explanation:

If h (x)=√49-x², find h (0), h (-7) and h (9).​

Answers

Answer:

Step-by-step explanation:

f(0) = √49 - x^2

f(0) means that wherever you see an x on the right, you put a zero.

so f(0) = √49 - 0^2

f(0) = √49

f(0) = 7

f(-7) = √49 - x^2

Again the meaning is that where you see an x on the right, you substitute - 7 for that x.

f(-7) = √49 - (-7)^2

f(-7) = 7 - 49

f(-7) = - 42

f(9) = √49 - (9)^2

f(9) = 7 - 81

f(9) = - 74

ANSWER: 643.7


We have to find the areas of both circles, and subtract the area of the smaller one from the bigger one. That will be the answer.

Area of a circle = pi times radius^2



So


Small circle:
A = 3.14 x 18 x 18
A = 1,017.36


Bigger circle:
A = 3.14 x 23 x 23
A = 1,661.06


So then we do:

1,661.06 - 1,017.36 which equals 643.7. That’s the area of the ring.

A hemisphere-shaped bowl with radius 1 foot is filled full with chocolate. All of the chocolate is then evenly distributed between 27 congruent, smaller hemisphere-shaped molds. What is the radius of each of the smaller molds, in feet

Answers

The radius of each of the smaller molds is r = 1/3 ft. Using the volume of the given hemisphere, the required radius is calculated.

How to calculate the volume of a hemisphere?

The volume of the hemisphere is calculated by using the formula,

= [tex]\frac{2}{3}[/tex] × π × r³ cubic units

where r is the radius of the hemisphere.

Calculation:

It is given that,

A hemisphere-shaped bowl with a radius r = 1 ft is filled with chocolate.

So, the volume of the bowl is

V =  [tex]\frac{2}{3}[/tex] × π × (1)³

  =  [tex]\frac{2}{3}[/tex] × π cubic feets

The volume of each smaller hemisphere-shaped mold =  [tex]\frac{2}{3}[/tex] × π × r³ cubic units

So, for 27 molds, the volume = 27 × [tex]\frac{2}{3}[/tex] × π × r³ cubic units

All of the chocolate is then evenly distributed between 27 congruent, smaller hemisphere-shaped molds.

Then,

[tex]\frac{2}{3}[/tex] × π = 27 × [tex]\frac{2}{3}[/tex] × π × r³

⇒ r³ = 1/27

⇒ r = 1/3 ft

Therefore, the required radius of each of the smaller molds is 1/3 foot.

30 A club of 12 people would like to choose people for the offices of president, a vice president, and a secretary. How many different ways are there to select the officers so that only one person holds each office?

Answers

1320 different ways are there to select the officers so that only one person holds each office given that the club has 12 people who would like to choose people for the offices of president, a vice president, and a secretary. This can be obtained by using the formula of permutation.

How many different ways are there to select the officers so that only one person holds each office?

Total number of people in the club = 12

total number of positions = (president, vice president, secretary) = 3

From 12 people 3 people are taken at a time.

That is, using the formula for permutation we get,

ⁿPₓ = [tex]\frac{n!}{(n-x)!}[/tex]

Here n = 12 and x = 3

P(12,3)= 12!/(12-3)! =12!/9! = 10×11×12 = 1320

Hence 1320 different ways are there to select the officers so that only one person holds each office given that the club has 12 people who would like to choose people for the offices of president, a vice president, and a secretary.

If they win the first contract, the probability of winning the second is 73%. However, if they lose the first contract, the president thinks that the probability of winning the second contract decreases to 46%. A. What is the probability that they win both contracts

Answers

The probability that they win both contracts is 33% if there is a 45% probability of winning the first contract and the probability of winning the second contract after winning the first contract.

What is probability?

Probability is the rate of successful outcomes to the total outcomes of an event.

P(E) = n(E)/n(S)

Where E -event, n(E) - successful/favorable outcomes of event E, and n(S) - total outcomes of the event.

Calculation:

It is given that,

An aerospace company has submitted bids on two separate federal government defense contracts.

The probability of winning the first contract is - 45%

The probability of winning the second contract if they win the first contract is  - 73%

The probability of winning the second contract if they lose the first contact is - 45%

So, the probability that they win both contracts is

= (probability of winning the first contract) × (probability of winning the second contract)

= 0.45 × 0.73

= 0.3285 ≅ 0.33

Step-by-step explanation:

We can simplify the question by using the radical rule to rewrite it as
6^1/3 ÷ 6^1/4

Then we use exponent rule which states that when we are dividing exponents of the same base, we have to subtract them. We see that the exponents are 1/3 and 1/4. So we use basic fractional division, here's the subtraction:

= 1/3 - 1/4

A street light is mounted at the top of a 15-ft-tall pole. A man 6 ft tall walks away from the pole with a speed of 5 ftys along a straight path. How fast is the tip of his shadow moving when he is 40 ft from the pole

Answers

25/3 ft/s is speed of the tip of his shadow moving when a man is 40 ft from the pole given that a street light is mounted at the top of a 15-ft-tall pole and the man is 6 ft tall who is walking away from the pole with a speed of 5 ft/s along a straight path. This can be obtained by considering this as a right angled triangle.

How fast is the tip of his shadow moving?

Let x be the length between man and the pole, y be the distance between the tip of the shadow and the pole.

Then y - x will be the length between the man and the tip of the shadow.

Since two triangles are similar, we can write

[tex]\frac{y-x}{y} =\frac{6}{15}[/tex]

⇒15(y-x) = 6y

15 y - 15 x = 6y

9y = 15x

y = 15/9 x

y = 5/3 x

Differentiate both sides

dy/dt = 5/3 dx/dt

dy/dt is the speed of the tip of the shadow, dx/dt is the speed of the man.

Given that dx/dt = 5 ft/s

Thus dy/dt = (5/3)×5 ft/s

dy/dt = 25/3 ft/s

Hence 25/3 ft/s is speed of the tip of his shadow moving when a man is 40 ft from the pole given that a street light is mounted at the top of a 15-ft-tall pole and the man is 6 ft tall who is walking away from the pole with a speed of 5 ft/s along a straight path.

Balu had a collection of coins. 1/2 of the coins are from asian countries, 1/3 of them from european countries, 36 are from america, how many asian coins are there

Answers

The total number of coins Balu had in his collection was 216 coins, computed using the linear equation in one variable, x = x/2 + x/3 + 36.

Asian coins were 1/2 a fraction of this, that is, (1/2)*216 = 108 coins.

We assume the total coins with Balu to be x.

The fraction of coins from Asian countries = 1/2.

Thus, the number of coins from the Asian countries = 1/2 of x = x/2.

The fraction of coins from European countries = 1/3.

Thus, the number of coins from the European countries = 1/3 of x = x/3.

The number of coins from America = 36.

Thus, the total number of coins = x/2 + x/3 + 36.

But, we assumed that the total number of coins is x.

Thus, we get a linear equation in one variable as follows:

x = x/2 + x/3 + 36.

We solve this equation as follows:

x = x/2 + x/3 + 36,

or, x - x/2 - x/3 = 36,

or, (6x - 3x - 2x)/6 = 36,

or, x/6 = 36,

or, x = 36*6 = 216.

Thus, the total number of coins Balu had in his collection was 216 coins, computed using the linear equation in one variable, x = x/2 + x/3 + 36.

Asian coins were 1/2 a fraction of this, that is, (1/2)*216 = 108 coins.

We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.To find the area of community pool we will use area of pentagon formula.[tex]Area of pentagon=\frac{1}{2} a * p$[/tex] , where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.

Let us find the perimeter of our given pentagon by multiplying each side length by 5.

[tex]Perimeter of community pool $=5 \times 23.62\\Perimeter of community pool $=118.1$[/tex]

Now let us find apothem of our pentagon by using Pythagoras theorem.  

[tex]a^{2}=20.10^{2}-11.81^{2}\\$a^{2}=404.01-139.4761\\$a^{2}=264.5339\\$a=\sqrt{264.5339}\\$a=16.2645$[/tex]

Upon substituting our given values in above formula we will get,

[tex]Area of community pool =\frac{1}{2} \times 16.2645 \times 118.1\\Area of community pool $=8.13224907 \times 118.1\\Area of community pool $=960.418615627971 \approx 960.42$[/tex]

Therefore, the area of the pool that needs to be covered is 960.42 square feet.

Step-by-step explanation:

Find the volume of the cone.
either enter an exact answer in terms of it or use 3.14 for i and round your final answer to the nearest
hundredth.

Answers

The volume of the cone of  radius 5 units and height 3 units is 78 cubic units.

Given radius of cone 5 units and height of cone be 3 units.

We are required to find the volume of cone.

Volume is the amount of substance that a container can hold in its capacity.

Formula of cone is 1/3 *π[tex]r^{2} h[/tex] in which  r is radius and h is height of cone.

We have to just put the values in formula.

Volume=1/3 *π[tex]5^{2} 3[/tex]

=25*3π/3

=75π/3

=25π

Put π=3.14 as said in the question.

=25*3.14

=78.5 cubic units.

After rounding we will get 78.

Hence the volume of cone whose radius is 5 units and height is 3 units is to be 78 cubic units.

Question is incomplete as it should include the figure.

Which of the following exponential functions is represented by the graph?
OA)
A) f(x) = -2x
B) f(x) = 2x
C) f(x) = (¹/2)-x
OD) f(x) = (¹/2)*

Answers

Answer:

D) f(x) = (1/2)^x

Step-by-step explanation:

at least that is what I think answer D is supposed to be.

I guess the other answer options are actually

A) f(x) = -2^x

B) f(x) = 2^x

C) f(x) = (1/2)^-x

let's look at the most interesting point here : (1, 1/2).

when x=1, then y = 1/2

A fails. because for x = 1 we get y = -2.

B fails. because for x = 1 we get y = 2.

C fails. because for x = 1 we get (1/2)^-1

and that is 1 / 1/2 = 2

so, the only function giving us (1, 1/2) is D, as

(1/2)¹ = 1/2

An artist charges a $50 supply fee, plus $35 per hour for classes. write an equation to represent the total cost, c, based on the number of hours, h, of the lesson. what will be the total cost if you take a 5 hour art lesson?

Answers

The total cost in 5 hours is $225

Given that the charges of a supply fee of an artist is $50

The charges per hour classes is $35

The total cost is expressed by c

The number of hours expressed by h

We need to calculate the total cost in 5 hour lesson

As per the given statement ,

C= 50 +35h

Where h is the number of hours

h = 5 hours

C = 50 + 35h

C = 50 + 35(5)

C = 50 +175

C = $225
