I need help with questions 1,2, and 3. Would gratefully appreciate it (:

Answer:

Step-by-step explanation:

(2):

First let's organise the data:

33 miles ... x mph ... 4h - downstream

33 miles ... y mph ... 7h - up the stream

x = 33/4 = 8.25 mph

y = 33/7 = 4.71 mph

(3)

P(x) = $x^2 - 2x - 3$

To find the amount of key rings sold when the profit is 5000$ we have to equate P(x) with 5, because in the problem the profit of the key rings is displayed in terms of thousands.

$x^2 - 2x - 3 = 5\\x^2 - 2x - 8 = 0\\x_1 = 4, x_2 = -2$

Since the number of keyrings sold has to be positive the only answer is 4 thousand key rings.

Next, Chad created the graph below showing possible ratios for Pitcher cards to Infield cards in his deck.

<h3>What is the coordinate plane?</h3>

A coordinate plane is a graphing and description system for points and lines. A vertical (y) axis and a horizontal (x) axis make up the coordinate plane. There are four quadrants in the coordinate plane. The point where these lines connect is called the origin (0, 0).

Therefore the first statement is true,

On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.

Therefore option A is correct.

Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?

Bond [772]

Answer:

The second one. (The triangle is not acute because 2+4>5)

Step-by-step explanation:

If you try to make the triangle, one angle would be obtuse so it's not acute.

Pls give brainly, im trying to get the most possible :>
