Answer:
Option D.
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
or
The y-intercept is the value of the function (output) when the value of x=0
In this problem
The output of the function P for x=0 is equal to 5
The output of the function Q for x=0 is equal to 4
therefore
The functions will have different outputs when x=0
The correct question is
A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is going to be circular with a radius of 4x. Once the fountain is built, what will be the area of the remaining yard?
Step 1
find the area of rectangular yard (A1)
A1=(10*x)*15*x=150*x² units²
Step 2
find the area of the circular <span>fountain (A2)
A2=pi*r</span>²---------> pi*(4x)²=16*pi*x²
Step 3
find <span> the area of the remaining yard (A3)
A3=A1-A2----------> 150*x</span>²-16*pi*x²----> x²*[150-16*pi]----> 2*x²*[75-8*pi]
the answer is the option A)
<span> 2x</span>²<span> (75-8pi )</span>
Answer:
B = (-11, -17)
C = (11, -17)
Step-by-step explanation:
Reflection over the x-axis is accomplished by changing the sign of the y-coordinate:
(x, y) ⇒ (x, -y) . . . . . reflection over x-axis
Reflection over the y-axis is accomplished by changing the sign of the x-coordinate:
(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis
__
B = (-11, -17)
C = (11, -17)
__
<em>Check</em>
Reflection over both axes negates both coordinates. It is equivalent to reflection over the origin, or rotation 180°.
A(-11, 17) ⇒ C(11, -17) . . . . . both coordinates change sign
Answer:
4A=5.1 per million 4B=3.8 years
Step-by-step explanation:
4A. A=0.2^2+.01t+5.1 the current level would be 5.1
4B. 8=.2t^2+.01+5.1 minus 8 .2t^2+.01-2.9
t=(-1.0+squ.0001-41-.58)/.4
t=(-.01+squ2.3201)/.4
t=3.78 t+3.78=0 =-3.78
t=-3.83 t-3.83=0 =3.83
Answer 3.83 years
Answer:
lol if a = 90 then b = 75 so C is 105
then you get the derivative number which is X by adding a2 b2 then dividing by the c2. so its true
