Answer:

Step-by-step explanation:

$\left \{ {{-3x+2y=56} \atop {-5x-2y=24}} \right. \left \{ {-3x+2y=56} \atop -8x=80} \right.< => \left \{ {-3x+2y=56} \atop x= -10} \right. \left \{ {-3.-10+2y=56} \atop x= -10} \right. \left \{ {2y=26} \atop x= -10} \right. \left \{ {y=13} \atop x= -10} \right.$

3241004551 [841]

Answer:

Step-by-step explanation:

202 students taking math and are business majors

only math, would be (861 - 202) = 659

only business majors, would be (525 - 202) = 323

so there are (659 + 323) = 982 that are math or business majors

Which ordered pair is included in the solution set to the following system?

Nataliya [291]

The ordered pair is included in the solution set to the following system is (0,2)

<h3>Set of inequalities</h3>

Given the set of inequalities

y > x2 + 1

y < x2 – x + 1

Equate both expressions to have:

x^2 + 1 = x^2 - x +1

1 = -x + 1

x = 0

Substitute x = 0 into any of the function

y = x^2 + 1

y = 1

This shows that the ordered pair is included in the solution set to the following system is (0,2)

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.

Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

$F = 10[v(21) - v(16)]$

Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:

$F = ma$

In this problem, mass of 50 kg, thus $m = 50$

Acceleration is <u>change in velocity divided by change in time</u>, that is:

$a = \frac{\Delta_v}{\Delta_t}$

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

$\Delta_t = 21 - 16 = 5$

$\Delta_v = v(21) - v(16)$

Thus, the force is given by:

$F = ma$

$F = m\frac{\Delta_v}{\Delta_t}$

$F = 50\frac{[v(21) - v(16)]}{5}$

$F = 10[v(21) - v(16)]$
