Michael borrows money from his uncle, who is charging him simple interest using the formula I=prt. to figure out what the interest rate,r,is, Michael rearranges the formula to find r his new formula is r equals

Answers

Answer 1
Answer: Since the original is Interest equals price times rate times time, taking out rate still includes price times time. So, you first have R = pt. Now to insert interest, you would have to divide the interest by pt, since you invert the multiplying of Rate. So, it would be R = I/pt. Basically, this is used for finding any of the prt segment. For P, use P= I/rt. For T, use T = I/pr. And for Michael's case, to find Rate you use R = I/pt.
Answer 2
Answer:

Answer:

(I)/(Pt)= r

Step-by-step explanation:

First write down the equation they gave you:

l = Prt

You need to ask yourself what is being done to r.  r in this case is being multiplied by two variable: P and t.  To undo multiplication you divide, the set up for division:

(I)/(Pt) = (Prt)/(Pt)

I divided by the two numbers, so it would be easier.  The P and T cancels out on the right and you are left with r.  On the left, however, it stays the same because there are no like terms to solve with.  You just leave (I)/(Pt) as it is.

The result you get is:

(I)/(Pt)=r

Which describes a greater unit rate of change of Y with respect X, the equation y=0.25x or the table?

Choose 1 answer:
A. The table
B. The equation
C. The unit rates are the same

Answers

By calculating the slope, we can say that the table best describes the change in Y with respect to X.

What is slope?

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Equation of line is y = mx + c where m is the slope.

Similarly, in y = 0.25x, 0.25 is the slope.

For the table, we need to calculate slope.

m = (y2 - y1)/(x2 - x1)

m = (0.8-0.4)/(2-1)

m = 0.4

As we compare, it is clear that the slope calculated from the table is greater.

Architectural Designers is creating a schematic for a bridge over the Columbia River whose arch is in the shape of a parabola. The road, 40 feet above the river surface, represents the directrix of the parabolic arch. The focus of the parabolic arch is located 20 feet above the river surface. In the schematic, the river surface will be positioned along the x-axis and the axis of symmetry for the downward opening parabolic arch will be positioned along the y-axis. Which equation best models the parabolic arch in the schematic?

Answers

Answer:c

Step-by-step explanation:

A and D are incorrect just by the fact that they dont open downward(arch) B. Is also incorrect because the y intercept 10 doesn’t include the focus point 20 also u can use this calculator called parabola calculator to pin point focus and directive just in case u want to check my answer. C is most correct because it has intercept 30 including focus point 20...(SHOUT OUT TO ILT)
