Convert the following in index form of 2: (a) 64 ​

Answer:

16/25 or 0.64

Step-by-step explanation:

First we separate the 5 from 5√x :

4 = 5×√x

Now we divide both sides by 5 :

4/5 = √x

Now we square both sides :

(4/5)² = x

Simplify :

16/25 = x

0.64 = x

The amount in the account after seven years is approximately $4,582.72.

Compounding refers to the process of earning interest not only on the principal amount of an investment but also on the interest that the investment has previously earned.

The continuous compounding formula is given by:

\(A = Pe^{(rt)}\)

where A is the amount in the account, P is the initial principal, e is the base of the natural logarithm (approximately 2.71828), r is the annual interest rate (as a decimal), and t is the time in years.

In this case, we have P = 2700, r = 0.065, and t = 7. Plugging these values into the formula, we get:

\(A = 2700e^{(0.0657)} \\A= $4,582.72\)

Therefore, the amount in the account after seven years is approximately $4,582.72.

Answer:

23

Step-by-step explanation:

Angle x and the two given angles form a triangle. The interior angles of a triangle add up to be 180.

so

\(124 + 33 + x = 180\)

\(157 + x = 180\)

\(x = 23\)

In the parallelogram below, the value of x is \(23^o\) using the angle sum property .

The angle sum property states that:

The sum of all the interior angles of a triangle is \(180^o\).

A  parallelogram is a four sided figure in which opposite sides are equal and parallel.

Given that:

A parallelogram in which the measurement \(124^o\) and \(33^o\) is given.

The parallelogram is divided into two triangles.

The value of x can be calculated as:

\(x+ 33^o + 124^o = 180^o\) (Angle sum property)

\(157^o +x = 180^o\)

    x =\(180^o- 157^o\)

    x = \(23^o\)

Thus, the value of x is \(23^o\).

Answer:

MJK=90

MJL=63

JLK=63

KML=27

MNL=126

Step-by-step explanation:

If this is a perfect rectangle, then I should be correct:

Each angle of a rectangle is 90 degrees, so MJK is 90

Since we know angle KJL is 27, and MJK is 90, just subtract them to get 63.

Angle JLK should be equal to angle MJL so it is also 63

Angle KML should be equal to angle KJL so it would also be 27

And finally, angle JKN should be 27 so 27+27=54. And since all angles of a triangle add up to 180, you can get angle MNL by subtracting 180-54 to get 126 because angle MNL and JNK/KNJ are equal to each other

The integral of G(x, y, z) = y^2 over the sphere x^2 + y^2 + z^2 = 9 is 36π.

To integrate the function over the given surface, we use the surface integral formula. In this case, we need to integrate G(x, y, z) = y^2 over the sphere x^2 + y^2 + z^2 = 9.

We can express the given surface as S: x^2 + y^2 + z^2 = 9. Since the surface is a sphere, we can use spherical coordinates to simplify the integration.

In spherical coordinates, we have x = ρsin(φ)cos(θ), y = ρsin(φ)sin(θ), and z = ρcos(φ), where ρ is the radius of the sphere (ρ = 3) and φ and θ are the spherical coordinates.

Substituting these expressions into G(x, y, z) = y^2, we get G(ρ, φ, θ) = (ρsin(φ)sin(θ))^2 = ρ^2sin^2(φ)sin^2(θ).

To integrate over the sphere, we integrate G(ρ, φ, θ) with respect to the surface element dσ, which is ρ^2sin(φ)dρdφdθ.

The integral becomes ∬S G(x, y, z)dσ = ∫∫∫ ρ^2sin^2(φ)sin^2(θ)ρ^2sin(φ)dρdφdθ.

Simplifying the integral and evaluating it over the appropriate limits, we get the final result: ∬S G(x, y, z)dσ = 36π.

Landon would need to invest approximately $1,150 to reach a future value of $3,250 in 18 years with an interest rate of 6.6% compounded daily.

To determine how much Landon needs to invest, we can use the compound interest formula, which is:

A = P(1 + r/n)^(nt)

where A is the future value of the account, P is the principal amount (the amount Landon needs to invest), r is the interest rate (in decimal form), n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the interest rate is 6.6% or 0.066, the account is compounded daily, so n = 365, and t = 18. We want to find the principal amount, P, that will result in a future value of $3,250.

Substituting these values into the formula, we get:

3,250 = P(1 + 0.066/365)^(365*18)

Simplifying the right-hand side of the equation, we get:

3,250 = P(1.000181)^6,570

Dividing both sides by (1.000181)^6,570, we get:

P = 3,250 / (1.000181)^6,570

Using a calculator, we can evaluate this expression to find that:

P ≈ $1,150.52

Answer:

-1/2 and -1

Step-by-step explanation:

Our system of equations is:

y = 2x²

y = -3x - 1

We can set the y's equal to each other:

y = 2x² = -3x - 1

Now, we have:

2x² = -3x - 1

Move all the terms to one side by adding both sides by 3x and 1:

2x² + 3x + 1 = 0

We must factor this quadratic. Note that the factoring is:

(2x + 1)(x + 1) = 0

Our solutions are now:

2x + 1 = 0           OR           x + 1 = 0

x = -1/2                                x = -1

.

Thus, our solutions are -1/2 and -1.

The equation of the parabola is y = ( 4/3 ) ( x + 1 )² + 4

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

Let the equation of parabola be represented as A

Now , the value of A is

Let the vertex of the parabola be V

Now , the coordinates of P is V ( -1 , 4 )

and , equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

On simplifying , we get

y = a ( x - ( - 1 ) ) + 4

y = a ( x + 1 )² + 4

Now , the point on the parabola is given by P ( 2 , 16 )

On simplifying , we get

when x = 2 and y = 16

16 = a ( 2 + 1 )² + 4

16 = 9a + 4

12 = 9a

a = 4/3

So , the the value of a is 4/3

And , the equation is g ( x ) = ( 4/3 ) ( x + 1 )² + 4

Therefore , the value of g ( x ) is ( 4/3 ) ( x + 1 )² + 4

Hence , the equation of parabola is g ( x ) = ( 4/3 ) ( x + 1 )² + 4
