For the answer to the question <span>What is sin θ ? </span>(8, -15) is in quadrant IV.
Draw the right triangle.
hypotenuse = √(8² + 15²) = 17
<span>sinθ = -15/17
</span>
Just draw the graph for reference.
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
Step-by-step explanation:
A. Dad = 50, Mum = 47, Sister = 22
me = 19
Total Sum = 50 + 47 + 22 + 19
= 136
√136 = 11.662.
B. + 1435 797 202 = 40
√40 = 6.33
C. BRYAN = 2 + 18 + 25 + 14 = 59
√59 = 7.68.
Answer:
The answer is "
".
Step-by-step explanation:
Given value:
They understand that, by using algebraic expressions laws, they subtract that inverse whenever we subtract powers with the same base. Every exponent's core is 2, therefore we subtract:
They have a shared denominator. It's least that is equally divided
among 8 or 2 is 8:
This gives us:
As rational notation is written as extremists, that root was its denominator as well as the power seems to be the numerator.
Which means 8 is the root and 5 the force that gives us:
Answer:
Step-by-step explanation:
Assume as a basis the final mixture is 1000 mL. That means 399 mL of alcohol
Let x = mL of Soln A and y = mL of soln B.
x = 2y.
Now x + y = 1000
and 0.2x + 0.17y = 399
but x = 2y so 0.4y + 0.17y = 399
0.57y = 399.
y = 700 mL (That is your mL of solution B)
The sequence 20 , 11 , 2 , -7 is an arithmetic sequence.
The common difference is (20 - 11) = (11 - 2) = (2 - -7) = 9
The common difference is 9.
