Answer:

133.5

Step-by-step explanation:

Area of paralleogram is base x height. The base is 15 as given. We need to find the height.

Using triangle MNJ we can find it.

We need to find side MN but we are given an angle adjacent to that side 90. We also given another angle and a side adjacent to that angle 52 and 7 respectively.

We can use law of sines to find MN

\frac{mn}{ \sin(90) }  =  \frac{7}{ \sin(52) }

sin of 90 =1 so multiply 1 by both sides

mn =  \frac{7}{ \sin(52) }  \times 1

simplify that and we get mn=8.9.

So know we can multiply 8.9 by 1t to find the area.

15×8.9=

133.5

2. Andrew made an error in determining the polynomial equation of smallest degree whose roots are 3, 2+2i and 2-2i.
inna [77]

The polynomial equation for the given roots is x³-7x²+20x-24=0.

Given that, the polynomial equation of the smallest degree whose roots are 3, 2+2i and 2-2i.

Now, we need to write the polynomial equation.

<h3>What is a polynomial equation? </h3>

A polynomial equation is an equation where a polynomial is set equal to zero. i.e., it is an equation formed with variables, non-negative integer exponents, and coefficients together with operations and an equal sign. It has different exponents. The highest one gives the degree of the equation. For an equation to be a polynomial equation, the variable in it should have only non-negative integer exponents. i.e., the exponents of variables should be only non-negative and they should neither be negative nor be fractions.

Now, x=3, x=2+2i and x=2-2i

x-3, x-2-2i and x-2+2i

So, the polynomial equation is (x-3)(x-2-2i)(x-2+2i)=0

⇒(x-3)(x(x-2-2i)-2(x-2-2i)+2i(x-2-2i))=0

⇒(x-3)(x²-2x-2xi-2x+4+4i+2xi-4i-4i²)=0

⇒(x-3)(x²-2x-2x+4-4i²)=0

⇒(x-3)(x²-4x+4+4)=0 (∵i²=-1)

⇒(x-3)(x²-4x+8)=0

⇒x(x²-4x+8)-3(x²-4x+8)=0

⇒x³-4x²+8x-3x²+12x-24=0

⇒x³-7x²+20x-24=0

Therefore, the polynomial equation for the given roots is x³-7x²+20x-24=0.

In a game show, players play multiple rounds to score points. Each round has 3 times as many points available as the previous ro
Juli2301 [7.4K]

Answer:

p = 25(3)^n

Step-by-step explanation:

Given

Round 0 1 2 3

Points 25 75 225 675

Required

Determine the equation

Let n = rounds and p = points.

So, we have:

(n_1,p_1) = (0,25)

(n_2,p_2) = (1,75)

(n_2,p_2) = (3,225)

The above shows a geometric progression.

So, we solve using

p = ab^n

In (n_1,p_1) = (0,25)

n = 0 and p = 25

Substitute these values in p = ab^n

25 = ab^0

25 = a*1

25 = a

a  = 25

In (n_2,p_2) = (1,75)

n = 1 and p = 75

Substitute these values in p = ab^n

75 = ab^1

75 = ab

Substitute 25 for a

75 = 25*b

Make b the subject

b = \frac{75}{25}

b = 3

So, we have:

a  = 25 and b = 3

The equation p = ab^n becomes

p = 25(3)^n
