Answer:
7.2
Step-by-step explanation:
14 = c
12= b
√(c² - b²)
12 x 12 = 144
14 x 14 = 196
196-144 = 52
√(52) = 7.21110255093
Answer:
x ≈ 7.2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 14²
x² + 144 = 196 ( subtract 144 from both sides )
x² = 52 ( take square root of both sides )
x = [tex]\sqrt{52}[/tex] ≈ 7.2 ( to the nearest tenth )

Answer:
v = [tex]\sqrt{2}[/tex]/2
u = [tex]\sqrt{6}[/tex]/2
Step-by-step explanation:
[tex]\sqrt{2}[/tex] is across from the 60 degree angle so the side across from 30 degrees is half that
the hypotenuse is the product of the side opposite 30 degrees and [tex]\sqrt{3}[/tex]
so:
[tex]\sqrt{3}[/tex] × [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{6}[/tex]/2

Answer:
B
Step-by-step explanation:
The dimensions of A and B are, respectively, (3, 2) and (2, 2). This means the dimensions of the product will be (3, 2), the same as A. This eliminates answer choices A and C immediately.
__
To determine whether the answer is B or D, find a term in which those matrices differ. Then compute that term from A and B.
Here, term (1, 2) is -37 in choice B and -32 in choice D. The actual product term is the dot product of row 1 of A and column 2 of B:
[1, -4]·[7, 11] = (1)(7) +(-4)(11) = 7 -44 = -37 . . . . matches choice B

What is the rate of decay, r (expressed as a decimal), for data best modeled by the exponential function y equals 3.31 left parenthesis 0.87 right parenthesis superscript x baseline?
r = 0.13
r = 0.87
r = 2.88
r = 3.31
Answers
The rate of decay r is -0.139.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The exponential function [tex]y = 3.31(0.87)^x[/tex] can be written in the form
[tex]y = ab^x,[/tex]
where a = 3.31 and b = 0.87.
The formula for the rate of decay for an exponential function in the form
[tex]y = ab^x[/tex]is r = ln(b)
where ln is the natural logarithm.
In this case,
r = ln(0.87) ≈ - 0.139.
Since r represents the rate of decay as a decimal, the answer is r = - 0.139.
Thus,
The rate of decay r is - 0.139.

quadrilateral have the internal degree sum of 360
not 365
Answer:
I'm not sure if you need the value of x or the entire angle measure, so I'll give you both.
x = 19
The angle measure is 46 degrees
Step-by-step explanation:
The sum of a quadrilateral's interior angles is 360 degrees. With that knowledge, we can subtract the angle measures we have from 360. To do that, we must first add 115 + 118 + 81, which equals 314. Now, we do 360 - 314, which gives us the measure of the unknown angle, which is 46 degrees.
Now, we must find x. We write the equation 2x + 8 = 46 since we know what the angle measure is now. Then, we subtract 8 from both sides, which leaves us with 2x=38. Finally, we need to divide 2 on both sides. If your math is correct, you should end up with x = 19. Hope this helps!
