What is the explicit formula for this sequence?
2, 10, 50, 250, 1250, ...
O A. an = 2(5)(n-1)
O B. an = 5(2)(n-1)
O C. a, = 2 + (5)"
O D. an = 2(5)"

Answers

Answer 1

Answer:

O D. an = 2(5)"

Step-by-step explanation:

Given the expression/sequence below

2, 10, 50, 250, 1250, ...

O D. an = 2(5)"

The explicit formula is C

a0= 2*5^0= 2

a1=2*5^1= 10

a2= 2*5^2= 50

a3=2*5^3= 250

a4=2*5^4= 1250

Answers

Answer:

326.06 in^3

Step-by-step explanation:

Volume of the cylinder = [tex]\pi[/tex] · [tex]r^{2}[/tex] · h

Volume of the cylinder = [tex]\pi[/tex] · [tex]4^{2}[/tex] · 4

Volume of the cylinder = [tex]\pi[/tex] · 16 · 4

Volume of the cylinder = [tex]\pi[/tex] · 64

Volume of the cylinder = 201.06 in^3

Volume of the composite = length · width · height

Volume of the composite = 5 · 5 · 5

Volume of the composite = 125 in^3

201.06 + 125 = 326.06 in^3

 

The number of views on a viral video can be modeled by the function
G(t)=960(2}^t+1
Write an equivalent function of the form G(t)=ab^t.

Answers

An equivalent function can be written as [tex]G(t) = 1920 \times 2^t[/tex]

What is equivalent fraction?

Fractions that represent the same amount or portion of a whole, but have different denominators and numerators is called Equivalent fractions.

They are equal in value, but may have different forms.

We can multiply or divide both the numerator and the denominator of a fraction by the same number for find equivalent fractions.

Some examples are 2/4 is equivalent to 1/2 because if you divide both the numerator and the denominator of 2/4 by 2, you get 1/2.

Starting from the given function, we can simplify it as

[tex]G(t) = 960(2^t + 1) \\ G(t) = 960 \times 2^t \times 2^1 \\ G(t) = 1920 \times 2^t[/tex]

We can see that this function is of the form

[tex]G(t) = ab^t[/tex]

where a = 1920 and b = 2.

Therefore, an equivalent function can be written as [tex]G(t) = 1920 \times 2^t[/tex]

Step-by-step explanation:

A function shows the relationship between the set of inputs (independent variable) to the set of outputs (dependent variables).

The domain of a function is the set of possible inputs (independent variable) that satisfies the functions.

From the question, the domain of the function is the set of all possible vales of the inputs which is a (number of album sold).

Center is (2,-2) another point on the circle is (-4,6) An equation of the circle in standard form is what?

Answers

Answer:

(x - 2)^2 + (y + 2)^2 = 100

Step-by-step explanation:

We know that the equation for a circle with a center in the point (a, b) and a radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

Here we know that the center of the circle is the point (2, - 2) and that the point (-4, 6) lies on the circle.

Then the radius of this circle will be the distance between (2, - 2) and  (-4, 6)

Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is given by:

[tex]D = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Then the distance between (2, - 2) and  (-4, 6) is:

[tex]D = \sqrt{(2 - (-4))^2 + (-2 - 6)^2} = \sqrt{6^2 + (-8)^2} = \sqrt{100} = 10[/tex]

Then the radius of the circle is R = 10

and we know that the center is (2, -2)

the equation for this circle is then:

(x - 2)^2 + (y - (-2))^2 = 10^2

(x - 2)^2 + (y + 2)^2 = 100

A line passed through the point (8,5) and has a slope of 2. Write an equation for this line

Answers

Answer:

y = 2x -11

Step-by-step explanation:

The equation of  a line that passes through point x1, y1 is given as

y - y1 = m (x - x1)

where m is the slope of the line

Given that the line passes through the point (8,5) and has a slope of 2, the equation of the line

y - 5 = 2 (x - 8)

y - 5 = 2x - 16

add 5 to both sides

y = 2x - 16 + 5

y = 2x -11

[tex]h(x)=2(x + 3)^{\frac{1}{2} }[/tex]

Step-by-step explanation:

Parent function of the square root function has been given as,

f(x) = [tex]x^{\frac{1}{2} }[/tex]

If the graph of the given function is stretched vertically by the scale factor = g(x) = [tex]k(x^\frac{1}{2})[/tex]

If the graph is shifted 3 units to the left,

h(x) = [tex]k(x + 3)^{\frac{1}{2} }[/tex]

Since, the graph of the function passes through a point (-2, 2),

[tex]2=k(-2 + 3)^\frac{1}{2}[/tex]

2 = k

Therefore, the function is [tex]h(x)=2(x + 3)^{\frac{1}{2} }[/tex].

in a class 3/5 of the pupils are boys. If there are 24 girls,how many boys are there in the class ?​

Answer:

36 boys

Step-by-step explanation:

let x be the number of pupils in the class , then

[tex]\frac{3}{5}[/tex] x + 24 = x ( multiply through by 5 to clear the fraction )

3x + 120 = 5x ( subtract 3x from both sides )

120 = 2x ( divide both sides by 2 )

60 = x

Then

number of boys = [tex]\frac{3}{5}[/tex] × 60 = 3 × 12 = 36

Answers

Answer:

9:24 am

Step-by-step explanation:

89 bus = 8 minutes

368 bus = 12 minutes

Find the lowest common multiple(L.C.M) of 8 minutes and 12 minutes

8 minutes = 16, 24, 32, 40, 48

12 minutes = 24, 36, 48, 60

The L.C.M of 8 minutes and 12 minutes is 24 minutes

Both buses are at the same stop at 9 am.

The next time both buses will be at the same stand = 9 am + 24 minutes

= 9:24 am

The 2 given angles are same- side interior angles and sum to 180° , then

7x - 1 + 5x - 23 = 180

12x - 24 = 180 ( add 24 to both sides )
