When you plot te points on a graph you notice it's a parabolaThen its equation is y= x²+bx+c

Plug x & y by their respective values (2 different points are enough) & you will get a system of equation with 2 variables a & b

After solving them you will get a=8/3 & b=-1/4 & c=-5

Hence the equation is y = (8/3)x²-1/4x+5

If the length of the legs of a right triangle are 5 meters and 7 meters, what is the length of the hypotenuse to the nearest ten

TEA [102]

Answer:

8.6 meters

Step-by-step explanation:

a² + b² = c² means leg² + leg² = hypotenuse ²

5² + 7² = hypotenuse²

25 + 49 = hypotenuse²

74 = hypotenuse ²

$\sqrt{74}$ = hypotenuse

8.6 = hypotenuse

What is the length of the side labeled x?

Scorpion4ik [409]

Answer:

AB = 42.15 units

Step-by-step explanation:

In triangle ABD,

By applying Cosine rule in this triangle,

cos(30)°= $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3} }{2}$ = $\frac{AD}{AB}$

$\frac{\sqrt{3}}{2}=\frac{AD}{47}$

AD = $\frac{47\sqrt{3}}{2}$

By applying tangent rule in ΔACD,

tan(44)° = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(44)° = $\frac{AD}{x}$

0.9657 = $\frac{\frac{47\sqrt{3}}{2}}{x}$

0.9657 = $\frac{47\sqrt{3}}{2x}$

x = $\frac{47\sqrt{3}}{2(0.9657)}$

x = 42.15

≈ 42.2 units
