Answer:

\log_{10}(147) = 2.1673

Step-by-step explanation:

Given

\log_{10} 3 = 0.4771

\log_{10} 5 = 0.6990

\log_{10} 7= 0.8451

\log_{10} 11 = 1.0414

Required

Evaluate \log_{10}(147)

Expand

\log_{10}(147) = \log_{10}(49 * 3)

Further expand

\log_{10}(147) = \log_{10}(7 * 7 * 3)

Apply product rule of logarithm

\log_{10}(147) = \log_{10}(7) + \log_{10}(7) + \log_{10}(3)

Substitute values for log(7) and log(3)

\log_{10}(147) = 0.8451 + 0.8451 + 0.4771

\log_{10}(147) = 2.1673

What is X I need help i dont know how to do this
Anit [1.1K]

Answer:

x = 75

Step-by-step explanation:

Triangle BDH

The angle must add to 180 degrees

36+ 39 + DHB = 180

75 + DHB = 180

DBH = 180-75

DHB = 105

DBH + x = 180 since it is a straight line

105+ x = 180

x = 75

PLEASE HELP ME PLEASE!!!
dimaraw [331]

Answer:

Step-by-step explanation:

Let's just check something out before we continue to fill in the blanks.

The zeros are (x - 1) and (x -5)

y = (x - 1)(x - 5)            Remove the brackets.

y = x^2 - 6x + 5          Complete the square

y = (x^2 - 6x + 9) + 5 - 9

y = (x - 3)^2  - 4

So we have a minumum at (3, - 4)  Now we can go through the rest of the questions.

Part A

(1,0) and (5,0)

Part B

The vertex is (3, - 4) See the completed square above.

Part C

It's a minimum. It is the point between the two roots on the x axis. The vertex drops below the x axis.

Part D

The axis of symmetry goes through the x value of the minimum.

x = 3

The answers are all in parts A B C D. I leave you to figure out where to put them.  You should be able to do that.

A 10-mL graduate weighs 42.745 g. When 5 mL of distilled water are measured in it, the combined weight of graduate and water is
Bingel [31]

Answer:

The measured weight of the water = 4.93 g

The percentage error in measured value = 1.4%

Step-by-step explanation:

Given:

Weight of the 10-mL graduate = 42.745 g

Combined weight of graduate and 5 mL water = 47.675 g

5 mL of water should weight = 5 g

thus, actual value of 5 mL water = 5 g

Now,

The measured weight of the water

= (Combined weight of graduate + 5 mL water) - Weight of the 10-mL graduate

= 47.675 g - 42.745 g

= 4.93 g

The percentage error in measured value

= \frac{\textup{Actual value-calculated value}}{\textup{Actual value}}\times100

= \frac{\textup{5-4.93}}{\textup{5}}\times100

or

= 1.4%
