Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle
Answer:
6 matches
Step-by-step explanation:
Let’s call the teams A B C D
A will play B C D = 3 matches
B will play only C and D as it already played A, making 2 matches
C will play D, making 1 match
D has already played all
Total number of matches is thus 3 + 2 + 1 = 6 matches
Answer:
Step-by-step explanation:
Lupita brought seven pounds of pretzels at a local wholesaler for 16.80. This means that the rate at which she bought one pound of pretzel at the local wholesaler would be
16.80 / 7 = $2.4 per pounds of pretzels
Her friend, Charles about 5 pounds of pretzels at the supermarket 12.75. This means that the rate at which Charles bought one pound of pretzel at the supermarket would be
12.75 / 5 = $2.55 per pounds of pretzels
Charles's reasoning is wrong because the rate at which he bought one pound of pretzel is higher than that of Lupita's
Analytically show that the equation below represents trigonometric
32x^2 3*sqrt2x - 8x^3 (it’s the second option in the photo)
