Answer:

false

Step-by-step explanation:

The inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element

Housing costs are what percentage of monthly net income? Use the budget sheet to calculate. Round your answer to the nearest who
GenaCL600 [577]
Net income is 1875
 the expenses are listed in the table.
 to find the percentage, divide the cost of the expense by the net income:

housing = 430 / 1875 = 0.229 = 22.9% 
food = 300 / 1875 = 0.16 = 16%
utilities = 125 / 1875 = 0.066 = 6.6% 
transportation = 320 / 1875 = 0.17 = 17%
savings = 500 / 1875 = 0.266 = 26.6 %
other = 200 / 1875 = 0.106 = 10.6%

round the percentages to whole numbers if needed

PLS HELP ME NOW ITS PYTHAGOREAN THEOREM
rusak2 [61]

Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2

(Sinθ-cosθ)(sinθ+cosθ)=1-2cos^2θ
ohaa [14]

Answer:

See below

Step-by-step explanation:

( \sin \theta -  \cos \theta)( \sin \theta  +  \cos \theta) = 1 - 2 { \cos}^{2}  \theta \\  \\ LHS   = ( \sin \theta -  \cos \theta)( \sin \theta  +  \cos \theta)  \\  \\  =  \sin^{2}  \theta -  \cos^{2}  \theta \\  \\  =1 -  \cos^{2}  \theta -  \cos^{2}  \theta \\( \because  \sin^{2}  \theta =1 -  \cos^{2}  \theta)  \\  \\  = 1 - 2 { \cos}^{2}  \theta   \\ = RHS

Thus proved
