The distance the water sprays as the sprinkler rotates is 7.34 ft

Since the grassy area is circular, its area is the area of a circle.

So, A = πr² where r = radius of circle = distance sprinkler sprays

Making r subject of the formula, we have

r = √(A/π)

Since A = 172 ft², substituting the values of the variables into the equation, we have

r = √(A/π)

r = √(172 ft²/π)

r = √(172 ft²/3.142)

r = √(54.749 ft²)

r = 7.34 ft

So, the distance the water sprays as the sprinkler rotates is 7.34 ft

Answer:

1.404

Step-by-step explanation:

Given:

[tex]\log_43 \approx 0.792[/tex]

[tex]\log_421 \approx 2.196[/tex]

[tex]\log_421 =\log_4(3 \times 7)=\log_43+\log_47[/tex]

[tex]\implies 2.196\approx 0.792+\log_47[/tex]

[tex]\implies \log_47 \approx 2.196-0.792[/tex]

[tex]\implies \log_47 \approx 1.404[/tex]

Step-by-step explanation:

We know that the function period is 3 so the b value is

[tex] \frac{2\pi}{b} = 3[/tex]

[tex]b = \frac{2\pi}{3} [/tex]

So our b is 2 pi/3.

The midline is -3 and the amplitude is 2.Since this function isn't symmetric about y axis, and looks symmetric about orgin, we trig function will be Sine so we have

[tex]2 \sin ( \frac{2\pi}{3}x ) - 3[/tex]

The function passes through 0,-3 and our function on the graph passes through 1,-3 so we shift one unit to left.

[tex]2 \sin(\frac{2\pi}{3}(x + 1) ) - 3[/tex]

As we know that the standard equation of circle is [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex] , where r is the radius of circle and centre at (h,k)

Now , as the circle passes through (2,9) so it must satisfy the above equation after putting the values of h and k respectively

[tex]{:\implies \quad \sf \{2-(-1)\}^{2}+(9-5)^{2}=r^{2}}[/tex]

[tex]{:\implies \quad \sf (3)^{2}+(4)^{2}=r^{2}}[/tex]

[tex]{:\implies \quad \sf 9+16=r^{2}}[/tex]

After raising ½ power to both sides , we will get r = +5 , -5 , but as radius can never be -ve . So r = +5

Now , putting values in our standard equation ;

[tex]{:\implies \quad \sf \{x-(-1)\}^{2}+(y-5)^{2}=(5)^{2}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(x+1)^{2}+(y-5)^{2}=25}}}[/tex]

This is the required equation of Circle

Answer:

x = 21

Step-by-step explanation:

Angle 1 and angle 2 are supplementary because they make a straight line

so their sum is equal to 180:

m<1 + m<2 = 180

x + 96 + 3x = 180 add like terms

4x + 96 = 180 subtract 96 from both sides

4x = 84 divide both sides by 4

x = 21 to fins the angle measure replace x with the value we found

Answer:

Second answer

Step-by-step explanation:

We are given [tex]\displaystyle \large{\sec \theta = -3}[/tex] and [tex]\displaystyle \large{\sin \theta > 0}[/tex]. What we have to find are [tex]\displaystyle \large{\cot \theta}[/tex] and [tex]\displaystyle \large{\cos \theta}[/tex].

First, convert [tex]\displaystyle \large{\sec \theta}[/tex] to [tex]\displaystyle \large{\frac{1}{\cos \theta}}[/tex] via trigonometric identity. That gives us a new equation in form of [tex]\displaystyle \large{\cos \theta}[/tex]:

[tex]\displaystyle \large{\frac{1}{\cos \theta} = -3}[/tex]

Multiply [tex]\displaystyle \large{\cos \theta}[/tex] both sides to get rid of the denominator.

[tex]\displaystyle \large{\frac{1}{\cos \theta} \cdot \cos \theta = -3 \cos \theta}\\\displaystyle \large{1=-3 \cos \theta}[/tex]

Then divide both sides by -3 to get [tex]\displaystyle \large{\cos \theta}[/tex].

Hence, [tex]\displaystyle \large{\boxed{\cos \theta = - \frac{1}{3}}}[/tex]

__________________________________________________________

Next, to find [tex]\displaystyle \large{\cot \theta}[/tex], convert it to [tex]\displaystyle \large{\frac{1}{\tan \theta}}[/tex] via trigonometric identity. Then we have to convert [tex]\displaystyle \large{\tan \theta}[/tex] to [tex]\displaystyle \large{\frac{\sin \theta}{\cos \theta}}[/tex] via another trigonometric identity. That gives us:

[tex]\displaystyle \large{\frac{1}{\frac{\sin \theta}{\cos \theta}}}\\\displaystyle \large{\frac{\cos \theta}{\sin \theta}[/tex]

It seems that we do not know what [tex]\displaystyle \large{\sin \theta}[/tex] is but we can find it by using the identity [tex]\displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta}}[/tex]  for [tex]\displaystyle \large{\sin \theta > 0}[/tex].

From [tex]\displaystyle \large{\cos \theta = -\frac{1}{3}}[/tex] then [tex]\displaystyle \large{\cos ^2 \theta = \frac{1}{9}}[/tex].

Therefore:

[tex]\displaystyle \large{\sin \theta=\sqrt{1-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{9}{9}-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{8}{9}}}[/tex]

Then use the surd property to evaluate the square root.

Hence, [tex]\displaystyle \large{\boxed{\sin \theta=\frac{2\sqrt{2}}{3}}}[/tex]

Now that we know what [tex]\displaystyle \large{\sin \theta}[/tex] is. We can evaluate [tex]\displaystyle \large{\frac{\cos \theta}{\sin \theta}}[/tex] which is another form or identity of [tex]\displaystyle \large{\cot \theta}[/tex].

From the boxed values of [tex]\displaystyle \large{\cos \theta}[/tex] and [tex]\displaystyle \large{\sin \theta}[/tex]:-

[tex]\displaystyle \large{\cot \theta = \frac{\cos \theta}{\sin \theta}}\\\displaystyle \large{\cot \theta = \frac{-\frac{1}{3}}{\frac{2\sqrt{2}}{3}}}\\\displaystyle \large{\cot \theta=-\frac{1}{3} \cdot \frac{3}{2\sqrt{2}}}\\\displaystyle \large{\cot \theta=-\frac{1}{2\sqrt{2}}[/tex]

Then rationalize the value by multiplying both numerator and denominator with the denominator.

[tex]\displaystyle \large{\cot \theta = -\frac{1 \cdot 2\sqrt{2}}{2\sqrt{2} \cdot 2\sqrt{2}}}\\\displaystyle \large{\cot \theta = -\frac{2\sqrt{2}}{8}}\\\displaystyle \large{\cot \theta = -\frac{\sqrt{2}}{4}}[/tex]

Hence, [tex]\displaystyle \large{\boxed{\cot \theta = -\frac{\sqrt{2}}{4}}}[/tex]

Therefore, the second choice is the answer.

__________________________________________________________

Summary

[tex]\displaystyle \large{\sec \theta = \frac{1}{\cos \theta}}\\ \displaystyle \large{\cot \theta = \frac{1}{\tan \theta} = \frac{\cos \theta}{\sin \theta}}\\ \displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta} \ \ \ (\sin \theta > 0)}\\ \displaystyle \large{\tan \theta = \frac{\sin \theta}{\cos \theta}}[/tex]

[tex]\displaystyle \large{\sqrt{\frac{x}{y}} = \frac{\sqrt{x}}{\sqrt{y}}}[/tex]
