Answer:

  • 2 seconds
  • 72 feet

Step-by-step explanation:

The usual equation used for the vertical component of ballistic motion is ...

  h(t) = -16t² +v₀t +h₀

where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.

Your problem statement gives ...

  v₀ = 64 ft/s

  h₀ = 8 ft

so the equation of height is ...

  h(t) = -16t² +64t +8

__

For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...

  t = -64/(2(-16)) = 2

The object will reach its maximum height after 2 seconds.

The height at that time will be ...

  h(2) = -16(2²) +64(2) +8 = 72

The maximum height will be 72 feet.

Help please! I just need to know how to do this step by step...
Alex787 [66]

-8 - 5n = 64 + 3n

    +5n          +5n           add 5n to both sides, 5n's cancel out on the left.

______________

-8 = 64 + 8n

-64 -64                          subtract 64 on both sides, 64's cancel out on the right.

______________

-72 = 8n

___  ___                       divide 8 on both sides, 8's cancel out from the right.

 8      8

What is 1/4 as a whole number?
wlad13 [49]

The whole number of \dfrac{1}{4} is \boxed{0.25}.

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is \dfrac{1}{4}.

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is \dfrac{1}{4}.

Consider the number \dfrac{1}{4} as \text{A}.

A = \dfrac{1}{4}

Divide 1 by 4 to obtain the whole of \dfrac{1}{4}.

\begin{aligned}\text{A}&= \frac{1}{4}\\&= 0.25\\\end{aligned}

The decimal expansion of \dfrac{1}{4} is 0.25.

The whole number of \dfrac{1}{4} is \boxed{0.25}.

SOLUTION

TO DETERMINE

The degree of the polynomial

CONCEPT TO BE IMPLEMENTED

POLYNOMIAL

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

DEGREE OF A POLYNOMIAL

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

EVALUATION

Here the given polynomial is

In the above polynomial variable is z

The highest power of its variable ( z ) that appears with nonzero coefficient is 5

Hence the degree of the polynomial is 5

FINAL ANSWER

The degree of the polynomial is 5
