Answer: A = letter 1 in alphabet

E = letter 5 (fifth one along from start)

F = letter 6

H = letter 8

then go in reverse:

Z = letter 26

V = letter 22 (or 5th one along from end)

U = letter 21 (next one back)

S = letter 19 (skip one as there was between F and H but going backwards)

E = letter 5 (fifth one along from start)

F = letter 6

H = letter 8

then go in reverse:

Z = letter 26

V = letter 22 (or 5th one along from end)

U = letter 21 (next one back)

S = letter 19 (skip one as there was between F and H but going backwards)

Log x + log 7 = log 37

assume log base 9

log(x+6) - log(x) - log(2) = 0

log((x+6)/(2x)) = 0

(x+6)/(2x) = 1

x+6 = 2x

x = 6

log(x+6) - log(x) - log(2) = 0

log((x+6)/(2x)) = 0

(x+6)/(2x) = 1

x+6 = 2x

x = 6

WILL GIVE BRAINLIEST! Write the general equation for the circle that passes through the points: (1, 7) (8, 6) (7, -1)

Answer:

Step-by-step explanation:

General Equation Of A Circle

If a,b, and c are real numbers, then the general equation of a circle is

There are three unknowns that could eventually be determined if we knew three points of the circle. These points are (1, 7) (8, 6) (7, -1). We only need to replace them in the general equation and solve the resulting system of equations

For the point (1, 7)

Operating and rearranging

For the point (8, 6)

Operating and rearranging

For the point (7, -1)

Operating and rearranging

We form the system of equations

We'll eliminate c from the first two equations and then from the last two equations

Multiplying the first one by -1

Adding them up we have

Adding up with the third equation

We get

c=0

Knowing this value, let's return to the original system with c=0

Multiplying the first by -8

Adding them up

Which gives

Finally, isolating a from

We get

a=-8

So the general equation of the circle is

Alice process health claims. it takes her an average of 10 minutes to check the paperwork on one claim. At that rate,how long will it take her to process 20 claims

To solve this you simply multiply the number of minutes it takes to review one claim times the number of claims.

10 x 20 = 200

10 x 20 = 200

Ravi is riding his bicycle. He takes 6 hours to ride 76.8 kilometers. What is his speed?

Answer:

12.8km/hr

Step-by-step explanation:

Distance = 76.8km

Time = 6 hours

Speed = distance ➗ time

Speed = 76.8km ➗ 6 hours

Speed = 12.8km/hr

Help please Which equation shows the substitution method being used to solve the system of linear equations?

x + y = 6

x = y + 2

A.

x = (x – 6) + 2

B.

x + (y + 2) = 6

C.

(y + 2) + y = 6

D.

x + y = y + 2

We can substitute y + 2 for 'x' in the first equation, giving us:

(y + 2) + y = 6

(y + 2) + y = 6

C, you substituted the y in the x place

5. Find the interest earned. Assume 3.5% interest compounded daily.

$975 deposited April 23 and withdrawn June 18

$6.66

$5.25

$5.16

$6.75

Interest earned can be calculated using the following equation:

I = P{(1+r/n)^t-1}

Where, I = Interest earned, P = Amount deposited, r= Interest rate (annual) = 3.5% = 0.035, n = 365 days, t= time in days = 55 days (deposit and withdrawing days are not counted).

Therefore,

I = 975{(1+0.035/365)^55 -1 ) ≈ $5.16

I = P{(1+r/n)^t-1}

Where, I = Interest earned, P = Amount deposited, r= Interest rate (annual) = 3.5% = 0.035, n = 365 days, t= time in days = 55 days (deposit and withdrawing days are not counted).

Therefore,

I = 975{(1+0.035/365)^55 -1 ) ≈ $5.16
