Answer:

Romeo Whigh is 40m.

Step-by-step explanation:

P=a*b,

a=60m, b=wight(w), P=2400m^2

w=?

Change known size in P=a*b

2400=60*w

w=2400/60

w=40m

The figure is mad up of two shapes? A semicircle and a rectangle

musickatia [10]

Answer:

Your answer choice is correct.

Step-by-step explanation:

The length of the semicircle is ...

s = π·r = π(4 in)

The three sides of the rectangular section total ...

9 in + 8 in + 9 in = 26 in

The sum of these lengths make up the perimeter of the figure:

P = 4π in + 26 in

P = (4π +26) in

Determine the amplitude (A), period (P), and phase shift (PS) of the function f(x)= 3sin(x-4)+9

Tpy6a [65]

ANSWER

D.
$A=3,P=2\pi,PS=(4,9)$

EXPLANATION

The given function is

$f(x) = 3 \sin(x - 4) + 9$

Comparing to the general form of a trigonometric sine function,

$f(x) = A \sin(Bx-C)+D$

$A=3$
The amplitude is absolute value of A

$|A| = |3| = 3$

$B=1$

The period is given by

$p = \frac{2\pi}{ B}$

$p = \frac{2\pi}{ 1} = 2\pi$

$C=4$

is a shift to the right of 4 units.

and

$D=9$

is an upward shift of 9 units

Therefore the phase shift is (4,9).

The correct answer is D

Enter the equation in standard form.<br> y − 6 = −(x + 4)

worty [1.4K]

<h3>Answer: x + y = 2</h3>

====================================================

Work Shown:

y - 6 = -(x + 4)

y - 6 = -x - 4

y = -x - 4 + 6 ..... adding 6 to both sides

y = -x + 2

y + x = 2 .... adding x to both sides

x + y = 2

The equation is in standard form Ax+By = C, with A = 1, B = 1, and C = 2.
