Rotate angle ABC 90 degrees clockwise about the origin and then reflect over the x-axis

Mathematics

Rotation and reflection are instances of transformation

See attachment for the new position of  \triangle ABC

From the question, we have:

A = (-1,1)

C = (-2,4)

The rule of 90 degrees clockwise rotation is:

(x,y) \to (y,-x)

Using the above transformation, the new points would be

A' = (1,1)

B' =(3,3)

C' = (4,2)

The next transformation is reflection over the x-axis

The rule of this transformation is:

(x,y) \to (x,-y)

So, the new points would be:

A" = (1,-1)

B" = (3,-3)

C" = (4,-2)

See attachment for the new points

X cubed = 64/27 A= ±8/3 B= 8/3 C= ±4/3 D= 4/3
Digiron [165]

Answer:

D

Step-by-step explanation:

x³ = 64/27

Take the cube root of both sides.

x = ∛(64/27)

Distribute the cube root to the numerator and denominator.

x = (∛64)/(∛27)

Take the cube root of the terms.

x = 4/3

For a medical study, a researcher wishes to select people in the middle 60% of the population based on blood pressure.
Finger [1]

Answer:

Lower limit: 113.28

Upper limit: 126.72

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 120, \sigma = 8

Middle 60%

So it goes from X when Z has a pvalue of 0.5 - 0.6/2 = 0.2 to X when Z has a pvalue of 0.5 + 0.6/2 = 0.8

Lower limit

X when Z has a pvalue of 0.20. So X when Z = -0.84

Z = \frac{X - \mu}{\sigma}

-0.84 = \frac{X - 120}{8}

X - 120 = -0.84*8

X = 113.28

Upper limit

X when Z has a pvalue of 0.80. So X when Z = 0.84

Z = \frac{X - \mu}{\sigma}

0.84 = \frac{X - 120}{8}

X - 120 = 0.84*8

X = 126.72

The expression, involving exponents , to represent the shaded area, in square inches, diagram. Then use that expression to calcu
mart [117]

Answer:

The shaded area is 23\ in^{2}

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

so

A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})\\ \\A=(2^{2})(3^{2}) -(3^{2} +2^{2})

Calculate the shaded area

Remember that

3^{2}=9\\ 2^{2}=4

substitute

A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}
