Step-by-step explanation:

Negative 3 using exponents will be negative 3^4

Answer:

3^4, or (-3)^4

Step-by-step explanation:

We are multiplying -3 four times, so

(-3)^4

Since we are multiplying an even amount of times, that equals (3)^4

Answer:

2 minutes

Step-by-step explanation:

9 divided by 18 = 2

2 customers entered the store per minute.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, 9 customers entered a store over the course of 18 minutes.

∴ The rate at which customers entered per minute can be obtained by dividing the total time by the total no. of customers which is,

= (18/9).

= 2 customers per minute.

Answer:

Step-by-step explanation:

Given

Required

Determine the store with the best price per unit

It should be noted that the store with the best has the least price per unit.

So, we have:

Store 1

[tex]Quantity = 10\ ft[/tex]

[tex]Price = \$2.50[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]

Rate = $0.250 per feet

Store 2

[tex]Quantity = 2\ yd[/tex]

[tex]Price = \$1.85[/tex]

Convert quantity to feet

[tex]Quantity = 2 * 3ft = 6ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]

Rate = $0.308 per feet

Store 3

[tex]Quantity = 12\ ft[/tex]

[tex]Price = \$3.40[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]

Rate = $0.283 per feet

Store 4

[tex]Quantity = 5\ yd[/tex]

[tex]Price = \$4.00[/tex]

Convert quantity to feet

[tex]Quantity = 5 * 3ft = 15ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]

Rate = $0.267 per feet

From the calculations above; store 1 has the least unit rate.

Hence, store 1 has the best price per unit

Answer:

Step-by-step explanation:

24 × 1 = 24 = 4

6. 6

i am pretty sure that's it

Answer:

its 4

Step-by-step explanation:

You can think of 24 as 24/1 so

24 X 1/6

and to multiply two fractions you multiply the numerators and denominators so

24 * 1/6

Now you can divide 6 into 24 and get 4.

Answer:

80

Step-by-step explanation:

Answer:

18.75

Step-by-step explanation:

The formula to find the area of a triangle is

A= [tex]\frac{1}{2}[/tex]*b*h

The formula to find the area of a rectangle is simply the length times the base.

Here, you can separate the shapes, two triangle and one rectangle to make it easier to find. Subtract 7.5 and 2.5 to get 5, which will be the base measurements for the triangles.

Next, find the area for the triangles: [tex]\frac{1}{2}[/tex] x 5 x 2.5= 6.25, however, you have two triangles, so multiply by two to get 12.5.

Now, find the area of the rectangle, 2.5 +2.5= 6.25

Lastly, add the measurements together, 12.5 +6.25= 18.75

b^2=81-16

b^2=65

b=√65

√65≈8.06

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

[tex]Side_2 = 74\ in[/tex]

Step-by-step explanation:

Given

[tex]Side_1= 82\ in[/tex]

[tex]Area = 6068\ in^2[/tex]

Required

Determine the length of the other side

For a rectangle:

[tex]Area = Side_1 * Side_2[/tex]

This gives:

[tex]6068\ in^2 = 82\ in * Side_2[/tex]

Divide both sides by 82in

[tex]\frac{6068\ in^2}{82\ in} = \frac{82\ in}{82\ in} * Side_2[/tex]

[tex]\frac{6068\ in^2}{82\ in} = Side_2[/tex]

[tex]Side_2 = \frac{6068\ in^2}{82\ in}[/tex]

[tex]Side_2 = 74\ in[/tex]

Hence, the length of the other side is 74 inches

Answer:

 5 , 7 , 8 represent the side of acute angled triangle

Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that:

Set of numbers.

Now, We use the following result:

When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.

First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.

if sum > Square of last side ⇒ it is Acute Triangle

if sum = Square of last side ⇒ it is Right Triangle

if sum < Square of last side ⇒ it is Obtuse Triangle  

a). 4  , 5 , 7

4² = 16 ,  5² = 25 , 7² = 49

16 + 25 = 41

Hence, 41 < 49

⇒ It is an Obtuse Triangle.

b). 5 , 7 , 8

5² = 25 , 7² = 49 , 8² = 64

25 + 49 = 74

Hence, 74 > 64

⇒ It is an acute Triangle.

c). 6 , 7 , 10

6² = 36 , 7² = 49 , 10² = 100

36 + 49 = 85

Hence, 85 < 100

⇒ It is an Obtuse Triangle.

d). 7 , 9 , 12

7² = 49 , 9² = 81 , 12² = 144

49 + 81 = 130

Hence, 130 < 144

⇒ It is an Obtuse Triangle.

Therefore, Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

Answer and Step-by-step explanation: The definition of polynomial is "poly" meaning many and Nominal, which means terms. So, Polynomial is an expression of constants, variables, exponents that are combined using mathematical operators: addition, subtraction, multiplication and division.

However, there are exceptions:

The degree of a polynomial is the highest exponent of that variable. For example for polynomial [tex]3x^5+6x-5x^{2}[/tex] , the degree is 5.

Polynomials have 3 different types:
