A rectangle is placed around a semicircle as shown below. The length of the rectangle is 3 cm. Find the area if shaded region. U

love history [14]

Answer:

0.9675sq.cm

Step-by-step explanation:

Find a related diagram attached

Area of the shaded region = Area of rectangle - area of semicircle

Area of rectangle = 3cm * 1.5cm

Area of rectangle = 4.5sq.cm

Given

diameter of the semicircle = 3cm

area = πd²/8

Area of the semicircle = 3.14(3)²/8

Area of the semicircle = 3.5325sq.cm

Area of the shaded region = 4.5 - 3.5325

Area of the shaded region = 0.9675sq.cm

What change(s) should Sylvia make to the equation to find the value of t in the above scenario?

finlep [7]

Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer $P_{0}$ = 4800

Decrease in the population of the deer after every 8 years = $\frac{1}{2}\times (\text{Initial population})$

Decrease in population is an exponential process, so the expression representing population will be,

$P_{t}=P_{0}(1-r)^x$

Where $P_{t}$ is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = $\frac{\text{Number of years}}{8}$

By substituting the values of r and x in the expression,

$P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}$

$P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}$

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by ( $\frac{1}{2}$ ) and $\frac{t}{2}$ should be replaced by $\frac{t}{8}$ .

Option D. will be the answer.

which of the following are right triangles: a triangle with side lenghts 6 inches, 8 inches,10 inches, a triangle with side leng

amid [387]

Answer:

(6, 8, 10) right
(8, 15, 17) right
(5, 12, 13) right

Step-by-step explanation:

It can be helpful to memorize a few of the Pythagorean triples that show up in Algebra problems. Their multiples also form right triangles.

(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)

The triple (6, 8, 10) is the first one of these, multiplied by 2 inches.

The only triple that is a sequence of consecutive integers is (3, 4, 5), so you know immediately that (4, 5, 6) does not form a right triangle.

Of course, you can check any of them to see if the squares of the smaller two numbers total the square of the larger number:

4² +5² = 16 +25 = 41 ≠ 6² . . . . . (4, 5, 6) is not a right triangle
