Answer:
b.0.26 is the correct answer
Step-by-step explanation:
a is incorrect because that would be .40 and .40 is more than .27 so that would make the equation false
c is in correct because .3 is.30 and .30 is more than. 27 and this would make the equation false
and d is incorrect because .28 is more than. 27 would make the equation false
Answer:
the area of the game room would be 15 yards by 10 yards
Step-by-step explanation:
you multiply the number of feet by 5
the five being the number of yards that are in a foot
Answer:
- (x + 3)(x - 3)(x² - 2x + 5)
Step-by-step explanation:
<u>One of the zeros given:</u>
<u>Since it is a complex number, its conjugate is also a zero:</u>
<u>The product of two factors are:</u>
- (x - (1 + 2i))(x - (1 - 2i)) =
- x² - x(1 + 2i + 1 - 2i) + (1 - 4i²) =
- x² - 2x + 5
<u>We need two more zeros. Let them be m and n, then we have:</u>
- (x - m)(x - n) = x² - (m +n)x + mn
<u>The product of all factors:</u>
- (x² - 2x + 5)(x² - (m+n)x + mn) = x⁴ - 2x³ - 4x² + 18x - 45
- x⁴- (m+n+2)x³ + (mn+5)x² - (2mn+5m+5n)x + 5mn = x⁴- 2x³- 4x²+ 18x- 45
<u>Compare left and right sides and solve for m and n:</u>
- m + n + 2 = 2 ⇒ m + n = 0
- mn + 5 = -4 ⇒ mn = -9
- 2mn + 5(m + n) = -18 ⇒ mn = -9
<u>From the above equations we get:</u>
- m = -n
- -n² = -9
- n = 3
- m = -3
The other zero's are 3 and -3
<u>All of the factors:</u>
- (x + 3)(x - 3)(x² - 2x + 5)
Alright here I go:
9.98 * 10^6 in standard form is 9,980,000
7.3 * 10^7 in standard form is 73,000,000
73,000,000 subtracted by 9,980,000 is 63020000.
63020000 in scientific notation is 6.302 * 10^7
Hope I helped!
