Answer:

Step-by-step explanation:

PART A: No, the trinomial 4x^3 + 28x + 49 is not a perfect square trinomial. To be a perfect square trinomial, the first and last terms must be perfect squares and the middle term must be twice the product of the square roots of the first and last terms. In this case, the first and last terms are not perfect squares, and the middle term is not twice the product of the square roots of the first and last terms.

PART B: To factor the expression 6x^2 + 5x - 4, we need to find two binomials whose product is equal to this expression.

First, we can break down the coefficient of x into two numbers whose product is 6 * (-4) = -24 and whose sum is 5. These numbers are 8 and -3.

Next, we use these two numbers to split the middle term 5x into two terms:

6x^2 + 8x - 3x - 4

We can now factor the expression by grouping:

(6x^2 + 8x) - (3x + 4)

2x(3x + 4) - 1(3x + 4)

(2x - 1)(3x + 4)

Therefore, the area of the rectangle can be factored as (2x - 1)(3x + 4).

To determine the dimensions of the rectangle, we set each factor equal to one of the dimensions and solve for the other dimension:

2x - 1 = length

3x + 4 = width

Alternatively, we could switch the factors and get the same answer:

2x - 1 = width

3x + 4 = length

Either way, these are the dimensions of the rectangle, expressed in terms of x.

Answer:

Therefore, you will need to order approximately 9.07 cubic yards of topsoil to fill the garden to a depth of 6 inches.

Step-by-step explanation:

To calculate the amount of topsoil needed, we need to find the volume of the garden in cubic yards, since topsoil is sold by the cubic yard.

The garden is 35 feet by 14 feet and 6 inches (or 0.5 feet) deep.

Volume of the garden = length x width x depth

= 35 feet x 14 feet x 0.5 feet

= 245 cubic feet

To convert cubic feet to cubic yards, we divide by 27 (since 1 cubic yard = 27 cubic feet):

Volume in cubic yards = 245 cubic feet / 27

= 9.07 cubic yards (rounded to two decimal places)

Therefore, you will need to order approximately 9.07 cubic yards of topsoil to fill the garden to a depth of 6 inches.

1. The algae blooms was larger initially is the first algae.

2. The first algae bloom is decreasing more quickly than the second algae bloom.

1. To determine which algae bloom was larger initially, we can compare the values of the functions at d=0.

For the first algae bloom, we have A(0) = 200.

For the second algae bloom, we have B(0) = 100*27⁰ = 100.

Therefore, the first algae bloom was larger initially.

2. To determine which algae bloom is decreasing more quickly, we can compare the rates of decrease of the two functions. The rate of decrease is given by the derivative of the function, which tells us how fast the area is changing with respect to time.

For the first algae bloom, we have A'(t) = -20e^(-0.2t).

For the second algae bloom, we have B'(d) = -100*27^(-1)d.

To compare these rates of decrease, we can evaluate them at the same point in time or days. Let's evaluate them at d=1, which means one day has passed since the first measurement.

For the first algae bloom, we have A'(1) = -20e^(-0.2) ≈ -15.24.

For the second algae bloom, we have B'(1) = -100*27^(-1) ≈ -3.70.

Therefore, we can see that the first algae bloom is decreasing more quickly than the second algae bloom. This is because the rate of decrease of the first bloom is more negative than the rate of decrease of the second bloom.

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

To figure out what fraction of the toys are blue, we need to convert all of the fractions to have a common denominator.

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

Looking at the fractions, we can see that there are 3 fractions, [tex]\frac{1}{8}, \frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex].

To solve for the common denominator between [tex]\frac{1}{8}[/tex] and [tex]\frac{3}{5}[/tex], we first multiply the denominators, 8 and 5.

We now know that the denominator is going to be 40.

To get the numerators, we can use these equations:

The new fractions look like this:

To easily convert the last fraction ([tex]\frac{1}{4}[/tex]) we can multiply the numerator and denominator by 10.

We multiply by 10 because the denominator, which is 4, can be multiplied by 10 to get our common denominator of 40.

Now, we have our 3 fractions converted to have common denominators.

([tex]\frac{5}{40}, \frac{24}{40}[/tex] and [tex]\frac{10}{40}[/tex])

(Yellow, red, and green)

We can now add these up and see what fraction of blue is remaining.

Therefore, the fraction of blue toys compared to the total amount is [tex]\frac{1}{40}[/tex].

If there are 100 green toys resulting in [tex]\frac{10}{40}[/tex] of all the toys, we can divide 100 by 10 to get the number of blue toys.

We divide by 10 because [tex]\frac{1}{40}[/tex] is only [tex]\frac{1}{10}[/tex] of [tex]\frac{10}{40}[/tex], meaning we divide by 10.

Therefore, there are 10 blue toys.

Answer:

1/4=100

10/40=100

40/40=400

1/8=400/8=50

finance charge Jack will​ pay is $1,512.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, Jack Fitzgerald wishes to purchase a used car that has a cash price of ​$11,000. The installment terms include a down payment of ​$2,000 and 48 monthly payments of ​$219.

a)

The amount that needs to be financed is = 11,000 - 2,000 = $9,000.

Amount repayment = 219 x 48 = $8,100.

=> Finance charge = Amount repayment - Amount needs to be financed

Finance charge = 10512 - 9000

Finance charge = 1,512$

b)

We apply the PV for annuity formula to find the interest rate per one month denoted as i:

Amount needs to be finance = (equal monthly installment x i) / [ 1 - (1+i)^-36 ]

or 9,000 = (219/i) x [1 - (1+i)^-48 ] <=> i = 0.911%.

APR = 12 x i

APR = 10.932% .

where x is the number of months it will take for both Thomas and Christian to have the same amount of money in their accounts.

Simplifying this equation, we get:

64x = 44

Dividing both sides by 64, we get:

x = 0.6875

So it will take approximately 0.6875 months for Thomas and Christian to have the same amount of money in their accounts. However, since time is measured in months, we cannot have a fraction of a month. Therefore, we round up the result to the nearest whole month and conclude that it will take 1 month for both Thomas and Christian to have the same amount of money in their accounts.

Answer:

3.2 × 10⁻⁸

Step-by-step explanation:

Scientific notation is written in the form [tex]a \times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one non-zero digit to the left of the decimal point.

The number of times you have moved the decimal point is the power of 10 (the value of n).

Therefore, to convert 0.000000032 to scientific notation, move the decimal point 8 places to the right so that [tex]a[/tex] is 3.2.

As the decimal point has been moved 8 places the right, the exponent of 10 is -8.

Therefore,  0.000000032 = 3.2 × 10⁻⁸.

For the function y=f(x), the domain is (-2,2] and the range is (-2,3).

The corresponding values are -

f(-1) = -6, f(0) = -5, f(1) = 6, f(2) = 3.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The graph for function y = f(x) is given.

The collection of input or argument values for which a function is actual and defined is known as its domain.

In the graph it can be seen that the graph is intersecting x-axis at x = -2 and at x = 2.

So, the domain is (-2,2]. The ( symbol denotes empty circle whereas the ] symbol denotes a filled circle.

A function's range is the collection of values for which the dependent variable is defined.

The coordinates for the ending of the graph is (2,3). So, the range of the function is [-2,3].

The value for f(-1) as seen in the graph is -

x = -1, then y = -6.

The value for f(0) as seen in the graph is -

x = 0, then y = -5.

The value for f(0) as seen in the graph is -

x = 1, then y = 6.

The value for f(2) as seen in the graph is -

x = 2, then y = 3.

Therefore, the domain and range is (-2,2] and (-2,3) respectively.
