Answer:

4 For Small

8 For big

Step-by-step explanation:

80 Square Inches in terms of pie, since one of the radius points are 2 times the other we can setup a equation

(Leaving out pi for simplicity)

R^2 + 2R^2= 80

Now since R is doubled in spot we can plug in points until we get the answer

1:2 (Too small)

2:4 (Too Small)

3:6 (Too small)

4:8 (Fits)

If we plug 4 for R it satisfies the equation for our criteria.

Answer:

A. 560

Step-by-step explanation:

multiply 600 by 0.93 in order to find out what 93% of 600 is.

600 x 0.93 = 558

since 558 isn't one of the options you find which one is closest to it, then divide by 600 in order to see if it's still 93%

a) 560/ 600 = 0.93333 = 93.3%

there's your answer.

but to compare it with the rest of the answer choices:

b) 540 / 600 = 0.9 = 90%

c) 470 / 600 = 0.78333 = 78.3%

d) 490 / 600 = 0.81667 = 81.6%

none of these are in the range of 93, so they're incorrect

Answer:

[tex]\tan (A+B) =-\frac{680}{111}[/tex]

Step-by-step explanation:

[tex]\tan A=\frac{12}{5}[/tex]

[tex]\cos B=\frac{45}{53}\implies \sec B=\frac{53}{45}[/tex]

Now, by trigonometric identity:

[tex]\tan^2 B =\sec^2B-1[/tex]

[tex]\implies \tan^2 B =\bigg(\frac{53}{45}\bigg)^2-1[/tex]

[tex]\implies \tan^2 B =\frac{(53)^2-(45)^2}{(45)^2}[/tex]

[tex]\implies \tan^2 B =\frac{(28)^2}{(45)^2}[/tex]

[tex]\implies \tan B =\pm\sqrt{\frac{(28)^2}{(45)^2}}[/tex]

[tex]\implies \tan B =\pm\frac{28}{45}[/tex]

It is given that: Angles A and B are in quadrant I.

---------------------> Angles A and B would be positive.

[tex]\implies \tan B =\frac{28}{45}[/tex]

Next,

[tex]\tan (A+B) =\frac{\tan A +\tan B}{1-\tan A \tan B}[/tex]

[tex]\implies \tan (A+B) =\frac{\frac{12}{5} +\frac{28}{45}}{1-\bigg(\frac{12}{5}\bigg) \bigg(\frac{28}{45}\bigg)}[/tex]

[tex]\implies \tan (A+B) =\frac{\frac{108}{45} +\frac{28}{45}}{1-\bigg(\frac{336}{225}\bigg)}[/tex]

[tex]\implies \tan (A+B) =\frac{\frac{136}{45}}{\bigg(\frac{225-336}{225}\bigg)}[/tex]

[tex]\implies \tan (A+B) =\frac{\frac{136}{45}}{\frac{-111}{225}}[/tex]

[tex]\implies \tan (A+B) =-\frac{680}{111}[/tex]

The rule for the transformation for the provided figure shown in the graph is f(x , y) = (y , x), as it is

Transformation of a figure is to change the size, shape or the position of a figure to create a new figure for required use.

The reflection of a plane or shape is flipping the original figure with respect to a reference line. The rule of reflection about x and y-axis is given below,

The given figure in the graph is reflected about y-axis. Thus, the rule for the transformation is,

[tex]f(x , y) = (-x , y)[/tex]

Hence, the rule for the transformation for the provided figure shown in the graph is f(x , y) = (y , x), as it is

The p-value is 0.622 for the sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings.

A hypothesis testing method is the Chi-square test. Two popular Chi-square tests involve comparing observed and expected frequencies in one or more categories.

The expected proportions are:

3/7, 3/7, 1/7 respectively

Test stasisttics = 0.978

Df = n -1 = 3 - 1 = 2

P-value = 0.622

Thus, the p-value is 0.622 for the sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings.

The number of days that had either rain or high winds for the considered case is 77

For two subsets A and B of the universal set U, we have:

[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)[/tex]

Assume that:

A and B be the subsets of what happens on each day.

Then in the days of last several weeks , we take:

then, as per the data given, we get:

Thus, we get:

[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)\\n(A \cup B) = 67 + 23 - 13 = 77[/tex]

Thus, n(A ∪B) = number of days seeing either rain or high winds = 77

Given x = acos³θ , y = asin³θ

Diffrentiating w.r.t. θ

dx/dθ = -3acos²θsinθ ____(1)

dy/dθ = 3asin²θcosθ ______(2)

diving (2) by (1)

dy/dθ ×dθ/dx = -( 3asin²θ cosθ /3acos²θsinθ )

dy/dx = - tanθ

dy/dx = slope of tangent = -tanθ

putting θ = π/4

∴ dy/dx =- tanπ/4 = -1

but , slope of normal = - 1/slope of tangent

∵ slope of normal = -1/-1 = 1

∴ slope of normal = 1 Answer

Answer:

Slope of normal = 1

Step-by-step explanation:

   [tex]\sf x =aCos^3 \ \theta\\\\\dfrac{dy}{d \theta} = a*3Cos^2 \ \theta (-Sin \ \theta)\\[/tex]

         [tex]\sf = -3aCos^2 \ \theta *Sin \ \theta[/tex]

[tex]\sf y =aSin^3 \ \theta\\\\\dfrac{dy}{d\theta}=a*3Sin^2 \ \theta*(Cos \ \theta)\\\dfrac{dy}{d\theta}=3aSin^2 \ \theta*Cos \ \theta[/tex]

          [tex]\sf Slope \ of \ Tangent = \dfrac{dy}{dx} =\dfrac{dy}{d\theta} \div \dfrac{dx}{d\theta}[/tex]

                    [tex]\sf = \dfrac{3aSin^2 \ \theta \ Cos \ \theta}{-3aCos^2 \ \theta \ Sin \ \theta}\\\\ = \dfrac{-Sin \ \theta}{Cos \ \theta}\\\\= -tan \ \theta[/tex]

[tex]\theta = \dfrac{\pi }{4}\\\\-tan\ \theta = -tan \ \dfrac{\pi }{4} \\\boxed{tan \ \dfrac{\pi }{4}=-1}[/tex]

Slope of tangent * slope of normal = -1

                                [tex]\boxed{\text{Slope of normal =$\dfrac{-1}{Slope \ of \ tangent}$}}[/tex]
