Step-by-step explanation:

I've just replaced letter A with x so that I can make it easier for me to get the value of x and after adding 54 + 82 I got 136 and when I transferred it to the other side I subtracted it from 180 because it had a positive sign before it and if it is carried out the other side it becomes a negative which means I should subtract hope you got me.

in short once a positive number is carried to the other side I mean past the equals sign then it changes to negative hope it helps

Answer:

Center: (0, -2)

radius: 8

Explanation:

Given equation: x² + (y + 2)² = 64

The Circle Formula:

(x - h)² + (y - k)² = r²

where (h, k) are points of center. r denotes radius

So rewrite the equation in circle formula:

x² +(y + 2)² = 64

(x- 0)² +(y + 2)² = 8²

Identify followings:

h = 0, k = -2, radius = 8

Answer:

  resistance must quadruple

Step-by-step explanation:

You want to know the change in resistance required to quadruple the amount of heat if heat is proportional to the square of voltage, inversely proportional to resistance, and the voltage is quadrupled.

Let H represent the heat generated for voltage V and resistance R. We want to find R, the new resistance required, when V is replaced by 4V, and H is replaced by 4H.

  H = V²/R

  4H = (4V)²/R'

  4(V²/R) = 16V²/R'

  R' = (16/4)R . . . . . . . multiply by RR'/(4V²)

  R' = 4R

The resistance must quadruple if the amount of heat is to be quadrupled.

Step-by-step explanation:

Y = 3x - 10

So, 4x + 5y = 7

= 4x + 5(3x - 10) = 7

= 4x + 15x - 50 = 7

= 19x - 50 = 7

= 19x = 7 +50

= 19x = 57

= X = 57/19

X = 3

Answer:

9

Step-by-step explanation:

Because 40% hit the bullseye, we can subtract 40% from 100% meaning 60% did not hit the bullseye.

We can then convert 60% into the decimal .6 and multiply it by 15.

15 x .6 = 9

Answer:

6.15 × 10⁵

Step-by-step explanation:

When converting a number of scientific notation, we need to move the decimal point until the number is greater than 1 and less than 10, then multiply this by 10 to the power of the number of places we moved the decimal point (negative when moving it forwards, positive when moving it backwards).

Therefore, 615000 = 6.15 × 10⁵

The experimental probability of the arrow stopping on Section 2 will be [tex]\rm \frac{3}{8}[/tex]. is the ratio of the favorable event to the total number of events.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

No of arrows given in the different section ;

Section 1=18

Section 2=30

Section 3=32

The probability that the arrow stopping on Section 2 is found as;

[tex]\rm P = \frac{Favourable \ outcomes }{Total \ outcomes } \\\\\ P= \frac{30}{18+30+32} \\\\ P=\frac{30}{80}\\\\ P= \frac{3}{8}[/tex]

Hence, the experimental probability of the arrow stopping on Section 2 will be [tex]\rm \frac{3}{8}[/tex].

Answer:

x = 115°

Step-by-step explanation:

Given angle y = 65°

Find angle x

=> x + y = 180

=> x + 65° = 180

=> x = 180 - 65

=> x = 115°

Answer:

what is the figure so i can awnser iit

Step-by-step explanation:

?

Answer:

One year: Between $132,000 and $480,000.

20 years: Between $2,640,000 and $9,600,000.

60 years: Between $7,920,000 and $28,800,000.

Step-by-step explanation:

If it makes between 11,000 and 40,000 a month, you should take both values and average them or make an estimate. Since there are 12 months in a year, 11,000*12 = $132,000 minimum, 40,000*12 = $480,000 maximum.

In 20 years, 132,000*20= $2,640,000 minimum, 480,000*20 = $9,600,000 maximum.

In 60 years, 2,640,000*3 = $7,920,000 minimum, 9,600,000*3 = $28,800,000 maximum.

If you want to be more specific, you need to find the average number of times you make certain amounts of money per month to find how likely it is to make a certain amount.

Step-by-step explanation:

The limit of x times cosine of the quantity 5 times x all over sine of the quantity 5 times x as x approaches 0 is determined as ¹/₅.

The limit of the function is determined as follows;

[tex]\lim_{x \to 0} \ \frac{sinx}{x} = 1\\\\ \lim_{x \to 0} \ \frac{x(cos5x)}{sin5x}[/tex]

The derivative of the function;

[tex]\frac{xcos(5x)}{sin5x} = \frac{-5x(sin(5x)) + cos(5x)}{5cos(5x)}\\\\= \frac{-5x(sin(5x))}{5cos(5x)} + \frac{cos(5x)}{5cos(5x)} \\\\ \lim_{x \to 0} \\\\= 0 + \frac{1}{5} = \frac{1}{5}[/tex]

Thus, the limit of x times cosine of the quantity 5 times x all over sine of the quantity 5 times x as x approaches 0 is determined as ¹/₅.

The measure of the third angle in the triangle is 104 degrees

Let the three angles in the triangle be x, y and z.

Such that:

x = 51

y = 25

The sum of angles in a triangle is 180 degrees.

So, we have:

x + y  + z = 180

Substitute known values

51 + 25 + z = 180

Evaluate the sum

76 + z = 180

Subtract 76 from both sides

z = 104

Hence, the measure of the third angle is 104 degrees

Now

AB

Answer:

24.03 units (nearest hundredth)

Step-by-step explanation:

The distance between B and A is:  AB = AH + HB

We have been given AH, so we just need to find the measure of HB.

First, find the angle AOH using tan trig ratio:

[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]

where:

Given:

[tex]\implies \sf \tan(\angle AOH)=\dfrac{8}{19.8}[/tex]

[tex]\implies \sf \angle AOH = 22.00069835^{\circ}[/tex]

   ∠BOA = ∠BOH + ∠AOH

⇒ ∠BOH = ∠BOA - ∠AOH

⇒ ∠BOH = 61° - 22.00069835°

               = 38.99930165°

Now we can find HB by again using the tan trig ratio:

Given:

Substituting given values:

[tex]\implies \sf \tan(38.99930165^{\circ})=\dfrac{HB}{19.80}[/tex]

[tex]\implies \sf HB=19.80 \tan(38.99930165^{\circ})[/tex]

[tex]\implies \sf HB=16.03332427[/tex]

Therefore:

   AB = AH + BH

⇒ AB = 8 + 16.03332427

         = 24.03 units (nearest hundredth)
