A shadow 12 meters long is cast by a fir tree that is 16 meters tall. What is the length of the shadow cast by a nearby ash tree

mrs_skeptik [129]

Answer: 5 m

Step-by-step explanation:

Given

Length of 16 m fir tree is 12 m

length of the ash tree is 8 m

Suppose x is the length of the ash tree

angle $c$ made by fir and ash tree will be same as shown in figure

$\Rightarrow \tan c=\dfrac{16}{12}=\dfrac{8}{x}\\\\\Rightarrow x=8\times \dfrac{12}{16}\\\\\Rightarrow x=5\ m$

What is the equation of a line that passes<br> through the point (-1, -7) and has a slope of 5?

yulyashka [42]

Answer:

$y=5x-2$

$5x-y-2=0$

Step-by-step explanation:

Line is passing through the point (-1, -7)

$\implies x_1 = -1,\: y_1=-7$

Slope of line (m) = 5

Equation of line in point-slope form is given as: $y- y_1=m(x-x_1)$

Substituting the values of $\implies x_1,\: y_1\: \&\: m$ in the above equation, we find:

$y- (-7)=5[x-(-1)]$

$\implies y+7=5[x+1]$

$\implies y+7=5x+5$

$\implies y=5x+5-7$

$\implies y=5x-2$

$\implies 5x-y-2=0$
