Answer: it not a function

The domains are :( -6, -4, 3 and 6)

The range are ( 2, 4 and 6)

Step-by-step explanation: to test if it's a function, we will use vertical line test

1) Y = mX + c

M = 0 and

2) y = x^2

The fail both of the two test equation. We therefore conclude that it's not a function it just a mere relation.

The domains are set of X variables

While range are set of Y variables

11 The sides of two similar triangle are in a ratio of 5:6. The area of the larger triangle is 108.
Elodia [21]

Answer:

The area of the smaller triangle is 75.

Step-by-step explanation:

Here, the ratio of the sides of the similar triangle are 5 : 6

The area if the larger triangle = 108

let us assume that the area of the smaller triangle = m

By the Theorem:

In two similar triangles, the ratio of the areas of similar triangles is the square of the ratio of their sides.

Similarly, here

[tex](\frac{5}{6}) ^2  = \frac{m}{108}[/tex]

⇒\frac{(5)^2}{(6)^2}   = \frac{m}{108}

or, \frac{25}{36}   = \frac{m}{108}  \implies m = \frac{108 \times 25}{36}  = 75

⇒ m = 75

Hence, the area of the smaller triangle is 75.

uysha [10]
The picture in the attached figure

we know that
area of rectangle=base*height
in this problem
base is 22 ft
height is 2 yd

convert yd to ft
1 yd is equal to 3 ft
2 yd--------> 2*3-----> 6 ft

area of rectangle=22*6-----> 132 ft²

the answer is
132 ft²

Step-by-step explanation:

it depends if you do 90/100 or 100/90

90/100 = 0.9

100/90 = 1.1(for infinity)

so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
