The formula for circumference is 2 x PI x r

Using the circumference we can find the radius:

50.24 = 2 x PI x r

Multiply 2 by PI:

2 x 3.14 = 6.28

50.24 = 6.28 x r

Divide both sides by 6.28:

R = 50.24 / 6.28

R = 8

The radius is 8 units.

Answer:

$\boxed{(f \times g)(x) = 3 {x}^{2} + 11x + 10}$

Given:

$f(x) = x + 2 \\ \\ g(x) = 3x + 5$

To Find:

$(f \times g)(x) = f(x) \times g(x)$

Step-by-step explanation:

Given -3x + 2y = 1 and x = 5, solve for y. a.-7 b.7 c.-8 d.8

eduard

Answer:

d. 8

Step-by-step explanation:

Given: -3x + 2y = 1 and x = 5

Now plug x =5 in the given equation and find the value of y.

-3(5) + 2y = 1

-15 + 2y = 1

2y = 1 + 15

2y = 16

Dividing both sides by 2, we get

y = 8

Thank you.

Traduce el enunciado a expresión algebraica La suma de dos números pares consecutivos

garri49 [273]

Answer:

The answer is "Expression: x+(x+2)".

Step-by-step explanation:

Given:

The sum of two consecutive even numbers

Proving:

Let,

The First number is = x

The second consecutive number is = x+2

Calculating value by adding value:

Expression:

$\Rightarrow x+(x+2)\\\\$

when x= 1, 2, 3 .... it gives:

$\Rightarrow 1+(1+2)= 1+3=4\\\\\Rightarrow 2+(2+2)= 2+4=6\\\\\Rightarrow 3+(3+2)= 3+5=8\\$

That's why the sum of consecutive numbers is even.
