Answer:

Rational.

Step-by-step explanation:

A rational number doesn't have a repeating decimal. -2 is a rational number.

Answer: irrational

Step-by-step explanation:

In other words, a rational number is negative, if its numerator and denominator are of the opposite signs. Each of the rational numbers -1/6, 2/-7, -30/11, 13/-19, -15/23 are negative rationals, but -11/-18, 2/5, -3/-5, 1/3 are not negative rationals. 1. ...

Answer:

$437

Step-by-step explanation:

There are 7 days in a week.

Let's stop at the last even number, the 6th day.

Tuesday is four days away from Sunday, so multiply 122 by 3.

\(\mathrm{122}\) × \(3\) = \(366\)

Finally, we are at the 7th day. There is no 8th day in a week, so divide 122 by 2.

\(122\) ÷ \(2\) \(=61\)

Now, let's add 61 to 366. We get $437, and that is our answer.

Hope this helps!

1) The potato reaches a height of 96 feet at a second after launch.

2) The potato cannot be in the air at t = 8 seconds.

3) The potato will reach a height of 120 feet at t = 4.295 seconds and t = 1.455 seconds.

4) The potato will hit the ground at t = 5.960 seconds.

In this question we find the case of a potato being thrown to the air, the height of the potato as a function of time is a quadratic equation. The first part consists in determining the height of the potato a second after its launch:

h(1) = - 16 · 1² + 92 · 1 + 20

h(1) = - 16 + 92 + 20

h(1) = 96

In the second part we must determine if the potato is still in the air after 8 seconds:

h(8) = - 16 · 8² + 92 · 8 + 20

h(8) = - 268

Since h(8) < 0, then the potato cannot be in the air when t = 8 seconds.

The third part asks us if the potato reaches a height of 120 feet and, if possible, when it will happen:

120 = - 16 · t² + 92 · t + 20

- 16 · t² + 92 · t - 100 = 0

16 · t² - 92 · t + 100 = 0

16 · [t² - (23 / 4) · t + 25 / 4] = 0

t₁ = 4.295 s or t₂ = 1.455 s.

Finally, we determine when the potato will hit the ground:

- 16 · t² + 92 · t + 20 = 0

t₁ = 5.960 s or t₂ = - 0.210 s

The potato will hit the ground at t = 5.960 seconds.

Answer:

(4p x 4) x 2 = 16p x 2 = 32p

Step-by-step explanation:

The required simplification is (4p⁴)² = 256p⁸.

Some of the rules of exponents are as follows,

The product of two exponents having the same power is equal to the power of their base multiplied.

The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.

The given expression is  as below,

(4p⁴)²

Without using the exponents the given expression can be simplified as follows,

The power to any number simply means that the number will be multiplied to itself as many number of times. this basic rule is used to obtain result as,

(4p⁴)²

= (4p × 4p × 4p × 4p)²

= (16p⁴)²

= 16p⁴ × 16p⁴

= 256 × (p × p × p × p × p × p × p × p)

= 256p⁸

Hence, the given expression can be simplified as  256p⁸.

Answer:

160

Step-by-step explanation:

there are 24 first class seats. 15% of the total number is 24. that would mean 5% of the total number is 8. 20 times 8 is 160.

A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.

B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.

how many months for the cost to be the same?

\(\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4\)

well, since the cost for both is the same, we can just get A's, knowing that B is the same

\(12+28(4)\implies 12+112\implies 124\)

The cost of one hosta is approximately $7 and the cost of one geranium is approximately $4.

To find the cost of one hosta and one geranium, we can set up a system of equations based on the given information.

Let's assume the cost of one hosta is represented by 'h' and the cost of one geranium is represented by 'g'.

From the information given, we can set up the following equations:

Eugene's spending:

18h + 6g = $150

Jessica's spending:

7h + 16g = $113

We can now solve this system of equations to find the values of 'h' and 'g'.

Multiplying the first equation by 2 and the second equation by 3 to eliminate 'g', we get:

36h + 12g = $300

21h + 48g = $339

Now, we can subtract the second equation from the first to eliminate 'h':

(36h + 12g) - (21h + 48g) = $300 - $339

36h - 21h + 12g - 48g = -$39

15h - 36g = -$39

Simplifying further, we have:

15h - 36g = -$39

Now we can solve this equation for 'h' and substitute the value back into any of the original equations to find 'g'.

Let's solve for 'h':

15h = 36g - $39

h = (36g - $39) / 15

Substituting this value of 'h' into Eugene's equation:

18[(36g - $39) / 15] + 6g = $150

(648g - $702) / 15 + 6g = $150

648g - $702 + 90g = $150 * 15

738g - $702 = $2250

738g = $2250 + $702

738g = $2952

g = $2952 / 738

g ≈ $4

Now, substituting the value of 'g' back into Eugene's equation:

18h + 6($4) = $150

18h + $24 = $150

18h = $150 - $24

18h = $126

h = $126 / 18

h ≈ $7

Therefore, the cost of one hosta is approximately $7 and the cost of one geranium is approximately $4.

Answer:

Answer:

Always the same

Step-by-step explanation:

The temperature at the beginning of a change of state is always the same as the temperature at the end.

This is because phase change is an isothermal process. it means that all the energy absorbed during the phase change process is utilized in the breaking of the bonds in the compound as it changes from one state of matter to another.

As a result, no increase in the temperature of the material will be detected by the thermometer.
