Answer:

The hierarchy is starting by the parenthesis, followed by any multiplications or divisions and ultimately the additions and subtractions.

Step-by-step explanation:

First operation

1. (1/5+1/2)=(2/10+5/10)= 7/10

2. (7/10)^2= 49/100

4. (49/100) + (3/50)= (49/100 + 6/100) = 55/100

Second operation

We start by the numerator

1. (18 - 4^2 +2) = 18 - 16 +2 = 4

2. 4*2 = 8

Following with denominator

1. 1/4*12= 1/48

When we divide a number by a fraction we have to make use of the following rule (a/b)/(c/d)=(a*d)/(b*c)

Hence: (8)/(1/48) = 8*48 / 1 = 8*48 =384

What are the solutions to the equation <br><img src="https://tex.z-dn.net/?f=2%20%7Cx%20-%202%7C%20%20-%208%20%3D%2020" id="TexF

The solutions of the equation are -12 and 16

Step-by-step explanation:

Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then

x = a
x = -a

∵ 2Ix - 2I - 8 = 20

- At first add 8 to both sides

∴ 2Ix - 2I = 28

- Then divide both sides by 2

∴ Ix - 2I = 14

Now By using the notes above equate x - 2 by 14 and -14

∵ x - 2 = 14

- Add 2 to both sides

∴ x = 16

∵ x - 2 = -14

- Add 2 to both sides

∴ x = -12

The solutions of the equation are -12 and 16

Should my answer be 85=360+12h

pickupchik [31]

Answer:

h = $\frac{- 275}{12}$

Step-by-step explanation:

85 = 360 + 12h

85 - 360 = 360 - 360 + 12h

- 275 = 12h

- 275 ÷ 12 = 12h ÷ 12

h = - 275/12

Find the slope of the tangent line to the curve f(x)=e^(x) at (0.4,1.49)

almond37 [142]

Answer:

1.49

Step-by-step explanation:

In order to find the slope of the tangent line to a given equation, and in a given point, we need to:

1. Find the first derivative of the given function.

2. Evaluate the first derivative function in the given point.

1. Let's find the first derivative of the given function:

The original function is $f(x)=e^{x}$

But remeber that the derivative of $e^{x}$ is $e^{x}$

so, $f'(x)=e^{x}$

2. Let's evaluate the first derivative function in the given point

The given point is (0.4,1.49) so:

$f'(x)=e^{x}$

$f'(0.4)=e^{0.4}$

$f'(x)=1.49$

Notice that the calculated slope of the tangent line is equal to the y-coordinate of the given point because f'(x)=f(x). In conclusion, the slope of the tangent line is equal to 1.49.
