Step-by-step explanation:
A circle has a diameter of 3 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined.
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
The numerical value of the circumference is less than the numerical value of the area.
Using the area and the circumference of the circle, it is found that the correct statement is given by:
The numerical value of the circumference is greater than the numerical value of the area.
What is the area of a circle?The area of a circle of diameter d is given by:
[tex]A = \frac{\pi}{4}d^2[/tex]
What is the circumference of a circle?The circumference of a circle of diameter d is given by:
[tex]C = \pi d[/tex]
In this problem, we have that d = 3, hence:
[tex]A = \frac{\pi}{4} \times 3^2 = \frac{9\pi}{4} = 2.25\pi[/tex]
[tex]C = \pi \times 3 = 3\pi[/tex]
Hence the correct option is given by:
The numerical value of the circumference is greater than the numerical value of the area.

The change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.
What is linear function?Linear function is the function in which the highest power of the unknown variable is one. Linear functions used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
[tex]y=mx +c[/tex]
Here, (m) is the slope of the function and (c) is the y intercept.
The slope can be found out as,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The sound level is plotted on x-axis and frequency of people walking up (%) is plotted on y-axis. The slope of the line given the rate of change of y values with respect to x value.
In the graph given, the frequency of people walking up is 10 at 55 decibels and 55 at 95 decibels. The point, we get for this line are (55, 10) and (95, 55). Therefore the slope or the change of rate is,
[tex]\dfrac{dy}{dx}=\dfrac{55-10}{95-55}\\\dfrac{dy}{dx}=\dfrac{45}{40}\\\dfrac{dy}{dx}=\dfrac{9}{8}[/tex]
Hence, the change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.

At the city museum, child admission is $5.20 and adult admission is $9.50. On Friday,133 tickets were sold for a total sales of $928.10. How many adult tickets were sold that day?
Answers
Answer:
55 adult tickets were sold on Friday.
Step-by-step explanation:
A linear system will be used to model the system.
Let c be the number of child tickets and a be the number of adult tickets
Then according to given statements
[tex]a+c = 133\ \ \ \ Eqn\ 1\\9.50a+5.20c = 928.10\ \ \ Eqn\ 2[/tex]
From equation 1
[tex]a = 133-c[/tex]
Putting this in equation 2
[tex]9.50(133-c)+5.20c = 928.10\\1263.5-9.50c+5.20c=928.10\\1263.5-4.3c = 928.10\\-4.3c = 928.10-1263.5\\-4.3c=-335.4\\\frac{-4.3c}{-4.3} = \frac{-335.4}{-4.3}\\c = 78[/tex]
Putting c = 78 in equation 1
[tex]a+78 = 133\\a = 133-78\\a = 55[/tex]
Hence,
55 adult tickets were sold on Friday.

The area of the rectangle is 48 cm².
Show that x satisfies the equation x2+ 7x - 78=0
Answers
Answer:
area a=lxb
48=(x+10)x(x-3)
48=x2-3x+10x-30
0=x2+7x-30-48
0=x2+7x-78
hence it is proved
The requried, we have shown that x satisfies the equation x² + 7x - 78 = 0.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
The area of the rectangle is given by the formula:
Area = length x width
Substituting the given expressions for length and width, we have:
Area = (x + 10)(x - 3)
We are also told that the area of the rectangle is 48 cm², so we can set up the equation:
(x + 10)(x - 3) = 48
Expanding the left side using the FOIL method:
x² - 3x + 10x - 30 = 48
Simplifying:
x² + 7x - 78 = 0
Therefore, we have shown that x satisfies the equation x² + 7x - 78 = 0.

Step-by-step explanation:
To find:
The value of [tex]tan60^\circ[/tex] = ?
Solution:
Kindly consider the equilateral [tex]\triangle ABC[/tex] as attached in the answer area.
Let the side of triangle = [tex]a[/tex] units
Let us draw the perpendicular from vertex A to side BC.
It will divide the side BC in two equal parts.
i.e. BD = DC = [tex]\frac{a}{2}[/tex]
Using Pythagorean Theorem in [tex]\triangle ABD[/tex]:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]
Side AD = [tex]\frac{\sqrt3}{2}a[/tex]
Using Trigonometric ratio:
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tanB = \dfrac{AD}{BD}[/tex]
Putting the values of AD and BD:
[tex]tan60^\circ=\dfrac{\frac{\sqrt3}{2}a}{\frac{1}{2}a}\\\Rightarrow tan60^\circ = \bold{\sqrt3}[/tex]

y =2(x+3)
a) One
b) No solutions
c) Two solution
d) Infinitely Many solutions.
Answers
Answer:
b) No solutions
Step-by-step explanation:
y=2x+1
y= 2(x+3)
Substitute the y in y=2x+1 with 2(x+3)
2(x+3)=2x+1
Then distribute the 2.
2x+6=2x+1
Subtract 2x from both sides to isolate the variable.
6=1

Original equation:
7/2x - 3(5x - 1/2) = ?
Use distributive property for the parentheses
-3 · 5x = -15x
-3 · (-1/2) = 3/2 or 1.5
Plug these values into the equation
7/2x - 15x + 1.5 = ?
Combine like factors
-11.5x + 1.5 = a (a = answer)
The equation with fractions:
-11 1/2 + 1 1/2 = a

Let : A = ( - 2 , - 6 ) & B = ( 3 , 9 )
[tex]d = distance \: \: between \: \: points \\ [/tex]
[tex]d = \sqrt{ ( \: {y(B) - y(A) } \: )^{2} + ( \: { x(B) - x(A) } \: )^{2} } \\ [/tex]
[tex]d = \sqrt{ ( \: {9 - ( - 6)} \: )^{2} + ( \: {3 - ( - 2)} \: )^{2} } \\ [/tex]
[tex]d = \sqrt{ ( \: {9 + 6} \: )^{2} + ( \: {3 + 2} \: )^{2} } \\ [/tex]
[tex]d = \sqrt{ {15}^{2} + {5}^{2} } [/tex]
[tex]d = \sqrt{225 + 25} [/tex]
[tex]d = \sqrt{250} [/tex]
[tex]d = \sqrt{25 \times 10} [/tex]
[tex]d = \sqrt{ {5}^{2} \times 10 } [/tex]
