The 17th term of the given geometric sequence, 3, 12, 48, 192, . . . , is 1.288490189 x 10^10.

A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a ratio.

a(n) = a r^(n-1)

Where:

a(n) = nth term

r = ratio

Given the geometric sequence 3, 12, 48, 192, . . .

Find the ratio,

r = a(n)/a(n-1)

r = a(2)/a(1)

r = 12/3

r = 4

Notice that the ratio between two succeeding terms is always 4.

Use the formula to find the 17th term of the geometric sequence.

a(n) = a r^(n-1)

a(17) = 3[4^(17-1)]

a(17) = 3(4^16)

a(17) = 1.288490189 x 10^10

Answer:

9x^2 + 21x + 12

Step-by-step explanation:

(3x+4)(x+2x+3)

Combine x and 2x to get 3x.

(3x+4)(3x+3)

Apply the distributive property by multiplying each term of 3x+4 by each term of 3x+3.

9x^2 + 9x + 12x + 12

Combine 9x and 12x to get 21x.

9x^2 + 21x + 12

Determine the coordinates of two locations along the line that you choose. Find the difference between these two locations' y-coordinates (rise). Find the difference between these two locations' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.

Formula to determine the slope is - y₂ - y₁ / x₂ - x₁

Given are the points -

(2,4) and (4,2)

Answer:

c) 388 minutes

Step-by-step explanation:

Given equation,

→ C = 29.95 + 0.035x

Then the call duration will be,

→ C = 29.95 + 0.035x

→ 43.53 = 29.95 + 0.035x

→ 0.035x = 43.53 - 29.95

→ x = 13.58/0.035

→ [ x = 388 ]

Hence, option (c) is correct.

The equivalent expression to the given one is  x^8/(9*y^10)

So the correct option is B.

Here we just need to operate with the exponent properties that we know and love.

Remember that:

(a^n)^m = a^(n*m)

Then if we apply that to our case we will get:

(3x^−4y^5) ^−2 = (3^(-2)*x^(-4*-2)*y^(5*-2))

                         = (3^(-2)*x^8*y^(-10)

Now remember that negative exponents just "move" the number to the denominator position, this means that:

3^-2 = 1/3^2 = 1/9

Then we can rewrite our expression as:

(3^(-2)*x^8*y^(-10) = x^8/(9*y^10)

That is the equivalent expression to the given one.

The correct option is B.

Answer:

12

Step-by-step explanation:

the distance would be 12 because if you see the y values they are both -4 so they dont have any distance between them. Now if u look in the x values you will see different values -5 and 7 what u have to do now is do the equation 7 - - 5 which will be 12 because minus and minus will be plus so 7 plus 5 is 12, the distance between those points is 12.

The life of the battery is about 36.5 years, if it requires 35 watts.

A logarithmic term is a number expressed in logarithmic form. Some other name for it is a log term.

Consider some formulas used in log.

Now, as per the given question,

The function is written as;

P = 42e∧(-0.005t).

The value of the power P is mentioned in the question; (P = 35 watt).

Thus, substitute the value of the P in teh equation;

35 = 42e∧(-0.005t).

Now, divide both sides by 42.

0.8333 = e∧(-0.005t)

Taking natural log on both side;

㏒0.8333 = ㏒e∧(-0.005t)

㏒0.8333 = -0.005t

Solve the value of the log by using calculator,

-0.182 = -0.005t

t = 36.5

Therefore, the the life for which the battery will run is 36.5 years.

The triangle formed by joining the midpoint of an isosceles triangle is also an isosceles triangle.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

An isosceles triangle XYZ is been made as shown below. Now, for the ΔXYZ, the midpoints of the line segment XY, YZ, and ZX are A, B, and C, respectively.

Further, the length of the sides of the ΔABC can be written as,

AB = √[(x₂-x₁)² + (y₂-y₁)² ]

     = √[(3 - 1)² + (1 - 1)²]

     = √4

     = 2

BC = √[(x₂-x₁)² + (y₂-y₁)² ]

     = √[(3 - 2)² + (1 - 0)²]

     = √2

AC = √[(x₂-x₁)² + (y₂-y₁)² ]

     = √[(1 - 2)² + (1 - 0)²]

     = √2

Since, the length of the two sides is the same, while the length of the third side is different, thus, the triangle formed by joining the midpoint of an isosceles triangle is also an isosceles triangle.

The equation that is parallel to 4x- 2y = 6 and passes through (0, 1) is y = 2x + 1

The given parameters are

4x - 2y = 6

Divide through by 2

So, we have

2x - y = 3

Make y the subject of formula

So, we have

y = 2x + 3

A linear equation is represented as

y = mx + c

Where

Slope = m

This means that

m = 2

Parallel lines have equal slopes

So, the slope of the other line is

m = 2

The point on the line is given as (0, 1)

The equation is then calculated as

y = m(x- x1) + y1

So, we have

y = 2(x - 0) + 1

Evaluate

y = 2x + 1

Hence, the equation that is parallel to 4x- 2y = 6 and passes through (0, 1) is y = 2x + 1

The center and radius of the circle given by the equation x^2 + y^2 - 4y - 16 = 0 is (0 , 2) and 2√5, respectively.

The standard form of the equation of circle is given by

(x - h)^2 + (y - k)^2 = r^2

where (h , k) is the location of the center and r is the radius of the circle.

On the other hand, the general form of the equation of  circle is given by

x^2 + y^2 + Dx + Ey + F = 0

where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.

If the equation of the circle in general form is x^2 + y^2 - 4y - 16 = 0, then the coefficients are:

D = 0

E = -4

F = -16

If D = -2h and D = 0, then

0 = -2h

h = 0

If E = -2k and E = -4, then

-4 = -2k

k = 2

If F = h^2 + k^2 -r^2 and F = -16, then

-16 = 0^2 + 2^2 - r^2

r^2 = 0 + 4 + 16

r^2 = 20

r = 2√5

=96

The estimated number of times the dice will land on a three in 120 throws is 96 times.

We have,

To estimate the number of times the biased dice will land on a three, we can use the probability of getting a three in a single throw and multiply it by the total number of throws.

Probability of landing on a three in a single throw = 0.8

Total number of throws = 120

Estimated number of times the dice will land on a three

= Probability of landing on a three × Total number of throws

Estimated number of times = 0.8 × 120

Estimated number of times = 96

So, based on the biased dice with a probability of 0.8 for landing on a three, the estimated number of times the dice will land on a three in 120 throws is 96 times.

Thus,

The estimated number of times the dice will land on a three in 120 throws is 96 times.
