There is a typo somewhere because the answer is -2
Step by Step:
-|-5+3-2|+2
-|-4|+2
-4+2
=-2
A. theta = 210 (180 + 30) cos 30 = sqr(3)/2 sin 210 = -1/2
b. theta = 300 (360-60) tan 300 = - sqr(3)
c. sin = 1/2, cos = sqrt(3)/2, tan theta = 1/sqr(3), theta = 30
ANSWER
C. 7
EXPLANATION
We want to evaluate
We use the order of operations PEDMAS.
Dealing with the parenthesis first,we have
Note that:
and
Our expression now becomes:
Next, we add to get:
We finally subtract to get,
The correct answer is C
Answer: c = 520
Step-by-step explanation:
f(2) = 578 means that when x = 2, the value is equal to 578. We will plug these knowns in and then solve for c.
Given:
f(x) = 4x³ + 7x² - x + c
Substitute:
578 = 4(2)³ + 7(2)² - (2) + c
Distribute:
578 = 4 * 2³ + 7 * 2² - 2 + c
Raise to the power of 3 and 2:
578 = 4 * 8 + 7 * 4 - 2 + c
Multiply:
578 = 32 + 28 - 2 + c
Add:
578 = 60 - 2 + c
Subtract:
578 = 58 + c
Subtract 58 from both sides:
520 = c
Reflexive property:
c = 520
