The range is the set of all values of a function will return as outputs.
Answer:D
 The range is the complete set of all possible resulting values of the dependent variable (Y): minimum y-value to maximum y-value.
The domain on the other hand is is the complete set of possible values of the independent variable.

likoan [24]

Answer:

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of an house on a scale drawing in square inches

y ---> the actual area of the house in square feet

$z^2=\frac{x}{y}$

we have

$x=25\ in^2$

$y=2,025\ ft^2$

substitute

$z^2=\frac{25}{2,025}$

simplify

$z^2=\frac{1}{81}$

square root both sides

$z=\frac{1}{9}\ \frac{in}{ft}$

therefore

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Does anyone seriously know how to do these

mr Goodwill [35]

Thats simple!
h(x)= $\frac{x^{2}+3x }{4x+27}$
find h(-8)
All we need to do is PLUG IN THE -8
h(-8)= $\frac{(-8)^{2}+3(-8) }{4(-8)+27}$
= $\frac{64-24}{-32+27}$ (negative²=positive, negative×positive=negative)
= $\frac{40}{-5}$
h(-8)=-8

Here is rectangle A. Block A. Rectangle B is ¹/₅ longer than A Block B. Rectangle C is ¹/₃ longer than B Block C. The total leng

Hoochie [10]

Answer:

Rectangle C is 14 cm longer than B

Step-by-step explanation:

Let x be the length of Rectangle A. Rectangle B is ¹/₅ longer than A Block B,

Therefore the length of rectangle B is:

$x+\frac{1}{5}x$

Rectangle C is ¹/₃ longer than B, therefore the length of rectangle c is:

$x+\frac{1}{5}x+\frac{1}{3}(x+\frac{1}{5}x) =x+ \frac{1}{5}x+\frac{1}{3}x+\frac{1}{15}x=x+\frac{9}{15}x$

The total length of all three rectangles is 133 cm.

Length of rectangle A + Length of rectangle B + Length of rectangle C = 133 cm

$x+x+\frac{1}{5}x +x+\frac{9}{15}x=133\\x+x+x+\frac{1}{5}x +\frac{9}{15}x=133\\3x+\frac{12}{15}x=133\\ 45x+12x=1995\\57x=1995\\x=35cm$

Therefore the length of rectangle A is 35 cm, the length of rectangle B is $35+\frac{1}{5}*35=42\ cm$ and the length of rectangle C is $35+\frac{9}{15}*35=56\ cm$
