Triangle ADC and Triangle BDA are similar. So, we can setup ratios to solve for x.
Similar triangles has corresponding lengths proportional.
From Triangle ADC, CD corresponds to DA, so
From Triangle BDA, AD corresponds to DB.
Now we can write ratios as:
rounding to nearest tenth, 7.7
correct answer is A
I believe the answer is B. 6.9
through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i. when x = 0, y = 3, so the y-intercept is (0, 3).
if graphs are part of the problem statement, share them. .
the answer is the option b
the range is all real numbers
we know that
the absolute value parent function is equal to
see the attached figure to better understand the problem
a. it is v-shaped > is true
b. the range is all real numbers > is not true
because the range is the > [0,∞)
all real numbers greater than or equal to zero
c. it goes through the origin > is true
d. the domain is all real numbers > is true
