Answer:

Step-by-step explanation:

If a point (x, y) is translated by 4 units horizontally right and 1 unit upwards, coordinates of the image point will be,

(x, y) → (x + 4. y + 1)

Therefore, vertices of the image triangle ABC will be,

A(2, 2) → A'(2+4, 2+1)

           → A'(6, 3)

B(5, -1) → B'(5+4, -1+1)

           → B'(9, 0)

C(1, -2) → C'(1+4, -2+1)

           → C'(5, -1)

Then reflected across y-axis.

Rule for the reflection across y-axis will be,

(x, y) → (-x, y)

A'(6, 3) → A"(-6, 3)

B'(9, 0) → B"(-9, 0)

C'(5, -1) → C"(-5, -1)

Consider the following hypothesis test: : : A sample of provided a sample mean and a sample standard deviation . Enter negative
SSSSS [86.1K]

Answer:

-1.540

Step-by-step explanation:

H0 : μ = 18

H0 : μ ≠ 18

The sample size, n = 48

Sample mean, xbar = 17

Sample standard deviation, s = 4.5

α = 0.05

The test statistic :

(xbar - μ) ÷ (s/√(n))

(17 - 18) ÷ (4.5 / √48))

-1 ÷ 0.6495190

= -1.5396

= -1.540 (3 decimal places ).

An airplane descends 1.5 to an elevation of 5.25 miles. find the elevation of the plane before it descends
s344n2d4d5 [400]
Assuming that the 1.5 is in miles you must add 1.5 to 5.25 because you are looking for the previous elevation of the plane before it descended giving you an answer of 6.75 miles.

Help please !! geometry problems.
Akimi4 [234]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

In each question sum the 3 angles and equate to 180

3

a.

x + 8x + 90 = 180

9x + 90 = 180 ( subtract 90 from both sides )

9x = 90 ( divide both sides by 9 )

x = 10

b

4x - 5 + 3x + 11 + 90 = 180

7x + 96 = 180 ( subtract 96 from both sides )

7x = 84 ( divide both sides by 7 )

x = 12

4.

4x + 2x + 11 + 19 = 180

6x + 30 = 180 ( subtract 30 from both sides )

6x = 150 ( divide both sides by 6 )

x = 25

5.

5x + 20 + 2x - 5 + 3x - 10 = 180

10x + 5 = 180 ( subtract 5 from both sides )

10x = 175 ( divide both sides by 10 )

x = 17.5
