Answer:
[tex]8.86cm^2[/tex]
Step-by-step explanation:
Given the rectangle of 3cm by 4cm and a circle of 1 cm inside it:
The Area of the shaded portion =Area of Rectangle-Area of Circle
Area of a Rectangle=Length X Width[tex]=3 X 4 =12cm^2[/tex]
Area of the circle =[tex]\pi r^2=\pi X 1^1=3.142cm^2[/tex]
Area of the shaded portion=12-3.142
[tex]=8.86cm^2[/tex]
The area of the shaded region inside the rectangle but outside the circle is 8.86 cm².
Explanation:A circle with a radius of 1 cm sits inside a rectangle with dimensions of 3 cm by 4 cm. To solve this problem, we can use the formula to find the area of a rectangle and the area of a circle.
The area of the rectangle is calculated by multiplying its length by its width, giving us an area of 12 cm². The area of the circle can be found using the formula A = πr², where A represents the area and r represents the radius.
Plugging in the given radius of 1 cm, we find that the area of the circle is π cm², which is approximately 3.14 cm². Therefore, the area of the shaded region (the region inside the rectangle but outside the circle) is 12 cm² - 3.14 cm² = 8.86 cm².

What is the value of y? NU=9, NM= 3, MT= 6, TN= y
Answer:
6[tex]\sqrt{3}[/tex]
Step-by-step explanation:
We have to use Pythagoras' identity twice to find y
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
In right triangle MUT to find TU
TU² + 3² = 6², that is
TU² + 9 = 36 ( subtract 9 from both sides )
TU = 27 ( take the square root of both sides )
TU = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = 3[tex]\sqrt{3}[/tex]
In right triangle NUT to find y

Explain how you find m∠3 if m∠5 = 130° and m∠4 = 70°. *
Answer:
The required measure of angle 3 is 60°.
Step-by-step explanation:
We are given to find the measure of angle 3 from the figure if
m∠5 = 130° and m∠4 = 70°.
Let the measure of angle 3 be x°.
From the figure, we note that
angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.
We know that
the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.
So, we get
Thus, the required measure of angle 3 is 60°.

Factor completely.
5x 2 + 10x - 40
Answer:
(x + 4)(x - 2)
Step-by-step explanation:
For factoring when there's a coefficient on the leading variable, I use the "slip n' slide" method (my teacher called it that, I had no part in naming it), but when that fails, you can use the quadratic formula.
First, you "slip" the leading coefficient to the end, and multiply.
5x² + 10x - 40
x² + 10x - 200
Now, you factor it normally.
x² + 10x - 200
= (x + 20)(x - 10)
Then, you divide the 2nd part in each parentheses with the coefficient you slipped in the beginning. This is super important! I always had trouble remembering this step, so hopefully you won't.
(x + 20/5)(x - 10/5)
= (x + 4)(x - 2)

Jesse played two days of golf. On the second day, he got a score of 6 below par, or −6. His total score for the two days was 0 above par, or 0. Define a variable. Then write and solve an equation to find the score Jesse got on the first day. Show your work.
Answer:
6
Step-by-step explanation:
The total of the two days adds up to 0. So define x as the score of the first day, and then have the equation x - 6 = 0.
Then solve,
x - 6 (+6) = 0 (+6)
x + 0 = 6
x = 6

Which function below will translate f(x) = x2 left 5 units and down 1 unit?
Answer:
its c. trust me
Step-by-step explanation:
The resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.
What is transformation of a function?Transformation of a function is shifting the function from its original place in the graph.
Types of transformation-
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.The given function is,
[tex]f(x) = x^2[/tex]
It has to be translated left 5 units. For this we have to add 5 units in the above function. Thus the function become,
[tex]f(x) = (x+5)^2[/tex]
Now the function is translated down 1 unit. For this we have to substract 1 units outside of the above function. Thus the function become,
[tex]f(x) = (x+5)^2-1[/tex]
Hence, the resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.

The newest iPad costs $850 and has a sales tax of 11%. What will be the total cost?
Answer:
$943.5
Step-by-step explanation:
Tax: 11% of 850
11/100 × 850 = 93.5
Total cost = 850 +93.5
= 943.5
A total is $943.50.
To calculate the total cost of the newest iPad including the sales tax, we need to add the tax to the initial price of the product. The iPad costs $850, and the sales tax rate is 11%. To find the tax amount, convert the percentage to a decimal by dividing by 100, which gives us 0.11, and then multiply this by the cost of the iPad.
Sales Tax = iPad Cost x Tax Rate
Sales Tax = $850 x 0.11
Sales Tax = $93.50
Now, to find the total cost, add the initial iPad cost to the sales tax:
Total Cost = iPad Cost + Sales Tax
Total Cost = $850 + $93.50
Total Cost = $943.50

Which of the following is true of functions and their inverses?
The inverse of a quadratic function is not a function.
The inverse of a quadratic function is always a function.
The inverse of a linear function is not a function.
The inverse of a linear function is always a function.
The inverse of a quadratic function is not always a function, as it can assign multiple outputs to a single input. Conversely, the inverse of a linear function is always a function because it strictly assigns one output to each input.
Explanation:The presented statements about the nature of functions and their inverses are particularly related to the definition of a function. A function is a rule which assigns to each input exactly one output. Considering this, the inverse of a quadratic function is not always a function because it can assign multiple outputs (y-values) to a single input (x-value). This is why the graph of a quadratic function doesn't pass the 'horizontal line test', which is a criterion for a graph to represent a function.
On the other hand, the inverse of a linear function is indeed always a function. Because a linear function always assigns exactly one output to each input, its inverse will also satisfy the definition of a function.

The area of the lily pad is about [ ] ft^2.
(options for both: 14.1, 63.6, 254.3, 28.3)
Answer:
Circumference of the lily pad is about 28.3 ft
Area of the lily pad is about 63.6 ft²
Step-by-step explanation:
Formula for circumference of circle is,
Circumference = 2 π r
Given that diameter is 9 ft. Therefore radius is half of diameter.
[tex]r=\dfrac{d}{2}[/tex]
Substituting the values,
[tex]r=\dfrac{9}{2}=4.5[/tex]
Also value of π = 3.14
Substituting the value,
C = 2 × 3.14 × 4.5
Simplifying,
C = 28.26 ft
Rounding to nearest tenth value of circumference is C = 28.3 ft.
Formula for area of circle is,
A = π r²

A company’s mean salary is $65,000 with a standard deviation of $6,000. What is the probability that an employee makes between $70,000 and $80,000?
Answer:
0.19706
Step-by-step explanation:
-Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
[tex]P(70000<X<80000)=P(\frac{X_1-\mu}{\sigma}<z<\frac{X_2-\mu})\\\\=P(\frac{70000-65000}{6000}<z<\frac{80000-65000}{6000})\\\\=P(0.8333<z<2.5)\\\\\\=0.99379-0.79673\\\\=0.19706[/tex]
Hence,the probability that an employee makes between $70,000 and $80,000 is 0.19706
Final answer:
To find the probability that an employee makes between $70,000 and $80,000, we calculate the z-scores and use the z-table. The probability is 0.1971.
Explanation:
To find the probability that an employee makes between $70,000 and $80,000, we need to calculate the z-scores and use the z-table.
First, we calculate the z-score for $70,000:
z = (X - μ) / σ
z = (70000 - 65000) / 6000 = 0.8333
Next, we calculate the z-score for $80,000:
z = (80000 - 65000) / 6000 = 2.5
Using the z-table, we can find the probabilities associated with these z-scores. The probability of an employee making less than $70,000 is 0.7967, and the probability of an employee making less than $80,000 is 0.9938. Therefore, the probability of an employee making between $70,000 and $80,000 is:
P(70000 < X < 80000) = P(X < 80000) - P(X < 70000) = 0.9938 - 0.7967 = 0.1971
