Suppose y varies inversely with X, and y = 48 when x = 3. What is the value of x when y = 24?

olganol [36]

Answer:

C. 6

Step-by-step explanation:

Recall that inverse variation is given by:

$\displaystyle y=\frac{k}{x}$

Where k is the constant of variation.

We know that y = 48 when x = 3. Substitute:

$\displaystyle (48)=\frac{k}{(3)}$

Solve for k:

$k=3(48)=144$

Hence, our equation is:

$\displaystyle y=\frac{144}{x}$

We want to find x when y = 24. Substitute:

$\displaystyle \frac{24}{1}=\frac{144}{x}$

Cross-multiply:

$24x=144$

Divide both sides by 24. Hence:

$x=6$

Our answer is C.

Use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following

vivado [14]

Answer: (-0.4, 6.8)

The graph is attached

Step-by-step explanation:

We can find the axis of symmetry using the formula x = -b/2a

x = - -4/2(-5)

x = 4/-10

x = 0.04

Substitute for x and calculate y

y = $\left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6$

y = 6.8

Answer:

3.508 kilograms

Step-by-step explanation:

This question can be solved using a rule of three.

We have that each kilogram is 1000 grams. How many kilograms are there for 3508 grams?

1kg - 1000g

xkg - 3508g

$1000x = 3508$

$x = \frac{3508}{1000}$

$x = 3.508$

So the correct answer is:

3.508 kilograms
