Graph x ≤ 4, and y≥ -8.

LUCKY_DIMON [66]

Line with a formula of x = a is a vertical line while a line with a formula of y = b is a horizontal line on the other hand. In this case, the graph of x ≤ 4 is the region to the left of the line x = 4 to negative infinity. The graph of y≥ -8 is the region above the line y = -8 to positive infinity.

If p(x)=2x^2-4x and q(x) = x-3, what is (p o q)(x)

lesya692 [45]

Answer:

2x² - 16x + 30

Step-by-step explanation:

To evaluate (p ￮ q)(x)

Substitute x = q(x) into p(x)

2(x - 3)² - 4(x - 3)

= 2(x² - 6x + 9) - 4x + 12

= 2x² - 12x + 18 - 4x + 12

= 2x² - 16x + 30

a surveyor measures the distance to the two landmarks as shown in the diagram what is the distance d. between the landmarks

Inessa [10]

<h3>The distance between two landmarks is 123 meters</h3>

Solution:

We have to find the distance between two landmarks

Use the law of cosines

The third side of a triangle can be found when we know two sides and the angle between them

$c^2 = a^2 + b^2 - 2ab\ cos c$

Here, angle between 90 meters and 130 meters is 65 degrees

From figure,

a = 90

b = 130

c = d

Therefore,

$d^2 = 90^2 + 130^2 - 2(90)(130)\ cos 65\\\\d^2 = 8100 + 16900 - 23400\ cos\ 65\\\\d^2 = 25000 - 23400 \times 0.4226\\\\d^2 = 25000 - 9889.267\\\\d^2 = 15110.73\\\\d = 122.92\\\\d \approx 123$

Thus, the distance between two landmarks is 123 meters
