Answer:

\frac{9}{4}

Step-by-step explanation:

Hi there!

3*\frac{3}{4}

Rewrite 3 as a fraction

= \frac{3}{1} *\frac{3}{4}

Multiply the numerators and the denominators

3*3=9\\1*4=4

= \frac{9}{4}

I hope this helps!

Find a polynomial function of lowest degree with real coefficients having zeroes of 2 and -Si (Show all work to earn credit.)
antoniya [11.8K]

Answer:  The required polynomial of lowest degree is p(x)=x^3-2x^2+25x-50

Step-by-step explanation:  We are given to find a polynomial function of lowest degree with real coefficients having zeroes of 2 and -5i.

We know that

if x = a is a zero of a real polynomial function p(x), then (x - a) is a factor of the polynomial p(x).

So, according to the given information, (x - 2) and ( x + 5i) are the factors of the given polynomial.

Also, we know that complex zeroes occur in conjugate pairs, so 5i will also be a zero of the given polynomial.

This implies that (x - 5i) is also a factor of the given polynomial.

Therefore, the polynomial of lowest degree (three) with real coefficients having zeroes of 2 and -5i is given by

p(x)=(x-2)(x+5i)(x-5i)\\\\\Rightarrow p(x)=(x-2)(x^2-25i^2)\\\\\Rightarrow p(x)=(x-2)(x^2+25)\\\\\Rightarrow p(x)=x^3-2x^2+25x-50

Thus, the required polynomial of lowest degree is p(x)=x^3-2x^2+25x-50

Helppp. Write an equation to solve for a. Then find the missing angle.
kvasek [131]

Answer:

180 = 90 + 52+ a

38 =a

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

180 = 90 + 52+ a

Combine like terms

180 = 142+a

Subtract 142 from each side

180 -142 = 142+ a -142

38 = a
