X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13
if any questions please ask
Answer: 0.648637
Explanation:
e^3x = 3 + 4
e^3x = 7
3x = In (7)
X = 0.648637
The right angle triangles are:
Triangle A has two acute angles and one ninety degree angle
Triangle d has two acute angles and one ninety degree angle.
<h3>What are right triangles?</h3>
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees. A right angled triangle is a triangle in which one of its angles measure 90 degrees.

U = ( -8 , -8)
v = (-1 , 2 )
<span>the magnitude of vector projection of u onto v =
</span><span>dot product of u and v over the magnitude of v = (u . v )/ ll v ll
</span>
<span>ll v ll = √(-1² + 2²) = √5
</span>
u . v = ( -8 , -8) . ( -1 , 2) = -8*-1+2*-8 = -8
∴ <span>(u . v )/ ll v ll = -8/√5</span>
∴ the vector projection of u onto v = [(u . v )/ ll v ll] * [<span>v/ ll v ll]
</span>
<span> = [-8/√5] * (-1,2)/√5 = ( 8/5 , -16/5 )
</span>
The other orthogonal component = u - ( 8/5 , -16/5 )
= (-8 , -8 ) - <span> ( 8/5 , -16/5 ) = (-48/5 , -24/5 )
</span>
So, u <span>as a sum of two orthogonal vectors will be
</span>
u = ( 8/5 , -16/5 ) + <span>(-48/5 , -24/5 )</span>
Answer:
12 different types of sandwich could be made.
Step-by-step explanation:
Since I am making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3 kinds of meat, to determine how many different sandwiches could I make the following calculations must be performed:
Bread x cheese x meat = X
2 x 2 x 3 = X
4 x 3 = X
12 = X
Therefore, 12 different types of sandwich could be made.
