Answer:

C, D

Step-by-step explanation:

An expansion would make a image bigger. The only way to do that is dilate the image by a scale bigger than 1. Both 2 and 3 are greater than 1.

Answer:

C. 2 and D. 3

Step-by-step explanation:

A value below 1 will result in a contraction of the original figure, while a value equal to 1 will result in the same image. Thus, we need a factor greater than 1. In this problem, option C and option D are greater than 1 being 2 and 3 respectively. Those are your answers.

Find the vertex, focus, and directrix. y = 1/24(x+1)² - 3.

Vedmedyk [2.9K]

$y = \frac{1}{24}(x+1)^2 - 3\\\\y+3 =\frac{1}{24}(x+1)^2\ \ / *24\\\\ (x+1)^2 = 24(y+3)$

This is an equation of a parabola that opens upwards.

$Its \ standard \ form: \\(x-h)^2=4p(y-k)\\ (h,k)=(x,y) \ coordinates \ of \ the \ vertex\\\ (h,k)=(-1,-3) \\\\axis \ of \ symmetry: \ x= -1\\ \\4p=24\ \ /:4\\p=6$

$focus:(h,k+p)=(-1,-3+6)=(-1,3) \\ \\directrix: \ y=k-p=-3-6=-9$

The chances of winning are often written in terms of odds rather than probabilities. The odds of winning is the ratio of the num

Free_Kalibri [48]

Answer:

you should play the game with the probability of winning is one tenth

Step-by-step explanation:

If the probability of winning an instant prize game is one tenth, <u>then the odds in the game can be described as 1:9</u> . The odds are clearly better than the game with odds 1:10.

In other words,

If the odds of winning a instant prize game are 1:10, <u>then the probability of winning the game is one eleventh</u>. This is a lower probability than the game which has the probability of winning one tenth.

the length of a rectangle is 3 cm more than twice its width. Find the largest possible width if the perimeter is at most 66cm

Vanyuwa [196]

If you let the width be x, then the length will be 2x + 3. The perimeter P is twice the width plus twice the length, i.e., P = 2*x + 2*(2x + 3) = 2x + 4x + 6 = 6x + 6. So if the perimeter is 66 cm then 66 = 6x + 6 ---> 6x = 60 ---> x = 10 cm., and so if the perimeter is at most 66 cm., the width can be at most 10 cm..
