Rewrite in a form that does not use exponents

Answer:

78.9  degrees to the nearest tenth.

Step-by-step explanation:

This equals the angle whose tangent is 320/62.5 ( opposite side / adjacent side).

The angle of elevation from the coin to the top of the tower

The angle formed by the line of sight and the horizontal plane for an object above the horizontal.

Given that:

The coin  lands 62.5m away from the center of the base of the 320m- high structure.

Height= 320 m

Base= 62.5 m

Now, tan [tex]\theta[/tex] = [tex]\frac{P}{B}[/tex]

                  =[tex]\frac{320}{62.5}[/tex]

                  = 5.12

               [tex]\theta[/tex]= [tex]tan^{-1} (5.12)[/tex]

               [tex]\theta[/tex]= [tex]78.94^{0}[/tex]

The angle of elevation is: 78.94 degrees.

Answer:

3:20

Step-by-step explanation:

The 360 degrees clockwise rotation of the minute hand corresponds to 60 minutes.

The 90 degrees clockwise rotation is one-fourth of the 360 degrees, and hence will corresponds to 15 minutes.

The time is now 3:05.

After 15 minutes the time will be 3:20

Step-by-step explanation:

Using Pascal's triangle, the expansion, although EXTREMELY lengthy, will help you find the 7th term.  I am going to type out the expansion only up til the 7th term (although there are actually 10 terms because we are raised to the power of 9).  If you would like to learn how to use Pascal's Triangle for binomial expansion, you will need to visit a good website that explains it because it's just too difficult to do it via this website.

The expasion is as follows (up to the 7th term):

[tex]1(3c)^{9} +9(3c)^{8}(2d)^{1} +36(3c)^{7}(2d)^{2} +84(3c)^6(2d)^3+126(3c)^5(2d)^4+126(3c)^4(2d)^5+84(3c)^3(2d)^6[/tex]

That last term is the 7th term.  You find out its value by multiplying all the numbers together and adding on the c^3d^6.  Again those come from Pascal's triangle, and it's one of the coolest math things ever.  I encourage you to take the time to explore how it works.

Answer:

  (d)  $1120.70

Step-by-step explanation:

You want the total of deposited checks as shown on the deposit slip.

The total value of checks is shown on the line "Subtotal." This is amount of the deposited checks. The same deposit slip shows a withdrawal of $80 cash, so the net deposit is $80 less than that subtotal.

Vera deposited $1120.70 in checks, choice D.

The correct total amount of all checks Vera deposited is $664.30, and the deposit ticket reflects a subtotal of $1040.70, which includes both checks and cash. Therefore, option (b) $664.30 is the accurate representation of the total amount of all checks.

To determine the total amount of all checks Vera deposited, we need to add the amounts of the individual checks listed on the deposit ticket.

1. Check #184: $138.09

2. Check #308: $312.15

3. Check #298: $214.14

Adding these amounts: $138.09 + $312.15 + $214.14 = $664.38

Therefore, the correct answer is option (b) $664.30. This represents the total amount of all checks Vera deposited. The deposit ticket indicates the subtotal of checks as $1120.70, but this includes the cash amount received as well. To find the total amount of all checks, we subtract the cash amount received, which is $80.00, from the subtotal: $1120.70 - $80.00 = $1040.70.

Problem-solving:

Let us prepare the leading terms, constant terms, and the coefficients of the polynomial are being asked.

[tex]\boxed{ \ 7x^5 + bx^4 + cx^3 + dx^2 + ex + 6 \ }[/tex]

Now we make the first polynomial, for example:

Thus, the result is [tex]\boxed{\boxed{ \ 7x^5 + 3x^4 - 2x^3 + 2x^2 - 5x + 6 \ }}[/tex]

Then we make the second polynomial as an alternative. For example:

Thus, the polynomial is [tex]\boxed{\boxed{ \ 7x^5 - 6x^4 + 4x^2 + 6 \ }}[/tex]

Of course, you can form another polynomial using the procedure above. Try to vary the coefficients.

Notes:

Let us rephrase the following definitions.

For example, consider the polynomial [tex]\boxed{ \ 2x^4 - 3x^2 - 4x - 5 \ }[/tex]

A polynomial is said to be in standard form if the terms are written in descending order of degree. For example:

Keywords: a polynomial of the 5th degree, a leading coefficient of 7, a constant term of 6, a monomial, terms, the leading coefficient, constant, in a standard form, rational function, whole number power, integer

A polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6 could take the form of 'f(x) = 7x^5 + 6'. The other coefficients (b, c, d, e) can be any real numbers, but for simplicity, they can be set to zero in this instance.

The student's question relates to constructing a polynomial of the 5th degree with specific characteristics in the field of Mathematics, specifically in algebra. One can present such a polynomial with the general form:

f(x) = ax^5 + bx^4 + cx^3 + dx^2 + ex + f

Where the leading coefficient a is 7 and the constant term f is 6. In this case, since the only information provided is the leading coefficient and the constant term, and not any constraints on the other coefficients (b, c, d, e), they can be any real numbers, including zero. Thus, one example of a polynomial fitting these constraints is:

f(x) = 7x^5 + 0x^4 + 0x^3 + 0x^2 + 0x + 6

To simplify the algebra and make calculations easier, one can eliminate terms wherever possible, which in this example has been executed by setting the coefficients of x^4, x^3, x^2, and x to zero. After forming any polynomial, it is also important to check the answer to ensure that it matches the given criteria, which in this case it does.

Answer:

A. 5x^2 − 2x − 24 = 0

Step-by-step explanation:

height = 5b-2

b =x

We can rewrite the height as

h = 5x-2

We know the formula for area of a triangle

A = 1/2 bh

A =1/2 x * (5x-2)

Distributing the x

A=    1/2 (5x^2 - 2x)

We know A =12

12 = 1/2 (5x^2 - 2x)

Multiply each side by 2

12*2 = 2*1/2 (5x^2 - 2x)

24 = 5x^2 - 2x

Subtract 24 from each side

24-24 = 5x^2 - 2x-24

0 = 5x^2 - 2x-24

Answer:

The correct answer would be (8,2.40).

Step-by-step explanation:

Option one(-3, -0.9) and two (-2.5, -0.75) Would not be a viable solution because the value of number of days can not be negative and in option one and two, value of days -3 and -2.5 is negative.

Option three(4.5, 1.35) can not be correct because library charges fee for a full day so the number for days would be a whole number. Library would not charge for 4.5 days, they would either charge of 4 days or 5 days because 4.5 is not an whole number.

Option four(8, 2.40) is the correct answer because it satisfies our equation;

Y= 0.30 * X

2.40= 0.30 * 8

2.40 = 2.40

D is the right answer

Answer:

B.The area of the base of the pyramid is 24cm^2.

C.A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.

E.The volume of this pyramid is 72cm3.

Step-by-step explanation:

Area of base of the pyramid = l × w = 4 × 6 = 24 cm^2

Volume of rectangular pyramid = (l × w × h)/3 = (4 × 6 × 9)/3 = 72 cm^3

Volume of rectangular prism = w × h × l = 9 × 4 × 6 = 216 cm^3

So according to these calculations, the correct answer options are:

B.The area of the base of the pyramid is 24cm^2.

C.A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.

E.The volume of this pyramid is 72cm3.

Final answer:

The true statements about the rectangular pyramid are B, C, and E.

The base area is 24 cm² (Statement B), the volume of the pyramid is 72 cm³ (Statement E), and the volume of a similarly dimensioned rectangular prism is three times that of the pyramid (Statement C).

Explanation:

To determine which statements are true about the rectangular pyramid with given dimensions, we need to calculate the base area and the volume of both the pyramid and the rectangular prism and compare them.

The base area of the pyramid, denoted as B, is the area of the rectangle formed by the base's dimensions.

Therefore, B = length x width = 4 cm x 6 cm = 24 cm².

Thus, statement B is true.

For the volume of the pyramid (V), we use the formula V = (1/3) x B x height.

Plugging the values, we get V = (1/3) x 24 cm² x 9 cm, which equals 72 cm³.

So, statement E is true.

The volume of a rectangular prism with the same height and base dimensions is volume of the prism = length x width x height = 4 cm x 6 cm x 9 cm = 216 cm³.

Since the volume of the prism is three times the volume of the pyramid, statement C is true.

Statements A, D, and F are not true based on the above calculations and explanations.
