Answer:

They behave similarly in chemical reactions

Step-by-step explanation:

Because their atomic numbers are different, the elements each have a different number of protons and electrons. They belong to the same group, not the same period.

What property can we use to isolate the variable ,f
Stolb23 [73]

Answer:

To isolate variables you can either:

- subtract from both sides

- add to both sides

- multiply both sides (by the same number )

- divide from both sides

These were basic.

Some more advanced ones are :

- raise both sides to the same exponent

- root both sides by the same root.

It has to be an inverse operation however, for all of these properties. And remember, they only work because they are done to both sides.

Find a formula for the exponential function passing through the points (-1,5/3) and (3, 135).
Artyom0805 [142]

The expression y = 4.998 · e^{1.098\cdot x} is the exponential function that passes through the points (- 1, 5 / 3) and (3, 135).

<h3>How to derive an exponential function that passes through two given points</h3>

Herein we find the location of two points set on Cartesian plane that belongs to an exponential function of the form:

y = A \cdot e^{B \cdot x}

Where:

  • A - y-Intercept of the exponential function.
  • B - Growth factor
  • x - Independent variable.
  • y - Dependent variable.

Which is equivalent to the following logarithmic expression:

㏑ y = ㏑ A + B · x

If we know that (x₁, y₁) = (- 1, 5 / 3) and (x₂, y₂) = (3, 135), then the following system of equations is generated:

㏑ (5 / 3) = ㏑ A - B

㏑ 135 = ln A + 3 · B

Then, we solve the system by numerical methods:

㏑ A = 1.609 (A = 4.998), B = 1.098

And the exponential function is equal to y = 4.998 · e^{1.098\cdot x}.

Can you solve this?
marusya05 [52]

Answer:

D

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = 0.5h(a + b)

where h is the perpendicular height and a, b the parallel sides.

Given A = 120, then

0.5 × 8(a + b) = 120, that is

4(a + b) = 120 ( divide both sides by 4 )

a + b = 30 cm → D

Answer:

-20

Step-by-step explanation:

y = 4x + b

-4 = 4(7) + b

-32 = b

y = 4x -32

r = 4(3) - 32

r = -20
