$120 I believe is your answer 1200×.02==24×5=120
Answer:
x = 11.1
Step-by-step explanation:
Cosine theta = adjacent/hypotenuse
cos 42 = x/15
x = 15 cos 42
x = 11.1
Multiplying by 10 can be thought of as just adding a 0 to the right end of a number. If you have 2 and multiply it by 10, you get 20. For 1,234, you get 12,340. If you have 98,765, you can 987,650. Same thing applies for 100, 1000, 10000, ...., and so on. It moves it over depending on the number of 0's there are in the number. If it is 100, it will move two 0's over. For example, if you multiply 45 by 100, you get 4,500. The two zeros from 100 moved to the right side of the 45 to get 4500.
Hello :
f(x) = x²+10x+12
f(x) = (x²+2(5)x+5²)-5² +12
f(x) = (x+5)²-13
<span>the x-intercepts solutions f(x) = 0
(x+5)² -13 =0
(x+5)² =(</span><span>√13)²
x+5 =</span>√13 or x+5 = -√13
x= √13 -5 or x= -√13 -5
