Answer:
B. 0.69
Step-by-step explanation:
Law of Cosines: cos A = (b² + c² - a²) / 2bc
cosθ = (7² + 11² - 8²) / 2*7*11 = 106/154 = 0.688 ≈ 0.69
Answer:-32 I THINK IM NOT 100 PERCENT POSITIVE
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Differentiate the function and set it to zero:
f'(x) = -10x + 13
0 = -10x + 13
x = 1.3 seconds
Plug the x value into f(x):
f(1.3) = -5(1.3)^2 + 13(1.3) + 6 = 14.45 meters
Answer:
Option C. 10 square inch
Step-by-step explanation:
Net of a prism is shown on the coordinate plane. We have to calculate the surface area of the prism.
To calculate the surface area of the net we will calculate the area of the four large rectangles and two squares given in the picture.
Total surface area of the net = 2× small squares + 4×large rectangles
= 2×(1×1) + 4×(1×2) = 2 + 8 = 10 square inch.
Therefore option C. 10 square inch is the answer.
Hi there! :)
<u>Answer:</u>
x = -2
Step-by-step explanation:
<u>5</u> - 3x = 11
Subtract "5" from each side of the equation → 11 - 5 = 6
<u>-3</u>x = 6
Divide each side of the equation by "-3" → 6 ÷ -3 = -2
<u>x = -2</u>
There you go! I really hope this helped, if there's anything just let me know! :)
