Answer:

y = 100x + 400

Step-by-step explanation:

What we know:

     - You started with 400

     - You get 100 a week

What we need to find out:

 - The equation or rate to know how much money acquired in specific time

Step 1 ( of 1 ): Equation

-   if you let y represent the total of money you acquire then the equations starts as

y=

-  Then we know that we get 100 a week so let x represent the amount of weeks so

y = 100x

-  Lastly we know that we started with 400 so then we just add that to the equation to make it

y = 100x + 400

The division equation is x * 3/8 = 5/4 and there are (10/3) times 3/8s there in 5/4.

Let's assume that x times 3/8 are in 5/4.

So, calculating a division equation for the value of x.

x * 3/8 = 5/4

=> x = 5/4 * 8/3

=> x = 40/12

Dividing the numerator and denominator by 4.

We get, the value of x equal to

=> x = 10/3

The equation in terms of log(x) and log(z) is, [tex]logx\sqrt{z} = logx + \frac{1}{2} log(z)[/tex].

What is logarithmic expression?

A logarithmic equation is one in which a variable-containing expression's logarithm is used as a solution. If you can write both sides of the equation as powers of the same number, that will help you answer exponential equations.

Consider, the given logarithmic expression,

[tex]logx\sqrt{z}[/tex]

By using the logarithmic rule: log(ab) = log(a) + log(b)

So,

[tex]logx\sqrt{z} = log(x) + log\sqrt{z}[/tex]           ..(1)

Replace [tex]\sqrt{z}[/tex] by [tex]z^\frac{1}{2}[/tex].

So,

[tex]log\sqrt{z} = logz^\frac{1}{2}[/tex]

Apply the rule: [tex]loga^b = b log(a)[/tex]

Therefore, [tex]log(\sqrt{z}) = \frac{1}{2}log(z)[/tex]

Substitute this value in equation (1).

[tex]logx\sqrt{z} = logx + \frac{1}{2} log(z)[/tex].

Hence, the expression in terms of x and z is, [tex]logx\sqrt{z} = logx + \frac{1}{2} log(z)[/tex].

Answer:

The coordinates of B are (4, 2)

Step-by-step explanation:

The coordinates of B can be calculated as follows ?

The midpoint of line AB is M(3,-3)  is derived from the formula

[tex]M=(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})[/tex]

Where [tex]x_1[/tex] and [tex]y_1[/tex] are the coordinates of A and [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are the coordinates of B

Since the coordinates of A are (2, -8), then the value of [tex]x_1[/tex] is 2 and the value of [tex]y_{1}[/tex] is -8.

Since the [tex]x[/tex]-coordinate of M is 3, then the equation to follow is

[tex]\frac{x_{1}+x_{2}}{2}=3[/tex]

Substitute 2 for [tex]x_{1}[/tex], then it follows that

[tex]\frac{2+x_{2}}{2}=3[/tex]

Multiply both sides of the equation by 2

[tex]\frac{2+x_{2}}{2}\times 2=3\times 2[/tex]

Simplify both sides of the equation

[tex]2+x_{2}=6[/tex]

Substract 2 from both sides of the equation

[tex]2-2+x_{2}=6-2[/tex]

Simplify the equation

[tex]x_{2}=4[/tex]

Since the [tex]y[/tex]-coordinate of M is -3, then the equation to follow is

[tex]\frac{y_{1}+y_{2}}{2}=-3[/tex]

Substitute -8 for [tex]y_{1}[/tex], then it follows that

[tex]\frac{-8+y_{2}}{2}=3[/tex]

Multiply both sides of the equation by 2

[tex]\frac{-8+y_{2}}{2}\times 2=-3\times 2[/tex]

Simplify both sides of the equation

[tex]-8+y_{2}=-6[/tex]

Add 8 to both sides

[tex]-8+8+y_{2}=-6+8[/tex]

Simplify the equation

[tex]y_{2}=2[/tex]

Since the value of [tex]x_{2}[/tex] is 4 and the value of [tex]y_{2}[/tex] is 2, then the coordinates of B are (4,2).

Step-by-step explanation:

You want the height of a model water tower with a volume of 0.1 liters that models a city water tower 40 m high with a volume of 100,000 liters.

The scale factor for volume is the cube of the scale factor for linear dimensions, such as height. Conversely, the scale factor for height is the cube root of the scale factor for volume.

This lets us write a proportion for the height of the model tower:

  [tex]\dfrac{h}{40\text{ m}}=\sqrt[3]{\dfrac{0.1\text{ L}}{100000\text{ L}}}\\\\h=(40\text{ m})\sqrt[3]{10^{-6}}=\boxed{0.40\text{ m}}[/tex]

The area of trapezoid ABCD is 37.5 units^2.

Trapezoid is a type of quadrilateral with at least one pair of parallel sides. The area of trapezoid is given by:

Area = ½(a + b)*h

Where a and b are the length of two parallel sides and h is the perpendicular length between the length of two parallel sides.

In the given trapezoid ABCD, which is defined by coordinates of A, B, C, and D, the distance of each side is given by: √((x2 – x1)^2 + (y2 – y1)^2)

The length of a (DA) = √((x2 – x1)^2 + (y2 – y1)^2) = √((-3 – 0)^2 + (2 – (-2))^2) = √((-3)^2 + (4)^2) = √(9 + 16) = √25 = 5 units

The length of b (BC) = √((x2 – x1)^2 + (y2 – y1)^2) = √((7 – 1)^2 + (-3 – 5)^2) = √((6)^2 + (-8)^2) = √(36 + 64) = √(36 + 64) = √(100) = 10 units

The length of h (AB) = √((x2 – x1)^2 + (y2 – y1)^2) = √((1 – (-3))^2 + (5 – 2)^2) = √((4)^2 + (3)^2) = √(16 + 9) = √(25) = 5 units

Hence, the area of trapezoid:

Area = ½ (5 + 10) * 5 = 7.5 * 5 = 37.5 units^2

Step-by-step explanation:

From the given numbers nickels and quarters ,total value of given coins is less than $2.50 then maximum number of quarters to meet the given condition is equal to 3.

As given in the question,

Let x represents the number of nickels

And y represents the number of quarters

Total number of nickels and quarters are 35

Total value of given coins = $2.50

Required equation for the given condition is:

x + y = 35   ___(1)

1 nickel = 0.05 dollars

1 quarter = 0.25 dollars

0.05x + 0.25y <2.50 ___(2)

Substitute x = 35 - y in (2) we get,

0.05 ( 35 - y ) + 0.25y < 2.50

⇒1.75 - 0.05y + 0.25y < 2.50

⇒ 0.2y < 2.50 - 1.75

⇒ 0.2y < 0.75

⇒ y < 3.75

Maximum number of quarters for the given condition is equal to 3.

Therefore, for the given numbers nickels and quarters ,total value of given coins is less than $2.50 then maximum number of quarters to meet the given condition is equal to 3.

According to the question,

We have the following information:

Each person performed for the same amount of time. Kira sang three solos and played a piano piece. Hector sang 2 solos and played a piano piece that lasted twice as long as Kira's. Each of the solos Kira and Hector sang was 3.5 minutes long.

Now, let's take time for solos to be x min and time for Kira's piano to be y min and that for Hector is z min.

So, we have the following equations:

Kira:

3x+y

Hector:

2x+z

Now, z = 2y

x = 3.5 minutes

Time is equal:

3x+y = 2x+z

3x+y = 2x+2y

3x-2x = 2y-y

x = y

y = 3.5 min

z = 2*3.5

z = 7 min

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

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

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product
