PLS HELP I WILL GIVE BRAINIEST If triangle BCD were rotated over the y-axis from point (0, 0), what would be the coordinates of the new triangle's vertices?
A. (0, -1) , (-4, -3), (-2, -1)
B. (-1, 0), (-5, -2), (-3, 4)
C. (1, 0), (5, 2), (3, 0)
D. (1, 0), (1, -2), (-3, -4)
The coordinates of the new triangle's vertices are (0, -1), (-4, -3), and
(-2, -1). Hence option A is true.
Used the rule of a point (x, y) when rotated over the y-axis of 90° clockwise rotation from point (0, 0),
(x, y) → (y, - x)
Given that the triangle BCD is shown in the image.
Here, the coordinates of the vertices of BCD are,
B = (1, 0)
C = (3, - 4)
D = (1, - 2)
Now apply the rotation rule, the coordinates of the new triangle's vertices are;
B' = (0, - 1)
C' = (- 4, - 3)
D' = (- 2, - 1)
Therefore, the option A is true.

Group of answer choices Logistic regression can be used as a classifier by limiting the domain of the logistic function to positive real numbers only. Logistic regression can be used as a classifier by using a threshold on the outcome of the logistic function and using this threshold to classify the inputs. Logistic regression can be used as a classifier by expanding the range of the output of the logistic function. Logistic regression can be used as a classifier by removing the nonlinear relationship between input and output.
Logistics regression can be used as a classifier by Logistic regression can be used as a classifier. The second option is correct.

When rolling a pair of die, what is the probability of rolling the sum of 12 OR less than 5? P(sum of 12 OR <5)
The probability P (sum of 12 OR <5) is 7/36 because the total outcomes are 36.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total outcomes = 36
The probability that the sum is 12:
P(A) = 1/36
The probability that the sum is less than 5:
P(B) = 6/36
The probability:
P(sum of 12 OR <5) = 1/36 + 6/36 = 7/36
Thus, the probability P (sum of 12 OR <5) is 7/36 because the total outcomes are 36.

Read the excerpt from "A Century Ride.” Lizzie Dunlop patted the small lady’s shoulder soothingly. "There, there, little iceberg,” she said, "let it all be buried! It’s forgotten. You shall never be worried about it again. You are here to enjoy every moment of your holiday, and to tell me the news of civilization, and to take rides across the prairie. What a blessing we have a decent road for the velocipede—I beg pardon—bicycle! You must have lots of grit to mount that scary machine; and—oh! Maude! How can you want to be a surgeon? I should die if I saw a man cut up and mangled; but you are a marvel!” Which phrase from the excerpt is most like the modern language used in writing? There, there little iceberg You are here to enjoy every moment You must have lots of grit I should die if I saw a man cut up
The phrase in the excerpt that is most similar to the modern language used in writing is "You are here to enjoy every moment".
What is modern language?It corresponds to a language that is in current use in society, being a term used to differentiate a language that is still used for communication from a language that is not used anymore today, such as Latin.
Therefore, the phrase relates to the values of modern society with regard to the use of words and the message that the author wants to convey to readers.

I'm really struggling with finding the greatest common factor.
could someone please explain in simple terms?
The GCF is 4
The polynomial factors to [tex]4(3x^2+x+5)[/tex]
==========================================================
Further explanation:
Ignore the x terms
We're looking for the GCF of 12, 4 and 20
Factor each to their prime factorization. It might help to do a factor tree, but this is optional.
12 = 2*2*34 = 2*220 = 2*2*5Each factorization involves "2*2", which means 2*2 = 4 is the GCF here.
We can then factor like so
[tex]12x^2 + 4x + 20\\\\4*3x^2 + 4*x + 4*5\\\\4(3x^2 + x + 5)[/tex]
The distributive property pulls out that common 4. We can verify this by distributing the 4 back in, so we get the original expression back again.
The polynomial inside the parenthesis cannot be factored further. Proof of this can be found by looking at the roots and noticing that they aren't rational numbers (use the quadratic formula).

Peter is planting a rectangular garden. The length is 15 yards longer than the width. Jorge is planting a square garden. The sides of Jorge's garden are equal to the width of Peter's garden. What is the ratio of the area of Peter's garden to the area of Jorge's garden? Use this ratio to find the ratio of the areas if the width of Peter's garden is 32 yards.
x + 32/x ; 32/15
x-32/x ; 32/15
x+15/x ; 47/32
x-15/x ; 47/32
If the width of peter's garden is 32 yards, the ratio of the areas is 47: 32
Area of a rectangle.area of rectangle = lw
