Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2
Hope it helped!
Answer: last graph
Step-by-step explanation: Graphs of functions that are ODD, are symmetric about the origin.
Graphs of function that are EVEN, are symmetric about y-axis.
We need to figure out which one of the 4 are EVEN. So we take y-axis as the mirror and see both sides, LEFT and RIGHT and see i the points are symmetric or not.
Graph 1, 2, 3 ---- not symmetric about y-axis
Graph 4 ------- Definitely every point to left side of y-axis has a corresponding mirror point to the right of y-axis. So this is an EVEN FUNCTION.
Answer:
1/8 of a loaf
Step-by-step explanation:
Divide the 1.5 loafs by 12 people
Answer:
solution given:
let's see only in a right-angled triangle Δ ACD.
AC=3 units
AD=5 units
since Δ ACD is a right-angled triangle. It satisfies Pythagoras law
25=9+
=25-9=16
Now
Area of rectangle Δ ACD=
similarly,
since AB=CE=2.4 units
Δ ACE is a right-angled triangle. It satisfies Pythagoras law.
now
area of trapezoid=area ofΔACD+Area of ΔABC
=6+
What is the probablity for the number of times Jada will pull a tile wit a star?
Answer: Number of tiles pulled out of the bag by Jada = 10, so she completed 10 trials.
The outcome of each trial was star, circle or a square.
Step-by-step explanation: We can find the experimental probability of pulling each shape from the bag based on the outcomes of Jada's experiment and number of trial.
- P(Star) = Number of stars/Number of trials= 5/10
- P(Circles)= Number of circles/Number of trials =3/10
- P(Square) = Number of Square/Number of trials = 2/10
Here, P refers to Probability of an outcome
If Jada repeats the experiment, She would likely again pull more stars than circles or square. She may get different number of stars,circles or squares but over a large number of trials, she would expect the ratio of the stars in the proportion. We can use this proportonal relationship to get the reasonable prediction about te number of times she pull different shape tiles.
<u>Number of outcomes(10 trials) </u> = <u>Number of outcomes(100 trials)</u>
Number of trials(10 trials) Number of trials (100 trials)
- Numbeof stars = 5/10 =s/100
5*10/ 10*10 =50/100 - Number of Circle = 3/10 = c/100
3*10/10*10 = 30/100 - Number of square = 2/10 = q/100
2*10/10*10 = 20/100
If she does the experiment 100 times then she should expect to pull out 50 stars tile, 30 circles and 20 Square.
Hence, Jada pulled out the 100 tiles from the bag.
