Answer:

4 3/8

Step-by-step explanation:

8 × 1 + 7 = 15/8

3 × 2 + 1 = 7/3

Now, we'll multiply both numerator and denominators.

(numerators) 15 × 7 = 105

(denominators) 8 × 3 = 24

= 105/24

Now, we'll find the simplest form of 105/24

= 4 3/8

Answer:

y = \frac{\pi}{3}

Step-by-step explanation:

using the addition formula for sine

sin(x + y) = sinxcosy + cosxsiny

then

sinxcosy + cosxsiny = \frac{1}{2} sinx + \frac{\sqrt{3} }{2} cosx

for the 2 sides to be equal , then

cosy = \frac{1}{2} and siny = \frac{\sqrt{3} }{2}

then

y = cos^{-1} (\frac{1}{2} ) = \frac{\pi }{3}

and

y = sin^{-1} ( \frac{\sqrt{3} }{2} ) = \frac{\pi }{3}

thus y = \frac{\pi }{3}

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?
8_murik_8 [283]

The inverse of the given function is y = √5x + 7/2 - 3

<h3>Inverse of a function</h3>

Given the function expressed below;

5y + 4 = (x+3)² +1/2

5y = (x+3)² - 7/2

y = 1/5(x+3)² - 7/10

Replace y as x

x = 1/5(y+3)² - 7/10

Make y the subject of the formula

5x = (y+3)²- 7/2

(y+3)² = 5x + 7/2

y+3 = √5x + 7/2

y = √5x + 7/2 - 3

Hence the inverse of the given function is y = √5x + 7/2 - 3
