Y = x² - 4x + 4
y = 2x - 4

Find intersection of L and C:
x² - 4x + 4 = 2x - 4
x² - 6x + 8 = 0
<span> (x - 2)(x - 4) = 0
x = 2 or x = 4

When x = 2 , y = 2(2) - 4 = 0
When x = 4, y = 2(4) - 4 = 4

Points of intersection = A(2, 0) and B(4, 4)

Find the length of AB:

</span> $
\text {Length of AB}= \sqrt{(4-0)^2 + (4-2)^2} = \sqrt{16 + 4} = \sqrt{20} = 4.47 \text{ units}$
<span>
Answer: 4.47 units

Mark is flying a kite and realizes that 300 feet of string is out. Mark anchored the kite to the ground. The angle of the string

Nadya [2.5K]

Answer:

The kite is 202.7 feet above the ground

Step-by-step explanation:

The scenario is depictedd in the picture attached

we have to find the height.

Trigonometric ratios will be used to find the height.

So,

$sin\ (42.5) = \frac{h}{300}\\ 0.6756=\frac{h}{300}\\0.6756*300=h\\202.68 = h$

The height is 202.68 feet

Rounding off to the nearest tenth

202.7 feet

Therefore, the kite is 202.7 feet above the ground ..

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for t

Tatiana [17]

Answer:

Step-by-step explanation:

1. This is a arithmetic sequence, so the equation is $a_{n}=a_{1}+(n-1)d$ .

$a_{1}$ is -33 and the d is -33.

So, the equation is $a_{n} = -33+(n-1)(-33)$ .

20 POINTS!!!!! What is the value of p in the equation below? 4/5p + 6= -1/3p - 3 <br> p=?

Misha Larkins [42]

For this case we must solve the following equation:

$\frac {4} {5} p + 6 = - \frac {1} {3} p-3$

Adding $\frac {1} {3} p$ to both sides of the equation we have:

$\frac {4} {5} p + \frac {1} {3} p + 6 = -3\\\frac {3 * 4 + 5 * 1} {3 * 5} p + 6 = -3\\\frac {12 + 5} {15} p + 6 = -3\\\frac {17} {15} p + 6 = -3$

Subtracting 6 from both sides of the equation:

$\frac {17} {15} p = -3-6$

Equal signs are added and the same sign is placed:

$\frac {17} {15} p = -9$

We multiply by 15 on both sides of the equation:

$17p = -9 * 15\\17p = -135$

We divide between 17 on both sides of the equation:

$p = - \frac {135} {17}$

Thus, the value of the variable p is $- \frac {135} {17}$

Answer:

$p = - \frac {135} {17}$
