Answer:

a. AB = 3.4 ft

b. AE = 1.6 ft

Step-by-step explanation:

SOH CAH TOA reminds you of the relationship between trig functions and right triangle sides.

a. Cos = Adjacent/Hypotenuse

cos(28°) = BE/BA = 3 ft/BA

Multiplying by BA and dividing by cos(28°), you get ...

BA = (3 ft)/cos(28°) ≈ 3.4 ft

___

b. Tan = Opposite/Adjacent

tan(28°) = AE/BE = AE/(3 ft)

Multiplying by 3 ft, you get ...

AE = (3 ft)·tan(28°) ≈ 1.6 ft

Answer:

5/4in

Step-by-step explanation:

The initial length:

1 ft = 12 in

8 ft = 8 * 12 in

= 96 in

The final length:

7 ft 10 3/4 in = 7 ft + 10 in + 3/4 in

= 7 * 12 in + 10 in + 3/4 in

= 84 in + 10 in + 3/4 in

= 94 in + 3/4 in

The final length:

96 in - 94 in - 3/4 in = 2 in - 3/4 in = 8/4 in - 3/4 in = 5/4 in

The slope of the line in the graph is 4. Fill in the y intercept. Choose the correct equation in the form y = mx + b The y inter

nikitadnepr [17]

Answer:

$\rm\implies y = 4x + 3$

Step-by-step explanation:

Given :-

The slope of the line in the graph is 4.

And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 .

Slope Intercept Form :-

$\rm\implies y = mx + c$

Substituting the respective values :-

$\rm\implies y = 4*x + 3 \\\\\rm\implies y = 4x + 3$

Hence the equation of line is y = 4x + 3
