Arithmetic, common difference = -10

==========================================

Explanation:

We subtract 10 from each term to get the next one

5-10 = -5

-5-10 = -15

-15-10 = -25

This is the same as adding -10 to each term

5+(-10) = -5

-5+(-10) = -15

-15+(-10) = -25

So this is why the common difference is -10 and the sequence is arithmetic.

Answer:150p + 300 = x

Step-by-step explanation: Cost $450

For making a phone a day

150p + 300 = x

The required expression representing the total cost in dollars of producing p phones in a given day is C = 150P + 300.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Josiah is in the business of manufacturing phones. He pays a cost of $150 per phone produced for materials and labor and also must pay a daily fixed cost of $300 to rent the building and equipment.

Let, p number of phone manufactured in given day,
According to the quesiton,
C = 150P + 300

Thus, the required expression representing the total cost in dollars of producing p phones in a given day is C = 150P + 300.

Answer:

The value of f(1) is greater than value of f(3)

Step-by-step explanation:

We substitute..x = 1..into the given equation....where we say...

; -2(1)^2 + 3(1) + 10 = 11

Then we substitute..x = 3..into the given equation

;-2(3)^2 + 3(3) + 10

;-2(9) + 9 + 10 = 1

If f(1) = 11 and f(3) = 1...then the value of f(1) is greater than the value of f(3)

Step-by-step explanation:

The given function is f(x) = -2x² + 3x + 10. We are asked to find f(1) and f(3).To find f(1), we substitute 1 in the place of x in the given function and evaluate it.

That is,f(1) = -2(1)² + 3(1) + 10= -2 + 3 + 10= 11To find f(3), we substitute 3 in the place of x in the given function and evaluate it.
That is,f(3) = -2(3)² + 3(3) + 10= -18 + 9 + 10= 1We see that f(1) is larger than f(3).

Hence, the correct answer is "The value of f(1) is larger than the value of f(3)."

Step-by-step explanation:

Answer:

member = 15

nonmember = 55

Step-by-step explanation:

m = member, n= nonmember

1m+6n=345

2m + 2n =140 (divide all by 2 )

m + n = 70

m= 70 - n

70-n + 6n =345

70 + 5n = 345

5n = 345-70

5n = 275

n = 275÷5

n = 55

m = 70 - 55 = 15

m=15

Answer:

e=-2

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Here C = 32π , thus

πd = 32π ( divide both sides by π )

d = 32

Thus a coin with diameter 32 mm should fit through a slot of 35 mm

Answer:

Each side is 320 feet

Step-by-step explanation:

1600/5=320 or 320x5=1600

The length of each side of the Pentagon is 329 meters.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The number of sides = 5

The perimeter of all 5 sides = 1600 meters

5Side = 1600

Side = 1600/5

Side = 320 meters

Thus,

The length of each side is 329 meters.
