How many zeros does this 7.185629 x 10^2985 have?
Answer: 2979 Zeroes
Step-by-step explanation:
1. Figure out what 10^2985 is. (It's one followed by 2985 zeroes).
2. Using that knowledge, make 7.185629 a whole number. To do that, you need to multiply it by a number that has the same number of zeroes as it does to move the decimal place one by one to the right. In this case, it is 1,000,000, because it has 6 zeroes and you need to move the decimal point past 6 numbers (after 7 in 7.185629).
3. Subtract 2985 by 6, because you used 6 zeroes.
4. This gives you the answer 2979 zeroes because 2985 zeroes - 6 zeroes= 2979 zeroes.

triangular prism
using the net.
7 cm
5 cm
4 cm
6 cm
5 cm
The surface area of the triangular prism is 136 cm square.
How to find the surface area of a triangular prism?The surface area of a triangular prism can be found as follows;
Therefore,
surface area of a triangular prism = (perimeter of the triangle × height of prism) + (2 × base area)
Hence,
perimeter of the triangle = 5 + 5 + 6
perimeter of the triangle = 16 cm
height of prism = 7 cm
base area = 1 / 2 bh
base area = 1 / 2 × 4 × 6
base area = 24 / 2
base area = 12 cm²
Therefore,
surface area of a triangular prism = (16 × 7) + (2 × 12)
surface area of a triangular prism = 112 + 24
surface area of a triangular prism = 136 cm²

The angle of ∠FEG is 58 degrees
How to find angles?The angle DEF is a right angle.
Therefore,
∠DEF = 90°
Hence,
∠FEG + ∠GED = ∠DEF
∠FEG = 5x - 22
∠GED = 2x
∠DEF = 5x - 22 + 2x
90 = 5x + 2x - 22
90 = 7x - 22
90 + 22 = 7x
112 = 7x
divide both sides by 7
x = 112 / 7
x = 16
∠FEG = 5x - 22
∠FEG = 5(16) - 22
∠FEG = 80 - 22

The nature of the roots in the given quadratic equation (x - 3)² + (x - 4)² = 0 is; A: two rational roots
What are the roots of the Quadratic Equation?We are given the quadratic equation;
(x - 3)² + (x - 4)² = 0
Now, some of the rules in naming the roots are;
If b² – 4ac > 0, then the roots are real and unequal
If b² – 4ac = 0, then the roots are real and equal
If b² – 4ac < 0 then the roots are unequal and Imaginary
If b² – 4ac > 0 (is a perfect square), then the roots are real, rational and unequal
If b² – 4ac > 0 (is not a perfect square), then the roots are real, irrational and unequal
From the above rules and comparing to our given equations, it is clear that we have two rational roots which are x = 3 and x = 4.

Find each product or quotient. 7√7 . 3√7
The given expression can be solved by determining the product of irrational numbers.
Irrational number is a real number that cannot be expressed as the quotient of two integers. If a square root of a number is not a perfect square root, then it is an irrational number.
In the given expression, there are two rational numbers 7 and 3 while two irrational numbers √7 and √7.
The integer 7 and 3 can be multiplied. Hence,
7√7*3√7=7*3*√7*√7=21*√7*√7
When multiplying terms in square root, √a*√b=√ab. Hence,
21*√7*√7=21√7*7
As square root of a number is the number multiplying itself i.e., √a*a=a

Identify slope from a graph
The mathematical definition of slope is very similar to our everyday one. In math, slope is used to describe the steepness and direction of lines. By just looking at the graph of a line, you can learn some things about its slope, especially relative to other lines graphed on the same coordinate plane. Consider the graphs of the three lines shown below:
You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope. Let’s look at an example.
EXAMPLE
Use the graph to find the slope of the line.
A line that crosses the points (2,1) and (6,3). A blue line labeled Rise goes up two units from the point (2,1). A red line labeled Run goes left from the point (6,3) so that it forms a triangle with the main line and the Rise line. A formula says slope equals rise over run.

This line will have a slope of

and the

Let’s look at another example.
EXAMPLE
Use the graph to find the slope of the two lines.
A graph showing two lines with their rise and run. The first line is drawn through the points (-2,1) and (-1,5). The rise goes up from the point (-2,1) to join with the run line that goes right to the point (-1,5). The second line is drawn through the points (-1,-2) and (3,-1). The rise goes up from the point (-1,-2) to join with the run to go right to the point (3,-1).

Solve. Check for extraneous solutions. (7 x+6)¹/₂-(9+4 x)¹/₂=0
No Extraneous solution
The given equation is
( 7x + 6 ) ^ 1/2 - (9 + 4x ) ^ 1/2 = 0
We have to find the value of x
[tex]\sqrt{7x + 6}[/tex] = [tex]\sqrt{9 + 4x}[/tex]
Squaring both sides of the equation
[tex](\sqrt{ 7x + 6} )^{2}[/tex] = [tex](\sqrt{9 + 4x})^{2}[/tex]
7x + 6 = 9 +4x
3x = 3
x = 1
To know whether the value of x is the extraneous solution or not, put the value of x in the equation
[tex]\sqrt{7 * 1 + 6}[/tex] -[tex]\sqrt{ 9 + 4 * 1}[/tex] = 0
[tex]\sqrt{13}[/tex] - [tex]\sqrt{13}[/tex] =0
0 = 0
