A. What restriction is there on the value under the square root symbol? In other words, what can't you
do with a square root expression? (1 point)

Answer:

$800,500 (nearest dollar)

Step-by-step explanation:

The given scenario can be modeled as an exponential equation.

General form of an exponential function:

 \(f(x)=ab^x\)

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

The initial value (a) is the value of the investment.

Therefore, a = 1,000,000.

If the investment decreases by 2.2% each year, then it will be 97.8% of the previous year.

Therefore, b = 97.8% = 0.978.

Substitute these values into the formula to create a general equation for the scenario:

\(f(x)=1000000(0.978)^x\)

(where x is the time, in years).

To find the value of the investment after 10 years, substitute x = 10 into the formula:

\(\implies f(10)=1000000(0.978)^{10}=800500.1586\)

Therefore, the value of the investment after 10 years is $800,500 (nearest dollar).

We need to add 10 students to the hostel so that the food is enough for only 45 days.

Let's assume that "x" students need to be added to the hostel so that the food is enough for only 45 days.

We know that the total amount of food available is fixed, so the product of the number of students and the number of days that the food will last must also be fixed.

We can use this fact to set up an equation:

50 × 54 = (50 + x) × 45

To solve for x, we can simplify and solve for x:

Expand using FOIL method

50 × 54 = (50 + x)45

50 × 54 = 45 × 50 + 45 × x

2700 = 2250 + 45x

450 = 45x

x = 10

Therefore, number of students to be added is 10.

Answer:

steps below

Step-by-step explanation:

AB = DC, AE=DE, ∠BAE = ∠CDE = 90°

ΔBAE ≅ ΔCDE   (SAS)

BE = CE   .. corresponding sides of congruent triangles

∠EBC = ∠ECB  ... base angles of isosceles triangle

∠ABC = ∠ABE + ∠EBC = ∠DCE + ∠ECB = ∠DCB

∠ABC + ∠DCB = 360° - ∠CDE - ∠BAE = 360° - 180° = 180°

∠ABC = ∠ DCB = 1/2 * 180° = 90°

∴ ABCD is rectangle

If 1472cm² of wrapping paper is needed to cover the smaller box, approximately 1672cm² of wrapping paper is needed to cover the larger box (assuming the surface area is directly proportional to the length).

Since the smaller and larger boxes have exactly the same shape, we can assume that their dimensions are proportional.

Let's denote the width and height of the smaller box as "w" and "h," respectively, and the width and height of the larger box as "W" and "H," respectively.

We know that the length of the smaller box is 16 cm, so we have:

Length of smaller box = 16 cm

Width of smaller box = w

Height of smaller box = h

To find the dimensions of the larger box, we can set up a proportion based on the lengths of the boxes:

16 cm / 18 cm = w / W

From this proportion, we can solve for W:

\(W = (18 cm \times w) / 16 cm\)

Now, let's consider the surface area of the boxes.

The surface area of a box is given by the sum of the areas of its six faces. Since the boxes have the same shape, the ratio of their surface areas will be equal to the square of the ratio of their lengths:

Surface area of smaller box / Surface area of larger box = (16 cm / 18 cm)^2.

We know that the surface area of the smaller box is 1472 cm^2, so we can set up the equation:

\(1472 cm^2\) / Surface area of larger box \(= (16 cm / 18 cm)^2\)

To find the surface area of the larger box, we rearrange the equation:

\(Surface $area of larger box = 1472 cm^2 / [(16 cm / 18 cm)^2]\)

Now we can substitute the value of W into the equation to find the surface area of the larger box:

Surface area of larger box \(= 1472 cm^2 / [(16 cm / 18 cm)^2] = 1472 cm^2 / [(18 cm \times w / 16 cm)^2]\)

\(= 1472 cm^2 / [(18 \times w / 16)^2] = 1472 cm^2 / [(9w / 8)^2]\)

\(= 1472 cm^2 / [(81w^2 / 64)]\)

Simplifying further:

Surface area of larger box \(= (1472 cm^2 \times 64) / (81w^2)\)

So the amount of wrapping paper needed to cover the larger box is given by the surface area of the larger box, which is:

\((1472 cm^2 \times 64) / (81w^2)\)

Note that we don't have enough information to calculate the exact value of the wrapping paper needed to cover the larger box since we don't know the width "w" of the smaller box.

Step-by-step explanation:

Power rule of exponents says that the power of the power of a exponent is equal to the multiplying both the powers. The expression which is equal to the given expression is,

\(\dfrac{1}{(r)^{42}} \)

The option B is the correct option.

Given information-

The given expression in the problem is,

\([(r)^{-7}]^5\)

Power rule of exponents says that the power of the power of a exponent is equal to the multiplying both the powers.

Suppose x is a number with power a. The power is power of the power of number x. Then by the power rule of the exponents,

\((x^a)^b=x^{ab}\)

Using the power rule of the exponents given expression can be written as,

\([(r)^{-7}]^6=(r)^{-7\times 6} \)

\([(r)^{-7}]^6=(r)^{-42}\)

Negative exponents rule says that when a power of a number is negative, then write the number in the denominator with the same power with positive sign.Thus,

\([(r)^{-7}]^6=\dfrac{1}{(r)^{42}} \)

Hence the expression which is equal to the given expression is,

\(\dfrac{1}{(r)^{42}} \)

The option B is the correct option.

What is Distributive Law?

The distributive property is the most commonly used property of the number system.

Distributive law is the one which explains how two operations work when performed together on a set of numbers. This law tells us how to multiply an addition of two or more numbers.

Here the two operations are addition and multiplication. The distributive law can be applied to any two operations as long as one is distributive over the other.

This means that the distributive law holds for the arithmetic operations of addition and multiplication over any set.

For example, the distributive law of multiplication over addition is expressed as a(b+c)=ab+ac,

Without using a calculator, the trigonometric expressions simplify to:

1. sin^(-1)(sin(θ/6)) = θ/6

2. cos^(-1)(cos(5/4)) = 5/4

3. tan^(-1)(tan(5/6)) = 5/6.

To compute the trigonometric expressions without using a calculator, we can make use of the properties and relationships between trigonometric functions.

1. sin^(-1)(sin(θ/6)):

Since sin^(-1)(sin(x)) = x for -π/2 ≤ x ≤ π/2, we have sin^(-1)(sin(θ/6)) = θ/6.

2. cos^(-1)(cos(5/4)):

Similarly, cos^(-1)(cos(x)) = x for 0 ≤ x ≤ π. Therefore, cos^(-1)(cos(5/4)) = 5/4.

3. tan^(-1)(tan(5/6)):

tan^(-1)(tan(x)) = x for -π/2 < x < π/2. Thus, tan^(-1)(tan(5/6)) = 5/6.

Hence, without using a calculator, we find that:

sin^(-1)(sin(θ/6)) = θ/6,

cos^(-1)(cos(5/4)) = 5/4,

tan^(-1)(tan(5/6)) = 5/6.

Answer:

x^2-3

Step-by-step explanation:

The location of the vertical asymptote is x = -5, and there is no hole in the function.

A hole on a graph of a rational function is a place where the function is undefinable but may be made continuous by eliminating shared elements in the numerator and denominator. To put it another way, a hole happens when a rational function's numerator and denominator share a component that can be eliminated, yielding a simpler function with no discontinuity at that point.

The given factor is x - 1 / x² + 4x - 5.

Factoring the denominator we have:

x² + 4x - 5 = (x - 1)(x + 5)

The function can be written as:

f(x) = (x - 1) / [(x - 1)(x + 5)]

f(x) = 1 / (x + 5)

The vertical asymptote is at the point x = -5.

There is no hole in the function.

Hence, the location of the vertical asymptote is x = -5, and there is no hole in the function.
