The correct matches are:

32 corresponds to log₂(x) = 5

3 corresponds to log₃(x) = 1

1,000 corresponds to log₁₀ (x) = 3

625 corresponds to log₅(x) = 4

16 corresponds to log₄(x) = 2

What is Logarithm?

A logarithm is a mathematical function that represents the exponent to which a specific base must be raised to obtain a given number. In other words, it is the inverse operation of exponentiation.

The logarithm of a number x to a given base b is denoted as log_b(x), where b is the base and x is the number. It represents the power to which the base must be raised to obtain the value x.

The logarithmic equations and their corresponding x-values are as follows:

log₂(x) = 5 → x = 32

log₃(x) = 1 → x = 3

log₁₀(x) = 3 → x = 1,000

log₅(x) = 4 → x = 625

log₄(x) = 2 → x = 16

So, the correct matches are:

32 corresponds to log₂(x) = 5

3 corresponds to log₃(x) = 1

1,000 corresponds to log₁₀ (x) = 3

625 corresponds to log₅(x) = 4

16 corresponds to log₄(x) = 2

if x+y= -10 and x-y=2 what is the value of x

Answers

Answer:

X+Y=10, X-Y=2, what is X, Y?

Answer: x=6 and y=4

Explanation:

Given:

x+y=10 ⟶(i)

x−y=2 ⟶(ii)

From equation (ii) ,

x=2+y

Put value of x in equation (i) ,

2+y+y=10

2+2y=10

2(1+y)=10

1+y=102

1+y=5

y=5−1

y=4

Put value of y in equation (ii) ,

x−4=2

x=2+4

x=6

x + y = 10 → Eq A

x – y = 2 → Eq B

Now we will take out the expression of x from Eq A.

x + y = 10 Eq A

x = 10 – y → Expression of x

Now put the expression of x in Eq B.

x – y = 2

( 10 – y ) – y = 2

10 – 2y = 2

10 – 2 = 2y

8 = 2y

y = 8 / 2

y = 4

Now put the value of y in expression of x.

x = 10 – y

x = 10 – 4

x = 6

So, x = 6 and y = 4.

Thank you.

Hope it helps and you like it

x + y = - 10 (equation 1)

x - y = 2 (equation 2)

using equation 2 we get x = 2 + y

putting the value of x in equation 1 we get :

(2 + y) + y = - 10

2 y = -10-2

2 y = -12

y = -6

put the value of y in any equation

to get the value of x

x - y = 2

x - (-6) = 2

x + 6 = 2

x = -4

Rebecca is saving money to purchase a laptop which cost $1,099.51 she has already saved $354.20 and plans to continue saving $50.60 per week which inequality could be used to find W the number of weeks of Rebecca must save in order to purchase a laptop ​

Answers

Answer:

745.31+50.60w=1,099.51

W=7

Step-by-step explanation:

1st subtract 1099.51 from 354.20

2nd use your answer which is 745.31 and add that with how much she plans on saving for how ever long

3d to find out how many weeks which is 50.60*w you need to first minus 745.31 from both sides

4th so 745.31- 745.31 and 1099.51-745.31 =354.2 or .20

5th divide 354.2 by 50.60 =7

So overall w= 7


In the morning, the trip odometer in Mr. Chin's car read 47 miles. At the end of the day, the trip odometer read 114 miles. How
many miles did Mr. Chin drive that day?

miles travelled:

final reading - initial reading114 - 4767 miles

Answer:

67 miles

Step-by-step explanation:

An odometer measures the distance traveled by a vehicle.

To calculate the number of miles Mr Chin drove that day, subtract the reading of the odometer at the start of the day from the reading of the odometer at the end of the day.

Given information:

Starting odometer reading = 47 milesEnding odometer reading = 114 miles

⇒ Number of miles driven = 114 - 47

An equation for a toy boat is bobbing on the water is in the sinusoidal form which we can write as, D(t) =  0.2 sin2t +1

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, D(t) =  acos2t +b

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given information,

Equation  of bobbing, D(t) =  a sinbt + d

By graph we can say that it is compressed two times,

So, value of b will be, 2

At t =0, height from the floor is 1 m

1  =  a sin(2×0) + d

d = 0

At t =π/4, height from the floor is 1.2 m

1.2 =  a sin(2×π/4) + 1

a = 0.2

By graph we can say that it is compressed two times,

So, value of b will be 2

Hence, An  equation is  D(t) =  0.2 sin2t +1

B. 2i√3

C. 12i

D. -2√3

E. -12i

Answers

Answer:

Step-by-step explanation:

Remark

√-12  

The square root of -12 must have an i in it somewhere. If it does not, then the minus sign stays under the root sign. If you take the root of -1 you get i, and that is outside √ sign.

Solution

A is incorrect. i is on the outside of the root sign.

B is the answer.

C does not seem to take the square root of anything except -1 so it is incorrect.

D Has no i anywhere and the -1 is incorrectly placed. D is wrong

E is just wrong. The minus should disappear once the square root of -1 is taken. 12 has a root that has not been declared.

Assuming the Actual production and sales amounted to 2,200 units.The sales and variable cost is:2400 F; $1,440 UF.

Sales and variable cost volume variances

a. Sales and variable cost volume variances

Sales =(Actual units sold -Budgeted units sold)× Budgeted price per unit

Sales=(2200-2000)×$12.00 per unit

Sales=26,400-$24,000

Sales=2400 F

Variable=(Actual units sold -Budgeted units sold)× Budgeted price per unit

Variable=(2200-2000)×$7.20 per unit

Variable=$15,840-$14,400

Variable=$1,440 UF

b. Sales=2400 F

Variable=$1,440 UF

d.  Fixed cost

Fixed manufacturing cost $3,600

Fixed selling and administrative cost $1,200

e.                                                    Master budget   Flexible budget

Fixed manufacturing cost                     $3,600                  $3,600

Fixed selling and administrative cost $1,200                   $1,200

Tota fixed cost                                      $4,800                 $4,800

Cost per units                                        $2.4                       $2.18
