The answer is A and B. To simplify 28=y^2 for have to square root each side in order to get rid of the exponent value. Since the square root is not a whole number value. The answer stays as 28 square rooted. But the alternative answer is 5.2915 so also answer A.

Q||R

(11x-28) +(7x-8) = 180 ( co. interior.angle)
11x -28+7x-8 =180
11x-7x-28-8=180
4x-36=180
4x=180+36
4x = 216
x = 216/4
x = 54

I need to rewrite d and h without the use of fractional or negative exponents by using radicals, how I do that???

jolli1 [7]

Answer:

The pencil marks on your page show you exactly how to do that.

Step-by-step explanation:

Take advantage of two rules of exponents:

$\sqrt[n]{x}=x^{\frac{1}{n}}\\\\x^{-n}=\dfrac{1}{x^{n}}$

$(d)\quad x^{\frac{-1}{5}}=\dfrac{1}{x^{\frac{1}{5}}}=\dfrac{1}{\sqrt[5]{x}}\\\\(h)\quad x^{\frac{-2}{11}}=\dfrac{1}{x^{\frac{2}{11}}}=\dfrac{1}{\sqrt[11]{x^{2}}}$

An airplane is traveling due east with a velocity of 583 miles per hour. The wind blows at 75 miles per hour at an angle of S58°

ASHA 777 [7]

Answer:

D. 647.8 miles per hour; S86.5°E

Step-by-step explanation:

We assume the wind direction is supposed to be S58°E. Then the bearing of the plane measured clockwise from north is 90°, and the direction the wind is blowing toward has a bearing of 122°. The resultant speed and direction is the sum of the two vectors, which is easily found using a suitable calculator:

583∠90° + 75∠122° = 647.8∠93.5°

The bearing of 93.5° translates to the direction S86.5°E.

_____

An angle east of south is subtracted from 180° (south) to find the equivalent bearing.
