Step-by-step explanation:
-35 x - 625 = 21875 so positive
263 x 0 = 0 so zero
-21 x 451 = - 9471 so negative
-350 x 89 = - 31150 so negative
Answer:
2 feet
Step-by-step explanation:
1 pm = 8ft
<em> 2pm = 6ft </em>The rate of change is 2
<em> 3pm = 4ft </em>
4pm = 2ft
Answer:
21, 8
Step-by-step explanation:
The second endpoint is of the form (X, 8) since it's parallel to the x axis.
Given the congruence of the two segments, we can tell that its length is 16 units (since 
)
At this point the two possible endpoints for the segment are 
or 
. The fact that the segment has to sit in the first quadrant rules out the first option (it's endpoint will be at (-11, 8) which will set most of it in the second quadrant) and we're left with (21, 8)
Answer:
SA = 7.08 in²
Step-by-step explanation:
We can use the following method to solve the given problem
SA = 2B + LA
Where LA
LA = 4.72* 0.05* 15= 3.54
And
C = 2πr
Where
C = 4.72in
π = 3.14
Substituting, we have
4.72 = 2*3.14*r
Making r the subject of formula
r = 0.75in
Solve for the area of CD
A = πr²
Substituting the values we have
A = 3.14 *(0.75)²
A= 1.77 in²
Solving for surface area of the stack
SA = 2(1.77) + 3.54
SA = 7.08 in²
The area of the sector in the circle can be calculated using the formula:
A = <span>π r</span>² θ / 360
where r is the radius and θ is the area subtended by sector. So,
A = π (10)² (37/360)
The answer is the first option.
