Answer:

Step-by-step explanation:

By definition, the constant of proportionality is a constant ratio of two variables that are proportional. So the answer is a . The constant ratio of one variable quantity to another to which it is proportional (or the Unit Rate).

Someone pls help plsssss?? ASAP pls

1)First, understand that whatever your equation is it’s always gonna be less than 100, because she doesn’t wanna get more than 100 ft.
*>100
2) remember that Lainey already dropped 20 feet. The amount of minutes is your unknown variable (x)
3) so, note that the rate is 20 ft/minute. If you multiply 20 by the amount of minutes she has to descend (your unknown variable: x) you cancel out the “minutes” in the 20 ft/minute fraction.
(Ex. 20ft/min *multiply* x [unknown]minutes= 20ftx)
This is what you want since you need all of the terms to be the same unit to solve with algebra.
4) so, to put it all together you have, 20 times x (representing the unknown amount of minutes) plus 20 (representing the amount she has already fallen) is greater than 100

* 20x+20>100

The height of a tree trunk is 20 meters and the base diameter is 0.5 meter. a. The wood has a density of 380 kilograms per cubic

blsea [12.9K]

Originally,
h = 20 m, the height of the tree trunk
d = 0.5 m, the diameter of the trunk

Because the density is 380 kg/m³, the mass of the trunk is
$m= \frac{ \pi }{4} (0.5 \, m)^{2}(20 \, m)(380 \, \frac{kg}{m^{3}} ) = 1492.3 \, kg$

Answer: 1492.3 kg

After one year:
After the tree puts on a growth ring, the new diameter is
d = 0.5 + 2(4 x 10⁻³ m) = 0.508 m
The tree grows by 0.2 m, s the new height is
h = 20 + 0.2 = 20.2 m

The increase in volume is
$\Delta V= \frac{ \pi }{4} (0.508 \, m)^{2}(20.2 \, m) - \frac{ \pi }{4} (0.5 \, m)^{2}(20 \, m) = 0.1672\, m^{3}$

Answer: The volume produced is 0.17 m³ (nearest hundredth)

List all possible rational zeros for each polynomial function.

kykrilka [37]

For

$P(x)=3x^3-2x^2+5x-2$

all possible rational zeroes are all the possible factors of the constant term -2 express over coefficient of the term with the highest degree of the polynomial which is 3

These are

$\frac{-1}{3}, \frac{1}{3},\frac{-2}{3}, \frac{2}{3}$

For

$R(x)=12x^3-17x^2-27x-30$

all possible rational zeroes are all the possible factors of the constant term -30 express over coefficient of the term with the highest degree of the polynomial which is 12

These are

$\frac{-1}{12}, \frac{1}{12},\frac{-1}{6}, \frac{1}{6},\frac{-1}{4}, \frac{1}{4},\frac{-5}{12}, \frac{5}{12},\frac{-1}{2}, \frac{1}{2},\frac{-5}{6}, \frac{5}{6},\frac{-5}{4}, \frac{5}{4},\frac{-5}{2}, \frac{5}{2}$
