Step-by-step explanation:
Given angles are central angles and the measure of central angles are equal to the measure of the ark they see so the measure of arc BD is equal to angle <A and A is equal to 360 - 150 - 97 (since the sum of these angles equal to 360)
ark BD = 113 and the measure of arc DCB
150 + 97 = 113
Answer:
C) 549 km²
Step-by-step explanation:
The area of the regular pentagon is given by ...
A = (1/2)Pa
where P represents the perimeter, and 'a' represents the apothem (6.2 km). Of course, the perimeter is 5 times the side length.
The lateral area is the product of the perimeter and the height:
LA = Ph
Using these formulas, and recognizing the total area includes two (2) pentagons, we have ...
total area = (LA) +2(A) = Ph +2(1/2)Pa = P(h +a)
= (45 km)(6 km +6.2 km) = 549 km^2
Square root of 11 because:
sqrt2^2 = 2
3^2 = 9
so C^2 or the hypotenuse would be the square root of 11
Answer:
Option: a is correct
a) y= -cos x
Step-by-step explanation:
We could clearly see that the graph of the function passes through a point on the y-axis which is :
(0,-1)
i.e. when x=0 the value of the function y= -1
So we will check in each of the following options by putting x=0 and check whether y= -1 or not.
b)
y=sin x
on putting x=0 we get:
y=sin 0=0≠ -1.
Hence, option b is incorrect.
c)
y= cos x.
we put x=0
y= cos 0=1≠ -1.
Hence, option c) is incorrect.
d)
y= -sin x
we put x=0 to obtain:
y= -sin 0=0≠ -1.
Hence, option d is incorrect.
Hence we are left with option a i.e.
The graph represents the function:
y= -cos x. (Hence, option a is correct)
( Also it satisfies at x=0
since, y= -cos 0= -1 )
