Solve: y= 7/3x-3 and y=11

Travka [436]

Answer:

x = 6

Step-by-step explanation:

Given

y = $\frac{7}{3}$ x - 3 and y = 11, thus

$\frac{7}{3}$ x - 3 = 11 ( add 3 to both sides )

$\frac{7}{3}$ x = 14

Multiply both sides by 3 to clear the fraction

7x = 42 ( divide both sides by 7 )

x = 6

The height of a stuntperson jumping off a building that is 20 m high is modeled by the equation h = 20 – 5t2, where t is the tim

Leno4ka [110]

<h2>Time Interval : 1 sec to 1.414 sec</h2>

Step-by-step explanation:

The height of the stuntperson jumping off a $20\text{ }m$ is modelled as $h\text{ }=\text{ }20\text{ }-\text{ }5t^{2}$ . Here $t$ is the time in seconds.

We have to record the person when he is between the heights $15\text{ }m\text{ and }10\text{ }m$ from the ground.

When $h\text{ }=\text{ }15$ ,

$15\text{ }=20\text{ }-\text{ }5t^{2}\\5t^{2}\text{ }=\text{ }5\\t^{2}\text{ }=\text{ }1\\t\text{ }=\text{ }1\text{ }sec$

When $h\text{ }=\text{ }10$ ,

$10\text{ }=20\text{ }-\text{ }5t^{2}\\5t^{2}\text{ }=\text{ }10\\t^{2}\text{ }=\text{ }2\\t\text{ }=\text{ }\sqrt{2}\text{ }=\text{ }1.414\text{ }sec$

The stuntperson is at height $15\text{ }m$ at $t\text{ }=\text{ }1\text{ }sec$ , and is at height $10\text{ }m$ at $t\text{ }=\text{ }1.414\text{ }sec$ .

∴ The camera should film the person for the time interval $\textbf{1}\text{ }sec\text{ to }\textbf{1.414}\text{ }sec$ .

Butoxors [25]

Answer:

The correct answers are B and C.

Step-by-step explanation:

3/10 + 1 represents an extra 30%, plus 100%. The 100% accounts for the original power of the spell. The expression can be simplified as 1.3H, or 130% of H. 130% of H can also be represented as 130/100 H.
