Answer:
a =5.3
Step-by-step explanation:
The Pythagorean theorem is
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 6^2 = 8^2
a^2 +36 = 64
Subtract 36 from each side
a^2 +36-36 = 64-36
a^2 =28
Take the square root of each side
sqrt(a^2) = sqrt(28)
a = 5.291502622
To the nearest tenth
a =5.3
Answer:
x= -2
Step-by-step explanation:
3(x-6) + (4x+12) -6x
3x -18 + -24x - 72
-3x. -3x
-18 = -27x -72
+72. +72
54=-27x
x= -2

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.
