The square root of 1/16 is 1/4=0.25

Step-by-step explanation:

The square root of 1/16 is 1/4.

To find the square root of 1/16, you can take the square root of the numerator and the denominator separately.

√(1/16) = √1 / √16

Since the square root of 1 is 1, and the square root of 16 is 4:

√(1/16) = 1/4

So, the square root of 1/16 is 1/4.

Answer:

Step-by-step explanation:

Since we are given the starting position of the line segment and the length we can simply add or subtract the total length of the line segment to the x or y starting position. This would give us all the possible endpoints that are exactly 5 units away from the starting position in every direction. We can either add or subtract because this would give us the left, right, up, and down directions from the starting position. After making these changes we are left with the following four possible endpoints.

(-1 , -12)

(9 , -12)

(4, -17)

Answer:

0.035°

Step-by-step explanation:

We need to find the value of  [tex]\theta[/tex] for the given expression. So,

[tex]\tan\theta=\dfrac{5\sqrt{20}}{11}[/tex]

or

[tex]\theta=\tan^{-1}\tan\left(\frac{5\sqrt{20}}{11}\right)\\\\=-2.0083\ radian[/tex]

Or we can write as :

[tex]\theta=0.035^{\circ}[/tex]

So, the value of [tex]\theta[/tex] is equal to 0.035°.

Answer:

Step-by-step explanation:

You have a circle with radius r = 3 ft and a 3-by-12 rectangle.

Area of circle = πr² = 9π ft²

Area of rectangle = 3 × 12 = 36 ft²

Total area = 36 + 9π ≈ 64.3 ft²

Perimeter of circle = 2πr = 6π ft

Perimeter of rectangular projections = 18 ft

Total perimeter = 6π +18 ≈ 36.8 ft

Step-by-step explanation:

x1=7, x2= -8

y1=-4, y2=-5

distance CD= √(x2- x1) 2+ (y2-y1)2

= √( -8-7)2 + [-5-(-4)]2

Answer:

[tex]a = -2[/tex]

Step-by-step explanation:

Given

The attached function (graph)

Required

Find a

The given function is quadratic and will be solved using:

[tex]y = ax^2 + bx + c[/tex]

From the attachment:

[tex](x,y) = (-3,4)[/tex]

[tex](x,y) = (-2,2)[/tex]

[tex](x,y) = (-4,2)[/tex]

Substitute these values in [tex]y = ax^2 + bx + c[/tex]

For: [tex](x,y) = (-3,4)[/tex]

[tex]4 = a(-3)^2 + b(-3) + c[/tex]

[tex]4 = 9a -3b + c[/tex]

For: [tex](x,y) = (-2,2)[/tex]

[tex]2 = a(-2)^2 + b(-2) + c[/tex]

[tex]2 = 4a -2b + c[/tex]

For: [tex](x,y) = (-4,2)[/tex]

[tex]2 = a(-4)^2 + b(-4) + c[/tex]

[tex]2 = 16a -4b + c[/tex]

So, we have:

[tex]4 = 9a -3b + c[/tex] --- (1)

[tex]2 = 4a -2b + c[/tex] ---- (2)

[tex]2 = 16a -4b + c[/tex] --- (3)

Make c the subject in (1)

[tex]c = 4 - 9a + 3b[/tex]

Substitute [tex]c = 4 - 9a + 3b[/tex] in (2) and (3)

[tex]2 = 4a -2b + c[/tex]

[tex]2 = 4a -2b + 4 - 9a + 3b[/tex]

Collect Like Terms

[tex]-4 + 2 = 4a - 9a-2b + 3b[/tex]

[tex]-2 = - 5a+b[/tex] --- (4)

[tex]2 = 16a -4b + c[/tex]

[tex]2 = 16a - 4b + 4 - 9a + 3b[/tex]

Collect Like Terms

[tex]2 -4 = 16a - 9a + 3b- 4b[/tex]

[tex]-2 = 7a -b[/tex] --- (5)

Add 4 and 5

[tex]-2 = - 5a+b[/tex]

[tex]-2 = 7a -b[/tex]

--------------------------

[tex]-2 - 2 = -5a + 7a +b - b[/tex]

[tex]-4 = 2a[/tex]

Divide through by 2

[tex]-2 = a[/tex]

[tex]a = -2[/tex]

Measurement is the numerical quantification of the attributes of an object or event, which can be used to compare with other objects or events.

Measurement is used to compare or determine the relation of a quantity, physical or not, with a certain  numerical value.

We have to determine, which is used to compare or determine the relation of a quantity, physical or not, with a certain  numerical value

According to the question,

The process of measurement is required to measure or compare physical quantities in day-to-day life.

Thus, to measure each of the standard quantities, we choose certain units for them that are accepted worldwide.

Other similar quantities can also be expressed in terms of these units and can be measured accordingly.

The physical quantities are measured in terms of the unit and are known as a standard of that physical quantity.

The length of the foot, the width of a finger, and the distance between two different places were commonly measured by different units of measurements.

For unique measurement properties, scientists accepted standard units of measurement all over the world.

Hence, Measurement is used to compare or determine the relation of a quantity, physical or not, with a certain numerical value.

The answer is below

Step-by-step explanation:

Show that f(x) f(y) = f(x+y)

From trigonometric:

sin(x + y) = sinxcosy + cosxsiny

sin(x - y) = sinxcosy - cosxsiny

cos(x + y) = cosxcosy - sinxsiny

cos(x - y) = cosxcosy + sinxsiny

Theodore get 6 quarters in Prize.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let p the number of pennies, d be the number of dimes, n be the number of nickels and q be number of quarters.

So, the expressions are

p = 3d                

n = d+1              

   = 5(d+1)

d = 10d

and, q = 2d              

           = 25 (2d)                    

and, the total is = $209

                          = 209

Then,

3d + 5(d+ 1)  + 10d  +25 ( 2d) = 209

68d + 5 = 209

d = 3                          

Thus, the number of quarters = 2d = 6 quarters.
