DEF is a dilation image of ABC. What is the scale factor?

Mathematics

horsena [70]2 years ago

Answer:

Option (2)

Step-by-step explanation:

ΔDEF is a dilation image of ΔABC.

Rule for the dilation,

Scale factor = \frac{\text{Length of one side of the image triangle}}{\text{Length of one side of the original triangle}}

                    = \frac{DE}{AB}

                    = \frac{4}{8}

                    = \frac{1}{2}

Therefore, scale factor by which ΔABC is dilated is \frac{1}{2}.

Option (2) will be the correct option.

(7 - 3t) + 3(-2t + 5)
katrin2010 [14]

Answer:

22-9t

Step-by-step explanation:

(7 - 3t) + 3(-2t + 5)

=

7+−3t+(3)(−2t)+(3)(5)=

7+−3t+−6t+15

=

Now you need to combine like terms.

7+−3t+−6t+15

=

(−3t+−6t)+(7+15)=

-9t+22=

22-9t

There you go.

Suppose a basketball team had a season of games with the following characteristics:
Masteriza [31]

Answer:

Hello Sir/ Mam

YOUR REQUIRED ANSWER IS 18.6%

Variables defined in the question:

H - Home - Games

W - Winning Games

Now, given:

P(H0.62 PW)0.22

P(W\mid H)=0.30

Required : Of all the games, percentage of games that were at home wins.

Hence, required :

P(W\cap H)

Now, we know that:

P(W\mid H)=\frac{P(W\cap H)}{P(H)}

0.3=\frac{P(W\cap H)}{0.62}

Hence,

P(W\cap H)=0.3*0.62=0.186=18.6\%

I hope this solves your doubt.

Feel free to comment if you still have any query.

Do give a thumbs up if you find this helpful.

The position s(t) of a robot moving along a track at time t is given by s(t)=9t^2−90t+4.
Xelga [282]

The total distance traveled by the robot from t=0 to t=9 is 1422 units

Integration is a way in which smaller components are brought together in pieces to form a whole. Integration can be used in finding areas, volumes and so on.

Given that the position s(t) at any time t is given by the function:

s(t)=9t²−90t+4

The total distance traveled by the robot from t=0 to t=9 can be gotten by integrating the position function within the limits 0< t < 9

Therefore:

Total\ distance = \int\limits^9_0 {s(t) \, dt \\\\Total\ distance = \int\limits^9_0 {(9t^2-90t+4) \, dt\\\\Total\ distance = [3t^3-45t+4t]_0^9\\\\Total\ distance=-1422\ units

The total distance is 1422 units
