The scientific notation and standard form values of A-B-C are as follows:

A) 7.4 is 100 million times larger than 7.4 x 10⁻⁸

B) 10⁻⁸ is 100 million times smaller than 10.

C) The value 7.4 x 10⁻⁸ is 527 times smaller than 0.000039.

We use scientific notation in writing large or small numbers by multiplying a number between 1 and 10 by a power of 10.

3.9 x 10⁻⁵         0.000039

7.4 x 10⁻⁸          0.000000074

7.4 is 100 million times larger than 7.4 x 10⁻⁸ because 7.4 x 10⁻⁸ = 0.000000074, showing that the decimal point is moved 8 places to the right to get 7.4.  8 zeros are 100 million.

Thus, scientific notations reduce the large numbers so that they are multiplied by the power 10, which may be positive or negative.

Answer: -1

Step-by-step explanation:

    We will find the answer to this question by isolating the x variable.

    Given:

2(3x – 1) ≥ 4x – 6

    Distribute the 2 with multiplication:

6x – 2 ≥ 4x – 6

    Add 2 to both sides of the equation, and subtract 4x from both sides of the equation:

2x ≥ – 4

    Divide both sides of the equation by 2:

x ≥ -2

    The only value given that is greater than or equal to -2 is -1, leaving us with an answer of;

The correct answer is D. the x- intercept of the given graph is (-1.75,0) and y - intercept is (0,3)

The x-intercept is the location where a line's graph crosses the x-axis.

The y-intercept is the location where a line's graph crosses the y-axis.

The shapes of these points are (x,0) and (0,y), respectively.

Utilize the fact that all x-intercepts have a y-value of zero and all y-intercepts have an x-value of zero to get the x- and y-intercepts algebraically. Set x=0 and find the equivalent y value to calculate the y -intercept. Set y=0 and then figure out the matching x value to discover the x -intercept.

Step-by-step explanation:

Answer:

Mei is correct because -9 is to the left of -3 on the number line.

Step-by-step explanation:

This is because -9 is LESS than -3, when you add or subtract using negative numbers, such as 7-9, you get -2. However when you subtract 7-13, you get -6. Because you subtracted a greater number from 7, your answer is -6 is LESS than -2. This is the same with inequalities, greater negative numbers will always be smaller and smaller negative numbers will always be greater.

Answer:

The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

Step-by-step explanation:

It is given that a line perpendicular to YX passes through the point (3,-8).​

Now,

The slope of the line perpendicular to the line YX is 1.

=> y = x

So, Slope = 1

Furthermore, the slope of the required line can be written as -1.

So, the required line can be written in slope-intercept form as;

=>  y = − x + c

It is further given that the line passes through the point (3,2);

So, after putting all the value in the above-mentioned equation, we get;

=> 2 = − 3 + c

=> c = 5

So, x + y = 5

Therefore, the line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.

It is given that a line perpendicular to YX passes through the point (3,-8).​

Now,

The slope of the line perpendicular to the line YX is 1.

=> y = x

So, Slope = 1

Further more, the slope of the required line can be written as -1.

So, the required line can be written in slope-intercept form as;

=>  y = − x + c

It is further given that the line passes through the point (3,2);

So, after putting all the value in the above-mentioned equation, we get;

=> 2 = − 3 + c

the formula for the polynomial is:

p(x) = (-3/10)*(x - 2)^2*(x + 5)

Here we have a polynomial with the following roots:

So, if we define A as the leading coefficient, we can write the polynomial as:

p(x) = A*(x - 2)^2*(x + 5)

We know that the y-intercept is -6, so evaluating in x = 0 we should get:

p(0) = -6 = A*(0 - 2)^2*(0 + 5) = A*4*5 = A*20

The number of toppings where the cost of each pizza would be equal is 5.

The first step is to formulate an equation that represents the cost of each type of pizza.

Total cost = price of cheese pizza + (price per topping x number of toppings)

Cost of pizza A = $10 + $1.50t

Cost of pizza B = $12.50 + t

When the cost of both pizzas are equal, the above equations would be equal to each other.

$10 + $1.50t = $12.50 + t

To determine the value of t, take the following steps:

Combine similar terms: 1.50t - t = $12.50 - $10

Add similar terms = 0.50t = 2,50

Divide both sides by 0.50 = t = 2.50 / 0.50

Answer:

[tex]\sqrt{20} \text{ or } 2\sqrt{5}[/tex]

Step-by-step explanation:

So in this question we want to use the Pythagorean Theorem which essentially gives us a relationship between the sides of a triangle and is as follows: [tex]a^2+b^2=c^2[/tex]

In this formula the "a" and "b" represent the base and the height and "c" represents the hypotenuse of the triangle

The order in which you assign "a" and "b" do not matter, so let's just say that: [tex]a=4\ \text{and}\ c=6[/tex]

Although it is important that you assign the hypotenuse to "c".

So plugging in known values we have the equation:

[tex]4^2 +b^2=6^2[/tex]

Square the values

[tex]16+b^2=36[/tex]

Subtract1 16 from both sides

[tex]b^2=20[/tex]

take the square root of both sides

[tex]b=\sqrt{20}[/tex]

This "b" represents our other side, which we did not initially know, so this is our answer :)

You can simplify this further by separating the radical into: [tex]\sqrt{20} = \sqrt{4} * \sqrt{5} = 2\sqrt{5}[/tex]

The true statement about the continuity of f(x) at x=−3 is (c) lim x -> -3 f(x) ≠ f(-3)

The graph represents the given parameter

On the graph, there is an open circle at x = -3

This means that there is a removable discontinuity at x = -3

A removable discontinuity at x = -3 implies that

lim x -> a at f(x) exists

However,

lim x -> a at f(x) does not equal lim x -> a at f(a)
