Given the following functions, evaluate f×g(7)

lidiya [134]

evaluate g(7) by substituting x = 7 into g(x

g(7) = (49-35-10)/2 = 4/2 = 2

now substitute x = 2 into f(x)

f(2) = √(4 - 48 + 144) = √0 = 0

(f ￮ g)(7) = 0

Lim 1 + cos TX<br>5.<br>x>1 tanưrex

Brums [2.3K]

Answer: 1/2

$\lim_{x \to 1}\frac{1+cos \pi x}{tan^{2}\pi x }\\\\ = \lim_{x \to 1} \frac{1+cos\pi x}{\frac{sin^{2}\pi x }{cos^{2}\pi x } } \\\\\\= \lim_{x \to 1}\frac{cos^{2}\pi x(1+cos\pi x) }{sin^{2}\pi x } \\\\\\= \lim_{x \to 1} \frac{cos^{2}\pi x(1+cos\pi x)}{1-cos^{2}\pi x } \\\\= \lim_{x \to 1} \frac{cos^{2}\pi x }{1-cos\pi x} \\\\= \lim_{x \to 1}\frac{cos^{2}\pi .1 }{1-cos\pi .1}\\\\= \lim_{x \to 1}\frac{1}{1-(-1)}\\\\=\frac{1}{2}$

Write the equation of the line that goes through (-4,13) and (8,49).

algol [13]

Answer:

y=3x +25

Step-by-step explanation:

First calculate the slope:

m = (y1 - y2)/(x1-x2)

m = (49 - 13)/(8-(-4))

m= 36/12 = 3

so we have

y = 3x + b

subtitute a point:

49=3(8) + b

b=25

the equation is y=3x +25
