Which of the following graphs is described by the function given below? y=x^2-6x-7

Mathematics

mojhsa [17]3 years ago

Answer:

Step-by-step explanation:

If we have to find the graph described by a function then we should try to convert the equation into vertex form first.

Here given equation of the parabola is y = x² - 6x - 7

Then we will convert this equation into the vertex form.

y = x² - 2×(3x) + 9 - 16

y = (x - 3)² - 16

So the vertex of the given parabola is (3, -16).

Now we have understood that parent function y = x² have been shifted 3 units right and 16 units down.

Therefore, the given translated parabola will be in the shape of attached figure.

Answer:

gradient is 8 and y intercept is 0

Step-by-step explanation:

y=mc+b

take one pair of corridants:

8=1m+b

m=8 (change in y values/changes in x values)

8=1x8+b

do the equation

y=0

Have a nice day!!!!!!!!! :-)

About 79,000 people live in a circular region with a population density of about 513 people per square mile. Find the radius of
Natalija [7]

To solve this problem, let us first assign some variables. Let us say that:

d = represents the population density of the circular region (in units of 513 people per square mile)

p = represents the population of the circular region (in units of people)

r = is the radius of the circular region

 

Now we can see that if we divide p by d, we can get a value which has a units of square mile. Thus the area of the region, hence:

Area = 79,000 people / (513 people per square mile)

Area = 154 square mile

 

The area of a circle has the formula:

Area = π r^2

Therefore calculating for r:

154 square mile = π r^2

r = 7 miles            (ANSWER)
