Answer:

B) 2

Step-by-step explanation:

add the 2 and 6

them multiply 8 and 2

so then you would have, 48 divided by 16-1

then divide the 48 and 16

then subtract 3-1

a positive real number is 8 less than another. if the sum of the squares of the two numbers is 80 find the numbers

Ray Of Light [21]

Answer:

$a = -4 + 2\sqrt{6}, b = 4 + 2\sqrt{6}$

Step-by-step explanation:

Let a,b - the 2 numbers.

$a+8 = b\\a^2 + b^2 = 80\\a^2 + (a+8)^2 = 80\\2a^2 + 16a + 64 = 80\\2a^2 + 16a - 16 = 0\\a^2 + 8a - 8 = 0\\a_{12} = \frac{-8 \pm \sqrt{64 - 4(-8)}}{2} = \frac{-8 \pm 4\sqrt{6}}{2} = -4 \pm 2\sqrt{6}\\b_{12} = 4 \pm 2\sqrt{6}\\ 4 < 2\sqrt{6} => a = -4 + 2\sqrt{6}, b = 4 + 2\sqrt{6}$

Nadusha1986 [10]

Answer:

637.5

Step-by-step explanation:

$a_{1}=2.5=a\\a_{5}=40=ar^4\\r=2 \ \& \ a=2.5\\\text{Sum}=\frac{a(r^n-1)}{r-1}=\frac{2.5*(2^8-1)}{1}=637.5$

Mary and Benjamin are driving to their friend Paar's house for a berday party Mary drives 9

SpyIntel [72]

Answer:

3.2 miles

Step-by-step explanation:

Given that Mary drives 9 miles north and 6 miles east to get there, the resultant miles will be achieved by using pythagorean theorem

R = sqrt ( 9^2 + 6^2 )

R = sqrt ( 81 + 36 )

R = sqrt ( 117 )

R = 10.82 miles

while Ben drives 3 miles south and 7 miles west

Use the same pythagorean theorem to find the resultant displacement

R = sqrt ( 3^2 + 7^2 )

R = sqrt ( 9 + 49 )

R = sqrt ( 58 )

R = 7.62 miles

The difference in miles to where Mary and Benjamin live will be difference in the resultant displacement of the two

Difference = 10.82 - 7.62 = 3.2 miles.

Therefore, Mary live 3.2 miles from Benjamin.
