Step-by-step explanation:

hello :

8(e)^2x+1=4

(e)^2x+1=4/8 = 1/2

so : 2x+1 = ln(1/2)

2x = ln(1/2) - 1

x = (ln(1/2) - 1)/2

The solution to the given exponential function is x = [ ln(0.5) - 1]/2

The standard exponential equation is expressed as  y = ab^x

Given the expression

8(e)^2x+1=4

Divide both sides by 8

(e)^2x+1=4/8

(e)^2x+1 = 1/2

Take the ln of both sides

ln(e)^2x+1  ln(1/2)
2x + 1 = ln(0.5)

2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2

Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

Answer:

the value is 0.707

Step-by-step explanation:

The computation is shown below:

Tan (x) = sen (x) ÷ cos (x)

Tan 45° = sen 45° ÷ cos 45° = 1

Now

Sen^2 (x) + cos^2 (x) = 1

Sen^2 (x) + sin^2 (x) = 1 (As sen (x) = u)

2u^2 = 1

u = √1 ÷ √2

= √2 ÷ 2

= 0.707

Hence, the value is 0.707

Answer:

  26, 37, 40, 48

Step-by-step explanation:

Whole numbers between 20 and 50 will have 10s digits in the range 2–5.

When 4 is added to these numbers, we get ...

  2+4 = 6

  3+4 = 7

  4+4 = 8

  5+4 = 9

When 4 is subtracted from these numbers, we get ...

  2-4 = -2

  3 -4 = -1

  4 -4 = 0

  5 -4 = 1

__

The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...

  26, 37, 40, 48

__

We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.

Answer:

Step-by-step explanation:

A landscaping company placed two orders with a nursery. Sam tried to use system of equation to solve the problem.

Let us represent

Cost of bushes = x

Cost of trees = y

The first order was for 13 bushes and 4 trees, and totaled $327.50.

Hence

13x + 4y = 327.5......Equation 1

The second order was for 6 bushes and 2 trees, and totaled $142.96.

Combined both Equations

13x + 4y = 327.5......Equation 1

6x + 2y = 142.96 ........ Equation 2

We solve using Elimination method

We Multiply Equation 1 by 2 and Equation 2 by 4 to Eliminate y

26x + 8y = 655 ..... Equation 3

24x + 8y = 571.84 ..... Equation 4

We substract Equation 4 from Equation 3

2x = 83.16

x = 83.16/2

x = $41.58

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Answer:

[tex] \boxed{y = 10} [/tex]

Step-by-step explanation:

-12 = 6y + 18 – 9y

[Group like terms 6y and -9y]

-12 = (6y – 9y) + 18

[Simplify the expression]

-12 = -3y + 18

[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]

-12 = -3y + 18

–18 –18

-30 = -3y

[Divide by -3 from both sides, division property of equality, to get the variable y by itself]

-30 = -3y

÷(-3) ÷(-3)

10 = y

[Symmetric property of equality, if b = a, then a = b]

y = 10

Step-by-step explanation:

25 min. to get to the library

1-hour story = 60 min.

25 min. to go back home

25 + 25 + 60 = 110 min.

110. min = 1.83333 hrs.

9:15 am + 1.83333 = 10.98333 am

98 - 60 = 38

60 = 1 hr. -----> 60 + 60 = 120 minutes -----> 2 hrs.

Answer:

Lacey need to add 5250 cubic centimeter of water into the fish tank to raise the water level up to the minimum line

Step-by-step explanation:

The bottom dimension of the tank is 75 cm and 35 cm

Water in the tank is 2 cm lower than the minimum line of the tank.

In order to raise the water in tank above the minimum level, we need to add 75 cm * 35 cm * 2 cm

Hence, the total water to be added is

[tex]75 *35 *2 = 5250[/tex] cubic centimeter

Answer:

- 7, - 3, 1, 5

Step-by-step explanation:

Using the recursive rule and a₁ = - 7, then

a₂ = a₁ + 4 = - 7 + 4 = - 3

a₃ = a₂ + 4 = - 3 + 4 = 1

a₄ = a₃ + 4 = 1 + 4 = 5

The first four terms are - 7, - 3, 1, 5

Answer:

12meters

Step-by-step explanation:

Given data

Lenght = 36 meters

Width = 15 meters

The dimension of the diagonal can be gotten via Pythagoras theorem

D^2= L^2+W^2

Substitute

D^2= 36^2+ 15^2

D^2=  1296+225

D^2= 1521

D= √1521

D= 39  meters

Hence the distance while walking on the side is

=36+15

=51 meters

Hence the difference is

=51-39

=12meters
