Answer 1

Answer: 7.012 x 10−8 ==> Option 3

Step-by-step explanation:

(3.012 x 10−8) + (4 x 10−8)=

(3.012+4) x 10−8=

(3.012+4.000) x 10−8=7.012 x 10−8 ==> Option 3

Answer 2

Calculating the expression (3.012 x 10−8) + (4 x 10−8) is 7.012 x 10^(-8).

How to calculate (3.012 x 10−8) + (4 x 10−8).

To calculate (3.012 x 10^(-8)) + (4 x 10^(-8)), we can add the numbers as follows:

(3.012 x 10^(-8)) + (4 x 10^(-8)) = (3.012 + 4) x 10^(-8) = 7.012 x 10^(-8)

So, the correct answer is 7.012 x 10^(-8).

Explain why the image of a figure after a translation is congruent to its preimage.
please does it stays the same size and shape and the only the size is different. please

Answers

Answer: The size and shape will only change when the transformation being made to the figure is a dilation. Since it is only being translated, its image and preimage are still congruent in size.

Step-by-step explanation:

For dilation, the size and shape of a figure only changes when transformed while if translated, the image and preimage of the figure remains congruent in size.

Transformation techniques

Transformation is a way of changing the size and shape of an object in an xy-plane

Some of the transformation techniques used are translations and dilation

Express into partial fractions 3x³ - 5x² - 3x - 40/( x² + 4)(x - 3)

Answers

First simplify the rational expression by dividing. The degree in the numerator has to be at least 1 less than the degree in the denominator before you can decompose into partial fractions.

(3x³ - 5x² - 3x - 40) / ((x² + 4) (x - 3)) = 3 + (4x² - 15x - 4) / ((x² + 4) (x - 3))

Now decompose the remainder term into partial fractions:

(4x² - 15x - 4) / ((x² + 4) (x - 3)) = (ax + b) / (x² + 4) + c / (x - 3)

Multiply both sides by the denominator on the left:

4x² - 15x - 4 = (ax + b) (x - 3) + c (x² + 4)

Expand the right side:

4x² - 15x - 4 = ax² + (b - 3a) x - 3b + cx² + 4c

4x² - 15x - 4 = (a + c) x² + (b - 3a) x - 3b + 4c

Then

a + c = 4

b - 3a = -15

-3b + 4c = -4

Solve this system to get

a = 5, b = 0, c = -1

We end up with

(4x² - 15x - 4) / ((x² + 4) (x - 3)) = 5x / (x² + 4) - 1 / (x - 3)

and so

(3x³ - 5x² - 3x - 40) / ((x² + 4) (x - 3))

= 3 + 5x / (x² + 4) - 1 / (x - 3)

Rearrange w=3(2a+b)-4 to make a the subject

Answers

Answer:

a=[tex]\frac{-1}{2}[/tex]b+[tex]\frac{2}{3}[/tex]+[tex]\frac{1}{6}[/tex]w

Step-by-step explanation:

Original equation: w=3(2a+b)-4

1. Distribute the 3 to the numbers inside parenthesis to get:

w=6a+3b-4

2. Subtract 6a from both sides to get:

-6a+w=3b-4

3. Subtract w from both sides to get:

-6a=3b-4-w

4. Divide both sides by -6 and simplify to get:

a=[tex]\frac{-1}{2}[/tex]b+[tex]\frac{2}{3}[/tex]+[tex]\frac{1}{6}[/tex]w

the measure of an angle in standard position is given. find two positive angles and two negative angles that are coterminal with the given angle.

Answers

To find coterminal angles, you have to either add or subtract 2π. In this case, you would use 8π/4 so there is a common denominator.

Positives:

-3π/4+8π/4 = 5π/4

5π/4+8π/4 = 13π/4

Negative:

-3π/4-8π/4 = -11π/4

-11π/4-8π/4 = -19π/4

What is the measure of an angle?

In geometry, an angle measure is the length of the angle formed by two rays or arms intersecting at a common vertex.

Using a protractor, angles are measured in degrees (°). Joseph Huddart created the protractor in 1801. It was a more sophisticated protractor.

The angle created at the center of a circle is measured in radians, the unit of angular measurement. It is described as an angle that subtends from a circle's center and intercepts at an arc with a radius equal to the circle's radius. 57.3° is equal to one radian.

Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation are the names of basic angles.
