we are given
we have to find theta
so, firstly we can write sin in terms of cos
now, we can set it equal
Since, both sides are cos
so, we can set angles equal
now, we can solve for theta
we get
..............Answer
Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2
I did it for you but please look it up, understand and memorize it ;)
Answer:
g
Step-by-step explanation:
42 cups in to pints is 21 so g
Answer:
Option B.
Step-by-step explanation:
Remember that the profit is defined as the difference between the revenue and the cost.
So, having a profit y = 0 means that the woodworker did not win nor lose anything.
Then the zeros of the function, the values of x such that the graph intersects the x-axis, are the prices such that she does not win nor loss anything.
In the graph we can see that the zeros are at:
x = 15 (the first one)
x = 70 (the second one)
so the zeros are at x = 15 and x = 70, and these are the prices such that the profit is zero, so at these prices she does not make nor lose money.
The correct option is B.
Answer:
x= −1
/2 or x=4
Step-by-step explanation:
This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step
2x^2−7x=4
<u>Step 1: Subtract 4 from both sides.
</u>
2x^2−7x<u>−4 </u>=4 <u>−4
</u>
2x^2−7x−4=0
<u>Step 2: Factor left side of equation.
</u>
(2x+1)(x−4)=0
<u>Step 3: Set factors equal to 0.
</u>
2x+1=0 or x−4=0
x= −1
/2 or x=4
(BTW, there are supposed to be two answers, it's factoring)
Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)
