Answer:

first number=6

second number=8

third number= 10

fourth number= 12

Step-by-step explanation:

first number=a

second number=b

third number= c

fourth number= d

we have the following equations

a=2n equation 1

b=2n+2 equation 2

c=2n+4 equation 3

d=2n+6 equation 4

a+b+c+d=36 equation 5

using equations 1, 2, 3 and 4 in equation 5 we have

2n+2n+2+2n+4+2n+6=36

8n+12=36

8n=36-12

8n=24

n=24/8=3

so we have

a=2*3=6 =first number

b=(2*3)+2=8= second number

c=(2*3)+4=10=third number

d=(2*3)+6=12=fourth number

If f (x) = 2 x + 5 and three-halves are inverse functions of each other and f (x) = 2x + 5, what is

marusya05 [52]

Answer:

See explanation

Step-by-step explanation:

The question has conflicting details

$f(x) = 2x + 5$

$f(x) = 2x + 5$ and three halves doesn't sound correct.

So, I will take f(x) as

$f(x) = 2x + 5$

Next, solve for the inverse function

Replace f(x) with y

$y = 2x + 5$

Swap x and y

$x = 2y + 5$

Make 2y the subject

$2y = x-5$

Make y the subject

$y = \frac{x-5}{2}$

Replace y with the inverse sign

$f^{-1}(x) = \frac{x-5}{2}$

So, now we can calculate any value from the original function and from the inverse function.

For instance:

$f^{-1}(7) = \frac{7-5}{2} = \frac{2}{2} = 1$

$f(1) = 2*1 + 5 = 2+5=7$

Answer:

5,720,000 Sq Feet.

Step-by-step explanation:

They are asking the Area of a Trapezoid

Equation =( base + base / 2) x height

Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.

So if you multiply them (200 x 260) You will get 52000.

Now we divide that by 2. (52000 / 2 = 26000)

Now it says the straight line is 220. I think this refers to the height.

Now we multiply 26000 x 220. Which is 5720000.

Its a pretty big number, but that is the answer! :)

Hope this helps!

Find the simplified product 2 square root 5x^3(-3 square root 10x^2

Ivanshal [37]

The simplified product of $2\sqrt{5x^{3} }$ and -3 $\sqrt{10x^{2} }$ is -30 $x^{5/2} \sqrt{2}$ .

Given Two expressions: -3 $\sqrt{10x^{2} }$ and 2 $\sqrt{5x^{3} }$ .

We have to multiply both the expressions and it can be done as under:

-3 $\sqrt{10x^{2} }$ *2 $\sqrt{5x^{3} }$

Firstly we have to multiply -3 with 2 to get

=-6 $\sqrt{10x^{2} }\sqrt{5x^{3} }$

Then we have to find square root of x cube and x square which is x to the power 3/2 and x to the power 1.

= $-6x^{3/2} x\sqrt{10}\sqrt{5}$

Now we have to multiply both the numbers in the root to get the answer;

=-6 $x^{5/2} \sqrt{50}$

Square root of 50 is 5 root 2.

=-6*5 $\sqrt{2}$ $x^{5/2}$

=-30 $\sqrt{2}$ $x^{5/2}$

Hence the simplified product is -30 $\sqrt{2}$ $x^{5/2}$ .
