Answer:
a. 226 pounds
b. 8 weeks
Step-by-step explanation:
To solve this problem, simply plug in the numbers for the variables it told you they correspond to. 12 is the number of weeks, and t represents the number of weeks, so we can plug 12 in for t.
Simplify and you'll have your answer.
For part B, 234 is the amount of pounds, and W represents the weight in pounds, so we can plug 234 in for W.
Answer: Choice A) -3
Work Shown:
Which leads us to choice A. In the second step, I used the rule that is equivalent to
. For each equation, the b is the base. Note how logs undo exponents and vice versa.
Answer:
x = 10 , y = 10
Step-by-step explanation:
using the sine and cosine ratios in the right triangle and the exact values
cos60° = , sin60° =
, then
cos60° = =
=
( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10
and
sin60° = =
=
( cross- multiply )
2y = 20 ×
= 20
( divide both sides by 2 )
y = 10
