Answer:

Set up trig ratio using tangent.

Tan theta = opp/adj

Tan theta = 500/800

Tan^-1 (500/800) = 32 degrees

Answer: 476m²

Step-by-step explanation:

Find the area of the triangle and then subtract it from the area of the rectangle.

Area of triangle = 1/2 * base * height

= 1/2 * 8 * 6

= 24m²

Area of rectangle:

= Length * Width

= 25 * 20

= 500m²

Area not covered by garden:

= 500 - 24

= 476m²

Answer:

283

and you have your answer.

Answer:

P(P, then Y)=(1/11)(1/10)=1/110

Step-by-step explanation:

The number of letters in probability is 11.

There is 1 P.

The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11.  Thus:

Probability of drawing a P on the first draw is 1/11.

There are now 10 letters left. There is 1 Y. so

Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.

The probability of drawing a P on the first draw and a Y on the second draw is

(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)

P(P, then Y)=(1/11)(1/10)=1/110

Answer:

[tex] 687.5 \: {ft}^{2} [/tex]

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

[tex] = {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2} [/tex]

Answer:

x > 3/2

Step-by-step explanation:

2x - 3 > -4x + 6

Add 4x to each side

2x+4x - 3 > -4x+4x + 6

6x-3 > 6

Add 3 to each side

6x-3+3>6+3

6x>9

Divide each side by 6

6x/6 >9/6

x > 3/2

Answer:

Step-by-step explanation:

x^9 + 3x^8 +2x^7 +4=0

Hey,I'm not sure enough...i guess if the highest power is 9 then we get 9 roots..sorryvif I'm wrong:')

Answer: Quadratic Function: A function with the highest power of variable as 2.

Vertex: The lowest or highest point on the graph of a quadratic function.

Two Types of Problems: Finding quadratic function (a) given the vertex and another point; and (b) given three points.

Answer:

[tex]\displaystyle \cos(2x)=-\frac{7}{25}[/tex]

Step-by-step explanation:

We want to find:

[tex]\displaystyle \cos(2x)\text{ given that }\sin(x)=-\frac{4}{5}[/tex]

And x is in QIII.

Recall that sine is the ratio of the opposite side to the hypotenuse.

Therefore, the adjacent side is (we can ignore the negative for now).

[tex]a=\sqrt{5^2-4^2}=\sqrt{25-16}=\sqrt{9}=3[/tex]

So, the adjacent side is 3, the opposite side is 4, and the hypotenuse is 5.

Using the double angle identity, we can rewrite:

[tex]\cos(2x)=\cos^2(x)-\sin^2(x)[/tex]

Since x is in QIII, cosine is positive, sine is negative, and tangent is negative.

Using the above values, we can conclude that:

[tex]\displaystyle \cos(x)=\frac{3}{5}\text{ and } \sin(x)=-\frac{4}{5}[/tex]

Substitute:

[tex]\displaystyle \cos(2x)=\Big(\frac{3}{5}\Big)^2-\Big(-\frac{4}{5}\Big)^2[/tex]

Evaluate:

[tex]\displaystyle \cos(2x)=\frac{9}{25}-\frac{16}{25}=-\frac{7}{25}[/tex]

Answer:

The answer is 24/7

Answer:

3.428

Step-by-step explanation:

Given:

Principal value = 40000

Rate of compounded interest = 20%

Time = 2 years

To find:

The interest.

Solution:

Formula for amount is

[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]

Where, P is principal, r is rate of interest and t is time in years.

Putting the given values, we get

[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]

[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]

[tex]A=57600[/tex]

Now, the formula for interest is

[tex]I=A-P[/tex]

[tex]I=57600-40000[/tex]

[tex]I=17600[/tex]

Therefore, the amount of compound interest is 17,600.

Answer:

-3

Step-by-step explanation:

Using the Triangle Sum Theorem, we can prove that m<A + m<B + m<C = 180⁰. Looking at the triangle above, it has given us two measurements. We have to find the third measurement. In order to find the third measurement we will use the Triangle Sum Theorem.

m<A + m<B + m<C = 180⁰

x + 83 + 60⁰ + 40⁰ = 180⁰

x + 183⁰ = 180⁰

x + 183⁰ - 183⁰ = 180⁰ - 183⁰

x = -3

Now plug in -3 in the x place.

x + 83

-3 + 83 = 80⁰

Let us make sure that our Triangle Sum Theorem is right.

m<A + m<B + m<C = 180⁰

80⁰ + 60⁰ + 40⁰ = 180⁰

180⁰ = 180⁰

So this makes our answer true. Hope this helps, thank you :) !!
