Area/4= pi(r)^2/4
a/4=pi(40)^2/4
a/4=pi(1600)/4
area is about 5026.5/4
a/4=5026.5/4
a=1256.6

x=1 or x= 12

Step-by-step explanation:

x²-13x+12=0

x²-12x-x+12=0

x(x-12)-1(x-12)=0

(x-1)(x-12)=0

x-1=0 or x-12=0

x=1 or x=12

Find the equation of the line through point (10,4) and parallel to 3x+5y=8. Use a slash ("/") for fractions (e.g. 1/2 for 12). D

MAXImum [283]

Answer:

3x + 5y = 50

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3x + 5y = 8 ( subtract 3x from both sides )

5y = - 3x + 8 ( divide terms by 5 )

y = - $\frac{3}{5}$ x + $\frac{8}{5}$ ← in slope- intercept form

with slope m = - $\frac{3}{5}$

Parallel lines have equal slopes , then

y = - $\frac{3}{5}$ x + c ← is the partial equation

to fid c substitute (10, 4 ) into the partial equation

4 = - 6 + c ⇒ c = 4 + 6 = 10

y = - $\frac{3}{5}$ x + 10 ← equation of parallel line in slope- intercept form

multiply through by 5 to clear the fraction

5y = - 3x + 50 ( add 3x to both sides )

3x + 5y = 50 ← equation of parallel line in standard form

10. Horizontal shift of 50, vertical shift of -20, horizontal shift of -50. Think of it on a plane, with right in the positive x-axis and up in the positive y-axis. The cans go right 50ft, then down 20ft, then left 50ft. In terms of the horizontal and vertical, they go 50ft in the positive horizontal axis, then 20ft in the negative vertical axis, then 50ft in the negative horizontal axis. Therefore, the cans have a horizontal shift of 50, then a vertical shift of -20, then a horizontal shift of -50.

11. Since the partition and the wall are parallel, the triangles are similar. This means that the ratio between the sides are the same for the small triangle and the big triangle. The small triangle (made by the partition) is 3m wide and 2m tall. Since the big triangle (made by the wall) is 4m tall, the sides of the big triangle are twice the size of the small triangle. Therefore, the big triangle is 6m wide. We cannot forget to subtract the 3m from the small triangle, since we only want to know how far the partition is from the wall, not how far the point is from the wall.
The wall is 3m away from the partition.

For the polynomial below,what is the power of the term with the coefficient of 1? X^3+1/3x^4+6x+5

valentina_108 [34]

Original Polynomial
${x}^{3} + \frac{1}{ {3x}^{4} } + 6x + 5$
Coefficient Concept Expansion
$1 \times {x}^{3} = {x}^{3}$
The Power of the term with 1 as the coefficient is 3.

A coefficient is a number multiplied by some variable. For instance, 4x has a coefficient of 4 or 56x has a coefficient of 56.
