Writing it in the form of a+bi we get 0+4i

Step-by-step explanation:

We need to evaluate expression -16 squared and write the result in form a+bi

The given expression is: $\sqrt{-16}$

We know that $\sqrt{-1}=i$

We know that 16= 4x4 = 4^2

Putting values:

$\sqrt{-16}=\sqrt{-1}\sqrt{16}\\=\sqrt{4^2}i\\=4i$

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i

HELP ME QUICK: Suppose AB has one endpoint at A(0, 0). If (5, 3) is the midpoint of AB, what are the coordinates of point B?

DiKsa [7]

Answer:

Step-by-step explanation:

If P is midpoint of AB and: $A(0,\,0)\,,\quad P(5,\,3)\,,\quad B(x_B,\,y_B)$

then:

$x_P-x_A=x_B - x_P\qquad\quad\ \wedge\qquad y_P-y_A=y_B - y_P\\\\ 5-0=x_B-5\qquad\quad\wedge\qquad 3-0=y_B -3\\\\ x_B=5+5\qquad\qquad\wedge\qquad\ \ y_B=3+3 \\\\ {}\quad x_B=10\qquad\qquad\wedge\qquad\qquad \ y_B=6$

Answer:

38,325 dinners.

Step-by-step explanation:

We have been given that last year the manager of a health care facility served 36,500 dinners. The manager estimates an increase of 5% in the number of dinners to be served next year.

The estimated number of dinners next year would be 36,500 plus 5% of 36,500.

$36,500+(\frac{5}{100}\times 36,500)$
