Mathematics
1 answer:
Leto [7]3 years ago
5 0

Answer:

f(1)=-11

f(n)=f(n-1)+22

Step-by-step explanation:

Base equation:

f(n)=-11+22(n-1)

f(1)=-11+22(1-1)

f(1)=-11+0

f(1)=-11

f(n)=-33+22n

f(n-1)=-11+22(n-2)

f(n-1)=-55+22n

-33+22n=-55+22n+x

22n gets canceled out

-33=-55+x

-33+55=x

x=22

f(n)=f(n-1)+22

Determine the value(s) for which the rational expression 2x^2/6x is undefined. If there's more than one value, list them separat
Dmitry [639]

Answer:

0

Step-by-step explanation:

Hello, dividing by 0 is not defined. so

\dfrac{2x^2}{6x}

is defined for x different from 0

This being said, we can simplify by 2x

\dfrac{2x^2}{6x}=\dfrac{2x*x}{3*2x}=\dfrac{1}{3}x

and this last expression is defined for any real number x.

Thank you

Please help me with this.A rectangular field is
Karolina [17]
First, let's get the perimeter of the rectangle:
P=2W+2L
P=130m+210m
P=340m
Then, let's get the area of the bigger one:
A=WL
A=65m*105m
A=6825m^2

Then let's try using a rectangle with a smaller ratio:
P=100m+240m
P=340m
Then:
A=50m*120m
A=6000m^2

If you used a square:
P=170+170
P=340
A=WL
A=85^2
A=7225

There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.

I really need help on this one, guys
Gennadij [26K]

Answer:

6.2 meters

Step-by-step explanation:

Use pythagorean theorem to find b:

b = √(2.8² - 2.7²) = √0.55 = 0.7 (nearest tenth)

Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7

Perimeter = 6.2 meters
