Answer: 62.83
Step-by-step explanation:
A = B+32
B = 5C
A = 5C+32
C has d dollars so replace d for c
A = 5d+32
Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13
Answer:
50.24 in.
Step-by-step explanation:
Radius of Big circle ( R ) = 2 + 3 = 5 in.
Radius of Small circle ( r ) = 2 in.
Area ( Shaded region )
= Area ( Big circle - Small circle )
= πR² - πr²
= π ( R² - r² )
= 3.14 ( 5² - 3² )
= 3.14 ( 25 - 9 )
= 3.14 × 16
= 50.24 in.
Answer:
B. y ≤ –3x + 5
Step-by-step explanation:
Its B, all y-values are less than -3x+5. also consider root by setting -3x+5=0
x=5/3 is positive so its the second one

Answer:
Step-by-step explanation:
we know that
The solution of the inequality is the shaded area below the solid line (the gray area)
The slope of the solid line is negative
The y-intercept of the solid line is positive
The equation of the solid line is equal to
therefore
the equation of the inequality is equal to
