Given the vectors u = <5,-1> and v = <1,12>, find -7u-3v. *

zepelin [54]

You multiply vectors and scalar simply by multiplying each component by that scalar:

$-7u = \langle-35,7\rangle,\quad -3v=\langle -3,-36\rangle$

Finally, you sum two vectors by summing the correspondent coordinates:

$-7u-3v = \langle-35,7\rangle+\langle -3,-36\rangle = \langle-38,-29\rangle$

Mrs.Brown biked 35 miles in 2.5 hours. How many miles could she bike in 3 hours at the same rate

quester [9]

35 divided by 2.5 is 14, so she biked 14 miles in 1 hour. So 14*3= 42

She can bike 42 miles in 3 hours.

*BRAINLIEST* (EASY QA: Warm UP) Find a positive solution to each equation: x2 = 1/4

Georgia [21]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's get it solved :}$

$\sf{x² = \dfrac{1}{4}}$

$\sf{x = \sqrt{\dfrac{1}{4}}}$

$\sf{x= \pm{\dfrac{1}{2}}}$

$\sf{x ={\dfrac{1}{2}} }$

$\textsf{[ since we need positive solution ]}$

$\textsf{Correct choice is C}$
