For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.
(4+8/2)*5-1
first step divide in the parentheses
(4+4)*5-1
second step add in the parentheses
8*5-1
third step multiply
40-1
last step subtract
39
Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
X=-3 and y=1 Hope this helps!
Step-by-step explanation:
We have 6 angles. They are:-
- Accute angle (between 0° and 90°)
- Right angle (exactly 90°)
- Obtuse angle (between 90° and 189°)
- Straight angle (exactly 180°)
- Reflex angle (between 180° and 360°)
- Complete turn (exactly 360°)
