Answer:

Pythagoras theorem) 85^2 = 77^2 +|XY|^2. Step 2 |XY|^2 = 7225 - 5929, = 1296. Get square root to find value or length of the line XY.= 36 units. Tan Y = opposite ÷ adjacent = 77÷36. Angle in degrees = Tan^(-1)(77÷36) = 64.94 degrees.

Answer:

Step-by-step explanation:

ok, so you tangent is opposite/adjacent. You need to find the adjacent side. You could do a^2+b^2=c^2.A and B are the legs and c is the hypotunese. 85^2-77^2=b^2. This solves to b being 36. This means the adjacent side is 36 and opposite being 77. The tangent of Y is 77/36.

Six plus four fifths A equals nine tenths A

Drupady [299]

6+4/5a=9/10a
make bottom numbers same
into 10
60/10+8/10a=9/10a
minus 8/10a from both sides
60/10=1/10a
multiply both sides by 10
60=a

Use the model from problem 12 to estimate the population of bacteria at 9 hours. Type your answer below. Show your work.

Check the picture below.

that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.

anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.

there are some online regression calculators as well.
