Translation of 2 units left, and a reflection across the x axis :)
monitta3 years ago
3 0

Answer:

The original triangle translated 2 units to the left and then reflected across x-axis.

Step-by-step explanation:

The co-ordinates of ΔABC are:

A = (8, 8)

B = (10, 4)

C = (2, 6)

The co-ordinates of ΔA'B'C' are:

A' = (6, -8)

B' = (8, -4)

C' = (0, -6)

Comparing both the co-ordinates we can see that y co-ordinate values signs have changed and x co-ordinate values are reduced by 2 units.

Thus, we can say that first translation to 2 units left occurred and then reflection around x axis occurred.

calculate the area of the shaded region in each figure. use 3.14 for π and round to the nearest 10th if nessary​
telo118 [61]

Answer:

7.6 cm²

Step-by-step explanation:

Area of rectangle= l x w

3 x 4 = 12 cm

Area of circle= πr²

π x 2.5²= 19.625

Area of shaded= Area of circle - area of rec

19.625- 12= 7.625 cm²

≈7.6

What is x? <br><br> Thank you
zepelin [54]

Answer:

None of those answers are correct

Step-by-step explanation:

There are no real solutions

Let's solve your equation step-by-step.

2+2x−3

2x+3

=

3x+4

x+2

Step 1: Cross-multiply.

2+2x−3

2x+3

=

3x+4

x+2

(2+2x−3)*(x+2)=(3x+4)*(2x+3)

2x2+3x−2=6x2+17x+12

Step 2: Subtract 6x^2+17x+12 from both sides.

2x2+3x−2−(6x2+17x+12)=6x2+17x+12−(6x2+17x+12)

−4x2−14x−14=0

For this equation: a=-4, b=-14, c=-14

−4x2+−14x+−14=0

Step 3: Use quadratic formula with a=-4, b=-14, c=-14.

x=

−b±√b2−4ac

2a

x=

−(−14)±√(−14)2−4(−4)(−14)

2(−4)

x=

14±√−28

−8

Answer:

No real solutions.

The heights of South African men are Normally distributed with a mean of 69 inches and a standard deviation of 4 inches. What is
vekshin1

Answer:

the probability that a randomly selected South African man is taller than 72 inches is 0.2266

Step-by-step explanation:

The heights of South African men are Normally distributed with a mean of 69 inches and a standard deviation of 4 inches

population mean(m) = 69 inches

population standard deviation(s) = 4 inches

Therefore, the number of standard deviation above mean (z score) = (x - m)/s

In this case, x = 72 inches

z score = (72 - 69)/4 = 3/4 = 0.75

Probability that a randomly selected South African man is taller than 72 inches  P(x>72) = 1 - P(x<72) = 1 - z(0.75) using the z table,

P(x>72) = 1 - 0.77337 = 0.2266

therefore, the probability that a randomly selected South African man is taller than 72 inches is 0.2266
