Perimeter = 56
Hypo = 25
So 56-25 = 31 (for two side)
for one side = 31/2 = 15.5

so area = 1/2 x base x height

no change

We've now found that there was (surprisingly) no change in the rectangle's area, despite changing its size.

"My new phone cost a fortune,"said Amy. " Mine costs twice as much," said Jill. If together, the two phones cost $575.25, how mu
Naddik [55]

Answer:

Cost of Amy's Phone= $191.75

Cost of Jill's phone = $191.75*2= $383.5

Step-by-step explanation:

let Amy's phone cost be A

Jill's phone cost = 2A

A/Q-

A +2A = $575.25

3A= $575.25

A=$575.25/3

A= $191.75

then,

Cost of Amy's Phone= $191.75

Cost of Jill's phone= $191.75*2= $383.5

How do I solve part b?
Minchanka [31]

Answer:

x \approx 1.4

Step-by-step explanation:

This problem gives one the following equation to model the graph of a line: (y=x^2-2). The problem asks one to find the value of (x) when (y=0). Rather than using the graph, an easier way to solve this problem is to substitute (0) in for the value of (y) and then solve for (x) using inverse operations.

y=x^2-2\\

Substitute,

0=x^2-2

Inverse operations,

0=x^2-2\\\\2=x^2\\\\\sqrt{2}=x

Round:

x \approx 1.4

As one can see on the graph, this result is very close to the value at which the graph intersects the (x) axis. Thus, one can conclude that (x) does indeed approximately equal (1.4)

Does anyone know the area and perimeter for this??​
Oksi-84 [34.3K]

Answer:

AREA= 198 mm

PERIMETER = 57mm

Step-by-step explanation:

1: to take out the perimeter , add all the sides i. e. 12+14+18+13=57

2: to take out the area use formula B*H i. e. base *height - area of a parallelogram

B=18

H=11

18*11=198

this is the area

What is the end behavior of the function f of x equals negative 4 times the cube root of x?
vampirchik [111]

The function f(x) = 4\sqrt[3]{x} is a cube root function

The function end behavior is:

\quad \mathrm{as}\:x\to \:+\infty \:,\:f\left(x\right)\to \:+\infty \:,\:\:\mathrm{and\:as}\:x\to \:-\infty \:,\:f\left(x\right)\to \:+\infty

<h3>How to determine the end behavior?</h3>

The equation of the function is given as:

f(x) = 4\sqrt[3]{x}

To determine the end behavior, we plot the graph of the function f(x).

From the attached graph of the function, we can see that:

As x approaches infinity, the function f(x) approaches infinity, and vice versa

Hence, the function end behavior is:

\quad \mathrm{as}\:x\to \:+\infty \:,\:f\left(x\right)\to \:+\infty \:,\:\:\mathrm{and\:as}\:x\to \:-\infty \:,\:f\left(x\right)\to \:+\infty
