Chloe is 200 miles from Los Angeles and she at a constant speed of 55 miles. You just do 200/55 and that’s how long Chloe drives in a hour.
Answer:
B. The limits Lim x-->7 (x²-9x+14)/x-7 and lim x--> 7 (x-2) equals the same number when evaluated using direct substitution. The limit of both functions is 5
Step-by-step explanation:
Find the complete question in the attachment.
Given the limit of the functions
Lim x-->7 (x²-9x+14)/x-7
To solve this, we will need to factorize the quadratic function at the numerator first.
x²-9x+14
= x²-2x-7x+14
= x(x-2)-7(x-2)
= (x-7)(x-2)
The expression therefore becomes:
= lim x-->7 (x-7)(x-2)/x-7
= lim x-->7 (x-2)
Now substitute the value of x into the simplified function
lim x-->7 (x-2) = 7-2
lim x-->7 (x-2) = 5
Hence Lim x-->7 (x²-9x+14)/x-7 = 5
From the calculation above, it can be seen that Lim x-->7 (x²-9x+14)/x-7 = lim x--> 7 (x-2) = 5
Hence the correct answer based on the explanation above is B.
The limits Lim x-->7 (x²-9x+14)/x-7 and lim x--> 7 (x-2) equals the same number when evaluated using direct substitution.
The answer is B (-8,6) this is because the magnitude is 2 so each tiny square is going to increase or decrease by intervals of 2 so if you count by two to the left you get 8 but since its going to the left that will be -8x and now you need to count up by 2's and that equals to 6y and you are at A on the graph so the answer will be (-8,6)
A) because the decimal is repeating, 625.49 is irrational.
B) because 625.89 can be written as the ratio of two integers, 62589 and 100000, this is a rational number.
C) sqrt(90) can be factored: sqrt(9)*sqrt(10). sqrt(9) = 3 (rational), but sqrt(10) is irrational. Thus sqrt(90) is irrational.
D) You try this one yourself, OK?
