Answer:
11 m/s
Step-by-step explanation:
Using v = u + at
where
v = final velocity which we want to find out
u = 3
a = 2
t = 4
v=u+at
v = 3 + 2×4
v =11 m/s
10b+13 would be the answer
Answer:
<em>The measure of angle A is 73°</em>
Step-by-step explanation:
<u>Isosceles Triangles</u>
An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.
The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.
The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:

Thus:

The measure of angle A is 73°
Answer:
about 5.9%
Step-by-step explanation:
We assume that the original amount of Pb-210 present at death decays at the given rate. The fraction (f) remaining is multiplied by 1/2 every 22 years, so can be modeled by ...
f = (1/2)^(t/22) . . . . . where t is in years after death
Then, for t=90, the remaining fraction is ...
f = (1/2)^(90/22) ≈ 0.05868 ≈ 5.9%
X would be 45 degrees because we know that 45+x=90 degrees. You can tell because when both angles are put together, they make a 90 degrees angle. So, we subtract 45 from 90 to get 45 due to you needing to isolate x. Thus, the answer is 45 degrees. If you can, please mark me as brainliest.
