Correct I’ll give brainlist no links or I’ll report
Elenna [48]

Since he started with Nothing

He had zero initially

After x Months...

He'll have 10x naxvips

in slope intercept form

y=10x

To get the y values ... substitute the corresponding x value

For x=0

y=10(0)

y=0. Which is true cos he had no naxvip initially

x=1

y=10(1)

=10. Which is true cos he buys 10 more monthly... So 10 + 0 = 10.

x=2

y=10(2) = 20. This is true cos he added an additional 10 after each month

x=7

y=70.

Suppose you are climbing a hill whose shape is given by the equation z = 1400 − 0.005x2 − 0.01y2, where x, y, and z are measured
Anarel [89]
Answer: You start to ascend

Explanation:

Since you are walking due south and the positive y-axis points north, the y-coordinate decreases.

Let 

y' = y-coordinate after walking due south
z' = z-coordinate (or the height) after walking due south

So, the point where you stand after walking due south has a coordinate of (100, y', z'). Moreover,

z' = 1,400 - 0.05(100)^2 - 0.01(y')^2
\\ \boxed{z' = 1350 - 0.01(y')^2}

Since the y-coordinate decreases after walking due south and z' = 1350 - 0.01(y')^2,

y'  \leq 120\\ \Rightarrow (y')^2 \leq 120^2 = 14,400\\ \Rightarrow -0.01(y')^2 \geq -0.01(14,400) = -144\\ \Rightarrow z' = 1,350 - 0.01(y')^2 \geq 1,350 - 0.01(14,400) = 1,206\\ \Rightarrow \boxed{z' \geq 1,206}

So, the height after walking due south exceeds 1,206 meters, which is the previous height before walking due south. Therefore, if you walk due south from point with coordinates (100, 120, 1206), you are ascending.

Hello can someone help me please
Nadusha1986 [10]

Add the three different amounts she gets to find the total:

450 + 300 + 500 = 1250 mg total.


1250 is greater than  1200, so yes, she is getting enough.
