Answer:

A = 112 square feet

Step-by-step explanation:

The perimeter of a rectangular garden is 46 feet.

P = 2(l+b)

46=2(l+b)

23 = (l+b) ....(1)

Let length is l and breadth is b.

The length of the garden is 5 feet less than three times the width.

l = 3b-5 ...(2)

Put equation (2) in equation (1)

23 = (3b-5+b)

23 = 4b - 5

28 = 4b

b = 7 feet

Pu b = 7 in equation (2)

l = 3(7)-5

l = 16feet

Area of a rectangle is given by :

A = lb

A = 16 × 7

= 112 ft²

So, the area of the garden is 112 square feet.

Answer:

C(t) = 25+34.37t

Step-by-step explanation:

It is given that,

The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.

We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.

At t=0, Jonathan pays $25 as joining fee.

Equation will be :

C(t) = Co+kt

Initially, Co = 25

C(t) = 25

At t = 8,

C(8) = 25 + k(8) = 300

8k = 275

k = 34.37

⇒ C(t) = 25+34.37t

Hence, this is the required equation.

Answer:

216[tex]\pi[/tex]

Step-by-step explanation:

Given the figure.

And the perimeter in the ratio 4: 2: 1.

Perimeter of smallest circle = [tex]8\pi[/tex]

To find:

Area of shaded region.

Solution:

To find the area, we need to have radius first.

And radius can be calculated by the given perimeter.

Formula for Perimeter is given as:

Perimeter = [tex]2\pi r[/tex]

[tex]8\pi = 2\pi r\\\Rightarrow r = 4\ cm[/tex]

Radius of smallest circle = 4 cm

Ratio of perimeter is equal to the ratio of the radii.

Radius of 2nd smallest circle by the given ratio = 8 cm

Radius of largest circle = 16 cm

Area of a circle is given the formula:

[tex]A = \pi r^2[/tex]

Area of the smallest circle = [tex]\pi 4^2 = 16\pi\ cm^2[/tex]

Area of the 2nd smallest circle = [tex]\pi 8^2 = 64\pi\ cm^2[/tex]

Area of the largest circle = [tex]\pi 16^2 = 256\pi\ cm^2[/tex]

Area of the shaded region = Area of largest circle + 2 [tex]\times[/tex] Area of 2nd smallest circle + 3 [tex]\times[/tex] Area of smallest circle - 2 [tex]\times[/tex] Area of smallest circle - 3 [tex]\times[/tex] Area of 2nd smallest circle

Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = [tex]256\pi - 64\pi +16\pi = 216\pi[/tex]

Step 2: Evaluate

Answer:

Step-by-step explanation:

Equation in which to find the slope:

(slope) [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (9 , -4)\\(x_2 , y_2) = (9 , 5)[/tex]

Plug in the corresponding numbers to the corresponding variables:

[tex]m = \frac{5 - (-4)}{9 - 9}[/tex]

Simplify. First solve the numerator and denominators, then divide:

[tex]m = \frac{5 - (-4)}{ 9 - 9} \\m = \frac{5 + 4}{9 - 9} \\m = \frac{9}{0}[/tex]

Because a fraction cannot be out of 0, your answer will be .

Answer:

The area of the rectangle VWXY is 52 square units

Step-by-step explanation:

The formula of the area of the rectangle is A = L × W, where

From the given figure

∵ VWXY is a rectangle

∵ V = (3, -9) and W = (-1, -9)

∵ X = (-1, 4) and Y = (3, 4)

∵ Its length is WX or VY

∴ WX = VY

∵ Its width is VW or XY

∴ VW = XY

→ Let us find its length and its width

∵ Points W and X have the same x-coordinates

∴ y1 = -9 and y2 = 4

→ By using the 4th note above

∴ WX = 4 - -9 = 4 + 9 = 13  

∴ L = 13 units

∵ Points X and Y have the same y-coordinates

∴ x1 = -1 and x2 = 3

→ By using the 3rd note above

∴ XY = 3 - -1 = 3 + 1 = 4  

∴ W = 4 units

→ By using the formula of the area above

∵ A = 13 × 4

∴ A = 52 square units

∴ The area of the rectangle VWXY is 52 square units

Answer:  √117

Step-by-step explanation:

Since no diagram present, am assuming hypotenuse AB and right angle C.  Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.

a^2 + b^2 = 22^2 (Pythagorean)

Using Pythag on two smaller triangles,

x^2 + 13^2 = a^2

x^2 + 9^2 = b^2

Substituting in first equation,

x^2 + 13^2 + x^2 + 9^2 = 22^2

x^2 = 117, so x = √117
