1st Question:
the answer is 85 because the angle measure does not change even if you rotate the figure.
2nd Question:
The answer is A) reflection across y-axis and translation 7 units down
3rd Question:
The first answer choice is correct because the figure increases/decreases in length on all side lengths and the angle measures stay the same.
Question 10: (on the test online)
The answer is 12*6 or 72 because 30 (a'b') / 5 (ab) is 6 giving you the scale factor for the dilation.
Question 11:
The answer is a dilation
Question 12:
The answer is a dilation and a translation because you first increase the size of the figure then move it down and to the right.

Mark dropped an object from a bridge 400 feet above the ground level with an initial velocity of 0. He knows that the gravitatio

lisabon 2012 [21]

Answer:

The first listed equation is the correct equation to solve

The correct answer is: t = 5 seconds

Step-by-step explanation:

Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :

$y(t)=-16\,t^2+ 0 \,t +400$

and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:

$0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0$

which solving for "t" becomes:

$16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec$

So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.

That is: t = 5 seconds

The table below represents the displacement of a bird from its nest as a function of time: time (hours) x displacement from nest

zubka84 [21]

Answer: See each part below.

Part A: The y-intercept is the first value, or 12. That means that they bird is 12 miles from its nest when the time started.

Part B: The average rate of change is the slope. From 1 to 3 hours, the bird went from 20 to 36 or 16 miles. 16 miles in 2 hours is the same as 8 miles in 1 hour.

Part C: To find the extent of the domain, write and solve the following equation for 172 miles.
172 = 8x + 12
160 = 8x
20 = x

The domain will go up to 20 hours.
