find the common ratio of the geometric sequence
Answers
Step-by-step explanation:
the formula to find common ratio is
r= second term/first term
The common ratio of the given the geometric sequence is -0.3
What is a geometric sequence?A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Given that, a geometric sequence, is -162,54,-18.6,... we need to find the common ratio,
In a standard geometric sequence, a₁, a₂, a₃, a₄, a₅..... the common ratio is given by :-
a₂ / a₁ = a₃ / a₂ .... = r
Here, r = -54/162 = -18.6/54 = -0.3
Hence, the common ratio of the given the geometric sequence is -0.3

What has to happen for scales to be balanced?
Answers
Answer:
When the pans contain exactly the same mass the beam is in balance. ... You can place an object in one pan and standard weights in the other to find what the object weighs. Here balance scales are used to show that the box "x" has a mass of 4
Answer:
a balances measure mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.

Answer:
8
Step-by-step explanation:
If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:
8 * x / 2 = 32
Now, solve:
[tex]8x/2=32\\4x=32\\x=8[/tex]
Answer:
x=8
Step-by-step explanation:
Area is equal to half of the base times the height. We are told that the area is 32and the base is 8, so we can write this equation:
32=1/2(8)h
Multiply 1/2 by 8:
32=4h
Divide both sides by 4:
h=8
So now we know that x (the height) equals 8.

x = 9
Step-by-step explanation:
Perimeter of rectangle = 2(l+b) = 42
=> 2(x+3 + x)
=> 2 (2x + 3) = 42
=> 4x + 6 = 42
=> 4x = 42 - 6
=> 4x = 36
=> x = 36/4
=> x = 9
Hope it helps :)
Answer:
Formula = (l + b) x 2= 42 so answer = x=9
Step-by-step explanation:
l =x
b =x+3
( x+x+3) * 2 =42
2x +3 x 2 = 42
2x +3 = 42/2
2x +3 = 21
2x = 21 - 3 =18
x = 18/2
x=9

c) [tex]h(t)=-16(t-1.5)^{2}+676[/tex]
Step-by-step explanation:
Each of the given equations is written in vertex form. This means that the vertex is written in the equation. The quadratic term (the term to the second degree), contains (x), and a value that is either added or subtracted to it. The additive inverse (meaning a number times negative one) of that number is the x-coordinate of the vertex. Therefore, the term inside the parenthesis is (-1.5). The constant is the y-coordinate of the vertex, and therefore it is 676. Since the object is being thrown off a cliff, gravity acts on it. The gravitational constant in feet per second is (-16), hence the coefficient of the quadratic term is (-16).

Pls help! I don’t understand!! :/
Answers
Answer:
p=1/5t
Step-by-step explanation:
Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.
Answer:
p = t(0.2)
Step-by-step explanation:
The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.

2.) x - y = 6
2x = 12 + 2y
3.)1/2 x - y = 4
2y = x + 6
Answers
Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28
Cos30=b/28 b=24.25
now 14^2+24.25^2=c^2 which gives 28.00111604 or 28

What is the y=mx+b of the equation 3x−2y=12
Answers
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
Answer:
y=3/2x-6
Step-by-step explanation:
3x-2y=12
isolate the y:
-2y=-3x+12
get rid of the coefficient in front of y by dividing by -2
y=-3/-2x+12/-2
y=3/2x-6

For the 1,000-meter running event, Abby's mean time is 4.5 minutes with a standard deviation of 0.75 minutes. For the 800-meter event, Abby's mean time is 3.2 minutes with a standard deviation of 0.4 minutes. In the last track meet, Abby ran the 1,000-meter race in 4.1 minutes and the 800-meter race in 3 minutes. In which event did Abby have a better performance?
Answers
Answer:
He performed better in the 800 m race
Step-by-step explanation:
Obtain the standardized score for each event :
Zscore = (score - mean) / standard deviation
1000 meter :
Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1
Zscore = (4.1 - 4.5) / 0.75
Zscore = - 0.4 / 0.75 = - 0.5333
800 meter :
Mean = 3.2 ; Standard deviation = 0.4 ; x = 3
Zscore = (3 - 3.2) / 0.4
Zscore = - 0.2 / 0.4 = - 0.5
-0.5 > - 0.533
Hence, he performed better in the 800 m race
Answer:
Abby had a better performance in the 800-meter because this z-score was closer to the mean than the z-score for the 1,000-meter.
