hello :<span>
<span>the parabola's equation is : f(x) = a(x-5)²-5
the coefficient of the squared expression in the parabola's equation is : a
but ; f(6) = - 1
- 1 = a(6-5)²+5
a+5=-1.....a=-6
f(x) = -6(x-5)²+5</span></span>

<span><span>so : a = - 6</span></span>

What are the values of the three trigonometric ratios for angle L, in simplest form?
Stella [2.4K]

Answer:  Sin L =\frac{4}{5} and CosL=\frac{3}{5} and Tan L=\frac{4}{3}

Step-by-Step Explanation:

Since we have given that

Consider, ΔLMN,

LM = 15

MN = 20

NL= 25

\sin L=\frac{Perpendicular}{Hypotenuse}\\\\\sin L=\frac{20}{25}=\frac{4}{5}

And,

\cos L=\frac{Base}{Hypotenuse}\\\\\cos L=\frac{15}{25}=\frac{3}{5}

And,

\tan L=\frac{Perpendicular}{base}\\\\\tan L=\frac{20}{15}=\frac{4}{3}

Hence,

Sin L =\frac{4}{5} and CosL=\frac{3}{5} and Tan L=\frac{4}{3}

oee [108]

Answer:

vvvv

Step-by-step explanation:

1. Make it so 1/4 is an eighth so you can subtract it from 5/8.

1/4 x 2 = 2/8

2. Subtract 2/8 from 5/8.

5/8 - 2/8 = 3/8

Daniel ate 2/8s of the left over pie, and there is 3/8s remaining.
