(8v3-80v2+6)\(v-10)

Mathematics
1 answer:
Leto [7]3 years ago
8 0

\frac{(8v^3-80v^2+6)}{v-10}

Use long division for dividing

(8v^3-80v^2+6) Here 'v' term is missing so we use 0vW

Divide (8v^3-80v^2+0v+6) by v-10 using long division

Step 1: Put 8v^2 at the top

step 2: multiply 8v^2 with v-10  and put it at the bottom

step 3: subtract it

We will get remainder 6

so quotient is  8v^2

Remainder is 6

I need to find the perimeter and area of the regular polygon.
mezya [45]
The area of a polygon is given by the formula Area = ap/2 where a is the length of the apothem and p is the perimeter. The apothem is a line from the center of the polygon perpendicular to a side.

Depending on the formula you know, you can find the length of a side in 1 of 2 ways. 

The first way uses a triangle. Using the radius of the polygon you can create 8 congruent triangles. The center angle will be 360 / 8 = 45 and two side lengths of 20. You can find the length of the base using the law of cosines.

c^2 = 20^2 + 20^2 - 2(20)(20)(cos 45)
c^2 = 400 + 400 - 800(cos 45)
c^2 = 800 - 800(cos 45)
c = sqrt(800 - 800(cos 45)
c = 15.31

The second way is to use this formula:
r = s / (2 sin(180 / n))
20 = s / (2 sin(180/8)
(20)(2)sin(22.5) = s
(40)sin(22.5) = s
s = 15.31

We need to calculate the perimeter. As there are 8 sides (8)(15.31) = 122.48
Now we need to calculate the apothem using

a = S / (2 tan (180 / n)
a = 15.31 / (2 tan (180 / 8))
a = 18.48

Now solve for the area

Area = ap/2
Area = (18.48)(122.48)/2
Area = 1131.72

perimeter = 122.48
area = 1131.72

FromTheMoon [43]

Answer:

60

Step-by-step explanation:

What we know:

  • ABD is a straight angle, it measures 180 degrees
  • Angle CBA + CBD = 180 degrees
  • Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9     /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°

The population of a town was 10,000 in 2018. Each year the town's population grows by 23%. Let x=0 be the year 2018. Create the
Naily [24]

Answer:

 f(x)=10000(1.23)^x

Step-by-step explanation:

We are going to apply algebra to solve for the exponential growth

we know that the expression for the exponential formula is

y = ab^x.

where

a = the amount before measuring growth or decay

= 10,000

r = growth or decay rate = 23%= 0.23

x = number of time intervals that have passed

since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)

hence the formula becomes

y = a(1+r)^x.

f(x)=10000(1+0.23)^x \\\\f(x)=10000(1.23)^x

The expression that will give the population value is

f(x)=10000(1.23)^x
