Answer:

so the closet value will be 21.

Step-by-step explanation:

In this question we have to calculate the value of 85% of 25.

To calculate the percentage first we have to write percentage to the fraction and then multiply with 25.

$\frac{85}{100}$ × 25

= 0.85 × 25

= 21.25

Therefore, the closet value of 21.25 will be 21 because when we round off, 0.25 will be waved off. Had this value been greater than 0.50 or equal to 0.5 than this value would have been 22.

so the closet value will be 21.

Answer:

Step-by-step explanation:

We are given that

85% of 25.

We have to find the value which is closest to 85% o 25.

To find the closes value we will convert percentage into fraction.

When we remove sign of percentage then we write 100 in denominator

85%= $\frac{85}{100}$

Now, 85% of 25= $\frac{85}{100}\times 25$

85% of 25= $\frac{85}{4}$

85% of 25= $21.25$

Therefore, the closes value of 85% of 25=21

Because tenth place 2 is less than 5 .Therefore, all digits on right side of tenth place digit replace by zero and digits on left side of tenth place remain same .

Hence, the closest value of 85% of 25=21

Alenkasestr [34]

Answer:

μ = Sin θ * d₁ / (d₂ - Cos θ*d₁)

d₂ = (d₁*Sin θ) / μ

Step-by-step explanation:

a) We apply The work-energy theorem

W = ΔE

W = - Ff*d

Ff = μ*N = μ*m*g

Distance 1:

- Ff*d₁ = Ef - Ei

⇒ - (μ*m*g*Cos θ)*d₁ = (Kf+Uf) - (Ki+Ui) = (Kf+0) - (0+Ui) = Kf - Ui

Kf = 0.5*m*vf² = 0.5*m*v²

Ui = m*g*h = m*g*d₁*Sin θ

then

- (μ*m*g*Cos θ)*d₁ = 0.5*m*v² - m*g*d₁*Sin θ

⇒ - μ*g*Cos θ*d₁ = 0.5*v² - g*d₁*Sin θ (I)

Distance 2:

- Ff*d₂ = Ef - Ei

⇒ - (μ*m*g)*d₂ = (0+0) - (Ki+0) = - Ki

Ki = 0.5*m*vi² = 0.5*m*v²

then

- (μ*m*g)*d₂ = - 0.5*m*v²

⇒ μ*g*d₂ = 0.5*v² (II)

If we apply (I) + (II)

- μ*g*Cos θ*d₁ = 0.5*v² - g*d₁*Sin θ

μ*g*d₂ = 0.5*v²

⇒ μ*g (d₂ - Cos θ*d₁) = v² - g*d₁*Sin θ (III)

Applying the equation (for the distance 1) we get v:

vf² = vi² + 2*a*d = 0² + 2*(g*Sin θ)*d₁ ⇒ vf² = 2*g*Sin θ*d₁ = v²

then (from the equation III) we get

μ*g (d₂ - Cos θ*d₁) = 2*g*Sin θ*d₁ - g*d₁*Sin θ

⇒ μ (d₂ - Cos θ*d₁) = Sin θ * d₁

⇒ μ = Sin θ * d₁ / (d₂ - Cos θ*d₁)

If μ is a known value

d₂ = ?

We apply The work-energy theorem again

W = ΔK ⇒ - Ff*d₂ = Kf - Ki

Ff = μ*m*g

Kf = 0

Ki = 0.5*m*v² = 0.5*m*2*g*Sin θ*d₁ = m*g*Sin θ*d₁

Finally

- μ*m*g*d₂ = 0 - m*g*Sin θ*d₁ ⇒ d₂ = Sin θ*d₁ / μ

Choose the function whose graph is given by:

katen-ka-za [31]

Answer:

D. $y=\tan (x-\pi)+2$

Step-by-step explanation:

We are given the graph of the transformed tangent function.

As, we can see that the graph is shifted 2 units upwards.

That is, the parent function is translated 2 units up.

So, the new function will be of the form, $y=\tan (x)+2$ .

Thus, options A and C are not correct.

Moreover, 'If a function f(x) has period P, then the function cf(bx) will have period $\frac{P}{|b|}$ .

Also, form the figure, we see that the period of the graphed function is $\pi$ .

Since, $y=\tan (x)$ have period $\pi$ .

So, function in option B will have period $\frac{\pi}{2}$ , which is not possible.

Further, function in option D have period $\pi$ .

Thus, the equation of the graphed function is, $y=\tan (x-\pi)+2$ .

How do u solve -18-6k=6 (1+3k)

Anarel [89]

Let's solve your equation step-by-step.−18−6k=6(1+3k)

Step 1: Simplify both sides of the equation.
−18−6k=6(1+3k)
Simplify: (Show steps)−6k−18=18k+6

Step 2: Subtract 18k from both sides.−6k−18−18k=18k+6−18k−24k−18=6

Step 3: Add 18 to both sides.−24k−18+18=6+18−24k=24

Step 4: Divide both sides by -24.−24k−24=24−24k=−1
