The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given sin 0 = 2/5, find cos 0.
cos O = ✓21/ [ ? ]
Simplify the fraction.
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5

Find the volume of a 1 km3 body of water in m3, and select the correct units.
Answer:
1,000,000,000 [tex]m^3[/tex]
Step-by-step explanation:
1 kilometer is equal to 1000 meters, and 1 [tex]km^3[/tex] is 1 km * 1 km * 1 km
Therefore,
1000m * 1000m * 1000m = 1,000,000,000 [tex]m^3[/tex]

What is the vertex of the graph of the quadratic function f(x) = x2 + 6x +10?
F (3,-1)
G(-3,-1)
H(-3,1)
J(3,1)
Answer:
(-3, 1) (Answer H)
Step-by-step explanation:
f(x) = x^2 + 6x +10 can be rewritten by "completing the square" as
f(x) = (x + 3)^2 + 1, and by comparing this to y = (x - h)^2 + k, we see that h is -3, k is 1, so the vertex, (h, k), is at (-3, 1) (Answer H)

Find the center and radius of this
circle:
(x + 9)2+(y – 6)2= 25
Center = ([ ? ],[])
a
Radius = []
Answer:
Center= (-9,6) Radius=5
Step-by-step explanation:
correct answer:
( x + 9 ) ² + ( y - 6 ) ² = 25
center = ( -9, 6 )
radius = 5
equations:
we know from the given equation that the center would be (-9, 6) because we have to plug into the equation; ( x – h ) ² + ( y – k ) ² = radius²
how to find the center coordinates:
if youre confused on how we got the -9, by using the negative addition rules:
x - (-9) we can simplify that to ( x + 9 ) like shown above so that how we got -9. It's a little easier to find the 6 because its just x - 6 so we dont have to simplify anything its just 6.
how to find the radius:
the radius is a little more difficult to find, but, since we are given 25, we can just type the square root of 25 (√25) which would be 5!
thats it!! hope this helps<3

B. g(x) = - (x + 3)² + 4Step-by-step explanation:
The function is f(x) = x²
Transformation steps
1. Reflection across the x-axis:
x² → -x²2. Translation 3 units to the left:
- x² → - (x + 3)²3. Translation 4 units up:
- (x + 3)² + 4The new function is:
g(x) = - (x + 3)² + 4Correct choice is B
A bus makes a stop at 2:30, letting off 10 people and letting on 8. The bus makes another stop ten minutes later to let off 5 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?
Answer:
7 less people
Step-by-step explanation:
You let 10 people off then you let 8 on meaning there are 2 less people. Then 5 more people get off meaning there are 7 less people
Answer:
7 less people

Answer:
688.7
Step-by-step explanation:
Top and Bottom
Area = 3/4 * pi * r^2
r = 6
Area = 3/4 * 3.14 * 6^2
Area = 84.78
Don't round yet.
Vertical surface
Vertical surface = 3/4 * pi * d * h
d = 12 inches (the diameter)
Vertical surface = 3/4 * 3.14 * 12 * 15
Vertical surface = 423.9
Two inner faces
They are both rectangles
Area = 2 * L * W
L = 15
w=6
Area = 2 * 15 * 6 180
Total 688.68
Total = 688.7
