Answer: The term to term rule is an Arithmetic progression for the two question. B) 1Oth term for the first is 30 and for the second series is 59
Step-by-step explanation:
4.1) 3 6 9 12 15
For the sequence above, we can see that the next term is gotten by addition of 3 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =3
And d common difference =3(6-3,9-6,12-9)
10th term=
T10 = 3+ (10 - 1)3.
T10 = 3+ (9)3.
T10 = 3+ 27.
T10 =30
4.2) 5 11 17 23 29
For the sequence above, we can see that the next term is gotten by addition of 6 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =5
And d common difference =6 (11-5, 17-11,23-17)
10th term=
T10 = 5+ (10 - 1)6.
T10 = 5+ (9)6.
T10 = 5+ 54.
T10 =59
Find the length of each arc
Answer:
27 pi/4 or 6 3/4 pi
Step-by-step explanation:
First find the circumference
C = 2*pi*r
C = 2 * pi *9
C = 18 pi
The find the fraction of the arc
A circle is 360 degree
135/360 =3/8
Multiply the circumference by the fraction
18 pi * 3/8 =
27 pi/4
6 3/4 pi
More help with cylinder math?
Answer:
[tex]V=706.5[/tex] [tex]ft^3[/tex]
Step-by-step explanation:
Since it's saying, "how much water does your neighbor need to completely fill his pool", it's asking for us to find the volume of the pool because the volume is the amount of space inside the pool which will be filled with water.
The volume formula for a cylinder: [tex]V=\pi r^2h[/tex]
In the text, since they gave the diameter and not the radius, we need to find the radius by dividing the diameter by two: [tex]\frac{15}{2}=7.5[/tex]
Now, we can start solving.
[tex]V=(3.14)(7.5^2)(4)[/tex]
[tex]V=(3.14)(56.25)(4)[/tex]
[tex]V=(3.14)(225)[/tex]
[tex]V=706.5[/tex]
Hope this helps

I need help with this
Answer:
Step-by-step explanation:
the given equation is in the form of quadratic formula i.e.ax^2+bx+c=0.
So ,here a=-1 ,b=-6 and c=-9
b^2=(-6)^2
=36
4ac=4*(-1)*(-9)
=4*9
=36
b^2-4ac=36-36
=0
number of solutions =1
Given the following terms of a geometric sequence: a1=7, a11=7340032 ; Determine r and a8
Answer:
r = 4
a8 = 114,688
Step-by-step explanation:
a1=7
a11 = 7340032
a11 = a1*r^10
7340032 = 7 * r^10
7340032 = 7r^10
r^10 = 7340032/7
r^10 = 1,048,576
Find the 10th root of both sides
10√r^10 = 10√1,048,576
r = 4
a8 = a1 * r^7
= 7 * 4^7
= 7 * 16,384
= 114,688
a8 = 114,688

Solve the system of equations. y=23x–19 x2–y= – 6x–23 Write the coordinates as integers, simplified proper or improper fractions, or simplified radical expressions.
Answer:
(3, 50) and (14,303)
Step-by-step explanation:
Given the system of equations;
y=23x–19 ....1
x²–y= – 6x–23 ...2
Substitute 1 into 2;
x²–(23x-19)= – 6x–23
x²–23x+19= – 6x–23 .
x²-23x + 6x + 19 + 23 = 0
x² - 17x + 42 = 0
Factorize;
x² - 14x - 3x + 42 = 0
x(x-14)-3(x-14) = 0
(x-3)(x-14) = 0
x = 3 and 14
If x = 3
y = 23(3) - 19
y = 69-19
y = 50
If x = 14
y = 23(14) - 19
y = 322-19
y = 303
Hence the coordinate solutions are (3, 50) and (14,303)

The probability of winning a game is 0.37, and a tie is not possible. The probability of losing the game is
A. 0.37
B. 0.50
C. 0.63
D. unable to be determined
Help me plssss
Answer:
C
Step-by-step explanation:
Because there are only two outcomes (winning or losing) this means that
P(winning)+P(losing)=1
if we knowing that P(winning)=.37 we can write
.37+P(losing)=1
1-.37=P(losing)
.63=P(losing)

On a coordinate plane, point B is at (1, negative 1). Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3? (1, –1) (3, –3) (–2, 2) (–6, 6)
Answer:
(3,-3)
Step-by-step explanation:
If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)
Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)
Hence the required coordinate will be (3,-3)

Maria tutors history. For each hour that she tutors, she earns 20 dollars. Her earnings, E (in dollars), after tutoring for h hours is given by the following.
E=20h
How much does Maria earn if she tutors for 5 hours?
Answer:
Maria earns 100 dollars
E=100
Step-by-step explanation:
if E=20h and they want to know how much Maria will make in 5 hours substitute the h for 5. 20 x 5 =100
E=100
Answer:
100
Step-by-step explanation:
The equation is E=20h
E is the amount she earns.
20 is the amount of money she earns per hour.
h is the amount of hours she worked.
She worked 5 hours. h represents hours so plug in 5 where h is in the equation.
E=20h
E=20(5)
E= 20×5
E=100
Which statement describes why the system has two solutions?
Train A leaves Paris and travels at a constant speed of 75 mph toward Pisa. At the
same time. Train B leaves Pisa headed toward Paris at a constant speed of 50
mph. Let x represent time traveled in hours and let y represent miles from Paris. If
Paris and Pisa are 500 miles apart, when will the two trains pass each other?
Answer: [tex]4.016\ hr[/tex]
Step-by-step explanation:
Given
Train A has speed of [tex]v_a=75\ mph[/tex]
Train B has speed of [tex]v_b=50\ mph[/tex]
If Paris and Pisa is 500 miles apart
If they meet x hours after the start
The sum of the distances traveled by Train A and B is 500 miles
[tex]\Rightarrow 75\times x+50\times x=500\\\Rightarrow 125x=500\\\Rightarrow x=4.016\ hr[/tex]
So, after [tex]4.016\ hr[/tex] they will pass each other.

4^2 -2×3+6=16 is your answer
Answer:
Step-by-step explanation:
P means parenthesis, of which we have none. So we move to E, which is exponents, which we do have. So we start there:
[tex]4^2-2*3+6[/tex] becomes
16 - 2 * 3 + 6. Now we have to do multiplication/division in the order we come to it in the problem. That means multiplying 2*4 first:
16 - 6 + 6. Now we do addition/subtraction in the order we come to it in the problem:
16- 6 + 6 = 10 + 6 = 16

which equations results from adding the equations in this system?
x+6y=9
-x+2y=-15
Answer:
8y = -6
Step-by-step explanation:
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers.
9 + (-15) = -6
