A square has an area of 100 in2. What is the perimeter of the square?

1 answer:

7 0

40 in2.

To find the area you multiply the width by length so you would have to find what multiplied by what would equal 100. This gives you the answer of 10. To find the perimeter you add up all the sides and because a square has 4 sides you would add 10+10+10+10 which equals 40. Hope this helped!

Write the equation of a piecewise function with a jump discontinuity at x =3. Then, determine which step of the 3-step test for

seraphim [82]

Answer:

Here's a possible example:

Step-by-step explanation:

$f(x) =\begin{cases} x & \quad x < 3\\x+3 & \quad x \geq 3\\\end{cases}$

Each piece is linear, so the pieces are continuous by themselves.

We need consider only the point at which the pieces meet (x = 3).

$\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) = \lim_{x \longrightarrow 3^{-}} x = 3\\\\\displaystyle \lim_{x \longrightarrow 3^{+}} f(x) = \lim_{x \longrightarrow 3^{+}} x+3 = 6\\\\f(3) = x + 3 = 6\\\\\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) \neq f(3)$

The left-hand limit does not equal ƒ(x), so there is a jump discontinuity at x =3.

Solve the system of equations 4x+5y=-1 and -5x-8y=10 by combining the equations.

Nimfa-mama [501]

The solution of the equation are as follows:

x = 6 and y = -5

<h3 />

<h3>How to solve the system of equation?</h3>

4x + 5y = -1

-5x - 8y = 10

Therefore,

20x + 25y = -5

-20x - 32y = 40

-7y = 35

y = -5

Hence,

4x + 5(-5) = -1

4x - 25 = -1

4x = -1 + 25

4x = 24

x = 24 / 4

x = 6

PLEASE MATH HELP 20 points PLEASE!!!!

blsea [12.9K]

Y = 18( 0.58) ^t

It would be written as :
Y = 18(0.11) ^ (t/4)
Y = 18 (0.11 ^ (1/4)) ^ t
But
0.11 ^ (1/4) = 0.5759

Plug the value

Y = 18 (0.5759) ^ t

Two decimal point :

Y = 18 (0.58) ^ t

Shuan rides his bike at a speed of 19 mph how far in miles is shuan travel in 25 minutes

irga5000 [103]

Answer:

7.92 miles (aprox.)

Step-by-step explanation:

1 hour = 60 minutes

19mph = 19miles/hour = 19miles/60 minutes

Proportions:

19 miles ⇔ 60 minutes

W miles ⇔ 25 minutes

W = 19*25/60

W = 7.92 miles (aprox)
