The product of the given numbers is 1.61 × 10⁸.

What is meant by Scientific Notation?

Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.

For example, 30,000 can be written as 3 × 10⁴.

Given that,

We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).

The numbers in scientific notation uses exponents.

So we have to use the product rule of exponents here.

(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)

                              = 16.1 × (10¹ x 10⁶)

We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ

So the product is,

(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)

                              = 16.1 × 10⁷

                              = 1.61 × 10⁸

Hence the product in scientific notation is 1.61 × 10⁸.

f(x) = x2 – 5x – 2, Linear



f(x) = 3.4"

Answers

Answer:

y = 2x + 4

Step-by-step explanation:

The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.

The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).

Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.

Therefore, the right asnwer is the linear function

The function that  could have at most 1 x-intercept is y = 2x + 4.

What is a linear function?

It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.

The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points  that represent concave down.

Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.

Therefore, it should be a linear function.

Answer:

Square root property

Step-by-step explanation:

The given equation is :

[tex]x^2+6=31[/tex]

We need to write the most appropriated technique to solve the above equation.

Subtracting both sides of the above equation by 6 such that,

[tex]x^2+6-6=31-6\\\\x^2=25[/tex]

Now taking square root on both sides we get :

y = 2/3x +4

Step-by-step explanation:

The y intercept is where the line crosses the y axis

y intercept =4

We can find the slope using two points on the line

(0,4) and (3,6)

m = (y2-y1)/(x2-x1)

   = (6-4)/(3-0)

   = 2/3

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2/3x +4

Answer:

y = 2/3x +4

Step-by-step explanation:

let the 2 unknown be a and b

X = 0, Y = 4 -> 4 = 0*a+b -> b = 4

Y =0, X = -6  -> 0 = -6*a + 4 -> a = -4/-6 = 2/3

-> y = 2/3x +4

Which inequality is true for x = 2?

A) 6x + 20 < 29
B) 7x − 10 < 11
C) 14x + 10 < 37
D) 15x − 18 < 12

Answers

Answer: d.

Step-by-step explanation:

Add 18 to both sides.

15x<12+18

Simplify  12+18  to 30.

15x <30

Divide both sides by 15.

x < 15/30

Simplify 30/15 to 2.

x < 2

​​

The inequality 15x − 18 < 12 is true for x = 2

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, are some inequalities, we need to find which of them is true for  x = 2

a) 6x + 20 < 29

Solving for x,

6x + 20 < 29

6x > 9

x > 3

b) 7x − 10 < 11

7x < 21

x < 3

c) 14x + 10 < 37

14x > 27

x > 27/14

d) 15x − 18 < 12

15x < 30

x < 2

Hence, the inequality 15x − 18 < 12 is true for x = 2
