Figure 1:

Area: 30m^2

Perimeter: 23.6m

Figure 2:

Area: 98.8km^2

Perimeter:56.5km

Step-by-step explanation:

Area is base x height.

To get the perimeter, add up all the sides.

Figure 1:

Area:

6x5=30m^2

Perimeter: 6+5.8+6+5.8=23.6m

Figure 2:

Area:

7.6x13 = 98.8km^2

Perimeter:7.6+15+20+13.9=56.5km

NemiM [27]

Answer:

The probability that the next spin will land on blue is 0.12.

Step-by-step explanation:

The result of the several spins are as follows:

Color Frequency

Red 18

Blue 9

Green 18

Yellow 19

Purple 12

TOTAL 76

Compute the probability that the next spin will land on blue as follows:

$P(Blue)=\frac{n(Blue)}{N}\\\\=\frac{9}{76}\\\\=0.1184211\\\\\approx 0.12$

Thus, the probability that the next spin will land on blue is 0.12.

If f(x) = 5x – 1, then f^-1(x)=

Umnica [9.8K]

Answer:

$\boxed{\sf \ \ \ f^{-1}(x)=\dfrac{x+1}{5} \ \ \ }$

Step-by-step explanation:

hello

f(x)=5x-1

what can we say about $f^{-1}(x) ?$

$(fof^{-1})(x)=x=f(f^{-1}(x))=5f^{-1}(x)-1$

so

$5f^{-1}(x)-1=x\\ 5f^{-1}(x)-1+1=5f^{-1}(x)=x+1 \ \ \ add \ \ 1\\ f^{-1}(x)=\dfrac{x+1}{5} \ \ \ divide \ \ by \ \ 5$

hope this helps
