of total sales in a day

putting value in equation



Hence the total number of car washes sold that day are 
J= obtuse
K=right
L=acute
M=acute
First you must change 3/8 into a decimal, so the number would be 45.375. To find scientific notation you have to move the decimal between a factor of 1-10. 4.5375 . You moved over the decimal once toward the left. so scientific notation would be 4.5375 X 10^1
Answer:
A
Step-by-step explanation:
The projection of vector B on unit vector a is
(B•a)a
av(unit vector of v)= 1/√2(-1,1)
u•av= 1/√2 × (-5+7)= √2
(u•av)av= √2 × 1/√2(-1,1)= (-1,1)
Answer:
the correct answer is -5 since y=7
