Answer:
900°
Step-by-step explanation:
What is the sum of the measures of the interior angles of a 7-gon?
The formula to measure the interior angles of a polygon
= (n- 2) × 180 °
Where,
n = number of sides
We are given 7 - gon
This means it has 7 sides = Heptagon
Hence,
The measure of the interior angle is given as:
(7 - 2) × 180°
= 5 × 180°
= 900°
The sum of the interior angles of a 7-gon is 900°

C. +√5/3
D. -√5+3
Answer: Its a
Step-by-step explanation:
The value of [tex]x=3+\sqrt{5}[/tex] make the quadratic equation true.
Quadratic equation :Given equation is,
[tex](x-3)^{2}=5[/tex]
We have to solve above quadratic equation.
Expand above equation first,
[tex](x-3)^{2}=5\\\\x^{2} +9-6x=5\\\\x^{2} -6x+4=0\\\\x=\frac{6\pm \sqrt{36-16} }{2} \\\\x=3\pm\sqrt{5}[/tex]
Thus, the value of [tex]x=3+\sqrt{5}[/tex] make the quadratic equation true.

A. FX) = 2 (7)
O B. FX) = 2
C. F(X) = 2 · (0.5)
D. FX) = 2(16)
To distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.
What is exponential function?The mathematical symbol again for exponential function is e^x. The word, unless specifically stated differently, typically refers to the optimistic functional of a real variable, but it may be extended towards the complex numbers or adapted to other mathematical like matrices and Lie algebras.
The idea of exponentiation, or repeated multiplication, is where the exponential function got its start, but more recent definitions—there are several that are equivalent—allow for it to be rigorously expanded to everyone real arguments, especially irrational values.
A. FX) = 2 (7)→ 6(a+8)
O B. FX) = 2→4(1+ 9x)
C. F(X) = 2 · (0.5)→(9m + 10) x 2
D. FX) = 2(16)→ 3 (2x + 4y - 15z)
Therefore, to distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.
