given the function "x) - 2
x2-81
1 .1 on your graphing calculator, what is the most appropriate viewing window to see the graph?
xmin: -10, xmax: 10
ymin: -10, ymax: 10
xmin: -5, xmax: 5
ymin: -5, ymax: 5
xmin: 0, xmax: 10
ymin: 0. ymax: 10
xmin: -10, xmax: 0
ymin: -10, ymax: 0

i belive those are the ones that are under 90 degreese.

the answer is 24

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
