Answer:
the order in which you solve an equation
Step-by-step explanation:
parentheses
exponents
multiply
divide
add
subtract
Answer:
a.
b.
Step-by-step explanation:
We are given that
a.(0,-1)
Differentiate w.r.t x
.....(1)
Substitute x=0 and y=-1 in equation (1)
Point-slope form:
Using the formula
This is required equation of tangent line to the given curve at point (0,-1).
b.(-1/2,1/2)
Substitute the value in equation (1)
Again using point-slope formula
Divide both numbers in one of the ratios by their highest common factor. This will give you the scale factor of the bigger triangle to the smaller triangle.
When you are rounding to a certain place value, first identify the place value you are rounding to by underlining it. The digit to the immediate right of that number will determine whether you add 1 to the underlined digit or it remains the same.
For example....
1. 7.445 rounded to the nearest tenth. Underline the first 4 after the decimal and circle the 4 that is to the right. Answer this question....is the number that is circled 5 or greater? If the answer is YES, add one to the underlined digit. If the answer is NO, leave the underlined number the same and change all remaining digits to the right of it to ZERO. Most of the time, those ZEROs will simply vanish because they are unnecessary.....
7.445 = 7.4 rounded.
2. 7.999 rounded to the nearest tenth. This one is a bit trickier....but you'll still follow the same process. Underline the first 9 next to the decimal and circle the 9 immediately to the right. The answer to the question is yes, so you'll add one to the underlined digit. This will cause it to become a zero and you'll add 1 to your whole number. BUT....keep that 0 there because it's in the tenths place. All of the other digits will vanish.
7.999 = 8.0 rounded.
Follow that same process for the remainder of your questions and you will have mastered the art of ROUNDING!!!!
Hope that's clear and GOOD LUCK!
