Answer:
25/208 or 12.2%
Step-by-step explanation:
P(heart) = 13/52 = 1/4
P(red) = 26/52 = 1/2
because we are not replacing the first card drawn, the deck has 51 cards remaining
P(heart, red) = 1/4 × 25/52
= 25/208 or 12.2%

Cylinders A and B have the same radius but different heights. Which statement correctly compares cylinder A and cylinder B?
Answer:
The volume of cylinder B is 3 times the volume of Cylinder A
because the cylinder volume = pi r² h
h = hight
pi is a constant N
The volume of cylinder B is 3 times the Volume of cylinder A.
Option A is the correct answer.
What is a cylinder?
A cylinder is a three-dimensional figure that has a radius and a height.
The volume of a cylinder is πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume = 3.14 x 2 x 2 x 5 = 62.8 cubic cm
We have,
Cylinder A:
Radius = 6 cm
Height = 10 cm
Volume.
= π x 6² x 10
= 360π _____(1)
Cylinder B:
Radius = 6 cm
Height = 30 cm
Volume.
= π x 6² x 30
= 3 x 360π ______(2)
From (1) and (2) we get,
The volume of cylinder B = 3 x the Volume of cylinder A.
Thus,
The volume of cylinder B is 3 times the Volume of cylinder A.

Which of the following gives the area, A, of a circle with a diameter of 6? A A=π(3) B A=π×2(3) C A=π(3)2 D A=π×2(3)2
Answer:
C
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius )
here diameter = 6 , then r = 6 ÷ 2 = 3 , so
A = π(3)² → C

i don’t really know how to picture what the graph of the derivative would look like
Answer:
A) f'(3) < f'(0) < f'(-2)
Step-by-step explanation:
You don't need to create a graph of the derivative. Remember that the derivative is the slope/rate of change of a function at a certain point!
At f(-2), you can see that the function is increasing around it, which suggests that f'(-2) is positive.
At f(0), you can see that the function doesn't increase nor decrease around it, which suggests that f'(0) is 0 (or no slope!).
At f(3), you can see that the function is decreasing around it, which suggests that f'(3) is negative.
This must mean that f'(3) < f'(0) < f'(-2)

If [tex]\rm \dfrac{a}{d} = \dfrac{b}{e} = \dfrac{c}{f}[/tex] then lines have infinitely many solutions.
Which system of equations below has infinitely many solutions?y = –3x + 4 and 3y = –9x + 12
On comparing we have
a = -3 , b = 1, and c = 4
d = -9 , e = 3, and f = 12
Then their ratio will be
[tex]\rm \dfrac{1}{3} = \dfrac{-3}{-9} = \dfrac{4}{12}\\\\\rm \dfrac{1}{3} = \dfrac{1}{3} = \dfrac{1}{3}[/tex]
Hence y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.

Using what you know about angles and translations, find all of the angle
measures in the image below.
Answer:
∠1=135°
∠2=45°
∠3=45°
∠4=135°
∠5=135°
∠6=45°
∠7=45°
∠8=135°
Step-by-step explanation:
→∠1=∠4[Being vertically opposite angles]
→∠4=135°
→∠1=∠5[Corresponding angles]
→∠5=135°
→∠5=∠8[Being vertically opposite angles]
→∠8=135°
→∠1+∠2=180°[Sum of linear pair]
→∠2=180°-135°
→∠2=45°
→∠2=∠3[Being vertically opposite angles]
→∠3=45°
→∠3=∠6[Alternate angles]
→∠6=45°
→∠6=∠7[Being vertically opposite angles]
→∠7=45°
Answer:
∠1 = 135°
∠2 = 45°
∠3 = 45°
∠4 = 135°
∠5 = 135°
∠6 = 45°
∠7 = 45°
∠8 = 135°
Step-by-step explanation:
The diagram shows two lines that are intersected by a transversal. (A transversal is a line that passes through two lines in the same plane at two distinct points).When two lines are intersected by a transversal, the angles in matching corners are called Corresponding AnglesUsing the Angles on a Straight Line theorem
Angle 1 and 2 are on a straight line, so
∠2 = 180 - ∠1 = 180 - 135 = 45°
Similarly,
∠3 = 180 - ∠1 = 180 - 135 = 45°
∠4 = 180 - ∠3 = 180 - 45 = 135°
Using the Corresponding Angles theorem
As ∠1 = ∠5, then ∠5 = 135°
As ∠2 = ∠6, then ∠6 = 45°
As ∠3 = ∠7, then ∠7 = 45°
As ∠4 = ∠8, then ∠8 = 135°

1. We mentioned how the price of movie tickets has increased over time with inflation in Unit 6. Let’s let the equation y = 0.50(1.06)x represent the price of movie tickets for the years after 1950.
Using this equation, fill in the following T-table for the years 1950, 1960, 1970, 1980, and 1990. Use X = 0, 10, 20, 30, and 40 to represent these years (the number of years after 1950).
# years after 1950 X
Ticket Price $ Y
2. Answer these questions:
• Do these prices look reasonable?
• What is the y-intercept?
• Is this growth or decay?
3. Graph the points on the graph provided and draw a smooth curve to represent the graph of the equation.
4. Use the extended curve below to predict the ticket prices in the following years:
• 2000 (x = 50)
• 2010 (x = 60)
• Are these prices reasonable?
5. Answer these questions:
• What is the average price of a movie ticket where you live?
• What is the price of a matinee?
• Substitute the number of years after 1950 that it is right now into the equation y = 0.50(1.06)x. (For instance, if it is 2006, use x = 56.) What answer did you get?
• Why do you think this is the same or different from the first answer you gave in this question?
An exponential function is a function that has the form y = ab^x, where a represents the initial value, and b represents the rate
(1) How to fill the tableThe exponential function is given as:
[tex]y = 0.50(1.06)^x[/tex]
When x = 0, we have:
[tex]y = 0.50 * (1.06)^0 = 0.50[/tex]
When x = 10, we have:
[tex]y = 0.50 * (1.06)^{10} = 0.90[/tex]
When x = 20, 30 and 40 we have:
[tex]y = 0.50 * (1.06)^{20} = 1.60[/tex]
[tex]y = 0.50 * (1.06)^{30} = 2.87[/tex]
[tex]y = 0.50 * (1.06)^{40} = 5.14[/tex]
So, the complete table is:
Years after 1950 X : 0 | 10 | 20 | 30 | 40
Ticket Price $ Y : 0.50 | 0.90 | 1.60 | 2.87 | 5.14
(2) The y-intercept and the rateThe prices look reasonable.
The y-intercept is when x = 0.
So, the value of the y-intercept is 0.50
Also, the rate represents a growth.
This is so, because the rate is greater than 1
(3) The graphSee attachment for the graph of the exponential function
(4) The prices in 2000 and 2010When x = 50 and 60, we have:
[tex]y = 0.50 * (1.06)^{50} = 9.21[/tex]
[tex]y = 0.50 * (1.06)^60} = 16.49[/tex]
Hence, the prices in 2000 and 2010 are $9.21 and $16.49

y=2x y=7x + 15 substitution
Answer:
y = -6 and x = -3
Step-by-step explanation:
Data :
Eq 1 : y = 2x
Eq 2 : y = 7x + 15
So
Take eq 1 and solve for x
⇒ x = y/2 eq 3
Put eq 3 in eq 2
y =7 (y/2) + 15
y - 7y/2 = 15
( 2y-7y )/2 = 15
-5y/2 = 15
-5y =30
y = -6
And put value of y in eq 3 to find x
x = -6/2
x =-3
