The sum of the areas of two circles is 80 square meters.find the length of a radius of each circle is one of them is twice as long as the other

Answers

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.

What is the transformation of figure?

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,

Reflection about x-axis     [tex](x,y)-- > (x,-y)[/tex]Reflection about y-axis      [tex](x,y)-- > (-x,y)[/tex]

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

What is the addition rule of size for two subsets?

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:

A = set of days which had rainB = set of days which had high winds,

then, as per the data given, we get:

n(A) = number of days seeing rain = 67n(B) = number of days seeing high winds = 23 n(A ∩B) = number of days seeing both rain and high winds = 13

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

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

Anastasia got 93% in her exam out of marks is 600 find out the obtained marks​
options: a) 560 b)540 c)470 d)490

Answers

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

Answers

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

How to determine the equation?

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

[tex]c = \frac{rt - 15}{t}[/tex]

Hence, the equation of c in terms of r and t is [tex]c = \frac{rt - 15}{t}[/tex]

Find the value of tan(A+B)

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]

f(x) = sinx - 3 cosx is a sinusoid.

True or false

Answers

It’s True because I did it for a quiz
Answer:  True

===========================================================

Explanation:

The function can be broken down into the form

f(x) = g(x) - 3*h(x)

where,

g(x) = sin(x)

h(x) = cos(x)

Both g and h are sinusoidal with the same period of 2pi. Therefore, the linear combination of these functions is also sinusoidal with the same period of 2pi. If the periods didn't match up, then it's likely the function isn't sinusoidal and instead some other complicated crazy curve.

Extra notes:

A sinusoidal curve is one that has a steady up and down smooth sine curve to it. Think of a simple ocean wave. A cosine curve is really a sine curve in disguise. It's been phase shifted 90 degrees or pi/2 radians. It's not a coincidence that the word "sine" is found in "cosine".When I say "period of 2pi", I mean the curve repeats itself every 2pi radians. This is equivalent to 360 degrees. The repeating pattern goes on forever.

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

dy/dx = - tanθ
