ANSWER

The average speed is 7m/s.

EXPLANATION

If the dot ran from -66 to -17, then the distance covered is

| - 17 -  - 66|  = 49

The average speed

=  \frac{distance \: covered}{time \: taken}

Substitute

=  \frac{49}{7}

Simplify;

= 7m {s}^{ - 1}

In the 1980s an average mortgage rate was around 18.5 how much less per month would a 150000 30 year mortgage by today if the cu
lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

Sean is driving to visit his friend in another state. In the first hour, he travels 1/5 of the total distance. Second hour he tr
astra-53 [7]

Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = x

On first hour distance traveled in miles is = \frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x

Distance left to cover  after first hour = x-\frac{1}{5}x

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = 34\ miles+194\ miles = 228 miles

Thus, the equation can be given as:

⇒ x-\frac{1}{5}x=228

Multiplying each term with 5 to remove fractions.

⇒ 5x-5.\frac{1}{5}x=5\times228

⇒ 5x-x=5\times228

⇒ 4x=1140

Dividing both sides by 4.

⇒ \frac{4x}{4}=\frac{1140}{4}

∴ x=285

Thus, the friends live 285 miles apart.

Find the values of y = r(x) = ∛x for
eduard
We're being asked to find the values of y for \sqrt[3]{x} for specific values of x. Basically, we are taking the cube roots of these numbers.



r(-2.197) = \sqrt[3]{-2.197} = -1.3\\\\ r(-1.331) = \sqrt[3]{-1.331} = -1.1\\\\ r(0) = \sqrt[3]{0} = 0 \\\\ r(1.331) = \sqrt[3]{1.331} = 1.1\\\\r(2.197) = \sqrt[3]{2.197} = 1.3\\\\r(-3.375) = \sqrt[3]{-3.375} = 1.5\\\\r(4.913) = \sqrt[3]{4.913} = 1.7\\\\
