Determine the number of solutions: 6x-2=x+13
Finger [1]
Answer: B) one solution

Reason: if we solve for the sides of the equation by putting like terms together we get that x = 3

There is no solution when the numbers don’t equal each other, take for instance 1 = 2

It has infinite solutions when the numbers are equal to each other like
1 = 1

It has one solution when the x value is equal to something like x = 9

I also worked out the equation on paper, so you could get a more visual way of how I solved it.

Hope this helps

How many circles with a 3ft radius could fill a 100 square foot (10ft x 10ft) space without overlap?
Alborosie

Answer:

1

Step-by-step explanation:

Considering that the circle has radius of 3ft to mean its diameter is twice the radius hence 6 ft

Given that the length of the square is 10 ft

10÷6=1 ⅔ hence only 1 circle

10-6=4 ft

The space of 4ft can't allow another circle to fit without an overlap. Therefore, only one circle can fit

Geometric sequence or whatever
sladkih [1.3K]

Step-by-step explanation:

An = -2 * An-1

What this means is that you multiply -2 to the term to get the next term.

Since our 1st term (A1) is -2, we have:

A2 = -2 * A1 = -2 * (-2) = 4,

A3 = -2 * A2 = -2 * (4) = -8,

A4 = -2 * A3 = -2 * (-8) = 16,

A5 = -2 * A4 = -2 * (16) = -32,

A6 = -2 * A5 = -2 * (-32) = 64.

Hence our first 6 terms in the GP are

-2, 4, -8, 16, -32 and 64.

Find all solutions to 2sin(θ)=√3 on the interval 0≤θ<2π
makkiz [27]

Answer:

2sin(3θ) - √3 = 0

Step-by-step explanation:

 sin(3θ) = √3/2

 

3θ = π/3 + 2kπ or 2π/3 + 2kπ, k = 0, ±1, ±2, ±3,...

 

θ = π/9 + 2kπ/3, 2π/9 + 2kπ/3

 

If k = 0, we get θ = π/9, 2π/9

If k = 1, we get θ = 7π/9, 8π/9

If k = 2, we get θ = 13π/9, 14π/9

 

Other values of k give values of θ lying outside of the interval [0, 2π).
