Answer:
not enough information
Step-by-step explanation:
Perpendicular lines intersect at right angles. Since lines c and b are perpendicular, angles 1, 2, 3, and 4 are right angles, and each one measures 90 degrees.
Angle 2 is formed by the intersection of lines a and b. We are not told anything about the intersection of lines a and b, and we are not told anything about the relationship between lines a and c, so we do not have enough information to determine the measure of angle 2.
<span>The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,
We substitute t = 64 in the expression.
</span>A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg
Answer:
13.5
Step-by-step explanation:
Answer:
pm+2=8
Step-by-step explanation:
Given,
m=3
p=3
We know,
pm+2=3(3)+2
=3×3+2
=6+2
=8
