What are the roots of x in the equation −4−14x=x+5 ?

1 answer:

4 0

First you would subtract x from both sides to move all the x's to one side Then you would add 4 to both side to move all the non x's to one side Lastly divide by negative 15 to have x by itself 9/-15 =-.6 So x as has root at x=-0.6

What is the approximate distance between the points (-3, -4) and (-8, 1) on a coordinate grid

tatyana61 [14]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}

\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -3 &,& -4~) 
% (c,d)
&&(~ -8 &,& 1~)
\end{array}\\\\\\ % distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{[-8-(-3)]^2+[1-(-4)]^2}\implies d=\sqrt{(-8+3)^2+(1+4)^2}
\\\\\\
d=\sqrt{25+25}\implies d=\sqrt{2\cdot 25}\implies d=\sqrt{2\cdot 5^2}\implies d=5\sqrt{2}$

A plane flying a straight course observes a mountain at a bearing of 30.3degrees to the right of its course. At that time the pl

Svetllana [295]

Answer:

12km or 12 kilometers

Step-by-step explanation:

We are given the following values:

For the first bearing we have:

30.3 degrees at a distance of 9 kilometers

We are asked to find the second distance of the second bearing at 40.3 degrees

Therefore, we have:

30.3 degrees = 9km

40.3 degrees = ?? Unknown( we designate this as y)

We crossmultiply

30.3 degrees × y = 9km × 40.3 degrees

Divide the both sides by 30.3 degrees

y = (9km × 40.3 degrees) ÷ 30.3 degrees

y = 362.7/30.3 degrees

y = 11.97029703 km

Approximately to the nearest tenth of a km

y = 12km.

Therefore, the distance of the plane from the mountain when the second bearing is taken (to the nearest tenth of a km) is 12km.

You bought a baseball card for $5. It appreciates 5% every year. How much will the card be worth after 38 years?

goldenfox [79]

Answer:

$ 31.925

Step-by-step explanation:

Final Value = a (1+r)^n

a = initial amount, r = appreciation rate, n = no. of time periods

a = 5 , r = 5% = 0.05 , n = 38

5 (1+0.05)^38

5 (1.05)^38

5 (6.385)

= 31.925
