Answer:
x=-1
Step-by-step explanation:
1/4x+1/2=2/4x+3/4
1/4x+2/4=2/4x+3/4
2/4=(2/4x-1/4x)+3/4
2/4=1/4x+3/4
2/4-3/4=1/4x
-1/4=1/4x
-1=x
x=-1

Given the geometric sequence tn with t1=96 and r=−1/4, find t4.
Give your answer as a fraction, if necessary. Do not include "t4=" in your answer. For example, if you found t4=9, you would enter 9.
Answer:
3/2
Step-by-step explanation:
Given
[tex]t_1 = 96[/tex]
[tex]r = \frac{1}{4}[/tex]
Required
Find t4
The nth term of a geometric sequence is calculated as:
[tex]t_n = t_1 * r^{n-1[/tex]
So:
[tex]t_4 = t_1 * r^{4-1[/tex]
[tex]t_4 = t_1 * r^3[/tex]
This gives:
[tex]t_4 = 96 * \frac{1}{4}^3[/tex]
[tex]t_4 = 96 * \frac{1}{64}[/tex]
Express as a single fraction
[tex]t_4 = \frac{96}{64}[/tex]
[tex]t_4 = \frac{3}{2}[/tex]
Hence, the 4th term is 3/2
which is is the principal value of sin -1 ( 1 )

you have decided to give your best friend a bag of
red and green marbles for his birthday. your friend
likes green marbles better than red ones, so the
bag has twice as many green marbles as red. The
label on the bag says it lcontains a total of 84 marbles.
How many green marbles are in the bag? Write a
System of equations for this problem. Then solve the
problem using any method you like. Be sure to check
your solutions
Answer:
There are 28 red marbles and 56 green marbles in the bag.
Step-by-step explanation:
Let's define:
R = number of red marbles in the bag.
G = number of green marbles in the bag.
We know that:
"There is a total of 84 marbles in the bag"
Then we can write this as:
R + G = 84
"The bag has twice as many green marbles as red marbles"
Then:
G = 2*R
So we have two equations:
R + G = 84
G = 2*R
This is the system of equations we need to solve.
To solve this, we usually start by isolating one of the variables in one of the equations, here we can see that G is already isolated in the second equation, then we can ignore the first step.
Now that we have an isolated variable, we can replace it in the other equation, then we can replace the second equation in the first one to get:
R + G = 84
R + (2*R) = 84
3*R = 84
R = 84/3 = 28
This means that there are 28 red marbles in the bag.
Now we can use the equation:
G = 2*R
To find the number of green marbles, where we need to replace R y 28, then we get:
G = 2*28 = 56
Which means that there are 56 green marbles.

Step-by-step explanation:
2) 85° = (3x - 5)° [Vertically Opposite Angles]
=> 3x - 5 = 85
=> 3x = 85 + 5
=> 3x = 90
[tex] = > x = \frac{90}{3} [/tex]
=> x = 30
Hence,

The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position.
Their altitude is now 285 feet, but there is no record of their starting altitude.
Write and solve an equation to represent this situation and find their starting altitude.
Answer:
Step-by-step explanation:
The required equation is x+295=285 , where x= starting altitude( in feet).
The starting altitude is -11 feet.
Let x be the starting altitude( in feet) .
Given: The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position.
Then, the altitude is now = x+ 296
Since their altitude is now 285 feet.
So the required equation is x+296=285
Subtract 296 from both sides, we get
x= -11

Which of the equations below could be the equation of this parabola?
(0,0)
Vertex
A. y = 1/4x²
B. x = 1/4y²
C. y = -1/4x²
D. x= -1/4y²
Answer:
B. x = 1/4y²
Step-by-step explanation:
The equation of a parabola is x = 1/4y². Therefore, option B is the correct answer.
What is the parabola?A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.
From the graph,
x-intercept(s): (0,0)
y-intercept(s): (0,0)
Vertex is (0, 0)
Directrix, x=-1
Here, the axis of symmetry is y=0
So, the equation is x = 1/4y²
Therefore, option B is the correct answer.
