Answer:

f(0.1) = [tex]i \pi[/tex]

Step-by-step explanation:

Plug x = 0.1.

Therefore f(0.1) = ln (log (0.1)).

0.1 = 10^(-1), and by the definition of log, log 0.1 = -1.

Now f(0.1) = ln (-1).

By Euler's identity, e^(i pi) = -1.

So ln (-1) would be i pi.

f(0.1) = [tex]i \pi[/tex]

Answer:

C = pi * d calculates the circumference (distance around the outside of the circle). D in the formula refers to the diameter which is the width of the circle. The formula for the area of a circle is A = pi * r * r where r is the radius (diameter / 2).

Answer:

C=13

Step-by-step explanation:

Ok, so those to angles are going to equal 90*.

First, you wan to setup your equation,

(2c-4) + (5c+3) = 90

now you want to add the angles

7c -1 = 90

isolate the variable .

Add 1 to both sides

7c=91

Now divide 7 from both sides

c=13.

To check our work we will plug in for C.

2(13)-4 + 5(13)+3=90

26 - 4 + 65 + 3=90

90=90

Step-by-step explanation:

Step 1: Define

-98 = 7t

Step 2: Solve for t

Divide 7 on both sides: -14 = t

Rewrite: t = -14

Step 3: Check

Plug in t into the original equation to verify it's a solution.

Substitute in t: -98 = 7(-14)

Multiply: -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

Answer:

Side TV = 16

Step-by-step explanation:

WX is half the value of TV

to solve we have to set up an equation

21-5x=10x-2

because side WX is only have of side TV we have to multiple its side by 2 so now we have

21-5x=20x-4

step 1 add 4 to each side

25-5x=20x

step 2 add 5x to each side

25=25x

step 3 divide each side by 25

x=1

then we plug in x as 1 for side TV and get

21-5 which is equal to 16

Answer:

a ≈ 13.1

c ≈ 13.8

Step-by-step explanation:

set up proportions based on corresponding sides:

17 = 13

a       10

13a = 170

a ≈ 13.1

18 = c

17      13

17c = 234

c ≈ 13.8

Answer:

$12

Step-by-step explanation:

amount of tax = $0.72

percent of tax= 6%

Let the original cost be x

so that

6% of x= 0.72

solve for x

6/100*x= 0.72

0.06x= 0.72

divide both sides by 0.06

x= 0.72/0.06

x=$12

Hence the cost is $12

Answer:

I would say Right, Isosceles.

Step-by-step explanation:

Answer:

1. y = 1/3x - 1

2. y = 2/5x

3. y = x + 8

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + c

where m is the slope and c is the y-intercept

So, we have the following based on the supplied values;

1. y = 1/3x - 1

2. y = 2/5x

3. y = x + 8

Answer:

d) 20

Step-by-step explanation:

To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

Answer:

6 miles

Step-by-step explanation:

At a speed of 8 2/5 miles per hour, you can run a distance of 6 miles

Speed = distance / time taken

8 2/5 = x ÷ 5/7

42/5 = x ÷ 5/7

cross product

42/5 × 5/7 = x

x = (42×5) / (5×7)

= 210/35

= 6 miles

Therefore, you can run a distance of 6 miles at a speed of 8 2/5 miles per hour
