VARVARA [1.3K]

Answer:

(D)56.4

Step-by-step explanation:

According to the question, Let AB=10, AC=12 and m∠B=90°.

Thus, from ΔABC, using trigonometry, we have

\frac{AB}{AC}=sinx

\frac{10}{12}=sinx

\frac{5}{6}=sinx

sinx=0.83

x=sin^{-1}(0.83)

x=56.4

Therefore, at x=56.4 the wire meet the ground.

Please help, i need to raise my grade <br>solve for v​
zhenek [66]

Answer:

2(s-c)/ a^2 =  v

Step-by-step explanation:

s = 1/2 a^2 v+c

Subtract c from each side

s -c = 1/2 a^2 v+c-c

s-c = 1/2 a^2 v

Multiply each side by 2

2(s-c) = 2* 1/2 a^2 v

2(s-c) = a^2 v

Divide each side by a^2

2(s-c)/ a^2 = a^2 v /a^2

2(s-c)/ a^2 =  v

navik [9.2K]

Answer:

The weighted mean grade is 78.62                    

Step-by-step explanation:

We are given the following in the question:

Regular exam score = 79, 74, and 73

Weightage of regular exam = 12%

Final exam grade = 66

Weightage of final exams = 17%

Course project grade = 88

Weightage of project = 10%

Homework grade = 93

Weightage of homework = 37%

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean of regular exam scores =

Mean =\displaystyle\frac{226}{3} = 75.33

Weighted mean grade

w = \dfrac{\sum wx}{\sum w}

\displaystyle\sum wx =\displaystyle\frac{12}{100}\times 75.33 + \frac{17}{100}\times 66 + \frac{10}{100}\times 88 + \frac{33}{100}\times 93\\\\\displaystyle\sum wx = 59.75\\\\\sum w = 0.12 + 0.17 + 0.10 + 0.37 = 0.76\\\\w = \frac{59.75}{0.76} = 78.62

The weighted mean grade is 78.62
