Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25

Answer:
139.25 m²
Step-by-step explanation:
Area of the square = 10 * 10 = 100 m²
Radius of the semicircle = 5 m
Area of the semicircle = π(5)²/2 = 39.25 m²
Total area = 100 + 39.25 = 139.25 m²

What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
A) x – 6
B) x – 3
C) x + 1
D) x + 6
Answer:
D. x + 6
Step-by-step explanation:
In the given graph, we have 3 x-intercepts values, which are points at which the line intercepts the x-axis. They are, -6, -3 and 0.
Each of these x-intercepts can be written as a factor of a polynomial function as follows:
x = -6
x = -6 + 6
x + 6 = 0
x = -3
x = -3 + 3
x + 3 = 0
x = 0
Therefore, the factor of the polynomial function must be: x + 6
Hi I really need help please help me
Answer:
B
Step-by-step explanation:
Y-intercept is where a graph crosses the y-axis at x=0
f(x) = 6x^2 + 18x + 3
f(0) = 6(0)^2 + 18(0) + 3 = 3
From the plot, g(x) at x=0 is 6.
So the answer is B. g has a greater y-intercept than f.
For f(x)
[tex]\\ \rm\rightarrowtail y=6x^2+18x+3[/tex]
Put x =0[tex]\\ \rm\rightarrowtail y=6(0)^2+18(0)+3=3[/tex]
Y intercept at 3From the graph
y intercept of g(x)=6
So option B is correct

find 3 consecutive integers if three times the first integer is two times the third.
Answer:
4, 5, and 6
Step-by-step explanation:
Three Consecutive integers are x, x+1, x+2
We are given 3 times the first integer is 2 times the third
So
3x = 2(x+2)
Solve for x
3x = 2x+4
x = 4 (first integer)
so the 3 integers are 4, 5, and 6

You pull out the plug from the bathtub. After 40 seconds, there are 13 gallons of water left in the tub. One minute after you pull the plug, there are 10 gallons left.
Assume that the number of gallons varies linearly with the time since the plug was pulled.
Write the particular equation expressing the number of gallons (g) left in the tub in terms of the number of seconds (s) since you pulled the plug.
Answer:
g = -3/20s + 19Step-by-step explanation:
Let's assume this is a function
The points are
(40, 13) and (60, 10)Since it is linear relation, we'll get the slope intercept form
g = ms + b, where g- number of gallons, s- time in seconds, b- y interceptUsing the points, let's calculate the formula
m = (10 - 13)/(60 - 40) = -3/2010 = -3/20*60 + b10 = - 9 + bb = 19So the formula is:
g = -3/20s + 19. Day before today Tuesday.

might describe Peter's drawing?
I. AC and AP are parallel.
II. PAC is an angle
III. AC and AP are perpendicular
A. I and II
B. II and III
C. I and 111
D. I, II, and III
Answer:
Option B: II & III
Step-by-step explanation:
We are told that Peter drew two rays which are AC and AP.
We are told that A is a common endpoint.
If A is a common endpoint, it means the 2 rays interaction point at A is at an angle.
The angle could also be 90° which means it's possible that the rays AC and AP are perpendicular.
Thus, the correct statements that describe his drawing are: II & III

F(x)=-14/x^2 average rate
Answer:
I am assuming that the function is f(x)=20(14)x, if it is
then f(x)=280x , The average rate of change between x =1 and x=2
is the slope of the function between the 2 and 1
Average rate of change = [f(b)-f(a)/b-a] let a and b be x and y
f(a)=f(x)=f(1)=280x1=280
f(b)=f(y)=f(2)=280x2=560
Average rate of change = [f(b)-f(a)/b-a]=[(560-280)/(2-1)]=280

Answer:
P (A|C) = 0.39

The data provided is as follows:
Blood Group
O A B AB Total
1) 0.082 0.101 0.005 0.004 0.192
Ethnic Group 2) 0.140 0.141 0.018 0.009 0.578

The event C = {Ethnic group 3 is selected}
Compute the value of P (A|C) as follows:
[tex]P(A|C)=\frac{P(A\cap C)}{P(C)}=\frac{0.195}{0.5}=0.39[/tex]
If we know that the individual came from ethnic group 3, the probability that he has type A is given by P(A | C) = 0.39.
Compute the value of P (C|A) as follows:
