Answer:

increases

decreases but stays above 0.

Step-by-step explanation:

Increases without bound. You are going left which means that x is getting smaller and smaller (large negatives are very small).

As x increases without bounds, f(x) approaches 0 but does not go minus.

Trigonometry

xxMikexx [17]

Answer:

1.309 rad

Step-by-step explanation:

We are told to convert 75° to radians.

# we know that 1° is equivalent to 0.01745radians.

-To convert any angle degree to radians, we multiply it by π/180 or 0.01745rad:

$=75\textdegree \times \pi/180\\\\=1.309 \ rad$

Hence, the radian equivalent of 75 is 1.309 rad

Calculate AD and hence BD.

Vilka [71]

Answer:

AD = 15 cm , BD = 3 cm

Step-by-step explanation:

Δ ABC is similar to Δ ADE ( by the AA postulate )

then the ratios of corresponding sides are in proportion, that is

$\frac{AD}{AB}$ = $\frac{DE}{BC}$ ( substitute values )

$\frac{AD}{12}$ = $\frac{10}{8}$ ( cross- multiply )

8 × AD = 12 × 10 = 120 ( divide both sides by 8 )

AD = 15 cm

AB + BD = AD , that is

12 + BD = 15 ( subtract 12 from both sides )

BD = 3 cm

Find the inverse of the functipn <br><br> f(x)=3x-7/2

vivado [14]

Answer:

2x+7/6

Step-by-step explanation:

an normal function would be mapping x to y, since this is the inverse we would map y to x

f(x) and y are the same so I will take f(x) as "y"

1)3x-7/2=y

3y-7/2=x

solve/isolate "y" in 3y-7/2=x to get the value of "y"

3y-7/2=x

add "7/2" to both sides

3y-7/2+7/2=x+7/2

3y=x+7/2

divide both sides by "3"

3y/3=x/3+7/2/3

simplify:

y=2x+7/6

hope this helps!
