The significance of an exponential function

e⁻³ in your calculator, which gives you 0.03337327...

Since you need 4 decimal places, you need to look at the 5th decimal place. If it's 5 or more, you add 1 to the 4th decimal place. If it's less than 5, you leave the 4th decimal as it is.

In this case, the 5th decimal place is 7 and the 4th is 3. Since 7>5, the 4th decimal place changes from 3 to 4.

The equation of the line will be y = 2x - 2.

A linear equation with a degree of one is referred to as a line equation. Two variables, x, and y are present in the equation of the line. The third parameter is the line's slope, which indicates the line's elevation.

The general form of the equation of the line is given as:-

y = mx + c

Given that the equation of the line is passing through the point ( -2,0) and the slope of the line is 2.

The equation of the line will be calculated as:-

y = mx + c

-2 = 0 + c

c = -2

y = mx + c

y = 2x - 2

Therefore, the equation of the line will be y = 2x - 2.

The height of the candle which is a linear function with respect to time after 12 hours was 25.2 centimeters.

A linear function has a graph of a straight line.

Given that height of a candle is a linear function of the amount of time in hours it has been burning.

The slope(m) is = - 0.4 which is = -(4/10) = - (2/5).

The height of the candle after 19 hours is 22.4 centimeters, which can be written as two points (x,y) = (19,22.4).

Now to obtain the height of the candle first we have to form an equation of a line in slope intercept form to find y-intercept(b), which is,

y = mx + b.

22.4 = -(2/5).19 + b.

22.4 = -7.6 + b.

b = 22.4 + 7.6.

b = 30.

∴ y = -(2/5)x + 30.

Now to obtain the height of the candle after 12 hours we have to substitute 12 in x.

So, y = -(2/5)(12) + 30.

y = 25.2 centimeters.

If he plans to spend 200 per month, then the number of months he can make withdrawals from his savings account until his balance is zero dollars is equal to 5.

First, we calculate the money earned by Nick in 6 months

Money earned per month = $400

Money earned in 6 months = 400 × 6 = 2400

If he spends $250 out of the money earned per month, then the money spent in these 6 months can be calculated as follows;

Money spent per month = 250

Money spent in 6 months = 250 × 6 = 1500

Now we calculate the money put in the saving account in 6 months by subtraction;

Money added to the saving account = 2400 - 1500 = $900

As he already had $100 in the saving account,

Total amount of money in the saving account = 900 + 100 = 1000

If he plans to spend 200 per month, then the number of months he can make withdrawals can be calculated by division

Number of months = total money in the account ÷ money spent per month

Number of months = 1000 ÷ 200 = 5

Therefore, Nick can make withdrawals for 5 months from his savings account.

q3: -9, 1

q4: No

The reason there are multiple answers for this question is because of the absolute value sign. to solve this you can isolate the absolute value onto one side and solve for the positive and negative possibilities.

step 1: isolate the absolute value

|3(x+4)|+8=23 ----> |3(x+4)|=15

step 2: remove the absolute value sign the remember that now it has two answer possibilities where 15 can be both negative and positive and still be right. Then just solve just like you would a normal equation.

3(x+4)= +-15 ----> x+4= +-5

x = -9, 1

It is given that 3 cos² 2x / ( 1 - sin 2x) = 1

3cos² 2x / ( 1 - sin 2x) = 1

As we know sin²x + cos²x = 1

3 ( 1 - sin²2x) / ( 1 - sin 2x) = 1

3 - 3 sin²2x = 1 - sin 2x

3 sin²2x - sin2x - 2= 0

As we know sin2x = 2 sin x. cos x

3( 2 sin x. cos x)² + 2 sin x. cos x  - 2 = 0

Let's take sin x . cos  x = t

3 ( 2t)² - 2t - 2 = 0

12t² - 2t - 2 = 0

12t² - 6t + 4t - 2 = 0

6t( 2t - 1) + 2(2t - 1) = 0

(6t + 2)(2t - 1) = 0

t = -1/3 , 1/2

Now put the value of t we get

sin x . cos x = -1/3 , 1/2

2 sin x . cos x = -2/3 , 1

sin 2x = -2/3 , 1

It is given that x should be between 0° to 90°.

Therefore

sin 2x = 1

sin 2x = sin 90°

2x = 90°

x = 45°

Therefore the value of x is 45°

the answer is in the question, but If that isn't what you meant to type, 2 3/4 - 1/4 is 2.5

The corresponding growth factor of +70% is 1.7

The formula for the annual rate of change is

                    1 ± r             (1)

where r = rate of change

and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.

According to the question we have been given the growth that is +70%. Since there is plus sign therefore it is a growth factor.

Thus, r = + 0.7

Putting this value in equation (1) we get

The price of the cheaper vehicle is $39,000

From the question, we are to determine the price of the cheaper vehicle

Let the cost of one of the cars b $x

and the cost of the other car be $y

From the given information,

The total price for two cars at a dealership is $108,000

That is

x + y = 108000   ----------- (1)

and

one car’s price is $9000​ less than twice the other

x = 2y - 9000       ----------- (2)

Put equation (2) into equation (1)

x + y = 108000

2y - 9000 + y = 108000

2y + y - 9000 = 108000

2y + y = 108000 + 9000

3y = 117000

y = 117000/3

y = 39000

∴ The price of one of the vehicles is $39,000

Substitute this value into equation (2)

x = 2y - 9000

x = 2(39000) - 9000

x = 78000 - 9000

x = 69000

The price of the other vehicle is $69,000

Hence, the price of the cheaper vehicle is $39,000

If a long run athlete can run 1/2 km in 3 minutes then he can run 10 km in an hour.

Given, a long distance athlete can run 1/2 kilometer in 3 minutes.

How much distance can he cover in an hour = ?

How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.

Time = 60 minutes.

we know that 3 minutes = 1/2 km

therefore, distance covered in an hour = 1/2 ÷ 3/60

= 1/2 × 60/3

= 1/2 × 20

= 10

distance covered in an hour = 10 km.

hence we get the distance covered by the athlete in an hour as 10 km.
