Answer:

What he did right was doing the first part correctly, wher it;s 46000x1.05, which is 48300. But then the student thought that every year, Carlos' salary will increase by 48300, and after 3 years it got to 144900, which is nuts. The real thing is to do 46000 x 1.15, because on the 3rd year, your salary will be 115% of your salary, if that makes sense, you do 5x3 = 15, then you add 15% to 100 which is 115 % =1.15. then you do 46000x1.15= 55545$

hope that answers your question

Answer:

The student correctly used a rate of r = 1.05 to find the new salary, not just the amount of the increase.

The student incorrectly multiplied by 3 instead of raising r to the third power.

The correct answer is $50,715.

Step-by-step explanation:

1*10+32(2+4+6)+76+2^3

First parenthesis

1*10+32(12)+76+2^3

Next exponents

1*10+32(12)+76+8

Next multiplication

10+384+76+8

Then add

394+84

Add

478

Answer:

x = √30

Step-by-step explanation:

From small triangle BDC:

using Pythagorean theorem

CB² = BD² + DC²

x² = BD² + 3²

Fron triangles BDC and ADB.

ΔBDC has long leg BD and short leg DC.

ΔADB has long leg AD and shirt leg BD.

AD : BD = BD : DC

7 : BD = BD : 3

7*3 = BD*BD

BD² = 7*3 = 21

x² =  BD² + 3² = 21+9 = 30

x² = 30

x = √30

Answer:

  y = -1/6x +2

Step-by-step explanation:

The black vertical line in the middle of the graph is the y-axis. The blue line crosses it a the point marked 2. This is known as the y-intercept.

The slope of the line is the ratio of "rise" (vertical change) to "run" (horizontal change).

There is a marked point on the line at the y-intercept, where x=0 and y=2. There is another marked point to the right of that, where x=6 and y=1.

The vertical change between those two points is 1 -2 = -1.

The horizontal change between those two points is 6 -0 = 6

The slope is then -1/6.

__

The slope-intercept form of the equation of a line is often written as ...

   y = mx + b

where "m" is the slope (-1/6), and "b" is the y-intercept.

Using the values we found above, the equation of the line is ...

  y = -1/6x +2

Solve -5 √x =-15<br> A. X= -9<br> B. X= -7<br> C. X= 9<br> D. X= 7
Leokris [45]
Divide both sides by -5
You would then get (square root)x=3 since the negatives would cancel out
Then you square both sides
You will be left with (x)*2=(3)*2
Your answer will be C. X=9
Hope that helped!
