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.
Answer:
20.9 ft
Step-by-step explanation:
This is a right triangle trigonometry question because N is 90 degrees. MN is adjacent to M and LM is the hypotenuse. Adjacent any hypotenuse use the cosine function.
plug in known values
switch cos(20) and x using the products property
plug into calculator to get 20.9 ft
Answer:
B
Step-by-step explanation:
And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.
It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.
It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.
It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.
And it is B because the numbers maintain a constant difference between each other, which is -3.
By evaluating the function, we conclude that f(10) = -7
<h3>
How to evaluate the function f(x)?</h3>
Here we know that:
g(x) = 2x - 8
And f(x) = 5 - g(x).
Then we can write:
f(x) = 5 - (2x - 8) = 5 - 2x + 8 = -2x + 13
Now we want ot evaluate it in x = 10, this means replace the variable by the number 10.
f(10) = -2*10 + 13 = -20 + 13 = -7
Then, we conclude that f(10) = 7
