What is the equation in slope-intercept form of the line

Mathematics
1 answer:
kari74 [83]3 years ago
3 0

Answer:

-5/2x+3

Step-by-step explanation:

you reciprocate the slope since you are trying to find a line perpendicular.

From this m=2/5 to -5/2

then use the formula y-y1 =m(x-x1)

then you put in the points

y - - 2= -5/2(x- 2)

y+2= -5/2x +5

-2            -2

y= -5/2+ 3

Help please!!!!!!!!!!!
ss7ja [257]

First, solve 7 times square root of 5.

7 x 2.236 = 15.652

Now find the solution above that results in 15.65.

We can quickly eliminate the top 2 as they will result in very large numbers.

The bottom problem is quick to check - simplifies to (7 + 5)/5 = 2.4. No

It looks like the next to last answer is our best bet.

Figure the square root of 196 (14) and multiply by square root of 5 (2.236).  Giving us 31.304.

Divide the result by 2.  And that gives us 15.652.

If you knew the square root of 196 was 14, it was helpful to find this quickly because 14/2 = 7 and then the other square root was the 5 from the problem.

If the parent function f(x)=\root(3)(x) is transformed to g(x)=\root(3)(x+2-4), which is the graph of g(x)?
Arisa [49]

ANSWER

A.

EXPLANATION

The parent function is

f(x) = \sqrt[3]{x}

This function is transformed to obtain

g(x) =  \sqrt[3]{x + 2}  - 4

The +2 is a horizontal translation, that shifts the graph of the parent function to the left by 2 units.

The -4 is a vertical translation, that shifts the graph of the parent function down by 4 units.

The correct option is A.

Suppose that poaching reduces the population of an endangered animal by
Sedbober [7]

Answer:

38.26 years.

Step-by-step explanation:  

We have been given that the population of an endangered animal by  reduces 8​% per year. the current population of the animal is  1700. When the population of this animal falls below  70​, its extinction is inevitable.  

Let us write the model for population of this animal (y) after x years.

Since we know that an exponential decay function is in form: y=a*(1-r)^x, where,

a= Initial value.

r = Rate in decimal form.

Let us convert our given rate in decimal form.

8\%=\frac{8}{100}=0.08

Upon substituting a= 1700 and r = 0.08 in exponential function, we will get the model of animal population as:

y=1700*(1-0.08)^x

y=1700*(0.92)^x

Let us find, when the animal population will face extinction by substituting y=70 in our function.

70=1700*(0.92)^x  

\frac{70}{1700}=\frac{1700*(0.92)^x}{1700}

0.0411764705882353=0.92^x  

Let us take natural log of both sides of our equation.

ln(0.0411764705882353)=ln(0.92^x)

ln(0.0411764705882353)=x*ln(0.92)

-3.1898882879949483163=x*-0.0833816089390511

x=\frac{-3.1898882879949483163}{-0.0833816089390511}

x=38.2564971890460849445284\approx 38.26

Therefore, the population of the animal will face extinction after 38.26 years.
