Semmy [17]

Answer:

4,188,790,200 cubic miles to the nearest hundred.

Step-by-step explanation:

That will be the volume of an imagined sphere with radius 1000 miles.

= 4/3 * pi * (1000)^3

= 4,188,790,200 cubic miles.

Svetradugi [14.3K]

Answer:

$4.5 \times 10^{9}$ tons.

300 times.

Step-by-step explanation:

Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.

So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e. $4.5 \times 10^{9}$ tons. (Answer)

Now, this amount is larger than $1.5 \times 10^{7}$ by $\frac{4.5 \times 10^{9} }{1.5 \times 10^{7}} = 300$ times. (Answer)

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

Setler79 [48]

The A option is correct.

<h2>Ratio and proportion</h2>

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

$\rm P = PV(\dfrac{i}{1-i})^{-n}$

The effect an increase in i.

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\$

on simplifying the equation, we get

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}$

Let n be the constant, then the equation will be

$\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i$

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.

More about the ratio and the proportion link is given below.

Let F = (2, 3). Find coordinates for three points that are equidistant from F and the y-axis. Write an equation that says P = (x

True [87]

Answer:

The equation that says P is equidistant from F and the y-axis is $P(x,y) =\left(1,\frac{3+y'}{2} \right)$ .

(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.

Step-by-step explanation:

Let $F(x,y) = (2,3)$ and $R(x,y) =(0, y')$ , where $P(x,y)$ is a point that is equidistant from F and the y-axis. The following vectorial expression must be satisfied to get the location of that point:
