Sketch the graph of y=(x-5) squared +3

Mathematics
1 answer:

Answer:

Part 1) The turning point is (5,3)

Part 2) The y-intercept is the point (0,28)

Part 3) The graph don't cross the x-axes

Part 4) The graph in the attached figure

Step-by-step explanation:

Part 1) State the turning point

we know that

A <u><em>turning point</em></u> is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising)

we have

y=(x-5)^2+3

This is the equation of a vertical parabola written in vertex form

The parabola open upward

The vertex represent a minimum

The vertex is the point (5,3)

therefore

The turning point is (5,3)

Part 2) Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

y=(0-5)^2+3\\y=28

The y-intercept is the point (0,28)

Part 3) Find the x-intercepts of the quadratic equation

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

(x-5)^2+3=0

(x-5)^2=-3

Remember that

i=\sqrt{-1}

so

(x-5)=\pm\sqrt{-3}

(x-5)=\pm i\sqrt{3}

x=5\pm i\sqrt{3}

The graph don't cross the x-axes

Part 4) The graph in the attached figure

What is the triangles' perimeter
DENIUS [597]
To find the perimeter of any shape, you find the sum of their side lengths.

In this case, this triangle has side lengths of 1.197, 0.764, and 1.74.
Add these, and the sum is your answer.

1.197 + 0.764 + 1.74 = 3.701

Therefore 3.701 is the correct answer :)

The population of Hermitville increased from 142,340 to 186,480 in the last 5 years. During the same time period, Crabville incr
Musya8 [376]
The rate of increase of population of Hermitville is given by:
PR=(Present Population-Past Population)/(Past population)*100
PR=(186480-142340)/142340×100
PR=31.01%
The population increase in Hermitville is 31.01;
This implies that it's population growth is faster than that of Crabville by a factor of
31.01/26=1.19.
The answer is B
