Answer: The required value of x is given by

$x=-7.$

Step-by-step explanation: We are given to solve the following equation for the value of x:

$\dfrac{3}{5}x+5=\dfrac{4}{5}~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

In order to solve the above equation, we need to take 5 to the right-hand side of the equation and then solve for x.

The solution of equation (i) is as follows:

$\dfrac{3}{5}x+5=\dfrac{4}{5}\\\\\\\Rightarrow \dfrac{3}{5}x=\dfrac{4}{5}-5\\\\\\\Rightarrow \dfrac{3}{5}x=\dfrac{4-25}{5}\\\\\\\Rightarrow \dfrac{3}{5}x=-\dfrac{21}{5}\\\\\\\Rightarrow x=-\dfrac{21\times 5}{5\times 3}\\\\\\\Rightarrow x=-\dfrac{21}{3}\\\\\\\Rightarrow x=-7.$

Thus, the required value of x is given by

$x=-7.$

During a recent eruption, the volcano spewed out copious amount of ash. One small piece of ash was ejected from the volcano with

nlexa [21]

For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.

Find the equation of the line that contains the point (4,-2) and is perpendicular to the line y=-2x+8.

snow_tiger [21]

Answer:

$\frac{1}{2} x - 4$

Step-by-step explanation:

Perpendicular lines will have slopes that are the multiplicative additive inverse of each other: a line with slope 3/4 is perpendicular to a line with slope -4/3, for example. You need a line that is perpendicular to a line with slope -2 (reading that from the -2 in the -2x portion of the given equation, which is written in slope-intercept form), so your new line must have slope +1/2.

With the slope and a point, we can come up with an equation using this formula:

y - y-coordinate = slope (x - x-coordinate)

So we have y - (-2) = 1/2 (x - 4).

Simplify the equation: y + 2 = 1/2 x - 2

Subtract 2 from both sides: y + 2 - 2 = 1/2 x - 2 - 2

Simplify: y = 1/2 x - 4.

Suppose a city with population 600,000 has been growing at a rate of 3% per year. If this rate continues, find the population

andrezito [222]

Answer:

The answer should be around 1,149663 (Rounded off to the nearest whole number. Also if a population has a remainer you usually add it as 1. This is because these are people)

Step-by-step explanation:

First step involves listing the formulas being used:

600,000= population, 0.03= growth rate 22years= period

Therefore, we take the 600,000 and multiply by 1+0.03 ^22(to the power of 22 or period)

So, 600,000(1+0.03)^22

=1,149662.045 /1,149663

Hope this helps!
