Answer:
35.4m below sea level
Step-by-step explanation:
172.5 - 137.1 = 35.4
Answer:
Step-by-step explanation:
To solve this problem you must know the formula of subtraction of angles for the function cosx.
The formula is:
We can write 30° as: 45° - 15°
Then:
Using the formula for subtraction of angles we have:
Notice that we have achieved the expression shown in the statement
Finally:
Answer:
500 points
Step-by-step explanation:
Rocco scored 1/5 as many points as Stephen, so scored ...
(1/5) × (2500 points) = 500 points
Rocco scored 500 points.
Answer:
A) (-5, -34)
Step-by-step explanation:
f(x) = x^2 + 10x - 9
We complete the square to get the equation in vertex form
Take the coefficient of the x term and divide by 2 then square it. We add it and then subtract it not to change the value of the equation
f(x) = x^2 + 10x +(10/2)^2 - (10/2)^2 - 9
f(x) = x^2 +10x +25 -25 -9
f(x) = (x^2 +10x +25) -34
The term in parentheses simplified to (x+10/2) ^2
= (x+5)^2 -34
= (x - -5)^2 -34
This is in the form (x-h)^2 +k
The vertex is (h,k) h=-5 and k=-34
(-5,-34)
Answer:
Commutative
Step-by-step explanation:
Multiplication Property is if AxB=BxA.
Identity would be like 1x7=7
Commutative would be your problem. 5x3=3x5
Zero would be like 0x7=0
Associative would be like (3x5)x2=3x(5x2)
Distributive would be like 7x3=(5x3)+(2x3)
