Find the coordinates of the centroid of triangle RST. SHOW YOUR WORK so I can see if the answer makes sense (no links)

zimovet [89]

Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).

The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.

<em>x</em>-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1

<em>y</em>-coordinate: (5 + 1 - 3)/3 = 3/3 = 1

So the centroid is (1, 1).

Solve the equation by completing the square. Round to the nearest hundredth if necessary. X^2 + 5x-10=0

viktelen [127]

$(*)\\(a+b)^2=a^2+2ab+b^2$

$x^2+5x-10=0\ \ \ |+10\\\\x^2+2\cdot x\cdot2.5=10\ \ \ |+2.5^2\\\\\underbrace{x^2+2\cdot x\cdot2.5+2.5^2}_{(*)}=10+2.5^2\\\\(x+2.5)^2=16.25\to x+2.5=\pm\sqrt{16.25}\\\\x+2.5\approx-4.03\ \vee\ x+2.5=4.03\ \ \ |-2.5\\\\x\approx-6.53\ \vee\ x\approx1.53$

A study found that a driver’s reaction time A(x) to audio stimuli and his or her reaction time V(x) to visual stimuli (both in m

amid [387]

Answer:

The required inequality is $0.0001 x^2 - 0.089 x - 7$ .

Step-by-step explanation:

The given inequalities are

$A(x) = 0.0051x^2 - 0.319x + 15$

$V(x)= 0.005x^2 - 0.23x + 22$

where, x is the driver's age (in years), A(x) is driver’s reaction time to audio stimuli and V(x) is his or her reaction time to visual stimuli, 16 ≤ x ≤ 70.

We need to find an inequality that can be use to find the x-values for which A(x) is less than V(x).

$A(x)$

$0.0051x^2 - 0.319x + 15< 0.005x^2 - 0.23x + 22$

$0.0051x^2 - 0.319x + 15- 0.005x^2 + 0.23x- 22$

Combine like terms.

$0.0001 x^2 - 0.089 x - 7$

where, 16 ≤ x ≤ 70.

Therefore, the required inequality is $0.0001 x^2 - 0.089 x - 7$ .
