To indicate a rightward shift of 7 units, subtract 7 from the argument, resulting in f(x-7)

To indicate an upward shift of 5 units, add 5 to the function, giving f(x) + 5

Thus, g(x) = f(x-7) + 5 = (x-7)^2 + 5

By subtracting 7 from the function argument, the shift to the right is 7 units.

Adding 5 units to function f results in the graph moving 5 units upward.

Answer:

To signify a rightward translation of 7 units, we adjust the argument by subtracting 7, leading to f(x-7)

For a vertical translation of 5 units upwards, we increase the function by 5, resulting in f(x) + 5

Therefore, g(x) = f(x-7) + 5 = (x-7)^2 + 5

This adjustment of 7 units in the function's argument shifts it rightward by 7 units.

Increasing function f by 5 units raises the graph by 5 units.

An angle bisector always creates two acute angles. find a counterexample to show that the conjecture is false.
Inessa [12570]
An acute angle measures under 90°. An angle bisector is a ray that divides an angle into two equal neighboring angles. For example, if you have an angle of 270°, which exceeds a semicircle, it divides into two angles of 135° each. In this instance, the resulting angles are not acute; rather, they are obtuse.

Which shows the image of ΔRST after the rotation (x, y) → (y, –x)? On a coordinate plane, a triangle has points R (negative 2, 1
PIT_PIT [12445]

Answer:

On a coordinate grid, a triangle is defined by the points R' (1, 2), S' (3, -1), T' (7, 1)

Step-by-step explanation:

We can interpret the coordinates of the triangle's vertices as...

R(-2, 1), S(1, 3), T(-1, 7)

Applying the transformation (x, y) ⇒ (y, -x), these coordinates change to...

R'(1, 2), S'(3, -1), T'(7, 1) . . . . . (this corresponds to the first option)

Triangle QRS is a right triangle with the right angle at vertex R. The sum of m∠Q and m∠S must be equal to 45°. greater than 45°
AnnZ [12381]

Answer:

     The angles m∠Q and m∠S together equal 90°

Step-by-step explanation:

A right angle measures 90°.

The total measure of angles in a triangle sums to 180°.

This gives us:

m∠Q + m∠S + ∠R = 180°

m∠Q + m∠S + 90° = 180°

Rearranging yields:

m∠Q + m∠S = 180° - 90°

m∠Q + m∠S = 90°

The heights of 1000 students are approximately normally distributed with a mean of 174.5 centimeters and a standard deviation of
PIT_PIT [12445]
A. Mean and standard deviation.

The sampling distribution’s mean closely matches the population mean. Since the population mean is 174.5, the sampling distribution’s mean equals this value.

The standard deviation of the sampling distribution is:

            σₓ̄ = σ / √n

Plugging in values:

            σₓ̄ = 6.9 / √25 = 1.38

b. Calculate z-scores for both values:
         
      z = (value - mean) / standard deviation

For 172.5:
     z = (172.5 - 174.5) / 1.38 = -1.49
Corresponding probability ≈ 0.068

For 175.8:
   z = (175.8 - 174.5) / 1.38 = 0.94
Corresponding probability ≈ 0.83

The difference between these probabilities is 0.762.

Approximately 0.762 × 200 = 152 sample means lie between 172.5 and 175.8.

c. Z-score for 172 cm:

    z = (172 - 174.5) / 1.38 = -1.81
Probability ≈ 0.03

Hence, samples with means below 172 cm equal 0.03 × 200 = 6.
