Answer: for part b it would be y=x16

Step-by-step explanation:

because theres 16 pencils in one box so to get 32 for the second box you multiply 2 by 16 and so on and so forth

Answer:

16, 32, 48,64,80,96    

1 dime+1penny+1nickel=16 cents, then keep multiplying untill you get more than 100

The possible total amount with Nick if hew has the same number of pennies , nickels and dimes is given by 16 cents , 32 cents , 48 cents , 64 cents , 80 cents , and 96 cents

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

The value of 1 penny be x

So , the value of one nickel = 5x

The value of one dime = 10x

The total value = x + 5x + 10x = 16x

So , the total value should be less than 100 cents or $ 1

Substituting the values in the equation , we get

16x < 100

x < 6

So , the possible combinations are 16 cents , 32 cents , 48 cents , 64 cents , 80 cents , and 96 cents

Hence , the inequality is x < 6

Answer:

The spy plane will re-fuel at coordinates ( 8, 7 )

Step-by-step explanation:

The spy plane leaves a secret runway at A (–16 , 28) and heads toward a missile factory at B.

We have to find Line 1

Runway (-16,28)

-16 = x2

28 = y2

Missile Factory

(48, –28)

48 = x1

-28 = y1

So we set up the equation:

a = y2 - y1 / x2 - x1 = 28 - (-28) / -16 - 48 = 56/-64 = -0.875

Now we must find the equaion: y = ax + b

we substitute a with -0.875

so the new equation will look like this: y = -0.875x + b

y2 = 28 = y

x2 = -16 = x

y = -0.875x + b

28 = -0.875(-16) + b

28 = 14 + b

28 - 14 = 14 - 14 + b

14 = b

so y = -0.875x + 14

Now lets solve for Line 2

we use the same formula:

a = y2 - y1 / x2 - x1 = 37 - (-13) / 56 - (-24) = 50/80 = 0.625

Now we must find the equaion: y = ax + b

we substitute a with 0.625

so the new equation will look like this: y = 0.625x + b

y2 = 37 = y

x2 = 56 = x

y = 0.625x + b

37 = 0.625(56) + b

37 = 35 + b

37 - 35 = 35 - 35 + b

2 = b

so y = 0.625x + 2

Now according to the text, it says "At what coordinates will the two planes meet to re-fuel the spy plane"

which means we have to find the point of intersection, which means we have to make both equation = to each other

so the problem would look like this:

-0.875x + 14 = 0.625x + 2

-0.875 + 0.875x + 14 = 0.625x + 0.875x + 2

14 = 1.5x + 2

14 - 2 = 1.5x + 2 - 2

12 = 1.5x

12/1.5 = 1.5x/1.5

8 = x

now that we know the x, we need to find the y

so y = 0.625x + 2 turns into

y = 0.625(8) + 2

y = 5 + 2

y = 7

so the answer is: The spy plane will re-fuel at coordinates ( 8, 7 )

Answer: A

Step-by-step explanation:

Answer:

It is a right angled triangle.

so

tan32 = p/b

or, tan32 = x/5

or, tan32×5 = x

so, x = 3.124

for 5 no. the answer is a. 3.124

For y,

cos32 = b/h

or, cos32 = 5/y

or, y = 5/cos32

so, y = 5.895

for 6 no. 5.895 is closest to 5.994, so the answer is c. 5.994.

The value of the required function is [tex](3x^{3} + 6x^{2} - x - 2)[/tex].

A function represents the relation between two sets. The first one is called domain and the second one is called range.

Two given functions are:

[tex]f(x) = x + 2 \\g(x) = 3x^{2} - 1[/tex]

Therefore the required function,

The rate of return for the $12,000 investment in one year is 12%.

The correct answer is option C) 12 percent.

The simple interest formula can be expressed as:

Interest = Principal × Rate × Time

Given the parameters:

Principal P = $12,000

Interest I = $1,440

Elapsed time t = 1 year

Interest rate r =?

Plug the given values into the formula above and solve for the interest rate.

Interest = Principal × Rate × Time

1440 = 12000 × Rate × 1

1440 = 12000 × Rate

Rate = 1440 / 12000

Rate = 0.12

Convert to percentage:

Rate = 0.12 × 100%

Rate = 12%

Therefore, the interest rate is 12 percent.

Option C) 12 percent is the correct answer.
