what kind of growth model (pattern) is showen in the table x 1, 2, 3, 4, 5 y 5, 25, 125 ,635 ,3,125
Answer:
x= AP, y= GP
Step-by-step explanation:
x = 1, 2, 3, 4, 5 - difference in terms = 1, this is AP
y = 5, 25, 125, 625, 3125 - the ratio of increase= 5, this is GP
Answer:
x= AP, y= GP
Step-by-step explanation:
solve the system of simultaneos equations using substitution method. 2/x-3/x=1 equation one 1/x-2/y= 2. equation two
Answer:
First solve the first one
2/x -3/x = 1
Multiply through by x
2/x×x -3/x×x = x
You will get
2 - 3 = x
x = - 1
Substitute x into the second Equation
1/x - 2/y = 2
x = 1
1/1 -2/y = 2
-2/y = 2-1
-2/y = 1
y = -2
Therefore x = - 1 and y = - 2
Hope this helps.

use factoring to solve
3x^2-11x-6=0
Answer:
x = -0.62 and x = 4.29
These values are approximations !
Step-by-step explanation:
You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?
Anyway, to solve it, you can still use the ABC formula.
3x²-11x-6=0
a = 3
b =-11
c = -6
x = [11 + √{121 -4(3 *-6)} ]/ 2*3
x = [11 + √{121 -4(-24)} ]/ 6
x = [11 + √{121 + 96} ]/ 6
x = [11 + √{217} ]/ 6
x = 4.29 This is an approximation !
x = [11 - √{121 -4(3 *-6)} ]/ 2*3
x = [11 - √{121 -4(-24)} ]/ 6
x = [11 - √{121 + 96} ]/ 6
x = [11 - √{217} ]/ 6
x = -0.62 This is an approximation !

An athletics squad trains on a long straight track with dots marked at 10m intervals. The coach sets out cones on some of the dots for the squad's sprint training drills. She wants the squad to be able to run any distance which is a multiple of 10m, up to some maximum distance which depends on the number of cones.
Explain why it is not possible to place four cones A, B, C, D, in a line so that each multiple of 10m up to 70m can be run between two of the cones.
Answer:
There are 6 ways to run 10 m between two cones of the four cones giving a maximum available distance to run as 60 meters
Step-by-step explanation:
The parameters given are
Distance between two cones = 10 m
Number of cones = 4
Therefore, number of ways to choose two 10 m distances (distance between two cones) from the four cones = [tex]\binom{4}{2}[/tex] = 6
Hence there are only six 10 m distances to run between two cones which gives a maximum distance available to run as 60 m.

pleassseee help me solve 4b+11=39
Answer:
b = 7
Step-by-step explanation:
4b + 11 = 39
Subtract 11 to both sides
4b = 39-11
4b = 28
Dividing both sides by 4
b = 7
!!WILL MARK BRAINLIEST!! Write in slope-intercept form an equation of the line that passes through the given points.
Answer:
y = 1/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (2-1)/(8-4)
= 1/4
The slope intercept form of a line is
y = mx+b
where m is the slope and b is the y intercept
y = 1/4x +b
Substitute a point into the equation
1 = 1/4(4) +b
1 = 1+b
b= 0
y = 1/4x

Answer:
0.15p+3=9
Lyda ordered 40 photos or p=40
Step-by-step explanation:
The formula for this is:
0.15p+3
Where p is the amount of pictures ordered.
0.15p+3=9
Subtract 3 from both sides
0.15p=6
Divide both sides by 0.15
p=40
Lyda ordered 40 photos
Find the missing side. Leave your answer in simplest radical form.

Find the surface area and volume of the prism.
Answer:
SA: 456
V: 408
Step-by-step explanation:
To find the volume of this prism, you first need to find the area of the triangular base. The base has dimensions 6 by 8, and since it's a triangle, the area of the base is 6*8/2=24. Multiplying this by the length of the prism, you get a volume of 24*17=408. For the surface area, you need to find and add together the areas of all of the surfaces. We have already determined that the area of the two triangular bases are 24. The rectangle formed by the leg with length 6 has area 6*17=102, the one with length 8 has area 136, and the hypotenuse has area 170. Adding all of this together, you get a surface area of 24+24+102+136+170=456 square centimeters. Hope this helps!
Formula of surface area: T.S.A = ph + 2b
p: represents the perimeter of the base, h
h: the height of the prism and B
B: the area of the base.
6 + 8 + 10 = 24
24 x 17 = 408cm^2
Formula of Volume:
V: of a prism is the area of the base
B: times the height h
h: height
V=Bh
8 x 7 = 56cm^3
Can someone please help me it’s for geometry thank you :)
Answer:
QST = 2x= 2*20 = 40°
Step-by-step explanation:
RSQ+QST= RST
we know that RST is 124
So,
84+2x= 124
Bringing 84 to the other side it becomes negative
2x= 124-84
= 40
Therefore,
x= 40/2
= 20 °

We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.
[tex]A=\frac{1}{2}absinC[/tex] , where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,
a = 17, b = 15 and C = 35 degrees. Filling in:
[tex]A=\frac{1}{2}(17)(15)sin35[/tex]
Do that on your calculator in degree mode and you'll find the area to be

Answer:
y = 1/4 x -3
Step-by-step explanation:
The y intercept ( or where it crosses the y axis ) is -3
Pick 2 points to find the slope
(0,-3) and (4,-2)
The slope is
m = (y2-y1)/(x2-x1)
= (-2 --3)/ (4-0)
= (-2+3)/4
1/4
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 1/4 x -3

Answer:
C. Both f(x) and its inverse function intersect at point (2, 2).
Step-by-step explanation:
First of all, let's begin defining f(x) = y.
Since the linear function f(x) intersects at
• 6 on the y-axis; and
• 3 on the x-axis;
we can deduce the following equation:
6x + 3y = 6(3)
6x + 3y = 18
3y = -6x + 18
y = -6x/3 + 18/3
y = -2x + 6
f(x) = -2x + 6
Then, we'd want to find the inverse of f(x), which is f`¹(x).
f(x) = -2x + 6
y = -2x + 6
Interchange the variable y to x and vice versa.
x = -2y + 6
2y = -x + 6
y = (-1/2)x + 3
f`¹(x) = (-1/2)x + 3
Since both f(x) and its inverse function are equal to y, set them both as equal.
f(x) = f`¹(x)
-2x + 6 = (-1/2)x + 3
-2x + (1/2)x = 3 - 6
(-3/2)x = -3
x = 2
Substitute x = 2 into y = -2x + 6.
y = -2(2) + 6
y = -4 + 6
y = 2
Now that we know x = 2 and y = 2, then the intersection point of (x, y) must be (2, 2).
I hope this helps! Sorry if my English didn't really help with giving a clearer explanation.

Examine the following gizmo problem and choose the best answer
Answer:
C. The answer is correct
Step-by-step Explanation:
One of the rules that applies when simplifying radical expressions, is that, only like radicals can be added together or subtracted from each other. In other words, the radicand, which is the number inside the "√" must be the same for two or more radicals to be added together or subtracted from each other.
In the expression given in the question, step 1 and step 2 are correct, as well as the final answer.
The final answer is correct because only like radicals can be added as 3√19 and 8√38 are unlike radicals. Their radicands, √19 and √38, are not the same, hence, the radicals do not need to be added.
The answer "3√19 + 8√38" is correct.
