<h3>Answer:</h3>
a) no solutions
b) B = 49.8° or 130.2°
<h3>Explanation:</h3>
a) By the law of sines, ...
... sin(B)/b = sin(A)/a
... sin(B) = b·sin(A)/a = (11/9)·sin(61°) = 1.069 . . . . . not realizable
there is no solution
b) As before, ...
... sin(B) = (28/25)·sin(43°) ≈ 0.763838...
... B = arcsin(0.763838...) ≈ 49.80°
The side length b is longer than the side length a, so there will be two solutions. The other angle for B is the supplement to this one:
... B = 180° -49.8° = 130.2°

Answer:
$989.23
Step-by-step explanation:
The cost will be the product of the area in square feet and the cost per square foot.
The area of a trapezoid is given by the formula ...
... A = (1/2)(b1 +b2)h . . . . . where b1 and b2 are the base lengths, h is the height
Filling in the given information, the area is ...
... A = (1/2)(73 ft +114 ft)(46 ft) = 4301 ft²
Since each square foot costs $0.23, this number of square feet will cost ...
... (4301 ft²)×$0.23/ft² = $989.23
The landscaper will charge $989.23 to put sod on the backyard.
Answer:
Every day, 43% percent of people are added from the total number of people who receive the email
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
P(t) is the total number of people who receive the email
t is the time in days
a is the initial value
r is the rate of change
we have
so
---> initial number of people who receive the email
solve for r
Convert to percentage
so
The daily percent change in the number of people who receive the email. every day is 43%
therefore
Every day, 43% percent of people are added from the total number of people who receive the email
