Since the lines have the same slopes, hence they are parallel lines

<h3>How to determine the relationship between lines</h3>

We can determine the relations by knowing the slopes of the line

For the line with coordinates (9, –5) and (5, –2)

Slope = -2+5/5-9
Slope = -3/4

For the line with coordinates (–4, –2) and (–8, 1)

Slope = 1+2/-8+4
Slope = -3/4

Since the lines have the same slopes, hence they are parallel lines

The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.

MariettaO [177]

9514 1404 393

Answer:

Step-by-step explanation:

Each year, the value is multiplied by 1-15% = 85% = 0.85. This is correctly shown in the function ...

f(t)=21,000(0.85)^t

Evaluate the riemann sum for f(x) = 3 − 1 2 x, 2 ≤ x ≤ 14, with six subintervals, taking the sample points to be left endpoints.

Dahasolnce [82]

<span>Answer: First step is to find out what your x values are. The length of the interval from 2 to 14 is 12. Divide it into six equal parts, which is 2. Then the x points for the left endpoints are: 2, 4, 6, 8, 10, 12 (and the last rectangle goes from 12 to 14), but you don't use 14 unless you are doing right endpoints or trapezoids or something.) Next step is to find the areas of the rectangles. It is just the base times the height, and the height is the function value of the x value, since the rectangle sits on the x axis and extends vertically up or down to the graph of the function. In integrals an area below the axis is considered to contribute a negative quantity to the integral, so we will do the same for rectangles that extend below the x axis. f(2) = 3 - (1/2) 2 = 3 - 1 = 2 f(4) = 3 - 4/2 = 1 f(6) = 3 - 6/2 = 0 f(8) = 3 - 8/2 = -1 f(10) = 3 - 10/2 = -2 f(12) = 3 - 12/2 = -3 That should be in a table. Next to it you write the area, multiplied by -1 if f(x) < 0 (I'm saying that because areas are always positive.) That gives 4, 2, 0, -2, -4, -6 for the six rectangles. Add all that up and it mostly cancels but you get -6 for the final answer. I have explained as I went along. You do not have to explain so much when you give the answer on a test or homework. Just the computations and not so many words.</span>

suppose that this individual now decides to give one-eighth of a percent of his new net worth to charity. how many dollars are g

jolli1 [7]

The number of the dollars given to the charity will be $99,000,000.

<h3>What is the percentage?</h3>

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that someone has a net worth of 7.92×10¹⁰.Suppose that this individual now decides to give one-eighth of a percent of his new net worth to charity.

The number of dollars given to the charity will be calculated as below:-

Networth: 7.92 × 10¹⁰.

The percentage given to the charity is:-

1/8 %= 0.125 % = 0.00125 × networth

The number of dollars given to the charity is:-

Number of dollars = 0.00125 × 7.92 × 10¹⁰.

Number of dollars = $99,000,000.

Therefore, the number of dollars given to the charity will be $99,000,000.

The complete question is given below:-

If someone has a net worth of 7.92 × 10¹⁰.Suppose that this individual now decides to give one-eighth of a percent of his new net worth to charity. How many dollars are given to charity?
