Answer: 4
Step-by-step explanation: Using Sine, Cosine, and Tangent, you use 8 as the hypotenuse and put your 60 w/ you Cos, so it will read cos60*=adj/8. Then you'll multiply both sides by 8, so it will be 8*cos60=adj. So, the cosine of 60 is 1/2, you multiply that by 8, then that equals 4, I hope that helps!
Answer:
7/12

fraction of field is planted potatoes = 1 - sum of fraction of farm planted with maize and beans
sum of fraction of farm planted with maize and beans =
1 - 5/12 = 7/12
Answer:
71 baskets of 3 apples.
Step-by-step explanation:
From each of the 28 baskets of 6 you can get 6/3 = 2 baskets of 3.
From each of the 5 baskets you can get 9/3 = 3 baskets of 3.
Therefore:-
From the 28 baskets you can create 28 * 2 = 56 baskets of 3.
From the 5 baskets of 9 you can get 5 * 3 = 15 baskets of 3.
Total 15 + 56 = 71.
The correct answers are: 1/2, 2 and -2.
To get this, factor f(x)
f(x)=2x^3-x^2-8x+4
f(x)= (2x^3-x^2) - (8x -4)
f(x)= (2x-1)(x^2) + (2x-1)(-4)
f(x)= (2x-1)(x^2-4)
f(x)= (2x-1)(x-2)(x+2)
2x-1=0
2x=1
x=1/2
x-2=0
x=2
x+2=0
x=-2
Answer:
Option D is correct.
1/4 completes the square.
Step-by-step explanation:
To complete the square for a quadratic function, we require a third term that will enable the solutions of the quadrstic equation to be 2 repeated roots.
For that to be so for the quadratic equation
ax² + bx + c = 0,
b² has to be equal to 4ac
For this question, x² - x + c
From b² = 4ac
c = (b²/4a)
a = 1
b = -1, b² = 1
c = ?
c = (1/4)
Hence, (1/4) is the number that must be added to the expression to complete the square.
Hope this Helps!!!
