Lilit [14]3 years ago
4 0

Answer:

9y + 5x

Step-by-step explanation:

Combine like terms. Like terms are terms with the same amount of variables. Reorder the terms:

5y + 2y + 2y + 6x - x

Combine like terms:

(5y + 2y + 2y) + (6x - x)

(9y) + (5x)

9y + 5x is your answer.

Lucia wishes to advertise her business, so she gives packs of 6 red flyers to each restaurant owner and sets of 4 blue flyers to
mylen [45]

Answer:

12

Step-by-step explanation:

No. of red flyers = 6

No. of blue flyers = 4

We need to find the minimum number of flyers of each color if she gave out the same number of red and blue flyers. For this we must find the LCM of 6 and 4.

Prime factorization of 6 = 2×3

Prime factorization of 4 = 2×2

Lowest common multiple of 6 and 4 = 12

Hence, there are 12 minimum number of flyers of each color

What is the exponential form for 7^√x^3
Semenov [28]

Answer:

The exponential form of this would be (7x)^3/2

Step-by-step explanation:

The square root symbol is the same as writing raised to the 1/2. So we can rewrite the equation as:

[(7x)^1/2]^3

Then we can multiply the two exponents in this case giving us

(7x)^3/2

The range of a projectile that is launched with an initial velocity v at an angle of a with the horizontal is given by R
lara31 [8.8K]

Answer:

\theta=30.285^{\circ}

Step-by-step explanation:

The range of a projectile is given by :

R=\dfrac{u^2\sin2\theta}{g}

Put R = 20 m, u = 15 m/s and finding the value of angle of projection

So,

R=\dfrac{u^2\sin2\theta}{g}\\\\\sin2\theta=\dfrac{Rg}{u^2}\\\\\sin2\theta=\dfrac{20\times 9.8}{15^2}\\\\\sin2\theta=0.871\\\\2\theta=\sin^{-1}(0.871)\\\\2\theta=60.57\\\\\theta=30.285^{\circ}

So, the required angle of projection is equal to 30.285^{\circ}.
