ABC is the middle line of MN in an equilateral triangle. If AB = 8 cm, then find the perimeter MBN.
qaws [65]

Answer:

the answer is 12

Step-by-step explanation:

since the triangle is equilateral meaning all side of ABC is equal to each other AB= BC = AC= 8cm and MN is the middle line that divides AB and BC by two

thus, MB =BN= 4 cm. MN is the middle line thus will also be equal to the half of AC  meaning MN=AC/2= 4cm. and perimeter  is MBN = MN+MB+BN= 4cm+4cm+4cm =12cm

Evaluate the expression. r = , v = , w = v ⋅ w
FromTheMoon [43]

Answer:

v . w= -13

Step-by-step explanation:

Evaluate the expression: v ⋅ w Given the vectors: r = <8, 1, -6>; v = <6, 7, -3>; w = <-7, 5, 2>

Solution

Given the vectors:

r = <8, 1, -6>

v = <6, 7, -3>

w = <-7, 5, 2>

If you're asking about the dot product.

The dot product is a scalar. It is the sum of the product of the corresponding components.

v.w = (6*-7) + (7*5) + (-3*2)

= -42+35-6

= -13.

What is the simplest form of the radical expression?
BaLLatris [955]
I believe the equation is
4 \sqrt[4]{2x} + 6  \sqrt[4]{2x}
In this case, you would simplify it by adding them together.
4 \sqrt[4]{2x} + 6  \sqrt[4]{2x} = 10  \sqrt[4]{2x}
And can even be changed to an exponential equation:
10(2x)^{ \frac{1}{4} }
