The time required for the baseball to reach the given height is 2 and 5/3 units respectively.

The general form of a quadratic equation is given as ax^2 + bx + c = 0.

Here, a ≠ 0 and b and c are integers.

The degree of a quadratic equation is 2.

The equation for the height of baseball can be written as,

h(t) = -12t² + 44t + 6

It is a quadratic equation.

At h = 46 ft, the value of t can be found as,

Plug h(t) = 46 in  h(t) = -12t² + 44t + 6 as,

⇒ -12t² + 44t + 6 = 46

⇒ -12t² + 44t - 40 = 0

⇒ t = 2, 5/3

Hence, the time at which the height is 46 ft are given as 2 and 5/3 units respectively.

By function composition, f(x) and g(x) are inverse functions

A function is a relationship between inputs where each input is related to exactly one output.

f(x)= ∛(x-1) and g(x)=x³+1

To confirm the inverse relationship using composition.

If f(g(x)) = g(f(x)) then they are inverse functions

Let's confirm:

f(g(x)) = f(∛(x³+1))

         = ( ∛((x³+1)-1 )

        = ∛(x³)

       = x

g(x)=x³+1

g(f(x)) = g(∛(x-1) )

        = (∛(x-1))³ + 1

        = x-1+1

        = x

Since  f(g(x)) = g(f(x)) then they are inverse functions

Events A and B are dependent, because P(A)≠P(B|A). The correct option is A.

From the information, the experiment consists of rolling a standard six-sided die once. Event A is "rolling a 5 and event B is "rolling an odd number."

Events A and B are dependent because the outcome of event A (rolling a 5) affects the probability of event B (rolling an odd number). The probability of rolling a 5 is 1/6, while the probability of rolling an odd number given that you have already rolled a 5 is 0. The probability of rolling an odd number is 1/2, and thus P(A) ≠ P(B|A)

Then he will meet his goal.

Notice that the number 24 is the Less Common Multiple of the numbers 6 and 8: 24 = LCM(6,8).

Answer:

There would be six pieces in each pan.

Step-by-step explanation:

1. To make the number of pieces in each pan equal, the total number must be the same.

2. 8 pieces from the first pan + 6 pieces from the second pan = 14 pieces.

3. Divide 14 by 2 to get the same number of pieces in each pan:

14/2 = 7

The paper company shipped 10 small boxes and 8 large boxes.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of small boxes shipped and y represent the number of large boxes shipped.

Each small box of paper weighs 30 pounds and each large box of paper weighs 75 pounds.

A total of 18 boxes of paper were shipped, hence:

x + y = 18

y = 18 - x    (1)

Also, they weighed 900 pounds, hence:

30x + 75y = 900

but y = 18 - x, hence:

30x + 75(18 - x) = 900

30x - 75x + 1350 = 900

x = 10

y = 18 - x = 18 - 10 = 8

The company had 10 small boxes and 8 large boxes.

The correct expression to represent this situation through inequality is "p + n ≥ 17"

In mathematics, inequalities are mathematical expressions that compare two values without using the symbol = (equal). Instead, in inequalities, one value is greater than, less than, etc. Due to this, the most common symbols used to write an inequality are:

< = This means less than

> = This means greater than

≥ = This means equal or greater than

≤ = This means equal or less than

Considering, the amoung of pennies and nickels is minimum 17, the correct symbol to use is ≥, which means the amoung of coins is either 17 or more than 70. Moreover, the letters p and n can be used to represent the pennies and nickels. Based on this, the correct expression is:

The percentage increase in the cost of the jewelry items that All That Glitters Jewelry Store uses to markup its prices to maximize its profits is as follows:

The percentage increase shows the relative differences between the original cost prices of the pieces of jewelry and their selling prices.

This percentage increase is otherwise known as the markup.

The markup shows the percent increase by which an item is sold to achieve a profit target.

The formula for computing percent increase is the Increase divided by the original amount multiplied by 100.

Answer:

4

Step-by-step explanation:

To find f(-1), we can plug -1 into the equation in place of x and simplify:

f(-1) = 4(-1)² + 9(-1) + 9

f(-1) = 4 + (-9) + 9

f(-1) = 4 - 9 + 9

f(-1) = 4 - 0

f(-1) = 4

Therefore, f(-1) = 4.

The equation representing this relationship is y = 1.5x and the constant of proportionality is 1.5.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s. If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Given that, the amount of flour needed for a recipe is proportional to the number of servings planned.

If a variable x is proportional to the other variable y, then the equation representing the relation is y = kx.

Here y is the amount of flour required and x is the number of servings planned.

When y = 4.5, x = 3.

4.5 = 3k

k = 4.5 / 3 = 1.5

The equation is y = 1.5 x, which represents the relationship between the amount of flour required and the number of servings planned.

Constant of proportionality is 1.5.

This means that the ratio of the y to x is a constant and is equal to 1.5.

Hence the equation representing the situation is y = 1.5x.

Adeniyi   = (2/7)

Akintola  = (4/7)

Bello     =   (1/7)

Step-by-step explanation:

Let x stand for the money that Adeniyi recieves for her share.  We can then write expressions for all the lucky recipients:

Adeniyi = x

Akintola = 2x  [Akintola gets twice as much as Adeniyi]

Bello = (1/2)x  [Bello gets half of Adeniyi's share]

The original amount is the sum of all three shares:

Total = x + 2x + (1/2)x

Total = (3+(1/2))x  or = (7/2)x

The proportions for each can be set as the ratio of the individual's amount to the total of (7/2)x.

Adeniyi = x/((7/2)x)       = (2/7)

Akintola = 2x/((7/2)x)    = (4/7)

Bello = (1/2)x/((7/2)x)    =  (1/7)

Total  =                             (7/7)

What is division?

Division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication, and it is used to find out how many times one number is contained within another number.

To find out how many ounces of chips are in the bag, you can use the formula:

cost of bag / cost per ounce = number of ounces

In this case, you know that the cost of the bag is $3.91 and the cost per ounce of chips is 29.5 cents per ounce.

First, you need to convert the cost per ounce from cents to dollars. 29.5 cents is equal to 0.295 dollars (29.5 cents / 100 cents = 0.295 dollars)

So, you can substitute these values into the formula:

3.91 / 0.295 = 13.38
