Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
19, 10, 1, ...
Answer:
arithmetic sequence
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 10 - 19 = 1 - 10 = - 9
This means the sequence is arithmetic

Step-by-step explanation:
Answer:
the value of 7x-y is -14.
Step-by-step explanation:
When x=2 and y=4,
To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.
7x - y = 7(2 - 4)
14 - 28
= -14.

Give the domain and range of T.
Write your answers using set notation.
Answer:
The sets of the domain and the range of T are, respectively:
[tex]Dom \{T\} =\{-3,0,3\}[/tex]
[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]
Step-by-step explanation:
The values of the relation T that belongs to the domains correspond with the values on the x-axis and associated with the given points, whereas the range corresponds with the respective values of the y-axis. Let [tex]T = \{(x,y)|(-3,3),(3,2),(0,-3),(3,-4)\}[/tex]
The sets of the domain and the range of T are, respectively:
[tex]Dom \{T\} =\{-3,0,3\}[/tex]
[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]

Describe how probability and odds are related.
Answer: The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

What is the solution to the system of equations below?
y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)
Answer:
(-10,-7)
Step-by-step explanation:
the given equations: y=-3 and x=-10
we can substitute the x in the first equation as -10.
y=(2/5×-10)-3
simplify
y=(2/1*-2)-3
y=-4-3
y=-7
the y value is -7
we actually have the x value given as -10 (in the system)
So the answer is (-10,-7)

Joey is building a doghouse. He measures the lengths of two sides and the hypotenuse to make sure the boards create a right triangle.
Which of the measurements below could be used to create the right triangle?
5 in, 7 in, 12 in
8 in, 12 in 14 in
5 in, 9 in, 11 in
6 in, 8 in, 10 in
pleasee help mee
Answer: 6in, 8in, 10in
6 squared + 8 squared equals to the radical of 100, which equals to 10 because 10 squared is.. 100
The measurements that can be used to build a right-angled triangle are
[tex]6 in, 8 in, 10 in[/tex]
The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship
[tex]x^2+y^2=z^2[/tex]
The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since
[tex]5^2+7^2=74\ne12^2[/tex]
The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since
[tex]8^2+12^2=208\ne14^2[/tex]
The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since
[tex]5^2+9^2=106\ne11^2[/tex]
The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since
[tex]6^2+8^2=100=10^2[/tex]
So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

7. A cone has a volume of 942 cubic inches
and a height of 9 inches. What is the radius of
the cone?
Answer:
Step-by-step explanation:
V of a cone V=3.14* r^2*h/3
942=3.14*r^2*9/3
r^2=942/(3.14*3)=100
r=sqrt100=10
The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.
Calculation of the radius of the cone;
Since there is a volume of 942 cubic inches and a height of 9 inches
We know that
Volume of a cone V=[tex]3.14* r^2*h/3[/tex]
So,
[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]
r =[tex]\sqrt 100[/tex]
=10
hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

how do you work out this equation?
solve simultaneous equations by substitution
x + y =3
5x + y = 15
Step-by-step explanation:
x + y = 3. => y = 3 - x
5x + y = 5x + (3 - x) = 15.
=> 4x + 3 = 15
=> 4x = 12, x = 3.
Therefore y = 3 - (3) = 0.
The solutions are x = 3 and y = 0.
Answer:
Step-by-step explanation:
x+y=3
5x+y = 15
I method:
y = 3 - x. substitute this in 2nd equation
5x + (3-x) = 15
5x + 3 - x = 15
4x = 12
x=3
y=0
II method:
subtracting 2nd equation and 1st equation we get
4x +0y = 12
x = 3
y = 0

how to calculate the volume of a cylinder if the height is 9.25 cm and the base is 6.5 cm
Answer:
306.94 cm
Step-by-step explanation:
The formula for volume of a cylinder is pi×r^2×h. Im assuming that you mean that the base is 6.5 cm in diameter so in this case you would plug in the values and do pi×3.25^2×9.25 and get 306.94 cm

8x2 + 54x + 27
12x2 - 27
8x2 + 60x - 27
12x2 + 48x - 27
Answer:
I think is 12x2 +48x-27 but I'm confused
Answer:
[tex]A=12x^2+48x-27[/tex]
Step-by-step explanation:
Area of a Rectangle
The image shows a rectangular vegetable garden with different crops.
The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.
The area of a rectangle is:
A = WL
[tex]A=(2x+9)(6x-3)[/tex]
Operating:
[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]
[tex]A=12x^2-6x+54x-27[/tex]
Simplifying:
[tex]\boxed{A=12x^2+48x-27}[/tex]
