Answer:
CD=10.15m
Step-by-step explanation:
<u>Find the distance of BC.</u>
Tan(40)=55/BC
BC=65.55m
<u>Find the distance of BD.</u>
Tan(36)=55/BD
BD=75.70m
<u>Use BC and BD to find CD</u>
BD-BC=CD
75.70-65.55=CD
CD=10.15m
Volume of a cylinder= (height) x area of the base (circle)
We know the height = 160 cm (given), let's find the radius of the base.
The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm
Area of circle = πR²=π(13.993)² = 615.128 cm²
Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³
Answer:
2.5 is less than 1,950.
Step-by-step explanation:
The decimal place is at the end of 1,950.
The decimal place is in the middle of the 2 and the 5.
Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.
You can subtract both values.
1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.
0 < 1,947.50.
Therefore, 2.5 < 1,950
Answer:
150x^2+2340x-50000
Step-by-step explanation:
5[6x(5x+78)-10000]
5[30x^2+468x-10000]
150x^2+2340x-50000
It is true if two vectors point in opposite directions. This means their cross product must be zero.
<h3>What is cross product?</h3>
Cross product is a vector product of two vectors in the three dimensional vector space.
In the case when the two vectors point in opposite directions so there cross product should be zero.
Impact on two points:
In the case when the two vectors point in opposite directions so there cross product should be zero.
Like
A*B = [A][B] sin
Here theta is be the angle that lies between them
So,
A*B = [A][B] sin 180
So, A*B = 0
hence, the given statement is true.
