Answer:

C(-1)= -5

Step-by-step explanation:

This question asks us to find C(-1). We know what C(x) is, it is:

C(x)=-4x^{2} +4x+3

Therefore, we must substitute -1 in for every x to find C(-1).

C(-1)=-4(-1)^{2} +4(-1)+3

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, evaluate the exponent.

-1^2=-1*-1=1

C(-1)=-4(1) +4(-1)+3

Next, multiply -4 and 1.

C(-1)=-4+4(-1)+3

Multiply 4 and -1 again.

C(-1)=-4+ -4 + 3

Add the numbers together.

C(-1)=-8+3

C(-1)=-5

Hey there! :)

Answer:

C(-1) = -5.

Step-by-step explanation:

C(x) = -4x² + 4x + 3

Plug in -1 for x to solve for C(-1):

C(-1) = -4(-1)² + 4(-1) + 3

Simplify:

C(-1) = -4 + (-4) + 3

C(-1) = -5

Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.
Ivahew [28]
Ok... so this question can be solved by using simultaneous equations. 

Use the general from of a parabola 

y = ax^2 + bx + c

you know the value of c, the y-intercept... y = -4

which means the equation is 

y = ax^2 + bx - 4

now use the other 2 points to get 2 equations in 2 unknowns

(-2, -20) just substitute 

-20 = (-2)^2a + (-2)b - 4  ~~~or~~~ -20 = 4a - 2b - 4

this becomes

4a - 2b = -16

now the other equation using (4, -20)

The simplified form is

Find the value of x.
Ainat [17]

Answer:

\textsf{x=22.5}

Step-by-step explanation:

\textsf{According to intersecting tangent - secant theorem,}

\textsf{x=1/2[(4x+5)-50]}

\textsf{2(x)=4x+5-50}

\textsf{2x=4x-45}

\textsf{2x-4x=-45}

\textsf{-2x=-45}

\textsf{x= -45/-2}

\textsf{x=22.5}
