Answer:

Perpendicular lines have slope that are negative reciprocals.

The slope of the perpendicular line is M = -1/3.

Step-by-step explanation:

(4,-1) --> X = 4, Y = -1, M = -1/3

y = Mx + b

-1 = (-1/3)*4 + b

-1 = (-4/3) + b

-3/3 = (-4/3) + b

-3 = -4 + 3b

1 = 3b

b = 1/3

y = (-1/3)X + 1/3

<h3>Answer : 8 1/5</h3>

7 / x-4 = 3 / 5

x - 4 = 7 × 3/5

x - 4 = 21/5

x = 21/5 + 4

x = 41/5 = 8 1/5

Which equation represents an exponential function that passes through the point (2, 36)?

sesenic [268]

Answer:

The exponential function that passes through (2,36) is:

$f(x)=4\times 3^x$ .

Step-by-step explanation:

We are asked to find which function passes through the point (2,36).

i.e. we will put the input value '2' in the following given functions and check which gives the output value as '36'.

$f(x)=4\times 3^x$

now we put x=2.

$f(2)=4\times 3^2\\\\f(2)=4\times 9\\\\f(2)=36$

hence option 1 is correct.

$f(x)=4\times x^3$

Now we put x=2.

$f(2)=4\times 2^3\\\\f(2)=4\times 8\\\\f(2)=32$

Hence, option 2 is incorrect.

$f(x)=6\times 3^x$

Now we put x=2

$f(2)=6\times 3^2\\\\f(2)=6\times 9\\\\f(x)=54$

Hence, option 3 is incorrect.

$f(x)=6\times x^3$

Now we put x=2.

$f(2)=6\times 2^3\\\\f(2)=6\times 8\\\\f(2)=48$

Hence, option 4 is incorrect.

Hence, option 1) is correct.

i.e. The exponential function that passes through (2,36) is:

$f(x)=4\times 3^x$

Last year the population of Spoon Forks grew from 1250 to 1300. If the population of the town grows by the same percent this yea

Reptile [31]

Answer:

1352

Step-by-step explanation:

Firstly, we get the percentage growth last year. This is calculated as:

(1300-1250)/1250 * 100

= 4%

Now, we are assuming the growth rate is constant. So let’s calculate a 4% growth rate for this year. That would be:

4/100 * 1,300 = 52

The population this year would thus be 1300 + 52 = 1352
