Answer:
a) -36
b) y = -36x +34
Step-by-step explanation:
a) The slope is found using the derivative of the function.
f'(x) = dy/dx = 0 -9(2x) = -18x
Then at x=2, the slope is ...
f'(2) = -18·2 = -36
___
b) The point-slope form of the equation can be written as ...
y = -36(x -2) -38
Simplifying to slope-intercept form, we get ...
y = -36x +34
Answer: station X
Step-by-step explanation:
Because it was 3.08 the rest were lower
Answer:
D. 45
Step-by-step explanation:
<u>All angles</u><u> </u><u>h</u><u>a</u><u>v</u><u>e</u><u> </u><u>t</u><u>o</u><u> = 180°</u>
60 + 75 + <RVE = 180°
135 + RVE = 180°
180 - 135 = <u>4</u><u>5</u><u>°</u><u> </u><u>R</u><u>V</u><u>E</u>
<u>R</u><u>V</u><u>E</u><u> </u><u>=</u><u> </u><u>4</u><u>5</u><u>°</u>
<u>A</u><u>n</u><u>o</u><u>t</u><u>h</u><u>e</u><u>r</u><u> </u><u>w</u><u>a</u><u>y</u><u> </u><u>t</u><u>o</u><u> </u><u>c</u><u>h</u><u>e</u><u>c</u><u>k</u><u> </u><u>y</u><u>o</u><u>u</u><u>r</u><u> </u><u>a</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u>
Add all of the angles, and it should equal 180°
60 + 75 + 45 = 180°
Correct!
Remark
You can get it just by looking at the net. It has 6 squares. Each square has a side of 5 cm by 5cm. Find the area of 1 square and multiply by 6.
Step One
Find the area of one square.
<u>Formula</u>
Area = s^2
<u>Solve</u>
Area for 1 square = s^2 = 5^2 = 25 cm^2
Step Two
Find the area for six squares.
Area of the net = 6*Area of one square = 6 * s^2
6*s^2 = 6 * 25
Area = 150 cm^2
