Answer:

you’ve tried and have not won, Never stop for crying; All that’s good and great is done Just by patient trying. Though young birds, in flying, fall, Still their wings grow stronger, And the next time they can keep Up a little longer. Though the sturdy oak has known Many a wind that bowed her, She has risen again and grown Loftier and prouder. If by easy work you’re beat, Who the more will prize you? Gaining victory from defeat, That’s the test that tries you

Can someone graph this? I'll give brainliest.

vodomira [7]

It's nice of you to offer, but no thanks.

To correctly graph this, you need to set up a simple equation and table of values. Luckily, this equation is dead-simple; I'll define y as the total cost and x as the number of water bottles sold.

$y=1.5x$

Since 1.50$ is the cost for one bottle, multiplying that with your variable that defined the amount of bottles, x, gets you the total, y. Now that we have a basic equation, we can begin plugging in values.

Recall that a function is basically just something that takes in a value and returns another one; in our case, it takes the amount of bottles and returns the total cost. Now, plug in the x-values present on the graph (specifically only whole numbers, since you can't have a half bottle). I can't make a proper table but I'll make do.

x y

--------

0 0

1 1.5

2 3

3 4.5

4 6

5 7.5

-----------

Great, now that you have a table of values all you have to do is plug them into the graph, which I've attached. It's pretty crude since I drew it in mspaint but I'm sure you get the point at this point.

Classify the triangle with 9, 15, 19 as an acute right obtuse or not a triangle

Novosadov [1.4K]

Answer:

Hence the correct option is the last one . The triangle is an obtuse angled triangle.

Step-by-step explanation:

i) the sum of any two sides added together is greater than the third side hence this is a triangle.

ii) it is not a right angled triangle as $\sqrt{9^{2} + 15^{2} } \neq 19$ and $\sqrt{9^{2} + 15^{2} } < 19$

iii) the triangle is not acute from ii) above

iv) the triangle is an obtuse triangle from ii) above.

Write an equation in slope intercept form thag passes through (4,-4) and is parallel to 3+4x=2y-9

uysha [10]

The original line is

4x - 2y = -12

The parallel lines will all be

4x - 2y = constant

and the constant is given by the point directly:

4x - 2y = 4(4) - 2(-4) = 24

2y = 4x - 24

y = 2x - 12

Answer: y = 2x - 12

The distance from the center of a carousel to the

anzhelika [568]

Answer:

$\fbox{\begin{minipage}{3.5em}338 (ft)\end{minipage}}$

Step-by-step explanation:

The problem could be simplified as following:

Given:

The radius of a circle O is 26 feet.

Solve for:

The length of arc on circle O that measures 13 radians

Solution:

Step 1: Let's find out the correct formula to apply:

The formula to calculate the length of an arc measuring x radians on a circle with radius r feet is:

L = r*x

Step 2: Let's put the data into formula to work out the length L of arc:

L = 26*13 = 338 (ft)

=> The distance that a horse does on the outer edge travel when the carousel rotates through 13 radians: L = 338 (ft)

Hope this helps!
