Answer:  5.816 × 10²

581.6 in scientific notation is 5.816 × 10²

Answer:

r=−1/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(r−10)=−51

(5)(r)+(5)(−10)=−51(Distribute)

5r+−50=−51

5r−50=−51

Step 2: Add 50 to both sides.

5r−50+50=−51+50

5r=−1Step 3: Divide both sides by 5.

5r/5=−1/5

r=−1/5

Answer:

Step-by-step explanation:

5(r - 10) = -51

5r - 50 = -51

5r = -51 + 50

5r = -1

r = - ¹/₅ or 0.2

Answer:

Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.

It means the number of wedding invitations they can send based on their budget

Step-by-step explanation:

To determine the zero of the function, we simply set the dependent variable ( m in this case) to zero.

Thus, mathematically;

0 = 50-1.25w

1.25w = 50

w = 50/1.25

w = 40

So what does this mean in the context of the situation?

What it means is that the total number of people they would be able to send the mail to based on their budget is 40

Answer:

The zero of the function is at

40. This represents that after mailing 40 wedding invitations, Moesha and Keyon will $ 0 left.

Answer: Find the the height and length of the triangle. I'm not sure what it would be but then use a1  + a2 to find the area

Answer:

Formula of triangle: A = 1/2 x b x h

Step-by-step explanation:

Solve the base of the triangle by solving the distance between points (-2,0) and (f, -5) in units, and then do the same for height: find distance between points (-2, 6) and (-2, 0). Once you find the distance, input value of base and height into the formula and solve to get the area!

Answer:

Ratio of number of boys to girls= 2:3

Ratio of number of boys to girls to total number of children= 2:3:5

Step-by-step explanation:

42 boys and 63 girls took part in an art competition

The ratio of the number of boys to the number of girls can be calculated as follows

= 42/63

= 2:3

The ratio of the number of boys to girls to total number of children can be calculated as follows

= 42/63/105

= 2:3:5

Step-by-step explanation:

Answer:

324 and 144

Step-by-step explanation:

We require

a₁, a₂, a₃, a₄

where a₂ and a₃ are the required geometric means

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 729 and a₄ = 64, thus

729(r³) = 64 ( divide both sides by 729 )

r³ = [tex]\frac{64}{729}[/tex] ( take the cube root of both sides )

r = [tex]\sqrt[3]{\frac{64}{729} }[/tex] = [tex]\frac{4}{9}[/tex] , then

a₂ = 729 × [tex]\frac{4}{9}[/tex] = 81 × 4 = 324

a₃ = 324 × [tex]\frac{4}{9}[/tex] = 36 × 4 = 144

Thus

729, 324, 144, 64

Calculating the Least Common Multiple

3.1    Find the Least Common Multiple

     The left denominator is :       16

     The right denominator is :       12

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

2 4 2 4

3 0 1 1

Product of all

Prime Factors  16 12 48

     Least Common Multiple:

     48

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 3

  Right_M = L.C.M / R_Deno = 4

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      117 • 3

  ——————————————————  =   ———————

        L.C.M               48  

  R. Mult. • R. Num.      47 • 4

  ——————————————————  =   ——————

        L.C.M               48  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

117 • 3 - (47 • 4)     163

——————————————————  =  ———

        48             48

Final result :

 163          

 ——— = 3.39583

Answer:

sorry for my writing

i tried to do as fast as possible

Answer:

Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.

The independent variable is: "the cost of the smart phone"

Step-by-step explanation:

An independent variable is simply one that doesn't depend on other variables measured in the same sentence.

Now, in the question, we are told that the smart phone device has a fixed cost. This means that the cost doesn't depend on any other variable mentioned in the sentence.

Thus, the independent variable is: "the cost of the smart phone"

Answer:

-3

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The interval at which the graph of y = cos x is strictly increasing is

π < x < 2π.

Option D is the correct answer.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

y = cos x

Cos π = cos (π/2 + π/2) = Sin π/2 = 1

Cos 2π = Cos (π + π) = - Cos π = - Cos (π/2 + π/2) = - Sin π/2 = -1

We see that,

y = Cos x is strictly increasing from -1 to 1.

Thus,

y = cos x is strictly increasing from π < x  < 2π.
