8 0

y =x^2 +3

to find the inverse interchange the x and y and solve for y

x = y^2 +3

subtract 3 from each side

x-3 = y^2

take the sqrt of each side

+-sqrt(x-3) =y

How do I multiply 89 x 38 by using partial products? PLEASE ANSWER FAST
olga_2 [115]

Answer:

The result after partial products of 89 x 38 is 3382

Step-by-step explanation:

We need to solve 89 x 38 using partial products.

In Partial products we divide each term such that 89 can be written as 80 and 9 while 38 can be written as 30 and 8

We will multiply each term with other and then find their sum.

Multiplication is shown in figure attached.

Now adding the results of each cell in the table:

2400+640+270+72= 3382

So, the result after partial products of 89 x 38 is 3382.

If J is the centroid of cde, de=52, fc=15, he=14, find each missing measure
const2013 [10]

Answer:

DG = 26

GE = 26

DF = 15

CH = 14

CE = 28

Step-by-step explanation:

The figure has been attached, to complement the question.

DE = 52

FC = 15

HE = 14

Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:

DF = FC

CH = HE

DG = GE

Solving (a): DG

If DG = GE, then

DE = DG + GE

DE = DG + DG

DE = 2DG

Make DG the subject

DG = \frac{1}{2}DE

Substitute 52 for DE

DG = \frac{1}{2} * 52

DG = 26

Solving (b): GE

If DG = GE, then

GE = DG

GE = 26

Solving (c): DF

DF = FC

So:

DF = 15

Solving (d): CH

CH = HE

CH = 14

Solving (e): CE

If CH = HE, then

CE = CH + HE

CE = 14 + 14

CE = 28
