Spent = 5(19) + 3(199)

Mary spent $692

The endpoints of EF<br> are E(1,3) and F(-2,8).<br> Find EF.

Phantasy [73]

Answer:

EF = $\sqrt{34}$ ≈ 5.83

Step-by-step explanation:

Calculate EF using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)

EF = $\sqrt{(-2-1)^2+(8-3)^2}$

= $\sqrt{(-3)^2+5^2}$

= $\sqrt{9+25}$

= $\sqrt{34}$ ≈ 5.83 ( to 2 dec. places )

lakkis [162]

Answer: R2280

Step-by-step explanation:

Total crates = 10

Bottles in one crate = 12

Total bottles = 10 x 12 = 120

Price of 1 bottle = R19

Price of 120 bottles = R19 x 120 = R2280

The population of bobcats in northern Arizona since 2008 can be modeled using the function b(t) = –0.32t2 + 2.7t + 253. What doe

Vesna [10]

Answer:

See below.

Step-by-step explanation:

t represents time (probably years).

The population of bobcats can't be negative, so negative values in the range do not make sense.

The function is continuous, but you're probably only looking at discrete values.
