Answer:
15 cm
Step-by-step explanation:
B. 18
Explanation
The dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number
it is given by.
so, we can find the dot product by multiplying the corresponding values in each vector and adding them together
Step 1
get the dot product
let
then
therefore, the answer is
B. 18

Answer:
third option: PQ = 1/4(YZ)
Step-by-step explanation:
By the Midsegment Theorem, a midsegment is 1/2 the side across it. Using this, we can say:
In triangle XYZ, AB = 1/2(YZ)
And in triangle XAB, PQ = 1/2(AB)
We can substitute AB into the second equation to get:
PQ = 1/2(1/2(YZ))
PQ = 1/4(YZ)
This is the third option.
Answer:
Q7) 25.5
Q8) 25
Q9) 10
Q10) 12.7
Q11) 34
Q12) 24
Step-by-step explanation:
Q7) c² = a² + b²
x² = 18² + 18²
x = √18² + 18²
x = 18√2 = 25.5
Q8) c² = a² + b²
x² = 20² + 15²
x = √20² + 15²
x = 25
Q9) c² = a² + b²
26² = 24² + x²
x = √26²-24²
x = 10
Q10) c² = a² + b²
x² = 9² + 9²
x = √9² - 9²
x = 9√2 = 12.7
Q11) c² = a² + b²
x² = 30² + 16²
x = √30² + 16²
x = 34
Q12) c² = a² + b²
25² = x² + 7²
x = √25² - 7²
x = 24

Because this is asking for men, we only look at males. we see that the first bar is barely under halfway between 15 and 20, meaning that it is 17. now the second bar is also barely under halfway between 5 and 10, so it is 7. now 17+7=24
