Triangle ABC is similar to triangle DEF.

Answer:

Step-by-step explanation:

The water level decreases 2 gallons every 3 seconds describes the rate of change shown in the grap

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given that Ariel is emptying the water from a 10 gallon cooler.

The graph shows the water level in the cooler as she empties it

Rate of change is change in water to change in time

(3, 8) and (0, 10) are the points from graph

Rate of change  = 10-8/0-3

=-2/3

The minus sign is showing that is is decreasing

The water level decreases 2 gallons every 3 seconds

Hence, the water level decreases 2 gallons every 3 seconds describes the rate of change shown in the graph.

Step-by-step explanation:

Right Isosceles Triangle

Side a = 9

Side b = 9

Side c = 12.72792 = 9√2

Angle ∠A = 45° = 0.7854 rad = π/4

Angle ∠B = 45° = 0.7854 rad = π/4

Angle ∠C = 90° = 1.5708 rad = π/2

Answer: The volume is the product of the Length, Width, and Height: V = LWH.

Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.

Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2

Using the distributive property and moving the constant to the left gives:

W2 + (3 in.)W - 40 in.2 = 0

This factors:

(W + 8 in.)(W - 5 in.) = 0

The first factor gives W = -8 in. which is nonsense because it is negative.

The second factor gives a valid answer of W = 5 in.

The exact value of the cotangent of theta in simplest radical form is -21/20.

What is the simplest radical form?

The simplest radical form is the expression of a radical without any factors inside the radical that can be further simplified.

To find the exact value of cotangent of theta, we need to find the values of cosine and sine of theta first.

Given that the terminal side of the angle passes through the point (21,-20), we can use the Pythagorean theorem to find the hypotenuse of the right triangle formed by the angle and the x and y-axes:

[tex]h = \sqrt{(21^2 + (-20)^2)} = \sqrt{(841 + 400)} = \sqrt{(1241)}[/tex]

Then, we can find the values of cosine and sine of theta using the x and y-coordinates of the point:

cos(theta) = adjacent/hypotenuse = 21/sqrt(1241)

sin(theta) = opposite/hypotenuse = -20/sqrt(1241)

Now we can find the value of cotangent of theta:

cot(theta) = cos(theta) / sin(theta) = (21/sqrt(1241)) / (-20/sqrt(1241))

= -21/20

Therefore, the exact value of the cotangent of theta in simplest radical form is -21/20.

Answer:

[tex]\huge \purple {\boxed { m\angle C = 47\degree}} [/tex]

[tex] \huge \red {\boxed { \widehat{BC}=96\degree}} [/tex]

Step-by-step explanation:

By inscribed angle theorem:

[tex] m\angle C = \frac{1}{2} m(\widehat{AD}) [/tex]

[tex] \therefore m\angle C = \frac{1}{2}\times 94\degree [/tex]

[tex]\huge \purple {\boxed {\therefore m\angle C = 47\degree}} [/tex]

Again by inscribed angle theorem:

[tex] m\angle A = \frac{1}{2} m(\widehat{BC}) [/tex]

[tex] \therefore 48\degree = \frac{1}{2} m(\widehat{BC}) [/tex]

[tex] \therefore 48\degree\times 2 = m(\widehat{BC}) [/tex]

[tex] \huge \red {\boxed {\therefore m(\widehat{BC}) =96\degree}} [/tex]

Answer:

x=9/4,x=-9/4

Step-by-step explanation:

16x^2−81=0

Step 1: Add 81 to both sides.

16x^2−81+81=0+81

16x^2=81

Step 2: Divide both sides by 16.

16x^2/16 = 81/16

x^2 = 81/16

Step 3: Take square root.

x = ±√81/16

x=2.25,x=−2.25

Convert to fraction form.

x=9/4,x=-9/4
