Step-by-step explanation:
Question 4
we have two sides and an angle so we should use law of cosines to solve for c
[tex]7=\sqrt{5^2+c^2-2*5*c*cos(35)}\\\\49=25+c^2-10*c*cos(35)\\25=c^2-8.19152044289c\\c^2-8.19152044289-25=0\\[/tex]
(using the quadratic formula)
c=10.48131
To solve for b use the law of cosines again
[tex]5=\sqrt{7^2+10.48131^2-2*7*10.48131*cos(B)\\[/tex]
B=24.1858343432

2a:
[tex]a^6+\frac{64}{125} =(a^2)^3+(\sqrt[3]{\frac{64}{125} })^3[/tex]
Now, we can apply the sum of cubes formula that goes:
[tex]x^3+y^3=(x+y)(x^2-xy+y^2)[/tex]
Therefore,
[tex](a^2)^3+(\sqrt[3]{\frac{64}{125} })^3=(a^2+\frac{4}{5})(a^4-\frac{4a^2}{5}+(\frac{4}{5} )^2)[/tex]
[tex]=(a^2+\frac{4}{5})(a^4-\frac{4a^2}{5}+\frac{16}{25} )[/tex]
---------------------------------------------
2b:
[tex]16x^8-y^4=(4x^4)^2-(y^2)^2[/tex]
Now, we can apply the difference of two squares formula that goes:
[tex]x^2-y^2=(x+y)(x-y)[/tex]
Therefore,
[tex](4x^4)^2-(y^2)^2=(4x^4+y^2)(4x^4-y^2)[/tex]
You can apply the difference of two squares formula again:
[tex](4x^4+y^2)(4x^4-y^2)=(4x^4+y^2)((2x^2)^2-y^2)[/tex]
[tex](4x^4+y^2)(4x^4-y^2)=(4x^4+y^2)(2x^2+y)(2x^2-y)[/tex]
if Vera is 3 times as old as Zoe and 2 times as old as Paul. And the sum of their ages is 33. what is Zoe's age?
Answers
Answer:
Zoe is 6 years old.
Step-by-step explanation:
Vera - V
Zoe - Z
Paul - P
V = 3Z
Z = [tex]\frac{1}{3}V[/tex]
V = 2P
P = [tex]\frac{1}{2}V[/tex]
V + Z + P = 33
[tex]V + \frac{1}{3}V + \frac{1}{2}V = 33[/tex]
[tex]\frac{6}{6} V + \frac{2}{6}V + \frac{3}{6}V = 33[/tex]
[tex]\frac{11}{6}V = 33[/tex]
[tex]V = 33 * \frac{6}{11}[/tex]
[tex]V = 3 * \frac{6}{1}[/tex]
[tex]V = 18[/tex]
V = 3Z
18 = 3Z
Z = 6

You are a prisoner sentenced to death. The emperor (who has sentenced you) offers you a chance to live by playing a simple game. He gives you 10 black marbles, 10 white marbles, and 2 empty bowls. He then says, "Divide these 20 marbles into these 2 bowls. You can divide them any way you like as long as you place all the marbles in the bowls. Then I will blindfold you, and ask you to choose a bowl, and remove ONE marble from that bowl you have chosen. You must leave the blindfold on the entire time, and must remove the first marble you touch. If the marble is white you will live, but if the marble is black, you will die."

−23a+18−16a−34
Answers
Answer:
-39a - 16 is not the answer, it's -5/6a - 5/8
Step-by-step explanation:
Took the test and got it incorrect.
Answer:
-5/6a - 5/8
Step-by-step explanation:
There is a massive difference between -2/3a & -23a.
Same goes for 1/8 & 18, -1/6a & -16a, and -3/4 & -34.
My earlier answer, -39a - 16, IS correct for the question you wrote. What was incorrect was the question.
It is important to write the question properly because
−23a+18−16a−34
and
−2/3a+1/8−1/6a−3/4
will have very different answers.
In conclusion, make sure you write your question correctly. It's unfair to others genuinely trying to help who then are blamed for supplying the "wrong answer" by others who also copied and pasted from their school work.
If you had written, −2/3a+1/8−1/6a−3/4, then the answer would be -5/6a - 5/8.

Step-by-step explanation:
Answer:
x=3/2±(√11)2
x=1.5+1.65831i
x=1.5−1.65831i
Find the Solution for
2x^22−6x+10=0
using the Quadratic Formula where
a = 2, b = -6, and c = 10
x=(−b±√(b^2−4ac))/2a
x=(−(−6)±√((−6)2−4(2)(10)))2(2)
x=(6±√(36−80))/4
x=(6±√−44)/4
The discriminant b^2−4ac<0
so, there are two complex roots.
Simplify the Radical:
x=(6±2√11 i)/4
x=6/4±(2√11 i)4
Simplify fractions and/or signs:
x=3/2±(√11)2
which becomes
x=1.5+1.65831i
x=1.5−1.65831i
