Which expression is equivalent to RootIndex 3 StartRoot x Superscript 5 Baseline y EndRoot?

IRINA_888 [86]

Answer:

The answer is " $x^{\frac{5}{3}}y^{\frac{1}{3}}$ "

Step-by-step explanation:

Given value:

$\to \bold{ \sqrt[3]{x^5y} }$

$\to \sqrt[3]{x^5y} =(x^5y)^{\frac{1}{3}}$

formula:

$\bold{(a.b)^n=a^nb^n}$

$\to (x^5y)^{\frac{1}{3}}= x^{\frac{5}{3}}y^{\frac{1}{3}}$

The final value is: $\boxed{\boxed{ x^{\frac{5}{3}} \cdot y^{\frac{1}{3}}}}$

Leena loves peanut butter. today, she ate four tablespoons of it. if there are 6 mg of vitamin e in four tablespoons of peanut b

velikii [3]

<span>First, we need to know that the current recommended daily allowance of Vitamin E is 15 milligrams. If Leena ate four tablespoons of peanut butter, thus receiving only 6 milligrams, then we can determine the percentage by first dividing 100 into 15 parts (which gives us 6.66), and then multiply that answer by 6 (6 x 6.66), which gives us precisely 40. Thus, the answer is 40 percent.</span>

What is the value of m,the points (2,3),(3,6)and (m,12) are collinear....Please y'all help me out

timurjin [86]

Answer:

m = 5

Step-by-step explanation:

Since the points are collinear, they all lie on the same line and have the same slope between them.

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (3, 6)

m = $\frac{6-3}{3-2}$ = $\frac{3}{1}$ = 3

Now calculate the slope using 2 other points and equate to 3

(x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (m, 12)

m = $\frac{12-6}{m-3}$ = $\frac{6}{m-3}$ = 3 ( multiply both sides by m - 3 )

6 = 3(m - 3) ← divide both sides by 3

2 = m - 3 ( add 3 to both sides )

5 = m

slamgirl [31]

The given question have mistake. The correct question is written below.

Question:

A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?

Answer:

Option B:

$h(t)=-4.9 t^{2}+6.37t$

Solution:

<u>General formula for the height of the projectile over time:</u>

(1) $h(t)=-16 t^{2}+v t+s$

Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)

(2) $h(t)=-4.9 t^{2}+v t+s$

Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)

Given initial velocity = 6.37 s and initial height is 0.

The height of the dog is in meters.

So, use second formula and substitute v = 6.37 and s = 0.

$h(t)=-4.9 t^{2}+v t+s$

$h(t)=-4.9 t^{2}+6.37t+0$

$h(t)=-4.9 t^{2}+6.37t$

Hence option B is the correct answer.
