Let's check the dot product .
v.w = 5(4)-2(10) = 20 -20 =0
So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.
And the y component of w is 10.
So correct options are first and third .
Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A

Answer:
162
Step-by-step explanation:
Given algebraic expression:
To:
- Evaluate this expression,with : x = 6
Solution:
Simplify by plugging x = 6
- 4(6)²+3(6)
- 4(36) + 18
- 144 + 18
- 162
<em>We can conclude:</em>
By evaluating this expression by x = 6 , the answer will be 162.
