Answer:

b = 15 is the solution of equation.

Step-by-step explanation:

We have given the following equation:

b+6 = 21

We have to solve the above equation.

First, adding -6 to both sides of equation we get,

b+6-6 = 21 - 6

b= 21 - 6

b = 15

b = 15 is the solution of equation.

Answer:

b=15

Step-by-step explanation:

Okay so if we are solving for B the first thing you need to do is subtract 6 on both sides because we are trying to get alone

b+6=21

-6 -6

21-6=15

b=15

<h3>Answer:</h3>

B). y = (x -3)(x +1)(x -1)

<h3>Step-by-step explanation:</h3>

The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).

Selection B is the only choice that has these three factors.

The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use thi

Katyanochek1 [597]

Answer:

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = $-5x^2$

first Determine the value of F'(x)

F'(x) = $\frac{d(-5x^2)}{dy}$

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = $\frac{d(-10x)}{dy}$

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x) $= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }$

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

7. Marie can make 12 small mango pies for every 10 mangoes. How many pie

Marysya12 [62]

Answer:

D. <em>Marie can make 60 pies</em>.

Step-by-step explanation:

In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:

A. <em>Marie can make 30 pies</em>.

$x = \frac{10\,mangoes}{12\,pies}\times 30\,pies$

$x = 25\,mangoes$

25 mangoes are required for producing 30 pies.

B. <em>Marie can make 40 pies</em>.

$x = \frac{10\,mangoes}{12\,pies}\times 40\,pies$

$x = 33.333\,mangoes$

34 mangoes are required for producing 40 pies.

C. <em>Marie can make 50 pies</em>.

$x = \frac{10\,mangoes}{12\,pies}\times 50\,pies$

$x = 41.667\,mangoes$

42 mangoes are required for producing 50 pies.

D. <em>Marie can make 60 pies</em>.

$x= \frac{10\,mangoes}{12\,pies}\times 60\,pies$

$x = 50\,mangoes$

50 mangoes are required for producing 60 pies.

The complete statement is: <em>Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes. </em>

Hence, correct answer is D.
