estudiantes toman ambas clases,¿ cuántos estudiantes no asisten a ninguna de las dos?
b. ¿cuántos estudiantes toman clase de piano o de violín?
c. cuántos estudiantes toman únicamente clases de violín?
Puedes separar los grupos en:
los que solo toman clases de piano; p
los que solo toman clases de violin: v
los que toman clases de piano y violin; 5
A) para determinar cuántos estudiantes no toman ni piano ni violin, podemos hallar el número total de estudiantes que toman clases solo de piano y los que toman solo de violín y los que toman ambas clases, de la siguiente forma:
Estudian solo piano, p = 14 - 5= 9
Estudian solo violín, v = 29 - 5 = 24
Estudian ambos: 5
Total de estudiantes que toman clases de esos instrumentos : 9 + 24 + 5 = 38
Por tanto, hay 40 - 38 = 2 estudiantes que no toman clases de piano ni violín.
B) ¿cuántos estudiantes toman clases de piano o violín?
Son los que tocan solo piano, o solo violín o ambos y los hallamos arriba: 9 + 24 + 5 = 38.
Respuesta: 38
C) ¿Cuántos estudiantes tocan solo violín?
También lo encontramos arriba: son 29 - 5 = 24

how many games have the hawks played?
4/8x - 6 = -24 solve for x
Answer:
Step 1: Simplify both sides of the equation.
4/8x−6=−24
1/2 x+−6=−24
1/2 x−6=−24
Step 2: Add 6 to both sides.
1/2 x−6+6=−24+6
1/2x=−18
Step 3: Multiply both sides by 2.
2*( 1/2
x)=(2)*(−18)

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Find the value of x.
Answer:
[tex]x=64^{\circ}[/tex]
Step-by-step explanation:
We know that sum of angles of a quadrilateral is equal to 360 degrees.
It means,
[tex]\angle X+\angle Y+\angle Z+\angle W=360\\\\100+130+66+x=360\\\\296+x=360\\\\x=360-296\\\\x=64^{\circ}[/tex]
So, the value of x is equal to [tex]64^{\circ}[/tex].

a 91.5 kg football player running east at 2.73 m/s tackles a 63.5 kg player running west at 3.09 m/s. what is their velocity afterward?
Answer:
2.88m/s
Step-by-step explanation:
By using the law of conservation of momentum
Initial momentum = final momentum
v = is their combined velocity afterwards
Solving equation (1) for v
V = 2.88 m/s
Therefore the velocity afterward is 2.88 m/s.

Question 13
Find the angle between the given vectors to the nearest tenth of a
degree.
u= <8,4, v = <9.-9> (5 points)
Answer:
71.6 degrees
Step-by-step explanation:
Given the vectors
u= <8,4> v = <9.-9> (5 points)
u*v = (8, 4)*(9, -9)
u*v = 8(9)+(4)(-9)
u*v = 72 - 36
u*v = 36
|u| = √8²+4²
|u| = √64+16
|u| = √80
|v| = √9²+9²
|v| = √81+81
|v| = √162
Using the formula
u*v = ||u||v| cos theta
36 = √80(√162)cos theta
36 = √12960 cos theta
cos theta = 36/√12960
cos theta = 36/113.8
cos theta = 0.3162
theta = arccos(0.3162)
theta = 71.56 degrees
Hence the angle between the given vectors to the nearest tenth of a
degree is 71.6 degrees
Between 9:00 a.m. and 10:20 a.m., 18,000 visitors
entered the Family Fun Amusement Park. Between
9:00 a.m. and 10:20 a.m., an average of how many
visitors per minute entered the park?
Answer: 225
Step-by-step explanation: 18,000 divided by 80 minutes wich is 1 hour and 20 minutes is 225
The average of visitors entry in park per minute is 225.
What is average?A number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.
Given,
Total number of visitors entered in park Between 9:00 a.m. and 10:20 a.m. = 18000
There is total of 80 minutes Between 9:00 a.m. and 10:20 a.m.
Average of visitors entry in park per minute = [tex]\frac{18000}{80}[/tex]
= 225
Hence, average of visitors entry in park per minute is 225.

a.) $32.00 a ticket
b.) $39.00 a ticket
c.) $34.00 a ticket
Answer:

Step-by-step explanation:
40× 15 out of 100 =6
40-6=34
Answer:
c.) $34.00 a ticket
Step-by-step explanation:
Since you're trying to figure out how much a discounted ticket is you have to take the 15% off. So 15% of 40 is 6. Now take the 6 off of 40 (40-6) you will get 34. So the answer is $34.
