URGENT!! Please help Find the values of y=c(x) 3 square x, for x = 0, 0.008, 0.027, 0.064, 0.125, 0.216, 0.343, 0.512, , 0.729 a

mojhsa [17]

Answer:

We have

$y=c(x)=\sqrt[3]{x}$

$\text{for } x = 0, 0.008, 0.027, 0.064, 0.125, 0.216, 0.343, 0.512, 0.729 \text{ and } 1$

We have 10 points to find:

$\text{Point A}(0, 0)$

$\text{Point B}(0.008, 0.2)$

$\text{Point C}(0.027, 0.3)$

$\text{Point D}(0.064, 0.4)$

$\text{Point E}(0.125, 0.5)$

$\text{Point F}(0.216, 0.6)$

$\text{Point G}(0.343, 0.7)$

$\text{Point H}(0.512, 0.8)$

$\text{Point I}(0.729, 0.9)$

$\text{Point J}(1, 1)$

A certain car traveling at 34.0 mph skids to a stop in 29 meters from the point where the brakes were applied. in approximately

Orlov [11]

<span>Using the kinematic equations: (final velocity)^2 = (initial velocity)^2 - 2 * acceleration * distance Assuming the acceleration/deceleration on the car is constant from a constant force on the brakes. Converting from mph to m/s using 0.447 (so 34 mph is 15.2 m/s) (0)^2 = (15.2)^2 - 2 * acceleration * 29 acceleration = 4.0 m/s^2 Had the car been going 105.4 mph (47.1 m/s) (0)^2 = (47.1)^2 - 2 * 4 * distance distance = 277 meters</span>

The square of a number decreased by 3 times the number 28 find all possible values for the number

stealth61 [152]

Question:

The square of a number decreased by 3 times the number is 28 find all possible values for the number

Answer:

The possible values of number are 7 and -4

Solution:

Given that the square of a number decreased by 3 times the number is 28

To find: all possible values of number

Let "a" be the unknown number

From given information,

square of a number decreased by 3 times the number = 28

$a^2 - 3a = 28$

$a^2 - 3a - 28 = 0$

Let us solve the above quadratic equation

$\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0$

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Using the above formula,

$\text { For } a^{2}-3 a-28=0 \text { we have } a=1, b=-3, c=-28$

$\begin{aligned}&a=\frac{-(-3) \pm \sqrt{(-3)^{2}-4(1)(-28)}}{2 \times 1}\\\\&a=\frac{3 \pm \sqrt{9+112}}{2}\\\\&a=\frac{3 \pm \sqrt{121}}{2}=\frac{3 \pm 11}{2}\\\\&a=\frac{3+11}{2} \text { or } a=\frac{3-11}{2}\\\\&a=7 \text { or } a=-4\end{aligned}$

Thus the possible values of number are 7 and -4

Raina is on the swim team. Each day she swims 750m . How far does she swim in 5 days?

Sav [38]

1 day = 750 m

1 * 7 = 750 * 7

7 days = 5250 m

Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000

5250 / 1000

= 5.25 km

Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.

Hope this helps!
