Solve the following quadratic equation.
(1 - 18)2 = 1
OA
x = 19 and x = 17
OB.
x= -19 and x = .17
OC. x= -19 and x = 17
D.
x = 19 and x=-17

Answers

Answer 1

Given:

Consider the given equation is

[tex](x-18)^2=1[/tex]

To find:

The values of x.

Solution:

We have,

[tex](x-18)^2=1[/tex]

Taking square root on both sides, we get

[tex]x-18=\pm\sqrt{1}[/tex]

[tex]x-18=\pm 1[/tex]

Adding 18 on both sides, we get

[tex]x-18+18=\pm 1+18[/tex]

[tex]x=\pm 1+18[/tex]

Now,

[tex]x=1+18[/tex] and [tex]x=-1+18[/tex]

[tex]x=19[/tex] and [tex]x=17[/tex]

Therefore, the correct option is A.

where P is the amount invested at annual rate r for t years.

To find the value of P, we can divide by rt:

  P = I/(rt)

Filling in the given information, we have ...

An architect is making a plan for a new circular playground. If the picture below is the
playground, how much fencing needs to go up to
keep the kids in the circle?

Answers

Answer:

201ft

Step-by-step explanation:

The circumference of a circle is equal to

C=piD

d=64ft

substitute:

c=pi(64)=64pift ft

assume pi=3.14

64pi=64*3.14=200.96ft

round to the nearest whole number:

200.96=201ft

another explanation:

Answer:

Length of the fencing required = 201.06 meters

Step-by-step explanation:

Architect is planning a circular playground with diameter = 64 m

We have to calculate the fencing required to cover this playground.

Length of fencing = circumference of the playground

Since circumference of a circle = π × (Diameter)

                                                   = 64π

                                                   = 201.06 meters

Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.

200.96 meters of fencing needs to go up to keep the kids in the circle. Therefore, option D is the correct answer.

What is circumference of a circle?

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.

Given that, diameter of a circle is 64 meter.

Here, the radius = 64/2

= 32 meter

We know that, the circumference of a circle can be calculated using 2πr.

Now, circumference = 2×3.14×32

= 200.96 meters

Therefore, option D is the correct answer.

hii im sorry to be a burden but could someone please help me with this problem it has to do with the pythagorean theorem :p

Answers

Answer:

Step-by-step explanation:

10 inches

Answer:

68.5 inches

Step-by-step explanation:

The pythagorean theorem is a^2+b^2 = c^2

In this case, a = 60, b = 33, and we are looking for c, so this is how you do it:

60^2 + 33^2 = 3600 + 1089 = 4689

sqrt(4689) = 68.47627326...

Rounded to the nearest tenth is 68.5!
