Calculate the length AB

Answers

Answer:

14.004m

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

Tan theta = opposite/adjacent

Given

AB = opposite

BC = adjacent = 20cm

theta = 35 degrees

Substitute

tan 35 = AB/20

AB = 20tan35

AB = 20(0.7002)

AB = 14.004cm

Hence the length of AB is 14.004m

Some number subtracted by -6 is 41. Multiply this number by-3. Then divide
this number by -4. What is the final number?

Answers

Answer:

The final number is 26.25.

Step-by-step explanation:

First, solve the beginning sentence.

"Some number" can be represented by x

x - (-6) = 41    

x + 6 = 41

x = 35

Next, solve the second sentence

35*(-3) = -105

Finally, the last sentence

(-105)/(-4) = 26.25

2: 1.30

Step-by-step explanation:

Hope this helps

Answer:

0.80 and 1.30

Step-by-step explanation:

0.80, 1.05, 1.30, 1.55, 1.80, 2.05

... + 0.25 = 1.05

= 1.05 - 0.25

= 0.80

0.80 + 0.25 = 1.05

1.05 + 0.25 = 1.30

1.30 + 0.25 = 1.55

1.55 + 0.25 = 1.80

1.80 + 0.25 = 2.05

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.

Answers

Answer:

Step-by-step explanation:

Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

Solve y = f (x) for x. Then find the input when the output is -3.
f(x) = 3x+5

Answers

Answer:

f(-3)= -4

Step-by-step explanation:

Given function in the question is,

f(x) = 3x + 5

Here, values of 'x' are the input values of the function.

And the values of the function f(x) by substituting the values of 'x' are the output values.

If the output value of the function 'f' is -3,

-3 = 3x + 5

3x = -3 - 5

x = [tex]-\frac{8}{3}[/tex]

Therefore, for the input value x = [tex]-\frac{8}{3}[/tex], output value of the function will be f(x) = -3.
