Answer:

So the answer is 2^-3

Step-by-step explanation:

The principle is the same no matter what the base.

Log_2 (7) + Log_2(3/28) - Log_2(6)

+ means multiply

- means divide

Log_2(7 * 3/28 /6)

Log_2(7/6 * 3/28)

Log_2(1/2 * 1/4)              3 divides into 6 twice. 7 divides into 28 four times

log_2 (1/8)

This is equivalent to 2^(-3)

Answer:

80m²

Step-by-step explanation:

area of rectangle-&10m×6m=60m²

10m-6m=4m

10m×4m=40m²

area of triangle->40m²÷2=20m²

area->60m²+20m²=80m²

Answer:

120 ohms

Step-by-step explanation:

Given data

Voltage= 60 volts

Current= 0.5 amps

Power of bulb= 60 watt

We know that from Ohms law

V= IR

Make R subject of the formula

R= V/I

R= 60/0.5

R= 120 ohms

Hence the resistance is 120ohms

Answer:

Step-by-step explanation:

A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.

y=mx+b

For the top line I found two points (5,200) and (30,325)

m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5

y=5x+b, using point (5,200) we can solve for b

200=5(5)+b, b=200-25=175 so the line is

y=5x+175

For the bottom line we have points (5,50) and 10,100)

m=(100-50)/(10-5)=50/5=10

y=10x+b, using point (5,50) we have

50=10(5)+b, b=50-50=0 so

y=10x

Answer:

b=8

Step-by-step explanation:

Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.

we are given the line y=-3x-5

we need to find the slope of the new line. To do that, we can use this equation:

-3m=-1

divide by -3 on both sides

m=1/3

so the slope of the perpendicular line is 1/3

We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need

so far our equation is:

y=1/3x+b

we need to find b

we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b

so:

7=1/3(-3)+b

7=-1+b

8=b

so the y intercept of the line is 8; as a point it's (0,8)

hope this helps!

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches

Answer:

$32.1

Step-by-step explanation:

First find out what 25% of 40 is:

$40 x .25 = $10

Take the answer and subtract that from the original price:

$40 - $10 = $30

Next, take the sales tax (7% or 0.07) and multiply that by the new price:

$30 x 0.07 = $2.1

Lastly, take the answer and add that to the new price:

$30 + $2.1 = $32.1

Then you would get your answer:

$32.1

Answer:

both

Step-by-step explanation:

they are both correct. sin and cosine are complements (90-x) of each other ( that's where cosine gets its name).
