Answer:

[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a[/tex]

Step-by-step explanation:

Given

[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})[/tex]

Required

Simplify

We have:

[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})[/tex]

Open brackets

[tex]12a^{5}-6a-10a^{3}-10a+2a^{5}+14a^{4}[/tex]

Collect like terms

[tex]12a^{5}+2a^{5}+14a^{4}-10a^{3}-6a-10a[/tex]

[tex]14a^{5}+14a^{4}-10a^{3}-16a[/tex]

Hence:

[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a[/tex]

There are 4 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars

The coins to select from are nickels, dimes, quarters, and half-dollars.

So, we have:

Coins (n) = 4

The number of coin to select is:

Coin (r) = 3

The coin combination is then calculated using:

Combination = ⁴C₃

Apply the combination formula

Combination = 4

Hence, there are 4 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars

Answer: 4[tex]\sqrt{3\\}[/tex]

Step-by-step explanation:

It is because to get rid of radical of 48, because you factor 48 and it comes out to be 12 and 4, factor of 4 is 2 x 2. Factor of 12 is 6 x 2. Simplify the 6 to

3 x 2. You find the pair and the ones that have a pare become one and go outside of the radical sign on the left. 2 has 2 pairs so it is only 2 x 2 = 4. So 4 goes outside of the radical sign. Then the number that is alone with no pair is 3 so you put the number 3 inside the radical sign.

4[tex]\sqrt{3}[/tex] is your answer.

Answer:

40 months

Step-by-step explanation:

It will take Vanessa 40 months or 3 years and 4 months to repay the bank their loan amount(without interest ofc).

Answer:

Time = 42 months

Step-by-step explanation:

[tex]Monthly \ payment = [rate + \frac{rate}{(1 + rate)^{month}-1}] \times principal[/tex]

Monthly payment = 300

Principal = 12000

[tex]Rate \% = \frac{300}{12000} \times 100 = \frac{30}{12} = \frac{5}{2} = 2.5[/tex]

Substituting and solving Months = 42 months

Answer:

C. Neither

Step-by-step explanation:

This is because the picture is showing both Exponential Growth AND Exponential Decay. As a result, it is both, but that is not an option, so neither is the answer. Hope it helps, and thank you for choosing Brainly for your question :D

Answer:

exponential decay

Step-by-step explanation:

We are multiplying by 1/3 each time

81 * 1/3 = 27

27*1/3 = 9

9*1/3 = 3

This is getting smaller so it is exponential decay

Answer:

16022 square foot

Step-by-step explanation:

The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .

We find the surface area of the cylinder

= 2πr(r + h)

r = Diameter /2 = 100 feet/2

r = 50 feet

h = 1 feet

Hence

2 × 3.14 × 50(50 + 1)

= 16022.122533 square foot

= 16022 square foot

Answer:

53/100

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

8 / 15 = 0.533

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 533

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:

0.53

Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.53 = 0.53/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.53 x 100) / (1 x 100) = 53/100

That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):

53/100

53.33% is the correct answer

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = [tex]\frac{4}{3} \pi r^{3}[/tex]. However, in this formula, 3 will be used instead of    ([tex]\pi[/tex]).

Next, plug in the information given from the problem, and the formula will look like V = [tex]\frac{4}{3}[/tex] (3) ([tex]4 in^{3}[/tex]).    

Then, solve the equation, and the answer will be 256 [tex]in^{3}[/tex].

The last line is

[tex]x = 7 + - \sqrt{30} [/tex]

The roots of f(x) are 7+root 30 and 7 -root 30.

We have given that the quadratic equation is

[tex]f(x)=x^2-14x+19[/tex]

We have to find the zeros of the given f(x)

Compaire the given equation with the general form of quadratic equation

[tex]ax^2+bx+c=0[/tex]

So we get,a=1,b=-14,c=19

We find the roots by using the quadratic formula method

[tex]x_{1,2}=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]

Use the value of a,b and c in above formula we get,

[tex]x_{1,2}=\frac{-(-14)\±\sqrt{(-14)^2-4(1)(19)} }{2(1)}[/tex]

[tex]x_{1,\:2}=\frac{-\left(-14\right)\pm \:2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]x_1=\frac{-\left(-14\right)+2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]=\frac{14+2\sqrt{30}}{2}[/tex]

[tex]=\frac{14+2\sqrt{30}}{2}[/tex]

[tex]=\frac{2\left(7+\sqrt{30}\right)}{2}[/tex]

[tex]=7+\sqrt{30}[/tex]

Similarly, we get,

[tex]x_2=\frac{-\left(-14\right)-2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]x_2=7-\sqrt{30}[/tex]

Therefore the roots of f(x) are 7+root 30 and 7 -root 30.

Answer:

12,400

Step-by-step explanation:

Let the current employees be x

65% increase in number = 0.65x

If the total number of employees after the increase is 20,460, then;

x + 0.65x = 20,460

1.65x = 20,460

x = 20,460/1.65

x = 12,400

Hence the current number of employees is 12,400
