Can someone please help me with answering this

insens350 [35]

Answer:

? = 1 (assuming right-angled triangle)

Step-by-step explanation:

This is an application of Pythagoras' Theorem, but rearranged:

$a^{2} = c^{2} - b^{2}$

$\sqrt{10}^{2}$ is, of course, 10, so 10 - 9 = 1, and $\sqrt{1} = 1$ .

A full grain silo

Kazeer [188]

Answer:

m is the slope.

b is the y-intercept.

the slope is the same as he constant rate.

let y = the number of feet of grain left in the silo.

let x = the number of seconds.

you get y = -3.5 * x + b.

when x = s seconds, the equation becomes y = -3.5 * s + b.

b is the y-intercept which is the value of y when x = 0.

when x = 0, no seconds have elapsed and the silo is therefore at whatever height it was before you started to empty it.

that would be the value of b.

if we assume that the height of the grain in the silo was 150 feet, then the formula would become

Step-by-step explanation:

y = -3.5 * x + 150

after s seconds, the formula would become y = -3.5 * s + 150.

if s was equal to 20, then the formula would become y = -3.5 * 20 + 150 which would then become y = -70 + 150 which would then become y = 80.

after 20 seconds, there would be 80 feet of grain left in the silo.

the graph of the equation would look like this.

from the graph, you can see that the height of the grain in the silo is 150 feet when you start and gets down to 80 feet after 20 seconds and that the silo will be empty somewhere between 42 and 43 seconds.

What is the y-intercept for the equation y = 11x + 1?

Dafna11 [192]

Answer:

$(0, 1)$

Step-by-step explanation:

<u>Step 1: Determine the y-intercept</u>

Using the slope intercept form, we know that the equation is y = mx + b where m is the slope and b is the y-intercept. Therefore, looking at our equation, we can tell that b is 1 therefore the y-intercept is (0, 1)

Answer: $(0, 1)$
