Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
Answer:
27
Step-by-step explanation:
4 times 4 is 16
2 boxes in the middle
4 tiny boxes in each one in the middle
1 entire one on the outside
1+4+4+2+16= 27
I believe the answer is 23.52 because if u add 19.60 to 20% thats what u get
2x+y>3 describes the low end, presuming that you have defined to mean the number of field goals and to mean the number of free throws. yet your best game was 15, so the values must also satisfy 2x+y
Answer:
483.56 square milimeters
Step-by-step explanation:
In the above question, we obtain the following information:
Slant height = 15mm
Radius = 7mm
π = 3.14
Since we are given the slant height ,
the formula for surface area of a cone = πrl + πr²
= πr (l + r)
= 3.14 × 7(15 + 7)
= 3.14 × 7( 22)
= 21.98(22)
= 483.56 square milimeters
