Answer:
at N ≥ 6
Step-by-step explanation:
Error permissible = 0.001
The series = infinity
at ( N + 1 ) ! > 1000 the inequality N ≥ 6 is valid and holds
attached below is the detailed solution using alternating series remainder
Answer:
Step-by-step explanation:
Triangle:
Base = 4 units
Height = 3 units {perpendicular height}
= 6 square units
Rectangle:
To find the area count the number of squares. Number of square = 6
Area = 6 square units
or You can find the area of the rectangle as bellow also
Length = 3 units
Width = 2 units
Area = length*width
= 3*2
= 6 square units
Both the triangle and rectangles has the same area 6 square units
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and write them in exponential form.
R=logI
2011 earthquake:
9.1I=logI=109.1
2003 earthquake:
8.3I=logI=108.3
Form a ratio of the intensities.
intensity for 2011intensity for 2003
Substitute in the values and divide by subtracting the exponents to find
109.1108.3100.8≈6.
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Your answer:
The intensity of the 2011 earthquake was about 15 times the intensity of the 2003 earthquake.
Answer:
Kobby is 1 and Nana is 6
Step-by-step explanation:
lets mark Kobby's present age x, than Nana's present age would be x+5.
four years later Kobby's age would be x+4, and Nana's x+5+4, or 2(x+4).
so
x+5+4=2x+8
x-2x=8-5-4
-x=-1
x=1
