Answer:
576 cm cubed
Step-by-step explanation:
9 x 16 x 4 = 576
The grade is the ratio of rise to run, i.e. the slope aka the tangent.
Answer: (a) 6 degrees
For part b, the road is the hypotenuse c of a right triangle whose tangent of the small angle is 1/10. The height h or rise is the side opposite the small angle.
We could just take the sine of the angle we got but let's get it from the tangent exactly.
Dividing by squared cosine
Answer: (b) Rise of 0.199 km
1 kilo=1000 meters.
The race is 5,000 meters total.
5000 divided by 1 station every 400 miles.
5000/400=12.5
12.5 water stations!
<em />I dont know if you're supposed to round but there you go!
Answer:
y-7=3(x-9)
Step-by-step explanation:
It appears they want your answer in point-slope form, which is identified by the equation y-y1=m(x-x1)
Step 1: Find the slope (m)
m=(y2-y1)/(x2-x1)
m=(-8-7)/(4-9)
m=(-15)/(-5)
m=3
The slope is m=3
Step 2: Plug in m, y1, and x1
y-y1=m(x-x1)
y-7=3(x-9)
Therefore our final equation is y-7=3(x-9)
The area of the garden needs to be greater than 400 square feet but less than 600 square feet
