The top one is 290° since a circle is 360° and you take away 70° from that you get 290

the second one is 93-25=68 and then 68÷2=34 so 34°

Factor (z-5) (z+4)=52

stich3 [128]

Answer:

$\large\boxed{(z-9)(z+8)=0\to z=9,\ z=-8}$

Step-by-step explanation:

$(z-5)(z+4)=52\qquad\text{use FOIL}:\ (a+b)(c+d)=ac+ad+bc+bd\\\\(z)(z)+(z)(4)+(-5)(z)+(-5)(4)=52\\\\z^2+4z-5z-20=52\qquad\text{subtract 52 from both sides}\\\\z^2-z-72=0\\\\z^2-9z+8z-72=0\\\\z(z-9)+8(z-9)=0\\\\(z-9)(z+8)=0\iff z-9=0\ \vee\ z+8=0\\\\z=9\ \vee\ z=-8$

What is the value of S4 for

zzz [600]

Answer:

90

Step-by-step explanation:

To find s4 we find sum of values when n=1,n=2,n=3,n=4

given expression is $6(2)^{n-1}$

n=1 , plug in 1 for n

$6(2)^{1-1}=6$

n=2

$6(2)^{2-1}=12$

n=3

$6(2)^{3-1}=24$

n=4

$6(2)^{4-1}=48$

Sum of all 4 terms = 6+12+24+48=90

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing? (–6.5, ∞) (–5, ∞) (–∞, –5) (–∞, –6.5)

ryzh [129]

Answer:

Increasing in the interval $(-2.5,\infity)$

Step-by-step explanation:

We have been given a function:

$f(x)=x^2+5x+6$

Please look at the attachment to see the increasing interval of the graph

We can see that the graph is increasing in the interval $(-2.5,\infty)$

The options given in the question are not correct because graph is not increasing in any of these intervals.
