I don't see any answers provided so, i'm going to add, subtract, multiply, and divide with 6 and -6.

6 + -6 = 0 | Another solution: Any number multiplied by 0

6 - (-6) = 12 | Another Solution: 6 + 6

6 · -6 = -36 | Another Solution: -6 squared

6 / -6 = -1 | Another Solution: -1 x 1

On what interval is the function h(f)=|x+2|-2 increasing ?

VLD [36.1K]

Answer:

The increasing interval is $S=(-2,\infty)$

Step-by-step explanation:

This absolute function has a vertex in x=-2. Now, from this point, the function has a positive slope (increasing), which means for values of x equals to -1,0,1,2,3,...,n.

Therefore the interval will

$S=(-2,\infty)$

The radius of circle A is r cm. The radius of circle B is twice the radius of circle A. What difference between the circumferenc

avanturin [10]

9514 1404 393

Answer:

2πr cm

Step-by-step explanation:

The circumference of a circle of radius r is ...

C = 2πr

For a radius of (r cm), the circumference is ...

A = 2π(r cm) = 2πr cm

For a radius of (2r cm), the circumference is ...

B = 2π(2r cm) = 4πr cm

Then the difference between the circumferences is ...

B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference

Convert 3.2 repenting decimal into a fraction

Olenka [21]

$x =3.\bar{2}\\10x = 32.\bar{2}\\\\ 10x - x = 32.\bar{2} - 3.\bar{2}\\9x = 29\\x = \frac{29}{9}\\\\\\ \boxed{\bf{\frac{32}{9} = 3.\bar{2}}}$

A biker rode 45 miles in 180 minutes. At what speed (in miles per hour) was the biker travelling? A. 4 B. 17 C. 9 D. 12

Anastasy [175]

Answer:

v = 15 miles / hour

Step-by-step explanation:

Given:

Distance covered by biker = s=45 miles

time taken by him = t=180 minutes

TO Find:

speed in miles per hour = v = ?

Solution:

As it is given that the distance covered is 45 miles

and time taken by him is 180 minutes

as one hour have 60 minutes

so time taken by rider = t = 180 /60

= 3 hours

this step is done because we have to find speed in miles per hour

Now

The formula for finding the distance is

distance = speed * time

s = v * t

we have to find v

so dividing both sides by t

$\frac{s}{t} = \frac{v*t}{t}$

it becomes

$v = \frac{s}{t}$

Putting the values

$v = \frac{45}{3}$

solving it gives

v = 15 miles / hour

which is the required speed

in the given options it is not available
