The temperature went down by 12 degrees. (Or you could say it changed by -12 degrees)
Answer:
9.3 repeating
Step-by-step explanation:
Answer:
(a)
(b)
(c)Using Linear Approximation,L(4.2)=137.6
Using Quadratic Approximation,
Step-by-step explanation:
Given:
(a)Linear Approximation,
(b)Quadratic Approximation,
(c)To approximate:
L(x)=48x-64
L(4.2)=48(4.2)-64=137.6
Also, Using Quadratic Approximation
1) 3 groups
2) Animals that fly
3) 32 (? It’s blurry but the answer is the percentage in the blue part)
4) A cow would be classified in “animals that walk” and a whale would be classified in “animals that swim”
5) It would not be useful now because animals like frogs can do multiple things, in early stages it could swim but when it gets older it could live on land. (Sorry if 5 is not the best answer, but it’s how I’d answer it.)
Answer:
see explanation
Step-by-step explanation:
Given A = 3x² + 2y + 2 and B = 6x² - 8y + 1 , then
A + B
= 3x² + 2y + 2 + 6x² - 8y + 1 ← collect like terms
= 9x² - 6y + 3
-------------------------------
A - B
= 3x² + 2y + 2 - (6x² - 8y + 1) ← distribute parenthesis by - 1
= 3x² + 2y + 2 - 6x² + 8y - 1 ← collect like terms
= - 3x² + 10y + 1
