2 · 7.5 + 2 · 11 = 15 + 22 = 37
The logarithmic expression is
To expand the expression we have to use some properties of logarithm.
We know that 
By using this property we can write,
Square root means to the power 1/2, so for 
, we can write 
.
Now we have to use another property of logarithm.
We know that, 
So we will use this property to 
Now we have to use another property of logarithm.
We know that, 
By using this property we can write,
This is the required aswer here.
Answer:
Volume= 540 ft^3
Step-by-step explanation:
Since volume= length times Width times height, you do 3 times 6 times 30= 540 ft^cubed.
Answer:
The figure will result is cone ⇒ B
Step-by-step explanation:
<em>When a </em><em>right triangle is rotated about its vertical leg 360°</em><em>, then it formed </em><em>a cone</em><em> its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle</em>
<em />
In the given figure
∵ Triangle TRE is a right triangle
∴ The horizontal leg is RE
∴ The vertical leg is TR
∵ The triangle is rotated around the horizontal leg RE 360°
∴ It formed a cone its radius = TR and its height = RE
∴ The figure will result is the cone
