Find the distance between points P(7,7) and Q(1,2) to the nearest tenth

ad-work [718]

Answer:

7.8 units

Step-by-step explanation:

P(Xp, Yp)= (7,7)

Q(Xq, Yq)= (1,2)

distance= l= $\sqrt{(Xp-Xq)^{2} +(Yp-Yq)^{2}}$

l= $\sqrt{(7-1)^{2} +(7-2)^{2}}$

l= $\sqrt{6^{2} } +5^{2}$

l= $\sqrt{61}$

l=7.8102 (to 4 dec. places)

I= 7.8 (to nearest tenth)

PLEASE HELP ASAP!<br> Will mark brainliest :)

Answer:

x = abc/ (a+b)

Step-by-step explanation:

x/a + x/b = c

Multiply by ab to get rid of the fractions

ab(x/a + x/b) = abc

bx + ax = abc

Factor out an x

x( b+a) = abc

Divide each side by (a+b)

x ( a+b)/ (a+b) = abc/ (a+b)

x = abc/ (a+b)

Answer:

$solve \: when \: (f + g) \:(4) \\ \\ first \: solve \: for \: f(x) \\ \: \\ solution \: .... \\ \\ f(x) = 4x - 3 \\ f(4) = 4(4) - 3 \\ f(4) = 16 - 3 \\ f(4) = 13 \\ \\ \\ now \: solve \: for \: g(x) \\ \: \\ solution \: .... \\ \\ g(x) = {x}^{3} + 2x \\ g(x) = {(4)}^{3} + 2(4) \\ g(x) = 64 + 8 \\ g(x) = 72 \\ \\ (f) - (g) = 13 - 72 \\ (f) -(g) = -59$
