I need help ASAP. The cone shown has a 3 in radius and 7 in height. What is the volume of the composite figure?
Answers
Volume = 4/3 pi (3)^2
Volume = 113.1
But there is a half sphere so the volume will be 113.1/2 = 56.55
Volume of a cone = (1/3) pi x r^2 x h
Volume = 1/3 x pi x 3^2 x 7
Volume = 65.97
Total volume = 56.55 + 65.97 = 122.52 in^3
So the correct option is option B

Answers
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

The point W(-5, 5) is translated 5 units right and 9 units down. What are the coordinates of the resulting point, W′?
Answers
Answer:
W(0,-4)
Step-by-step explanation:
By translating right, we add the translation unit to the given coordinate of the x-axis
By translating downwards, we have to subtract the translation unit from the given coordinate of the y-axis
So from what we have here;
We are going to add 5 to the x-axis value and subtract 9 from the y-axis value
Thus, we have it that;
W’ (-5 + 5, 5 -9)
W’ (0,-4)

If a candy machine contains 76 green candies, 42 orange candies, 58 red
candies, and 24 yellow candies, what is the probability that a candy chosen at
random will be red?
Answers
Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
0.29 is the probability that a candy chosen at random will be red.
What is probability?The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.
A machine contains = 76 green candies
B machine contains = 42 orange candies
C machine contains = 58 red candies
D machine contains = 24 yellow candies
Probability = 58 / 76 + 42+ 58+ 24
= 58 / 200
= 0.29
0.29 is the probability that a candy chosen at random will be red.

y= 1.1x – 4.2
y= 1.1x² + 4.2x – 4.9
y= 1.1x² + 4.2x + 4.9
y = 1.1x + 4.2

Answer:
Y= 1.1x^2 + 4.2x - 4.9
Step-by-step explanation:
It told me I got it correct.
An equation is formed of two equal expressions. The equation that passes through each of the data sets is y= 1.1x² + 4.2x – 4.9. Hence, the correct option is B.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To find the equation that best represents this data set, plot each of the data on the graph, and plot each of the equations as well.
The other way is to check if all the data point when substituted into the equation than it satisfies the equation or not.
Thus, the equation that passes through each of the data sets is y= 1.1x² + 4.2x – 4.9. Hence, the correct option is B.

Solve the system by elimination.
{y= 16x+44
{y= -x^2 +8x+28
Answers
Answer:
x= -4, y= -20
Step-by-step explanation:
y= 16x+44
(y= -x²+8x+28) * (-1)
multiply both sides by -1
y= 16x+44
-y= x²-8x-28
add the equations to eliminate y
y-y= x²+16x-8x+44-28
0= x² +8x +16 this is the same with (x+4)²=0 so x= -4
go back to the first equation and substitute x with -4 and solve for y
y= 16*(-4) +44 = -64+44 = -20

Answer: tanA=3/4
Step-by-step explanation: If cosA=4/5 then
sinA=√(1−cos2A) {Because sin^2A+cos^2A=1}
=>sinA=√(1−16/25)
=>sinA=√(9/25)
=>sinA=3/5
Now as tanA=sinA/cosA
=>tanA=3/5×5/4 {Because 1/cosA=5/4}
=>tanA=3/4
