Answer:

1st cylinder: 3541.9 square mm

2nd cylinder: 439.6 square cm

Step-by-step explanation:

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(12)^{2} + 2(3.14)(12)(35)\\s = 6.28(144) + 6.28(420)\\s = 904.32 + 2637.6\\s = 3541.92\\s = 3541.9

Second cylinder.

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(7)^{2} + 2(3.14)(7)(3)\\s = 6.28(49) + 6.28(21)\\s = 307.72 + 131.88\\s = 439.6

R^2+3r+5-r^3/r is a quadratic/cubic/linear polynomial?
Sergeu [11.5K]

r^2+3r+5-r^3/r is  a linear polynomial

S<u>tep-by-step explanatio</u>n:

based on the highest power of the variables of a polynomial, it can be classified as linear,polynomial, quadratic polynomial,cubic polynomial etc.

In a linear polynomial, the highest power of the variable is 1. The general form of a linear polynomial is ax+b

In a quadratic polynomial, the highest power of the variables is 2.The general form of quadratic polynomial is ax^2+bx+c

In a cubic polynomial,the highest power of variable is 3.The general form of cubic polynomial is ax^3+bx^2+cx+d.

Take the given question and simplify it

r^2+3r+5-r^3/r=r^2+3r+5-r^2\\=3r+5

It is of the form ax+b. Hence it is  a linear polynomial.

Simplify the expression 5+6i/4+6i<br> A) 56-6i/-20<br> B) -16-6i/-20<br> C)56-6i/52<br> D) -16-6i/52
IRISSAK [1]

Answer:

The\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.

Option (C) is correct .

Step-by-step explanation:

As the expression given in the question as follows.

= \frac{5 + 6i}{4 + 6i}

Now rationalize the expression.

= \frac{5 + 6i\times 4 - 6i}{4 + 6i\times 4 - 6i}

Using the formula

a² - b² = (a - b) (a + b)

Using in the above

= \frac{5 + 6i\times 4 - 6i}{(4)^{2} - (6i)^{2}}

= \frac{5\times 4-5\times 6i+6i\times 4-36\ i^{2}}{16 - 36(i)^{2}}

As i² = -1

= \frac{20-30i+24i+36}{16 + 36}

= \frac{56-6i}{52}

Therefore\ the\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.

Option (C) is correct .

Caroline's hair is
Ipatiy [6.2K]

The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10

<h3>What is an equation? </h3>

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

Let x represent the number of months.

For Caroline's hair:

Length = (1/5)x + 7

For Trinity's hair:

Length = (1/10)x + 10

For Caroline's hair to be at least as long as Trinity's hair, hence:

(1/5)x + 7 ≥ (1/10)x + 10

The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10

5) Find the distance between -9 and 12 on a number line.​
kati45 [8]

Answer: Hope this helps!!!

Step-by-step explanation:Absolute Value: You need to find how far away both numbers are from zero, then add these values together to see how far apart these numbers. The absolute value of nine, |-9| is 9, and |12| is 12. This means that the nine is nine spots away from zero, and twelve is twelve spots from zero. This means that the numbers are 20 units from each other.

Distance -9 is from 12 You need to find how much of an increase from nine you need to reach the twelve. So -9 + ? = 12. What number can you add to equal twelve? You can add 20 to make the equation true. (? = 20) The distance from -9 to 12 is a positive 20.

Distance from 12 to -9 This is similar to the previous example. What number can you insert to make the 12 equal the negative nine? 12 - ? = -9. The number would be -20, which means that 12 is 20 spots away from the negative nine, as it took at negative twenty to get us to the negative nine.
