trasher [3.6K]

Answer:

12º

Explanation:

The angle Marcel's code adjust the shot can be calculated using the cosine law:

$C^2=A^2+B^2-2|A||B|cos(c)$

For the triangle of the figure:

C = 15m
A = 50m
B = 60m
c = ? (the unknown angle)

Substitute and solve for c:

$(15m)^2=(50m)^2+(60m)^2-2(50m)(60m)cos(c)\\\\\\225=2500+3600-6000cos(c)\\\\6000cos(c)=2500+3600-225=5,875\\\\cos(c)=5,875/6000\approx0.97917\\\\c=arccos(0.97917)\approx12\º$

Can someone please help me:! )

GenaCL600 [577]

Answer:

u=-5

Step-by-step explanation:

Slope is y(2)-y(1)/x(2)-x(1). So, your equation is u-10/-2-1. -2-1=-3, so the top number has to be negative to get a positive and has to be 5 times more than three. So, the numerator for the slope would be -15, because -15/-3=5. So, u is equal to -15-10. Therefore u equals -5.

(hope this helps :P)

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???

Dmitriy789 [7]

Answer:

2/45

Step-by-step explanation:

0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: $(\frac{1}{10} )(\frac{4}{9} )$ . Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
