Mr. Cohen drives 84 2/10 miles on Tuesday, 84 6/10 on Wednesday, and 85 miles on Thursday. What is the rule of the distance he drives each day? Show how you can check your answer.

Answers

He drives an extra 4/10 miles you can check your work by adding 4

Answer:

He drives an extra 4/10 of a mile every day.

Step-by-step explanation:

Looking at our pattern, we see that to get from 84 2/10 to 84 6/10, we would add 4/10.

Similarly, to get from 84 6/10 to 85, we would add 4/10.

This means we add 4/10 of a mile every day.

To check, we can subtract:

85-84 6/10 = 4/10

84 6/10-84 2/10 = 4/10

A soccer ball is kicked into the air, and its path can be modeled with a quadratic function. The table shows the time, t, in seconds, and the height of the soccer ball, h, in feet. Follow the steps to write the function. 1. Identify x-intercepts: (0, 0) and (5, 0) 2. Use factored form: f(t) = a(t − 0)(t − 5) f(t) = at(t − 5) 3. Find the value of: 12 = a(3)(3 − 5) 4. Write function: f(t) = t(t −)

Answers

The quadratic equation for the soccer ball kicked into the air is,

$f(t) = -2t^2+ 5t$

Given-

Given that t is the time and h is height gain by the ball after kicked.Step 1- Identify x-intercepts at (0,0) and (5,0)

Equation of quadratic function for the given question can be written as,

$y=a(x-h)^2+k$

Step 1- Identify x-intercepts at (0,0) and (5,0)

The intercepts of y are (0,0) and (5,0)

Step 2- The equation of the quadratic function

$f(t)= at (t-5)$

Step 3- Find the value of a for the given function,

$12=a(3)(3-5)$

$12=3a*(-2)$

$a=(12)/(-6)$

Step 4-Function of the equation

Put the value of a in function, we get

$f(t) = -2t(t- 5)$

$f(t) = -2t^2+ 5t$

Hence, the above equation is the required equation for the given problem.

The y-intercepts are
(0,0) and (5,0)
The equation of the quadratic function is
f(t) = at(t-5)
Solving for a
12 = a(3)(3-5)
a = -2
The equation of the quadractic function is
f(t) = -2t(t -5)
f(t) = -2t² + 10t

a pencil sits in a pencil holder that is a rectangular prism. the pencil sits on a diagonal inside the box. find the length of the pencil (the rectangle prism measures 8cm height 4cm length and 3cm width) Pythagorean theorem

Answers

$the\ length\ of\ the\ pencil= the\ length\ of\ the\ diagonal=\n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = √(a^2+b^2+c^2) \n\n√(a^2+b^2+c^2) = √(8^2+4^2+3^2) = √(64+16+9) = √(89)\approx9.43\ [cm] \n\nAns.\ the\ length\ of\ the\ pencil\ is\ about\ 9.43\ [cm]$

Diagonal of rectanglular prism = √a² + b² + c²

= √8² + 4² + 3²

= √89

= 9.43

Thus, the pencil is 9.43 cm long.

which answer describes the number and type of solutions for the given equation? use the discriminant. x^2 + 8x + 10 = 0.

Answers

no real roots. using the equation
$\sqrt{ {8}^(2) - 4(2)(10) }$
when it is less then zero, no real solutions. equ to zero, one real solution. higher then zero, two real solutions.
