<u>Answer:</u>

$x = \bf -7$

<u>Step-by-step explanation:</u>

$\frac{3}{4} (x + 21) = 10\frac{1}{2}$

• Divide both sides by $\frac{3}{4}$ :

⇒ $x + 21 = 10\frac{1}{2} \space\ \div \frac{3}{4}$

⇒ $x + 21 = 10\frac{1}{2} \space\ \times \frac{4}{3}$

⇒ $x + 21 = 14$

• Subtract 21 from both sides:

⇒ $x = 14 -21$

⇒ $\boxed {x = \bf -7}$

3/4(x+21) = 10.5
0.75x+15.75 = 10.5
0.75x = -5.25
x = -7

Hope it helps : )

For the equation ae^ct=d, solve for the variable t in terms of a,c, and d. Express your answer in terms of the natural logarithm

saveliy_v [14]

We have been given an equation $ae^{ct}=d$ . We are asked to solve the equation for t.

First of all, we will divide both sides of equation by a.

$\frac{ae^{ct}}{a}=\frac{d}{a}$

$e^{ct}=\frac{d}{a}$

Now we will take natural log on both sides.

$\text{ln}(e^{ct})=\text{ln}(\frac{d}{a})$

Using natural log property $\text{ln}(a^b)=b\cdot \text{ln}(a)$ , we will get:

$ct\cdot \text{ln}(e)=\text{ln}(\frac{d}{a})$

We know that $\text{ln}(e)=1$ , so we will get:

$ct\cdot 1=\text{ln}(\frac{d}{a})$

$ct=\text{ln}(\frac{d}{a})$

Now we will divide both sides by c as:

$\frac{ct}{c}=\frac{\text{ln}(\frac{d}{a})}{c}$

$t=\frac{\text{ln}(\frac{d}{a})}{c}$

Therefore, our solution would be $t=\frac{\text{ln}(\frac{d}{a})}{c}$ .

- If the contact time between bat and ball is 3.00 10-3 s, calculate the average force between the ball and bat during contact. ... now that we have dp we divide it by 3 x 10^-3 s. ... therefore the average force ( or impulse) between the ball and the bat during contact is 12000 N.

Problem 5. A skating rink in the shape shown has an area of

nexus9112 [7]

Answer:

$P=\dfrac{\pi r^2+2800}{r} $ ft$

Step-by-step explanation:

Let the length of the rectangular part =l

The width will be equal to the diameter of the semicircles.

Area of the Skating Rink= $2(\frac{\pi r^2}{2})+(lX2r)$

Therefore:

$\pi r^2+2lr=2800\\2lr=2800-\pi r^2\\$Divide both sides by 2r\\l=\dfrac{2800-\pi r^2}{2r}$

Perimeter of the Shape =Perimeter of two Semicircles + 2l

$=2\pi r+2\left(\dfrac{2800-\pi r^2}{2r}\right)\\=2\pi r+\dfrac{2800-\pi r^2}{r}\\=\dfrac{2\pi r^2+2800-\pi r^2}{r}\\=\dfrac{\pi r^2+2800}{r}$

The perimeter of the rink is given as:

$P=\dfrac{\pi r^2+2800}{r} $ ft$
