I hope this helps you

1 1/2=1.2+1/2=3/2

2 1/3=2.3+1/3=7/3

7/3-3/2

7.2/3.2-3.3/2.3

14/6-9/6

Use the quadratic formula to determine the exact solutions to the equation.

zmey [24]

For this case we have the following equation:
x ^ 2-2x-4 = 0
We use the quadratic formula:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values we have:
x = (- (- 2) +/- root ((- 2) ^ 2 - 4 * (1) * (- 4))) / (2 * (1))
Rewriting we have:
x = (2 +/- root (4 + 16)) / 2
x = (2 +/- root (20)) / 2
x = (2 +/- root (4 * 5)) / 2
x = (2 +/- 2raiz (5)) / 2
x = (1 +/- root (5))
The roots are:
x1 = (1 + root (5))
x2 = (1 - root (5))
Answer:
x1 = (1 + root (5))
x2 = (1 - root (5))

A tree casts a shadow that is 18 feet in length. If the angle of elevation is

FinnZ [79.3K]

It forms a Triangle, in which base is shadow, and height of the tree is perpendicular.

So, Tan Ф = P / B
Tan 28 = P /18
0.53 * 18 = P [ Tan 28 = 0.53 ]
P = 9.6

In short, Your Answer would be Option D

Hope this helps!

A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in fe

wel

Answer:

$\boxed{33.5 \ \text{feet/second}}$

Step-by-step explanation:

To find the <u>unit rate,</u> we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.

<u>Note:</u> Since the cyclist travels at a <u>constant rate</u>, unitary method can be used.

$\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}$

$\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}$

<u>Divide both sides by 25:</u>

$\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}$

$\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}$

$\rightarrow \boxed{33.5 \ \text{feet/second}}$
