Note: Your equation seems a little unclear. But, I am assuming that your equation is:

[tex]e^x\:+\:e^{-1}=\:2[/tex]

Because my solution would still clear your concept about this topic, no matter what the question is.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]e^x\:+\:e^{-1}=\:2[/tex]

subtract [tex]e^{-1}[/tex] from both sides

[tex]e^x+e^{-1}-e^{-1}=2-e^{-1}[/tex]

[tex]e^x=2-\frac{1}{e}[/tex]

[tex]\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)[/tex] ∵ [tex]\:\:\ln \left(e\right)=1[/tex]

[tex]x=\ln \:\left(2-\frac{1}{e}\right)[/tex]

[tex]x=0.5[/tex]

H. 100°
J. 108°
K. 116°

Answers

Answer:

J. 108°

Step-by-step explanation:

m<EDF = 180 - 148 = 32° (angles on a straight)

m<EFD = 180 - 140 = 40°(Angles in a straight line)

m<DEF = 180 - (m<EDF + m<EFD) (sum of triangle)

m<DEF = 180 - (32 + 40)

m<DEF = 180 - 72

m<DEF = 108°

Answer:

6⁻¹

Step-by-step explanation:

6⁻⁶ = [tex]\frac{1}{6^6}[/tex] and 6⁻⁵ = [tex]\frac{1}{6^5}[/tex]

[tex]\frac{1}{6^6} * \frac{6^5}{1} = \frac{6^5}{6^6} = \frac{6^0}{6^1} = \frac{1}{6}[/tex] ** top & bottom same base 6, subtract exponent

[tex]\frac{1}{6}[/tex] = 6⁻¹

A cone has height h and a base with radius r. You want to change the cone so its

volume is halved. What is the new height if you only change the height? What is the

new radius if you only change the radius? Explain.

Answers

9514 1404 393

Answer:

a) h/2

b) r/√2 = (r√2)/2

Step-by-step explanation:

a) The volume of a cone is proportional to height. If the volume is halved, then the height will be halved.

The new height will be h/2.

b) The volume is proportional to the square of the radius. If the volume is halved, the square of the radius is halved. The new radius will be ...

(r')² = r²/2

r' = r/√2 = (r√2)/2 . . . radius of half-volume cone

An architect makes 14455.32 a year. If they get paid weekly, how much do they get each paycheck? Round to the nearest cent

Answers

Answer: $277.99

Step-by-step explanation:

There are 52 weeks in a year. Assuming the architect would get paid every week, you would divide their salary by 52.

14,455.32/52 = 277.9869

Rounding to two decimal places, the answer would be $277.99.

Answer:

301.15

Step-by-step explanation:

First multiply 12 by 4. 12 months 4 weeks in each. You get 48 then you divide 14455.32 and you get 301.15.

A farmer has a rectangular plot of land. There is a bother identical plot of land 100 yards east and 100 yards north. Find the combined area of the two plots of land

Answers

Answer:

Step-by-step explanation:

Area of a rectangular plot = Length × width

With the aid of the diagram attached below.

For plot 1:

The area = ( 60 - 20 ) × ( 80 - 20 )

Area = 40 × 60

Area = 2400 sq yard

For plot 2:

Area = (160 - 120 ) × ( 180 - 120 )

Area = 40 × 60

Area = 2400 sq yard

Therefore, the combined area of the two plots of land = 2400 + 2400

= 4800 square yards

Which inequality has the graph shown below?
Answers above ^

Answers

Answer:

The inequality the graph has shown is y < 2x - 3 ⇒ C

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope of the lineb is the y-intercept

From the given figure

∵ The line drawn is a dashed line

→ That means the sign of inequality without the equal sign

∴ The sign of the inequality is without the equal sign

∵ The shaded area is under the line

→ That means the sign of the inequality is smaller than

∴ The sign of the inequality is <

∵ The line intersects the y-axis at point (0, -3)

→ That means the y-intercept is -3

∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)

∵ There is only one answer has sigh < and y-intercept -3

∴ The inequality the graph has shown is y < 2x - 3
