What is the product of 7.1 * 10^3 and 5.8 * 10^2 expressed in scientific notation?
Answer:
4.118 * 10^6
Step-by-step explanation:
When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.
41.18*10^5 = 4,118*10^6
(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)
Answer:
411.8 · [tex]10^{4}[/tex]
Step-by-step explanation:
7.1 · 10³ × 5.8 · 10²
7.1 × 5.8 = 41.18
10³ + 10² = [tex]10^{5}[/tex]
41.18 · [tex]10^{5}[/tex]
Scientific notation can only have one digit after the decimal.
411.8 · [tex]10^{4}[/tex]
Can someone help me plz I need both the area and perimeter thank you
Answer:
Step-by-step explanation:
do this in parts, take the rectangle in the middle and then the two ends as a whole circle. :)
the rectangle: perimeter : 2*10 ft + 2* 6ft= 32ft
the area: 10*6 = 60 [tex]ft^{2}[/tex]
The circle: perimeter: circumference of circle = 2[tex]\pi[/tex]r or diameter[tex]\pi[/tex] (same thing)
6[tex]\pi[/tex] =18.84955592 ft
area: area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
[tex]\pi[/tex][tex]3^{2}[/tex] = 28.27433388 [tex]ft^{2}[/tex]
add the two part for the totals
total perimeter is: 32 +18.84955592 = 50.84955592 ft
total area is: 60 + 28.27433388 = 88.27433388 [tex]ft^{2}[/tex]

Solve the quadratic equation by completing the square. 0 = x2 – 6x + 4 –4 = x2 – 6x –4 + 9 = (x2 – 6x + 9) 5 = (x – 3)2
Answer:
x = 3±√5
Step-by-step explanation:
Given the quadratic equation;
0 = x² – 6x + 4
Swap sides
x² – 6x + 4= 0
Subtract 4 from both sides
x² – 6x + 4 - 4= 0 - 4
x² – 6x = -4
Complete the square;
Add the square of half of coefficient of x to both sides
Coefficient of x = -6
Half of Coefficient of x = -6/2 = -3
square of the half of Coefficient of x = (-3)²
Add (-3)² to both sides
x² – 6x + (-3)² = -4 + (-3)²
(x-3)² = -4 + 9
(x-3)² = 5
Take the square root of both sides
x - 3 = ±√5
x = 3±√5
This gives the solution to the equation

Classify the triangle with side lengths of 12, 16, 20
Answer:
The triangle is a right triangle
Step-by-step explanation:
We use the pythagorean Theorem which is a^2+b^2=c^2
Now we have 12^2+16^2=20^2
Solve: 144+256=400
400=400

Which sentence is true about equilateral triangle .
A.only 2 sides are the same length
B.only 2 angels have the same measure
C. Each side is a different length
D. All sides are the same length
E. Each angel has a different measure
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Equilateral triangles.

Find the distance between the pair of points.
(2, -2), (-5, -2
Answer:
7
Step-by-step explanation:
Answer:
7 units
Step-by-step explanation:
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Plug in what you know.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(49) + (0) }[/tex]
Add.
[tex]d = \sqrt{(49)[/tex]
Evaluate the radical.
d = ±7
Since distance cannot be negative, our answer is 7.
The distance between the two points is 7 units.

One number is 8 more than another, and their sum is 80. What is the smaller number?
34
36
38
40
========================================================
Work Shown:
x = smaller number
x+8 = larger number, since it's 8 more than the smaller value
Add up those two expressions, and set the sum equal to 80.
Then solve for x.
x+(x+8) = 80
2x+8 = 80
2x = 80-8 ... subtract 8 from both sides
2x = 72
x = 72/2 .... divide both sides by 2
x = 36
The smaller value is 36 while the larger value is x+8 = 36+8 = 44
Note how 36+44 = 80 to help verify the answer.
Answer:
34.
Step-by-step explanation:
80 = (34 + 8) + x
80 = 42 + x
38 = x

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft
