2l + 2w = P
l = 35, P = 84, w=?
2*35 + 2*w = 84
70 + 2w = 84
2w = 84 - 70
2w = 14
w = 14/2
w = 7 in
Answer:
See the attached figure.
Step-by-step explanation:
Measurements M1 ⇒ x
Measurements M2⇒ y
From the given table the order pairs will be as following:
(0.243,0.245) (0.352,0.348) (0.357,0.361) (0.469,0.470) (0.444,0.439) (0.555,0.560) (0.552,0.548)
The scatter plot for the data will be as shown at the attached figure.
Answer: the third option m(x) = - 7x
Justification:
1) For a function to have inverse function, the original function has to be one to one. This is for the original function two (or more) images cannot have different inputs. That condition is satisfied by the function m(x) = - 7x, since it is a straigh line.
2) the function b (x) = x^2 + 3 is a parabola. That means that, except by the vertex, every image is realated with two inputs.
For example, b(x) = 103 => x^2 = 103 - 3 = 100 => x = 10 and x = -10.
3) For the function d(x) = - 9, you cannot tell the input value for the image because it is the same image for any value of x.
4) The function p(x) = |x| also has a pair of images for the same value of x (excpet for the vertex).
For example, for x = - 100 and x = 100, p(x) = 100, so you cannot tell the x value given the p(x) value.

Answer:
x = 8
Step-by-step explanation:
Taking the antilog, you have ...
3x +8 = 2^5 = 32
3x = 24 . . . . subtract 8
x = 8 . . . . . . .divide by 3
___
You can have a graphing calculator show you the answer. Subtracting 5 from both sides gives ...
log2(3x +8) -5 = 0
The calculator can plot the left-side function and show you the value of x that makes it zero. That value is x=8.
