Answer:
Step-by-step explanation:
we can write sin(3x+10)= cos{90-(3x+10)}
now
cosx= cos{90-(3x+10)}
eliminating cos from both sides we get
x=90-3x-10
4x=80
x=20
tan 20=0.364
it can be 40 also if we take the sin part
The statement that is not true about the given trigonometric graph is; Option A: The vertical phase shift of y = 3 sin(-5x - π/2) - 6 is; π/5
<h3>How to Interpret Trigonometric Graphs?</h3>
Let us analyze the options;
A) For the give equation;
y = 3 sin(-5x - π/2) - 6
From the general equation given we can say that;
A = 3
B = 5
C = -π/2
D = -6
Thus, phase shift = C/B = -(π/2)/5
Phase Shift = -π/10.
Thus, option A is not correct.
B) Period = 2π/B
Thus; Period = 2π/5
Formula for frequency from period is;
Frequency = 1/period
Thus, it is correct that Period and frequency vary indirectly
C) As B gets bigger, the period gets smaller and the frequency gets greater. Thus, this option is correct
D) This statement is correct.

Hi!
First, change 900.37, into 900. and 29.8 into 30.
900/30= is 30.
So your estimated answer is 30.
Hoped I helped!
This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.
15.37
× 5
---------
76.85
15.37 times 5 is 76.85
Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85
I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?
