cm
Solution
A=πr2=π·192≈1134.11495cm²
Answer: 1133.54
Step-by-step explanation:
The formula of area of a circle: A = [tex]\pi[/tex]r squared
All you have to do is plug the numbers in, so A= 3.14 (19) squared. Solve
19 times 19 = 361, and 3.14 times 361 = 1133.54
You draw one card from a standard deck of playing cards. If you pick a heart, you win $10. If you pick a face card, which is not a heart, you win $8. If you pick any other card you lose $6. What is the expected value of the game?
Answer:
The expected value of the game is $131
Step-by-step explanation:
54 Cards in a deck including Jokers
52 Cards in a deck not including Jokers
13 Hearts
13 Clubs
13 Spades
13 Diamonds
13 Face Cards
13 / 52 = 25% Chance Of Pulling A Heart
30 / 52 = 57% Chance Of Pulling A Face Card Not A Heart
9 / 52 = 17% Chance of Loosing $6
$130 = Pick A Heart
$81 = Face Card Not a Heart
$130+$81 = $211
30 x 6 = $180
The expected value of the game is $131

Which of the following are characteristics of the graph of the linear parent
function?
Check all that apply.
A. It is a straight line.
B. It is in quadrants II and IV.
C. It has a slope of 1.
D. It goes through the origin.
Answer: A,C, and D
Step-by-step explanation:
It is a straight line, it has a slope of 1 and it goes through the origin are the characteristics of the graph of the linear parent function
What is a function?A relation is a function if it has only One y-value for each x-value.
The linear parent function is the simplest form of a linear equation, which is y = x.
This equation has a slope of 1 and passes through the origin (0, 0).
The graph of y = x is a straight line that passes through the origin and extends infinitely in both directions.
Therefore, options A, C, and D are characteristics of the graph of the linear parent function.
Option B is not a characteristic of the linear parent function because it is not restricted to any specific quadrant; it passes through all four quadrants.
Hence, it is a straight line, it has a slope of 1 and it goes through the origin are the characteristics of the graph of the linear parent function

What is the slope, m, and the y-intercept of the line that is graphed below? On a coordinate plane, a line goes through points (negative 3, 0) and (0, 3). m = 1; (0, 3) m = 1; (–3, 0) m = –1; (0, 3) m = –1; (–3, 0)
Answer:
m = 1; (0, 3) is the correct answer.
Step-by-step explanation:
The general equation of a line is given by:
[tex]y=mx+c[/tex]
where, m is the slope of line
c is the y-intercept and
(x,y) are the points from where the line passes.
We are given that the line passes through 2 points (-3,0) and (0,3).
Putting the values of (x,y) in the equation of line.
Putting (0,3):
[tex]3 = m \times 0 + c\\\Rightarrow c =3[/tex]
So, y-intercept is (0,3).
Hence, equation of line becomes:
[tex]y = mx + 3[/tex]
Putting (-3,0) in [tex]y = mx + 3[/tex]:
[tex]0 = m(-3) +3\\\Rightarrow 3m = 3\\\Rightarrow m =1[/tex]
So, the equation of line becomes:
[tex]y = x +3[/tex]
Please find attached graph.
m = 1; y intercept (0, 3) is the correct answer.

–6
–4
4
6
Answer:
B -4
Step-by-step explanation:
-1.5(4 - r) = -12
Distribute -1.5.
-6 + 1.5r = -12
Add 6 to both sides.
1.5r = -6
Divide both sides by 1.5.
r = -4
Your answer is -4.
Answer:
r = -4
Step-by-step explanation:
-1.5(4-r)=-12
Divide each side by -1.5
-1.5 / -1.5 *(4-r)=-12 / -1.5
(4-r) =8
Subtract 4 from each side
4-r-4 = 8-4
-r = 4
Divide each side by -1
-r/-1 = 4/-1
r = -4

You need to create a fenced Off region of Land for cattle to graze. The grazing area must be a total of 500 square feet surrounded by a fence and in the shape of a regular polygon within this grazing area the length of the apothem must be 10 feet long.
Part. 1 find the total perimeter of the grazing area
Part 2. if the cost of the fence is $7.95 per linear foot how much will it cost to place a fence around the entire grazing area?
Part 3 - suppose this grazing area is 1/60 of an industrial grazing area for major industry farm. What is the total cost to build a fence around the entire land of the large scaled farm
Use property of proportions

Answer:
Part 1: The perimeter of total grazing area is 100 feet.
Part 2: The cost of fencing the entire grazing area is $759.
Part 3: The total cost to build a fence around the entire land of the large scaled farm is $ 45540.
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100

7 cm
7 cm
4.3 cm
The 6-sided shape is made from two of these rectangles.
Work out the perimeter of this 6-sided shap
Answer:36.6cm
Step-by-step explanation;
you can make a six sided shape by keeping the two rectangles as it makes the shape of L
perimeter = 2(4.3cm)+4(7cm)
=8.6cm=28cm
=36.6cm
The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
The perimeter of the circle = πd where d is the dia of the circle.
As per the drawn combined rectangle.
Perimeter = 2(4.3) + 4(7)
⇒ 36.6 cm
Hence "The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm".

I am a 2 dimensional shape that had 5 obtuse angles
Answer:
A pentagon.
Step-by-step explanation:
A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.
108° ≥ 90°, so the angles are obtuse.
Therefore, a 2-D shape with 5 obtuse angles is a pentagon.
The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.
Answer:
A = 236,000 (1+ 0.04)^9
335,902 people in 2009
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population (in 2000)
r = growing rate (decimal form) = 4/100 = 0.04
t= years
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04) ^t
To find the population in 2009:
We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)
Substituting t=9 in the function:
A = 236,000 (1+ 0.04)^9
A =335,902 people

The area of the circle is 9π m².
What is the area of the circle?
The area of a circle is the area inside the circle. Hence, the area of the circle = π × R².
Given, the diameter of the circle is(D) = 6 m.
Radius of the circle(R) = D/2 = 6/2 m = 3 m.
