Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.

This question is kinda confusing I need help

Answer:

D) p³ + 2; when p = 3 the number of plants is 29.

Step-by-step explanation:

Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.

So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.

p³ + 2 = n

3³ + 2 = n

27 + 2 = n

29 = n

There are 29 total plants.

The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.

Good luck ^^

Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.
shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a)  The probability that exactly 21 of those surveyed feel the state of morals is poor is

P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519

(b)  The probability that no more than 22 of those surveyed feel that state of morals is poor is

=P(X

(c)  The probability that more than22 of those surveyed feel the state of morals is poor is

P(X>22)\\=1-0.9811\\=0.0119

(d)  The probability that 15 or 16 believe the state of morals is poor is

=P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507

Write the equation of the parabola in vertex form.
BigorU [14]
F(x) = 5(x - 3) + 1

Find slope by using the vertex point and the other point given. You get 5. Then the vertex point is just the opposite x and the number after the parentheses.

If 5x+15y=45 then 6x-18y=?
vovangra [49]
So we have 5x+15y=45
simplify and undistribute 5 from both sides
5(x+3y)=5(9)
divide both sides by 5
x+3y=9
multiply both sides by 6
6x+18y=54

if it was 6x+18y then the answer is 54
if it was 6x-18y, then I don't know the answer
