2 meters is about six feet, the man is missing about 1.5 feet for his shadow. That means the elephant is also missing 1.5 feet. The elephant is 3 meters tall

Jordan has 275.00 in his bank account. The bank will pay Jordan 4% interest per year on the value of his account. If Jordan does

Jordan have $286 in his account after 1 year.

Solution:

Given data:

Principal (P) = $275.00

Rate of interest (R) = 4%

Time (T) = 1 year

Let us first calculate the simple interest.

Simple Interest Formula:

$$\text {S.I}=\frac{\text {PRT}}{100}$

Substitute the given values in the simple interest formula.

$$\text {S.I}=\frac{275\times4\times1}{100}$

$=11$

Simple interest = $11

Calculating the amount in account after 1 year:

Amount = Principle + Simple Interest

= $275.00 + $11

Amount = $286

Hence Jordan have $286 in his account after 1 year.

Use completing the square to solve this quadratic equation.

borishaifa [10]

Step-by-step explanation:

x² + 6x + 9 = 2

(x + 3)² = 2

x + 3 = ±sqrt(2)

x = -3 ± sqrt(2)

so, B and D are correct.

control :

(-3 + sqrt(2))² + 6(-3 + sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) - 18 + 6sqrt(2) + 9 = 2

2 = 2

correct

(-3 - sqrt(2))² + 6(-3 - sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) - 18 - 6sqrt(2) + 9 = 2

2 = 2

correct

(3 + sqrt(2))² + 6(3 + sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) + 18 + 6sqrt(2) + 9 = 2

38 + 12sqrt(2) = 2

wrong.

(3 - sqrt(2))² + 6(3 - sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) + 18 - 6sqrt(2) + 9 = 2

38 - 12sqrt(2) = 2

wrong.
