Mathematics
1 answer:
kifflom [539]3 years ago
6 0

Answer:

C. -7x^2 - 28

Step-by-step explanation:

Firstly simplify the bracket before doing anything;

4x(3x - 7) = 12x^2 - 28x

then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;

12x^2 - 28x -19x^2...then group the values with the same exponent of x,

(12x^2 - 19x^2) - 28x

; -7x^2 - 28x

Analyze the end behavior of both functions.
igor_vitrenko [27]

Answer:

The end behaviour of all the functions is same ie they all tend to zero.

Step-by-step explanation:

In every option the function f(x)is a linear function which tends to infinity at the  end(as x tends to infinity).Now the function g(x)in every option is just the reciprocal of f(x).As we all know

\lim_{n \to \infty} f(x)=∞

then

\lim_{n \to \infty} 1/f(x)=0

GEOMETRY HELP! Celeste is constructing the perpendicular bisector of ST⎯⎯⎯⎯⎯ . Which set of instructions explains a correct way
Elan Coil [88]

Answer:

The answer is C.

Step-by-step explanation:

Given the line segment ST. we have to give the instruction to construct the perpendicular bisector of line ST.

So to construct the perpendicular bisector of line our first step is to place the compass at one end of line and then adjust the compass more than half of line segment and draw the arc on each side of segment.

After that Keeping the same compass width, draw arcs from other end of line. Place scale where the arcs intersect, and draw the line segment.

So, the correct match is option C )  Place the compass point on point S and open the compass so that the pencil point is on the segment, but closer to point T than to point S. Draw an arc on each side of segment.

Find x. Round your answer to the nearest tenth of a degree.<br> x
NeTakaya

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = \frac{adjacent}{hypotenuse} = \frac{6}{9} , then

x = cos^{-1} ( \frac{6}{9} ) ≈ 48.2° ( to the nearest tenth )
