Answer:
12 < x < 16
What we know:
- The longest side of the triangle is 20, another side length is 'x + 4'
- Since the triangle is acute, we know that the value of 'x' will have to be <u>greater than its right triangle value</u> because whatever 'x' equals will result in a <em>right </em>triangle, not an acute one
- We must solve for the <em>right </em>triangle first in order to determine the acute triangle
Solving for 'x' in the right triangle:
- a^2 + b^2 = c^2
- (x+4)^2 + x^2 = 20^2
- x^2 + x^2 + 8x + 16 = 400
- 2x^2 + 8x - 384 = 0
- simplify x^2 + 4x - 192 = 0
- factor (x + 16) (x - 12) = 0
- solve for each 'x' x + 16 = 0 & x - 12 = 0
- x = -16 & x = 12
- check the value of 'x' cannot be negative, so it is not -16. this means the value of 'x' is 12
- the value of 12 for 'x' makes a <em>right triangle, </em>so that is not the answer. this means the the value of 'x' needs to be <em>greater</em> than 12
<u>Checking your answer:</u>
- original equation (x + 4)^2 + x^2 = 20^2
- with answer (12 + 4)^2 + (12)^2 = 20^2
- (16)^2 + (12)^2 = 20^2
- 256 + 144 = 400
- 400 = 400 this is true, so the answer of 'x = 12' is <em>correct </em>for making it into a <em>right triangle</em>
<em></em>
Solving for 'x' in the acute triangle:
- x = 12 makes a right triangle
- x > 12 minimum for an acute triangle
- what is the maximum value for 'x' in the acute triangle? take the two other side lengths --> (x + 4) < 20 (longest side, so it will be the greater number)
- simplify x < 16
- x < 16 maximum for an acute triangle
Conclusion:
- if 'x = 12' makes a right triangle, then 'x > 12' and 'x < 16' are the values that will make it acute
- answer 12 < x < 16
Answer:
y = 6
x = 3
Step-by-step explanation:
To find y and x on a graph, you must count how many squares one dot intercepts the same line as the other dot (in this case it's three) and for the y axis you do the ssme thing; find out how many squares are between both dots between the point where they intercept each other but for this time, it's vertically (in this case it's 6)
Answer:
<h2>Carmello Anthony make more money per game</h2>
Step-by-step explanation:
we are expected to calculate how much each player is making per game, compare the values and tell who makes more money per game
Clayton Kershaw
given data
$30.15 million per year
There are 162 games in a major league baseball season.
therefore a game will be worth
=30,150,000/162
=$186,111
Carmello Anthony
given data
$24.81 million per year
There are 82 games in a NBA season.
therefore a game will be worth
=24,810,000/82
=$302,561
from the analysis, Carmello Anthony make more money per game
The answer is A! If 1/3 is gone, there’s 2/3 left. To find how much 2/3 is, you would multiply 80 by 2/3
