13-(x+5)=4x-2 what is x?

1 answer:

6 0

First simplify-
13-(x+5)=4x-2
13-x+5=4x-2
18-x=4x-2
Then isolate the variable-
20=5x
And last, divide both sides by 5 to get just x (not 5 x)-
x=4

Question 17

Romashka [77]

The quadratic function that models the data given in the table is 203.8x² - 26.6x + 8.6

<h3>What is the quadratic function?</h3>

A quadratic function is an equation that usually has a single variable and it is raised to the power of 2.

A quadratic function has the form : ax² + bx + c = 0

Where: a, b,c are known numbers and x is unknown

Given the quadratic function: 185x²+ 1.

Number of views when 1 day has passed = 185(1) + 1 = 186
Number of views when 6 days has passed = 185(6²) + 1 = 6661

Given the quadratic function: 203.8x² - 26.6x + 8.6

Number of views when 1 day has passed = 203.8(1)² - 26.6(1)+ 8.6 = 185.80
Number of views when 6 days has passed = 203.8(6)² - 26.6(6) + 8.6 = 7185.80

Hello , how to do 6(iii)?

Doss [256]

Answer:

$\displaystyle \frac{dS}{dt}=\frac{3}{50r}$

Step-by-step explanation:

Water is being pumped into an inflated rubber sphere at a constant rate of 0.03 cubic meters per second.

So, dV/dt = 0.03.

We want to show that dS/dt is directly proportional to 1/r.

In other words, we want to establish the relationship that dS/dt = k(1/r), where k is some constant.

First, the volume of a sphere V is given by:

$\displaystyle V=\frac{4}{3}\pi r^3$

Therefore:

$\displaystyle \frac{dV}{dt}=4\pi r^2\frac{dr}{dt}$

Next, the surface area of a sphere S is given by:

$\displaystyle S=4\pi r^2$

Therefore:

$\displaystyle \frac{dS}{dt}=8\pi r\frac{dr}{dt}$

We can divide both sides by 2:

$\displaystyle \frac{1}{2}\frac{dS}{dt}=4\pi r\frac{dr}{dt}$

We can substitute this into dV/dt. Rewriting:

$\displaystyle \frac{dV}{dt}=r\Big(4\pi r\frac{dr}{dt}\Big)$

So:

$\displaystyle \frac{dV}{dt}=\frac{1}{2}r\frac{dS}{dt}$

Since dV/dt = 0.03 or 3/100:

$\displaystyle \frac{3}{100}=\frac{1}{2}r\frac{dS}{dt}$

Therefore:

$\displaystyle \frac{dS}{dt}=\frac{3}{50r}=\frac{3}{50}\Big(\frac{1}{r}\Big)$

Where k = 3/50.

And we have shown that dS/dt is directly proportional to 1/r.
