The height of the baseball is 6 feet at the moment the player begins to leap. Then the correct option is D.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The first equation in the system models the height in feet, h, of a falling baseball as a function of time, t. the second equation models the height in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

h(t) = 35 - 16t²

h(t) = 6 + 18t + 16t²

At t = 0, Then we have

h(0) = 35 - 16(0)²

h(0) = 35

And

h(0) = 6 + 18(0) + 16(0)²

h(0) = 6

The height of the baseball is 6 feet at the moment the player begins to leap.

More about the function link is given below.

A square is changed into a new rectangle by increasing its width by 2 inches and decreasing its length by 2
solniwko [45]

Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.

Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;

Area = L x W

The length and the width both measure 8 inches (all sides of a square are equal in length).

Area = 8 x 8

Area = 64

Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;

Area = L x W

Area = 10 x 6

Area = 60

Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.

Write the following sentence using mathematical symbols. The product of 9 and x is less than or equal to -37
Kaylis [27]

Answer:

  9x ≤ -37

Step-by-step explanation:

A product of a constant and a variable is indicted by writing the constant next to (typically, in front of) the variable. The symbol ≤ means "is less than or equal to". So ...

  (the product of 9 and x) (is less than or equal to) -37

  9x ≤ -37

The useful life of a certain piece of equipment is determined by the following formula: u=(8d)/h^2, where u is the useful life o
Anni [7]

Answer:

The correct answer is E.

Step-by-step explanation:

First I look for the relationships between the coefficients. The first term corresponds to the base value.

\frac{8*d}{h^{2}}  = \frac{8}{1} * \frac{d}{h^{2} }

The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.

\frac{2*8*d}{(0,5*h)^{2}}  = \frac{16*d}{0,25 * h^{2}}  = \frac{16}{0,25} * \frac{d}{h^{2} }

With the I get the ratio of coefficients of \frac{d}{h^{2}} :

\frac{8}{1} = 8

\frac{16}{0,25} = 64

Now I calculate  the percentage increase in the useful life of the equipment as:

% = \frac{64}{8} * %100 = %800
