Answer:

Baltimore is the most populous city in the state of Maryland. The city is located in the center of the state, next to the Patapsco River, which empties into the Chesapeake Bay.

Baltimore has a humid subtropical climate, according to the climatic classification of Köppen.

July is the hottest month of the year, with an average of maximum temperatures of 91 ° F and 73 ° F of average low temperatures. The summers are very humid in the Baltimore area. The maximum temperatures registered were of 107 ° F in 1985. On the other hand, January is the coldest month, with average temperatures of 44 ° F maximum and 30 ° F of minimum temperatures. However, winters may present gusts of warm winds that soften temperatures to the point of enjoying spring periods and Arctic winds cause the collapse of temperatures, especially at night. The lowest temperature registered in Baltimore was -7 ° F, in 1934 and 1984. Due to the heat island effect in the city and a moderate effect of the Chesapeake Bay, the external and internal parts of the Baltimore metropolitan area are usually colder than the city itself and the coastal cities.

The average high temperature of Baltimore in each month is:

-January: 44º F

-February: 47º F

-March: 57º F

-April: 68º F

-May: 77º F

-June: 86º F

-July: 91º F

-August: 88º F

-September: 81º F

-October: 70º F

-November: 59º F

-December: 49º F

A square has a perimeter of 40 m what is the length of each side

zubka84 [21]

Answer:

10m

Step-by-step explanation:

<u>Perimeter</u> means adding up all of the sides of a shape.

One property of a square is that <u>all lengths of a square are the same</u>.

We also know squares have <u>4 sides</u>.

<u />

Lets set up an expression to solve the length for each side with variable S representing the length of a side:

4 * S = 40

Divide each side by 4:

S = 10

Therefore, each side of the square has a length 10m

Let $f(x) = 2x^2 + 3x - 9,$ $g(x) = 5x + 11,$ and $h(x) = -3x^2 + 1.$ Find $f(x) - g(x) + h(x).$

Viefleur [7K]

QUESTION 1

Given that:

$f(x)=2x^2+3x-9$ ,

$g(x)=5x+11$ ,

and

$h(x)=-3x^2+1$

Then;

$f(x)-g(x)+h(x)=2x^2+3x-9-(5x+11)+(-3x^2+1)$

$f(x)-g(x)+h(x)=2x^2+3x-9-5x-11-3x^2+1$

Group similar terms;

$f(x)-g(x)+h(x)=2x^2-3x^2+3x-5x-11-9+1$

Simplify;

$f(x)-g(x)+h(x)=-x^2-2x-19$

QUESTION 2

Given that;

$f(x)=4x-7$ .

$g(x)=(x+1)^2$

and

$s(x)=f(x)+g(x)$

Substitute the functions;

$s(x)=4x-7+(x+1)^2$

Substitute x=3

$s(3)=4(3)-7+(3+1)^2$

$s(3)=12-7+(4)^2$

$s(3)=5+16$

$s(3)=21$

QUESTION 3

Given:

$f(x)=3x+2$

$g(x)=x^2-5x-1$

$f(g(x))=f(x^2-5x-1)$

This implies that;

$f(g(x))=3(x^2-5x-1)+2$

Expand the parenthesis;

$f(g(x))=3x^2-15x-3+2$

$f(g(x))=3x^2-15x-1$

QUESTION 4

The given function is;

$f(x)=3(x-6)^2+1$

Let

$y=3(x-6)^2+1$

$\Rightarrow y-1=3(x-6)^2$

$\Rightarrow \frac{y-1}{3}=(x-6)^2$

$\Rightarrow \sqrt{\frac{y-1}{3}}=x-6$

$\Rightarrow x=6+\sqrt{\frac{y-1}{3}}$

The range is:

$\frac{y-1}{3}\ge0$

$y-1\ge0$

$y\ge1$

The interval notation is;

$[1,+\infty)$
