Answer:

8.04 units

Step-by-step explanation:

By Pythagoras Theorem:

{x}^{2}  =  \bigg( \frac{25.2}{2}  \bigg)^{2}  -  {(9.7)}^{2}  \\  \\  {x}^{2}  = ( 12.6)^{2}  -  {(9.7)}^{2}  \\  \\  {x}^{2}  = 64.67 \\  \\ x =  \sqrt{64.67}  \\  \\ x = 8.04176598 \\  \\ x \approx \: 8.04

Tell whether the triangle with the given side lengths is a right triangle
Andreas93 [3]

Answer:

not a right triangle

Step-by-step explanation:

The Pythagorean Theorem states that If a triangle is a right triangle,

the hypotenuse^2 will equal to shorter^2 + longer^2

hypotenuse = 18, shorter side = 4, longer side = 17

18^2 = 4^2 + 17^2

324 = 16 + 289

324 = 305

That is false, therefore the triangle is not a right triangle

Can someone help me?
Sladkaya [172]

Answer:

Exponential

374.4

Step-by-step explanation:

This function is not linear. You can tell because the f(x) values do not increase by adding the same number each time.

163.84 + 81.83 = 245.67

245.67 + 122.88 = 368.64

The rate of change is different each time.

The average rate of change from x = 2 and x = 6 is the difference in y values over the difference in x values.

1866.24 - 368.64 = 1497.6

6 - 2 = 4

1497.6 / 4 = 374.4

One afternoon, 27 people withdraw $100 from an ATM. What was the overall change in the amount of money in the machine?​
Usimov [2.4K]

Answer:

The change is a decrease of $2700.

Step-by-step explanation:

Given

Total Number of people = 27

Amount each person withdrew = $100

The total withdrawn amount by 27 people = 100 × 27

                                                                       = $2700

Let M be the amount of money in the ATM at the beginning.

As $2700 was drawn from the ATM, therefore, the change the amount of money in the machine will be:

  • M - 2700

It means the change is a decrease of $2700.
