The axis of symmetry for a quadratic equation can be found using the formula x =-b/2a , where a and b are coefficients in the qu
Liula [17]
If x = -b/2a, then 2a = -b / x so a = -b / 2x or a = b / -2x

Answer:

  49.3 feet

Step-by-step explanation:

Shadow lengths and object heights are considered to be proportional, so we have ...

  tree height/(tree shadow) = Andrew's height/(Andrew's shadow)

  height / (85 ft) = (5.8 ft)/(10 ft)

  height = (85 ft)(5.8/10) = 49.3 ft

The tree is 49.3 feet tall.

Which is smaller: an angle showing a turn through 1/8 of a circle or an angle showing a turn through 1/3 of a circle? Explain yo
Zolol [24]

Answer:

An angle showing a turn through 1/8 of a circle is smaller

Step-by-step explanation:

we know that

A complete circle represent 360°

so

<em>An angle showing a turn through 1/8 of a circle is</em>

(360\°)*(\frac{1}{8})=45\°

<em>An angle showing a turn through 1/3 of a circle is</em>

(360\°)*(\frac{1}{3})=120\°

therefore

An angle showing a turn through 1/8 of a circle is smaller
