Determine how much time

Mathematics
1 answer:
IgorC [24]2 years ago
7 0

Answer: 11 years

Step-by-step explanation:

You can use the Rule of 72 which is a way to calculate quickly, the time it will take for an investment to double given its interest rate.

It works by:

= 72 / Interest rate

Rate is compounded quarterly so the periodic rate is:

= 6.56%/4

= 1.64%

Time taken to double = 72/1.64

= 43.9 quarters

In years that is:

= 43.9/4

= 11 years

4 - 7/x = 5 + 6/x <br>help me guys <br><br>​
Brilliant_brown [7]

Answer:

x = -13

Step-by-step explanation:

or, (4x-7)/x = (5x+6)/x

or, (4x-7) = (5x +6)

[the x gets cancelled when it comes to opposite side]

or, 4x-5x = 6+7

or, -x = 13

or, x = -13

The depth of water near a boat dock is collected by a buoy. The data shows that the water level reached 11 feet during high tide
Scorpion4ik [409]

9514 1404 393

Answer:

  9.17 ft

Step-by-step explanation:

Put x=12 in the equation and evaluate. (The sine argument is in degrees.)

  y = 1.5·sin(25.72(12 +1.5)) +9.5 = 1.5·sin(347.22) +9.5

  y = -0.33 +9.5 = 9.17

The water will be 9.17 feet deep at noon.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
iren [92.7K]

Answer:

(y+1)

Step-by-step explanation:

use quadratic formula.

you will get two values of y

y= 7/5 and y= -1

u can create factors using these values of y (making 0 subject)

like

for 7/5

7/5=y

7=5y

5y-7=0

zero becomes subject in such cases bcz there are no numbers left on that side

now for -1

-1=y

y+1=0

so your factors are 5y-7 and y+1
