This is what exponential growth is
Answer:
49x²-16 = (7x - 4)(7x + 4)
Step-by-step explanation:
Your "49×2-16" is incorrect; did you mean "49x^2-16" or "49x²-16?"
This last expression is the difference of two squares.
The formula for that is a² - b² = (a - b)(a + b), and so your 49x²-16 factors as follows:
49x²-16 = (7x - 4)(7x + 4)
Answer:
-8, 16, -32, 64
Step-by-step explanation:
a1 = -8
r = -2
a2 = -8(-2)=16
a3 = -8(-2)²=-8(4)=-32
a4=-8(-2)³=-8(-8)=64
Part A:
Area of a circle is pi*radius^2
a=3.14*1^2
a=3.14
Part B:
Area of a rectangle is length*width
a=5*7
a=35
Part C:
Area of the shaded part would be the area of the rectangle - the area of the circle
a=35-3.14
a=31.86
Answer:
The selling price of house is approximately 270.4264 thousand dollars.
Step-by-step explanation:
We are given the following in the question:
A linear model gives the relation between natural logarithm of price, in thousands of dollars, and size, in 100 square feet.
Let p be the price and s be the size.
We have to approximate the selling price for a house with a size of 3,200 square feet.
Thus, we put s = 32
Thus, the selling price of house is approximately 270.4264 thousand dollars.
