Chang used a coordinate plane to show where his posters are displayed on his bedroom wall. Three posters are located at E(5, 3),
arlik [135]

Answer:

EF = 9

GF = 2

Step-by-step explanation:

For EF, we want to find the distance between their c coordinates, since their y coordinates are the same. We want the distance between -4 and 5, which when you add their distance from 0, is 9.

For GF, they share the same x coordinate, so you're finding the distance between their y coordinates, which are 3 and 5. The distance between the two is 2, so the length of GF is 2.

The total cost for buying new sneakers for the basketball team an be found by using the function y=25x + 65, is where x is the n
gtnhenbr [62]

Answer:

Domain\ =\ \{x: 9,10,11....16\}

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>

Step-by-step explanation:

Given

y = 25x + 65

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

Domain\ =\ \{x: 9,10,11....16\}

Solving for the range;

<em>When x = 9</em>

<em></em>y = 25 * 9 + 65<em></em>

<em></em>y = 225 + 65<em></em>

<em></em>y = 290<em></em>

<em></em>

<em>When x = 10</em>

<em></em>y = 25 * 10 + 65<em></em>

<em></em>y = 250 + 65<em></em>

<em></em>y = 315<em></em>

<em></em>

<em>When x = 11</em>

<em></em>y = 25 * 11 + 65<em></em>

<em></em>y = 275 + 65<em></em>

<em></em>y = 340<em></em>

<em></em>

<em>You continue till you get to x = 16</em>

<em>---</em>

<em>--</em>

<em>-</em>

<em>When x = 16</em>

<em></em>y = 25 * 16 + 65<em></em>

<em></em>y = 400 + 65<em></em>

<em></em>y = 465<em></em>

<em></em>

<em>Hence; the range is</em>

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>

Find the exact value of cos 75 by using a sum or difference formula
anygoal [31]
Cos 75 = 45 + 30

Formula: cos 45 x cos 30 - sin 45 x sin 30

Cos 45 = root 2 / 2
Cos 30 = root 3 / 2
Sin 45 = root 2 / 2
Sin 30 = 1 / 2
