Answer:

1056.24 cm^3

Step-by-step explanation:

The volume of a cylinder is $\pi r^2h$ . The problem says to use $\pi$ =3.14

Plug in your numbers $3.14*4.8^2*14.6=1056.24$

A textbook company keeps track of its daily cost for printing whole textbooks to different schools, but can only print up to 500

seraphim [82]

Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.

Find 15 + (-72) show your work I will give Brainly! Pls help!

Umnica [9.8K]

Answer: -57

Step-by-step explanation:

15 + ( - 72)

Distribute

15 - 72

When this happens, you subtract the smaller number by the bigger one, then put the sign that was on the bigger number on what you get.

72 - 15 = 57

Put a negative sign on 57

-57

15 + (-72) = -57

Select the correct answer. Which point lies on the circle represented by the equation (x + 7)2 + (y − 10)2 = 132? A. (5,12) B. (

Feliz [49]

Answer:

B. (-7,-3)

Step-by-step explanation:

Given the circle: $(x + 7)^2 + (y - 10)^2 = 13^2$

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

Option A (5,12)

When x=5, y=12

$(5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2$

Option B (-7,-3)

When x=-7, y=-3

$(-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2$

Option C (-6,-10)

When x=-6, y=-10

$(-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2$

Option D (6,23)

When x=6, y=23

$(6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2$

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.
