Find the value of w and then x. Round lengths to the nearest tenth and angle measures to the nearest degree.
VARVARA [1.3K]

Answer

w=7.6

x=43.7

Step-by-step explanation:

To solve for w you can use Sin(x)=\frac{Opposite}{Hypotenuse}  which would basically be Sin(50)=\frac{w}{10} then solve. Multiply the ten on both sides so you have 10*Sin(50)=w and your final answer is 7.6

To solve for x you can also use Sin(x)=\frac{7.6}{11} then just use Inverse of Sin^-1

The answer is x=43.7

Find the values of p and q such that 4x^2+12x=4(x+p)^2-q
-Dominant- [34]

Answer:

p = 1.5 and q = 9

Step-by-step explanation:

Expand the right side then compare the coefficients of like terms on both sides, that is

4(x + p)² - q ← expand (x + p)² using FOIL

= 4(x² + 2px + p²) - q ← distribute parenthesis

= 4x² + 8px + 4p² - q

Comparing coefficients of like terms on both sides

8p = 12 ( coefficients of x- terms ) ← divide both sides by 8

p = 1.5

4p² - q = 0 ( constant terms ), that is

4(1.5)² - q = 0

9 - q = 0 ( subtract 9 from both sides )

- q = - 9 ( multiply both sides by - 1 )

q = 9

Original price of a cell phone is 154.99$ the discount is 20% what's the price off
Irina-Kira [14]
To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!
