Answer:

The surface area is 40

Step-by-step explanation:

It is 40 because you have to find the area of each face so you would do 3*4 which equals 12 and since there is 4 of the triangles you do 12*4 which is 48 but when it's a triangle you have to cut it in half so it would really be 24.

Then for the square on the bottom you would do 4*4 which is 16 and then you would add the totals to get 40.

A student draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-

faust18 [17]

Answer:

The positive difference between the a values is 0.5

Step-by-step explanation:

we know that

Both parabolas cross the x axis at (-4,0) and (6,0)

The general equation is

$y=a(x+4)(x-6)$

Find the value of a in the first parabola

The y-intercept is (0,-12)

For $x=0, y=-12$

substitute

$y=a(x+4)(x-6)$

$-12=a(0+4)(0-6)$

$-12=a(-24)$

$a=0.5$

Find the value of a in the second parabola

The y-intercept is (0,-24)

For $x=0, y=-24$

substitute

$y=a(x+4)(x-6)$

$-24=a(0+4)(0-6)$

$-24=a(-24)$

$a=1$

Find the positive difference between the a values for the two functions

$1-0.5=0.5$

CAN SOMEONE HELP PLZZZZ ALGEBRA

alekssr [168]

Answer:

Step-by-step explanation:

The remainder theorem says that when you put the integer part of the binomial for the value of x in f(x), you can solve for the remainder.

f(x) = x^3 - 4x + k is divided by (x - 5) means that 5 is put into f(x)

f(5) = x^3 - 4x + k now put 5 into x on the right

f(5) = 5^3 - 4(5) + k

f(5) = 125 - 20 + k = 91

f(5) = 105 + k = 91

105 + k = 91 Subtract 105 from both sides

k = 91 - 105

k = -14
