1. is he equation true , false, or open

RideAnS [48]

Question 1:

For this case we have the following equation:

$5x ^ 2 = 6x + 11$

We observe that the equation is a polynomial of the second degree.

Therefore, the equation has two possible solutions.

The variable of the equation for this case is x.

In this case, we have an open equation because we have a variable.

Rewriting the equation we have:

$5x ^ 2 - 6x - 11 = 0$

Answer:

open, there is a variable.

Question 2:

For this case we have the following equation:

$2-8x = -6$

From here, we must clear the value of x.

For this, we follow the following steps:

1) Pass the value of 8x adding:

$2 = -6 + 8x$

2) Pass the value of 6 adding:

$2 + 6 = 8x$

3) Add the values on the same side of equality:

$8x = 8$

4) Pass the 8 to divide:

$x = \frac{8}{8} = 1$

Answer:

The value of x is given by:

$x = 1$

Question 3:

For this case we have the following equation:

$y = x-4$

The ordered pair solution is the one that satisfies both sides of the equation.

For the point (6, 2) we have:

$x = 6 y = 2$

Substituting values we have:

$2 = 6-4 2 = 2$

We observe that both sides of the equation are equal.

Therefore, the ordered pair solution is (6, 2)

Answer:

An ordered pair that is a solution of the equation y = x-4 is:

(6, 2)

Answer:

the graph where it's going up (right)

Step-by-step explanation:

if you double 40 it will be 80. double 80 and you get 160 etc etc. this means the total bacteria only grows and the graph has to go all the way up

sand falls from an overhead bin and accumulates in a conical pile with a radius that is always four times its height. suppose th

blagie [28]

Answer:

$\frac{dv}{dt} =7239.168 cm/sec$

Step-by-step explanation:

From the question we are told that:

Rate $\frac{dh}{dt}=1cm$

Height $h=12cm$

Radius $r=4h$

Generally the equation for Volume of Cone is mathematically given by

$V=\frac{1}{3}\pi r^2h$

$V=\frac{1}{3}\pi (4h)^2h$

Differentiating

$\frac{dv}{dt} =\frac{16}{3}\pi3h^2\frac{dh}{dt}$

$\frac{dv}{dt} =\frac{16}{3}*3.142*3*12^2*1$

$\frac{dv}{dt} =7239.168 cm/sec$
