Choose the inverse of y=X2-2

Mathematics
2 answers:
hjlf3 years ago
8 0

For this case we must find the inverse of the following function:

y = x ^ 2-2

We exchange the variables:

x = y ^ 2-2

We clear the variable "y":

Adding 2 to both sides we have:

x + 2 = y ^ 2

Applying square root on both sides of the equation:

y = \pm \sqrt {x + 2}

We change y by f ^ {- 1} (x):f ^ {- 1} (x) =\pm \sqrt {x + 2}

Answer:

f ^ {- 1} (x) = \pm\sqrt {x + 2}

Wilfred is feeding his goats. He gives 56% of the bag of feed to the goats in field A and the rest to the goats in field B. If t
krok68 [10]

Answer:

Feeds = 11.76kg

Step-by-step explanation:

Given

Field\ A= 56\%

Field\ B= The\ rest

Bag = 21kg\ feed

Required

Determine how much goats in field A, get.

To do this, we simply multiply the percentage feed received by goats in field A by the actual bags of feeds

i.e.

Feeds = 56\% * 21kg

Convert percentage to decimal

Feeds = 0.56 * 21kg

Feeds = 11.76kg

<em>Hence, goats in field A get 11.76kg of feeds</em>

Help with number 5 thx
Temka [501]

First, we find the area of the circle.

A = pi * r^2

A = pi * (1 cm)^2

A = pi cm^2

The area of the circle is pi cm^2.

The area of the triangle is also pi cm^2.

Now we use the area of a triangle.

A = (1/2)bh

(1/2)bh = A

(1/2)(3 cm)h = pi cm^2

(3 cm)h = 2pi cm^2

h = (2/3)pi cm

The exact height is \dfrac{2\pi}{3} ~cm

If you want an approximate height, then it is 2.09 cm.

What is the total perimeter of the pitch and seating area?
natima [27]
1m = 100 cm

so
40 m = 4,000 cm
25 m = 2,500 cm
10 m = 1,000 cm

perimeter of big rectangle = 2(4,000 + 2000) = 12,000 cm
perimeter of small rectangle on the left: 2(2,500 + 800) = 6,600 cm
perimeter of small rectangle on the right: 2(1,000 + 800) = 3,600 cm
perimeter of circle = πd = 3.141593 x 200 = 628.32 cm

total area of the pitch and seating area :
=  12,000 + 6,600 + 3,600 + 628.32 = 22,828.32<span> cm

answer
</span>22,828.32 cm<span>
