Answer:

For the answer to the question above, when you carry your jewelry box or your phone 3 floors down

and 2 miles to the left, the angles and side lengths don't change,

and it still looks exactly the same as it did before you picked it up

and moved it.

Translation can't change angles or lengths. And if those don't

change, then the later shape is congruent to the earlier shape.

What is the vertex of y=-2x^2+10x+1 and is it a minimum or maximum

Reika [66]

Answer:

Step-by-step explanation:

it is maximum.

when leading coefficient of x² is negative,

It is downward parabola.

y=-2x²+10x+1

=-2(x²-5x+(-5/2)²-(-5/2)²)+1

=-2(x-5/2)²+2×25/4+1

=-2(x-5/2)²+25/2+1

=-2(x-5/2)²+27/2

maximum value of y is 27/2 and is attained at x=5/2

vertex is (5/2,27/2)

Answer:

Step-by-step explanation:

It is A' because they are corresponding angles, it is the same exact shape it has just been translated to a different area of the graphic plane.

If my answer is incorrect, please notify me and I'll assess what it was that I did wrong.

choli [55]

The exponential equation for the growth is f(x)=57 $e^{0.51x}$ where x is the number of days and the population on 21st march is 2069983.5 of microbes.

Given:

Days population

0 57

1 95

5 700

10 8525

We have to form exponential equation which shows the growth of microbes.

We know that exponential equation which shows the sum is as under:

f(x)=P $e^{rt}$ where r is the rate of growth and x is the number of days, months or years depending on how things grows.

In the question when x=0 population is 57.

f(0)=57

P $e^{0}$ =57

P=57

When x=1, population is 95.

f(1)=95

P $e^{r}$ =95

57 $e^{r}$ =95

57=95/ $e^{r}$ ----1

when x=5,population is 700.

f(5)=700

P $e^{5r}$ =700

57 $e^{5r}$ =700

57=700/ $e^{5r}$ -----2

Equating 1&2

95/ $e^{r}$ =700/ $e^{5r}$

$e^{5x} /e^{x} =700/95$

$e^{5r-r}$ =7.36

$e^{4r}$ =7.36

$(2.7182)^{4r}$ = $(2.7182)^{2}$

equating both sides

4r=2

r=0.5

put the value of t=21 in the exponential equation

f(21)=57 $e^{0.5*21}$

=57 $e^{10.5}$

=57*36315.5

=2069983.5

Hence the population on 21st march is 2069983.5.
