X=21 and y=14
Here is how I got it I found out the ratio of the sides that measured 18 and 12
the ratio was 3:2 so I divided 27 by 1 1/2 and I got 18 but since the equation for x was x-3 all i had to do was 21-3=18 so x=21 and i did the same thing with Y

How is this equation completed? I cannot find any examples in the book.
djverab [1.8K]

Answer: Option D

t_{max} =19\ s

Step-by-step explanation:

Note that the projectile height as a function of time is given by the quadratic equation

h = -12t ^ 2 + 456t

To find the maximum height of the projectile we must find the maximum value of the quadratic function.

By definition the maximum value of a quadratic equation of the form

at ^ 2 + bt + c is located on the vertex of the parabola:

t_{max}= -\frac{b}{2a}

Where a

In this case the equation is: h = -12t ^ 2 + 456t

Then

a=-12\\b=456\\c=0

So:

t_{max} = -\frac{456}{2*(-12)}

t_{max} =19\ s

A city planner makes a scale drawing of a proposed playground. The length of the actual playground is 78 feet, and the width is
Allushta [10]

Answer:

  B)  6.5 inches by 3.5 inches

Step-by-step explanation:

Multiplying the actual dimensions by the scale gives the scale dimensions:

  (0.5 in)/(6 ft) × {78 ft, 42 ft}

  = {39/6 in, 21/6 in}

  = {6.5 in, 3.5 in}

The size on the scale drawing is 6.5 inches by 3.5 inches.
