Mathematics
1 answer:
Maksim231197 [3]2 years ago
4 0

Step-by-step explanation:

x³ - 4x² - 25x + 100k

= x²(x - 4) - 25(x - 4k)

= (x² - 25)(x - 4k)

= (x + 5)(x - 5)(x - 4k)

Hence the other 2 zeroes are x = -5 or x = 5.

Write the standard form of the equation of the circle with center (8,−1) that passes through the point (6,7)
marshall27 [118]

Answer:

(x - 8)^2 + (y + 1)^2 = 68

Step-by-step explanation:

The standard form of the equation of the circle with center (8,−1) is :

(x - 8)^2 + (y + 1)^2 = R^2

If the circle passes through the point (6,7) that means that the point (6,7) is a solution of the equation and we can replace (x,y) with (6,7) to find R.

A light bulb consumes 960 watt-hours per day. How many watt-hours does it consumes in 4 days and 18 hours?
MaRussiya [10]
960 watts = 24 hours

4 days = 96 hours

960 (watts) x 4 (days) = 3840 watts

12 hours= 480 watts

6 hours = 240 watts

18 hours = 720 watts

3840 (4 days) + 720 (18 hrs) = 4560

2 variable inequalities from their graphs . Please answer. Ty!
Alexus [3.1K]

Answer:

y≤\frac{1}{3} x+1

Step-by-step explanation:

Since the graph is facing down, We know the equation is y<mx+b

Since slope is rise/run the slope is 1/3.

Since the y intercept (The point where the line hits y) is 1, the equation is

y<1/3x+1

BUT WAIT!

The line is solid meaning that we have to include the line as part of the values. This will make the new equation

y≤\frac{1}{3} x+1
