Does anyone know if that little ‘o’ by the ‘V’ means it’s a base of 10?

Your screenshot is cut off. Without seeing more context, it's hard to say. But usually the little 'o' is often a zero indicating an initial value. It's simply a way to label V in a different way. So you can tell V apart from $V_o$

Can someone help me please

lianna [129]

Answer:

y=-3/5x+4

Step-by-step explanation:

Pick any two points the line goes through.

I picked

(0,4) and (5,1)

There are a few ways to do this but ultimately, it’s the same concept. I will use slope-intercept form which for me was always easier.

y=mx+b where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis which in this case is point (0,4) so the b=4.

To find the slope, use rise/run between the two points you chose. Point (5,1) is 3 units UNDER point (0,4) so now we have -3/run because -3 is the “rise”. After you count down 3 units always go right. After going right 5 units, you touch point (5,1). So the “run” is 5. Which means that the slope is -3/5.

m=-3/5 and b=4

So the equation is:

y=-3/5x+4

Hope this helps!!

You are in charge of finding a venue for a concert. With the average square feet per

stiks02 [169]

Answer:

Step-by-step explanation:

<u>Proportions</u>

We'll use proportions to answer the question and find the number of students fit into a building of 300 ft x 300 ft. The area of the building is

$300\ in\times 300\ in=90000\ in^2$

We are given a factor of 2.05 students per square feet, thus the number of students that fit into the building is

$2.05\cdot 90000\ in^2=184500$

Since 184500 is greater than 142551 people required, they easily fit into that space.

The closest answer is

184,499 will fit, Yes

Dan invests £18790 into his bank account. He receives 4.9% per year simple interest. How much will Dan have after 3 years? Give

garri49 [273]

Answer:

£21552.

Step-by-step explanation:

Given information:

Principal amount = £18790

Rate of simple interest =4.9% = 0.049 per year

Time = 3 years

Formula for simple interest:

$I=P\times r\times t$

where, P is principal, r is rate of interest and t is time in years.

$I=18790\times 0.049\times 3$

$I=2762.13$

Total amount after 3 year is

$A=P+I$

$A=18790+2762.13$

$A=21552.13$

$A\approx 21552$

Therefore, Dan have £21552 after 3 years.

If x+1/x= 3, then prove that m^5+1/m^5= 123

Explanation:

We can start with the relations ...

$\displaystyle\left(x+\frac{1}{x}\right)^3=\left(x^3+\frac{1}{x^3}\right)+3\left(x+\frac{1}{x}\right)\\\\\left(x+\frac{1}{x}\right)^5=\left(x^5+\frac{1}{x^5}\right)+5\left(x^3+\frac{1}{x^3}\right)+10\left(x+\frac{1}{x}\right)\\\\\textsf{From these, we can derive ...}\\\\x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(\left(x+\frac{1}{x}\right)^3-3\left(x+\frac{1}{x}\right)\right)-10\left(x+\frac{1}{x}\right)$

$\displaystyle x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(x+\frac{1}{x}\right)^3+5\left(x+\frac{1}{x}\right)\right)\\\\x^5+\frac{1}{x^5}=3^5 -5(3^3)+5(3)\\\\=((3^2-5)3^2+5)\cdot3=(4\cdot9+5)\cdot3=(41)(3)\\\\=\boxed{123}$
