Pls help me with this

LiRa [457]

Answer:

In this order from top to bottom, you get -12, -8, 0, 6, and 8

Step-by-step explanation:

You simply plug in the X value into each equation where it is needed.

So for the first one

2(-5)-2 = -10-2 = -12

2(-3)-2 = -6-2 = -8

2(1)-2 = 2-2 = 0

2(4)-2 = 8-2 = 6

2(5)-2 = 10-2 = 8

A rectangular parcel of land has an area of 3,000 ft2. A diagonal between opposite corners is measured to be 10 ft longer than o

Kazeer [188]

Answer:

40 ft × 75 ft

Step-by-step explanation:

Let x be the one side ( in feet ) of the rectangular parcel,

So, the diagonal between opposite corners = ( x + 10 ) feet,

Let y be the other side of the rectangle ( adjacent to side x ),

The area of the rectangle,

A = x × y,

According to the question,

A = 3000 square ft,

$\implies xy = 3000\implies y=\frac{3000}{x}$

∵ In a rectangle,

$D^2=a^2+b^2$

Where, a and b are the adjacent side of the rectangle and D is the diagonal,

$(x+10)^2 = x^2 + y^2$

$(x+10)^2 = x^2 + \frac{9000000}{x^2}$

$x^2(x+10)^2 = x^4 + 9000000$

$x^2(x^2+100+20x) = x^4 + 9000000$

$x^4+100x^2 + 20x^3 = x^4 + 9000000$

$20x^3 + 100x^2 - 9000000=0$

$x^3 + 5x^2 - 450000 = 0$

By graphing the equation,

We found that,

The only real zeros of the equation is at x = 75,

Hence, the one side of the rectangle = 75 ft,

And, second side = $\frac{3000}{75}$ = 40 ft

Hence, the dimension of the land is 40 ft × 75 ft

If cot O= 12/5, find tan O

Flura [38]

Answer: Tan O= 5/12

Step-by-step explanation:

Cot O=12/5

Looking at the pythagoras theory

Cot= 1/tan

Cot O=1/tango

Cross multiply

CotO tan O=1

Make tan the subject of formula

TanO= 1/Cot O

Cot O=12/5

Substitute for cot O

Tan O= 1/12/5

Tan O= 5/12

James currently has $215 in a savings account. Every month, he deposits an additional $45 into his account. James had to replace

Romashka-Z-Leto [24]

Answer:

James still owes 1,261 dollars after 12 months

Step-by-step explanation:

<u>Second attempt :P</u>

James currently has 215 dollars, every month for 12 months, he deposits 45 dollars into his account

215 + 12 x 45

215 + 540 =755

Now we know how much money James will have after 12 months, we need to find out how much he will owe.

James has to pay 168 per month for 12 months

168 x 12 = 2016

After 12 months the total amount James owes will be 2,016 dollars.

He makes 755 for the whole 12 months

2,016 - 755 = 1,261

James still owes 1,261 dollars after 12 months
