Answer:

152 degrees

Step-by-step explanation:

CF is a straight line, which means it equals 180 degrees.  But FXE is an angle of  28 degrees so you subtract 180 from 28 to get 152 degrees.

astraxan [27]

Answer:

The answer is two seconds

Step-by-step explanation:

Set the y to 0 as we are looking for the height when f(t) has hit the ground. Then factor and the two zeros of the function are -2 and 2. because the -2 is an answer that that cannot make sense for time in a real world scenario, the answer is the positive zero, or two. :-)

The function p(x) is an odd degree polynomial with a negative leading coefficient. If q(x) = x3 + 5x2 - 9x - 45, which statement
saul85 [17]

Answer:

As x approaches negative infinity, p(x) approaches positive infinity and q(x) approaches negative infinity.

Step-by-step explanation:

The order of the polynomial and the sign of the leading coefficient will let us find the correct answer easily,

If you get a negative number (such as negative infinity) and you take it to an odd power, (for example 3), you will still get a negative number.

As q(x) has a positive leading coefficient, this means that as x approaches negative infinity, q(x)  will approach too negative infinity.

Since p(x) has an odd degree, but negative leading coefficient,

(-)*(-) = +

And this means that p(x) approaches positive infinity

In the 2009 to 2010 school year in country a there were 127,004 in students from country B. This number is 24% more than the num
adoni [48]
If x represents the number of students from country C.

then 122% of x = 116,000

122/100 * x = 116000

Transposing the formula for x;

therefore x = 116000 * 100/122 = 95,082 students

Shaded area=40<br> Find x <br> Width=3x<br> Length=4x<br> Not shaded area=2x
Mashutka [201]
In the process of laying out the question, you have given us important facts about the shaded area and the unshaded area. Now step back for just a second. If they're that deeply involved in the question, do you honestly expect that anybody can answer the question without seeing the picture of them ? ! ?
