What is the radius of a circle with a diameter of 100

Answer:

[tex]\angle FCB[/tex]

Step-by-step explanation:

Supplementary angles are angles that sum to [tex]180^{\circ}[/tex]. In this case, [tex]\angle FCB[/tex] is supplementary to [tex]\angle DCF[/tex] since they add up to the angle of a straight line which is [tex]180^{\circ}[/tex].

Answer:

-0.9

Step-by-step explanation:

0.6(x+2)=0.55(2x+3)

Use the distributive property to multiply 0.6 by x+2.

0.6x+1.2=0.55(2x+3)

Use the distributive property to multiply 0.55 by 2x+3.

0.6x+1.2=1.1x+1.65

Subtract 1.1x from both sides.

0.6x+1.2−1.1x=1.65

Combine 0.6x and −1.1x to get −0.5x.

−0.5x+1.2=1.65

Subtract 1.2 from both sides.

−0.5x=1.65−1.2

Subtract 1.2 from 1.65 to get 0.45.

−0.5x=0.45

Divide both sides by −0.5.

x= 0.45/−0.5

x= -0.9

Answer:

$15

Step-by-step explanation:

let the hourly rate of pay for Ben  = B

let the hourly rate of pay for Judy  = J

Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;

              4J + B = 75 ----- i

Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120

               2J + 6B  = 120 --- ii

Now, we should solve the expression;

   Multiply equation ii by 2 and equation i by 1;

            4J + B = 75 ----- i    x 1  ;    4J + B  = 75          -- iii

            2J + 6B  = 120 --- ii  x 2 ;   4J + 12B  = 240    ---iv

Now,

 equation iv - iii;

                   11B  = 165

                      B  = $15

So, solving for J;

          4J + B = 75

         4J + 15  = 75

          4J  = 75 - 15  = 60

          J  = $15

Answer:

w = 59°

Step-by-step explanation:

sides AC and BC are congruent thus Δ ABC is isosceles, then the 2 base angles are congruent, that is

∠ A = ∠ B , so

w = [tex]\frac{180-62}{2}[/tex] = [tex]\frac{118}{2}[/tex] = 59°

Answer:

The description of the set is [tex]A = \{s\in \mathbb{C}|\|s\| = 2\}[/tex].

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

[tex]s = a+i\, b[/tex], [tex]a,b \in \mathbb{R}[/tex] (1)

Where [tex]i = \sqrt{-1}[/tex].

In addition, the distance from the origin is defined by the following Pythagorean identity:

[tex]\|s\| = \sqrt{a^{2}+b^{2}}[/tex] (2)

The following condition must be satisfied:

[tex]\|s\| = 2[/tex]

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

[tex]A = \{s\in \mathbb{C}|\|s\| = 2\}[/tex] (3)

The set of all complex numbers that are at a distance of 2 units from the origin is [tex]\{z\in \mathbb{C} :\text{ }|z|=2\}[/tex]

A complex number, written in rectangular form is

[tex]z=a+ib\\a,b\in \mathbb{R}[/tex]

The distance of a complex number from the origin (the modulus of the complex number, denoted by [tex]|z|[/tex]) is given by the formula

[tex]|z|=\sqrt{a^2+b^2}[/tex]

Since we want all the complex numbers to be at the distance of 2 units from the origin, they must satisfy

[tex]|z|=2[/tex]

thus, the set we are looking for is

[tex]D=\{z\in \mathbb{C} :\text{ }|z|=2\}[/tex]

where [tex]\mathbb{C}[/tex] is the set of all complex numbers

Answer:

commercial =  9

movie = 5

Step-by-step explanation:

Step one:

let the number of commercials be x and movies be y

so

40x+130y=1010-------------1

since there are a total of 14 commercials and movies combined

x+y=14--------------2

Hence the systems of equation is

40x+130y=1010------1

x+y=14-------------------2

Step two:

from equation 2

x=14-y

substui]te the value of x in  equation 1

40(14-y)+130y=1010

560-40y+130y=1010

collect like terms

130y-40y=1010-560

90y=450

divide both sides by 90

y=450/90

y=5

movies is 90

put y=5 in equation 2

x+5=14

x=14-5

x= 9

commercial is 9 in numbers

and movie is 5

Answer:

a. 90 pizzas

b. 12% decrease

Step-by-step explanation:

To receive a bonus, there must be 20% increase in the number of pizzas

Thus;

20% of 75 = 20/100 * 75 = 1500/100 = 15

So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90

So now, we have 66 pizza sold today;

We can see that there was a decrease from 75

Percentage decrease will be;

(new value - old value)old value * 100%

= (66-75)/75 * 100%

= -9/75 * 100%

= -0.12 * 100% = -12%

This shows a 12% decrease

Answer:

Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]

Equations with no solution:

[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]

Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Step-by-step explanation:

We will solve each equation to see if it has one solution, no solution or infinite many solutions.

An equation where the value of variable can be found has one solution.

An equation with no solution has both sides different.

An equation with infinite solution will have both sides equal after solution(number)

So,

Equation 1:

5(x-2) = 5x-7

[tex]5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3[/tex]

As both sides are not equal, equation has no solution.

Equation 2:

[tex]-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\[/tex]

As both sides are equal the equation has infinite many solutions.

Equation 3:

[tex]-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3[/tex]

As x=3, the equation has only one solution.

Equation 4:

[tex]6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11[/tex]

The equation has no solution.

Hence,

Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]

Equations with no solution:

[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]

Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

I took it on edg 2020

The Complex Alternative form to the expression (5[cos(π/4) + i sin(π/4)])^3 is given as: (Option C).

A complex number of equations will take the form x + yi, where x and y are real numbers and i is an indeterminate that satisfies the rule i² = -1.

Hence, the solution to the above is given as follows:

Step 1 - Ludooph's number pi is given as:

π ≈ 3.14159265

Step 2 - Divide  3.14159265/4

= 0.78539816

Step 3

Cos (0.78539816)

= 0.70710678

It is assumed that the trigonometric angle argument is in radians.

Step 4

Divide: 3.14159265 / 4

= 0.78539816

Step 5 - find the Sin of the result of step 4

sin(0.78539816)

= 0.70710678

It is assumed that the trigonometric angle argument is in radians.

Step 6

Multiply i by the result of Step No 5

=  i * 0.70710678

= 0.7071068i

Step 7 - Add the result of step no. 3 and the result of step number 6

= 0.70710678 + 0.7071068i

= 0.7071068+0.7071068i

Step 8 Multiply 5 by the result of step 7

= 5 * (0.7071068+0.7071068i)

= 5 * 0.70710678118655 + 5 * 0.70710678118655i

= 3.53553391+3.53553391i

= 3.53553391 +i(3.53553391)

= 3.5355339+3.5355339i

Step 9 - Exponentiate the results of Step 8 to the third power:

= (3.5355339+3.5355339i) ^ 3

= (5 × ei π/4)3 = 53 × ei 3 × π/4

= 125 × ei 3π/4

= -88.3883476+88.3883476i

If left in the Alternate Complex form, we have:
125[cos(3π/4) + i sin(3π/4)]
