Answer:
The value of x is 90°
Step-by-step explanation:
Given as :
The Trigonometrical equation as :
sin² x - 2 sin x + 1 = 0
Now, Let Sin x= a
So, The equation can be written as :
a² - 2 a + 1 = 0
<u>applying mid-term break</u>
a² - a - a + 1 = 0
Or, a ( a - 1) - 1 (a - 1) = 0
Or, (a -1) (a-1) = 0
∴ a - 1 = 0
i.e a = 1
Now, put the value of a
∵ Sin x = a
So, Sin x = 1
∴ x =
Or, x = 90°
So, The value of x = 90°
Hence, The value of x is 90° Answer
ANSWER
P(X=4 or X=1)=0.20
EXPLANATION
From the probability distribution table,
p(X=4)=0.15
p(X=1)=0.05
We want to find the value of
P(X=4 or X=1).
Recall that:
P(X=4 or X=1)=P(X=4)+P(X=1)
P(X=4 or X=1)=P(X=4)+P(X=1)
We substitute the probability values;
P(X=4 or X=1)=0.15+0.05
P(X=4 or X=1)=0.20
Five thousand two hundred fourteen thousanths
Answer:
MR is 20 because if the side lengths that are shown are congruent, then the bottoms are too. so each part of the bottom that has a number, that number repeats on the part that's part of that triangle. so the bottom lengths go " 4 6 6 4" and you add those together and get 20
The value after 20 years is $ 723.514
<em><u>Solution:</u></em>
<em><u>Formula for Amount compounded annually is as follows:
</u></em>
Where,
"A" is the total amount
"p" is the principal sum
"r" is the rate of interest
"n" is the number of years
From given question,
p = $ 300
r = 4.5 %
n = 20 years
Substituting the values we get,
Thus value after 20 years is $ 723.514
