Choose the equation of the horizontal line that passes through the point (-8 -7)

1 answer:

4 0

The equation of a horizontal line is $y=$ . So all you have to do it plug in the y-value to that, so it would be:

$y=-7$

Write the polynomial of least degree with roots -2, 0, 1.

joja [24]

So since -2, 0, 1 are the roots:

Therefore x = -2, x = 0 , x = 1

Implies that:

x = 2 x - 2 = 0

x = 0 x = 0

x = 1 x - 1 = 0

Therefore (x - 2)x(x - 1) = 0

(x - 2)(x - 1) = x(x - 1) - 2(x - 1) = x² - x - 2x + 2 = x² - 3x + 2

(x - 2)x(x - 1) = 0

(x - 2)(x - 1)x = 0

(x² - 3x + 2)x = 0

x*x² - x*3x + x*2 = 0

x³ - 3x² + 2x = 0

This is the polynomial with the least degree, because it possible for another polynomial with higher power to still have the same root.

x³ - 3x² + 2x = 0 is the polynomial.

I hope this helps.

jessie sorted the coins in her bank. she made 7 stacks of 6 dimes and 8 stacks of 5 nickels. she then found 1 dime and 1 nickel.

To find out how dimes you multiply 7 and 6 and you get 42 dimes
and it says she finds one nickel so you have 1 nickel

Hope this helps!!!

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%. By what percent must t

Sergeu [11.5K]

Answer: 28 %

Step-by-step explanation:

Let, Initially,

V be the volume of construction work

r be the productivity of labor

n be the number of days

x be the number workers.

Thus, V = r × n × x ------------(1)

Now, According to the question,

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%.

Therefore,

Final volume of the work = 160% of V = 1.6 V

Final productivity = 125% of r = 1.25 r

Also, the time is same in both conditions,

Final time taken = n

Let y be the number of people after changes.

Thus, 1.6 V = 1.25 r × n × y -----(2)

Dividing equation (1) by equation (2)

We get, y = 1.60 x/1.25

Thus, the changes in the number of workers

= $\frac{(\frac{1.60x}{1.25}-x) }{x}\times 100$

= 0.28 × 100

= 28 %
