Answer:

$0.46

Step-by-step explanation:

To find the unit rate you have to divide, so our equation is:

5.99 ÷ 13 = 0.46 (rounded)

So the unit rate of 5.99:13 is 0.46:1

Line l contains the points (1,5) and (4, -4). point P has the coordinates (-1, 1)
Colt1911 [192]

Answer:

The distance from p to l is \sqrt{10}\ units

Step-by-step explanation:

we know that

The distance between point p from line l is equal to the perpendicular segment from line l to point p

step 1

<em>Find the slope of line l</em>

we have the points

(1,5) and (4, -4)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-4-5}{4-1}

m=\frac{-9}{3}

m=-3

step 2

Find the equation of the line l

The equation in point slope form is equal to

y-y1=m(x-x1)

we have

m=-3

point\ (1,5)

substitute

y-5=-3(x-1) -----> equation A

step 3

Find the slope of the line perpendicular to the line l

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (The product of their slopes is equal to -1)

m_1*m_2=-1

we have

m_1=-3 ---> slope of line l

therefore

m_2=\frac{1}{3} ----> slope of the line perpendicular to line l

step 4

Find the equation of the line perpendicular to line l that passes through the point p

The equation in point slope form is equal to

y-y1=m(x-x1)

we have

m=\frac{1}{3}

point\ p(-1,1)

substitute

y-1=\frac{1}{3}(x+1) -----> equation B

step 5

Solve the system of equations

y-5=-3(x-1) -----> equation A

y-1=\frac{1}{3}(x+1) -----> equation B

Solve the system by graphing

The solution of the system is the intersection point both graphs

The solution is the point q(2,2)

see the attached figure

step 6

we know that

The distance between the point p and the line l is equal to the distance between the point p and the point q

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have the points

p(-1,1) and q(2,2)

substitute the values

d_p_q=\sqrt{(2-1)^{2}+(2+1)^{2}}

d_p_q=\sqrt{(1)^{2}+(3)^{2}}

d_p_q=\sqrt{10}\ units

Two similar triangles have have areas of 75 m2 and 12 m2. find the ratio of the perimeters
soldi70 [24.7K]

we know that having similar triangles so the ratio of sides,area and volume are same.

s/s=s^2/s^2

we know that s^2 will be the area of triangle.

s^2/s^2=75/12

so s/s=\sqrt{75/12}

so the ratio of the perimeter of two triangles will be

(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )

ratio of the perimeter=\sqrt{225} /\sqrt{36}

Suppose that $9500 is placed in an account that pays 8% interest compounded each year.
Blababa [14]

\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$9500\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{each year, thus once} \end{array}\dotfill &1\\ t=years\dotfill &1 \end{cases}


\bf A=9500\left(1+\frac{0.08}{1}\right)^{1\cdot 1}\implies A=9500(1.08)\implies \boxed{A=10260} \\\\\\ \stackrel{\textit{after 2 years, t = 2}}{A=9500\left(1+\frac{0.08}{1}\right)^{1\cdot 2}}\implies A=9500(1.08)^2\implies \boxed{A=11080.8}
