Match the real-world problem to its constant of proportionality.

OleMash [197]

Answer:

6.12

1.39

4.12

Step-by-step explanation:

If y ∝ x, then y = kx.

So, the constant of proportionality is given by $k = \frac{y}{x}$

Case 1:

$18.36 for 3 pizzas

Therefore, the constant of proportionality is $\frac{18.36}{3} = 6.12$

Case 2:

$4.17 for 3 pounds of bananas.

Hence, the constant of proportionality is $\frac{4.17}{3} = 1.39$

Case 3:

$16.48 for 4 pounds of potatoes.

Hence, the constant of proportionality is $\frac{16.48}{4} = 4.12$

Case 4:

2 cups of flour to make 24 cookies.

Hence, the constant of proportionality is $\frac{24}{2} = 12$ (Answer)

! + 3 − 5 = 0; by completing the square

mylen [45]

Answer:

x = 1.19258 and x = −4.19258

Step-by-step explanation:

The given equation is :

$x^2+3x-5=0$

Keep x terms on the left and move the constant to the right side by adding it on both sides.

$x^2+3x=5$

Take half of the x term and square it.

$(3\times \dfrac{1}{2})^2=\dfrac{9}{4}$

then add the result to both sides

$x^2+3x+\dfrac{9}{4}=5+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{29}{4}\\\\(x+\dfrac{3}{2})=\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}+\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}-\sqrt{\dfrac{29}{4}}$

So,

x = 1.19258 and x = −4.19258

Hence, this is the required solution.

What is the relative maximum of the function?

Stels [109]

Answer:

(1, 4)

Ste-step explanation:

The relative max of this function is read directly from the graph: 4. This value of y occurs when x = 1.
