Pythagoras’ Theorem = a^2+b^2=c^2

c^2= 5^2+12^2
=25+144
=169

c= sqrt of 169
c=13

How can I solve 4x^2 + 12x > -x -3

Damm [24]

He have the following:

$4x^2+12x>-x-3$

solving:

$\begin{gathered} 4x^2+12x+x+3>-x-3+x+3 \\ 4x^2+13x+3>0 \\ \text{factoring} \\ (4x+1)(x+3)>0 \\ (4x+1)>0\rightarrow4x+1-1>-1\rightarrow\frac{4x}{4}>-\frac{1}{4}\rightarrow x>-\frac{1}{4} \\ (x+3)$

Write the explicit formula for the geometric sequence.

My name is Ann [436]

Answer:

Step-by-step explanation:

the n th term ( explicit formula ) of a geometric sequence is

• $a_{n}$ = $a_{1}$ $(r)^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here r = $\frac{8}{16}$ = $\frac{16}{32}$ = $\frac{1}{2}$ and $a_{1}$ = 64, hence

$a_{n}$ = 64 $(0.5)^{n-1}$ → D

Answer:

c) 110°

Step-by-step explanation:

Arc FP is twice the measure of the marked angle, so is 70°. If FD is supposed to be a diameter, then arc FPD is a semicircle (180°) and arc PD is 180° -70° = 110°.
