Answer:
54deg
Step-by-step explanation:
We need to compute the inverse cosine of 10/17. I can't do it by hand, so I used a calculator and it arrived at ~53.97deg which is 54deg rounded to the nearest tenth.
Answer:
Adult is $12 and child is $7
Step-by-step explanation:
Adult=x and Children=y
first day: 4x+1y=55
second: 3x+2y=50
Get one letter the same but opposite
(4x+1y=55) times that by -2
-8x+-2y=110
3x+2y=50
minus all of that u get
-5x=60
divide 60 by 5
x=12
fill in X
3(12)+2y=50
36+2y=50
-36 -36
2y=14
/2 /2
y=7
Answer:
8x^8/3 y^4 - The first option
Step-by-step explanation:
The first thing we need to do is the exponent outside the bracket and leave the 8 till last, because exponents always come before multiplying coefficients. When an term with an exponent is multiplied by another exponent outside a bracket, the exponents of both terms are multiplied by the exponent outside the bracket.
This means that the expression is now:
8(x^2*4/3 y^3*4/3)
First we can so the x term. The x term already has an exponent of 2, so the 2 is multiplied by the 4/3 exponent outside the bracket. 2*4/3 = 8/3, so the x term is now: x^8/3
The same happens to the y term: 3*4/3 simplifies to 4, so the y term is now y^4.
So now our expression is:
8(x^8/3 y^4)
Now the 8 outside the bracket simply multiplies on to the whole term so we finish with:
8x^8/3 y^4 - The first option.
Hope this helped!
