(3,1) is the corect answer
Answer:
Step-by-step explanation:
tan7=h/820
h=820tan7
h=101m
Answer:
16 ft/s²
Step-by-step explanation:
s(t) = sin(t) - 4cos(2t)
Differentiation for v
v(t) = cos(t) + 8sin(2t)
Differentiate for a
a(t) = -sin(t) + 16cos(2t)
At t = π
a(π) = -sin(π) + 16cos(2π)
= 0 + 16
= 16

You have the correct answer. It is choice B. Nice work.</h3>
K is the midpoint, so
and
, and along with the congruent vertical angles (
and
), you would use the SAS (side angle side) congruence theorem to prove the inner pairs of triangles to be congruent.
So,
(top and bottom triangles) and
(left and right triangles).
Then through CPCTC, we can show the corresponding pieces are congruent leading to
and
showing the opposite sides of the quadrilateral are congruent. Therefore we do have a parallelogram and enough information to prove it as such.
Side note: CPCTC stands for "corresponding parts of congruent triangles are congruent".
First, determine what 15% of $40 is.
Convert 15% to a decimal: 0.15
Then multiply this decimal by $40: 0.15 x 40 = 6
So the discount is $6.
We subtract the discount from original price to get sale price.
40-6= 34
So the item will cost $34.
