Explanation:

tan(arctan x) = x

This is because arctan is the reciprocal of tan. You can view this as the same as 5(1/5x) = x. Since they are reciprocals, when they are multiplied by each other, they cancel each other out.

Given that f(x) = 2x + 5 and g(x) = x − 7

f(g(x)) = 2(x − 7) + 5
f(g(x)) = 2x - 14 + 5
f(g(x)) = 2x - 9

when x = −3 , f(g(-3)) = 2(-3) - 9 = - 6 - 9 = -15

Find the value of x help 10 points

MrRissso [65]

Answer:

x = 5.67

Step-by-step explanation:

We are given a right angled triangle with a length of the hypotenuse 8 with the remaining two sides (base and perpendicular) that are equal to each other.

Assuming the two equal legs of this right angled triangle to be x, we can use the Pythagoras Theorem to find the value of x.

$(x)^2+(x)^2=(8)^2$

$2x^2=64$

Taking square root at both the sides to get:

$\sqrt{2x^2} =\sqrt{64}$

$1.41x=8\\\\x=5.67$

Therefore, x = 5.67.
