Find the equation of the exponential function represented by the table below:

Mathematics
1 answer:
Elden [556K]3 years ago
7 0

Answer:

The equation of the exponential function represented by the table will be:

f(x)= 2(4)^{x}

Step-by-step explanation:

We know the equation of exponential function such as

f(x) = ab^{x}

Put x=0, and y=2 in the function

2 = ab^{0}

2 = a

Also x=1, and y=8 in the function

8 = 2b^{1}

b=4

Thus,

f(x) = ab^{x}

        = 2(4)^{x}

Therefore, the equation of the exponential function represented by the table will be:

f(x)= 2(4)^{x}

Write an equation of a line that passes through (3, -1) and is parallel and perpendicular to y = 6x - 4
Serhud [2]

Here,

y=mx+c

the slope of the line 6x+4y= -16 is -20.

if the two lines are perpendicular, the slope of 1st line * slope of second line=-1

the slope of the 2nd line is -1/2

y-y1=m(x-x1)

y-13=-1/2(x- -18)

when you solve, you get the equation of the line as 2y+x=50

In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.

If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.

The difference of two numbers is 3. their sum is 14. find the two numbers. (show work please)
Artemon [7]
Let's say the larger number is x. that means that the smaller number is x - 3. since you know their sum is x + x - 3, and that is equal to 14. so you have the equation x + x - 3 = 14. combine like terms (x) to get 2x - 3 = 14. add three to both sides to get 2x = 17. divide both sides by two to get x = 17/2. so the larger number is 17/2, and the larger number is 11/2 (17/2 - 3 = 11/2)

Mr. Tolin purchased a used car for $2,816, which was 12% off the asking price. What was the asking price of the used car?
Nina [5.8K]

Answer:

Original price= $3,200

Step-by-step explanation:

Giving the following information:

Purchase price= $2,816

Discount rate= 12% = 0.12

<u>To calculate the original price, we need to use the following formula:</u>

Original price= purchase price / (1 - discount rate)

Original price= 2,816 / 0.88

Original price= $3,200
