The absolute value just shows how far one is from 0 so I would set it up like this:
|-70| + 13 = 70 + 13 = 83 which is the correct answer.
Answer:
a)
b)
c)
d)
Step-by-step explanation:
We solve this using backward or forward substitution.
a) We have this:
then:
for we have:
from this, we can see that is a solution for this recurrence relation, where . This is:
b) We have with . Then:
but at the same time
we have:
or
by the next:
We can see that the recurrence rule is:
this is
c)Note that:
taking all this we have to:
then:
this is:
d)We take . Then:
replacing we have:
9514 1404 393
Answer:
5°
Step-by-step explanation:
The angle for 12 inches of ramp length and the angle for 12 inches of run are very similar. Both are near 4.8°, so are 5° when rounded.
If we say 12 inches of <em>run</em>, then the tangent relation applies.
Tan = Opposite/Adjacent
tan(α) = (1 in)/(12 in)
α = arctan(1/12) ≈ 4.764°
The maximum angle is about 5°.
Answer:
image
Step-by-step explanation:
In geometric transformation, a figure is mapped to another form another figure. The points in original image are called preimage of the points formed in the transformed figure that is called image.
There are four types of transformations:
translation
reflection
dilation
rotation
In the given case the figure is translated i.e. all the points in the preimage moved with the same distance and direction. As B is preimage of B'
Hence B’ is the image of B!
