If a translation maps point (3, 2) to (4, 5); or T : (3, 2) (4, 5), indicate the image for (2, 4).

Answers

Answer 1

Answer: A translation :
T : ( 3 , 2 ) → ( 4, 5 )
T : ( x, y ) → ( x + 1, y + 3 )
2 + 1 = 3
4 + 3 = 7
Answer:
The image for ( 2, 4 ) is ( 3, 7 ).

If x = 45 has a percentile rank of 75%, which of the following is true? a) The data is positively skewed b) The data is normally distributed c) 75% of the data is less than 45 d) 75% of the data is greater than 45

Answers

Answer:

The correct answer is: c) 75% of the data is less than 45

Step-by-step explanation:

x = 45 has a percentile rank of 75%, Percentile rank represents the percentage of data points that fall below a given value. In this case, 75% of the data falls below the value of 45. This means that 45 is greater than 75% of the data points. Options a) and b) can be ruled out because the given information does not provide any indication about the skewness or distribution of the data. Option d) is incorrect because the percentile rank of 75% indicates that 75% of the data is less than the given value (in this case, 45), not greater.

PLEASE HELP!Find the domain, period, range, and amplitude of the cosine function.

y = -6 cos 4x

A. domain = -1/2 ≤ x ≤ 1/2; period = 6; range:- -6 ≤ y ≤ 6; amplitude = 1/2
B. domain = all real numbers; period = π/2 ; range:- -6 ≤ y ≤ 6; amplitude = 6
C. domain = all real numbers; period = π/2 ; range: -6 ≤ y ≤ 6; amplitude = -6
D. domain = -1/2 ≤ x ≤ 1/2; period = 6π; range: -6 ≤ y ≤ 6 ; amplitude = 1/2

Answers

Domain is all real numbers because there is a y value for every x.
The amplitude is the absolute value of the constant of the outside: |-6| = 6
The range is that x is between the positive and negative amplitude: -6 ≤ y ≤ 6
The period is usually 2π, but here it is 2π/4, or π/2, as it goes up and down 4 times as fast as it would if it was just cos x.

According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 9x4 – 2x2 – 3x + 4?

Answers

The coefficients of x4 is 9. It has factors of 1, 3, and 9. The constant is 4. It has factors of 1, 2, and 4.
The (positive and negative) ratios of the factors of the coefficient of the x4 and the constant 4 are the potential rational roots of the function.
The answers are:
1, -1, 3, -3, 9, -9, 1/2, -1/2, 3/2, -3/2, 3/4, -3/4, 9/2, -9/2, 9/4, -9/4

Answer:

It's B.
