Answer:
y=-2x+12
Step-by-step explanation:
This is an equation in slope-intercept form:
y=mx+b (where m is the slope and b is the y-intercept)
We are given the slope, -2.
y=-2x+b
We plug in the values (5,2):
2=(-2)*5+b
2=-10+b
b=12
The equation is:
y=-2x+12
The number "4" is in the hundreds place. To the right is 7, and since it's greater than five it rounds up. So 16,473 to the nearest hundred is 16,500. Hope this helped!
D. Because you're multiplying 3 by a number which is what the variable represents (n), then you're just adding 7 to that which equals 19 all together. It all translates to 3n+7=19.
Answer:
f(x) = x³ + x² - 5x + 3
Step-by-step explanation:
The cubic polynomial has zeros at 1, 1, - 3.
Therefore, x = 1, 1, - 3 are the roots of the polynomial and hence, (x - 1), (x - 1) and (x + 3) will be factors of the cubic polynomial.
Hence, we can write the polynomial as a function of x as
f(x) = (x - 1)(x - 1)(x + 3)
⇒ f(x) = (x² - 2x + 1)(x + 3)
⇒ f(x) = x³ - 2x² + 3x² + x - 6x + 3
⇒ f(x) = x³ + x² - 5x + 3
So, this is the cubic polynomial function in standard form. (Answer)
1995. 164 million
2001. 169 million
t = 2001 - 1995 = 6
169 =
![p^{6} = \frac{169}{164}= 1.0304878 \\ p = \sqrt[6]{1.0304878}](https://tex.z-dn.net/?f=%20p%5E%7B6%7D%20%3D%20%5Cfrac%7B169%7D%7B164%7D%3D%201.0304878%20%5C%5C%20%20p%20%3D%20%20%5Csqrt%5B6%5D%7B1.0304878%7D%20%20)
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) =

f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be
181 million.
