Answer:

$y=-e^{-3x-c_1}+6$

Step-by-step explanation:

$\frac{dy}{dx}+3y=18\\\\\mathrm{Substitute\quad }\frac{dy}{dx}\mathrm{\:with\:}y'\:\\\\y'\:+3y=18\\\\Rewrite\\\\\frac{1}{6-y}y'\:=3\\\\Solve \::\frac{1}{6-y}y'\:=3\\\\-In(6-y)=3x+c_1\\\\Isolate\:y\\\\\\y=-e^{-3x-c_1}+6$

Answer: $x=4.7434$

Step-by-step explanation:

Use the pythagorean theorem $a^{2} +b^{2} =c^{2}$

plug in and solve

$x^{2} +3x^{2} =(3\sqrt{10}) ^{2}$

$4x^{2} =90$

$x^{2} =22.5$

$x=4.7424$

if you need to solve for the sides

3x = 3(4.7434) = 14.2302

The diagram shows one way to develop the formula for the area of a circle. Pieces of a circle with radius r are rearranged to cr

podryga [215]

Question:

a. A = (2πr)(r)

b. A = (2πr)(2r)

c. $A =\frac{1}{2} (2\pi r)(r)$

d. $A =\frac{1}{2} (2\pi r)(2r)$

Answer:

The correct option is $A =\frac{1}{2} (2\pi r)(r)$

Step-by-step explanation:

The formula for the area, A of a parallelogram = base, b × height, h

Therefore, since the base dimension is approximately half the perimeter of a circle, we have;

Base, b = 2·π·r × 1/2

Where the height of the parallelogram, as shown in the diagram is approximately the radius of the circle, we have;

Height, h = r

Therefore, the approximate area, A of the parallelogram is given by the following relation;

A = b × h = 2·π·r × 1/2 × r Which is the same as A = $\frac{1}{2} (2\pi r)(r)$ .

A golfer needs to know how tall a tree is to chip a ball over the tree onto the green in a golf match. his caddie knows that he

Inga [223]

The height of the trre will be given by:
tan θ=(opposite)/(adjacent)

θ=52°
Adjacent= distance of the golfer to the tree= 10 ft
opposite = height, h, of the tree
thus
tan 52=h/10
hence solving for h we get:
h=10tan52
h=12.799~12.8 ft
