In scientific notation, the number would be 9.3 × 10^-11
Answer:
B) 6.68
Step-by-step explanation:
Use Cosine.
Cosine= Adjacent ÷ Hypotenuse
In this case the base you want to find is adjacent to the angle, 42°. Hence,
Cos (42)= adjacent ÷ hypotenuse
Cos (42) = x ÷ 9
x = Cos (42) × 9. Input that into your calculator.
x= 6.68
To remember the trigonometric ratios/formulas
Use the acronym, SOHCAHTOA
Hope this helps!!!!
Answer:
the second row is not a function! top row is a function
Step-by-step explanation:
because in order for it to be a function for every x there is exactly one y meaning there is no repeating x values! the second row had x = 5 twice, therefore they repeated x values meaning it's not a function
Answer:
There are 10 two point questions and 16 five point questions.
Step-by-step explanation:
- x = the number of 2 points questions
- y = the number of 5 points questions
- x + y = 26
- 2x + 5y = 100
- x = 10 two points questions
- y = 16 five points questions
Subtract k from both sides of problem
X+k-k = w+v-k
X= w+v-k
