A basketball has the radius of 13 inches
What is the volume?

Step-by-step explanation:

Riders must be at least 48 inches. "At least" means greater than or equal to. Therefore, the inequality is:

h ≥ 48

To graph this, we draw a solid dot at the 48 mark (because it can equal 48) and an arrow to the right (because it can be greater than 48).

Answer:

The required value of y for the given inverse relation is 30.78

What is the inverse variation?

Inverse variation occurs when one variable varies inversely with respect to another. It represents the inverse relationship between two quantities are two quantities.

In mathematics, inverse variation refers to the relationships between variables that are expressed as y = k/x, where x and y are two variables and k is a constant value. It states that if the value of one quantity rises, the value of the other quantity falls.

Given, y varies inversely as [tex]x^{2}[/tex]

That is, y∝ 1/ [tex]x^{2}[/tex]

or, y = k/ [tex]x^{2}[/tex]

or,  [tex]x^{2}[/tex]y = k

And, y=38 when x=18

Then,  [tex]18^{2}[/tex]*38 = k

k = 12312

Now, if x=20 then y=?

[tex]x^{2}[/tex]y = 12312

or,  [tex]20^{2}[/tex]*y = 12312

or, 400y = 12312

or, y = 12312/400 = 30.78

Hence, the required value of y is 30.78

Answer: 64

Step-by-step explanation:

43 = (4)(4)(4)

=64

OR

4x4x4=64

The value of x has been solved as 6.4

We would have EG = EF + FG

where EG = 70

EF = 4x-3

FG =  6x+9

We would have to put these values in the equation that we have above, such that we would have, To the respective variables, connect the related terms:

70 = (4x-3) + (6x+9)

Separate the x variable. Because of the equal symbol, everything you do on one side also affects the other.

Open the brackets

70 = 4x + 6x -3 + 9

70 = 10x + 6

70 - 6 = 10x

64 = 10x

divide through by 10

x = 64 / 10

x = 6.4

Hence the value of x would be given as 6.4

After solving, the maximum height of the ball is 90.25 feet.

In the given question,

A person standing close to the edge on top of a 48-foot building throws a ball vertically upward.

The quadratic function

h(t) = -16t^2+52t + 48 models the ball's height about the ground, h(t) in feet, t seconds after it was thrown.

We have to find the maximum height of the ball.

Height is given that;

h(t) = -16t^2+52t + 48

Now comparing the given equation by the standard equation ax^2+bx+c=0

Here b = 52, a = -16

For maximum height put t= -b/2a

t = -52/2(-16)

t = 52/32

t = 1.625

Maximum height

h(1.625) = -16(1.625)^2+52(1.625) + 48

h(1.625) = -42.25+ 84.5 + 48

h(1.625) = 90.25 feet

The maximum height of the ball is 90.25 feet.

Step-by-step explanation:

To find the arc length of the polar curve r = 8cosθ between 0 and π/4, we can use the formula for arc length:

L = ∫a^b √(r^2 + (dr/dθ)^2) dθ

Substituting in the values for r and dθ, we get:

L = ∫0^(π/4) √(8^2cos^2θ + (-8sinθ)^2) dθ

= ∫0^(π/4) √(64cos^2θ + 64sin^2θ) dθ

= ∫0^(π/4) √(64) dθ

= ∫0^(π/4) 8 dθ

= 8(π/4 - 0)

= 8π/4

= 2π

Therefore, the arc length of the polar curve r = 8cosθ between 0 and π/4 is 2π.

The probability that the blood pressure of woman is more than 130 by given normal distribution is 0.9505

What is z-value?

The standard score in statistics is the amount of standard deviations that a raw score deviates from or exceeds the mean of the phenomenon being observed or assessed. Standard scores are positive for raw scores above the mean.

We are given a normal distribution with a mean value 115 and standard deviation 9

And we are asked to find the probability that a woman selected at random has blood pressure greater than 130

We first find the z-value

z= (x-μ)/σ

z= (130-115)/9

z= 15/9

z= 1.6666

Answer:

Step-by-step explanation: h(t)=-16t2+85

Let h(t)=0 to find when the object will hit the ground

0=-16t2+85

Solve for t=?

We need to get t term on its own

Take 85 from both sides

0-85=-16t2+85-85

-85=-16t2

To get t term on its own

Divide both sides by -16

-85/-16=-16t2/-16

5.3=t2

We have to solve for t squared that means we must take the square root of both sides

the square root of 5.3=gives + or - 2.3 seconds we can't have negative time so discard -2.3 seconds

Step-by-step explanation:

The antenna's height is determined to be 10 m using right triangle relations.

Following are the relationships in a right triangle:

The sine of an angle is equal to the length of the hypotenuse divided by the length of the side opposite the angle.

The cosine of an angle is equal to the neighboring side's length divided by the hypotenuse's length.

The tangent of an angle is calculated by dividing the length of the angle's adjacent side by its opposite side.

So, n this case, the side opposite to the 17o angle is the vertical height from her eyes to the top of the antenna, and the next side is the horizontal distance of 29 m, then:

tan 17° = h/29

h = 29 tan 17°

h = 8.87

Including eye height:

h = 8.87 + 1.51 = 10.38 m.

The antenna is 10 meters tall, rounded to the nearest meter.

Therefore, the antenna's height is determined to be 10 m using right triangle relations.

Part of your job as manager is to count the cash for the daily bank deposit. When you count the cash, you have 47 ones, 22 fives, 9 tens and 17 twenties. You also have 67 pennies, 12 nickels, 9dimes and 15 quarters. What is the total amount of the deposit?

47 ones = $47

22 fives = $110

9 tens = $90

17 twenties = $340

67 pennies = $0.67

12 nickels = $ 0.60

9 dimes = $0.90

15 quarters = $3.75

$47 + $110 + $90 + $340 + $0.67 + $ 0.60 + $0.90 + $3.75 = $592.92

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that A survey of 2000 subscribers to a certain news paper revealed that 1800  people subscribe to the daily morning edition  

And 1000 subscribe to both the daily and the sunday editions.  

Let x denote the number who subscribe to the Sunday edition.  

Then the addition rule with overlap tells us that is;

1800 + x – 1000 = 2000

800 + x = 2000  

x = 1200

Step-by-step explanation:

The number of apples x will be 10 and the number of bananas y will be 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Ethan and his children went into a grocery store and he bought $6 worth of apples and bananas. Each apple costs $0.75 and each banana costs $0.30. He bought a total of 14 apples and bananas altogether.

The number of apples and bananas will be calculated as,

0.75x +0.30y = 6

x + y = 14 or x = 14 - y

0.75(14-y) = 0.30y = 6

10.5-0.75y + 0.30y = 6

y = 10

x = 14  - y

x = 14 - 10 = 4

Therefore, the number of apples x will be 10 and the number of bananas y will be 4.

Answer:

  x² +8x -15 = 0

Step-by-step explanation:

You want a quadratic such that the sum of the roots is -8 and their product is -15.

When the roots of a quadratic are p and q, its factored form is ...

  (x -p)(x -q) = 0

The expanded form of this is ...

  x² -(p+q)x +pq = 0

That is, the coefficient of x is the opposite of the sum of the roots, and the constant is the product of the roots.

Here, we want the sum of roots to be -8, so the x-coefficient will be the opposite of that: 8. The constant will be the product of the roots: -15. That makes the desired quadratic be ...

  x² +8x -15 = 0

Each person will have 3 quects when they have the same amount

Given that:

Andrea started out the day with 2 quects and sold some each hour. Lee started the day with 12 quects and sold some each hour.

The equation of a line is of the form y = mx+c

where m is the slope and c is the y-intercept

For Lee

y =mx+c

c = 12

m = 12-8/0-1 = 4/( -1) = -4

y = -4x+12

For Andrea

y =mx+c

c = 2

m = 2-1/0-1.5 = 1/(-1.5) = -2/3

y = -2/3 x + 2

At the same amount y = -4x+12 is equal to y = -2/3 x + 2. Thus:

-4x+12 = -2/3 x + 2

4x-2/3 x = 12-2

10/3 x = 10

10x = 30

x = 30/10 = 3

Therefore, at 3 quects each person will have when they have the same amount
