Answer:

25°C

Step-by-step explanation:

Since the question asks for in degrees Celsius, we look at the purple section (the lower half of the thermometer)

The red line goes right in between 20 and 30 giving us our answer of 25

nata0808 [166]

Answer:

2x-y=8

Step-by-step explanation:

Equation of a line y-y1 =m(x-x1)

Given m=2, x1=7, y1=6

y-6 = 2(x-7)

y-6 = 2x-14

2x-y = 8

At the beginning of a population study, the population of a large city was 1.65 million people. Three years later, the populatio

Answer:

C. 1.8027

Step-by-step explanation:

The exponential population growth model is given by:

$P(t) = P_{0}e^{rt}$

In which P(t) is the population after t years, $P_{0}$ is the initial population and r is the growth rate.

At the beginning of a population study, the population of a large city was 1.65 million people. Three years later, the population was 1.74 million people.

This means that $P_{0} = 1.65, P(3) = 1.74$

Applying this to the equation, we find r. So

$P(t) = P_{0}e^{rt}$

$1.74 = 1.65e^{3r}$

$e^{3r} = \frac{1.74}{1.65}$

$e^{3r} = 1.0545$

Applying ln to both sides

$\ln{e^{3r}} = \ln{1.0545}$

$3r = \ln{1.0545}$

$r = \frac{\ln{1.0545}}{3}$

$r = 0.0177$

$P(t) = 1.65e^{0.0177t}$

What would be the population of the city 5 years after the start of the population study?

This is P(5).

$P(t) = 1.65e^{0.0177t}$

$P(5) = 1.65e^{0.0177*5}$

$P(5) = 1.8027$

So the correct answer is:

C. 1.8027

What is the awnser please

Scilla [17]

The root (zero) of this problem is A., x =5 only.
Substitute f(x)=0

0=x^2 - 10x + 25

Solve for x.

x = 5.
