A laser pointer in the shape of a cylinder is 13 centimeters long with a radius of 1 centimeter. It has a cone tip with a height of 3 centimeters. What is the volume of the stylus? Express your answer in terms of π.
Answers
The volume of the cylindrical stylus having a conical tip will be V=14π [tex]cm^{3}[/tex]
What will be the volume of the stylus?It is given that
height of the cylindrical shape of the stylus h=13cm
radius of stylus r= 1cm
height of the conical tip of the stylus h=3cm
Now we know that the
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
The volume of the cone = [tex]\dfrac{1}{3} \pi r^{2} h[/tex]
The total volume of the stylus = volume of the cylinder +volume of the cone
Total volume = [tex]\pi r^{2} h + \fdrac{1}{3} \pi r^{2} h[/tex]
now by putting the values
[tex]=\pi (13)(1)^{2} +\dfrac{1}{3} \pi (1)^{2} (3)[/tex]
So the total volume = [tex]14\pi cm^{3}[/tex]
Thus the volume of the cylindrical stylus having a conical tip will be V=14π [tex]cm^{3}[/tex]

Answers
The expression 7(6) + 14=56 will be equal to 7(a + 2) at a = 6
What will be the expression equivalent to 7(a + 2) at a = 6?We have an expression
7(a + 2)
Now at a = 6, its value will be
7 (6 + 2) = 7 × 8 = 56
Now from the given options we can see that
7 (6)=42
9 (6)=54
7 (6) + 2=44
7(6) + 14 = 42 + 14 = 56
Thus the expression 7(6) + 14=56 will be equal to 7(a + 2) at a = 6

Three students each have 10.2 pounds of laundry to wash. A fourth student has 3.4 pounds
of laundry to wash. How many pounds of laundry do they have in total? (give steps please!)
Answers
Answer:
34 pounds
Step-by-step explanation:
hi again!
so if three students have 10.2 to wash, we can find how many pounds the 3 students have in total by multiplying 10.2*3, because that is the same as doing 10.2+10.2+10.2. this gives us a result of 30.6 points for the three students.
now if the fourth student has 3.4 pounds, we just add that to 30.6
thus we have 30.6+3.4 which equals your answer, 34.

How would a bigger down payment be beneficial to borrowers? a. A bigger down payment is only beneficial for a person applying for a home loan. B. A bigger down payment is essentially a bribe to the dealership, guaranteeing a few extra bells and whistles for free. C. A bigger down payment means that the borrower has more money, and can afford a bigger loan. D. A bigger down payment is money paid toward principal, interest free, which also decreases the amount paid monthly.
Answers
The correct option is D, A bigger down payment is money paid toward principal, interest-free, which also decreases the amount paid monthly.
What is interest?The amount of money a lender or financial organization earns for lending out money is known as interest.
We know that monthly payments include the interest on the principal amount that is not been paid during the purchase of an item, if the down payment is more than the principal amount that the customer does not pay will decrease which will decrease the loan amount, thus, the interest on the principal amount will decrease as well.
Now, as the interest and the principal amount have both is been reduced, therefore, the monthly instalment(monthly payment) will be reduced as well.
Hence, the correct option is D, A bigger down payment is money paid toward principal, interest-free, which also decreases the amount paid monthly.

Answers
Answer:

Step-by-step explanation:
when using the distributive property multiply 1/3 into everything inside the parentheses.
So your first step is to multiply 1/3 to 9.
[tex]\frac{1}{3}[/tex] x [tex]\frac{9}{1}[/tex] keeping in mind that all numbers are divisible by one.
then you get your answer of [tex]\frac{9}{3}[/tex] which equals 3.
From there you want to distribute the [tex]\frac{1}{3}[/tex] into k but you don't know what "k" is so you'll have an answer of [tex]\frac{1}{3}[/tex]k meaning that k whatever it is. Is being multiplied by the [tex]\frac{1}{3}[/tex].

Find the Range of this function.
Answers
Answer:
y ≥ -6
Step-by-step explanation:
Hello!
The domain is the interval in which the graph is located vertically on the coordinate plane.
The range is the interval in which the graph is located horizontally on the graph.
Since we are finding the range of the graph, we draw a horizontal line at the lowest point of that graph. We can see that the line is y=-6 because the lowest point given by that horizontal line is -6.
Now that we know that it is the lowest point, we must find the highest point of the graph. Looking at it, we can see that it goes infinitely up, or it continues above -6. This means that the graph hits every horizontal line above -6, or all the values above -6.
The interval would be -6 ≤ y ≤ ∞ (greater than or equal to sign because the graph includes the point) or we can simply rewrite it as all values above -6 or y ≥ -6.
