There are 1000 three digit locker combinations are possible if the digits are able to repeat.

The correct option is B.

If the digits are able to repeat, there are 10 options for each digit (0-9) in a three-digit combination.

Since each digit can be chosen independently, the total number of different three-digit combinations is given by:

Number of combinations

= Number of options for the first digit x Number of options for the second digit x Number of options for the third digit

Number of combinations = 10 x 10 x 10 = 1000

Answer:

Therefore, the correct option is: (C.) [tex]\( f(x) = 2 \cdot 4^x \)[/tex]

Explanation:

To determine the exponential function that passes through the given points, we can use the general form of an exponential function:

[tex]\[ f(x) = a \cdot b^x \][/tex]

Where:

[tex]\( a \)[/tex] is the initial value or the value of the function when [tex]\( x = 0 \).[/tex]

[tex]\( b \)[/tex] is the base of the exponential function.

Given the points [tex]\((1, 8)\) and \((4, 512)\)[/tex], we can substitute these coordinates into the general form and solve for [tex]\( a \) and \( b \).[/tex]

Using the point [tex]\((1, 8)\):[/tex]

[tex]\[ 8 = a \cdot b^1 \][/tex]

[tex]\[ 8 = a \cdot b \][/tex]

Using the point [tex]\((4, 512)\):[/tex]

[tex]\[ 512 = a \cdot b^4 \][/tex]

We can divide the equation obtained from the second point by the equation obtained from the first point to eliminate [tex]\( a \)[/tex] and solve for [tex]\( b \):[/tex]

[tex]\[ \frac{512}{8} = \frac{a \cdot b^4}{a \cdot b} \][/tex]

[tex]\[ 64 = b^3 \][/tex]

Taking the cube root of both sides:

[tex]\[ b = 4 \][/tex]

Now that we have found the value of [tex]\( b \)[/tex], we can substitute it back into one of the equations to find \( a \). Let's use the first point [tex]\((1, 8)\):[/tex]

[tex]\[ 8 = a \cdot 4 \][/tex]

[tex]\[ a = 2 \][/tex]

So, the exponential function that passes through the points [tex]\((1, 8)\) and \((4, 512)\)[/tex] is:

[tex]\[ f(x) = 2 \cdot 4^x \][/tex]

To solve the problem:

Let f = distance one way distance on level ground

Let h = distance rode on the hill

Write a time equation; where Time = distance/speed:

level time + uphill time + downhill time + level time = 1hr

f/9 + h/6 + h/18 + f/9 = 1 hr

Multiply equation by 18 to get rid of the denominators

2f + 3h + h + 2f = 18

4f + 4h = 18

Simplify by dividing this by 4

f + h = 4.5 miles is took her to get to Jon’s house.

The expression √(4x^2/3y) simplifies to (2x)/√(3y), by taking the square root of the numerator and the denominator separately.

To simplify the expression √(4x^2/3y), we will start by simplifying the square root of a fraction, which can be done by taking the square root of the numerator and the denominator separately. We have √(4x^2) = 2x because the square root of 4 is 2 and the square root of x^2 is x. For the denominator, we have √(3y), which cannot be simplified further without additional information about y. Therefore, the simplified form of the expression is (2x)/√(3y).

Remember, if we encounter an expression with a higher root like a fourth root, we would raise the number to the 0.25 power, which is equivalent to taking the square root twice. While simplifying expressions, we may also need to solve for variables in an equation or work with fractional powers, which represent roots, such as x^2 = √x.

According to the given rectangle, approximately 112.27 feet of fence are required to enclose the rose garden.

The perimeter of a rectangle is the sum of all its sides. In this case, the rectangle has two sides of length 24 feet and two sides of length 18 feet.

Therefore, the perimeter of the rectangle can be calculated as follows:

Perimeter of rectangle = 2 * (Length + Width)

= 2 * (24 ft + 18 ft) = 2 * 42 ft = 84 ft.

The circumference of a circle can be calculated using the formula:

Circumference = π * Diameter.

Diameter of the Semicircle: The diameter of the semicircle is equal to the width of the rectangle, which is 18 feet.

Circumference of the Semicircle: Using the formula mentioned above:

Circumference = π * 18 ft

≈ 56.5487 ft (rounded to four decimal places).

Perimeter of the Semicircle: As it is a semicircle, we only need half of the circumference:

Perimeter of semicircle = Circumference / 2

≈ 56.5487 ft / 2 ≈ 28.2744 ft (rounded to four decimal places).

Total Fence Length Required: Now, we add the perimeter of the rectangle and the semicircle to find the total length of fence required to enclose the rose garden:

Total fence length = Perimeter of rectangle + Perimeter of semicircle

= 84 ft + 28.2744 ft ≈ 112.2744 ft (rounded to four decimal places).

Answer:

y = 3/7 x - 12/7

Step-by-step explanation:

The slope is (0+3)/(4+3) = 3/7

So, now you have a point and a slope, so use the point-slope form. That gives you

y-0 = 3/7 (x-4)

Now just rearrange to slope-intercept form.

y = 3/7 x - 12/7

The expression 3x + 2 - 3x + 7 +5x simplifies to 5x

when the terms containing variable 'x' are combined. Therefore, the coefficient in the simplified expression is 5.

The given expression is 3x + 2 – 3x + 7 +5x.

To simplify this expression, we need to combine like terms, which in this case are terms with x.

The like terms are 3x, -3x, and 5x. When added together, they simplify to: 3x - 3x + 5x = 5x.

The number part of the term, excluding x, is referred to as the coefficient. So the coefficient of x in this simplified expression is 5.

A right-angled triangle is a triangle with one of its angle 90 degrees and has two adjacent sides and a hypotenuse which is the longest side.

Analysis:

Since it is a right-angled triangle, we use Pythagoras theorem

[tex]hypotenuse^{2}[/tex] = [tex]opposite^{2}[/tex] + [tex]adjacent ^{2}[/tex]

hypotenuse = 20cm, opposite = 12cm, adjacent = xcm

[tex]20^{2}[/tex] = [tex]x^{2}[/tex] + [tex]12^{2}[/tex]

[tex]x^{2}[/tex] = 400 - 144

[tex]x^{2}[/tex] = 256

x = [tex]\sqrt{256}[/tex] = 16cm

The values of k that satisfy the equation 4y'' = -9y for the function y = cos kt are k = ±3/2.

This is a question in differential equations, where we are given a cosine function y = cos kt and asked to find values of k that satisfy the given equation 4y'' = −9y.

Recall, the second derivative of cos kt is -k²cos kt which is equivalent to -k²y.

Substituting that into the differential equation, we get 4(-k²y) = -9y. If we simplify this, we get k² = 9/4. Therefore, the values of k which satisfy the given equation are k = ±3/2.

The values of k that satisfy the differential equation 4y'' = −9y are k = ±3/2.

We can find the values of k that satisfy the differential equation 4y'' = −9y by solving for k.

First, we can rewrite the differential equation in its general form:

ay'' + by' + cy = 0

where a = 4, b = 0, and c = -9.

Next, we can find the characteristic equation:

ar^2 + br + c = 0

Plugging in the values of a, b, and c, we get:

4r^2 + 0r - 9 = 0

Solving for r, we get:

r = ±3/2

Therefore, the general solution to the differential equation is:

y = Acos(3t/2) + Bsin(3t/2)

where A and B are arbitrary constants.

Finally, we can substitute y = cos kt into the original differential equation and solve for k:

4k^2cos kt + 9cos kt = 0

Dividing both sides by cos kt, we get:

4k^2 + 9 = 0

Solving for k, we get:

k = ±3/2
